BACKGROUND: Optimal management of @entity1151 ( @entity1151 ) requires medical expertise, diagnostic testing, and therapies that may not be available consistently throughout the entire week. We sought to assess whether associations exist between weekday or weekend admission and mortality and length of hospital stay for @entity1 hospitalized with @entity1151 . METHODS AND RESULTS: We evaluated @entity1 discharged with a primary diagnosis of @entity1151 from 186 acute care hospitals in Pennsylvania (January 2000 to November 2002). We used random-effect logistic models to study the association between weekend admission and 30-day mortality and used discrete survival models to study the association between weekend admission and time to hospital discharge, adjusting for hospital (region, size, and teaching status) and @entity1 factors (race, insurance, severity of illness, and use of thrombolytic therapy). Among 15 531 @entity1 discharges with @entity1151 , 3286 @entity1 (21.2%) had been admitted on a weekend. @entity1 admitted on weekends had a higher unadjusted 30-day mortality rate (11.1% versus 8.8%) than @entity1 admitted on weekdays, with no difference in length of stay. @entity1 admitted on weekends had significantly greater adjusted odds of dying (odds ratio 1.17, 95% confidence interval 1.03 to 1.34) than @entity1 admitted on weekdays. The higher mortality among @entity1 hospitalized on weekends was driven by the increased mortality rate among the most severely ill @entity1 . CONCLUSIONS: @entity1 with @entity1151 who are admitted on weekends have a significantly higher short-term mortality than @entity1 admitted on weekdays. Quality-improvement efforts should aim to ensure a consistent approach to the management of @entity1151 7 days a week.
