Those physicians who are not classified as primary care practitioners are classified as specialists. In 2001, there were more active licensed specialist physicians (5,405) than primary care physicians (4,349) in Arizona. However, there were greater increases in the number and percentage of primary care physicians (+528 and 14%) than specialist physicians (+45 and 0.8%) during the five-year period from 1997 to 2001. Figure 15 and Table 8 describe the specialist physician five-year trends. The number of allopathic specialist physicians decreased by 18 (-0.4%) while the number of osteopathic specialist physicians increased by 63 (18%) during the same period (Table 9 and Table 10). However, ninety-two percent of all specialists are allopathic physicians. In 1998, Arizona had 127 active specialist physicians per 100,000 population which was fewer than the Region IX average of 131 and the national average of 139¹.

During the period from 1997 to 2001, there was a decrease in Arizona’s ratio of specialist physicians to 100,000 population from 116.7 to 101.9 (Figure 16). The two urban counties (136.5 to 116.8) had greater decreases than the two rural-urban counties (84.4 to 80.3). However, the 11 rural-rural counties showed increases in the specialist physician ratio (42.0 to 45.4).

The number and percentage of active licensed specialist physicians also decreased in the two urban counties (-66 and -1%) during this same period of time. Pima County (-54 and -4%) had greater decreases than Maricopa County (-12 and -0.3%). The 11 rural-rural counties showed overall increases (+90 and 26%) which were greater than those in the two rural-urban counties (+21 and 10%). La Paz County also showed decreases in the number of specialist physicians (changing from 6 to 3, with a -50% net result). There were no changes in Greenlee and Santa Cruz Counties. The greatest percentage increases occurred in Apache (+6 and 100%) and Gila (+15 and 88%) counties. The remaining counties also showed increases.
