Analysis and commentary: A road map for improving the performance of performance measures

The desire to improve the quality of health care has prompted the increased use of performance measures. These measures examine the outcomes of interventions for evidence of improved health and are used to hold providers accountable for the quality of health care.

This article discusses the current impasse in the field of quality measurement and what is needed to overcome this deadlock.
