Abstract
Opiate substitution treatment and needle exchanges have reduced blood borne virus (BBV) transmission among people who inject drugs (PWID). Psychosocial interventions could further prevent BBV. A systematic review and meta-analysis examined whether psychosocial interventions (e.g. CBT, skills training) compared to control interventions reduced BBV risk behaviours among PWID. 32 and 24 randomized control trials (2000-May 2015 in MEDLINE, PsycINFO, CINAHL, Cochrane Collaboration and Clinical trials, with an update in MEDLINE to December 2016) were included in the review and meta-analysis respectively. Psychosocial interventions appear to reduce: sharing of needles/syringes compared to education/information (SMD −0.52; 95% CI −1.02 to −0.03; I2 = 10%; p = 0.04) or HIV testing/counselling (SMD −0.24; 95% CI −0.44 to −0.03; I2 = 0%; p = 0.02); sharing of other injecting paraphernalia (SMD −0.24; 95% CI −0.42 to −0.06; I2 = 0%; p < 0.01) and unprotected sex (SMD −0.44; 95% CI −0.86 to −0.01; I2 = 79%; p = 0.04) compared to interventions of a lesser time/intensity, however, moderate to high heterogeneity was reported. Such interventions could be included with other harm reduction approaches to prevent BBV transmission among PWID.
