These indicators are designed to accompany the SHMI publication.
The SHMI methodology includes an adjustment for admission method. This is because crude mortality rates for elective admissions tend to be lower than crude mortality rates for non-elective admissions.
Contextual indicators on the crude percentage mortality rates for elective and non-elective admissions where a death occurred either in hospital or within 30 days (inclusive) of being discharged from hospital are produced to support the interpretation of the SHMI. Notes:
1. There is a shortfall in the number of records for Buckingamshire Healthcare NHS Trust (trust code RXQ) and Mid Cheshire Hospitals NHS Foundation Trust (trust code RBT). Values for this trust are based on incomplete data and should therefore be interpreted with caution.
2. On 1st July 2026, North Bristol NHS Trust (trust code RVJ) was acquired by University Hospitals Bristol and Weston NHS Foundation Trust (trust code RA7). The new organisation is called Bristol NHS Foundation Trust (trust code RA7). In this publication, data are still presented for the two separate organisations. Data will be presented for the new trust at a later date.
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.
