Retrospective review of 200 children hospitalised with acute asthma. Identification of intervention points: A single centre study

Aim Indigenous Australians with asthma have higher morbidity and mortality compared with non‐Indigenous Australians. In children hospitalised with acute asthma, we aimed to (i) determine if acute severity, risk factors and management differed between Indigenous and non‐Indigenous children; and (ii) identify intervention points to reduce morbidity and mortality of asthma. Methods Retrospective review of 200 children hospitalised to Royal Darwin Hospital with asthma. We compared admission characteristics, severity indices, treatment, discharge plans and readmissions in Indigenous and non‐Indigenous children. Results Median age was 3.6 years (interquartile range 2.2, 6.8). A significantly higher proportion of Indigenous children (95.2%) were exposed to tobacco smoke compared with non‐Indigenous children (45.7%). The difference in proportions was −0.41 (95% confidence interval (CI) −0.60, −0.22). Other risk factors, asthma severity (moderate 83.9% vs. 83.3%; severe 16% vs. 16.1%), length of stay (1.9 vs. 1.3 days) and readmission rate (27.4% vs. 27.5%) were similar between Indigenous and non‐Indigenous children. Indigenous children were significantly more likely to be followed up in a community clinic (difference in proportions = 0.10, 95% CI 0.1, 0.17) and less likely by a paediatrician. Only 62.5% of all children had an asthma action plan on discharge. Conclusion Unlike other common respiratory diseases requiring hospitalisation, biological factors are unlikely major contributors to the known gap in asthma outcomes between Indigenous and non‐Indigenous children. Intervention points include better identification, documentation and management of tobacco smoke exposure, delivery of salbutamol and discharge planning (including education and utilisation of asthma action plans).
