Determinants of Cough and Caregivers’ Quality of Life in Paediatric Asthma Exacerbations
2020
OBJECTIVES In hospitalized and non-hospitalized children with asthma exacerbations, we evaluated the determinants of: (a) prolonged cough on day-14; and (b) asthma quality of life (QoL) questionnaires for parents (PACQLQ) on day-21. We hypothesized that children with more severe acute asthma are more likely to have prolonged cough and/or poorer PACQLQ during the recovery phase. DESIGN Prospective cohort study performed during 2009-2011. METHODOLOGY 244 children aged 2-16 years presenting with acute asthma to the Emergency Departments of 2 hospitals were recruited. Clinical history, examination, baseline asthma severity and acute asthma severity on presentation were documented. Validated daily cough diaries and weekly PACQLQ were recorded for 14 and 21-days respectively. RESULTS 34.4% and 32.2% of children who returned the day- and night-time cough diaries respectively had prolonged cough. Those on regular inhaled corticosteroids (ICS) were significantly more likely to have a daytime or night-time cough score of ≥1 on day-14 [Odds Ratio (ORadjusted )=4.70, 95%CI 1.65, 13.35, p=0.004 and ORadjusted =2.65, 95%CI 1.05, 6.69, p=0.040 respectively]. PACQLQ on day-21 was significantly poorer in younger children [mean difference (MD)=-0.04 per year, 95%CI -0.08, -0.01, p=0.016], those on ICS (MD=-0.31, 95%CI -0.52, -0.09, p=0.005), leukotriene antagonists (MD=-0.42, 95%CI -0.83, -0.02, p=0.040) and in those who had an unplanned visit for asthma on day-21 (MD=-1.20, 95%CI -1.61, -0.78, p=0.0001). CONCLUSIONS Post an acute asthma exacerbation, children on regular ICS were more likely to have prolonged cough and poorer QoL. While this may be reflective of asthma severity or control, its association deserves further evaluation. This article is protected by copyright. All rights reserved.
