Implementation of risk mitigation prescribing during dual public health emergencies
Implementation and access to risk mitigation prescribing in Northern BC was limited, with region-specific applicability challenges and a health service delivery model that was not able to sufficiently meet the unique service needs of IPWUD. Demonstrating Northern ingenuity, peer groups, harm reduction community champions, and telehealth services were identified as stopgap measures that promoted access and reduced inequitable implementation within…
Just have this come from their prescription pad
Context In March 2020, British Columbia introduced the Risk Mitigation Guidance (RMG) to enable the prescription of pharmaceutical substitutes for the unregulated drug market to decrease overdose deaths and COVID-19 infections. This study presents health planners’ perspectives on the RMG adoption within a medicalized system of care.Methods We conducted interviews with 28 health planners to obtain their views on implementation. We undertook a them…
Associations of County-Level Social Determinants of Health with Covid-19 Related Hospitalization Among People with HIV
Individually, the COVID-19 and HIV pandemics have differentially impacted minoritized groups due to the role of social determinants of health (SDoH) in the U.S. Little is known how the collision of these two pandemics may have exacerbated adverse health outcomes. We evaluated county-level SDoH and associations with hospitalization after a COVID-19 diagnosis among people with (PWH) and without HIV (PWOH) by racial/ethnic groups. We used the U.S. N…
Analyzing quality of life among people with opioid use disorder from the National Institute on Drug Abuse Data Share initiative
We observed HSUVs for OUD that were higher than those from previous studies that had been conducted without input from people living with the condition
Sensitivity to change of generic preference-based instruments (EQ-5D-3L, EQ-5D-5L, and HUI3) in the context of treatment for people with prescription-type opioid use disorder in Canada
Purpose Using data from a randomized controlled trial for treatment of prescription-type opioid use disorder in Canada, this study examines sensitivity to change in three preference-based instruments [EQ-5D-3L, EQ-5D-5L, and the Health Utilities Index Mark 3 (HUI3)] and explores an oft-overlooked consideration when working with contemporaneous responses for similar questions—data quality. Methods Analyses focused on the relative abilities of thre…
Translating and disseminating a localised economic model to support implementation of the ‘Ending the HIV Epidemic’ initiative to public health policymakers
To optimise acceptance and use of results from economic models, researchers should engage with local community members and public health decision makers early to understand budgetary and community priorities. Participants prioritised evidence that supports their existing strategies, considers budgets and funding streams, and improves health equity; however, real-world budget constraints and conflicting interests serve as barriers to implementing …
Association of Opioid Agonist Treatment With All-Cause Mortality and Specific Causes of Death Among People With Opioid Dependence
Importance Mortality among people with opioid dependence is higher than that of the general population. Opioid agonist treatment (OAT) is an effective treatment for opioid dependence; however, there has not yet been a systematic review on the relationship between OAT and specific causes of mortality. Objective To estimate the association of time receiving OAT with mortality. Data Sources The Embase, MEDLINE, and PsycINFO databases were searched t…

Increased drug use and the timing of social assistance receipt among people who use illicit drugs
Expansion of Haart Coverage Is Associated with Sustained Decreases in HIV/Aids Morbidity, Mortality and HIV Transmission
BACKGROUND: There has been renewed call for the global expansion of highly active antiretroviral therapy (HAART) under the framework of HIV treatment as prevention (TasP). However, population-level sustainability of this strategy has not been characterized. METHODS: We used population-level longitudinal data from province-wide registries including plasma viral load, CD4 count, drug resistance, HAART use, HIV diagnoses, AIDS incidence, and HIV-rel…
Antiretroviral Drug Costs and Prescription Patterns in British Columbia, Canada
INTRODUCTION: Treatment options and therapeutic guidelines have evolved substantially since highly active antiretroviral treatment (HAART) became the standard of HIV care in 1996. We conducted the present population-based analysis to characterize the determinants of direct costs of HAART over time in British Columbia, Canada. METHODS: We considered individuals ever receiving HAART in British Columbia from 1996 to 2011. Linear mixed-effects regres…
Offender Diversion Into Substance Use Disorder Treatment
Objectives. We determined the costs and savings attributable to the California Substance Abuse and Crime Prevention Act (SACPA), which mandated probation or continued parole with substance abuse treatment in lieu of incarceration for adult offenders convicted of nonviolent drug offenses and probation and parole violators. Methods. We used individually linked, population-level administrative data to define intervention and control cohorts of offen…
Estimating the economic value of British Columbia's domestic cannabis market
Determinants of the Cost of Health Services Used by Veterans With HIV
BACKGROUND: The effect of adherence, treatment failure, and comorbidities on the cost of HIV care is not well understood. OBJECTIVE: To characterize the cost of HIV care including combination antiretroviral treatment (ART). RESEARCH DESIGN: Observational study of administrative data. SUBJECTS: Total 1896 randomly selected HIV-infected patients and 288 trial participants with multidrug-resistant HIV seen at the US Veterans Health Administration (V…

The effect of homelessness on hospitalisation among patients with HIV/Aids
The purpose of this study was to determine the effect of homelessness on the costs and patterns of hospitalisation in patients with HIV/AIDS. A retrospective longitudinal study design, based on medical records data covering 2,768 person-years of observation between 1997 and 2003 on patients with HIV/AIDS, was employed. A contextual measure of neighbourhood socioeconomic status (SES) was also used to uncover differences among low- and high-SES nei…
