Weekday Versus Weekend Presentation in the Acute Management of Ischemic Stroke Through Telemedicine

摘要

A "weekend effect" resulting in higher mortality rates for patients with stroke admitted on weekends has been reported. We examine this phenomenon for patients with acute ischemic stroke (AIS) presenting to telestroke (TS) sites to determine its effect on stroke alert process times and outcomes. From October 2015 to June 2017, we reviewed patients with AIS receiving intravenous alteplase within our TS network. We compared patients presenting to TS sites on weekdays (Monday 07:00 to Friday 18:59) to those presenting on weekends (Friday 19:00 to Monday 06:59). We analyzed door-to-alert activation, alert activation-to-TS evaluation, door-to-imaging, and door-to-needle times. Rates of favorable outcome (modified Rankin Scale score <= 2) and death at 90 days were compared. We identified 89 (54 weekday and 35 weekend) patients (mean age: 71.8 +/- 13.3 years, 47.2% women) during the study period. Median door-to-alert activation (P = .01) and door-to-needle (P = .004) times were significantly longer for patients presenting on weekends compared to weekdays. There were no significant differences in median door-to-imaging (P = .1) and alert activation-to-TS evaluation (P = .07) times. Rates of favorable outcome (P = .19) and death (P = .56) at 90 days did not differ. While there were no significant differences in outcomes, patients presenting on weekends had longer door-to-alert activation and door-to-needle times. Efforts to improve methods in efficiency of care on weekends should be considered.
