Appropriate sites for active surveillance of carbapenemase-producing Enterobacterales.

Carbapenemase-producing Enterobacterales (CPE) are considered a significant public health threat due to their high risk of transmission [1]. Surveillance cultures are performed for early detection of CPE colonization and to prevent additional transmission to other patients [2]. The World Health Organization and Centers for Disease Control and Prevention guidelines recommend stool and rectal swabs [1,3]. However, there are limited data on whether surveillance testing at various anatomical sites, in addition to stool sampling, could improve the sensitivity of CPE detection and thus assist with the prevention and control of CPE [2,4]. As such, we evaluated this possibility. This study was a retrospective analysis of CPE-positive patients treated between January 2016 and January 2021 at
