Abstract

Purpose: A randomized controlled trial with a matched design was conducted during October 2008 and February 2010, aiming at reducing HIV-related stigma in healthcare settings.

Methods: Forty county hospitals in Fujian and Yunnan provinces of China were matched into pairs and randomized to either an intervention condition or a control condition. Forty-four service providers were randomly selected from each hospital, yielding a sample of 1,760. Intervention outcomes were assessed at baseline, 6 and 12 months based on venue-based pair comparisons. We identified and trained 30 popular opinion leaders in each intervention hospital among service providers to disseminate stigma-reduction messages to their peer providers.

Results: Hospital and participant characteristics were comparable between the intervention and control conditions. Thirteen out of twenty pairs of hospitals showed significant reduction in the stigma outcome measure at the 6-month follow-up assessment. For most hospitals, the intervention effects were maintained at the 12-month follow-up assessment. Among the 13 pair of hospitals, which showed intervention effects at 6 months, eight were in Fujian and five were in Yunnan. The non-significant hospitals at 6 months had more beds than significant hospitals. However, the difference did not reach statistical significance.

Conclusions: A matched design and venue-based analysis provide more insight in assessing intervention effects for facility-based intervention trials. The identification of venue-based or hospital characteristics that are associated with intervention efficacy provides additional implications for the adaptation and implementation of future interventions.
