Detail

The Summary Hospital-level Mortality Indicator (SHMI) is the ratio between the actual number of patients who die following hospitalisation at the trust and the number that would be expected to die on the basis of average England figures, given the characteristics of the patients treated there.

It covers all deaths reported of patients who were admitted to non-specialist acute trusts in England and either die while in hospital or within 30 days of discharge. This publication of the SHMI relates to discharges in the reporting period July 2015 to June 2016.

To help users of the data understand the SHMI, trusts have been categorised into bandings indicating whether a trust’s SHMI is ‘higher than expected’, ‘as expected’ or ‘lower than expected’.
