Objective To provide evidence for establishing a medical risk precaution and monitoring system in China by evidence-based evaluation of the medical risk monitoring and precaution system in Canada, including the current situation and corresponding prevention measures. Method According to the unified search strategy made by our research group, we searched relevant databases and official or government websites. We included articles about medical risk management, medical error and patient safety in Canada. The included articles were classified and the quality was ranked. Results A total of 15 articles were included, among which 10 were official documents (about 2/3) and 5 described research methods (about 1/3), mainly involving medical risk management or evaluation, medical error and patient safety. In 2002, Canada established its National Steering Committee on Patient Safety (NSCPS) and proposed the suggestions to integrate health care resources accross the country, build a patient safety system, and established the Canada Patient Safety Institution (CPSI) to improve patient safety. Canada revised the patient safety management system, collected and issued related information, strengthened doctor-patient communication, developed continuous education for medical staff, practiced the best medical behavior and model and improved lawsuit procedures. These activities have achieved great progress in practice. Conclusions What have been done in Canada will provide a guide for us to establish scientific patient safety system and promote public awareness of patient safety.
