Modification of empirical antimicrobial regimen during the first 72 hours of hospitalisation
Abstract
OBJECTIVE: The aims of this study were to determine the empirical antibiotic therapy used in patients admitted to the Emergency Department who were later hospitalised, and to describe the antibiotic changes during their first days of hospitalisation.
METHOD: All 14-year-old patients admitted to the Emergency Department who were started on antibiotic therapy and subsequently were hospitalised for at least 72 hours in an in-patient hospital ward, were included in a prospective observational study. Patients underwent daily follow-up during the first three days of hospitalisation. The type of infection, microbiological data and empirical antibiotic therapy and its changes were registered.
RESULTS: 225 patients were included in this study. The most frequent types of infection diagnosed were infection of the respiratory airways, pneumonia and skin and soft-tissue infection. Amoxicillin-clavulanic acid was the most widely prescribed antibiotic followed by levofloxacin and third generation cephalosporins. Microbiological samples were taken in 80 (36%) patients. Of the 225 antimicrobial regimens started in the Emergency Department, 94 (42%) were changed during the first 72 hours of hospitalisation: 37 (16%) were completely modified, 31 (14%) were discontinued and antibiotics were added or stopped from the existing regimen in 26 cases (12%). Among these 94 patients whose treatment was changed, only in 40 (42%) there was a microbiological result for aiding in the adjustment of the…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 225 participants or records.
