Spotlight On: Weekend Mortality
Several studies have identified higher mortality for patients admitted as emergencies at the weekend compared with emergency admissions during the week.
Spotlight on: Hospital mortality following the junior doctor changeover in August
We have carried out a follow-up analysis re-examining the previous killing season paper (including more recent data) on the effect of the junior doctor changeover in August.

Several studies have identified higher mortality for patients admitted as emergencies at the weekend compared with emergency admissions during the week. Using routinely collected hospital administrative data, we examined in-hospital deaths for all emergency inpatient admissions to all public acute hospitals in England for 2005/2006. Odds of death were calculated for admissions at the weekend compared to admissions during the week, adjusted for age, sex, socioeconomic deprivation, comorbidity and diagnosis. Of a total of 4 317 866 emergency admissions, we found 215 054 in-hospital deaths with an overall crude mortality rate of 5.0% (5.2% for all weekend admissions and 4.9% for all weekday admissions). The overall adjusted odds of death for all emergency admissions was 10% higher (OR 1.10, 95% CI 1.08 to 1.11) in those patients admitted at the weekend compared with patients admitted during a weekday (p<0.001).

We have carried out a follow-up analysis re-examining the previous killing season paper (including more recent data) on the effect of the junior doctor changeover in August. We found the odds of death for patients admitted on the first Wednesday in August was 6% higher (OR 1.06, 95% CI 1.00 to 1.13, p=0.05) after controlling for year, gender, age, socio-economic deprivation and co-morbidity.
