RESUMO
OBJECTIVES: The purpose of this study was to identify the impact of COVID-19-related "shelter in place" restrictions on stroke metrics in two metropolitan Texas cities, Austin and San Antonio. MATERIALS AND METHODS: Data was derived from stroke quality metric registries and compared between two treatment periods: (1) during the state's COVID-19 "shelter in place" restriction period, and (2) the corresponding period during the previous year for Austin and San Antonio, Texas. Primary outcomes include the dichotomized process measures of time last known well (TLKW) to arrival, arrival to brain imaging initiation, and arrival to administration of thrombolytic therapy. Secondary outcomes are clinical endpoints: independent ambulation at discharge, discharge to home, and in-hospital mortality. RESULTS: Austin patients were older and presented with less-severe strokes. San Antonio patients were more likely to be Hispanic, suffer from a large vessel occlusion, and have independent ambulation at discharge (adjusted odds ratio, 2.04; 95% confidence intervals, (1.25-3.37). Within-city analyses revealed a trend toward increased TLKW to arrival in Austin and San Antonio during COVID-19. During COVID, Austin patients had decreased length of stay (LOS) while a higher proportion of San Antonio patients had a favorable outcome (discharged home & independent ambulation). CONCLUSIONS: Longer TLKW to hospital arrival during COVID did not impact arrival-to-imaging, arrival-to-treatment times nor patient outcomes, even in patients at higher risk for stroke. Future studies should continue to assess the impact of COVID-19 on stroke care and outcomes pre- and post-introduction of the COVID-19 vaccine, and as infectivity rates spike or recede.
