Some generalist physicians whose training prepared them for primary care practice increasingly practice in a facility (eg, hospitals, nursing homes); however, whether this trend was accompanied by a complimentary rise in generalist physicians who focused their practice on office-based care is unknown.Our objective in this study was to examine trends in the prevalence of generalist physicians and physician groups that practice in a single setting.This was a retrospective cross-sectional study of generalist physicians trained in family medicine, internal medicine, or geriatrics. We used 2014-2017 billing data for Medicare fee-for-service beneficiaries to measure the proportion of all patient visits made by physicians in the following care settings: office, outpatient hospital department, inpatient hospital, and other sites.From 2014 to 2017, the proportion of generalist physicians who narrowed their practice to a single setting increased by 6.69% (from 62.80% to 67.00%, p for trendlt;0.001). In 2017, 4.63% of physician groups included more than 1 type of setting-based physicians.Generalist physicians treating older adults increasingly narrowed their practice focus to a single type of health care setting. This trend was not accompanied by growth among physician groups that included different types of setting-based physicians. Further evaluation of the consequences of these trends on the fragmentation of primary care delivery across different health care settings and primary care outcomes is needed. |
