Abstract

Objectives: To evaluate the efficacy of an intervention targeted to commune health workers (CHWs) who deliver services to people who inject drugs (PWID) in Vietnam.

Methods: From 2014 to 2016, we conducted a cluster randomized controlled trial of 300 CHWs and 900 PWID in 60 communes in 2 provinces of Vietnam. Intervention CHWs participated in training sessions to enhance their communication skills. Trained CHWs were asked to deliver individual sessions to PWID. We assessed the outcomes at baseline and at 3-, 6-, 9-, and 12-month follow-ups.

Results: Intervention CHWs showed greater improvement in provider-client interactions than did control CHWs at all follow-ups (range of difference = 3.33-5.18; P < .001). Intervention CHWs showed greater reduction in negative attitudes toward PWID at the 12-month follow-up (mean ±SD = 1.75 ±0.50; P < .001). PWID in the intervention group exhibited greater improvement in drug avoidance than did those in the control group from the 6-month follow-up on (range of difference = 1.21-1.65; P < .001). We observed no intervention effect on heroin use as measured by urinalysis.

Conclusions: This intervention targeting CHWs could lead to desired outcomes for both CHWs and PWID. ClinicalTrials.gov: NCT0213092.1.
