The application of implementation science methods in correctional health intervention research: a systematic review

Abstract

Background: Improving access to high-quality healthcare for individuals in correctional settings is critical to advancing health equity in the United States. Compared to the general population, criminal-legal involved individuals experience higher rates of chronic health conditions and poorer health outcomes. Implementation science frameworks and strategies offer useful tools to integrate health interventions into criminal-legal settings and to improve care. A review of implementation science in criminal-legal settings to date is necessary to advance future applications. This systematic review summarizes research that has harnessed implementation science to promote the uptake of effective health interventions in adult criminal-legal settings.

Methods: A systematic review of seven databases (Academic Search Premier, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Social Work Abstracts, ProQuest Criminal Justice Database, ProQuest Sociological Abstracts, MEDLINE/PubMed) was conducted. Eligible studies used an implementation science framework to assess implementation outcomes, determinants, and/or implementation strategies in adult criminal-legal settings. Qualitative synthesis was used to extract and summarize settings, study designs, sample characteristics, methods, and application of implementation science methods. Implementation strategies were further analyzed using the Pragmatic Implementation Reporting Tool.

Results: Twenty-four studies met inclusion criteria. Studies implemented interventions to address infectious diseases (n=9), substance use (n=6), mental health (n=5), co-occurring substance use and mental health (n=2), or other health conditions (n=2). Studies varied in their operationalization and description of guiding implementation frameworks/taxonomies. Sixteen studies reported implementation determinants and 12 studies measured implementation outcomes, with acceptability (n=5), feasibility (n=3), and reach (n=2) commonly assessed. Six studies tested implementation strategies. Systematic review results were used to generate recommendations for improving implementation success in criminal-legal contexts.

Conclusions: The focus on implementation determinants in correctional health studies reflects the need to tailor implementation efforts to complex organizational and inter-agency contexts. Future studies should investigate policy factors that influence implementation success, design, and test implementation strategies tailored to determinants, and investigate a wider array of implementation outcomes relevant to criminal-legal settings, health interventions relevant to adult and juvenile populations, and health equity outcomes.

Trial registration: A study protocol (CRD42020114111) was registered with Prospero.
