Summary
This publication of the SHMI relates to discharges in the reporting period April 2015 to March 2016.
The SHMI is the ratio between the actual number of patients who die following hospitalisation at the trust and the number that would be expected to die on the basis of average England figures, given the characteristics of the patients treated there.
It covers all deaths reported of patients who were admitted to non-specialist acute trusts in England and either die while in hospital or within 30 days of discharge.
To help users of the data understand the SHMI, trusts have been categorised into bandings indicating whether a trust's SHMI is 'higher than expected', 'as expected' or 'lower than expected'.
Further background information and supporting documents, including information on how to interpret the SHMI, are available on the SHMI homepage (see Related Links).
Key Facts
For the 136 trusts included in the SHMI from 1 April 2015 to 31 March 2016:
• There were approximately 8.8 million finished provider spells, from which 283,000 deaths were recorded either while in hospital or within 30 days of discharge. This includes deaths from other causes as well as deaths related to the reason for the hospital admission.
• 16 trusts had a 'higher than expected' SHMI. Of these 16 trusts, 8 also had a 'higher than expected' SHMI for the same period in the previous year.
• 104 trusts had an 'as expected' SHMI.
• 16 trusts had a 'lower than expected' SHMI. Of these 16 trusts, 9 also had a 'lower than expected' SHMI for the same period in the previous year.
Notes:
1. There is a shortfall in the number of records in the Hospital Episode Statistics (HES) data for discharges in the reporting period April 2015 - March 2016 for Royal Berkshire NHS Foundation Trust (provider code RHW). There are duplicate records in the HES data for Chelsea and Westminster Hospital NHS Foundation Trust (provider code RQM) for the same reporting period. Further details are provided in the HES data quality notes (see Related Links). This has a negligible impact on the SHMI at national level. However, the SHMI values for these trusts should be interpreted with caution.
2. Further information on data quality can be found in Appendix B: Background Quality Report of the SHMI quarterly report, which can be downloaded from the 'Resources' section of this page.
