Association Between Carbapenem-Resistant Enterobacterales (CRE) Colonization Status at Time of Hospital Admission and the Subsequent Development of CRE Infection and Mortality in High-Risk Patients.

Purpose: The study aimed to determine the impact of Carbapenem-resistant Enterobacterales (CRE) colonization status on development of CRE infection and 30-day mortality outcomes in high-risk patients.

Patients And Methods: This retrospective cohort study was conducted at King Faisal Specialist Hospital and Research Center in Jeddah, Saudi Arabia from October 2022 to July 2023.
