Five NHS Trusts in England have been categorised as having a ‘higher than expected’ mortality ratio over two years, new analysis shows. During the same period – between July 2010 to June 2012 – 11 Trusts were categorised as having a ‘lower than expected’ ratio, based on Summary Hospital-level Mortality Indicator (SHMI) data.
This analysis features in an experimental report Summary Hospital-level Mortality Indicator (SHMI) – Deaths associated with hospitalisation, England, Experimental Statistics Supplementary Report, July 2010 – June 2012 which is supplementary to the standard quarterly publication of mortality ratios – or SHMI values – for all 142 non-specialist acute Trusts in England. The SHMI compares the actual number of patients who die following hospitalisation at a Trust with the number who would be expected to die, given the characteristics of the patients treated there. It categorises them as ‘as expected’, ‘higher than expected’ or ‘lower than expected’. The Trusts categorised as higher than expected in both the first and latest SHMI publication, which both cover a 12 month period (July 2010 to June 2011 and July 2011 to June 2012) are Colchester Hospital University NHS Foundation Trust, Tameside Hospital NHS Foundation Trust, Blackpool Teaching Hospitals NHS Foundation Trust, Basildon and Thurrock University Hospitals NHS Foundation Trust and East Lancashire Hospitals NHS Trust. Trusts with lower than expected figures include James Paget University Hospitals NHS Foundation Trust; Cambridge University Hospitals NHS Foundation Trust, Royal Free London NHS Foundation Trust, Kingston Hospital NHS Trust, St George’s Healthcare NHS Trust, The Whittington Hospital NHS Trust, Chelsea and Westminster Hospital NHS Foundation Trust, University College London Hospitals NHS Foundation Trust, North West London Hospitals NHS Trust, Imperial College Healthcare NHS Trust, Barnet and Chase Farm Hospitals NHS Trust.
