Blood transfusion adverse event management system: construction and application

Abstract

Objective To establish a blood transfusion adverse event management system and apply it to adverse events management, so as to enhance the ability to identify and process reports as well as prevent adverse events. Methods According to the errors during the whole process of blood transfusion, the management information system of blood transfusion adverse events was established, and the data of adverse transfusion reactions and adverse transfusion events from 2020 to 2022 were collected according to the system requirements. The system monitoring data and statistical analysis were used to analyze the causes of errors in each link of blood transfusion, sort the incidence of each department, focus on supervising the departments with high frequency of adverse events, and propose effective rectification. Results The management system counted 51 cases of adverse reactions. The incidence of adverse reactions of plasma (43.1 %, 22/51) was higher than that of red blood cells (39.2 %, 20/51), and the number of allergic reactions was slightly higher than that of febrile non-hemolytic transfusion reaction. Among the 628 cases of adverse transfusion events, blood transport, inbound and storage (TS-A) errors accounted for the highest proportion of 46.2% (290/628), 20.9% (131/628) in post-transfusion disposal and evaluation (TS-G) and 15.8% (99/628) in pre-transfusion evaluation and transfusion application (TS-B). TS-A12 accounted for 63.8 % (185/290) in TS-A errors, which was mainly due to plasma leakage caused by extrusion during transport and the expiration of red blood cells caused by insufficient blood inventory management. TS-B errors mainly focus on the failure to fully assess the bleeding tendency of patients before surgical system surgery, resulting in no or insufficient preoperative blood preparation. Most of the TS-G errors were unqualified medical record. Conclusion Blood transfusion adverse event management system can help to identify and prevent the occurrence or recurrence of adverse events, formulate targeted rectification and preventive measures, and improve the haemovigilance ability.
