Voluntary, confidential, non-punitive and open. The reporting principles of medical safety adverse events are as follows:

1, voluntary: all departments, departments and individuals in the hospital have the right to voluntarily participate (or withdraw), and providing information to report is the voluntary behavior of informants (departments).

2. Confidentiality: The system keeps the information of the whistleblower and other personnel and departments involved in the report completely confidential. Informants can report anonymously or anonymously through the internet, letters and other forms, and relevant functional departments will keep it strictly confidential.

3. Non-punitive: The content of the report shall not be used as the basis for punishing the whistleblower or others for violating the rules, nor shall it be used as the basis for punishing the personnel and departments involved.

4. Openness: medical safety information is made public in the hospital through relevant functional departments, and medical safety information and its analysis results are shared for the continuous improvement of the quality of hospitals and departments. The public content is limited to the information of the case itself, and does not involve the personal information of the informant and the accused.
