BACKGROUND Preprescription authorization (PPA) and postprescription review with feedback (PPRF) were successively implemented in 2012 and 2016 in our 1500-bed hospital. AIM The impact of PPA and PPRF on carbapenems use and resistance levels of Pseudomonas aeruginosa was assessed in three intensive care units (ICUs). METHODS Carbapenems use (in DDDs/1000 occupied bed-days) and resistance of P. aeruginosa (percentage of non-susceptible (I+R) isolates to imipenem and/or meropenem) were analysed using a controlled interrupted time-series method. Two periods were compared: 2012-2015 (PPA) and 2016-2017 (PPA+PPRF). Models were adjusted on the annual incidence of extended-spectrum β-lactamase-producing enterobacteriacae. FINDINGS Carbapenem use was stable over the PPA period in all ICUs, with a significant change of slope over the PPA+PPRF period only in ICU1 (β2 = -12.8, 95% confidence interval (CI) = -19.5 to -6.1). There was a switch from imipenem to meropenem during the PPA period in all three units. Resistances of P. aeruginosa were stable over the study period in ICU1 and ICU2, and significantly decreased over the PPA+PPRF period in ICU3 (β2 = -0.18, CI = -0.3 to -0.03). CONCLUSION In real-life conditions and with the same antimicrobial stewardship programme (AMSP) led by a single team, the impact of PPRF was heterogeneous between ICUs. Factors driving the impact of AMSPs should be further assessed in comparable settings through real-life data, to target where they could prove cost-effective.

抗菌药物管理计划对三个重症监护病房的可变影响:2012-2017年监测数据的时间序列分析。

背景技术处方授权(PPA)和带有反馈的处方后审核(PPRF)分别于2012年和2016年在我们拥有1500张床位的医院中实施。目的在三个重症监护病房(ICU)中评估了PPA和PPRF对碳青霉烯的使用和铜绿假单胞菌耐药水平的影响。方法采用控制间断时间序列方法分析了碳青霉烯类药物的使用(以DDDs / 1000个就寝日数为单位)和铜绿假单胞菌的耐药性(非敏感性(I + R)分离株对亚胺培南和/或美洛培南的百分比)。比较了两个时期:2012-2015(PPA)和2016-2017(PPA + PPRF)。根据产生大光谱β-内酰胺酶的肠杆菌的年发病率对模型进行了调整。研究结果表明,在所有ICU中,PPA期间碳青霉烯类药物的使用稳定,仅在ICU1中,PPA + PPRF期间的斜率有显着变化(β2= -12.8,95%置信区间(CI)= -19.5至-6.1)。在所有三个单元中,PPA期间均从亚胺培南转向美罗培南。在研究期间,铜绿假单胞菌的抗性在ICU1和ICU2中稳定,在ICU3中的PPA + PPRF期间显着降低(β2= -0.18,CI = -0.3至-0.03)。结论在现实生活中,在由一个小组领导的相同的抗菌素管理计划(AMSP)下,PPRF的影响在ICU之间是异质的。应在可比较的环境中通过实际数据进一步评估驱动AMSP产生影响的因素,以定位可证明具有成本效益的地方。在所有三个单元中,PPA期间均从亚胺培南转向美罗培南。在研究期间,铜绿假单胞菌的抗性在ICU1和ICU2中稳定,在ICU3中的PPA + PPRF期间显着降低(β2= -0.18,CI = -0.3至-0.03)。结论在现实生活中,在由一个小组领导的相同的抗菌素管理计划(AMSP)下,PPRF的影响在ICU之间是异质的。应在可比较的环境中通过实际数据进一步评估驱动AMSP产生影响的因素,以定位可证明具有成本效益的地方。在所有三个单元中,PPA期间均从亚胺培南转向美罗培南。在研究期间,铜绿假单胞菌的抗性在ICU1和ICU2中稳定,在ICU3中的PPA + PPRF期间显着降低(β2= -0.18,CI = -0.3至-0.03)。结论在现实生活中,并且由一个小组领导的相同的抗菌素管理计划(AMSP),PPRF的影响在ICU之间是异质的。应在可比较的环境中通过实际数据进一步评估驱动AMSP产生影响的因素,以定位可证明具有成本效益的地方。结论在现实生活中,在由一个小组领导的相同的抗菌素管理计划(AMSP)下,PPRF的影响在ICU之间是异质的。应在可比较的环境中通过实际数据进一步评估驱动AMSP产生影响的因素,以定位可证明具有成本效益的地方。结论在现实生活中,在由一个小组领导的相同的抗菌素管理计划(AMSP)下,PPRF的影响在ICU之间是异质的。应在可比较的环境中通过实际数据进一步评估驱动AMSP产生影响的因素,以定位可证明具有成本效益的地方。
