RESUMEN
OBJECTIVE: To determine the adherence and safety outcomes of a 5-day antibiotic course with a "time-out" for treatment of "blood culture-negative" pneumonia in the NICU. STUDY DESIGN: Prospective surveillance of all infants diagnosed with pneumonia at 7 NICUs from 8/2020-12/2021. Safety outcomes were defined a priori by re-initiation of antibiotic therapy within 14 days after discontinuation and overall and sepsis-related mortality. RESULTS: 128 infants were diagnosed with 136 episodes of pneumonia; 88% (n = 119) were treated with 5 days of definitive antibiotic therapy. Antibiotics were restarted within 14 days in 22 (16%) of the 136 pneumonia episodes. However, only 3 (3%) of the 119 episodes of pneumonia treated for 5 days had antibiotics restarted for pneumonia. Mortality was 5% (7/128); 5 of the 7 deaths were assessed as sepsis-related. CONCLUSION: Adherence to the 5-day definitive antibiotic treatment for "culture-negative" pneumonia was high and the intervention seemed safe.
