Given the rising burden of healthcare costs, both patients and healthcare purchasers are interested in discerning which physicians deliver quality care. We proposed a methodology to assess physician clinical performance in preventive cardiology care, and determined a benchmark for minimally acceptable performance. We used data on eight evidence-based clinical measures from 811 physicians that completed the American Board of Internal Medicine's Preventive Cardiology Practice Improvement Module[Superscript SM] to form an overall composite score for preventive cardiology care. An expert panel of nine internists/cardiologists skilled in preventive care for cardiovascular disease used an adaptation of the Angoff standard-setting method and the Dunn-Rankin method to create the composite and establish a standard. Physician characteristics were used to examine the validity of the inferences made from the composite scores. The mean composite score was 73.88 % (SD = 11.88 %). Reliability of the composite was high at 0.87. Specialized cardiologists had significantly lower composite scores (P = 0.04), while physicians who reported spending more time in primary, longitudinal, and preventive consultative care had significantly higher scores (P = 0.01), providing some evidence of score validity. The panel established a standard of 47.38 % on the composite measure with high classification accuracy (0.98). Only 2.7 % of the physicians performed below the standard for minimally acceptable preventive cardiovascular disease care. Of those, 64 % (N = 14) were not general cardiologists. Our study presents a psychometrically defensible methodology for assessing physician performance in preventive cardiology while also providing relative feedback with the hope of heightening physician awareness about deficits and improving patient care.
