IN 1954-55 93 percent of the professional services in Minnesota's outpatient psychiatric clinics were concentrated in metropolitan areas, and only 7 percent were provided for the 55.7 percent of the State's population residing in nonmetropolitan areas (1). Today, less than 3 years after passage of the Minnesota Community Mental Health Services Act of 1957, outpatient psychiatric care is available to 45 percent of all State residents within their own communities.. As provided in the act, more than half of Minnesota's 87 counties have received State grants-in-aid to esta.blish local mental health centers (2-4). In the evolving Minnesota community mental health program, 12 rural mental health centers serving 45 counties have been approved for State grants-in-aid. These centers serve populations ranging from approximately 116,000 to slightly less than 50,000 residents, and 10 are multicounty units serving from three to eight counties. The distance by road from a center to the farthest village within its service area ranges from 21 to 129 miles, with 47 miles the median distance. These facts illustrate a persistent problem in planning for outpatient mental health facilities: delineation of the geographic area which one center can serve adequately. While guidelines have established the size of the population best served by a full-time mental health team of psychiatrist, psychologist, and social worker, the literature reveals no s.uggestion of the optimum geographic area to be served by either the rural or the urban treatment center. Altman's study (5) of distances traveled for care from general practitioners and medical specialists in western Pennsylvania during 1950-51 offers relevant information, though psychiatric care is not among the categories of medical specialization for which the study presents specific data.. For patients who resided in eiglht counties adjacent to medium-sized metropolitan areas and who used the services of specialists, Altman showed that 59.4 percent lived within 5 miles, while only 11 percent traveled more than 40 miles for care. For the 27 countieis constituting the total studied, he showed a negative relation of 0.74 between average distance traveled and frequency with which specialists' services were obtained. Similarly, the mental health center a,t Crookston, Minn., reported for 1958-59 a negative relation of 0.79 between utiliza,tion and distance. This statistic, like Altman's, does not take into a,ccount those persons who failed to obtain services because of the distances involved.
