This indicator is designed to accompany the SHMI publication.
This publication was updated on 9th August 2024. Data for Royal Surrey County Hospital NHS Foundation Trust (trust code RA2) has been suppressed from publication. This trust had submitted in error a high percentage of records with no secondary care diagnosis codes, this has made their SHMI values highly misleading. They have corrected the data at source, and this is expected to be reflected in the November 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.
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. Data for Royal Surrey County Hospital NHS Foundation Trust (trust code RA2) has been suppressed from publication. This trust had submitted in error a high percentage of records with no secondary care diagnosis codes, this has made their SHMI values highly misleading.
2. There is a shortfall in the number of records for East Lancashire Hospitals NHS Trust (trust code RXR), Harrogate and District NHS Foundation Trust (trust code RCD), and Northern Lincolnshire and Goole NHS Foundation Trust (trust code RJL). Values for these trusts are based on incomplete data and should therefore be interpreted with caution.
3. Guy’s and St Thomas’ NHS Foundation Trust (trust code RJ1) has a high percentage of records with missing data for the Sex field. Values for this trust should therefore be interpreted with caution.
4. 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 SHMI background quality report.
