Intervention

Intervention Overview

Intervention:
The proposed intervention to increase adult male attendance at VMMC involves a weekly raffle of Smartphones for VMMC clients and a separate Smartphone raffle for the peer promoters and providers for the duration of three months involving seven intervention facilities. VMMC clients enrolled in the study and returning within seven days for a follow up visit will be eligible for a Smartphone raffle. Peer promoters and providers get a single ticket for raffle for every five successful referrals. The raffle will follow Tanzania Gaming Board regulations. Objectives: (1)To assess whether a motivational incentive (entry into a Smartphone raffle) can achieve a net 20% increase (25% at intervention and 5% at comparison sites) in the number of VMMC clients aged 20 + at routine service delivery sites; (2)To assess whether a motivational incentive can increase the number of successful referrals to VMMC fixed sites made by peer promoters and health providers;(3)To understand and document the types of motivation that men have for seeking VMMC services in comparison sites, and in intervention sites;4)To compare the costs of providing VMMC services at intervention and comparison sites.

Method Details

Details of Evaluation Approach:
The evaluation will be conducted in 14 paired health facilities. There will be random assignment in each pair to intervention or comparison. Intervention sites will offer smart phone raffle. No matching or randomization for individuals. Based on the routine data from the Voluntary Medical Male Circumcision (VMMC) sites, approx. 600 men aged 20 + will receive VMMC services in intervention sites and approx. 600 men in comparison sites in the duration of 3 months. In the intervention sites these are eligible to participate in a weekly raffle. Intervention: Routine individual data for approx.600 VMMC clients aged 20+ A subset of these (approx. 256) will be randomly (from a list of raffle participants) selected to complete supplemental client form. 21 Peer Promoters (PP) for Focus Group Discussion (FGD),21 Health Care Providers (HCP) for provider interview. All PPs and HCPs referring clients to VMMC services will be eligible for a monthly raffle. Comparison: Routine individual data for approx. 600 VMMC clients aged 20+. 21 PP for FGD 21 HCP for provider interview. A PP is any person whose work is to raise awareness, inform, sensitize and promote VMMC in his/her community.
Outcomes (Endpoints):
1) Percentage increase in the number of VMMC clients aged 20 and above at routine service delivery sites during three months of intervention 2) Proportional increase of the number of successful referrals (referred and received VMMC) to VMMC made by peer promoters and health providers during the intervention period 3)Documented types of motivation that men have for seeking VMMC services in comparison sites and intervention sites 4) Documented costs of providing VMMC services at intervention and comparison sites
Unit of Analysis:
VMMC clients aged 20 and above at VMMC service delivery sites
Hypotheses:
1)An intervention using Smartphones will increase adult male attendence at VMMC by up to 20%. 2)An intervention using Smartphones will increase the number of successful referrals.
Unit of Intervention or Assignment:
The unit of assignment is a health facility. No assignment to study arm at the individual level
Number of Clusters in Sample:
Seven pairs of facilities have been selected that were purposefully matched based on location, patient volume and type of facility. One in each matched pair will be randomly assigned to intervention
Number of Individuals in Sample:
A maximum of 714 clients from intervention and comparison facilities will be involved
Size of Treatment, Control, or Comparison Subsamples:
Treatment: 600 VMMC clients; 42 peer promoters FGD; 21 providers. Comparison: 30 VMMC clients FGD and 21 Providers
