A population-based study evaluating family physicians' HIV experience and care of people living with HIV in Ontario

Organisation and integrated healthcare approaches for people living with HIV, multimorbidity, or both: a systematic review

BACKGROUND

Universal recommendation for antiretroviral drugs and their effectiveness has put forward the challenge of assuring a chronic and continued care approach to PLHIV (People Living with HIV), pressured by aging and multimorbidity. Integrated approaches are emerging which are more responsive to that reality. Studying those approaches, and their relation to the what of delivery arrangements and the how of implementation processes, may support future strategies to attain more effective organizational responses.

METHODS

We reviewed empirical studies on either HIV, multimorbidity, or both. The studies were published between 2011 and 2020, describing integrated approaches, their design, implementation, and evaluation strategy. Quantitative, qualitative, or mixed methods were included. Electronic databases reviewed cover PubMed, SCOPUS, and Web of Science. A narrative analysis was conducted on each study, and data extraction was accomplished according to the Effective Practice and Organisation of Care taxonomy of health systems interventions.

RESULTS

A total of 30 studies, reporting 22 different interventions, were analysed. In general, interventions were grounded and guided by models and frameworks, and focused on specific subpopulations, or priority groups at increased risk of poorer outcomes. Interventions mixed multiple integrated components. Delivery arrangements targeted more frequently clinical integration (n = 13), and care in proximity, community or online-telephone based (n = 15). Interventions reported investments in the role of users, through self-management support (n = 16), and in coordination, through multidisciplinary teams (n = 9) and continuity of care (n = 8). Implementation strategies targeted educational and training activities (n = 12), and less often, mechanisms of iterative improvement (n = 3). At the level of organizational design and governance, interventions mobilised users and communities through representation, at boards and committees, and through consultancy, along different phases of the design process (n = 11).

CONCLUSION

The data advance important lessons and considerations to take steps forward from disease-focused care to integrated care at two critical levels: design and implementation. Multidisciplinary work, continuity of care, and meaningful engagement of users seem crucial to attain care that is comprehensive and more proximal, within or cross organizations, or sectors. Promising practices are advanced at the level of design, implementation, and evaluation, that set integration as a continued process of improvement and value professionals and users' knowledge as assets along those phases.

Healthcare utilization among persons living with HIV in Manitoba, Canada, prior to HIV diagnosis: A case-control analysis

BACKGROUND

Understanding care patterns of persons living with HIV prior to diagnosis can inform prevention opportunities, earlier diagnosis, and engagement strategies. We examined healthcare utilization among HIV-positive individuals and compared them to HIV-negative controls.

METHODS

Data were from a retrospective cohort from Manitoba, Canada. Participants included individuals living with HIV presenting to care between 2007 and 2011, and HIV-negative controls, matched (1:5) by age, sex, and region. Data from population-based administrative databases included physician visits, hospitalizations, drug dispensation, and chlamydia and gonorrhea testing. Diagnoses associated with physician visits were classified according to International Classification of Diseases chapters. Conditional logistic regression models were used to compare cases/controls, with adjusted odds ratios (AORs) and their 95% confidence intervals (95% CI) reported.

RESULTS

A total of 193 cases and 965 controls were included. Physician visits and hospitalizations were higher for cases, compared to controls. In the 2 years prior to case date, cases were more likely to be diagnosed with "blood disorders" (AOR: 4.2, 95% CI: 2.0-9.0), be treated for mood disorders (AOR: 2.4, 95% CI: 1.6-3.4), and to have 1+ visits to a hospital (AOR: 2.2, 95% CI: 1.4-3.6).

CONCLUSION

Opportunities exist for prevention, screening, and earlier diagnosis. There is a need for better integration of healthcare services with public health.

Feasibility of implementing a same-day electronic screening tool for clinical assessment to measure patient-reported outcomes for eliciting actionable information on adherence to HIV medication and related factors in a busy Canadian urban HIV clinic

BACKGROUND

An optimal adherence to antiretroviral therapy (ART) is fundamental for suppression of HIV viral load and favourable treatment outcomes. Patient-reported outcomes (PROs) are effective tools for improving patient-provider communication and focusing providers' awareness on current health problems. The objectives of this analysis were (1) to determine the feasibility of implementing an electronic screening tool to measure PROs in a Canadian HIV clinic to obtain information on ART adherence and related factors and (2) to determine the factors related to sub-optimal adherence.

METHODS

This implementation research with a convenience sample of 600 people living with HIV (PLWH) was conducted in a busy, academic, urban HIV clinic in Toronto, Canada. PLWH were approached to participate in PRO assessments just prior to their in-clinic appointments, including health-related domains such as mental health, housing, nutrition, financial stress and medication adherence, and responses were summarized on a single sheet available for providers to review. Feasibility of implementing PROs was assessed by quantifying response rate, completion rate, time taken and participation rate. Medication adherence was elicited by self-report of the percentage of prescribed HIV medications taken in the last month. Unadjusted and adjusted odds ratios were estimated from logistic regression models to identify factors associated with adherence of <95%.

RESULTS

Of the 748 PLWH invited to participate, 692 (participation rate: 92.5%) completed the PRO assessments as standard of care in clinic. Of these, 600 consented to the use of their PRO results for research and were included in this analysis. The average response rate to the ART-related questions was 96.8% and mean completion rate was 95.5%. The median time taken to complete the assessment was 12.0 (IQR = 8.4-17.3) min, adjusted 8.7 (IQR = 7.2-10.8) min. 445 (74.9%) of participants were male, and 153 (26.2%) reported dissatisfaction with ART. 105 (19.7%) of the PLWH reported ART adherence of <95%. Multivariable logistic regression identified the following risk factors for sub-optimal adherence: dissatisfaction with ART (OR = 2.30, 95% CI 1.38-3.83), not having a family doctor or not visiting a family doctor in last year (OR = 1.69, 95% CI 1.02-2.79).

CONCLUSION

Collecting self-reported health information from PLWH through PROs in a busy urban clinic was feasible and can provide relevant information to healthcare providers on issues related to adherence. This has a potential to help in individualizing ambulatory care.

Mental Health Screening Practices Among Primary Care Providers in High HIV Burden Areas of the South: Does Having Patients with HIV Matter?

Mental health (MH) disorders are associated with HIV-related risk and health outcomes. Primary care providers (PCPs) conducting MH screenings can link persons living with HIV (PWH) to appropriate services, particularly in HIV burden areas of Southeastern States (the South). Little data exist on PCPs' MH screening practices. Depression, MH history, and substance use screenings among PCPs were examined in the South. Rao-Scott chi-square (χ²[df]) statistics (p ≤ 0.05) analyzed MH screening between PCPs with and without PWH patients. Compared with PCPs without PWH patients, PCPs with PWH patients routinely screened for substance use more frequently (50.6% vs. 43.2%; χ²[1] = 20.3; p < 0.0001). Compared with PCPs without PWH patients, PCPs with PWH patients routinely screened for depression less frequently (36.2% vs. 50.9%; χ²[1] = 32.0; p < 0.0001). Providers increasing MH screenings will improve HIV-related outcomes in the South.

Evolving Toward Shared HIV Care Using the Champlain BASE eConsult Service

Background. Electronic consultation (eConsultation) is a potential strategy to improve access to specialist expertise and facilitate collaborative care models. The Champlain BASE eConsult service allows for asynchronous communication between primary care providers (PCP) and specialists on a secure, web-based system. HIV experts accessible include HIV physician specialists, HIV pharmacists, and social workers with expertise in HIV. Objective. This study aims to describe the use, value, and utility of this eConsultation service in the care of people living with HIV and to characterize the common question types and clinical topics asked by PCPs. Methods. We analyzed the data from eConsults sent to the HIV specialty group in Ontario’s Champlain Local Health Integration Network between February 2015 and December 2017. Usage data and close-out survey responses were analyzed using descriptive statistics, eConsults were classified using a predefined list of validated taxonomy, and a thematic analysis was performed on the consultation logs to identify common clinical themes. Results. Among the 46 eConsults, the most common question type related to drug treatment (58.7%, n = 27) and management (19.6%, n = 9). The main clinical themes involved the care of significant complexities in people living with HIV, such as comorbidities and drug interactions, and suggestions of coordinated patient care. As well, eConsult was used for advice regarding pre-exposure prophylaxis for HIV-negative patients at risk of HIV infection. PCPs highly valued the eConsult service (average rating 4.8/5). Conclusion. Overall, this study demonstrates that eConsult provides an efficient and valuable service to PCPs caring for patients living with or at risk for HIV by improving access to HIV specialists and facilitating the delivery of team-based comprehensive care.

A study of outpatient healthcare use by ageing people with HIV

BACKGROUND

Antiretroviral treatment has turned HIV infection into a chronic condition with a near normal life expectancy and an ageing patient population. For a well-defined proportion of these patients, HIV-care could pass from specialty care to primary care, especially for prevention and treatment of additional chronic diseases. A better understanding of the complex health needs of this particular proportion is needed to determine the optimal way to integrate specialist and primary care.

OBJECTIVES

Our objective was to examine the health-seeking behaviour of ageing HIV patients. We investigated which physicians they consulted and the reasons for encounter. We also explored patients' participation in preventive healthcare activities.

METHODS

We conducted a retrospective descriptive cohort study among adults, 60 years of age or older living with HIV, who came for a routine consultation visit at the HIV clinic of the Institute of Tropical Medicine (ITM) over a period of 9 months. Those who met the inclusion criteria were offered a self-administered questionnaire. The responses were manually coded, exported into Excel and subsequently imported into SPSS for descriptive statistical analysis.

RESULTS

We analysed questionnaires from 74 patients, 11 women and 63 men. Since their last consultation visit at the ITM, 48 patients consulted their general practitioner (GP), 35 patients consulted a specialist and 7 went to the emergency department over a period of 6 months. Forty-nine patients (66%) had done a faecal occult blood test and 8 women (73% of female patients) had a screening mammography in the past 2 years, 8 women (73% of female patients) had a PAP smear in the past 3 years. Sixty-three participants (85%) declared that their vaccinations were up-to-date. Thirty-eight patients (51%) take antihypertensive medication, 35 patients (47%) cholesterol medication and 9 participants (12%) are on oral antihyperglycemic medication.

CONCLUSIONS

A large proportion of patients are seeking healthcare from their GP and specialists, other than the HIV specialist. They do so both for curative and preventive health needs. This calls for a more structured collaboration between the various care providers, whereby communication plays a pivotal role.

Physicians' patient base composition and mortality among people living with HIV who initiated antiretroviral therapy in a universal care setting

OBJECTIVES

To assess the impact of physicians' patient base composition on all-cause mortality among people living with HIV (PLHIV) who initiated highly active antiretroviral therapy (HAART) in British Columbia (BC), Canada.

DESIGN

Observational cohort study from 1 January 2000 to 31 December 2013.

SETTING

BC Centre for Excellence in HIV/AIDS' (BC-CfE) Drug Treatment Program, where HAART is available at no cost.

PARTICIPANTS

PLHIV aged ≥ 19 who initiated HAART in BC in the HAART Observational Medical Evaluation and Research (HOMER) Study.

OUTCOME MEASURES

All-cause mortality as determined through monthly linkages to the BC Vital Statistics Agency.

STATISTICAL ANALYSIS

We examined the relationships between patient characteristics, physicians' patient base composition, the location of the practice, and physicians' experience with PLHIV and all-cause mortality using unadjusted and adjusted Cox proportional hazards models.

RESULTS

A total of 4 445 PLHIV (median age = 42, Q1, Q3 = 34-49; 80% male) were eligible for our study. Patients were seen by 683 prescribing physicians with a median experience of 77 previously treated PLHIV in the past 2 years (Q1, Q3 = 23-170). A multivariable Cox model indicated that the following factors were associated with all-cause mortality: age (aHR = 1.05 per 1-year increase, 95% CI = 1.04 to 1.06), year of HAART initiation (2004-2007: aHR = 0.65, 95% CI = 0.53 to 0.81, 2008-2011: aHR = 0.46, 95% CI = 0.35 to 0.61, Ref: 2000-2003), CD4 cell count at baseline (aHR = 0.88 per 100-unit increase in cells/mm³, 95% CI = 0.82 to 0.94), and < 95% adherence in first year on HAART (aHR = 2.28, 95% CI = 1.88 to 2.76). In addition, physicians' patient base composition, specifically, the proportion of patients who have a history of injection drug use (aHR = 1.11 per 10% increase in the proportion of patients, 95% CI = 1.07 to 1.15) or Indigenous ancestry (aHR = 1.07 per 10% increase , 95% CI = 1.03-1.11) and being a patient of a physician who primarily serves individuals outside of the Vancouver Coastal Health Authority region (aHR = 1.22, 95% CI = 1.01 to 1.47) were associated with mortality.

CONCLUSIONS

Our findings suggest that physicians with a higher proportion of individuals who face potential barriers to care may need additional supports to decrease mortality among their patients. Future research is required to examine these relationships in other settings and to determine strategies that may mitigate the associations between the composition of physicians' patient bases and survival.

The prevalence and characteristics of HIV/AIDS patients presenting at a chiropractic outpatient clinic in Toronto, Ontario. A retrospective, observational study

OBJECTIVE

To determine the prevalence and presenting complaints of HIV/AIDS patients attending a chiropractic outpatient teaching clinic in downtown Toronto, and explore their self-reported comorbidities, medications used, and consumption of other complementary health care.

METHODS

A random sample was drawn from the entire clinic file collection spanning the years 2007 to 2013. Files were anonymized and coded to ensure confidentiality.

RESULTS

A total of 264 files were radomly pulled from approxinately 3750 clinic files. The prevalence of HIV positive patients was 5.7% (15/264), predominantly males, with 3 patients having developed AIDS. Co-infection with Hepatitis B and/or C was identified in 5/15 patients. The most common presenting complaint was neck pain (80%), followed by low back pain (47%) compared to 20% and 43% respectively for the general cohort. Eleven of 15 patients were on antiretroviral treatment (ART); The frequency of comorbidities was 8/15 (53%) however, none were identified as being dominant. In addition to chiropractic, 7/15 patients reported receiving other complementary therapies.

CONCLUSIONS

A relatively small proportion of HIV/ AIDS patients were found to be receiving treatments in this downtown chiropractic clinic situated within a community health clinic setting. The principal presenting complaint was neck pain.

Long-term HIV/AIDS survivors: Patients living with HIV infection retained in care for over 20 years. What have we learned?

Individuals diagnosed with HIV before 1996 had poor prognoses. Few HIV care centers can track patients continuously from the 1980s to present. We determined the sociodemographic, clinical, and health care utilization characteristics of patients diagnosed and followed for >20 years (i.e. long-term HIV/AIDS survivors) to understand what factors contributed to survival. All HIV-positive patients diagnosed before 1996 were categorized as active, moved/lost, or died as of 1 January 2016. Baseline sociodemographic, clinical characteristics, antiretroviral therapy (ART) usage, retention, HIV care costs, and health status were analyzed. Of 876 patients, 49.5% died, 30.3% moved or left, 20.3% remained active in care for a median of 23.4 years. At diagnosis, continuously-followed patients were younger with a higher CD4 cell count, attended regular clinic visits at higher frequencies, and had received more ART than patients who moved or died. As of 1 January 2016, their median age was 57 years (interquartile range 53-62), 15% were aged >65 years, median CD4 cell count was 591 cells/mm³ (475-863) with 68% >500 cells/mm³. Sixty-two percent remained employed. The total cost of HIV care was $32,251,030 (Cdn$); median cost per patient per year $15,418 ($13,697-$18,392). Individuals diagnosed prior to 1996 benefited from early diagnosis and engagement to care, regular follow-ups, and timely initiation of ART, strongly supporting the modern guidelines of care.

The organizational attributes of HIV care delivery models in Canada: A cross-sectional study

HIV treatment in Canada has rapidly progressed with the advent of new drug therapies and approaches to care. With this evolution, there is increasing interest in Canada in understanding the current delivery of HIV care, specifically where care is delivered, how, and by whom, to inform the design of care models required to meet the evolving needs of the population. We conducted a cross-sectional survey of Canadian care settings identified as delivering HIV care between June 2015 and January 2016. Given known potential differences in delivery approaches, we stratified settings as primary care or specialist settings, and described their structure, geographic location, populations served, health human resources, technological resources, and available clinical services. We received responses from 22 of 43 contacted care settings located in seven Canadian provinces (51.2% response rate). The total number of patients and HIV patients served by the participating settings was 38,060 and 17,678, respectively (mean number of HIV patients in primary care settings = 1,005, mean number of HIV patients in specialist care settings = 562). Settings were urban for 20 of the 22 (90.9%) clinics and 14 (63.6%) were entirely HIV focused. Primary care settings were more likely to offer preventative services (e.g., cervical smear, needle exchange, IUD insertion, chronic disease self-management program) than specialist settings. The study illustrates diversity in Canadian HIV care settings. All settings were team based, but primary care settings offered a broader range of preventative services and comprehensive access to mental health services, including addictions and peer support.

A cross-sectional population-based study of breast cancer screening among women with HIV in Ontario, Canada

BACKGROUND

As women with HIV live longer, the need for age-appropriate breast cancer screening will increase. We compared rates of screening mammography among women with and without HIV.

METHODS

We used administrative health databases to identify all women in Ontario, Canada, who were eligible for screening mammography (aged 50 to 74 yr and no history of breast cancer) as of Apr. 1, 2011. We used multivariable log-binomial regression to compare the 2-year period prevalence of screening mammography in 2011 to 2013 among women with and without HIV and to examine the correlates of screening among women with HIV.

RESULTS

We identified 1 447 015 screen-eligible women, among whom 623 (0.04%) were women with HIV. Women with HIV were less likely to undergo screening than women without HIV (50.1% v. 63.4%, p < 0.001). Following multivariable adjustment, HIV-positive status was associated with significantly lower odds of undergoing mammography (adjusted prevalence ratio [PR] 0.83, 95% confidence interval [CI] 0.77-0.89). Compared with women with HIV receiving regular care from both a family physician and an HIV specialist, women with HIV receiving neither kind of care (adjusted PR 0.64, 95% CI 0.50-0.83) or predominantly specialist care (adjusted PR 0.77; 95% CI 0.60 to 0.97) were less likely to undergo screening mammography.

INTERPRETATION

Women with HIV are less likely to undergo breast cancer screening mammography than women without HIV. Addressing this disparity requires optimizing care delivery to ensure adequate provision of comprehensive primary care to people with HIV.

Human Immunodeficiency Virus (HIV) Quality Indicators Are Similar Across HIV Care Delivery Models

BACKGROUND

There are limited data on human immunodeficiency virus (HIV) quality indicators according to model of HIV care delivery. Comparing HIV quality indicators by HIV care model could help inform best practices because patients achieving higher levels of quality indicators may have a mortality benefit.

METHODS

Using the Partners HIV Cohort, we categorized 1565 patients into 3 HIV care models: infectious disease provider only (ID), generalist only (generalist), or infectious disease provider and generalist (ID plus generalist). We examined 12 HIV quality indicators used by 5 major medical and quality associations and grouped them into 4 domains: process, screening, immunization, and HIV management. We used generalized estimating equations to account for most common provider and multivariable analyses adjusted for prespecified covariates to compare composite rates of HIV quality indicator completion.

RESULTS

We found significant differences between HIV care models, with the ID plus generalists group achieving significantly higher quality measures than the ID group in HIV management (94.4% vs 91.7%, P = .03) and higher quality measures than generalists in immunization (87.8% vs 80.6%, P = .03) in multivariable adjusted analyses. All models achieved rates that equaled or surpassed previously reported quality indicator rates. The absolute differences between groups were small and ranged from 2% to 7%.

CONCLUSIONS

Our results suggest that multiple HIV care models are effective with respect to HIV quality metrics. Factors to consider when determining HIV care model include healthcare setting, feasibility, and physician and patient preference.

Non-Communicable Disease Preventive Screening by HIV Care Model

Importance

The Human Immunodeficiency Virus (HIV) epidemic has evolved, with an increasing non-communicable disease (NCD) burden emerging and need for long-term management, yet there are limited data to help delineate the optimal care model to screen for NCDs for this patient population.

Objective

The primary aim was to compare rates of NCD preventive screening in persons living with HIV/AIDS (PLWHA) by type of HIV care model, focusing on metabolic/cardiovascular disease (CVD) and cancer screening. We hypothesized that primary care models that included generalists would have higher preventive screening rates.

Design

Prospective observational cohort study.

Setting

Partners HealthCare System (PHS) encompassing Brigham & Women’s Hospital, Massachusetts General Hospital, and affiliated community health centers.

Participants

PLWHA age >18 engaged in active primary care at PHS.

Exposure

HIV care model categorized as infectious disease (ID) providers only, generalist providers only, or ID plus generalist providers.

Main Outcome(s) and Measures(s)

Odds of screening for metabolic/CVD outcomes including hypertension (HTN), obesity, hyperlipidemia (HL), and diabetes (DM) and cancer including colorectal cancer (CRC), cervical cancer, and breast cancer.

Results

In a cohort of 1565 PLWHA, distribution by HIV care model was 875 ID (56%), 90 generalists (6%), and 600 ID plus generalists (38%). Patients in the generalist group had lower odds of viral suppression but similar CD4 counts and ART exposure as compared with ID and ID plus generalist groups. In analyses adjusting for sociodemographic and clinical covariates and clustering within provider, there were no significant differences in metabolic/CVD or cancer screening rates among the three HIV care models.

Conclusions

There were no notable differences in metabolic/CVD or cancer screening rates by HIV care model after adjusting for sociodemographic and clinical factors. These findings suggest that HIV patients receive similar preventive health care for NCDs independent of HIV care model.
