The Comparative Outcomes and Service Utilization Trends (COAST) study compares health outcomes among People With HIV (PWH) Without (PWoH) in British Columbia (BC), Canada. cohort was recently updated to include persons diagnosed with after March 31, 2013, expanded broaden research applications. COAST includes PWH a 10% random sample of the general population without HIV, all aged ≥19. Our links an registry healthcare practitioner billing, hospital emergency department attendance data,...
Abstract We estimated the degree to which language used in high-profile medical/public health/epidemiology literature implied causality using linking exposures outcomes and action recommendations; examined disconnects between identified most common phrases; how strongly phrases imply causality. searched for screened 1,170 articles from 18 journals (65 per journal) published 2010–2019. Based on written framing systematic guidance, 3 reviewers rated of abstracts full text exposure/outcome...
Objectives As people living with HIV (PLWH) live longer, morbidity and mortality from non-AIDS comorbidities have emerged as major concerns. Our objective was to compare prevalence trends age at diagnosis of nine chronic age-associated between individuals without HIV. Design setting This population-based cohort study used longitudinal data all diagnosed antiretroviral-treated PLWH 1:4 age-sex-matched HIV-negative in British Columbia, Canada. Participants The included 8031 32 124 controls...
People living with HIV (PLWH) in Canada experience high rates of interpersonal violence which may lead to adverse health outcomes that require hospitalization. Using self-reported data on experiences linked administrative hospitalizations, we used Poisson regression modelling examine and compare the associations between (recent [in past 6 months], non-recent [>6 months ago], or none) hospitalization rates, among a sample PLWH British Columbia, Canada. Of 984 included this study, 60.0%...
Objective: We characterized sociodemographic and behavioural factors associated with mortality among people living HIV (PLWH) in British Columbia (BC), Canada. Design: used purposive sampling to recruit a representative cohort of PLWH aged ≥19 years from January 2016-September 2018. Participants completed survey consented link their data the BC Vital Statistics Agency, where deaths were recorded. Methods: conducted bivariate analyses compare characteristics between participants who died...
While research has begun addressing food insecurity (FI) in HIV-positive populations, knowledge regarding FI among individuals living with HIV-hepatitis C virus (HCV) co-infection is limited. This exploratory study examines sociodemographic, socioeconomic, behavioral, and clinical factors associated a cohort of HIV-HCV co-infected Canada. We analyzed longitudinal data from the Food Security Co-infection Study Canadian Cohort collected between November 2012-June 2014 at 15 health centres. was...
Abstract Background We described the impact of different lengths lookback window (LW), a retrospective time period to observe diagnoses in administrative data, on prevalence and incidence eight chronic diseases. Methods Our study populations included people living with HIV ( N = 5151) 1:5 age-sex-matched HIV-negative individuals 25,755) British Columbia, Canada, complete follow-up between 1996 2012. measured diseases 2012 using LWs ranging from 1 16 years. Cases were deemed prevalent if...
Due to stigma and discrimination, gay, bisexual other men who have sex with (gbMSM) potentially carry a heightened burden of loneliness. This analysis investigates loneliness among gbMSM its relationship self-rated physical health, along the mediating effect depression.
To examine the independent association between intimate partner violence (IPV) severity and all-cause mortality among women living with HIV (WLHIV).Cross-sectional questionnaire linked to longitudinal vital statistics data.We examined lifetime prevalence of IPV age-standardized rates by reported WLHIV. Lifetime (emotional/verbal, physical, or sexual) was assessed as a categorical variable: no history any (none); experienced one two forms (moderate); all three (severe IPV). Two separate...
Routinely collected health data (RCD) including electronic records, disease registries, administrative and wearables are not specifically for research purposes. Analysis of these poses unique methodological challenges that must be addressed when conducting research, particularly as availability use increase. This scoping review aimed to identify in using RCD from existing literature (registered protocol: https://doi.org/10.17605/OSF.IO/EBM4D). We searched 6 databases, medical, economics,...
BackgroundHospitalizations are a resource-intensive form of healthcare use, particularly for persons with chronic conditions such as those HIV. Interhospital transfers typically appear separate records in Canadian databases; misclassifying independent hospitalizations can bias key metrics readmission rates. We examined approaches combining sequential, related into hospitalization episodes care (HEoCs) among and without HIV (PWH; PWoH) British Columbia (BC), Canada. MethodsBC (1992 to 2020)...
Objectives The aim of this study was to determine the impact food insecurity (FI) on HIV viral load and CD4 count among people coinfected with hepatitis C virus (HCV). Methods This conducted using data from Food Security & HIV‐HCV Sub‐Study Canadian Co‐Infection Cohort study. FI measured adult scale Health Canada's Household Survey Module classified into three categories: security, moderate severe insecurity. association between FI, load, assessed a stabilized inverse probability...
Objective: To identify potential pathways by which a variety of factors act to lead unsuppressed viral load. Design: A prospective cohort HIV–HCV co-infected adults receiving care from 18 HIV clinics across Canada was followed every 6 months between November 2012 and October 2015. Participants with at least two visits while combined antiretroviral treatment (cART) were included. Methods: path analysis conducted on the basis ordered sequences multivariate logistic regressions using...
Nontyphoidal Salmonella spp. are one of the most common causes bacterial foodborne illness. Variability in cost inventories and study methodologies limits possibility meaningfully interpreting comparing cost-of-illness (COI) estimates, reducing their usefulness. However, little is known about relative effect these factors have on a estimate. This important for existing estimates when designing new studies. Cost-of-illness identified through scoping review, were used to investigate...
Abstract Objective: Food insecurity, or self-reports of inadequate food access due to limited financial resources, remains prevalent among people living with HIV (PLHIV). We examined the impact insecurity on combination antiretroviral therapy (cART) adherence within an integrated care programme that provides services PLHIV, including two meals per day. Design: Adjusted OR (aOR) were estimated by generalized estimating equations, quantifying relationship between (exposure) and cART (outcome)...
Our study aims to define and identify correlates of social isolation among people living with HIV (PLHIV). The Longitudinal Investigation into Supportive Ancillary health services (LISA) provided a cross-sectional analytic sample 996 PLHIV in British Columbia, Canada (sampled between 2007 2010). Individuals marginalized by socio-structural inequities were oversampled; sampling bias was addressed through inverse probability participation weighting. Through latent class analysis, three groups...
Injection drug use (IDU) and food insecurity (FI) are highly prevalent among individuals living with HIV-hepatitis C virus (HCV) co-infection. We quantified the association between IDU FI co-infected using biannual data from Canadian Co-infection Cohort (N = 608, 2012–2015). (in past six months) frequency (non-weekly/weekly in month) were self-reported. severity (marginal FI, moderate severe FI) measured Household Food Security Survey Module. Generalized estimating equations used to estimate...
Introduction Case-finding algorithms can be applied to administrative healthcare records identify people with diseases, including HIV (PWH). When supplementing an existing registry of a low prevalence disease, near-perfect specificity helps minimize impacts adding in algorithm-identified false positive cases. We evaluated the performance supplement British Columbia (BC), Canada. Methods based on HIV-related diagnostic codes practitioner and hospitalization records. 28 validation sub-sample...
