There is a national shortage of psychiatrists, and according to nationally available data, it is projected to get worse. Locum tenens psychiatry and telepsychiatry are two ways to fill the shortages of psychiatric providers that exist in many areas in the United States. Employment and salary data in these areas can be used to illuminate current trends and anticipate future solutions to the problem of increasing demand for, and decreasing supply of, psychiatrists in the United States.A search was conducted of the literature and relevant Web sites, including PubMed, Google Scholar, and www.google.com , as well as information obtained from locum tenens and telepsychiatry organizations.There is a dearth of data on the use of locum tenens in the field of psychiatry, with little available prior to 2000 and few published studies since then. The majority of the data available are survey data from commercial entities. These data show trends toward increasing demand for psychiatry along with increasing salaries and indicate the utilization of telepsychiatry and locum tenens telepsychiatry is increasing. The published academic data that are available show that although locum tenens psychiatry is slightly inferior to routine psychiatric care, telepsychiatry is generally equivalent to face-to-face care.One can anticipate that as the national shortage of psychiatrists is expected to accelerate, use of both locum tenens and telepsychiatry may also continue to increase. Telepsychiatry offers several possible advantages, including lower cost, longer-term services, quality of care, and models that can extend psychiatric services. If current trends continue, systems that demand face-to-face psychiatry may find themselves paying higher fees for locum tenens psychiatrists, whereas others may employ psychiatrists more efficiently with telepsychiatry.
