Mortality (SHMI)
The Summary Hospital-level Mortality Indicator compares the number of people who die after care at this trust with the number expected, given how ill the patients were. Rolling 12 months to August 2025. This figure is for London North West University Healthcare NHS Trust, which runs this hospital.
NHS Digital, Accredited Official Statistic, Open Government Licence v3.0, retrieved 2026-10-25. The SHMI is not a measure of the quality of care and a “higher than expected” band is a flag for further investigation, not a judgement. It must not be used to rank trusts. It does not include deaths of patients receiving palliative care where that is coded.
