Initial Management of Pediatric Asthma in Primary Care

Diagnostic Confirmation

The American Thoracic Society recommends confirming the diagnosis of asthma by identifying key clinical features, including family history of asthma or atopy, repeated wheeze or recurrent cough, symptom triggers, and age considerations, in children with persistent asthma symptoms 1, 3
The diagnosis of asthma should be based on the presence of repeated wheeze or recurrent cough, especially nocturnal, and symptom triggers, including viral infections, exercise, emotional disturbances, allergens, and cigarette smoke 1
The American Academy of Pediatrics recommends considering age when diagnosing asthma, as 50% of children with asthma develop symptoms by age 3, and 80% by age 5 1

The American Academy of Pediatrics recommends initiating low-dose inhaled corticosteroids (ICS) as first-line controller therapy for children with persistent asthma symptoms, regardless of age 1, 2
For children under 5 years, the American Academy of Pediatrics recommends initiating low-dose ICS via nebulizer, dry powder inhaler (DPI), or metered-dose inhaler (MDI) with holding chamber/face mask as first-line therapy 2
For children 5-11 years, the American Academy of Pediatrics recommends initiating low-dose ICS as first-line controller therapy, with alternative options including montelukast, cromolyn/nedocromil, or sustained-release theophylline 2

The American Thoracic Society recommends addressing maternal smoking as the most important modifiable environmental trigger, and general practitioners are ideally positioned to observe and modify this 1, 4
The American Academy of Allergy, Asthma, and Immunology recommends using specific IgE measurements and skin prick tests to identify allergies, and avoiding ineffective interventions such as acaricides 1

The American Thoracic Society recommends targeting the following outcomes to reduce morbidity and improve quality of life: minimal chronic symptoms, minimal exacerbations, minimal need for rescue bronchodilators, no activity limitations, and minimal adverse effects from medications 1, 3
The American Academy of Pediatrics recommends monitoring peak expiratory flow (PEF) measurements to adjust medications, with a goal of PEF ≥80% of predicted or best, and circadian variation <20% 1

The American Academy of Pediatrics recommends providing both oral and written instructions covering proper inhaler technique, when and how to adjust medications, written action plan, and when to call for help 1, 3
The American Thoracic Society recommends teaching children ≥5 years and families how to use peak expiratory flow (PEF) measurements to adjust medications 1

The American Academy of Pediatrics recommends assessing response to therapy within 4-6 weeks, and considering alternative therapies or diagnoses if no clear benefit is observed 2
The American Thoracic Society recommends tracking parameters such as days missed from school, daytime and nighttime cough frequency, rescue medication use, activity limitation, and wheeze at each visit 1

The American Thoracic Society recommends providing high-flow oxygen (40-60%) via face mask, target SpO₂ >92%, and nebulized beta-agonist (salbutamol 5 mg or terbutaline 10 mg) for acute severe asthma 5, 6
The American Academy of Pediatrics recommends adding systemic corticosteroids (prednisolone 1-2 mg/kg body weight) for 1-5 days, and ipratropium 100 mcg nebulized every 6 hours if life-threatening features are present 1, 5, 6
