Enhancing the Role of Commune Health Workers in HIV and Drug Control: A Randomized Controlled Trial
Study Details
Study Description
Brief Summary
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.

Detailed Description
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:
-
To develop and implement an integrated intervention, CHW CARE, for CHWs, IDUs, and their FMS in Vietnam
-
To evaluate the feasibility and operational procedures of the intervention with an implementation pilot, including process evalution and monitoring, and participants feedback.
-
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.
-
To explore the relationships between the intervention outcomes of CHWs, IDUs, and FMs.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Control Community Health Workers (CHWs) in the control group will be invited to one group lecture didactically reviewing medical ethics, and the attending CHWs will be requested to pay a home visit to participating IDUs and FMs after the lecture. |
|
| Experimental: Intervention Intervention for CHWs: 3 sessions will cover the understanding stigma and its impact, self-protection and universal precaution adherence, effective communication with patients and family members, and motivational enhancement for behavioral change. Intervention for IDUs: CHWs who participate in the intervention will be required to conduct 3 individual sessions with participating IDUs covering the following topics: physical health, risk reduction behaviors, mental health, and community integration. Intervention for FMs: CHWs who participate in the intervention will be required to conduct 2 group sessions with participating FMs covering the following topics: healthy family routine, coping with caregiver burdens, enhance family relationships, support positive behavior change. |

Outcome Measures
Primary Outcome Measures
- Community Health Worker (CHW) Interaction with patients [Changes from baseline to 3-, 6-, 9- and 12- month follow-up]
Provider-Client interaction scale will be used.
- Injecting Drug User (IDU) drug use [baseline, 3-, 6-, 9- and 12- month follow-up]
Urine test results
Secondary Outcome Measures
- Community Health Worker (CHW) job safety, support, and satisfaction [Changes from baseline to 3-, 6-, 9-, and 12- month follow-up]
This will be assessed by perceived risk at work and institutional support. Additionally by job satisfaction using a 29-item scale.
- Community Health Worker (CHW) knowledge and adherence to universal precautions [Changes from baseline to 3-, 6-, 9-, and 12- month follow-up]
This will be assessed with the universal precautions knowledge scale.
- Injecting Drug User (IDU) family and social support [Changes from baseline to 3-, 6-, 9- and 12- month follow-up]
This is measured by two instruments. Social Support Questionnaire (Short; SSQ6) is a 6-item assessment to measure satisfaction of social support. Number of social support providers is captured up to 9 people in various support dimensions (Sarason et al., 1983). Medical Outcomes Study- Social Support Scale (MOS-SS) is a 20-item scale that measures the strength of perceived social support available. The scale consists of five dimensions: emotional support, informational support, tangible support, positive social interaction, and affection
- Family Member (FM) social support [Changes from baseline to 3-, 6-, 9-, and 12- month follow-up]

- Community Health Worker (CHW) general prejudicial attitude [Changes from baseline to 3-, 6-, 9- and 12- month follow-up]
A scale will be used
- Family Member (FM) Caregiver burden/coping [Changes from baseline to 3-,6-,9-, and 12-month follow-up]
Caregiver burden and coping scales will be used
