Discriminant Function Analyses: Classifying Drugs/Violence Victimization Typologies Among Incarcerated Rural Women

Increasing trends and incidence of nonfatal overdose among women sex workers who use drugs in British Columbia: The role of criminalization-related barriers to harm reduction

BACKGROUND

Structurally marginalized women who use drugs experience disproportionately elevated health and social inequities that require specialized responses to mitigate risk of overdose. This study aimed to longitudinally investigate incidence and predictors of first nonfatal overdose among women sex workers who use drugs.

METHODS

Data (2010-2019) were drawn from AESHA (An Evaluation of Sex Workers Health Access), a community-based, prospective, open cohort of > 900 women sex workers in Metro Vancouver, Canada. Incidence was examined and Cox regression modelled time-updated predictors of first nonfatal overdose. Time series analysis examined annual trends.

RESULTS

Among 273 eligible participants, 23% (n = 63) reported a first nonfatal overdose over follow-up with an incidence density of 5.87/100 person-years. In multivariable analysis, independent predictors of time to nonfatal overdose were police-related barriers to harm reduction (Adjusted Hazard Ratio [AHR]=2.62; 95% confidence interval [CI] 1.51-4.54), binge alcohol use (AHR=2.28; 95%CI 1.16-4.45), opioid use (AHR=2.23; 95%CI 1.15-4.33), and crystal methamphetamine use (AHR=2.07; 95%CI 1.27-3.39). Time series analysis demonstrated a significantly increasing trend in first nonfatal overdose, with annual proportions increasing 0.59% (95%CI 0.39-0.78%) every year, on average.

CONCLUSIONS

This study provides strong longitudinal evidence from the longest-standing cohort of sex workers in North America. Nonfatal overdose in this setting is a critical public health concern. Criminalization-related barriers to harm reduction strongly predicted nonfatal overdose. Structural changes to legal and policing practices alongside gender-sensitive addiction services are urgently needed.

Designing and implementing an intervention for returning citizens living with substance use disorder: discovering the benefits of peer recovery coach involvement in pilot clinical trial decision-making

Peer-facilitated services in behavioral health care remain underutilized within criminal justice-involved community organizations, and there is little guidance for how to best involve peer workers in behavioral health-focused research activities. This paper described lessons learned regarding implementation of peer recovery coaches (PRCs) as part of development and pilot research on Substance Use Programming for Person-Oriented Recovery and Treatment (SUPPORT), a peer-facilitated substance use disorder (SUD) intervention for returning citizens. Qualitative data were collected from learning meetings with key stakeholders and group interviews with SUPPORT clinical trial participants and PRCs. Transcripts were analyzed to identify key decisions made impacting the development, implementation, and/or revision of the SUPPORT intervention and pilot clinical trial protocols. Analysis demonstrated that PRC involvement drove many of the decisions made regarding modifications to the original intervention and trial protocols, while benefitting client-level interactions and by influencing the non-profit agency and its connection to stakeholders. Moreover, PRCs improved the research design by refining the incentive structure and data collection plans. PRC involvement also contributed to the development of more recovery-oriented resources and catering support services to the unique needs of justice-involved individuals. Discussed were the implications for the role of PRCs in justice-involved behavioral health research and treatment.
