HIV Pre-exposure Prophylaxis Program Implementation Using Intervention Mapping

HIV pre-exposure prophylaxis has been proven to be an effective tool in HIV prevention. However, numerous barriers still exist in pre-exposure prophylaxis implementation.

The framework of Intervention Mapping was used from August 2016 to October 2017 to describe the process of adoption, implementation, and maintenance of an HIV prevention program from 2012 through 2017 in Houston, Texas, that is nested within a county health system HIV clinic. Using the tasks outlined in the Intervention Mapping framework, potential program implementers were identified, outcomes and performance objectives established, matrices of change objectives created, and methods and practical applications formed.

Results include the formation of three matrices that document program outcomes, change agents involved in the process, and the determinants needed to facilitate program adoption, implementation, and maintenance. Key features that facilitated successful program adoption and implementation were obtaining leadership buy-in, leveraging existing resources, systematic evaluation of operations, ongoing education for both clinical and nonclinical staff, and attention to emergent issues during launch.

The utilization of Intervention Mapping to delineate the program planning steps can provide a model for pre-exposure prophylaxis implementation in other settings.
