The aim of the Needle Exchange Surveillance Initiative (NESI) is to measure and monitor the prevalence of blood-borne viruses (hepatitis C virus (HCV) and HIV), other health harms, risk behaviours and uptake of harm reduction and health services among people who inject drugs in Scotland.
NESI is a key source of data to monitor and evaluate progress, nationally and locally, against Scotland’s blood-borne virus strategies, including the Scottish Government’s Sexual Health and Blood Borne Virus Action Plan and associated strategies on HCV elimination and HIV transmission elimination.
This report, alongside the data tables, presents the results of the latest NESI survey, undertaken in 2022-23.
Results are presented at a Scotland level across the eight surveys undertaken to date (from 2008-09 through to 2022-23), and at NHS board level for the 2022-23 survey.
