Background and aim: Supervised injecting facilities (SIF) are intended to reduce the harm related to illicit intravenous drug use. The aim of the study was to map the location of current injecting practices of people who inject drugs (PWID) in Cork, Ireland, and to document the related high-risk behaviours, ahead of a planned supervised injecting facility.

Methods: A cross sectional survey, utilizing geo- mapping software (GMS) mapping, was offered to PWID, at sites within the homeless services, needle exchange, and addiction services. Data was analysed using GPS mapping, and descriptive and inferential statistics.

Results: 51 PWID completed the survey (98% response), 66.67% were male. The age range was 20-55 years (mean age 30.78 years). 56.9% were in stable accommodation, with 43.1% currently homeless. 92.16% had been tested for HIV/Hepatitis C. 31.5% reported injecting into “high risk” areas (groin and neck), 72.55% injected alone. 58.82% reported injecting at least three times/day, 35.29% reported injecting at least four times/day. 54.9% reported sharing equipment/ needles. 58.82% had previously overdosed. 89.3% of recalled overdoses involved an emergency services response. Correlation between history of accidental overdose, and injecting alone was statistically significant (p = 0.039), as was previous history of overdose and injecting at least three times per day (p = 0.012). 86.27% indicated they would use a SIF. A mapping exercise presented visual information around injecting sites, locations of overdoses, fatal overdoses, and preferred location of the SIF.

Conclusions: The study provides an understanding of PWID profile and risk behaviours, alongside a geospatial analysis of injecting, overdose and potential location of a SIF in Cork, Ireland. The findings are intended to inform SIF location, and would allow dynamic comparison of both geographic and behavioural changes injecting drug use over time, post SIF provision.
