Abstract
OBJECTIVES: to analyze the rate of antimicrobial dose omission in intensive care units. METHODS: cross-sectional study carried out between March 1 and September 30, 2023, in intensive care units of a University Hospital in Rio de Janeiro. RESULTS: the sample consisted of 452 prescriptions and 1467 antimicrobial doses. The dose omission rate was 4.29%. Each antimicrobial prescribed increased the chance of omission by 51%. The strategy of double-checking prescriptions helped prevent 30% of antimicrobial dose omissions (p=0.0001). CONCLUSIONS: monitoring the omission of antimicrobial doses can guide nursing actions to improve quality and patient safety, contributing to the prevention of medication errors, antimicrobial stewardship and the fight against antimicrobial resistance.
