Background: Infections caused by ESBL producing enterobacteriaceae (ESBL-E) and carbapenem resistant enterobacteriaceae (CRE) are associated with high morbidity, mortality rates and costs. Frequently these infections develop in previously colonized patients, who can also become a source of transmission and amplification of colonization both inside and outside hospital settings. Objectives: To determine the frequency of rectal colonization of CRE and ESBL-E among patients admitted to the emergency service of Cayetano Heredia Hospital, as well as to evaluate colonization related factors. Material and Methods: An analytical cross-sectional design study was performed from December 2019 to March 2020. Samples were collected via rectal swab or fecal swab, then cultured in chromogenic media (ChromAgar mSuperCarba and ESBL), positive growths were then confirmed via antibiogram according to the Clinical and Laboratory Standards Institute guidelines. Results: CRE and ESBL-E colonization frequency was 8.1% (n=12) and 73.7% (n=109), respectively. Hospitalization during the previous year (Adjusted Prevalence ratio 1.10; IC95% 1.02-1.18), chronic liver conditions (Adjusted PR 1.11; IC 95% 1.01-1.23), age >75 years (Adjusted PR 1.09; IC 95% 1.01-1.19) were significant associated factors to colonization by either CRE or ESBL-E. Conclusions: CRE and ESBL-E colonization frequency was found to be higher than previously reported in local and Latin American studies. Further studies are required to evaluate with more precision the associated factors to CRE or ESBL-E colonization in order to help in the design of specific infection control measures.
