826-P: Application of Health Services Outcome Research Approaches to Refine Pragmatic Trial Design during COVID-19

Design of a pragmatic trial requires planning of key components (cohort identification, participant recruitment, consent and enrollment, intervention delivery, and outcomes measurements). The delivery of healthcare was significantly disrupted by COVID-19;this also affected research. We applied health services and outcomes research (HSOR) methods to inform design adaptations of trial components. The trial is an intervention to improve self-care of patients with diabetes mellitus (DM), discharged from the hospital on insulin. Key informant interviews, clinical observations (N=5), patient tracers (N=5), and operational data were gathered from health system stakeholders (N=9), clinicians (N=20), and measurement experts (N=2). Table 1 describes the trial components, HSOR approaches, data sources, and results. A cohort identification algorithm was created using enterprise data warehouse (EDW) data and validated by chart review, and 3 clinical care process maps were produced. Multiple options for each trial component, allowing for flexibility should care disruptions occur, were identified and pretested (N=5). HSOR approaches are effective to rapidly adapt trial design components, even during healthcare delivery disruptions that threaten research. Application of these approaches should be considered as a strategy to design resilient, flexible, and effective pragmatic trials.
