The Alfalfa-inpatient-CAT assessment model: a thrombotic risk assessment model for inpatient cancer patients

To construct a venous thromboembolism (VTE) risk assessment model specifically for inpatients with cancer. Patients were included according to the inclusion criteria. Univariate and multivariate analyses of all variables were included to develop a VTE risk assessment model applicable to the derivation cohort. Hosmer-Lemeshow test and receiver operating characteristic (ROC) curve were used to test the fit degree and identification validity of the model. The patient data from separate validation cohorts verified the external population. A total of 944 cancer patients were included in this study. Alfalfa-inpatient-CAT model, a risk assessment model for VTE in hospitalized cancer patients, was established, which mainly includes hypertension, surgical history (nearly one month), history of VTE, peripherally inserted central venous catheters (PICC), chemotherapy, PT 0.05, (χ = 8.872, Df = 8). The area under ROC curve was 0.906 [95%CI (0.881-0.930), P
