1 results about "Transfusion management" patented technology

The application discloses a risk assessment system for cross matching difficulty, and relates to the technical field of clinical medical examination and blood transfusion management. The system comprises a data input module, a risk calculation module, a risk stratification module and a result output and suggestion module. The data input module obtains key information of a patient, including irregular red blood cell antibody screening results, multiple myeloma diagnosis, hematology department medical history, age of 60 years or older, pregnancy-related disease state and blood type identification difficulty; the risk calculation module adopts a preset scoring algorithm to assign weights to each factor and calculate a total risk score; the risk stratification module divides the patient into three grades of low risk, medium risk and high risk; and the result output module provides a differentiated clinical management path corresponding to the risk grade. The application realizes early warning of cross matching difficulty through quantitative assessment, can optimize the efficiency of the blood transfusion process and reduce clinical risk, has good prediction performance (AUC=0.819) and a high negative predictive value (93.7%).
