Reduction or cessation of injecting risk behaviours? Treatment outcomes at 1-year follow-up.
This paper investigates changes in injecting and shared use of needles and syringes among 732 drug misusers recruited to residential and community treatment programmes as part of the National Treatment Outcome Research Study (NTORS). Specifically, it investigates whether reductions in these behaviours were due to a move away from injecting among drug users or whether they could be accounted for by drug users becoming abstinent. Injecting and sharing of injecting equipment were substantially reduced after treatment. Outcomes were due to reduced sharing among injectors, reduced injecting among continuing users and to users becoming abstinent. Clients from residential programmes were more likely to be abstinent at follow-up: methadone clients were more likely to be injecting but not sharing. Abstinence and intermediate risk reduction outcomes were achieved by many drug injectors from both treatment settings. Both outcomes confer benefits, though the benefits of abstinence are greater. Users who were injectors at intake but who had stopped injecting at follow-up consistently achieved superior outcomes across a range of problem behaviours.
