Enhancing the Role of Commune Health Workers in HIV and Drug Control: A Randomized Controlled Trial

Enhancing the Role of Commune Health Workers in HIV and Drug Control: A Randomized Controlled Trial

This proposed study is an initiative for HIV prevention and care that integrates intervention efforts at multiple strata: Community Health Workers (CHWs), Injecting Drug Users (IDUs), and their Family Members (FMs). The proposed study will demonstrate the process of development, implementation, and evaluation of an intervention for CHWs, IDUs, and their FMs. One aim is to increase the CHWs' capacities to effectively interact with IDUs and FMs for HIV and drug use prevention and treatment. Using a combination of participatory action research and a randomized controlled trial design, this study has the potential to maximize PEPFAR impact in Vietnam and other PEPFAR-funded countries by identifying a sustainable mix of interventions and their implementation in different settings. The findings may benefit not only Vietnam but also a global audience by investigating enhanced methods for controlling the HIV epidemic.

Vietnam is currently facing an HIV epidemic that had affected approximately 280,000 people by the end of 2009. Injecting Drug Use (IDU) is principal driver of the HIV epidemic, contributing to between 32 % and 58 % of all HIV cases in various provinces. However, it has proven difficult to address the needs of IDUs, a high-risk group, given the prevalence of stigmatization and drug use in Vietnamese society. In addition, Vietnamese people are highly family oriented and most young IDUs have daily family contact of live in their parents' homes. Thus the burden on the family is substantial, and even greater if the IDU is HIV+.

The study will be implemented in two provinces in Vietnam: Phu Tho and Vinh Phuc. A randomized controlled trial will be conducted to evaluate the impact of the intervention in 60 commune health centers. From each center we will recruit 5 Community Health Workers (CHWs), 15 Injecting Drug Users (IDUs), and 10 Family Members (FMs) (totaling 300 CHWs, 900 IDUs, and 600 FMs). The outcomes will be evaluated at 3-, 6-, 9-, and 12- month follow-up assessments. The specific aims of the study are as follows:

1. To develop and implement an integrated intervention, CHW CARE, for CHWs, IDUs, and their FMS in Vietnam
2. To evaluate the feasibility and operational procedures of the intervention with an implementation pilot, including process evalution and monitoring, and participants feedback.
3. To assess the impact of the intervention by comparing outcome measures of CHWs, IDUs, and FMs in the intervention group to those in the control group.
4. To explore the relationships between the intervention outcomes of CHWs, IDUs, and FMs.
