Abstract WP38: Variation In Performance On Stroke Care Delivery Measures Among Us Community Emergency Departments

Introduction: Many stroke patients initially present to non-stroke center hospitals. However, the delivery of Emergency Department (ED)-based acute stroke care at smaller, non-academic (i.e., community) EDs is less well-described than for larger, academic hospitals. Hypothesis: There is wide variation in community EDs’ performance on acute stroke care delivery measures. Methods: This is a retrospective analysis of a cohort of stroke patients from EDs participating in the Emergency Quality Network (E-QUAL) stroke collaborative, a national stroke quality improvement project targeted to community EDs. Sites used ICD10 codes to identify ischemic stroke patients and submitted data using a web-based submission portal. EDs with data from at least 20 patients were included. For each site, we calculated median door-to-imaging (DTI), door-to-needle (DTN), and door-in-door-out (DIDO) times among transferred patients and ED length of stay (LOS) among admitted patients. We also determined the proportions of eligible patients arriving with 3.5 hours of last known well who received thrombolysis within 4.5 hours, of patients with documentation of severity assessment performance and of dysphagia screening. We used descriptive statistics to illustrate variation. Results: Of the 54 participating EDs, data were available for 45, and 28 included ≥ 20 patients. Of included EDs, median annual ED volume was 34,648 (IQR 21,250-47,120) and 40% were rural. Performance varied on DTI, DIDO among transferred patients, and LOS among admitted patients (Table). Performance was more consistent on documentation of severity assessment and dysphagia screening. Conclusions: Performance on stroke care delivery measures varied between these community EDs and data in the literature from larger hospitals that typically participate in national registries. Future efforts to improve emergency stroke care delivery should consider unique factors impacting care at smaller, community EDs.
