About this study

Official title: Impact of Fourier Transform Infrared Spectroscopy (FTIRS) on the Diffusion of ESBL Producing Enterobacterales in Intensive Care Units (ICU)

This study will assess the impact of FTIRS typing on the spread of ESBL-E in intensive care units

Read the detailed description

Multidrug resistant enterobacterales (MDR-E) are a major threat for patients hospitalized in intensive care units (ICUs). To prevent MDR-E spread in ICUs, rectal swabs are routinely performed and cultured on selective media. However, bacterial identification and antimicrobial susceptibility results are not sufficient to diagnose cross transmissions. The gold standard technique is based on genomic analysis that require whole genome sequencing (WGS) of bacteria and followed by multilocus sequence typing (MLST) and Single Nucleotide Polymorphism (SNP) typing. This technology is rather expensive and not applicable in all centers.

Fourier Transform InfraRed Spectroscopy (FTIRS) is a developing method for rapid bacterial typing. This technology is simple and results can be obtained in one hour. It is therefore adapted to continuous surveillance of MDR-E. In France, extended spectrum betalactamase producing enterobacteriaceae (ESBL-E) represent the vast majority of MDR-E. We postulate that early diagnosis of cross-transmission by FTIRS may prevent the spread of ESBL-E in ICUs and favor compliance with hygiene measures. The aim of this study will be to assess the impact of systematic FTIRS typing of ESBL-E on ESBL-E cross-transmissions in ICUs.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FTIR resultsDiagnostic test

    Weekly transmission of FTIRS typing of ESBL-E to centers

Study groups in NCT05872152
Study groupRoleWhat they receive
Standard careNo interventionStandard care are defined by routine procedures implemented in each center to prevent and control the diffusion of MDR-E bacteria in ICUs. In the first period of the study, the frequency of cross transmission will be assessed by sequencing the first ESBL-E isolate in each carrier patients (first isolate of a given species)
Transmission of FTIR resultsExperimentalIn second phase of the study, the result of FTIR typing of recovered ESBL-E isolates will be weekly transmitted to participating centers.

  2. Post intervention frequency of ESBL-E cross transmission as assessed by WGS

    Number of patients with hospital acquired ESBL-E / total number of ESBL-E carriers

    Measured: Month 24

Secondary outcomes (4)
  1. Sensitivity of FTIRS to diagnose cross transmissions compared to WGS

    Sensitivity

    Measured: Month 24

  2. Specificity of FTIRS to diagnose cross transmissions compared to WGS
