Outpatient Discharge Management for Acute Asthma Exacerbation
All patients discharged from the emergency department after an acute asthma exacerbation should receive a 5-10 day course of oral corticosteroids (prednisone 40-60 mg daily for adults), initiation or continuation of inhaled corticosteroids, a written asthma action plan, verified inhaler technique, and a scheduled follow-up appointment within one week. 1
Systemic Corticosteroids at Discharge
Prescribe oral prednisone 40-60 mg daily for 5-10 days without tapering for adults with moderate-to-severe exacerbations. 1 This reduces relapse rates by approximately two-thirds, with as few as 13 patients needing treatment to prevent one relapse requiring additional care. 2
Adult Dosing
- Prednisone 40-60 mg once daily (or divided into two doses) for 5-10 days 1
- Continue until peak expiratory flow reaches ≥70% of predicted or personal best 1
- No tapering required for courses <7-10 days, especially if patient is on inhaled corticosteroids 1
Pediatric Dosing
- Prednisone or prednisolone 1-2 mg/kg/day in two divided doses (maximum 60 mg/day) for 3-10 days 1
- Calculate dose using ideal body weight in overweight children to avoid excessive exposure 1
Alternative for Non-Adherent Patients
- Consider intramuscular depot corticosteroid injection (e.g., methylprednisolone) for patients at high risk of non-adherence, as this may be as effective as oral therapy in preventing relapse 1, 3, 2
Inhaled Corticosteroids at Discharge
Initiate or increase inhaled corticosteroids at discharge in all patients, as ED visits typically result from inadequate long-term asthma control. 1
- Patients already on inhaled corticosteroids should continue them while taking systemic corticosteroids 1
- Consider initiating inhaled corticosteroids in patients not already receiving them (conditional recommendation) 1
- Start at higher doses than pre-admission levels 4
- Ensure patient has been stable on discharge medications for at least 24 hours before leaving 3
Bronchodilator Therapy
- Prescribe short-acting beta-agonist (albuterol) metered-dose inhaler for as-needed symptom relief 3
- Typical dosing: 2-4 puffs every 4-6 hours as needed, adjusting based on symptom severity 3
- For severe exacerbations: 4-8 puffs every 1-4 hours as needed initially 3
Patient Education and Inhaler Technique
Verify correct inhaler technique before discharge—this is a core component of preventing relapse. 4
- Demonstrate all steps of metered-dose inhaler use with spacer device 4
- Have patient demonstrate technique back to you 4
- Failing to verify inhaler technique is a common pitfall that results in medication delivery failure 4, 3
Written Asthma Action Plan
Provide a written discharge plan—verbal instructions alone are insufficient. 1, 4
The plan must include:
- Medication names, doses, and duration 1
- Instructions for monitoring symptoms and peak flow 1
- Specific thresholds for when to increase treatment 1, 4
- When to call their physician 1, 4
- When to return to the emergency department 1, 4
- Peak flow meter prescription with instructions on target values 3
Follow-Up Arrangements
Schedule outpatient follow-up before discharge—this dramatically increases the likelihood that patients will obtain appropriate ongoing care. 1, 4
- Primary care follow-up within 1 week of discharge 4, 3
- Respiratory specialist follow-up within 4 weeks 4, 3
- Failing to schedule follow-up before discharge is a critical error, as ED visits often result from inadequate long-term management 1
Discharge Criteria
Patients can be discharged if: 1
- FEV₁ or peak expiratory flow ≥70% of predicted or personal best
- Symptoms are minimal or absent
- Stable for 30-60 minutes after most recent bronchodilator dose
- Peak flow >75% of predicted with diurnal variability <25% 3
Critical Pitfalls to Avoid
- Discharging without a written action plan—verbal instructions are not enough 4
- Not prescribing adequate corticosteroid duration (<3 days is insufficient to prevent relapse) 4
- Failing to schedule follow-up before discharge—dramatically reduces adherence to ongoing care 4
- Not verifying inhaler technique—leads to medication delivery failure 4, 3
- Inadequate systemic corticosteroid dosing or duration—increases relapse risk 3
- Overlooking the need to initiate or increase inhaled corticosteroids—ED visits signal inadequate chronic control 1
