BackgroundHospital acquired infections (HAI) and liberal use of broad-spectrum antibiotics are common in intensive care unit(ICU)s of low-middle income countries. We investigated the long-term association of a stepwise multifaceted educational program with the incidence of HAIs and antibiotics use in a Brazilian ICU. We also evaluated the program's cost impact.MethodsWe retrieved data from a prospective daily collected database of a twelve bedrooms ICU, all admitted patients within a period of eleven years were enrolled.FindingsFrom 03/15/2007 to 09/11/2019, we admitted 3059 patients where 2406 (79%) survived the ICU stay. Median age was 51 years-old, and median SAPS3 was 53. The initial density of catheter related blood infection (4.3 events / 1000 patients-day), urinary tract infection (9.2 event / 1000 patients-day) and ventilator associated pneumonia (54.9 events / 1000 patients-day) felt during the observed period to (0.35 events / 1000 patients-day), (0 events / 1000 patients-day), and (1.5 events / 1000 patients-day) respectively. The days of antibiotic therapy also decreased from 797.9 days of therapy / 1000 patients day to 292.3 days of therapy / 1000 patients day. The total cost per patient also decreased. The adjusted mortality rate was steady during the studied period from 23.2% to 22.9%.InterpretationA stepwise multifaceted educational program is an effective way to reduce hospital-associated infections, improve the rational use of antibiotics, and reduce costs. This impact occurred in a long term, and is probably consistent.Copyright © 2024 Elsevier Inc. All rights reserved.
