Biomedical HIV/AIDS Prevention Program Yunnan

B-HAPPY is an implementation project to study the process by which pre-exposure prophylaxis (PrEP) is introduced and integrated into a specific international health system facing high rates of HIV incidence among men who have sex with men. The study will use a stepped wedge design to compare implementation outcomes across eight municipalities in Yunnan, China.

B-HAPPY is an implementation science project that will introduce and evaluate the implementation of PrEP among over 1000 men who have sex with men (MSM), in eight municipalities in Yunnan, China. The project aims to compare the effectiveness of two implementation strategy bundles: 1) Standard Implementation: comprising the strategies that the Yunnan Center for Disease Control and Prevention would usually use to introduce HIV prevention innovations in the absence of the proposed study; and 2) Enhanced Implementation: standard implementation enhanced by a SIC-guided approach to plan and implement PrEP.

This study will use a stepped-wedge design, where sites will go through four study periods: a Pre-Baseline Period (Routine Service with no PrEP Implementation), a Baseline Period (Standard Implementation of PrEP), an Experiment Period (Enhanced Implementation of PrEP), and a Post-Experiment-Observation Period. Sites are randomized to the timing of the intervention initiation, with 2 sites moving from Standard Implementation to Enhanced Implementation every 6 months. The intervention condition changes over time and the intervention effect is the difference in outcomes between the Baseline and Experiment Periods, and the Post-Experiment and Baseline Periods.

The specific aims of the proposed study are:

1. To evaluate whether the addition of SIC-guided PrEP delivery (Enhanced Implementation) to standard health system PrEP delivery improves services outcomes. Through a stepped-wedge randomized trial across eight Yunnan municipalities, within site change over time will be examined; timing of introduction of Enhanced Implementation will be randomized across four cohorts of two sites each. Client-services outcomes include progress to achieving the "Five-80s" (patient PrEP awareness, screening, offering, initiation, continuation).
2. To examine the implementation process and efficiency of the Enhanced versus Standard implementation approaches. Using the Stages of Implementation Completion (SIC) and Cost of Implementing New Strategies (COINS) tools, sites will be monitored for implementation process and resource use. Outcomes will include proportion of implementation activities completed; duration of each implementation phase; and cost and resource allocation for completion of each implementation phase.

Eligibility Criteria:
This study will recruit two types of study participants: A. MSM clients at study sites; B. study staff who will be involved in the implementation of this project.
