Through the investigation on tracking review in the ethics committee 3－A－grade hospital in Nanjing, we found that most hospitals had established the tracking review. However, the work to tracking review was not enough, and the records of tracking review were not complete, which needed to be improved. We recommend that the tracking review should be improved, gradually, and the active and passive tracking reviews should be enhanced at the same time. Otherwise, the records of the tracking review process needed to be detailed record. At last, we called on that the research institution of ethics committee should prove enough human resources and material resources for the development of tracking review.
