Objective: To evaluate evidence from American medical risk monitoring and precaution system (AMRMPS) which may affect the construction of Chinese medical risk monitoring and precaution system (CMRMPS). Methods: We searched relevant databases and Internet resources to identify literature on AMRMPS, medical errors, and patient safety. We used the quality evaluation system for medical risk management literature to extract and evaluate data. Results: In 1999, a report from the Institute of Medicine (IOM) not only showed the severity and cause of medical errors in America but also gave the solution of it. In 2000, the Quality Interagency Coordination Task Force (QuIC) was appointed to assess the IOM report and take specific steps to improve AMRMPS. After 5 years, a well-developed medical risk management system was established with the improvement in the public awareness of medical errors, patient safety, performance criteria of medical safety, information technology and error reporting system. There was still some weakness of this system in risk precaution and prevention. Conclusion: The experience from AMRMPS can be used to establish the CMRMPS. Firstly, we should disseminate and strengthen the awareness of medical risk and patient safety in public. Secondly, we should establish hospital audit system which includes auditing of medical staff and course of medical risk in continuing and academic education. Thirdly, we should develop regulations and guidelines on health care, medical purchase and drug supply which will benefit in management of regular work. Fourthly, we should develop computer information system for hospital which will regulate the management without the disturbance from human. Lastly, we should emphasize outcome evaluations and strive for perfection during the process.
