Although the timely isolation of patients is an essential intervention to limit spread of drug-resistant bacteria, information about the colonization status is often unavailable or lost when patients are readmitted or transferred between hospitals. Therefore, carriers of drug resistant bacteria are not recognized sufficiently early, and proper and timely isolation precautions are not taken. Consequently, resistant bacteria of public health concerns including vancomycin resistant enterococci (VRE) and methicillin resistant Staphylococcus aureus (MRSA) can spread epidemically. To ensure timely identification and proper isolation of such patients we developed an automatic real-time alert of carriers of drug resistant bacteria.
The aim of this paper is to describe the system, called MiBAlert, and share the initial experiences in connection with an outbreak of VRE in the greater Copenhagen area (the Capital region), Denmark.
We obtained data on cases of VRE from hospitals in Copenhagen during the period when the first version of MiBAlert was implemented and log-data on the use of MiBAlert. Furthermore, a survey was conducted among 88 staff members to investigate their experiences of MiBAlert.
The alert is a tool directed toward healthcare personnel accessing the electronic health record (EHR) and those further involved in the care and treatment of the patient. It is based on a web service using data from the national microbiological database, MiBa. MiBAlert is a real-time electronic non-intrusive alert generated automatically in the header of the EHR each time record is accessed. On February 15, 2015 a pilot version of MiBAlert was launched. All positive tests for VRE throughout 1year were shown with alert status by MiBAlert visible to all medical staff with access to EHR. The alert system was automatically updated directly in the EHR across the five hospitals in the Capital region. We found that the system performed satisfactorily, being operational 24/7 all 135 trial days, apart from 72min, for all the hospitals. Of the staff who responded to the survey, 82% considered that MiBAlert overall improved compliance with isolation precautions regarding VRE-positive patients. We found a marked decline of new patients infected or colonized with VRE concomitant with the implementation of MiBAlert and the survey results.
We found that MiBAlert was a valuable tool in a bundle approach to counter a multiple hospital outbreak of VRE, and that it has a great potential to improve the control of other drug-resistant bacteria.
尽管及时隔离患者是限制耐药菌传播的一项重要干预措施,但当患者再次入院或在医院之间转诊时,关于其定植状态的信息往往无法获取或丢失。因此,耐药菌携带者未能得到足够早的识别,也未采取适当及时的隔离预防措施。结果,包括耐万古霉素肠球菌(VRE)和耐甲氧西林金黄色葡萄球菌(MRSA)在内的引起公共卫生关注的耐药菌得以流行传播。为确保及时识别并适当隔离此类患者,我们开发了一种耐药菌携带者自动实时警报系统。
本文旨在描述名为MiBAlert的系统,并分享在丹麦大哥本哈根地区(首都地区)发生的VRE疫情期间的初步经验。
我们获取了在实施MiBAlert第一版期间哥本哈根各医院的VRE病例数据以及MiBAlert使用情况的日志数据。此外,对88名工作人员进行了一项调查,以了解他们对MiBAlert的使用体验。
该警报是针对访问电子健康记录(EHR)以及进一步参与患者护理和治疗的医护人员的一种工具。它基于一项使用来自国家微生物数据库MiBa数据的网络服务。MiBAlert是一种实时电子非侵入性警报,每次访问记录时都会在EHR的标题中自动生成。2015年2月15日,MiBAlert的一个试验版本上线。在为期1年的时间里,所有VRE阳性检测结果都以警报状态显示,所有有权访问EHR的医护人员都能看到。该警报系统在首都地区的五家医院中直接在EHR中自动更新。我们发现该系统运行令人满意,在全部135个试验日中,除了72分钟外,所有医院均能全天候运行。在回复调查的工作人员中,82%认为MiBAlert总体上提高了对VRE阳性患者隔离预防措施的依从性。我们发现,随着MiBAlert的实施以及调查结果的出现,新感染或定植VRE的患者数量显著下降。
我们发现MiBAlert是应对多家医院VRE疫情综合措施中的一个有价值的工具,并且在改善其他耐药菌控制方面具有巨大潜力。
