Mortality and other outcomes after paediatric hospital admission on the weekend compared to weekday

Mortality is higher for adults admitted to hospital and for babies born on weekends compared to weekdays. This study compares in-hospital mortality and in children admitted to hospital on weekends and weekdays. Details for all acute medical admissions to hospitals in Scotland for children aged ≤16 years between 1(st) January 2000 and 31(st) December 2013 were obtained. Death was linked to day of admission. There were 570,403 acute medical admissions and 334 children died, including 83 who died after an admission on Saturday or Sunday and 251 who died following admission between Monday and Friday. The adjusted odds ratio (aOR) for a child dying after admission on a weekend compared to weekday was 1.03 [95% CI 0.80 to 1.32]. The OR for a child admitted over the weekend requiring intensive care unit (ICU) or high dependency unit (HDU) care was 1.24 [1.16 to 1.32], but the absolute number of admissions to HDU and ICU per day were similar on weekends and weekdays. We see no evidence of increased in-hospital paediatric mortality after admission on a weekend. The increased risk for admission to ITU or HDU with more serious illness over weekends is explained by fewer less serious admissions.
