Patient days and days present were compared to directly measured person time to quantify how choice of different denominator metrics may affect antimicrobial use rates. Overall, days present were approximately one-third higher than patient days. This difference varied among hospitals and units and was influenced by short length of stay.Infect Control Hosp Epidemiol 2018;39:612-615.
将实际患者日和报告患者日进行对比,以直接衡量患者人时来量化不同分母指标的选择如何影响抗菌药物使用率。总体而言,报告患者日比实际患者日高约三分之一。这种差异在不同医院和科室之间有所不同,受到住院时间短的影响。感染控制与医院流行病学 2018;39:612-615.
