Psychosocial and structural factors and changes in quality of life measures among people living with HIV in British Columbia, Canada
We examined determinants of quality of life (QoL) at enrollment and over time among people living with HIV(PLWH) aged ≥19 years in British Columbia, Canada, between January 2016-September 2021. The participants completed the surveys at enrollment, 18 and 36 months. QoL was measured using the Short-Form Six-Dimension Scale, social support using the Medical Outcome Study Social Support Survey, and depressive symptoms using the Center for Epidemiolo…
Healthcare Provider Strategies and Approaches to Supporting People Living With HIV Who Are Experiencing HIV Treatment Disengagement in British Columbia, Canada
We conducted a strengths-based, qualitative study to elucidate the approaches and strategies utilized by healthcare providers (HCPs) to support HIV treatment engagement in British Columbia (BC), Canada. Healthcare providers (e.g., nurses, peer navigators, and pharmacists) across the province of BC were recruited through regional HIV programs and by word of mouth through purposive sampling strategies. An academic and community researcher co-conduc…
Dynamics of overdose and non-overdose mortality among people living with HIV amidst the illicit drug toxicity crisis in British Columbia
We sought to characterize overdose and non-overdose mortality among PLWH amidst the illicit drug toxicity crisis in British Columbia, Canada. A population-based analysis of PLWH (age ≥19) in British Columbia accessing healthcare from April 1996 to March 2017 was conducted using data from the Seek and Treat for Optimal Prevention of HIV/AIDS (STOP HIV/AIDS) cohort linkage. Underlying causes of deaths were stratified into overdose and non-overdose …
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…
Retention in primary care among unstably housed residents of a low-income, inner-city neighborhood with a high prevalence of substance use and related disorders
We found that a primary healthcare model of care was successful in retaining over two-thirds of clients in primary healthcare after more than 18 months of follow-up. Additional supports for those diagnosed with alcohol use disorder are needed to retain them in care
The impact of the Covid-19 pandemic on HIV treatment gap lengths and viremia among people living with HIV British Columbia, Canada, during the Covid-19 pandemic
The SARS-CoV-2 (COVID-19) pandemic has impacted the care of people living with HIV (PLWH). This study aims to characterize the impact of the pandemic on the length of HIV treatment gap lengths and viral loads among people living with HIV (PLWH) in British Columbia (BC), Canada, with a focus on Downtown Eastside (DTES), which is one of the most impoverished neighbourhoods in Canada. We analyzed data from the HIV/AIDS Drug Treatment Program from Ja…
It’s all about connection
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
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
Exploring Primary Healthcare Experiences and Interest in Mobile Technology Engagement Amongst an Urban Population Experiencing Barriers to Care
Mobile phone-based engagement approaches provide potential platforms for improving access to primary healthcare (PHC) services for underserved populations. We held two focus groups (February 2020) with residents ( n = 25) from a low-income urban neighbourhood (downtown Vancouver, Canada), to assess recent healthcare experiences and elicit interest in mobile phone-based healthcare engagement for underserved residents. Note-based analysis, guided b…
Healthcare and treatment experiences among people diagnosed with HIV before and after a province-wide treatment as prevention initiative in British Columbia, Canada
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
Periods of Homelessness Linked to Higher Vacs Index Among HIV-Positive People Who Use Drugs
Migration Patterns from an Open Illicit Drug Scene and Emergency Department Visits among People Who Use Illicit Drugs in Vancouver, Canada
BACKGROUND: People who use illicit drugs (PWUD) experience various adverse health outcomes leading to increased healthcare service utilization. PWUD are also a highly mobile population which poses challenges to healthcare delivery. The objective of this study was to identify migration patterns from the Downtown Eastside (DTES), an urban illicit drug scene in Vancouver and to estimate the impact of different migration patterns on two outcomes: a) …
Characteristics of older adults living with HIV accessing home and community care services in British Columbia, Canada
Over half of people living with HIV (PLHIV) engaged in care in British Columbia (BC) are age ≥50. The public home and community care (HCC) system offers formal support that PLHIV may turn to as they age, but little is known about access specific to PLHIV. Using data from the STOP HIV/AIDS cohort, which includes linked treatment and demographic records for PLHIV accessing care in BC, we compared older PLHIV (defined as those age ≥50) who did and d…
The opioid crisis is driving mortality among under-served people living with HIV in British Columbia, Canada
Overdose is - the leading cause of mortality among a cohort of under-served PLWH in BC, Canada. Public health efforts to end the HIV epidemic and support the health and well-being of PLWH are being thwarted by persistent health inequities and the enormous and persistent risks facing people who use drugs. Integrated low-barrier primary care is essential for supporting under-served PLWH, and safe drug supply is needed to support PLWH who use drugs
Overdose mortality is reducing the gains in life expectancy of antiretroviral-treated people living with HIV in British Columbia, Canada
Impact of migration from an illicit drug scene on hospital outcomes among people who use illicit drugs in Vancouver, Canada
Behavioural, social and structural-level risk factors for developing Aids among HIV-positive people who use injection drugs in a Canadian setting, 1996–2017
People who use injection drugs (PWID) experience high rates of HIV acquisition and, as a result of lower rates of optimal access and adherence to combination antiretroviral therapy (ART), experience worse HIV treatment outcomes than other key affected populations. However, the incidence and risk factors for the development of AIDS among HIV-positive PWID have not been completely described. We used data from a community-recruited prospective cohor…
