Characteristics and Influencing Factors of Coagulation Dysfunction Caused by Cefoperazone/Sulbactam.

To evaluate associations between patient characteristics and cefoperazone/sulbactam-associated coagulation dysfunction.Retrospective analysis was performed on 821 cases of bacterial infection treated with cefoperazone/sulbactam for more than three days in the Sixth Hospital of Wuhan, Affiliated Hospital of Jianghan University, from January 2018 to June 2022. The patients were divided into normal coagulation function group (NCFG) (781 cases) and abnormal coagulation function group (ACFG) (40 cases) according to their coagulation function. Univariate and multivariate logistic regression analysis used the general data of the two groups of patients to investigate the risk factors of abnormal coagulation function caused by cefoperazone/sulbactam.The incidence of abnormal coagulation function caused by cefoperazone/sulbactam was 4.87% (40/821). There was no significant difference in gender, body mass index (BMI), marriage, educational background, and concurrent medical conditions between the two groups (all P > .05). The patients in ACFG were older, the dosage and duration of cefoperazone/sulbactam were more prolonged, and the liver and kidney functions were more abnormal than those in NCFG, with significant differences (all P < .05). Univariate and multivariate logistic regression analysis showed that age (≥ 65 years old) (OR=1.293, 95%CI:0.897-1.287), duration of therapy (>10d) (OR=1.765, 95%CI:1.052-3.761), daily dosage (>6g) (OR=3.291, 95%CI:1.732-6.871), aspartate aminotransferase (AST) (≥ 23.98U/L) (OR=3.281, 95%CI:1.009-6.981), alanine aminotransferase (ALT) (≥ 24.03U/L) (OR=2.109, 95%CI:1.276-3.298), and serum creatinine (SCR) (>107 μ mol/L) (OR=2.716, 95%CI:1.023-4.398), prothrombin time (PT) (≥ 13.9U/L) (OR=1.571, 95%CI:1.287-1.945) were the risk factors (P < .05).Elderly patients, time of use, daily dose of use, liver and kidney function, and PT are the risk factors of cefoperazone/sulbactam leading to abnormal coagulation function.
