Abstract:With the rapid development of biomedical science and technology in China, the number of clinical research projects is increasing rapidly, which is accompanied by ethical challenges. In recent years, a number of regional ethics committees have been established in China, and some experience has been gained in regional ethical review, but there is a certain difficulty in implementing it. In response to the difficulties in regional ethical review, the ethical cooperative review mode of medical union with the leading units as the core has been established based on the experience of foreign regional ethical review and the characteristics of the medical consortium structures that have been widely established in the county-level hospitals and prefecture level tertiary hospitals in Jiangsu region. It is expected to give full play to the flexible advantages of regional ethics committees by radiating and promoting the ethical review ability of medical union.
