It is such an attractive idea isn’t it. Pay more to hospitals that save more lives and penalise those that do not. Well that is exactly what the Centers for Medicare and Medicaid Services has been doing in the USA for the past few years with respect to just three medical conditions: myocardial infarction (heart attack), pneumonia, and heart failure. A three-year follow up study has now been reported comparing 2,919 participating hospitals with 1,348 control hospitals – there are a lot of hospitals in the US. The main comparisons: 1) intervention vs. control hospitals; and 2) three targeted conditions vs. other conditions in the intervention hospitals. No effects were observed; intervention hospitals did no better than controls and, across interventions hospitals, the targeted conditions found no better than those that were not targeted. This finding is different to the short, but not long-term, results of a study in England,  though this study was based on payment for compliance with process measures not outcome. The CLAHRC WM Director posits two reasons for the null result in the American study. First, mortality is insensitive to care quality.[4-6] Second, incentives work if ‘agents’ (people targeted by the incentive) think they can influence the outcome. So this is the CLAHRC WM Director’s theory – incentivise specific actions (i.e. process), not outcome, and never use hospital-wide mortality as a quality measure.
