Abstract
Out-of-hospital cardiac arrest (OHCA) is a pressing public health concern that occurs approximately 350,000 times per year. Large disparities exist in outcomes for OHCA victims, with return of spontaneous circulation (ROSC) rates estimated to range from 6.1% to 52.5% across EMS agencies in Michigan. We sought to identify factors underlying this variation in performance. Leveraging a sequential mixed-methods approach, we first used data from the Michigan Cardiac Arrest Registry to Enhance Survival (CARES) to assess rates of sustained prehospital ROSC identifying high-, middle-, and low-performing systems. We then conducted semi-structured interviews and multidisciplinary focus groups with OHCA system of care stakeholders at 9 EMS sites of varying performance across Michigan to identify best practices among disparate systems of care. We used a qualitative content analysis approach, followed by a matrix analysis, to conduct both within and cross-site analyses and develop findings. Factors contributing to OHCA were divided into direct and indirect factors. Direct factors focused on incident-level care (e.g., proximity-based dispatch, incident debriefing). Indirect factors were broken down into stakeholder-level factors (e.g., agency culture, community preparedness) or system-level factors (e.g., interdisciplinary training, standardization). This research expands existing knowledge on how to optimize OHCA care and proposes a system of care’s best practices for enhancing outcomes and may contribute to increased OHCA performance across varied systems.
