It was not until the late 19th to late 20th century, when medical education in the U.S.
improved and implemented a partnership with hospitals to implement a practical medical education in the training of new
physicians.
Nowadays, in the U.S. there is a hospital-based training for physicians and this has led to producing more specialists than primary care physicians (Shi & Sing, 2015, p. 131). For teaching hospitals, the principal source of funding was the Medicare program and because of the high ratio between current practicing specialists and primary care physicians, medical education is being refocused in patient-centered cared instead of acute care. Since specialization in physicians was growing, hospitals started to play a critical role in medical education and research, one example is the Johns Hopkins Hospital medical school, that opened on 1893, that combined clinical practice with teaching (Shi & Singh, 2015, p. 295). Also, hospitals became the center of medical research in adjunction with medical schools, medical researchers work in close contact with hospitals. With the ongoing discovery of unknown diseases or medical complications, it is very important that medical researchers use the available data in hospitals to create novel treatments and improve current procedures for the safety and health promotion of the patients. In the past the U.S. was lagged behind Europe in medical training and medical research but in the mid 1800’s the field of medical research started to growth in the U.S. Nowadays the Association of American Medical Colleges (AMMC), founded in 1876, set the minimum standards for medical education and the American Medical Association (AMA), formed in 1847, regulates medical licensing (Shi & Singh, 2015, p. 92).
