In- XXXX hospital mortality patterns by day of the week: an analysis of admissions to a regional renal unit.

@entity1 @entity4736 @entity204 @entity810
BACKGROUND AND AIMS: Higher mortality rates have been reported for @entity1 admitted at a weekend compared to a weekday. Our aim was to assess in- @entity1 mortality patterns by day of the week, in a tertiary renal unit. METHOD AND RESULTS: Mortality related to day of admission and day of @entity204 was analysed over a two-year period at Glasgow Western Infirmary renal unit. Typical caseload was also assessed over two random four-week periods. As a proportion of admissions, 30-day mortality was 46/540 (8.5%) on a weekend day compared with a weekday 107/2013 (5.3%) ( @entity4736 .60, p   =   0.005). Thirty-day mortality rate was 46/208   =   0.22 @entity204 /weekend day of admission compared with 107/523   =   0.20 @entity204 /weekday of admission (incident rate ratio   =   1.08, p   =   0.67). There was no significant increased risk of @entity204 on a weekend day compared to a weekday ( @entity4736 .23, p   =   0.23). A higher proportion of weekend admissions were from other hospitals. @entity810 and haemodialysis @entity1 formed a higher percentage of admissions. CONCLUSION: Admission day mortality expressed as a @entity204 rate/day does not differ between weekend/weekday admissions. Admission day mortality expressed as a proportion of total admissions was significantly higher at weekends. This suggests admission case-mix/workload differs at weekends with fewer 'well' @entity1 admitted. In- @entity1 mortality patterns are complex and any conclusions made should take into account case mix and workload.
