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 Torbay and South Devon NHS Foundation Trust (trust code RA9) and York and Scarborough Teaching Hospitals NHS Foundation Trust (trust code RCB). Values for these trusts are based on incomplete data and should therefore be interpreted with caution.
2. There are variations between trusts in the recording of same day emergency care (SDEC). Where trusts are submitting SDEC activity as part of the Outpatient dataset or Emergency Care Data Set (ECDS) rather than the Admitted Patient Care (APC) dataset or are recording this activity as day cases within the APC data, these records will not be included in the SHMI. Trusts with SDEC activity removed from the SHMI data have seen an increase in their SHMI value. As all trusts are expected to transition to recording SDEC activity as admitted patients, the data will become more comparable over time and the impact on the SHMI will reduce.
3. 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). The new organisation structure is reflected from this publication onwards.
