Innovative Implementation Studies Conducted in US Safety Net Health Care Settings: A Systematic Review

Little is known about dissemination and implementation in safety net settings. The authors conducted a literature review of innovation/implementation studies in US safety net health care settings between 2008 and 2017. Each article was coded for (1) intervention characteristics, (2) implementation stage, (3) internal versus external ownership, and (4) prespecified implementation outcomes (eg, acceptability and fidelity). Twenty studies were identified; the majority were implemented within community clinics or integrated safety net systems (15 articles), most involved care process improvements (13 articles), and most were internally developed (13 articles). The internally developed innovations reported fewer barriers to acceptability among staff/providers, higher leadership involvement and organizational alignment, greater amounts of customization to the local setting, and better sustainment. Future work should harness the high levels of alignment and acceptability in implementation research within safety net settings, with an eye toward maintaining fidelity to facilitate dissemination across sites.
