简要总结
The combination of vancomycin and piperacillin-tazobactam has been associated with an increased risk of acute kidney injury (AKI) in non-critically ill patient populations, but it is still unknown if this association exists in critically ill patients. The objective of this study is to compare AKI and efficacy of vancomycin plus piperacillin-tazobactam or beta-lactams.
详细描述
The combination of vancomycin and piperacillin-tazobactam has been associated with an increased risk of acute kidney injury (AKI) in non-critically ill patient populations, but limited data regarding this association exists in critically ill patients. The objective of this study is to compare AKI and efficacy of vancomycin plus piperacillin-tazobactam or beta-lactams.
This is a multicenter, retrospective cohort study. Patients from the retrospective cohort will be divided into 2 groups based on the combination regimen received . Patients who meet the inclusion and exclusion criteria will be included in our registry. As a non-intervention study, these information as below will be collected: basic demographics, diagnosis, concomitant nephrotoxic and other antibiotic medications, serum creatine levels, vancomycin concentrations, and indication for antibiotics.

研究组 & 干预措施
vancomycin plus piperacillin/tazobactam
Critically ill patients who received the combination of VAN (vancomycin) and PTZ (piperacillin/tazobactam) for at least 48 hours during an ICU (intensive care unit) admission, had a baseline serum creatinine (Scr) concentration value within 24 hours of hospital admission.The dosage and frequency of VAN and PTZ were adjusted based on clinical practice and patient characteristics. This is an observational study without any intervention.
干预措施: vancomycin plus piperacillin/tazobactam (Drug)
vancomycin plus other beta-lactams
Critically ill patients who received the combination of VAN (vancomycin) and other beta-lactams (cefoperazone/sulbactam, meropenem, imipenem/siastatin, ceftriaxone, ceftazidime, et al) for at least 48 hours during an ICU (intensive care unit) admission, had a baseline serum creatinine (Scr) concentration value within 24 hours of hospital admission.The dosage and frequency of VAN and other beta-lactams were adjusted based on clinical practice and patient characteristics. This is an observational study without any intervention.
