Abraham Flexner and the era of medical education reform.

Many forces, including the influential report of Abraham Flexner, acted to reform medical education in the early 20th century. Most physicians were not prepared to adopt recent advances in health care due to their poor medical training. This deficit was recognized in the 20 years before Flexner's report by several organizations, including the Illinois State Board of Health, the American Medical Association, and the Association of American Medical Colleges. Before 1910, each organization had engaged in at least one review of medical schools using defined standards and had identified many of the existing deficits. The number of medical schools already had begun to decrease, dropping from 160 in 1905 to 133 in 1910. Flexner drew heavily, but not exclusively, on the standards for medical education previously developed by other organizations. He visited 155 medical schools in the United States and Canada between December 1908 and April 1910. His 1910 report included a conceptual model of how modern medical education should be conducted and descriptions of each medical school that were explicit in both praise and censure.In the decade following the Flexner Report the number of medical schools decreased from 133 to 85. The actions of state medical licensing boards to deny recognition to poor schools sealed their fate. The remaining schools had higher entrance requirements, longer terms, and better resources. The author describes key factors that contributed to the success of the changes recommended by Flexner and others, and then posits why Flexner is still remembered.
