Systems Analysis and Improvement to Optimize Opioid Use Disorder Care Quality and Continuity for Patients Exiting Jail

SAIA is an evidence-based implementation strategy of bundled systems engineering tools designed to optimize complex healthcare delivery systems and improve linkages between clinical and community providers. The SAIA-MOUD study aims to strengthen the quality and continuity of MOUD care, and linkages to social services, across jail and referral clinics in King County, WA. The investigators will implement the SAIA for three years-including a two-year intensive phase and one year of sustainment-at one jail based MOUD program and three referral MOUD clinics. The investigators will then evaluate the effectiveness of SAIA on improving MOUD cascade quality and continuity for patients receiving care in jail and exiting to referral clinics, determining the effect of SAIA in the jail clinics on linkage to care for community-based MOUD clinics within 30 days of release. A secondary outcome of retention (those who return for a second MOUD pick up within 30 days of initial linkage) will be considered. The investigators will also describe-and explore determinants of-adoption, implementation, and sustainment of SAIA-MOUD via qualitative inquiry with jail and clinic staff. Analysis will be guided by the Consolidated Framework for Implementation Research (CFIR) and the Framework for Reporting Adaptations and Modification to Evidence-based Implementation Strategies (FRAME-IS) will be used to document implementation strategy adaptations. The investigators will estimate the cost and cost-effectiveness of SAIA-MOUD using the cost per quality-adjusted life year gained from the county government, healthcare sector, and societal perspectives. Using a micro-costing approach, the investigators will estimate the incremental costs of implementing and sustaining SAIA in jail and community-based clinics.
