Excess under 75 mortality rates in adults with serious mental illness - 2018 to 2020

Experimental statistics


This indicator is a measure of the extent to which adults with a serious mental illness (SMI) die younger than adults without a serious mental illness (nSMI).

To measure premature mortality in adults diagnosed with a serious mental illness (SMI).

Data published from August 2021 uses a new methodology which takes advantage of an improved person identifier which will allow the timeseries to be extended in the future. Comparisons should not be made with data published previously for this indicator using other methodologies.

ONS have changed the way that all deaths are classified from 1 January 2020. The change involved a change of software from IRIS 4.2.3 to MUSE 5.5. As such, the underlying condition breakdowns are not included in this release while NHS Digital assess the impact of these changes and the underlying conditions breakdown will be published at a later date.
