Carbapenemase-producing Enterobacterales and vancomycin-resistant Enterococcus faecium carriage in patients who have traveled in foreign countries: A single center 5-year prospective study

Published:February 11, 2022DOI:https://doi.org/10.1016/j.ajic.2022.01.031

      Highlights

      • Patients who travelled abroad without hospitalization.
      • Prevention measures for cross-transmission.
      • Survey of patients at high risk of CPE/VRE carriage.

      Background

      Numerous patients carrying carbapenemase-producing Enterobacterales (CPE) and/or vancomycin-resistant Enterococcus faecium (VRE) in France have previously travelled abroad. The risk of spreading CPE/VRE by patients who have stayed abroad without hospitalization is underexplored. This prompted us to screen and isolate all patients who travelled abroad in the previous 12 months upon admission to our hospital. Our aim was to evaluate the efficiency of this CPE/VRE-related risk policy.

      Methods

      From 2014 to 2018, patients who had travelled abroad in the previous year before their admission underwent microbiological screening and were pre-emptively isolated. Contact precautions were verified and CPE/VRE cross-transmission events investigated.

      Results

      Among 1,780 screened patients, 59 (3.3%) were colonized with CPE and/or VRE, of whom 17 (29.3%) were not hospitalized abroad. Nine generated 18 readmissions. No episodes of CPE/VRE cross-transmission were related to patients with a stay abroad without hospitalization, whereas 2 patients hospitalized abroad generated one episode each, despite implementation of contact precautions reaching values from 73.6% to 87.5%.

      Discussion

      Throughout 17 admissions and 18 readmissions, patients who stayed abroad without hospitalization represented a true risk of spreading CPE/VRE, without generating cross-transmission.

      Conclusions

      Our strategy of CPE/VRE-related risk policy is successful.
