The Goals of HIV Care
The goals of clinical care for people living with HIV are to:
- Provide effective ongoing (life-long) treatment for HIV
- Manage other health issues, co-infections and co-morbidities
- Address any social determinants that could affect the person’s health or ability to stay engaged in care
- Improve overall quality of life.
High quality, consistent and accessible care is essential for people living with HIV. With effective treatment and care, people with HIV can live a near-normal lifespan. Life expectancy for a 20 year-old individual in the U.S. or Canada on combination antiretroviral therapy (cART) may approach that of the general population.1 Fully effective suppression of plasma HIV-1 RNA or viral load (VL) through the use of cART can profoundly reduce mortality and morbidity.2
Some Ontarians with HIV who are on treatment are doing well, but disparities persist. Life expectancy and mortality for individuals accessing cART in Canada differ by sex, injection drug use (IDU) history, Indigenous ancestry, CD4 count before initiating ART, and by time of ART initiation. In general, the life expectancy of people with HIV in Canada remains lower than that of the general population.3
The use of comprehensive HIV care guidelines can improve health outcomes.4, 5 Focusing Our Efforts – Changing the Course of the HIV Prevention, Engagement and Care Cascade in Ontario, the HIV/AIDS Strategy to 2026 released in February 2017, recommended the following to improve the health, longevity and quality of life for all people with HIV:
“… the Ministry of Health and Long Term Care (MOHLTC) will work with HIV providers to:
- Establish standards of care for people with HIV, including the use of care pathways that help people navigate the system and stay engaged in care
- Strengthen HIV care delivery by building needed capacity and better care coordination.”
The guidelines are intended to:
- Optimize clinical management of HIV infection
- Empower patients to be engaged in their care, act as their own best advocates and make informed decisions.
The guidelines set out evidence-based practices to help engage people with HIV in care in a timely way, retain them in care over time, address challenges that may cause them to fall out of care (e.g. access issues, personal, social and economic circumstances, substance use, incarceration,6 depression, distrust of the medical system, trauma, treatment “fatigue,” feeling “well” so not feeling an urgent need to access care 7, 8), assess them for relevant health issues across the life course, and monitor all aspects of their health, including access and adherence to cART.9, 10
These guidelines may be used in any Ontario health care setting where people with HIV access care, including specialty HIV clinics, primary care practices, shared care models, through emergency departments, in long-term care settings and in correctional institutions. They may also be a valuable reference tool for providers new to HIV care, and those working in an evolving provincial healthcare delivery system.11, 12
- These guidelines do not replace professional judgment or decision-making between a patient and provider, alter the privacy of the patient/provider relationship or provide guidance on prescribing any specific cART drug regimen or drugs to manage co-infections or comorbid conditions.
- These guidelines do not include recommendations for caring for infants or children with HIV. Clinicians caring for children with HIV can receive advice and assistance from the two large specialized pediatric centres in Ontario that provide this care. These centres can also provide guidance on early and prompt treatment or pre-emptive combination therapy for high-risk infants. Infants exposed to HIV in utero should receive PEP and be tested for HIV at birth.
At the request of the AIDS Bureau, Ministry of Health and Long-Term Care, the Ontario HIV Treatment Network (OHTN) brought together an interdisciplinary working group, including infectious disease and primary care physicians, people living with HIV, nurses, clinic coordinators, pharmacists, and registered dieticians and social workers (see Appendix B). The group was supported by staff from the AIDS Bureau and the OHTN.
The OHTN HIV Clinical Guidelines Working Group reviewed research evidence and recommendations from guidelines developed in other jurisdictions13–21 and followed recognized principles for evaluating and implementing guidelines produced by others22, 23 – including discussing differences among the guidelines.24 The group did not conduct independent assessments of the recommendations produced elsewhere.
Members identified gaps or recommendations where more evidence was required and examined the available peer-reviewed and grey literature. Where questions or disagreements occurred, members worked with the OHTN’s knowledge synthesis team to conduct additional research and analysis, or considered best clinical judgement.

HIV care and treatment are now routinely measured against the continuum or cascade of care,25 which focuses on improving the number of people diagnosed who are linked to care, retained in care over time, placed on antiretroviral therapy and who achieve and maintain a suppressed – and ideally – an undetectable viral load.
Maintaining an undetectable VL26 is good for individual health because it reduces damage to the immune system, reduces chronic inflammation and inhibits disease progression. It is also good for population health because someone with an undetectable VL is significantly less likely to transmit the virus to others.27 The goal for health systems is to maximize the proportion of people living with HIV who achieve VL suppression as well as other markers of a functioning immune system.28
UNAIDS has established the 90-90-90 targets for the HIV care cascade:
- 90% of people infected with HIV will be diagnosed
- 90% of those who are diagnosed will be on treatment
- 90% of those who are on treatment will be virally suppressed.
In the HIV/AIDS strategy to 2026, Ontario’s HIV sector has made a commitment to achieve the UNAIDS 90-90-90 targets for the care cascade. Fig. 1 illustrates Ontario’s best estimate of its HIV care cascade in 2015.
Figure 1: Estimated Proportion of People with HIV in Ontario at Each Stage of the Care Cascade, 2015
Notes to chart: Percentage of people diagnosed with HIV is based on 2014 modeled preliminary estimates provided by the Public Health Agency of Canada. Percentage on treatment and virally suppressed are based on 2015 data from the Ontario Public Health Laboratory.
Keeping VL Measures in Perspective
While an undetectable VL is a desirable endpoint, it is not enough on its own to ensure the health, well-being and quality of life for all people with HIV. Some people with HIV will not achieve or maintain full VL suppression or will need more intense care to address their specific needs.29 A suppressed viral load is also not enough to assess the health of “immunological nonresponders” (INRs) – people who may achieve and sustain an undetectable VL but whose CD4 counts remain low: a sign that their immune function is still significantly impaired.30, 31 This group – which may account for 10-20% of people with HIV in care in the province — has comparatively poorer health outcomes and requires careful clinical monitoring.
The commonly used HIV care cascade is focused solely on ART treatment and suppressing viral load. It does not include management of comorbidities or promotion of optimal health. To acknowledge that gap, Ontario has developed a broader cascade (Figure 3) that includes primary care and care for other health conditions, co-infections or co-morbidities. It illustrates how people receiving lifelong HIV treatment may experience gaps in care, and it highlights the importance of efforts to retain them, reduce loss to follow-up and, when applicable, re-engage people in care in a timely way.10
Figure 3: The Engagement and Care Cascade for People Living with HIV
Clinical care is not the only factor in improving health and well-being. Biological, individual, social and structural factors also play a role. To encourage comprehensive person-centred care, these guidelines highlight the need for active links to other supports, such as housing, psychosocial care and harm reduction services. As a recent Canadian commentary stated: “a concerning picture emerges when we examine those in care who have multiple psychosocial syndemic risks. Across all populations, those who experience a syndemic of co-occurring mental health and addiction issues are significantly more likely to fall out of care, less likely to adhere to treatment and less likely to achieve/maintain an undetectable viral load.” 32
The guidelines begin with recommendations on the organization and delivery of HIV care.
The guidelines use a “patient journey” approach, beginning with diagnosis and then following the patient from the initial assessment or first visit(s), to initiation of treatment and ongoing care and support – as illustrated in Fig. 3. They focus on the person’s history and life course, and include strategies to reduce/manage co-morbidities and other health issues. The guidelines also include recommendations on ongoing access to cART across the continuum of care
For people living with HIV, the guidelines clarify what they should expect from their providers. For health care providers, the guidelines set out expected assessments, tests and investigations as well as their recommended frequency. They include practical checklists that can be used in real-world health settings to ensure people with HIV receive comprehensive assessments.
The working group will produce separate recommendations on criteria and metrics to measure:
- Individual clinic/practice implementation of the guidelines
- The impact of the guidelines on patient empowerment, satisfaction and health outcomes
- The impact of the guidelines in: increasing the number of people with HIV who are retained in care and achieve health goals (including but not limited to suppressed VL); and in helping Ontario achieve the UNAIDS 90-90-90 targets.
II. List of All Recommendations in Guidelines
These guidelines encourage integrated models of care that involve an interdisciplinary team-based approach. Team members may be located within the health care setting or be part of a broader network of services in the community.
The care of people with HIV may be shared between specialists and primary care providers. When primary care providers refer patients to specialists and when specialists refer patients to primary care providers, both must be clear on their roles (i.e. the aspects of the person’s care that each provider is responsible for) to ensure the person receives comprehensive care.
1.1 Comprehensive HIV care should be provided by an interdisciplinary team of HIV-knowledgeable professionals who can offer integrated care and wellness as well as appropriate and timely linkage or referral to other health and social services. Providers should be aware of the network of services in their area, have easy access to these services, and cultivate relationships to ensure effective referrals and linkages.
Patients have better outcomes when they have access to integrated multidisciplinary care teams.33–36 The team could include physicians, nurses, pharmacists and case managers as well as professionals skilled in psychosocial support, sexual and reproductive health, substance use counselling, mental health expertise (including psychiatric care and psychotherapy), social services navigation, nutrition, rehabilitation services and co-morbidity experts. Depending on the specific clinic/practice and its staffing, team members may be able to provide more than one domain of care. Teams who do not have access to all the recommended professionals/skills should work with available resources to ensure that people with HIV achieve the best possible health outcomes.
1.2 Physicians providing HIV care should be highly knowledgeable and experienced in the management of HIV infection. Physicians who do not have this experience should consult with an HIV-experienced physician.14, 15, 19 This process may include the use of telemedicine,37 mentorship and/or shared care.
People living with HIV have better health outcomes when they are cared for by experienced physicians who have a critical mass of HIV-positive patients in their practice and are able to maintain their HIV care competencies.38–44 HIV expertise may be based on managing a minimum number of patients with HIV (e.g. 25 according to some medical associations, 50 according to another recent study, 20 in another review) and/or ongoing certification.11, 33, 45, 46 This recommendation is especially relevant in Ontario where a substantial number of people with HIV receive their care exclusively from primary care physicians.11Providers who do not have that expertise – particularly those working in settings where people with HIV occasionally access care (e.g. emergency rooms) – have a responsibility to consult with those who do.
1.3 People with HIV and their interdisciplinary clinical care team may benefit from the services offered by community-based AIDS service organizations (ASOs).47 Many ASOs offer practical support services as well as peer-based programs to empower people with HIV to be actively involved in their care and make informed decisions about their treatment.48
Ontario has a network of 33 ASOs that are specifically funded to provide prevention, education and support services for people with or at risk of HIV. ASO services can augment those available through public assistance programs. For patients with complex social needs, the interdisciplinary clinical team can work with ASOs to provide HIV case management, including assistance with engaging/relinking and retaining patients in care, adherence support, appointment reminders, transportation to appointments, counselling related to stigma and disclosure, and support to apply for food programs, housing, access to drug coverage and income supplements.49 Providers can refer patients to an ASO and ASOs can help connect people with HIV with HIV-knowledgeable providers. A small number of Ontario ASOs are co-located with HIV clinics to facilitate case management.47
1.4 Providers should create a trusting/therapeutic relationship with patients.
Specific behaviors and attitudes that facilitate a therapeutic relationship and effective engagement and retention include connecting through being present and attentive, validating through non-judgment and respect, and partnering through collaboration and shared decision-making. Behaviors that are barriers to engagement include patronizing, condescending and demeaning attitudes and communications styles, and being autocratic around decision-making.52 Patients with more avoidant and disorganized coping styles are at greater risk of dropping out of care unless a strong health care relationship and therapeutic alliance is fostered, ideally from the first visit on.53
To elicit patient input about how to enhance therapeutic relationships and quality of care, some Ontario HIV clinics have established an independent patient advisory committee or include patients on quality committees.
1.5 The practice setting should deliver sensitive, culturally competent care to all patients and create an atmosphere of respect, cultural safety, compassion and acceptance.19
Most people living with HIV experience stigma in their daily lives – some traumatically so. To create the trusting patient/provider relationship essential to engage and retain people in care, clinics/practices should provide a stigma-free environment. Providers should reassure patients about the respectful non-judgmental attention they can expect to receive and what the practice will do to safeguard their privacy.14,15, 19, 54 Efforts to reduce stigma and reassure patients may be particularly important in practices with few HIV patients or in locations/communities where individuals may face strong stigma and are fearful about disclosing their HIV status. Especially when partnering with Indigenous peoples to build a therapeutic relationship, providers should respect and validate the patient’s way of knowing and being as part of culturally safe care.55
Providers should be comfortable having candid discussions with patients about sexual activities and patterns of sexual satisfaction. Providers should understand that sexual health involves safe and pleasurable experiences as well as preventing disease.
Providers should also be able to elicit sensitive, frank information regarding patients’ substance use, mental health, sexual abuse and other experiences that may affect their willingness to engage in care. They should respect patients’ need for gender affirmation and understand the consequences of intergenerational trauma and histories of discrimination. The populations most affected by HIV in Ontario are heterogeneous and expect their providers to be knowledgeable about the differences.56–60 (See also Promising Practices for how to use pre-appointment screening and patient surveys to solicit candid information.)
The patient’s first contact and early encounters with the clinical team (i.e. initial linkage to care and assessment) set the stage for sustained care. In these guidelines, linkage to care is defined as a confirmed care visit, with intake by a nurse, nurse practitioner or physician. Simply referring a patient for an appointment is not considered linkage to care.
2.1 Every effort should be made to link people to care and complete the initial assessment as soon as possible after diagnosis (i.e. when the person receives the first positive test result from a public health laboratory). Providers should be actively engaged with testing services, clinics and public health institutions in their community that facilitate linkage to care.19
Connection to care soon after HIV diagnosis is associated with improved survival.61, 62 Completing the patient’s initial assessment and establishing the trusting relationship needed for ongoing care will likely take more than one visit. All the visits required to complete the patient’s initial assessment should be scheduled as quickly and efficiently as possible, taking into account the emotional reactions many patients may have when first coming to terms with an HIV diagnosis and the fact that both patients and providers may find it challenging to complete the initial assessment within a short period of time. (See checklist of the tests, exams and evaluations that are part of a comprehensive initial assessment and at other key stages of care.)
2.2 Ontario HIV testing sites should provide people who test positive with post-test counselling and practical information to facilitate linkage to care. Providers should collaborate with testing sites to develop and communicate this information.
Every person in Ontario who tests positive for HIV should receive practical, easy-to-read information that explains the importance of connecting to care and accessing HIV treatment and how to access care. Testing sites should have strong working relationships with HIV care providers to help ensure effective referrals and linkages (preferably warm hand offs) to care.
One of the biggest challenges in linking newly diagnosed people to care is finding a physician/clinic that is taking new patients. To overcome this barrier, providers may keep testing sites apprised of their ability to take on new patients or be available for referrals. To ensure that the initial referral results in a true linkage to care (i.e. confirmed visit and complete assessment), providers may adopt protocols such as updating patient contact information at each visit, scheduling appointments to make them convenient for the patient and sending reminders for the first visit(s).63, 64 Post test counselling also facilitates linkage to care.65
Strength-based case management services can increase the proportion of people with HIV who are successfully linked to care. To help patients connect to care, providers may consider referring them to ASOs for counselling, assistance with transportation and peer outreach – although the evidence on the impact of these interventions is not strong. U.S. research on linkage to HIV care has identified an effective ASO-based intervention – Anti-Retroviral Treatment and Access to Services (ARTAS) – that could be adapted for the Ontario context.67
2.4 Within 2 weeks of receiving a positive HIV test result, newly diagnosed people should be seen by either an experienced HIV physician or other health care provider who will order the initial laboratory workup.15, 20 When test providers suspect a person has been diagnosed in the very early stages infection, they are strongly encouraged to arrange a physician appointment within 1 to 2 days.
Because of the benefits of early cART for people with HIV, every effort should be made to ensure that anyone who is newly diagnosed sees a physician within 2 weeks. An immediate response (i.e. within 1-2 days) is critically important for people with very early infection to prevent damage to their immune system and preserve/strengthen immune function.
If providers are experiencing delays seeing patients (i.e. longer than 2 weeks after diagnosis), they may consider working with local testing sites to improve the linkage and referral processes in their area. When physicians who have less experience in HIV care decide to refer newly diagnosed patients to a more experienced HIV physician, they should provide the patient’s records to the new practice as promptly as possible and no longer than 2 weeks after requesting the referral.
2.5 Evidence of HIV infection based on antibody testing or other confirmatory serologic test should be documented in the patient’s medical record. When practical, providers should ascertain whether the infection is recent and the time of exposure.
When a patient transfers into a practice, the physician should have either written confirmation of their HIV infection or repeat the HIV test.13–17, 19 [IDSA- strong/moderate; BHIVA 2011- IIA, IIB and III; BC- AIII] When indicated, tests to determine primary or acute infection can include nucleic acid amplification testing in the absence of positive antibody detection (or detectable HIV-1 RNA or p24 antigen in serum or plasma in the setting of a negative or indeterminate HIV-1 antibody test result.) A presumptive diagnosis of acute HIV-1 infection can be made on the basis of a negative or indeterminate HIV antibody test result and a positive HIV-1 RNA test result. When a low-positive quantitative HIV-1 RNA result is obtained, the HIV-1 RNA test should be repeated using a different specimen from the same patient.13
2.6 The initial assessment should include:
- A comprehensive past and present medical history, physical exam, medication/psychosocial/family history, review of systems and evaluation of sexual and reproductive health and substance use.14–17, 19
- Confirmatory serology, genotyping and testing for immune markers such as CD4 and VL
- Screening for co-morbidities and other STIs
- Other labs to help manage ART regimens and other risks
- A social needs assessment
- Individual and partner counselling.
The focus of the initial assessment is to collect baseline data, gauge the patient’s reactions to a new diagnosis, start educating the patient about care and initiate treatment to stabilize the HIV infection. Initial data collection assists in selecting an appropriate cART regimen and identifying any need for referrals to other services.
During the initial assessment visits, patients should not be overwhelmed with complex health instructions or immediate plans to address non-acute or lifestyle issues such as smoking cessation or chronic bone health. Information about these issues should be recorded on the patient’s chart and addressed at an appropriate time.
Providers should give first priority to critical factors that affect the initial choice of cART regimen, such as patient access and adherence to medication, acute significant risks, primary social contexts and co-infections including: drug/opioid use, other STIs, threats to personal safety, housing (including both homelessness and unstable housing), food security, and drug and health care insurance coverage.
Newly diagnosed patients may need support to cope with the stress of learning about their HIV infection. This support can be provided by many providers, including nurses, peers, ASOs and social workers. Providers may consider assessing patients who have great difficulty adjusting to the diagnosis for new or existing depression.
2.7 Providers should use the comprehensive medical history and exams, review of systems and evaluation of sexual and reproductive health and substance use to establish baseline values, help manage HIV over the short and long term, and identify other health issues, risks and comorbidities.14–17, 19 When prescribing initial treatment for patients who use substances, providers should know the drugs or substances the patients use so they can identify possible drug interactions and assess the effect of substance use patterns on adherence.68
Along with diagnostic data, comprehensive histories, exams and reviews provide baseline information that may influence decisions about which drug regimens to prescribe based on risk and toxicity factors. They may help determine the intensity of monitoring and management of comorbidities the person requires, and assess both the cause of related conditions and preferred interventions.
Addictions and substance use (which often occur syndemically with mental health issues) are a barrier to optimal health outcomes.32 During the initial assessment – and periodically throughout ongoing care – providers should assess patients’ substance use to avoid drug interactions or adherence issues.
Note: When a primary care provider refers a patient to an HIV specialist, the primary care provider may gather most of this baseline data.
See the following recommended sample histories, screens and exams:
- Medical/family history –- from IDSA and BC
- Physical exam – from IDSA/ HRSA
- Medication/vaccination history- from IDSA
- Initial depression and mental health screens with validated short and ultra-short questionnaires (i.e. as few as two questions) that may indicate whether the patient would benefit from a referral for a full mental health assessment. Ultra-short screens may use as few as 2 questions.69, 70
- Review of Systems – from IDSA and BC
- Substance use (i.e. tobacco, alcohol, and drugs – including illicit use of prescription drugs) – from IDSA
- Sexual/reproductive health – from Public Health Agency of Canada and BHIVA, British Association for Sexual Health and HIV (BASHH) Faculty of Sexual and Reproductive Healthcare (FRSH) guidelines and UK tables for taking sexual history71–73
2.8 All patients diagnosed with HIV should receive: a CD4 test, a repeated quantitative HIV RNA test (viral load) and viral genotypic resistance testing (using the first available VL sample). Screening for sensitivity indicated by HLA-B*5701 is also recommended.13
Increasing evidence supports testing to determine CD8 counts and the CD4/CD8 ratio at initial testing as a predictor of risk for non-AIDS related adverse events — although testing for CD8 counts is not routinely recommended.13, 74 Patients identified in the very early stages of infection (i.e. especially within the first days, weeks and up to 6 months) should be tested and evaluated for laboratory values as promptly as possible and guided into follow-up care without delay. Providers should discuss with patients the purpose of all tests (e.g. to guide cART therapy) and emphasize early-on mutual decision-making as part of active treatment.
2.9 All patients should receive baseline screening for a variety of other infectious agents, including other sexually transmitted illnesses to assess need for counselling, immunization, monitoring or treatment, and to inform HIV management.13–16, 19 Patients should be screened for the following pathogens:73
- Tuberculosis — using tuberculin skin testing or interferon-gamma release assay. A chest x-ray is recommended for those with increased TB risk to determine active infection for treatment.
- Hepatitis A, B, and C – including Hepatitis A total antibodies testing (or IgG), Hepatitis B surface antigen, surface antibody and antibody to total core antigen (HBV DNA testing if positive) and Hepatitis C antibody test and confirmation RNA testing for those who test positive. Note: In Ontario, testing algorithms may be affected by Public Health Laboratory75 ordering requirements. For patients who are severely immunosuppressed, it is not unreasonable to consider screening using both a screening Hepatitis C antibody test and a PCR test as, on rare occasions, the Hepatitis C antibody test may be negative while the PCR test is positive.
- Syphilis – using a treponemal test with confirmatory testing by RPR, TPPA and FTA-ABS.76, 77
- Gonorrhea/chlamydia – using culture and NAAT testing (urine for males, urine or cervical swab for females). Extragenital testing (rectal, pharyngeal swabs) should be performed in persons with HIV who engage in oral or anal sex.77, 78
- Toxoplasma gondii — using Anti-Toxoplasma IgG testing and counseling to avoid new infections
- Cytomegalovirus (CMV) — Anti-CMV IgG.
- Cervical or anal pap smear, depending on geographic availability
- Varicella zoster — using Varicella IgG for those without history of chickenpox or shingles.
- Measles/rubella — if no documentation of prior measles or vaccination.
2.10 Comprehensive biochemistry and other testing (e.g. liver and renal function, dyslipidemia, CBC, organ system injury, blood pressure, diabetes risk) is recommended to support management of ART toxicities and to evaluate chronic disease, cardiovascular risks, frailty and neurocognitive risks.17
2.11 Patients should receive a social needs assessment and be referred to services that can assess and assist with: applying for disability, health insurance and drug coverage; housing, employment (including episodic employment) and food security; and social support and spiritual or personal coping strategies.19
Social services can also address other barriers to accessing care, such as immigration status, literacy and language, proximity to care and location. Housing (including services to address homelessness and unstable or insecure housing) and health insurance and drug coverage are first stage services urgently needed by people newly diagnosed with HIV.79
Social and economic factors and other determinants are associated with clinical outcomes. For example, improving housing stability has been shown to facilitate adherence to treatment for people living with HIV and has other beneficial effects on overall health and well -being.80 Recent findings from the OHTN Cohort Study (OCS) show that people with HIV who are adversely affected by social determinants of health have significantly worse health outcomes even if they are engaged and retained in care. Robust coordination of social and economic assessments are essential to address the interactions of HIV infection with aspects of daily living.81 The social factors that affect health are even more significant for migratory populations, patients transferring between health care settings and people who move in and out of the prison system; they exacerbate the risk of falling out of or avoiding care.
2.12 All patients should be assessed for income/poverty issues, using the clinical tool developed by the Centre for Effective Practice and endorsed by the Ontario College of Family Physicians.
Poverty increases the prevalence and mortality of many diseases, including cardiovascular disease, diabetes, cancer, depression and chronic obstructive pulmonary disease. It accounts for 24% of person years of life lost in Canada. Income inequality is associated with the premature death of 40,000 Canadians per year.82 Poverty disproportionately affects racialized Canadians, Indigenous peoples, people with disabilities, the elderly, women and children.
Poverty is a risk factor that warrants intervention. Poverty is not always apparent: in Ontario 20% of families live in poverty.83 The poverty assessment tool developed by the Centre for Effective Practice in collaboration with the Ontario College of Family Physicians and the Nurse Practitioners Association of Ontario84 recommends that: everyone be screened for poverty (i.e. do you ever have difficulty making ends meet at the end of the month?”); the care team consider testing anyone who screens positive for poverty for diabetes and take poverty into account in determining how aggressive to be in ordering investigations into possible health problems (e.g. cardiovascular disease, cancer, mental illness and stress); and the care team intervene by educating patients and connecting them to programs that can help mitigate poverty (e.g. Canada Benefits, filling out their tax returns, legal resources).85
2.13 All patients, regardless of sex, gender, sexual orientation or age, should be assessed for any risk of intimate partner violence, trauma, abuse or other serious personal safety concerns. The HIV care team should have established referral protocols for patients experiencing violence.19, 86
Patients require time and trusted relationships with their providers to feel comfortable responding to questions about abuse. During the initial assessment visits, a single empathetically delivered question may begin a discussion that continues later. As trust develops, patients may disclose more. Clear questions defining types of abuse may help patients understand reportable experiences.87, 88 Several Ontario health units have adopted the Routine Universal Comprehensive Screening Protocol for Women Abuse (RUCS).89The OHTN Cohort Study has developed a gender neutral tool to screen for intimate partner violence.
2.14 Patients and their sexual or drug use partners should receive culturally appropriate counseling related to the risk of HIV transmission.
Patients should be encouraged to notify their sexual and drug use partners and understand both provider-assisted and public health processes for partner notification. They should also be counseled on strategies to reduce the risk of transmitting the virus and given information on/access to prevention methods for themselves and their partners (e.g. testing and awareness, behavioral adaptations, use of condoms, pre-exposure prophylaxis, voluntary male medical circumcision, STD control).64 All efforts to notify and counsel partners should take into account issues such as the patient’s personal safety (i.e. risk of violence), stigma and other complications related to disclosing HIV status.
Every encounter with patients – beginning with the initial assessment – is an opportunity to reinforce strategies to reduce the risk of HIV transmission and to discuss disclosure, provide advice on measures (including harm reduction) that patients can use to protect themselves from exposures to other strains of HIV or other pathogens, and offer referrals to legal experts (e.g. HIV & AIDS Legal Clinic Ontario – HALCO) who can explain criminalization laws, partner notification and other related issues.
2.15 Women of child bearing age should be screened for trichomoniasis and rubella, all women with HIV should receive a cervical pap test annually, with follow-up colposcopy or biopsy if abnormal, and women over 50 should have a mammogram.14, 48
Cancer Care Ontario screening guidelines call for cervical pap tests every 3 years for women without HIV, but annual testing for immunocompromised women. Despite these recommendations, women with HIV often receive suboptimal screening. Screening should commence at age of sexual initiation and continue throughout a woman’s lifetime.90, 91
2.16 Asymptomatic gay, bisexual, two-spirit men and other men who have sex with men should be evaluated for lymphogranuloma venereum (LGV) when they: test positive for HCV, HIV or any other STI; have a history of engaging in unprotected anal or oral group sex; and/or have a history of travelling to or residing in an area of Canada or abroad where LGV prevalence is high. Their meningitis vaccine history should also be reviewed.;
2.17 Urinalysis and creatinine clearance or eGFR is recommended for African, Caribbean and Black men.17
2.18 A test for glucose-6-phosphate dehydrogenase deficiency is recommended for African, Caribbean and Black men and for men from India, SE Asia and the Mediterranean.17
2.19 When prescribing initial treatment for patients who use substances, providers should know the drugs or substances the patients use so they can identify possible drug interactions and assess the effect of substance use patterns on adherence.68
“Near term” follow-up is the series of visits in the first year after diagnosis and assessment (i.e. 1, 3, 6, 9 and 12 months). During this period, clinics/practices implement and assess the person’s HIV care plan and conduct any other diagnostics that may contribute to the patient’s overall care, health and wellbeing.
INITIATION OF ANTIRETROVIRAL THERAPY
3.1 Patients who are willing and able should initiate combination antiretroviral therapy (cART) as soon as possible after diagnosis.
Early treatment with and ongoing adherence to cART improves individual health and reduces the risk of HIV transmission. Recent findings from the START Study92 and the TEMPRANO trial93 show that people infected with HIV have a considerably lower risk of developing AIDS or other serious illnesses if they start taking antiretroviral drugs sooner: that is, when their CD4 T-cell count is higher rather than waiting until the CD4 cell count drops to lower levels.28, 92, 93
Note: Medical care is founded on principles of patient autonomy and respect for personal dignity. Patient empowerment and shared decision-making may contribute to improved adherence with cART.94 Because people with HIV may have significant trepidation about starting cART, the decision should be made by the patient without coercion. To support the person’s decision-making, providers should provide the best available scientific evidence on the risks and benefits of cART. Clinicians should also take time to answer any questions and address patients’ concerns, and to explore any structural or personal barriers to cART.
3.2 Patients with very early stage (acute) HIV infection should be counselled about the benefits of starting cART as soon as possible (i.e. before the acute infection becomes chronic).
Initiation of cART during very early stages of infection may reduce the size of latent reservoirs of HIV and promote physiological conditions that make it more likely the person will benefit from strategies to cure infection or achieve remission.95–98 These strategies are currently in the early stages of basic, preclinical and preliminary clinical study. Other benefits of treatment in the very early stages of HIV infection include: preserving immune function, reducing morbidity and reducing the risk of onward transmission.48, 99
3.3 Physicians should review initial laboratory values and select an appropriate cART regimen, taking into account the patient’s other comorbid conditions (if any), use of other drugs and access issues.
3.4 Once the patient’s HIV infection is stable, the HIV care team should establish a regular schedule to monitor the patient’s physical and mental health, medication, family history, sexual history and substance use.16
3.5 Clinics/practices should establish a laboratory monitoring schedule for each patient based on the patient’s decision to initiate or delay cART, any concerns about virologic failure, drug toxicity and immunological response, and the need to manage ongoing care.
Some individual clinics/practices have reduced the scope or frequency of laboratory testing for stable adult patients (i.e. CD4 helper cell count in normal reference range and VL suppression for >2 years on cART) who are highly adherent to treatment and at low risk of adverse syndemic issues. At one Ontario clinic, for example, routine follow-up laboratory work for stable patients consists of tests or analyses for CBC, random glucose, ALT, HIV VL and eGFR. At least one Ontario clinic has developed medical directives designed to curtail unnecessary laboratory testing without compromising patient care (consistent with the Choosing Wisely100 initiative – a campaign to help clinicians and patients engage in conversations about unnecessary tests and treatments and make smart and effective choices to ensure high-quality care). Clinics that have these directives or protocols are encouraged to share their testing experience with other practices. Pilot programs to reduce frequency of testing may inform recommendations in future revised guidelines.14, 101–103 Reduction of CD4 testing for INR may not be advisable.
3.6 Because people with HIV are at risk of developing other co-morbidities, providers should consider using comprehensive or combination measures (e.g. VACS Index, EuroSIDA risk score, ASCVD) to monitor for early signs of risk of co-morbidity and/or mortality.104–107
People with HIV are at risk of developing other comorbidities. To provide effective preventive care, providers should use a range of measures to monitor patients for early signs of comorbidity.
3.7 Screening for co-infections and STIs, including hepatitis should be repeated at regular intervals as needed. Most patients should be screened annually for syphilis; patients at high risk (e.g. some men who have sex with men, sex workers) should be screened every 3 to 6 months. Sexually active men and women with multiple partners should be screened annually for chlamydia/gonorrhea.108
For the convenience of both patients and providers, many clinics integrate screening for co-infections and STIs with regularly scheduled VL testing.
3.8 Bone health testing should be conducted in accordance with current OREP guidelines.
To evaluate and manage low bone mineral density, osteoporosis and fracture risk in people with HIV, providers may follow the same principles as for the general population – although some expert practitioners recommend that formal assessment of bone health should commence at an earlier age for people with HIV (i.e. 40 vs 50). In some Ontario clinics, bone health testing is a lower priority than screening for other comorbidities if fractures are infrequent.109 Recent guidelines to assess bone health and risks of fracture or frailty prepared by the Osteo Renal Exchange program (OREP) provide evidence-based consensus on suitable tests for men and women of different ages.110
3.9 Neurocognitive assessments may be appropriate within 6 months of a confirmed HIV diagnosis.111
Asymptomatic and mild neurocognitive impairment without evidence of dementia is known to affect medication adherence and daily and social function. Neurocognitive assessment may be useful in differentiating impairments from depression. It may also establish baseline values and make patients more aware of the impact of HIV on their cognition. Ontario currently has limited capacity to perform these assessments, and their value may be limited since there is no recommended biomedical/ pharmacological therapy for mild neurocognitive impairments other than cART.112 However, there is evidence that both physical exercise and brain fitness exercises may help mitigate or manage mild neurocognitive losses.
3.10 Patients should be offered vaccinations consistent with the Public Health Agency of Canada’s Canadian Immunization guides and recommended immunization schedules for immunocompromised patients (e.g. Infectious Diseases Society of America).14, 113, 114
Some providers may not be knowledgeable about the vaccination needs of people with HIV115 and Ontario’s publicly funded immunization programs may not cover all vaccines recommended for people who have HIV.116 See vaccination schedules and information sheets and checklists prepared by experienced Ontario HIV physicians. Although there are few data on the optimal timing of vaccinations, many practitioners favour providing Hepatitis A and B, pneumococcal and zoster or HPV vaccines when patients are virally suppressed. The decision to vaccinate older adults for herpes and varicella zoster may depend on the patient’s CD4 count.113

3.11 Patients should be encouraged to adopt healthy living practices14 and take targeted effective supplements, including:Author: Anita Rachlis. Reviewed by Fred Crouzat, Jean-Guy Baril, Dominique Tessier, Phil Sestak, John Gill and Curtis Cooper.
- Weight bearing and cardiovascular exercise
- Weight control
- Reducing/stopping smoking
- Limiting alcohol intake
- When indicated, supplementation with Vitamin D and calcium.117
The U.S. National Institutes of Health and others recognize the importance of people with HIV maximizing their health and maintaining functional wellness, which is defined as “a person-centered balance between internal (individual responses to stress, illness, medication; personal or cultural behaviors) and external factors (learning new or adaptive strategies for current roles, managing one’s physical, emotional and environmental health) affecting health, and developing action plans toward healthy living and wellness.”
Smoking cessation should be a high priority for patients once their HIV infection is stable. Smoking significantly reduces life expectancy for people with HIV.14, 15, 121 Providers focused on managing HIV may neglect the risk of smoking: in one study less than half of HIV patients discussed smoking or cardiovascular risks with their providers – despite the impact these health risks have on their long-term well-being.122Recent reviews provide comprehensive strategies for physicians and clinics to actively support smoking cessation in people with HIV.121, 123–125 In Ontario, the Positive Quitting partnership has assembled smoking cessation intervention resources specifically for use in HIV clinics.
The American Dietetic Association has developed comprehensive recommendations for nutrition assessment and interventions for persons with HIV.126
3.12 Social service assessments and referrals — especially those related to housing, food security, income support, access to medicine and peer or family support — should be coordinated with medical evaluations and other services, such as mental health care.32 People with HIV receiving case management in community-based mental health services would benefit from integrated care delivered at the community program site that jointly addresses their co-occurring psychiatric, addiction and physical health needs as well as, perhaps, some medical care.127
Studies show that men with HIV receiving case management in community mental health settings have greater unmet needs for food, money, psychological distress and safety needs than men in those care settings who do not have HIV. These results likely apply to all people with HIV in these settings.
3.15 Women should be asked about sexual function/dysfunction.71
3.16 Women of child-bearing age should be asked about their plans and desires regarding pregnancy consistent with Canadian Society of Obstetricians and Gynaecologists of Canada and Canadian HIV pregnancy planning guidelines.14, 17, 128, 129
Pregnancy planning involves partnership considerations and guideline driven activities for both women and men and varies depending on discordant or concordant HIV status.
Pregnant women living with HIV should be made aware that consistent use of cART and avoidance of breastfeeding can reduce the risk of perinatal transmission to < 1%.129
3.18 Annual digital rectal exams are recommended for all HIV+ men who have sex with men, and consideration should be given to anal pap tests or other screening such as PHV DNA testing and high resolution anoscopy.
There is not enough evidence at this time to fully recommend anal pap tests or other screening such as HPV DNA testing and high resolution anoscopy for all HIV+ men who have sex with men.130 However, if these services are available (access is limited at the current time in Ontario), they may be ordered based on clinical judgement.
3.19 Men should be asked about sexual function/dysfunction. Men with decreased libido or erectile dysfunction should be tested for serum testosterone levels.17
These guidelines recommend, based on strong evidence, that patients be offered cART as soon as possible after being diagnosed with HIV. People who are newly diagnosed and ready to access treatment immediately should be supported to do so. However, for many people, diagnosis is an emotional shock and they may find it difficult to make an informed decision to initiate cART quickly. It may also take time to address any factors that may affect a patient’s ability to maintain a cART regimen (e.g. willingness, pharmaceutical access, syndemic factors).
Until there is a cure for HIV, antiretroviral therapy is a lifetime commitment, so patients may need support to manage and adhere to therapy throughout the life course.
Although evidence explains when to start therapy, guidelines can help providers and patients implement cART effectively. Optimal care and services delivery can contribute to adherence. Good provider-patient relationships measured across relevant domains (general communication skill and empathy, overall patient satisfaction, willingness to recommend the physician, physician trust, HIV specific communication regarding cART in the context of daily life experiences and skilled adherence dialogue) improve adherence.33, 50, 131 See Appendix C for a the relevant domains and advice on how to means to survey patients. The US DHHS has developed a tool (Table 13) to help providers improve adherence, which identifies barriers to adherence and provides an adherence issues framework. Note: Patients may not always give candid answers in face-to-face surveys. Clinics/practices may consider ACASI (Audio Computer-Assisted Self-Interview Software) or electronic tablet surveys. (See Section 5.0, Promising Practices.)
Effective adherence support techniques – such as phone or electronic reminders and active follow-up contacts, a strong patient-provider relationship that leads to greater understanding of the patient’s circumstances and beliefs, the use of expert conversation skills and reinvigoration of previously delivered messages – can also used be used to retain patients in care (see Section 5.0). Clinics/practices may find it useful to combine retention and adherence efforts. Note: Some strategies, such as reminder systems, may not be effective for patients with complex needs who, for example, may not have phones or access to the Internet. Technology-based or conventional reminders to take medications may be less effective without solid relationships and patient feedback.
4.1 Providers should obtain relevant laboratory values — such as CD4 T-cell count, VL, CD8 count, viral genotyping, hypersensitivity (HLA-B*57:01), applicable tropism tests and other laboratory values necessary for prescribing — when treatment is initiated.13, 14, 20
4.2 Patients should be fully involved in decisions to select appropriate regimens and initiate cART. Providers must be prepared to: discuss the issues thoroughly in easy-to-understand language; explore the patient’s understanding and beliefs related to the potential benefits and risks of initiating treatment; and assess the patient’s readiness for, acceptance of and commitment to antiretroviral therapy.
In collaboration with experts in physician/patient communication, European guidelines have developed tested interviewing techniques to explore a patient’s readiness to start and adhere to cART (see Appendix C and “Ready4Therapy” 135). Some patients may benefit from motivational interviewing techniques. Key messages to communicate to patients include: the fact that some adverse effects they may experience when first taking cART are temporary; and regimens can be changed if side effects continue.
Providers may make it easier for patients to discuss non-adherence if they explain the reason for the discussion, do not apportion blame, and probe the patient’s preferred types of support.48
4.4 Providers and patients should discuss any barriers to accessing or adhering to therapy when patients start cART and at regular intervals thereafter.
Barriers may include lack of insurance or drug coverage, other medications and supplements the person may be taking, and any mental health or substance use issues that could affect the ability to take cART consistently.14
Supportive partners or patient caregivers may be included in discussions about possible barriers.136 If drug cost is a potential barrier, clinics/practices can ask the government-run Trillium Drug Plan to fast-track the processing of the patient’s application.
4.5 In light of new evidence on the benefits of early treatment, providers should review the findings with any patients who have hesitated to initiate cART and discuss their concerns.137
Adherence to cART is essential for patients to achieve and maintain VL suppression, recover CD4 T-cells, avoid drug resistance, improve overall health and survival, and decrease the chance of onward HIV transmission. However, adherence may wane over time and be influenced by age, personal and social factors, number of years since diagnosis, previous therapy, access, substance use and mental state.132, 138 Provider skill and involvement are crucial to retain patients in care and help them achieve high levels of medication adherence.13 Providers should consider nuanced approaches.
Regimens that have lower pill burdens (e.g. once daily or, at most, twice daily dosing) improve adherence. The development of new single tablet daily regimens may improve adherence; however, their effectiveness will depend on their tolerability for patients and their efficacy in suppressing VL over the long term.139–141
As generic equivalents of compounds now used in single tablet regimens become available, publicly funded drug programs may pressure providers to prescribe the individual components separately – thereby increasing pill burden and possibly having a negative effect on adherence. If the pill burden of generics is significant, providers may need to advocate for non-generic prescriptions for their patients. The prospect of long-acting injectable formulations of cART, now in the research and development phase, may help overcome issues of pill burden but they will create significant new implementation challenges for patients and the health care system.142, 143
4.7 Clinics/practices should implement strategies that support/sustain adherence, including managing drug interactions between cART and other medications and/or substances the patient uses,13, 16, 48and making effective use of nurses, social workers and community-based counsellors.
A number of strategies, either singly or in combination, have been shown to support adherence (see table) – although most studies were conducted in small populations or unique settings and may not be broadly applicable throughout Ontario.144, 145 For example, the use of clinical pharmacists in ambulatory care or in-patient medical centers improves adherence; however, data about the benefits of using community pharmacists is lacking.146 Working with pharmacists may improve prescribing practice by focusing attention on interactions between cART and other medications and with a variety of drug classes including illicit substances.13, 147, 148 When feasible, patients may also use medication apps, such as Liverpool HIV iChart149to understand drug interactions.
Nursing staff, social workers and community based counsellors are key providers in improving adherence.

|Strategy||Evidence from Guidelines or Articles||Notes|
|Education and counseling||IAPAC IAWHO: “essential”||Interventions delivered to individuals over 12 weeks or more and/or targeting practical medical management were successful as evaluated by systematic review. Effectiveness increased when the intervention was combined with weekly text messages and peer support.|
|Individual one-on-one counseling||IAPAC IIACDC, HRSA recommended||Using one or more counselling techniques|
|Group education/counseling||IAPAC IIC|
|Multidisciplinary education and counseling||IAPAC IIIB|

|Smart Phone reminders or SMS/landline or verbal telephone||IAPAC IBWHO Guidelines: strong recommendation/moderate support.
A recent systematic review found support for the efficacy of text messaging.
Several rapid or systematic reviews find low or mixed evidence for smart/cell phone/landline-verbal reminders or texts.
|One systematic review found good positive support for weekly rather than daily text messaging to improve daily adherence. User fatigue may be an issue with sustainability of the strategy. Efficacy of text messaging may be increased if the messages are bi-directional, include personalized messages and are matched to dosing schedules. Messages that convey “self-care” questions rather than frank reminders may be beneficial. Marketed medication “apps” have not been sufficiently tested and may require quality review before use.WHO finds little evidence to support other reminders such as alarms, phone calls or electronic diaries. According to pilot phase studies, youth may benefit from use of texting technology.|
|Use of HIV specialist clinical pharmacists||One systematic review found significant improvement in adherence. A retrospective review found significantly higher likelihood of durable VL suppression in treatment naïve patients referred to pharmacist assistance management.||Applicable to ambulatory or in-patient care in a multidisciplinary setting; community pharmacist data lacking.|

Adherence can be particularly challenging for certain populations.
4.8 Clinicians should provide additional adherence support for women during the postpartum period.
During the postpartum period, women with HIV may experience problems with adherence and their VL may rebound. They should receive support with adherence as well as comprehensive case management services before being discharged from hospital and for a period of time after. Women who engage in care within 90 days of delivery are significantly more likely to be retained and to maintain a suppressed VL.19, 21, 151–153
4.9 Clinicians should be aware of emotional and mental health issues that may affect cART adherence in women.
Women may experience strong emotional reactions to physical changes associated with cART, such as fat distribution or changes in adipose tissue. They may also be more likely to experience mental health conditions that affect adherence (e.g. depression, anxiety). These conditions may be linked to previous or ongoing trauma, partner violence or abuse.154
4.10 Individuals who use substances or who have heavy alcohol use may benefit from particular adherence supports, including medication to address opioid dependence and education about cART interactions with substances. Patients should also be encouraged to reduce substance and alcohol use.17, 61
Substance use may impair a patient’s ability to adhere to daily regimens. In some cases, patients may intentionally skip medications when drinking or using substances because of mistaken beliefs about interactive toxicity.155, 156 The World Health Organization’s AUDIT screen may be used to identify high alcohol use.157
RETENTION, RELINKING AND RETURN TO CARE
For people with HIV to achieve optimal health outcomes, they must receive ongoing care over their lifetime. Missed clinic visits and other gaps in care are associated with increased mortality, reduced cART adherence, increased hospitalization and lapses in ability to manage comorbidities.158, 159 Patients, especially those with complex needs, may experience interruptions in care.160
A number of indicators have been proposed to measure patient retention in care, including clinic encounters/visits, timing of VL or CD4 tests, and test results during a calendar year.161, 162 Most recently in Ontario, care engagement in any year was defined as:
- “in care” – at least 1 viral load or CD4 cell count
- “continuous care” – at least 2 viral loads or CD4 cell counts at least 90 days apart.
- “being on ART” – based on prescription medication recorded in medical charts.163
However, laboratory tests and pharmacy records may not provide a complete picture of retention and engagement in care for clinical purposes164 or document co-/multi-morbidity care provided at different locations.
Although there is evidence to support some clinic and provider-initiated retention strategies, there is often not enough data to assess their impact on biological outcomes. Data are also lacking on effective techniques to: re-engage people in care after they have been lost to follow-up; follow patients over many years; or address the needs of specific populations.165–167 The following recommendations include both evidence-based interventions and “promising practices” to enhance retention.
5.1 Clinics/practices should actively and systematically monitor their patients’ retention in care. They may use a combination of actual clinic visits, patient laboratory reports, pharmacy requests and other data in medical records to create a comprehensive retention picture. Systematic monitoring may require multiple ways to track individual data.13, 20
Commonly used retention indicators include attending: at least one clinic visit in a 6-month period; or two visits more than 90 days apart in a 12-month period. The desired frequency of visits may be adjusted for patients who need more intense care. Clinics can also track records of missed or continuous visits. Using more than one tracking measure may enhance capacity to link retention monitoring to VL outcomes.168 Monitoring methods should be clinically meaningful and inform patient follow-up and management (e.g., the expected frequency of visits, considering the patient’s management needs; when to initiate follow-up of missed visits). Indicators of problems with retention or the need for more frequent follow-up include: patient failure to refill prescriptions; interruptions in laboratory requisitions; and/or clinical markers (e.g., low CD4 count, weight loss). Based on the data, providers may tailor retention strategies to individual patients. For example, some older (> age 50) treatment experienced and virally suppressed patients may require fewer visits to be retained in care.169
5.2 Clinics/practices should consider using new data-sharing networks or phone tracing to determine whether a patient who appears to be lost to follow-up may have moved, be receiving care elsewhere (e.g. emergency department, family physician, another clinic) or have died.170
The process of tracing patients who are lost to follow-up will be more efficient and accurate when clinics/practises are able to share information about patients. Increased use of electronic medical records may facilitate tracking. If proper procedures are followed, the information required to determine whether someone is receiving care elsewhere may be shared without breaching patient privacy or confidentiality.
5.3 Providers should use traditional appointment reminders coupled with active phone outreach and/or text message reminders. More contact is especially important for patients who have avoidant coping styles, anxiety or depressive symptoms, or who use drugs or alcohol excessively.171–173
Strategies that enhance personal contact are cost effective and increase retention. Enhanced personal contact consists of:
- Establishing a personal patient-provider relationship in a face-to-face meeting
- Remaining in continuous contact with the patient over the year, through:
- brief face-to-face meetings with the same provider/staff person at each HIV care visit. In these meetings, the staff person gives the patient positive reinforcement for keeping the appointment and responds to questions or concerns about the visit.
- calls to the patient from a staff person between scheduled appointments to maintain contact.
- personal reminder phone calls or text messages to the patient seven days and two days before the next scheduled appointment.
- calling the person within 24 hours of a missed appointment or sending a letter requesting contact.
Using a combination of approaches and confirming patient contact information regularly may reduce loss to follow-up.174, 175 Effective reminder systems require updated and reliable patient contact information. Staff should confirm whether patients have reliable access to phones or experience service disconnection. With the patient’s consent and consistent with agency policy, staff should collect emergency or partner contact information – in case the patient can’t be reached directly.176
5.4 The care team should ask patients about any barriers to retention such as: concerns about drug and health care insurance coverage, transportation issues, competing life responsibilities (e.g. child care), depression or mental health issues, housing instability, substance use and/or patient’s perception of the need for care (e.g. feeling “well”).177–180
These enquiries may best be done by registered social workers, nurses, ASOs, peers and staff. To overcome any barriers and improve retention, clinics/practices should develop patient-centred supports and referrals.
Although retention and adherence issues often overlap, patients may be compliant with one and not the other. For example, patients who are adherent to their medications may feel “well” and decide they don’t need ongoing care, or they may be “reminded” to re-enter care only by an adverse event.181
Patients benefit from regular information/messages that reinforce the connections between retention and health outcomes.7
5.5 Providers should ensure that a trusted patient-provider relationship as well as the clinic experience (e.g. waiting times, office space design, confidentiality and privacy, friendliness and respect, office hours and ease of phone contact) contribute to patient retention. If resources allow, clinics may consider having a dedicated retention specialist.176
Patients are less likely to keep appointments if they face long waits, insensitive care or concerns about privacy. In a study of minority women in a primary care system, factors that enhanced engagement in care included: continuity of care with a single clinician, accessibility of the practice, comprehensive care and coordination of specialty care.182
Another factor that may affect retention is Canada’s laws that criminalize HIV nondisclosure: to seek and remain in care, patients may need education about clinic confidentiality and assurances about the provider’s perspective on confidentiality.183
The following examples may help clinic/practices develop retention strategies:
A) THE AIDS EDUCATION TRAINING CENTER (AETC) ENGAGEMENT TOOLKIT:
The AETC toolkit describes several retention practices including: clinic wide messaging; use of outreach workers or patient navigators; case management; and technology solutions. The toolkit evaluates the strategies and provides links to experts and contacts.
B) PATIENT-REPORTED OUTCOMES MEASUREMENT INFORMATION SYSTEM (PROMIS)
The clinic-based PROMIS Project uses tablet-based questionnaires to capture patient information/risk related to a range health care issues that can affect retention and health outcomes (e.g. substance use, depression). Physicians use the information in real time to improve retention in care. 205,206
C) Los Angeles program – Project Engage184
Project Engage had success using compensation incentives to improve retention; however, a similar patient navigation and compensation program for substance users had only limited short term success.208 Compensation incentives may be difficult to translate to an Ontario setting.
5.6 Clinics/practices providing care to youth/adolescents with HIV – particularly those at risk of being lost to follow-up — should consider using different indicators to measure effective retention, such as more frequent clinic visits per year than for adults.209 Effective retention strategies for youth include targeted outreach to marginalized youth and establishing a “youth-centred” environment of respect and understanding.185, 186
When developing transition plans for youth and adolescents born with HIV and care plans for newly diagnosed young adults, clinics/practices should consider defining retention in care as 4 clinic visits per year during the period when youth are learning to take responsibility for managing their own care.
The relationship between HIV and aging is still unclear. Does a lifetime of HIV and use of cART result in “accelerated” aging? Or are the frequency and burden of conditions associated with aging “accentuated” in people with HIV? Regardless of etiology, the growing number of people with HIV who are >50 – particularly those who acquired HIV much earlier in life (long-term survivors) – require thoughtful clinical management187 that addresses a nexus of health and psychosocial risks, including:
- multimorbidity and related polypharmacy
- comorbidity risks for liver disease (not confined to association with hepatitis), dyslipidemia and cardiovascular disease, kidney impairment or other organ injury, male benign prostatic hypertrophy and some cancers
- “frailty” and “pre-frailty” (weight loss, diminished gait and grip, exhaustion, low energy) and the function loss associated with aging
- long-term effects of “survivorship,” stigma, substance use, and mental health and cognition challenges
- social isolation, economic vulnerability or need for coping skills.187–195
While much of the management of aging-related conditions will be similar in people with HIV as in general population, clinics/practices should target specific health risks faced by older patients with HIV (e.g. hypertension, fecal occult blood testing, CVD, COPD, Type 2 diabetes, cancer, neurocognitive impairments).16, 196 As people with HIV age and receive care at home or in hospitals or long-term care settings, special attention should also be paid to co-infections, depression and substance use.197, 198
5.7 To provide integrated care for people aging with HIV, providers should adopt the principles of geriatric and disability rehabilitation care, ensure their referral network includes geriatric and rehabilitation disciplines, and consider patient-centred values for older adults.199–203
Integrated care teams should take into account the unique needs of older adults with HIV and include gerontology and rehabilitation specialties in their referral networks. Providers should work with patients who have long-term lived experience with HIV to understand their preferences, choices and willingness to undergo procedures as conditions associated with aging multiply. They should also consider the priority the patient places on managing HIV relative to managing other illnesses. Rehabilitation professionals can help patients address issues associated with episodic disability and employment.
5.8 Clinics/practices should provide a comprehensive preventive and health maintenance program to help patients aging with HIV minimize the cumulative burdens, including the loss of physical, cognitive or psychological reserves to manage both HIV and age-related conditions.204
People with HIV experience higher rates of some conditions associated with aging in middle age than the general population. In anticipation of geriatric risks and syndromes, clinics/practices should counsel patients about preventive measures (e.g. lifestyle modifications) before age 50 and offer appropriate immunizations. Studies suggest that cART choice may have an effect on severity of frailty189, 205 (See Appendix C for a table of suggested preventive measures.)
5.9 Clinic/practices should work closely with pharmacists and others in their referral networks to address complications related to polypharmacy and drug-drug interactions in older patients. 202, 206, 207
To manage the co-morbidities associated with aging, a significant number of patients with HIV may take 5 to 9 or more non-antiretroviral medications and require support for adherence with these medications as well as cART. Providers may consider modifying cART regimens to improve adherence to all medications. In addition to considering drug-drug interactions specific to HIV, providers should consult criteria (such as Beers rules) for prescribing medications in older adults.13, 188, 208
5.10 Older patients with HIV should be counselled to complete a durable power of attorney for health care and an advance directive medical instruction form, including their views on preferred care settings during advanced disease.13, 188
5.11 Providers may offer support/strategies to help aging patients maintain or improve coping skills, reduce social isolation, stay active in their communities and enhance perceptions of self worth.
Many older patients with HIV become disconnected from others and lose their sense of self worth and purpose. While social isolation is common in all people who are aging, it is often exacerbated in people with HIV because of stigma, loss of friends and mixed emotions about being an HIV survivor. Social isolation and loss of self worth contribute to people falling out of care or giving up practices that enhance health. They are also associated with depression, substance use and geriatric failure to thrive. Conversely, many people with HIV — by virtue of living long-term with the virus — develop strengths and are able to confront challenges, stress and stigma into older age. Techniques to mediate social isolation, improve coping skills and enhance self worth include: mindfulness training, spirituality resources, involvement in social activities and volunteerism, exercise, referral to mental health experts and medication for depression.13, 188, 190, 203, 209–211
5.12 Providers should be sensitive to any issues older patients face related to sexuality and intimacy and address these needs through discussion, counselling, appropriate medication and referrals.188, 212
Postmenopausal women are at higher risk than premenopausal women of progression to cervical squamous intraepithelial lesions.
5.14 Prolonged hormone replacement therapy is not routinely recommended but may be considered for short periods to address severe menopausal symptoms.17
Inside/Out – Incarceration and Release
Current and former inmates of federal or provincial correctional institutions experience syndemic challenges that can significantly impact their care, including: substance use (along with Hepatitis C co-infection), mental health issues, lack of access to coordinated health services and – for newly-released inmates – lack of housing, employment and/or food security. Care transitions can be a particular issue for people who are released into a different community than where they lived before being incarcerated.
Of these issues, mental health issues and lack of housing are the most critical. Although disruptions in HIV care can occur during incarceration (i.e. due to restricted access to medications, transfer between facilities and fear of disclosure), VL suppression rates are high among prisoners – many of whom experience better health outcomes while incarcerated than after release.6, 32, 214, 215 These guidelines recommend strategies to enhance care and health outcomes for people outside the correctional system, recognizing that individuals may cycle in and out of prison.
6.1 Before someone with HIV is released from prison, a comprehensive discharge plan should be developed to address: housing, patient identification/ documentation, health care and drug insurance coverage, first contacts upon release, transportation, records transfer, medical appointments, a 30-day supply of antiretroviral medication, a naloxone kit and opiate substitution (if applicable).6, 19, 216
Peer navigation and case management services can help former inmates develop relationships that will ensure a smooth transition to HIV care in the community. To encourage former inmates to re-link to care in the community, it may help to offer tangible assistance (e.g. connection to primary care and HIV specialist providers, short-term and survival services such as temporary housing and money for food), combined with cultural competency in working with prison populations and a focus on the person’s health care concerns.19, 217 Discharge planning is especially critical if the person’s release occurs just before a weekend or holiday when support services may be difficult to locate.215
6.2 Transition planning for women (including Indigenous women) should incorporate gender sensitive approaches that recognize the importance of relationships, anticipate any risk of post release abuse and address any cultural issues.218
Although women with HIV make up a relatively small number of people who are incarcerated, a high percentage of incarcerated women – especially Indigenous women – have HIV.214
- loss of stable patient/clinic relationships considered “family”
- taking full (adult) responsibility for their health and care
- significant communication barriers between patients and new adult care physicians
- lack of consistent communication between new adult care providers and previous clinic staff
- disconnected, unfamiliar adult services with long waiting times, complex or inconvenient appointments and an intimidating mix of adult patients
- emotional and mental health issues including loss of parents from HIV/AIDS
- developmental/neurocognitive deficits
- problems with cART adherence in the absence of guardian oversight
- chaotic/unstructured lives
- stigma and fear of disclosure to other adolescents especially in the context of maturing into sexual and romantic relationships
- sexual health and safety issues, including experience of abuse
- economic uncertainty, including concerns about cART coverage
- prevalence of drug resistance associated with long-term cART history.
Table 3: Elements of Transition Planning
- Developing an individualized transition plan to address comprehensive care needs including medical, psychosocial and financial aspects of transitioning
- Optimizing provider communication between adolescent and adult clinics
- Identifying adult care providers willing to care for adolescents and young adults
- Addressing patient/family resistance caused by lack of information, stigma or disclosure concerns, and differences in practice styles
- Preparing youth for life skills development, including counseling them on the appropriate use of a primary care provider and appointment management, the importance of prompt symptom recognition and reporting, and the importance of self-efficacy in managing medications, insurance, and entitlements
- Identifying an optimal clinic model for a given setting (i.e., simultaneous transition of mental health and/or case management versus a staged transition)
- Implementing ongoing evaluation to measure the success of a selected model
- Engaging in regular multidisciplinary case conferences between adult and adolescent care providers
- Implementing interventions that may be associated with improved outcomes, such as support groups and mental health consultation
- Incorporating a family planning component into clinical care
- Educating HIV care teams and staff about transitioning
6.3 Before an adolescent is transferred to adult care, the paediatric and adult clinics/practices should develop a structured, cooperative and personalized transition plan that emphasizes communication and support for youth to take responsibility for their health care decision-making.13, 20, 185
Some youth may benefit from a staged transition approach that includes the adult provider visiting the paediatric clinic and the youth and a provider from the paediatric clinic visiting the adult clinic. Nurses and social workers can mediate new appointments (perhaps accompanying patients being introduced to new clinics) and help connect youth (who were likely receiving all their services at the paediatric clinic) to services that may be offered outside the adult clinic (e.g. mental health services, care for comorbidities).
Talking frequently with youth about both transition and care issues can improve the move to the new clinic setting. These conversations should recognize that youth who have lived with HIV since birth have considerable experience with HIV. Providers should use language and terms the youth can understand.
Discussions should explore the young person’s understanding of information in their health records. Providers should spend time confirming that youth understand HIV-related laboratory values and their connection to successful treatment. Regular discussion of reproductive health, contraception and safe sex is also recommended.221, 224–226
6.5 The care team should make particular efforts to help youth improve adherence, including strategies such as individual teachings about responsibility for medical management.
Adherence is a particular issue for young people. One study found that only 50-60% of youth (ages 12-24) with HIV in North America and Europe were substantially adherent to medications.138 Recent OCS findings identified a similar trend in youth in Ontario.163
Other guidelines address clinical care practices to support pregnancy planning and conception among couples where at least one partner has HIV. Those guidelines also outline measures to prevent vertical transmission from HIV-positive mothers during pregnancy (including review of modes of delivery) and the postnatal period.21, 128, 153
These guidelines focus on other care recommendations affecting the health of pregnant women with HIV, especially monitoring. Ideally, care should be managed by both an experienced obstetrician-gynecologist and an HIV specialist. “The goals of HIV management during pregnancy are to maintain and support the woman’s health, provide optimal antiretroviral treatment (ART) to preserve or restore her immune system and suppress viral replication, and to offer interventions that decrease the risk of perinatal HIV transmission.”19
The US DHHS recommends continued monitoring at increased levels of frequency and scope for pregnant women and recommends cART stop/restart rules as follows (including level of evidence):21
- Plasma HIV RNA levels should be monitored at the initial visit (AI); 2 to 4 weeks after initiating (or changing) antiretroviral drug regimens (BI); monthly until RNA levels are undetectable (BIII); and then at least every 3 months during pregnancy (BIII) [More frequent monitoring (monthly) may also be appropriate according to alternative guidelines16]. HIV RNA levels also should be assessed at approximately 34 to 36 weeks’ gestation to inform decisions about mode of delivery and to inform decisions about optimal treatment of the newborn (AIII). [Note: Canadian guidelines state: The woman’s clinical, virological, and immunological statuses should be assessed every 4 to 8 weeks during pregnancy, and again 6 weeks postpartum. (BIII)]129
- CD4 T-lymphocyte (CD4) cell count should be monitored at the initial antenatal visit (AI) and at least every 3 months during pregnancy (BIII). Monitoring of CD4 cell count can be performed every 6 months in patients on combination antiretroviral therapy (cART) with consistently suppressed viral load who have CD4 counts well above the threshold for opportunistic infection risk) (CIII).
- Genotypic antiretroviral drug-resistance testing should be performed at baseline in all HIV-infected pregnant women (BII). Tests should be performed whether the women are antiretroviral-naive or currently on therapy (AIII).
- HIV drug-resistance studies should be performed before modifying antiretroviral regimens for those entering pregnancy with detectable HIV RNA levels that are above the threshold for resistance testing (i.e., >500 to 1,000 copies/mL) while receiving antiretroviral drugs. They should also be performed on women who have suboptimal viral suppression after starting ARV drugs during pregnancy (AII). [Note Canadian guidelines II-2B129]
- Monitoring for complications of antiretroviral drugs during pregnancy should be based on what is known about the adverse effects of the drugs a woman is receiving (AIII).
- HIV-infected women taking cART during pregnancy should undergo standard glucose screening at 24 to 28 weeks’ gestation (AIII). Some experts would perform earlier glucose screening in women receiving ongoing protease inhibitor-based regimens initiated before pregnancy, similar to recommendations for women with risk factors for glucose intolerance (BIII).
- Early ultrasound is recommended to confirm gestational age and, if scheduled cesarean delivery is necessary, to guide timing of the procedure (AII). [BHIVA Women: 1D]153
- In women on effective cART, no perinatal transmissions have been reported after amniocentesis, but a small risk of transmission cannot be ruled out. Amniocentesis should be performed on HIV-infected women only after initiation of an effective cART regimen and, ideally, when HIV RNA levels are undetectable (BIII). In women with detectable HIV RNA levels in whom amniocentesis is deemed necessary, consultation with an expert should be considered (BIII).
- HIV-infected women receiving combination antiretroviral therapy who present for care during the first trimester should continue treatment during pregnancy (AII).
- If an antiretroviral drug regimen is stopped acutely for severe or life-threatening toxicity, severe pregnancy-induced hyperemesis unresponsive to antiemetics, or other acute illnesses that preclude oral intake, all antiretroviral drugs should be stopped simultaneously and ARV therapy should be reinitiated as soon as possible (AIII).
See recommendations regarding pregnant women with HIV and co-infection with hepatitis, considerations for introduction and timing of specific vaccinations, and tables of exams and laboratory measurements.
6.6 During a woman’s pregnancy, members of the team should review any support needs related to food, housing, prospective child care, mental health referral and issues of domestic violence.19
6.7 In addition to being monitored regularly for co-infections common in people with HIV, pregnant women should be screened for history and outbreaks of HSV-2. If they screen positive, they should be offered treatment and suppressive therapy to reduce or prevent outbreaks.22 Screening for other genital infections is also recommended.153
Women with HIV are more likely than women without HIV to experience genital herpes outbreaks. This recommendation helps protect their health and prevent the serious consequences of potential transmission to the fetus. Suppressive HSV-2 therapy may not be recommended in women who do not have a history of genital lesions. Screening for bacterial vaginosis is recommended but the effect of treatment on delivery is uncertain.
6.8 Clinicians should verify and review cART drug resistance testing for pregnant women who acquired HIV perinatally to choose optimal regimens for this cART- experienced group.21
Young women and adolescents who acquired HIV perinatally and reach child bearing age may become pregnant. Their prior cART history can increase chances of drug resistance or adherence challenges that can affect their own health and may increase the risks of vertical transmission.
6.9 Clinics/practices providing services to transgender patients with HIV should integrate transgender treatment recommendations and recognized general primary care protocols into their practice.227 These include step-wise recommendations for assessment and referral guidelines for care informed by a good understanding of hormone therapy (including drug interaction review with cART), gender identity and primary care as adjusted for HIV management.228 Education and empowerment of the individual are also critical.136, 228–230
Many transgender patients with HIV avoid health care providers because they fear insensitive treatment or judgement. Providing comprehensive non-judgemental care may help patients overcome resistance to treatment. A comprehensive response should remove barriers to care affecting transgender patients and include strategies to: support gender affirmation in all interactions; integrate hormone therapy with HIV care; include peer support and transgender staff in clinic settings; and make social service referrals either transgender specific or transgender friendly. Recommended services include:
- HIV-related medical care that includes counselling on prevention of onward secondary transmission and harm reduction
- mental health and substance use screening and services
- transgender-specific care, such as hormone therapy and case management services.59, 231
6.10 Adherence support for transgender patients should include counselling and medical management to address factors that improve adherence.
A study of trans women living with HIV found that excellent cART adherence was associated with age, reduced use of alcohol, high satisfaction with gender expression, importance of gender affirmation, lower stress appraisal of transphobic experiences and excellent adherence to hormone therapy.59
HAPPINESS AND RELATIONSHIPS
7.1 Clinics/practices can offer patients mindfulness-based interventions and/or promote spirituality or other strategies to help them manage stress, enhance coping skills and improve quality of life.190,209, 232–235
A growing body of evidence supports mindfulness-based cognitive therapy, mindfulness-based stress reduction or other techniques to enhance psychological well being and quality of life in people with HIV. Early studies show that these skills can mediate the effects of HIV stigma; however, their effect on other health outcomes requires more evidence. Better health (due to cART), social support and healthy relationships also contribute to a positive sense of self, encourage a forward looking perspective and help normalize living with HIV.
Palliative care is a holistic approach to care that aims to relieve suffering and improve the quality of living for patients with life-limiting diseases and their families, as well as for people at all stages of frailty or chronic illness. It strives to address the person’s and family’s physical, psychological, social, spiritual and practical issues throughout the disease trajectory or the process of aging. Palliative care involves physicians, pharmacists, nurses, psychologists, social workers, physical therapists, and complementary medicine together with primary or specialty care for patients. It includes careful assessment, early identification of any issues, treatment of pain and other problems.
Although HIV clinical care has significantly improved health outcomes, people with HIV continue to die from illnesses common during the pre-cART era or are diagnosed and linked to care late in infection.236, 237 Palliative care should be an essential component of care throughout the course of HIV disease, from asymptomatic stages to the end of life. Palliative care focuses on meeting the person’s and family’s full range of needs, and it reinforces the person’s autonomy and right to be actively involved in his or her own care. Its focus on providing support and relieving symptoms can benefit people dealing with many aspects of serious HIV disease including consequences of addictions, traumas, co-morbidities, homelessness, aging or causes of death (either AIDS related opportunistic infections or so-called non-AIDS defining diseases). The following figure illustrates the integrated approach to palliative and end of life care in the home, hospital, hospice or care residence.
7.2 Clinics/practices should assess patients for pain, including “total pain” (physical, psychological, social and spiritual) to assess their need for palliative care and/or to consult with a palliative specialist or care centre. This assessment should be patient-centred and reflect the patient’s objectives.19, 237–239
Assessment of total pain includes review of physical pain (including neuropathies that interfere with function and may be mitigated biomedically) as well as the patient’s and family’s personal history, mental health, addictions and social circumstances from the perspective of the patient’s goals. Referral should respect the prominent roles of nurses and pharmacists in providing supportive palliative care and take into account the value of integrated, culturally relevant, individualized biopsychosocial as an adjunct to cART. During end-of-life care, the patient and family (with the support of providers) may make decisions about stopping cART if the regimen is no longer controlling symptoms or providing relief. Alleviation of pain and consideration for patient circumstances requires careful balancing and appreciation of unique risk/benefit when prescribing opioid therapy for person who use drugs and are in advanced stages of illness.240 See online directories for palliative care services and providers in Ontario.241
7.3 Consultative palliative and end of life care programs designed to meet the needs of specific populations should put particular emphasis on the patient’s goals and setting of care, harm reduction services, cultural practice, and availability and location of services in rural communities. They should also address the specific needs of people who are incarcerated or in shelters. Providers should review the scope of insurance and coverage for services and palliative care medications as far as possible in advance of when they are needed.215, 242-244.215, 242–244
Palliative and end of life care for Indigenous communities may be affected by location and lack of culturally sensitive home care services. People who use drugs encounter strong barriers to harm reduction services during end-of-life care, which can affect their pain management. Access to palliative care medication for any individual may vary depending on program coverage.
