[Review of the initiation and development of the conception of clinical pathway].

Dupont, an American company, used the concept of "pathway" in industry to improve the quality of their products in 1957. In the 1970s, under the pressure of a rise in medical costs, some people realized the concept of the "key pathway" could be used in medicine too. In 1985, the Boston New England Medical Center Hospital (NEMC) succeeded in using the concept of the clinical pathway in medical practice, and afterwards the concept gradually found worldwide application. In 1996, the Fourth Military Medical University in China reported the application of clinical pathway in America. The West China Hospital began to try out the clinical pathway in 1998 and the concept gradually found application in China.
