Metrics for Radiologists in the Era of Value-based Health Care Delivery.

Accelerated by the Patient Protection and Affordable Care Act of 2010, health care delivery in the United States is poised to move from a model that rewards the volume of services provided to one that rewards the value provided by such services. Radiology department operations are currently managed by an array of metrics that assess various departmental missions, but many of these metrics do not measure value. Regulators and other stakeholders also influence what metrics are used to assess medical imaging. Metrics such as the Physician Quality Reporting System are increasingly being linked to financial penalties. In addition, metrics assessing radiology's contribution to cost or outcomes are currently lacking. In fact, radiology is widely viewed as a contributor to health care costs without an adequate understanding of its contribution to downstream cost savings or improvement in patient outcomes. The new value-based system of health care delivery and reimbursement will measure a provider's contribution to reducing costs and improving patient outcomes with the intention of making reimbursement commensurate with adherence to these metrics. The authors describe existing metrics and their application to the practice of radiology, discuss the so-called value equation, and suggest possible metrics that will be useful for demonstrating the value of radiologists' services to their patients.
