Few studies have examined factors that facilitate recruitment of small independent practices (SIPs) (<5 full-time clinicians) to participate in research and methods for optimizing retention. The authors analyzed qualitative data (eg, recruiter's field notes and diary entries, provider interviews) to identify barriers and facilitators encountered in recruiting and retaining 257 practices in HealthyHearts New York City (NYC). This study was a stepped-wedge randomized controlled trial that took place 2015 through 2018 across 5 boroughs in NYC. Three main factors facilitated rapid recruitment: (1) a prior well-established relationship with the local health department, (2) alignment of project goals with practice priorities, and (3) providing appropriate monetary incentives. Retention was facilitated through similar mechanisms and an ongoing multifaceted communication strategy. This article identifies specific strategies that enhance recruitment of SIPs and fills gaps in knowledge about factors that influence retention in the context of a design that requires waiting to receive the intervention.
