Estimating the burden of disease from unsafe injections in India: A cost-benefit assessment of the auto-disable syringe in a country with low blood-borne virus prevalence

Le résumé fourni par la source

BACKGROUND: Unsafe medical injections are a prevalent risk factor for viral hepatitis and HIV in India. OBJECTIVES: This review undertakes a cost-benefit assessment of the auto-disable syringe, now being introduced to prevent the spread of hepatitis B virus, hepatitis C virus, and human immunodeficiency virus (HIV). MATERIALS AND METHODS: The World Health Organization methods for modeling the global burden of disease from unsafe medical injections are reproduced, correcting for the concentrated structure of the HIV epidemic in India. A systematic review of risk factor analyses in India that investigate injection risks is used in the uncertainty analysis. RESULTS: The median population attributable fraction for hepatitis B carriage associated with recent injections is 46%, the median fraction of hepatitis C infections attributed to unsafe medical injections is 38%, and the median fraction of incident HIV infections attributed to medical injections is 12% in India. The modeled incidence of blood-borne viruses suggests that introducing the auto-disable syringe will impose an incremental cost of $46-48 per disability adjusted life year (DALY) averted. The epidemiological evidence suggests that the incremental cost of introducing the auto-disable syringe for all medical injections is between $39 and $79 per DALY averted. CONCLUSIONS: The auto-disable syringe is a cost-effective alternative to the reuse of syringes in a country with low prevalence of blood-borne viruses.
