The Impact of Risk Management Standards on Patient Safety: The Determinants of MRSA Infections in Acute NHS Hospitals, 2001–08*
研究了英国NHS医院风险管理标准对MRSA感染率的影响，发现达到更高标准的医院感染率下降，且这种关系可能是因果性的。
Abstract We study a key part of National Health Service (NHS) policy to ensure high‐quality health care: failure to supply such care cost the NHS £787m in clinical negligence payouts during 2009–10. The NHS uses risk management standards to incentivize care, and we examine their effects on methicillin resistant Staphylococcus aureus (MRSA) infections. Using a specially assembled data set, our GMM results suggest that improvements in the risk management standards attained by some hospitals are correlated with reductions in their MRSA infection rates. Moreover, the exogeneity of this relationship cannot be rejected for higher risk management levels, suggesting attainment of higher standards was instrumental in reducing infection rates.
