Short‐ and long‐term respiratory outcomes in neonates with ventilator‐associated pneumonia
Archive ouverte
International audience. Abstract Background and Objective Ventilator‐associated pneumonia (VAP) is a common nosocomial infection in critical care settings and might have important long‐term consequences in neonates. Our aim is to clarify the short‐ and long‐term respiratory outcomes of neonates affected by VAP. Methods Prospective, population‐based, cohort study with 12 months follow‐up based on clinical examinations and diary‐based respiratory morbidity score, conducted in an academic tertiary referral neonatal unit with dedicated follow‐up program. Results A total of 199 inborn neonates consecutively ventilated for at least 48 hours were eligible for the study. One hundred fifty‐one were finally enrolled and classified as “exposed” or “unexposed” to VAP, if they fulfilled (or not) VAP criteria once during their stay. Bronchopulmonary dysplasia (BPD) incidence was significantly higher in exposed (75%) than in unexposed babies (26.8%; relative risk [RR]: 2.8 [1.9‐4.0]; Adj RR : 3.5 [1.002‐12.7]; P = .049; number needed to harm = 2.07), although the composite BPD/mortality did not differ. Exposed patients showed longer intensive care unit stay (87 [43‐116] vs 14 [8‐52] days; St. β = 0.24; P < .0001) and duration of ventilation (15 [10‐25] vs 5 [4‐8] days; St. β = 0.29; P < .0001) than unexposed neonates. Exposed patients also showed less ventilator‐free days (11 [5‐17.7] vs 22 [14‐24] days; St. β = −0.15; P = .05) compared to unexposed. Respiratory infections, use of drugs, rehospitalization for respiratory reasons, home oxygen therapy, their composite outcome, and diary‐based clinical respiratory morbidity score were similar between the cohorts. Conclusion Neonatal VAP seems associated to higher incidence of BPD, longer ventilation, and intensive care stay but it does not affect long‐term respiratory morbidity.
