This was a prospective study to determine if pharmacokinetic/pharmacodynamic (PK/PD)-based antibiotic dosing software aids in achieving concentration targets in critically ill patients receiving cefepime ( = 10), meropenem ( = 20), or piperacillin-tazobactam ( = 19). Antibiotic calculator doses targeting a >90% probability of target attainment (PTA) differed from package insert doses for 22.4% (11/49) of patients. Target attainment was achieved for 98% of patients (48/49). A PK/PD-based antibiotic dosing calculator provides beta-lactam doses with a high PTA in critically ill patients.
这是一项前瞻性研究，旨在确定基于药代动力学/药效学（PK/PD）的抗生素剂量计算软件是否有助于达到接受头孢吡肟（= 10）、美罗培南（= 20）或哌拉西林他唑巴坦（= 19）治疗的危重症患者的浓度目标。抗生素计算器剂量的目标是达到 >90%的目标命中率（PTA），与 22.4%（11/49）的患者的用药说明书剂量不同。98%的患者（48/49）达到了目标。基于 PK/PD 的抗生素剂量计算为危重症患者提供了具有高 PTA 的β-内酰胺剂量。
