Infection Risk Associated With Digestive MDRO Carriage in Hospitalized Patients

Repeated rectal swab collection for screening digestive colonization with multidrug-resistant organisms (MDRO), performed at admission (or within 14 days prior), on day 7, weekly during hospitalization, and at discharge.

Structured phone interview conducted 30 days post-discharge, using a standardized questionnaire assessing new infections, rehospitalizations, antibiotic use, and self-rated health status.
