ABSTRACT OBJECTIVE To explore the predictive factors of cefoperazone/sulbactam-induced thrombocytopenia in adult
inpatients, and to establish and validate the nomogram prediction model. METHODS Data of adult inpatients treated with
cefoperazone/sulbactam in Xi’an Central Hospital from Jun. 30th, 2021 to Jun. 30th, 2023 were retrospectively collected. The
training set and internal validation set were randomly constructed in a 7∶3 ratio. Singler factor and multifactor Logistic regression
analysis were used to screen the independent predictors of cefoperazone/sulbactam-induced thrombocytopenia. The nomogram was
drawn by using “RMS” of R 4.0.3 software, and the predictive performance of the model was evaluated by the receiver operating
characteristic curve and C-index curve. Hosmer-Lemeshow goodness-of-fit test was used to evaluate the calibration degree of the
model. Using the same standard, the clinical data of hospitalized patients receiving cefoperazone/sulbactam in Xi’an First Hospital
in the same period were collected for external validation of the nomogram prediction model. RESULTS A total of 1 045 patients in
Xi’an Central Hospital were included in this study, among which 67 patients suffered from cefoperazone/sulbactam-induced
thrombocytopenia, with an incidence of 6.41%. After the false
