This indicator is designed to accompany the SHMI publication.
The SHMI includes all deaths reported of patients who were admitted to non-specialist acute trusts in England and either died while in hospital or within 30 days of discharge. Deaths related to COVID-19 are excluded from the SHMI.
A contextual indicator on the percentage of deaths reported in the SHMI which occurred in hospital and the percentage which occurred outside of hospital is produced to support the interpretation of the SHMI.
Notes:
1. In the June 2025 publication, for University Hospitals of Derby and Burton NHS Foundation Trust (trust code RTG), there has been a large increase in the number of deaths where the discharge method has been set to discharged instead of died. This is making it appear as if most of the trust deaths are occurring outside of hospital. The low percentage of deaths occurring in-hospital for this trust should therefore be treated with caution.
2. There is a shortfall in the number of records for The Shrewsbury and Telford Hospital NHS Trust (trust code RXW), and Wirral University Teaching Hospital NHS Foundation Trust (trust code RBL). Values for these trusts are based on incomplete data and should therefore be interpreted with caution.
3. A number of trusts are now submitting Same Day Emergency Care (SDEC) data to the Emergency Care Data Set (ECDS) rather than the Admitted Patient Care (APC) dataset. The SHMI is calculated using APC data. Removal of SDEC activity from the APC data may impact a trust’s SHMI value and may increase it. More information about this is available in the Background Quality Report.
