Weekend and night outcomes in a statewide XXXX system.

@entity1 @entity130
OBJECTIVE: To evaluate whether mortality and clinical outcomes vary for injured @entity1 in a mature @entity130 system on weeknights and weekends compared with weekdays. DESIGN: Retrospective cohort study. SETTING: Pennsylvania @entity130 system. @entity1 : A total of 90,461 @entity1 over 5 years. INTERVENTION: Treatment at a level I, II, or III @entity130 center. MAIN OUTCOME MEASURES: In-hospital mortality, time to procedures, and length of stay. RESULTS: In adjusted analyses, @entity1 presenting on weeknights were no more likely to die than @entity1 presenting during weekdays, and @entity1 presenting on weekends were less likely to die than @entity1 presenting on weekdays (odds ratio = 0.89; 95% confidence interval, 0.81-0.97). Presenting on weeknights was associated with longer intensive care unit stay (incidence rate ratio = 1.06; 95% confidence interval, 1.02-1.10) and longer hospital stay (incidence rate ratio = 1.02; 95% confidence interval, 1.00-1.04). Presenting on weekends was associated with longer intensive care unit stay (incidence rate ratio = 1.04; 95% confidence interval, 1.02-1.10) but not longer hospital stay. Delays to laparotomy or craniotomy were not seen in either group. CONCLUSIONS: We demonstrate comparable mortality among injured @entity1 presenting on weeknights vs weekdays and lower mortality among injured @entity1 on weekends vs weekdays. Systems-based solutions of the @entity130 model are protective against the weekend effect and inform care for other emergency care-sensitive conditions.
