Abstract:〔Abstract〕 Objective To discuss how to use frozen platelets legally and legally from the perspective of quality assurance, and to maximize the right of life and health of the blood recipients. Methods The application data of platelet products in hospitals in Jiangxi Province from 2019 to 2021 and the quality monitoring data of monosampling and concentrated platelets in Nanchang region from 2018 to 2021 were analyzed, and the platelet count and other indicators of frozen platelets in Nanchang region were analyzed. Results Platelet blood products in Jiangxi regional hospitals in a total of eight, including apheresis platelet, filter apheresis platelet, concentrated platelet, pooling filter white concentrated platelet, frozen apheresis platelet, frozen apheresis, frozen platelet, frozen concentrated mixed (filter) platelets, frozen platelets including frozen apheresis platelet, frozen apheresis to white platelet, frozen concentrate and frozen concentrated mixed (filter) platelets. The analysis results showed that the platelet count decreased by about 27.3% at the end of preservation, and the concentrated platelet count decreased by about 42.7% at the end of preservation. Conclusion Blood stations and hospitals should use platelet blood products legally and legally, and avoid the use of frozen platelets. In emergency cases, the quality assurance mechanism for the application of frozen platelets must be clarified, including the preparation standards, quality requirements, clinical indications and informed consent principles before use. The province should establish an inter-regional platelet emergency support mechanism and unified emergency coordination.
