Improving Quality Metric Adherence to Minimally Invasive Breast Biopsy among Surgeons Within a Multihospital Health Care System.

Background: Minimally invasive breast biopsy (MIBB) is the procedure of choice for diagnosing breast lesions indeterminate for malignancy. Multihospital health care systems face challenges achieving systemwide adherence to standardized guidelines among surgeons with varying practice patterns. This study tested whether providing individual feedback about surgeons' use of MIBB to diagnose breast malignancies improved quality metric adherence across a large health care organization.
