CI=confidence interval; ICD-10=international classification of diseases, 10th revision.
Ordinary least squares estimates for total risk adjusted mortality indicators computed separately by ICD-10 chapter with (hospital×financial year) fixed effects. Other controls also included, but omitted from the table for brevity, are the standardised number of staff (nurses and senior doctors) and the quarter of year fixed effects. Standard errors clustered at hospital level.
Significance level: *P<0.1; **P<0.05; ***P<0.01.
