What is the hospital mortality (SHMI) for Calderdale and Huddersfield NHS Foundation Trust?
For November 2024 to October 2025, Calderdale and Huddersfield NHS Foundation Trust had an NHS SHMI of 1.180 (Gera Hospital Mortality Index 118.0), banded "higher than expected": 2,490 deaths observed against 2,110 expected — 18.0% above the national expectation. This is real NHS open data and a "smoke alarm", not a measure of care quality.
What “higher than expected” means here
The number of deaths was higher than expected given the patients treated. NHS England treats this as a "smoke alarm" for further investigation, not as evidence of poor care.
The SHMI is NOT a measure of quality of care. NHS England is explicit that a higher-than-expected SHMI should be treated as a "smoke alarm" — a prompt to investigate, not evidence of poor care — and that an "as expected" or "lower than expected" value should not be read as proof of good care. Many factors outside a hospital’s control (local population health, the prevalence of palliative-care coding, deaths in hospices) affect the figure.
An index of 118.0 means Calderdale and Huddersfield NHS Foundation Trust was 18.0% above the national expectation for this period. The index is the official SHMI (1.180) multiplied by 100; every figure is the real published NHS number, and the method is set out in the methodology.

In plain English
Over November 2024 to October 2025, Calderdale and Huddersfield NHS Foundation Trust recorded 2,490 deaths in hospital or within 30 days of discharge, against 2,110 the NHS model expected given the patients it treated across 50,705 completed stays. That is 380 more deaths than expected — a SHMI of 1.180, which the NHS bands as higher than expected. Because the expected figure already adjusts for how sick and how old the patients were, the comparison is with what would be typical for a similar case mix in England — but it still does not measure the quality or safety of care.
