Background:
Healthcare-associated infections (HAIs) have a significant impact on patient care worldwide and have serious implications for the Brazilian healthcare system.
Objectives:
This study aimed to describe the trends in HAIs in adult intensive care units (ICUs) using data from a national point-prevalence survey.
Design And Setting:
A point-prevalence study was conducted in 2019 across adult intensive ICUs in large acute care hospitals in Brazil.
Methods:
A matched case-control study was performed to assess the risk factors associated with the development of infection.
Results:
A total of 386 patients from 15 hospitals were studied, of whom 102 (26.4%; 102/386) were infected, and 76.5% had at least one ICU-acquired infection. In clinical-surgical ICUs (CSU), the prevalence of infections acquired in the unit was 77.9%, whereas in Coronary ICUs (COU), it was 68.7%. There was a predominance of pneumonia (51.0%), mainly caused by Gram-negative non-fermenters, and bloodstream infections (34.4%), predominantly caused by coagulase-negative Staphylococcus (CoNS). In the risk factor analysis, cancer and general antimicrobial use were independently associated.
Conclusion:
This study found a high burden of HAIs in adult ICUs in Brazil, mainly associated with the high use of antibiotics for infections and a worse prognosis.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
Standard Precaution
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...
