HistoryThe development of allied health care in the United States began in earnest in the 1930s and early 1940s when education accreditation guidelines were established for clinical pathologists, health information administrators, occupational therapists and radiographers.
Scientific breakthroughs following World War II gave birth to more sophisticated diagnostic tests and treatment techniques. Rising costs also prompted a trend in which an increasing numbers of patients received care in non-hospital settings such as physicians' offices or clinics. Both of these factors created a demand for allied health care professionals.
In 1952 a presidential commission on national health needs sounded the first call for more allied health professionals. Since then allied health care has grown exponentially in terms of both its disciplines and overall workforce.
