无证行医(即非法行医)是指未取得《医疗机构执业许可证》从事医疗执业的活动。无证行医行为不但严重危害人民群众的身心健康和生命安全,而且扰乱了正常的医疗市场秩序,影响依法治国政策落实,其社会危害较大,群众反应强烈。由于西方发达国家建立了较完备的法律法规和完善的医疗保障制度,非法行医现象在西方发达国家很少。一 Unlicensed practice (that is, illegal medical practice) refers to the medical institutions that have not obtained a medical license to engage in medical practice activities. The practice of operating without a license not only seriously endangers the people’s physical and mental health and life safety, but also disrupts the normal medical market order and affects the implementation of the policy of governing the country by law. Its social harms and the mass reaction are strong. As western developed countries have established relatively complete laws and regulations and a sound medical insurance system, the phenomenon of illegal medical practice is rare in western developed countries. one
