Résumé
The influence of the neonatal intensive care unit (NICU) design on the acquisition of multidrug-resistant organisms (MDROs) has not been well-documented. To examine the effect of single room unit (SRU) versus open bay unit (OBU) design on the incidence of colonization with MDROs and third-generation cephalosporin-resistant bacteria (3G-CRB) in infants admitted to the NICU. Retrospective cohort study, including all infants admitted to the NICU of a tertiary care academic hospital two years prior to and two years following the transition from OBU to SRU in May 2017. Weekly cultures of throat and rectum were collected to screen for MDRO carriership. Incidence of colonization (percentage of all infants and incidence density per 1000 patient-days) with MDROs and 3G-CRB were compared between OBU and SRU periods. Incidence analysis of 1293 NICU infants, identified 3.2% MDRO carriers (2.5% OBU, 4.0% SRU, not significant), including 2.3% extended-spectrum β-lactamase-producing Enterobacterales carriers, and 18.6% 3G-CRB carriers (17% OBU, 20% SRU, not significant). No differences were found in MDRO incidence density per 1000 patient-days between infants admitted to OBU (1.56) compared to SRU infants (2.63). Transition in NICU design from open bay to SRUs was not associated with a reduction in colonization rates with MDROs or 3G-CRB in our hospital. Further research on preventing the acquisition and spread of resistant bacteria at high-risk departments such as the NICU, as well as optimal ward design, are needed.

OBJECTIVE
To examine the effect of single room unit (SRU) versus open bay unit (OBU) design on the incidence of colonization with MDROs and third-generation cephalosporin-resistant bacteria (3G-CRB) in infants admitted to the NICU.
METHODS
METHODS
Retrospective cohort study, including all infants admitted to the NICU of a tertiary care academic hospital two years prior to and two years following the transition from OBU to SRU in May 2017. Weekly cultures of throat and rectum were collected to screen for MDRO carriership. Incidence of colonization (percentage of all infants and incidence density per 1000 patient-days) with MDROs and 3G-CRB were compared between OBU and SRU periods.
FINDINGS
RESULTS
Incidence analysis of 1293 NICU infants, identified 3.2% MDRO carriers (2.5% OBU, 4.0% SRU, not significant), including 2.3% extended-spectrum β-lactamase-producing Enterobacterales carriers, and 18.6% 3G-CRB carriers (17% OBU, 20% SRU, not significant). No differences were found in MDRO incidence density per 1000 patient-days between infants admitted to OBU (1.56) compared to SRU infants (2.63).
CONCLUSION
CONCLUSIONS
Transition in NICU design from open bay to SRUs was not associated with a reduction in colonization rates with MDROs or 3G-CRB in our hospital. Further research on preventing the acquisition and spread of resistant bacteria at high-risk departments such as the NICU, as well as optimal ward design, are needed.
