Star wars, NHS style

摘要

1. Performance of NHS trusts is reported in terms of a star rating 2. The methods used to assess performance in 2002-3 were flawed 3.Use of absolute rather than relative figures for some measures created bias against larger trusts 4. Use of end of quarter figures for outpatient waiting times masked large breaches in some hospitals 5. More statistical rigour is needed to ensure trusts' confidence in the ratings system.
