Pay-for-performance initiatives that use an efficiency index (EI) to measure physician performance often hinder efforts to reduce overuse of services, a new study suggests. By focusing directly on ways to reduce overuse--without the limitations of EI methodology--physicians could have a more significant impact on improving cost efficiency, according to the study.
The study, “Beyond the Efficiency Index: Finding a Better Way to Reduce Overuse and Increase Efficiency in Physician Care,” was published as a Health Affairs web exclusive (Greene, R.A., et al., May 20, 2008). Researchers for the study suggest an alternative approach to measuring physician performance: determining which interventions are the main drivers of cost for specific conditions, then assessing whether physicians who use these interventions most frequently are obtaining better outcomes or simply generating higher costs. The model was applied to treatment of hypertension as well as fiberoptic laryngoscopy (a procedure that evaluates problems with swallowing). Read the study.
