Abstract Objective: To construct and validate a nomogram that can be used to predict platelet transfusion refractoriness in patients who received platelet transfusions. Methods: A total of 174 patients who received platelet transfusions were selected from the Second Affiliated Hospital & Yuying Children’s Hospital of Wenzhou Medical University from January 2019 to December 2019. Among 174 patients, 46 (26.4%) were platelet transfusion refractoriness. Pertinent clinical data were collected including patient age, gender, multiple pregnancies,active bleeding, skin and mucous membrane bleeding, splenomegaly, fever, ABO blood group, number of platelet transfusions, platelet antibody and platelet count. Multivariate logistic regression was used to screen independent factors and to construct the nomogram. Results: Multivariate logistic regression indicated that female (OR=2.43,95%CI=1.08-5.44, P=0.0310), platelet antibody (OR=4.46, 95%CI=1.11-17.85, P=0.035), infection (OR=2.42,95%CI=1.03-5.71, P=0.042), splenomegaly (OR=2.14, 95%CI=1.01-5.92, P=0.045), infusion times (OR=4.90,95%CI=2.10-11.42, P=0.002) were associated with higher odds of platelet transfusion refractoriness. Afterwards,the above variables were incorporated into the nomogram. Bootstrap test (Bootstrap resampling times=500),used for internal validation, revealed that the AUC was 0.858. Conclusion: The constructed nomogram could potentially predict platelet transfusion refractoriness in patients who received platelet transfusion.
