Three Infections, One Fight: Mapping Needle Prevalence and Evaluating Prevention Interventions in Regina, Saskatchewan
Introduction
Saskatchewan is currently experiencing a severe public health crisis with elevated rates of HIV, syphilis, and hepatitis C virus (HCV) infections, especially among people who use drugs. Injection drug use is a key factor contributing to the spread of these diseases. Social and structural barriers, including stigma, poverty, and limited culturally appropriate healthcare, amplify these challenges.
There is an urgent need for innovative, community-driven strategies to strengthen prevention, testing, and connections to care across affected populations.
Methods and Analysis
The study introduces a rapid assessment and response system in Regina, Saskatchewan, Canada. It combines geospatial mapping of needle distribution with community-based pop-up interventions targeting areas with high needle prevalence.
- Hotspot maps will guide the planning of pop-up events offering point-of-care testing for HIV, syphilis, and HCV.
- These events will provide education on pre-exposure (PrEP) and post-exposure prophylaxis (PEP).
A participatory mixed-methods approach will evaluate the feasibility, acceptability, and impact of these interventions, applying the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.
Evaluation
Quantitative data will measure:
- Changes in knowledge related to PrEP and PEP.
- Participant satisfaction with the interventions.
- New diagnosis rates and core demographic insights.
A qualitative component involving 30 participants will further explore personal experiences, barriers to care, and perceptions of service delivery within the intervention framework.
“Injection drug use is a major contributor to these syndemic infections, exacerbated by structural barriers such as stigma, poverty and limited culturally safe healthcare.”
