Summary Hospital-level Mortality Indicator (SHMI)
Published by NHS England · Official source
Update schedule
- Monthly, covering a rolling 12-month period.
Level of detail
- NHS trust
What we show
- The SHMI value — the ratio of deaths that occurred to the number expected given patients' characteristics (1.00 means as many deaths as expected)
- The banding: higher than expected, as expected, or lower than expected
- Observed and expected deaths
Caveats
- The SHMI is NOT a death rate and is NOT a direct measure of the quality of care. It is a screening tool: a high value is a prompt to look more closely, not a conclusion.
- It is adjusted for factors such as age, sex, diagnosis and admission method, but not everything (for example deprivation), so trusts serving different populations aren't perfectly comparable.
- Reported per trust and always labelled 'Trust-wide'. Deaths within 30 days of discharge are included.
