These indicators are 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.
COVID-19 activity is included in the SHMI if the discharge date is on or after 1 September 2021.
Contextual indicators on the number of provider spells which are related to COVID-19 and on the number of provider spells as a percentage of pre-pandemic activity (January 2019 – December 2019) are produced to support the interpretation of the SHMI.
These indicators are being published as official statistics in development. Official statistics in development are published in order to involve users and stakeholders in their development and as a means to build in quality at an early stage.
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. Royal Surrey County Hospital NHS Foundation Trust (trust code RA2) has a high percentage of records with no data for secondary diagnoses. This is having a large impact on this trust’s data and values for this trust should therefore be interpreted with caution.
5. There is a high percentage of invalid diagnosis codes for Chesterfield Royal Hospital NHS Foundation Trust (trust code RFS), East Lancashire Hospitals NHS Trust (trust code RXR), Harrogate and District NHS Foundation Trust (trust code RCD), Portsmouth Hospitals University NHS Trust (trust code RHU), and University Hospitals Plymouth NHS Trust (trust code RK9). Values for these trusts should therefore be interpreted with caution.
6. 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.
