What the survey said: death rates for heart operations

A mortality figure of 100 means the number of deaths was exactly as expected taking into account factors beyond the hospital's control such as the age and sex of patients, the diagnosis and whether admission was planned or emergency.

trusts with figures lower than 100 are doing better than expected given their patient mix and vice versa.
