STAGE 5. Defining the action plan
What steps should be completed?
Step 1: Specify intervention actions
The implementation of harm reduction strategies in many countries since the early 1990s (notably, SEP among injecting drug users) reduced the incidence of human immunodeficiency virus (HIV) infection or kept the prevalence of the infection low in this population.1 A report written for the World Health Organization in 20042 on the effectiveness of SEP in preventing HIV/AIDS infection in injecting drug users gave a clearly positive result for these programmes, concluding that:
Access to syringes in pharmacies as a complement to exchange programmes reduces injection-related hazardous behaviours. The combination of replacement treatments (methadone or buprenorphine) and SEP also helps reduce the incidence HIV and hepatitis C virus (HCV) transmission.3
However, a subsequent review of the scientific literature4 to determine the strength of evidence for the results of SEP concluded that they are beneficial, but the level of evidence is moderate. Along the same lines, a recent meta-analysis5 indicates that evidence for the effectiveness of these programmes is weaker than had been attributed, particularly in preventing HCV transmission, as the reduction in hazardous injecting behaviour seems insufficient to counteract the high levels of transmission of the infection. More studies are required to determine the coverage of interventions required to achieve sustained changes in HIV and HCV transmission. Including elements of peer education, and community support and participation also seems essential for these programmes to succeed.6 If you plan to implement a SEP in your community, One Step@a Time suggests that you consult the World Health Organization guide to starting and managing these programmes:
