Comparison of antibiotic-associated diarrhea caused by cefoperazone/sulbactam or piperacillin/tazobactam in neurosurgery patients

OBJECTIVE: To compare the occurrence and prognosis of antibiotic-associated diarrhea (AAD) between patients treated with cefoperazone/sulbactam and piperacillin/tazobactam in the neurosurgery department. METHODS: This study retrospectively analyzed patients who received cefoperazone/sulbactam or piperacillin/tazobactam to prevent or treat hospital-acquired infections in the Department of Neurosurgery of The First Medical Center of Chinese PLA General Hospital between October 2019 and October 2020. For patients with AAD, clinical data, antibiotic usage, the incidence of diarrhea, treatment, and prognosis were collected and analyzed. RESULTS: In total, 356 patients were enrolled, and 65 (18.6%) experienced AAD, 38 patients in the cefoperazone/sulbactam group and 27 patients in the piperacillin/tazobactam group. The AAD rate did not differ between the treatment arms. Conversely, the dosage, intensity, and duration of antibiotic therapy differed between the groups, whereas no differences were noted in the time to the appearance of diarrhea and prognosis. According to regression analysis, the incidence of AAD did not differ between the groups (odds ratio [OR] = 0.85, 95% confidence interval [CI] = 0.46–1.48). CONCLUSION: Cefoperazone/sulbactam or piperacillin/tazobactam can lead to a similar incidence rate of AAD. The combined application of antibiotics and empiric therapy often occurs. The rational use of antibiotics should be improved.
