Data from: Weekend admission as an independent predictor of mortality: an analysis of Scottish hospital admissions

PRIMARY OUTCOME MEASURES: Death as recorded by the General Register Office (GRO). RESULTS: There was a significantly increased probability of death associated with a weekend emergency admission compared with admission on a weekday (unadjusted OR 1.27, 95% CI 1.26 to 1.28, p<0.0001; adjusted for year of admission, gender, age, deprivation quintile and number of comorbidities OR 1.42, 95% CI 1.40 to 1.43, p<0.0001). CONCLUSIONS: Despite a general reduction in mortality over the last 11 years, there is still a significant excess mortality associated with weekend emergency admissions.

Further research should be undertaken to identify the precise mechanisms underlying this effect so that measures can be put in place to reduce patient mortality.
