Blue Cross Blue Shield of Massachusetts (BCBSMA), a large commercial health insurer, is using financial incentives to advance equity of care by patient race and ethnicity. Understanding experiences of this payer and its contracted physician groups can inform efforts elsewhere. We qualitatively assess physician groups' barriers and facilitators of planning and implementing BCBSMA's financial incentives to improve equity of ambulatory care quality by patient race and ethnicity. Key informant interviews (n = 44) of the physician group, BCBSMA, and external stakeholders were conducted, equity initiative meetings were observed, and documents were analyzed to identify barriers and facilitators of designing and preparing for financial incentives to advance racial equity. Physician group experiences of preparing for and responding to financial incentives for equity improvement were assessed. Analyses revealed 1) the central importance of valid and reliable equity performance measurement and carefully designed equity improvement incentives for physician group buy-in, 2) that prior to implementing financial incentives for equity improvement, physician groups needed to improve their quality management systems and the accuracy and completeness of patient race and ethnicity data, and 3) physician groups' populations served, baseline maturity of quality management systems, and efforts to assess and address patients' social risk factors were central to consider to plan for physician group financial incentives to improve racial equity. Given the major infrastructure investments and organizational change management resources required of physician groups to participate in a financial incentive program designed to reward equity improvement, alignment of equity measurement and performance requirements across payers would facilitate physician groups' engagement in efforts to improve quality of care for racial and ethnic minority patients.
