Components of enhanced care intervention; rationale for inclusion and member of staff performing each task

Factors contributing to suboptimal care	Component of intervention	Rationale	Staff*
	Assessment
Assessment may be rushed or not systematic: symptoms often under-reported or under-recognised	Administration of cACT	Objective and repeatable measurement of symptoms	L
	Measurement of FeNO	Identify airway inflammation phenotype in this population	L
	Spirometry measurement	Objective measurement of airway obstruction	L
	Spirometry QC/interpretation	Objective measurement of airway obstruction	N
	Physical examination (auscultate chest, look for clubbing/lymph nodes)	Exclude comorbidity or misdiagnosis (congenital/rheumatic heart disease, TB)	N
	Treatment optimisation
Clinicians reluctant to prescribe ICS and escalate dose if needed	Treatment increased according to protocol based on cACT and FEV₁/FVC ratio	Encourage appropriate use of ICS	L/N
	Asthma education
Fears and misconceptions, poor understanding of asthma and inhalers	1-hour individualised asthma education session	Increase knowledge levels, improve inhaler technique and compliance	L
	6-week review: revision of asthma education		L

*Staff responsible for performing each intervention task: L, lay educator (non-clinical); N, nurse.
cACT, Childhood Asthma Control Test; FeNO, exhaled nitric oxide; ICS, inhaled corticosteroid; QC, quality control.;
