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

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.

Epidemiology of Clostridioides difficile infections, France, 2010 to 2017

BackgroundClostridioides difficile is a leading cause of healthcare-associated diarrhoea in middle and high-income countries. Up to 2018, there has been no systematic, annual surveillance for C. difficile infections (CDI) in France.AimsTo provide an updated overview of the epidemiology of CDI in France between 2010 and 2017 based on five different data sources.MethodsThis is a descriptive study of retrospective surveillance and alerts data. Incidence of CDI cases was estimated through the CDI incidence survey (2016) and data from the French National Uniform Hospital Discharge Database (PMSI; 2010-16). Testing frequency for CDI was estimated through the CDI incidence survey and point prevalence studies on healthcare-associated infections (HAI; 2012 and 2017). The national early warning response system for HAI (HAI-EWRS, 2012-17) and National Reference Laboratory data (2012-17) were used to follow the number of severe CDI cases and/or outbreaks.ResultsIn 2016, CDI incidence in acute care was 3.6 cases per 10,000 patient days (PD). There was a statistically significant increase in CDI incidence between 2010 and 2016 (+ 14% annually) and testing frequency was 47.4 per 10,000 PD. The number of CDI HAI-EWRS notifications decreased between 2015 and 2017 with only a few large outbreaks reported.ConclusionThe CDI incidence estimate increased from 2010, but remained below the European average of 7 per 10,000 PD in 2014; there were fewer severe cases or clusters reported in France. The consistency between PMSI and laboratory-based estimated CDI incidence could allow for more routine monitoring of CDI incidence.
