The quality of medical care depends on the individual physician and on the organization in which he or she works (1-3). In this issue, Mehrotra and colleagues (4) compare 3 types of physician organizations—medical groups, independent practice associations (IPAs), and “hybrids”—on 6 measures of quality. Medical groups are usually defined as organizations in which 3 or more physicians share facilities, staff, and income. Independent practice associations are organizations that contract with health maintenance organizations (HMOs) on behalf of large numbers of medical groups and 1- and 2-physician practices (5-6). Hybrids, a term coined by the investigators, are organizations that consist of a medical group and an IPA.
