The effects of physician in-migration to rural Colorado (1992 to 1995).

This paper reports the results of an analysis of the American Medical Association Masterfile. The purpose of this study was to examine changes in health care accessibility in rural Colorado from 1992 to 1995, and to describe the pattern of in-migration of physicians to nonmetropolitan statistical area counties of the state during that period. The number of direct patient care providers increased from 532 to 700 (31.6%) during the three-year period vs. a growth of 11.2 percent in the general population of nonmetropolitan statistical area counties. Of the 700 physicians serving residents of Colorado's 52 rural counties, 308 (44%) had been practicing in their community since 1992. The rate of departure from nonmetropolitan statistical area practice sites in 1992 was 26.4 percent (140 of 532). Physicians new to their rural practice locations were younger and proportionally more female, but they were similar in primary medical specialty to doctors who had remained in their 1992 sites. Population to physician and to primary care physician ratios were much more favorable for 1995 than for 1992. Accessibility to care was most improved in counties with fewer than 10,000 inhabitants.
