Introduction
The Medical Ethics Committee of The University of Hong Kong - Shenzhen Hospital (HKU - SZH) was formally established in March 2013. Its purpose is to supervise all diagnosis, treatment and research carried out within the hospital, and its mission is to protect the rights and interests, safety, and health of patients and research participants from an ethical perspective. To standardize the management and operation of the Ethics Committee, the hospital drew on the management model of the Research Ethics Committee of the Hong Kong West Cluster under the Hospital Authority of Hong Kong, and formally issued the Standard Operating Procedures (SOP) for the Medical Ethics Committee of HKU-SZH on September 22, 2014, which has now been updated to the 6th edition. This SOP formulates detailed operational guidelines for the organizational management and operation of the Medical Ethics Committee. The Medical Ethics Committee of HKU - SZH is a first-tier committee of the hospital. It holds two plenary meetings every year to listen to the reports of each second-tier committee and discuss ethics-related issues. Based on functional responsibilities, the Medical Ethics Committee has established several second-tier ethics committees under it, including Research Ethics Committee, Clinical Trial Ethics Committee, Clinical Technology Ethics Committee, Prenatal Diagnosis Ethics Committee, Human Organ Transplant Ethics Committee, and Stem Cell Clinical Research Ethics Committee. Chairmen and vice chairmen are appointed to each second-tier committee, which is responsible for reviewing ethics-related projects in their respective professional fields. In July 2025, the hospital adjusted the organizational structure of its ethics committee system, and Reproductive Medicine Ethics Committee was designated as an independent first-tier committee.
