Antibiotic Use in Paediatric Patients Hospitalized with Acute Severe Asthma

Abstract

Abstract Background Antibiotic use during asthma exacerbations in paediatric patients is not routinely recommended but common practise in out-patient and in-patient settings. Objective of this study was to analyse frequency of antibiotic use during acute severe asthma exacerbations, antibiotic classes utilized and clinical decision-making. Methods All in-patient admissions over 10 years in a single German Children’s University hospital due to acute severe asthma were included in this retrospective analysis. Age, length of stay, oxygen supplementation, treatment, laboratory parameters and chest x-rays of all patients ranging from 1 to 17 years were analysed. Results 580 hospital admissions were included in this study. Overall antibiotic use was high but decreased with age (1–5 years 69,6%, 6–11 years 57,6% and 12–17 years 39,7%, p<0.001). Analysis of antibiotic treatment without clear indication showed a consistently lower treatment rate of 28.3%, with macrolides being the most common antibiotic class. Younger age significantly decreased, whereas, increase of CrP value, use of oxygen supplementation and concomitant fever all significantly increased the odds ratio (OR 0.967; 4.366, 2.472 and 2.011 respectively) of receiving antibiotic treatment without clear indication. Conclusion Antibiotic treatment without clear indication during acute severe asthma is common in this German single-centre cohort. Clinical parameters of more severe disease affect clinician’s decision to administer antibiotics despite evidence of bacterial infection or improved outcome.
