A Semi-Factorial Cluster-Randomized Trial to Estimate the Effect Size of Community Mobilization and VCT Vans on the Adoption of Voluntary Counseling and Testing (VCT) Services in Andhra Pradesh, India: THE MCVCT STUDY

With an estimated 2.5 million HIV-infected persons, India is home to one of the largest populations of HIV-infected persons in the world. Yet, it is estimated that less than 20% of the people living with HIV in India are aware of their status. Andhra Pradesh (AP), situated in south India, is the state with the highest HIV burden in India. Reports from AP suggest usage of voluntary counseling and testing (VCT) is low, especially among high-risk groups. VCT has been shown to have many benefits in addition to diagnosis of HIV infection such as reduction in risk behavior, partner referral, and serving as an entry point to the health care system. Community mobilization and VCT vans have been shown in the past to play a role in increasing utilization of VCT services in various developing countries similar to India. The primary objective of this protocol is to arrive at an effect size of community mobilization alone, and both community mobilization and VCT vans, on the adoption of VCT services in Andhra Pradesh, India. Secondary objectives include identifying barriers to VCT, assessing stigma in the community, and establishing a specimen repository at the YRGCARE infectious disease laboratory in Chennai, India. We will achieve these objectives by conducting a cluster randomized clinical trial with 3 arms: ARM 1: standard of care with pre-existing VCT centers (SVCT); ARM 2: community mobilization in the setting of pre-existing VCT centers (CVCT); ARM 3: community mobilization plus VCT van in addition to the pre-existing VCT centers (MCVCT). The overall study duration will be 6 months from randomization. To our knowledge, this is the first study to examine the role of community mobilization and VCT vans on the adoption of VCT in the Indian context. It will provide us with vital data that will be used to plan a larger powered study to evaluate the effectiveness of these interventions including sites from other parts of India. Additionally, this study will also provide us with important information on barriers to VCT in these communities.
