Weekend versus Weekday Admission and In-Hospital Mortality from XXXX in Japan.

@entity1 @entity64 @entity385
BACKGROUND: The initial treatment of acute @entity385 critically affects @entity1 outcome. @entity1 outcome may also be associated with the day of hospital admission due to differences in the number of the hospital staff between weekdays and weekends. We aimed to assess the effect of weekend admission on in-hospital mortality among @entity1 with @entity385 in Japan. METHODS: We analyzed @entity1 with @entity385 from a large nationwide administrative dataset. The @entity1 were grouped according to the treatment ward to which they were initially admitted: a general medical ward (GMW) or an intensive or @entity64 care unit (S-ICU). The primary outcome, in-hospital mortality, was compared between the @entity1 admitted on a weekday versus weekend according to the initial treatment ward. A generalized estimated equation was applied for multivariate analysis. RESULTS: In total, 47,885 @entity1 were included in the study. Of these @entity1 , 32.0% were admitted to an S-ICU and 27.8% were admitted to a GMW on a weekend. The estimated in-hospital mortality rate was significantly higher among the @entity1 admitted to a GMW on a weekend compared with those admitted on a weekday (7.9% versus 7.0%), but this difference was not significant after adjusting for the @entity1 ' background characteristics. The estimated in-hospital mortality rates of the @entity1 admitted to an S-ICU were similar between weekend and weekday admissions (10.0% versus 9.9%). CONCLUSIONS: No significant effect of weekend admission in-hospital mortality was observed in our study population regardless of the initial treatment ward.
