Evaluating experiences of HIV-related stigma among people living with HIV diagnosed in different treatment eras in British Columbia, Canada.

There is mixed evidence on whether experiences of HIV-related stigma are mitigated with lived experience. We sought to examine whether people living with HIV (PLWH) with longer living experience reported varying levels of HIV-related stigma. Between January 2016-September 2018, we used purposive sampling to enrol PLWH aged ≥19 across British Columbia, Canada, where participants completed the 10-item Berger HIV Stigma Scale. We conducted bivariate analyzes examining key sociodemographic characteristics and HIV-related stigma scores. Multivariable linear regression modelled the association between year of HIV diagnosis by treatment era and HIV-related stigma scores. We enrolled 644 participants; median age at enrolment was 50 years (Q1-Q3: 42-56), with 37.4% (n = 241) diagnosed before the year 2000. The median HIV-stigma scores of all participants (19.0, Q1-Q3: 13-25, range 0-40) stratified by treatment era were: 17.0 (pre-1996), 20.0 (1996-1999), 20.0 (2000-2009), 19.0 (2010-2018) (p = 0.03). While there was a significant association at the univariate level, year of HIV diagnosis by treatment era was not associated with stigma scores after controlling for age, gender, HIV key populations, ethnicity, relationship status, social support, and ever having a mental health disorder diagnosis. This suggests that PLWH still experience HIV-related stigma today, compared to those diagnosed in earlier time periods.

Depressive Symptoms, the Impact on ART Continuation, and Factors Associated with Symptom Improvement Among a Cohort of People Living with HIV in British Columbia, Canada.

Depressive symptoms among people living with HIV (PLWH) are associated with poorer overall health outcomes. We characterized depressive symptoms and improvements in symptomology among PLWH (≥ 19 years old) in British Columbia (BC), Canada. We also examined associations between depressive symptomology and antiretroviral therapy (ART) treatment interruptions. Depressive symptoms were measured using the 10-item Center for Epidemiologic Studies Depression Scale (CES-D-10), within a longitudinal cohort study with three surveys administered 18-months apart. We used multivariable logistic regression to model factors associated with improvements in depressive symptoms (CES-D-10 scores from ≥ 10 to < 10). Of the 566 participants eligible for analysis 273 (48.2%) had CES-D scores indicating significant depressive symptoms (score ≥ 10) at enrollment. Improvements in symptoms at first follow-up were associated with greater HIV self-care on the Continuity of Care Scale (adjusted odds ratio: 1.17; 95% CI 1.03-1.32), and not having a previously reported mental health disorder diagnosis (aOR 2.86; 95% CI 1.01-8.13). Those reporting current cocaine use (aOR 0.33; 95% CI 0.12-0.91) and having a high school education, vs. less than, (aOR 0.25; 95% CI 0.08-0.82) had lower odds of improvement in depressive symptomatology. CES-D scores ≥ 10 were not significantly associated with ART treatment interruptions during follow-up (aOR: 1.08; 95% CI:0.65-1.8). Supporting greater self-care and consideration of mental health management strategies in relation to HIV may be useful in promoting the wellbeing of PLWH who experience depressive symptoms.

It's all about connection: Determinants of social support and the influence on HIV treatment interruptions among people living with HIV in British Columbia, Canada.

BACKGROUND: Social support has previously been found to be associated with improved health outcomes of individuals managing chronic illnesses, including amongst people living with HIV (PLWH). For women and people who use injection drugs who continue to experience treatment disparities in comparison to other PLWH, social support may have potential in facilitating better treatment engagement and retention. In this analysis, we examined determinants of social support as measured by the Medical Outcomes Study - Social Support Survey (MOS-SSS) scale, and quantified the relationship between MOS-SSS and HIV treatment interruptions (TIs) among PLWH in British Columbia, Canada. METHODS: Between January 2016 and September 2018, we used purposive sampling to enroll PLWH, 19 years of age or older living in British Columbia into the STOP HIV/AIDS Program Evaluation study. Participants completed a baseline survey at enrolment which included the MOS-SSS scale, where higher MOS-SSS scores indicated greater social support. Multivariable linear regression modeled the association between key explanatory variables and MOS-SSS scores, whereas multivariable logistic regression modeled the association between MOS-SSS scores and experiencing TIs while controlling for confounders. RESULTS: Among 644 PLWH, we found that having a history of injection drug use more than 12 months ago but not within the last 12 months, self-identifying as Indigenous, and sexual activity in the last 12 months were positively associated with MOS-SSS, while being single, divorced, or dating (vs. married), experiences of lifetime violence, and diagnosis of a mental health disorder were inversely associated. In a separate multivariable model adjusted for gender, ethnicity, recent homelessness, sexual activity in the last 12 months, and recent injection drug use, we found that higher MOS-SSS scores, indicating more social support, were associated with a lower likelihood of HIV treatment interruptions (adjusted odds ratio: 0.90 per 10-unit increase, 95% confidence interval: 0.83, 0.99). CONCLUSIONS: Social support may be an important protective factor in ensuring HIV treatment continuity among PLWH. Future research should examine effective means to build social support among communities that have potential to promote increased treatment engagement.

Healthcare and treatment experiences among people diagnosed with HIV before and after a province-wide treatment as prevention initiative in British Columbia, Canada.

INTRODUCTION: In 2010, the Canadian province of British Columbia (BC) initiated the Seek and Treat for Optimal Prevention of HIV/AIDS (STOP HIV/AIDS) program to improve HIV testing, linkage to care, and treatment uptake, thereby operationalizing the HIV Treatment as Prevention (TasP) framework at the population-level. In this analysis, we evaluated self-reported HIV care experiences and therapeutic outcomes among people diagnosed with HIV prior to and after implementation of this provincial program. METHODS: A cross-sectional analysis was performed on the baseline data of a cohort of people living with HIV (PLWH) (19 years and older) in the province of BC sampled from July 2016 to September 2018. All participants consented to linking their survey data to the provincial HIV treatment registry. Individuals diagnosed with HIV from January 1 2000-December 31 2009 were classified as pre-intervention and those diagnosed January 1 2010-December 31 2018 as post-intervention cohorts. Bivariate analyses were run using Chi-square and Wilcoxon Rank Sum tests. Cox proportional hazards regression model demonstrates time to antiretroviral therapy (ART) initiation (from HIV baseline) and virological suppression (2 consecutive plasma viral load measurements < 200 copies/ml). RESULTS: Of the 325 participants included in this analysis, 198 (61%) were diagnosed with HIV in the pre-intervention era and 127 (39%) in the post-intervention era. A higher proportion of participants in post-intervention era were diagnosed at walk-in clinics (45% vs. 39%) and hospitals (21% vs. 11%) (vs pre-intervention) (p = 0.042). Post-intervention participants had initiated ART with less advanced HIV disease (CD4 count 410 vs. 270 cells/ul; p = 0.001) and were less likely to experience treatment interruptions at any point in the 5 years after HIV diagnosis (17% vs. 48%; p < 0.001). The post-intervention cohort had significantly more timely ART initiation (aHR: 5.97, 95%CI 4.47, 7.97) and virologic suppression (aHR: 2.03, 95%CI 1.58, 2.60) following diagnosis, after controlling for confounders. CONCLUSIONS: We found favourable treatment experiences and more timely ART initiation and virologic suppression after a targeted TasP provincial program. Our results illustrate the importance of accessible low-barrier HIV testing and treatment in tackling the HIV epidemic.

Depressive symptoms among people living with HIV in permanent supportive housing: Findings from a community-based participatory study in Vancouver, Canada.

Permanent supportive housing (PSH) is an intervention addressing housing needs among marginally housed individuals. Little is known about whether and how PSH influences depressive symptoms among people living with HIV (PLHIV). This article shares results from a community-based study that, in 2016-2017, interviewed 24 residents of a PSH facility designated for PLHIV in Vancouver, Canada. The themes of taking control; social connectedness; conviviality; and relationships and supports described how the PSH environment affected depressive symptoms among the residents.

The "Sticky Notes" Method: Adapting Interpretive Description Methodology for Team-Based Qualitative Analysis in Community-Based Participatory Research.

Community-based participatory research (CBPR) has a long history within HIV research, yet little work has focused on facilitating team-based data analysis within CBPR. Our team adapted Thorne's interpretive description (ID) for CBPR analysis, using a color-coded "sticky notes" system to conduct data fragmentation and synthesis. Sticky notes were used to record, visualize, and communicate emerging insights over the course of 11 in-person participatory sessions. Data fragmentation strategies were employed in an iterative four-step process that was reached by consensus. During synthesis, the team created and recreated mind maps of the 969 sticky notes, from which we developed categories and themes through discussion. Flexibility, trust, and discussion were key components that facilitated the evolution of the final process. An interactive, team-based approach was central to data co-creation and capacity building, whereas the "sticky notes" system provided a framework for identifying and sorting data.

Cohort profile: the STOP HIV/AIDS Program Evaluation (SHAPE) study in British Columbia, Canada.

PURPOSE: The Seek and Treat for Optimal Prevention of HIV/AIDS (STOP HIV/AIDS) Program Evaluation (SHAPE) study is a longitudinal cohort developed to monitor the progress of an HIV testing and treatment expansion programme across the province of British Columbia (BC). The study considers how sociostructural determinants such as gender, age, sexual identity, geography, income and ethnicity influence engagement in HIV care. PARTICIPANTS: Between January 2016 and September 2018, 644 BC residents who were at least 19 years old and diagnosed with HIV were enrolled in the study and completed a baseline survey. Participants will complete two additional follow-up surveys (18 months apart) about their HIV care experiences, with clinical follow-up ongoing. FINDINGS TO DATE: Analyses on baseline data have found high levels of HIV care engagement and treatment success among SHAPE participants, with 95% of participants receiving antiretroviral therapy and 90% having achieved viral suppression. However, persistent disparities in HIV treatment outcomes related to age, injection drug use and housing stability have been identified and require further attention when delivering services to marginalised groups. FUTURE PLANS: Our research will examine how engagement in HIV care evolves over time, continuing to identify barriers and facilitators for promoting equitable access to treatment and care among people living with HIV. A qualitative research project, currently in the formative phase, will compliment quantitative analyses by taking a strengths-based approach to exploring experiences of engagement and re-engagement in HIV treatment among individuals who have experienced delayed treatment initiation or treatment interruptions.
