Objective: To identify the microbiological profile of patients undergone active surveillance culture. Material and Methods: Prevalence study was performed at University Hospital in the Southeastern Region of Minas Gerais from March to December 2018, with eligible patients according to criteria established by the Hospital Infection Control Service of this unit, submitted to culture of surveillance by rectal and nasal swabs. The criteria were defined as: patients transferred from another institution with permanence higher than 96 hours; patients transferred from another institution at least 48 hours of hospitalization and submitted to some invasive device; replacement renal therapy; staying intensive care unit at least 72 hours by last 90 days; previously admitted by last 90 days at least of 30 days of hospitalization. The database was structured and analyzed through Excel and statistical analyzes by Med Calc. Results: 591 patients were identified and presented criteria for performing the surveillance culture, being 25.4% as positive. Most of frequent criteria for performing culture were: patients transferred from another institution with permanence higher than 96 hours and staying intensive care unit at least 72 hours by last 90 days. The microorganisms were mainly identified: methicillin resistant Staphylococcus aureus, Klebsiella pneumoniae and Acinetobacter baumannii resistant to carbapenems with 38.3%, 31.2% and 25.3%, respectively. Conclusion: The culture of active surveillance contributed to the early detection of resistant microorganisms, allowing early prevention, favoring the reduction of cross-dissemination. The database with results of surveillance cultures is an important strategy, because if rehospitalizations of these patients occur, infection control and care teams will be able to identify patients have already infected or colonized and make control behaviors on their admission.
