The paper reviews the background and current situation of medical disputes and puts forward the concept of the reaction chain of medical disputes in view of their high occurrence rate and the difficulty in handling them. It discusses the framework, chief content, basic principles and major features of the reaction chain of medical disputes and argues that as a commonly used tool for handling medical disputes, the reaction chain renders it possible to check from the angje of the interests of the patients whether each party involved in the dispute has fulfilled its duties. Intended to improve the professional ethics of the physicians and the quality of medical care and calling on the patients to rebuild their confidence in the physicians, the reaction chain indicates that it is necessary to scientifically analyze the entire process and various influencing factors of medical disputes and bring into play the advantages of integration so as to successfully resolve medical disputes.
