Abstract
Planning for development of a national or regional psychiatrist workforce that is the appropriate size must consider numerous issues. They include the dynamics of workforce distribution, effects of managed care, reduction in potential residency slots, participation of international medical graduates, apathy toward the field of psychiatry, service area variations, and increased interest in allied mental health professions, along with the burgeoning global burden of psychiatric illness. This paper examines the application of two benchmark standards for the number of psychiatrists needed per 100,000 population--the standard developed by the Graduate Medical Education National Advisory Committee and the Average Requirement Benchmark--to the supply of psychiatrists in Georgia in 1996 by county and by health service regions, which are geographical units based on health care utilization patterns of Medicare and Medicaid recipients. Areas with a surplus or deficit of psychiatrists are identified. The findings provide contextual evidence of a surplus of psychiatric physicians in the most populous areas of the state, given a substantial presence of health maintenance organizations. The state's less populated rural areas may potentially benefit from a redistribution of the psychiatrist workforce. The authors recommend continued refinement of models to estimate psychiatric workforce needs and suggest development of a comprehensive model that uses needs-based, demand-based, and benchmarking approaches.
