| Abstract: | Aim: To evaluate the cost‐effectiveness of needle and syringe programmes (NSPs) compared with no NSPs on hepatitis C virus (HCV) transmission in the United Kingdom. Design Cost‐effectiveness analysis from a National Health Service (NHS)/health‐provider perspective, utilizing a dynamic transmission model of HCV infection and disease progression, calibrated using city‐specific surveillance and survey data, and primary data collection on NSP costs. The effectiveness of NSPs preventing HCV acquisition was based on empirical evidence. Setting and participants: UK settings with different chronic HCV prevalence among people who inject drugs (PWID): Dundee (26%), Walsall (18%) and Bristol (45%) Interventions: Current NSP provision is compared with a counterfactual scenario where NSPs are removed for 10 years and then returned to existing levels with effects collected for 40 years. Measurements HCV infections and cost per quality‐adjusted life year (QALY) gained through NSPs over 50 years. Findings Compared with a willingness‐to‐pay threshold of £20 000 per QALY gained, NSPs were highly cost‐effective over a time‐horizon of 50 years and decreased the number of HCV incident infections. The mean incremental cost‐effectiveness ratio was cost‐saving in Dundee and Bristol, and £596 per QALY gained in Walsall, with 78, 46 and 40% of simulations being cost‐saving in each city, respectively, with differences driven by coverage of NSP and HCV prevalence (lowest in Walsall). More than 90% of simulations were cost‐effective at the willingness‐to‐pay threshold. Results were robust to sensitivity analyses, including varying the time‐horizon, HCV treatment cost and numbers of HCV treatments per year. Conclusions: Needle and syringe programmes are a highly effective low‐cost intervention to reduce hepatitis C virus transmission, and in some settings they are cost‐saving. Needle and syringe programmes are likely to remain cost‐effective irrespective of changes in hepatitis C virus treatment cost and scale‐up. [ABSTRACT FROM AUTHOR] |
