Evaluation of health care provider quality is described. Data is obtained, the data including claims data and member data of a member panel of a health care provider, the member panel including patients to which the provider provides health care services. Based on the obtained data, quality scores are determined for the provider across the member panel and across health care quality domains. A composite health provider quality score of the health provider is then determined, where the composite health provider quality score is a composite of the determined quality scores across the member panel and across the multiple health care quality domains. In some embodiments, risk-adjustment is performed for the quality scores, such as risk-adjustment against a peer reference base based on disease categories, patient age, and patient gender.
