Recently, the authors have witnessed a renewed interest in research aimed at describing disparities in health care. However, while they are learning much about where differences lie, the authors are barely out of the driveway and on the road to explaining why disparities exist, nor do they know how to eliminate them. In addition to the handful of studies that have looked at managed care as a mechanism for increasing access to preventive care services, health services researchers are beginning to examine the influence of managed care on disparities in health care quality. Repeatedly, these studies conclude that minorities (especially black patients and patients of Asian/Pacific Islander descent) receive less access to and poorer quality care.
