The duration of eXDR carriage depends on several factors that might be difficult to recover. We aim to assess the duration of eXDR carriage by using a simple to recover parameter: the number of consecutive negative screening. 131 eXDR carriers (51 VRE and 80 CPE) were included. The number of consecutive negative screenings was strongly associated with eXDR clearance. All patients displaying at least three negative screenings over a seven-month period were never screened positive thereafter. Taking into account the number of negative screenings as a part of a case-by-case risk assessment would be helpful for the decision to maintain or lift eXDR-focused precautions.

无症状携带广泛耐药的细菌（eXDR），这是评估自发清除的一种简单方法。

eXDR传送的持续时间取决于可能难以恢复的几个因素。我们旨在通过使用一个简单的恢复参数（即连续阴性筛查的次数）来评估eXDR运输的持续时间。其中包括131个eXDR载体（51 VRE和80 CPE）。连续阴性筛查的次数与eXDR清除率密切相关。此后在7个月内显示至少3次阴性筛查的所有患者均从未筛查出阳性。在个案风险评估中考虑负面筛查的次数将有助于决定维持或取消以eXDR为重点的预防措施。
