Increased mortality for admissions at the weekend
The study looked at 14 million admissions to NHS hospitals during the 2009/10 financial year. Of these, 300,000 patients died within 30 days of admission. These deaths occurred either in hospital or after the patient had been discharged.
Patients had a 16% greater risk of death within the 30 day period if they'd been admitted on a Sunday than if admitted on a Wednesday. That's adjusting for things like the age of patients or their social deprivation, which might otherwise have distorted the result. For patients admitted on Saturday the risk was was 11% higher than for Wednesday, and for Monday it was 2%. On other days of the week there was no statistically significant difference.
