Hepatitis C virus (HCV) affects up to 45,000 people in Sweden today. Although it is a very treatable disease, the prevalence of HCV is extremely high within the population of people who inject drugs (PWID). This study examines the direct effect of needle exchange programs (NEPs) on HCV rates in Sweden. Previous research has shown that NEPs reduce the transmission of other blood-borne diseases among PWID. Using an interrupted time series (ITS) analysis, this study investigates if there are statistically significant differences between HCV rates in Swedish counties before and after the implementation of NEPs. The study also investigates via linear regression to see if there is a relationship between sterile injecting equipment (needles and syringes) dispensed and HCV rates in the counties where NEPs exist. While there has been a steady decrease in HCV rates across the country as a whole, the ITS analyses show no statistically significant differences in HCV rates due to the opening of NEPs. Because of the relatively recent introduction of NEPs in Sweden, more data points post-intervention may be needed before we can truly see the effect they have on regional HCV rates. There is also no relationship between the number of needles and syringes dispensed and county HCV rates. However, Sweden falls far short of the 300 syringes/needles per user per year recommendation of the World Health Organization at this time. Standardized data collection and further research can help answer these questions more clearly.
