Outpatient Discharge Management after Acute Asthma Exacerbation

Systemic Corticosteroid Therapy

Prescribe oral prednisone 40–60 mg once daily for 5–10 days without tapering for adults with moderate‑to‑severe exacerbations; this regimen reduces relapse rates by roughly two‑thirds, with a number‑needed‑to‑treat of 13 to prevent one relapse requiring additional care. 1
Continue the oral prednisone course until peak expiratory flow (PEF) reaches ≥ 70 % of predicted or the patient’s personal best. 2
No taper is required for courses shorter than 7–10 days, particularly when the patient is already using inhaled corticosteroids. 1

Give prednisone or prednisolone 1–2 mg/kg/day in two divided doses (maximum 60 mg/day) for 3–10 days. 2
Calculate the dose using ideal body weight in overweight children to avoid excess exposure. 1

Consider a single intramuscular depot corticosteroid injection (e.g., methylprednisolone) as it may be as effective as oral therapy in preventing relapse. 2

Initiate or increase inhaled corticosteroid (ICS) therapy at discharge for all patients, because an emergency‑department visit usually reflects inadequate long‑term control. 1
Patients already on an ICS should continue that medication while receiving systemic corticosteroids. 2
For patients not previously prescribed an ICS, a conditional recommendation is to start one at discharge. 1

Provide a written asthma action plan that lists medication names, doses, and duration of therapy. 2
Include clear instructions for symptom and peak‑flow monitoring. 1
Specify objective thresholds (e.g., PEF values) that trigger step‑up therapy. 1
State when the patient should contact their physician and when they should seek emergency care. 1

Schedule an outpatient follow‑up appointment before discharge; doing so markedly improves the likelihood that patients receive appropriate ongoing care. 2
Failure to arrange follow‑up prior to discharge is identified as a critical error linked to subsequent emergency visits. 1

The patient may be discharged when PEF or FEV₁ is ≥ 70 % of predicted or of the patient’s personal best. 2
Symptoms should be minimal or absent. 1
The patient must remain stable for 30–60 minutes after the last bronchodilator dose. 2

Omitting a written action plan, adequate systemic corticosteroid duration, or verification of inhaler technique increases relapse risk.
Not initiating or escalating inhaled corticosteroid therapy at discharge overlooks a common cause of emergency‑department presentations. 1

The American Academy of Allergy, Asthma, and Immunology recommends that patients with asthma should be discharged with inhaled short-acting beta-agonists (SABAs), systemic corticosteroids, and inhaled corticosteroids (ICS) to prevent relapse and improve outcomes 3, 4
All patients should continue treatment with inhaled SABAs (such as albuterol) for as-needed symptom relief, with dosing adjusted based on symptom severity, typically 2-4 puffs every 4-6 hours as needed 3
Patients should be prescribed oral corticosteroids (prednisolone 30-60 mg daily) to continue for 3-10 days after discharge, with a typical regimen of 40-60 mg in single or divided doses for adults 4, 5
For children, oral corticosteroids should be prescribed at 1-2 mg/kg/day (maximum 60 mg/day) for 3-10 days 5
The American Academy of Allergy, Asthma, and Immunology recommends that patients at high risk of non-adherence consider intramuscular depot corticosteroid injections 4

For mild-to-moderate asthma, patients should use SABA (albuterol MDI, 4-8 puffs every 1-4 hours as needed), oral corticosteroid (prednisolone 40-60 mg daily for 5-10 days), and ICS (low-dose) 3, 5
For severe asthma, patients should use SABA (albuterol MDI, 4-8 puffs every 1-4 hours as needed), oral corticosteroid (prednisolone 40-80 mg daily for 5-10 days), and consider moderate-dose ICS or ICS/LABA combination 3, 5

Patients should have been on discharge medications for at least 24 hours before leaving the hospital, and nebulizers should be replaced by standard inhaler devices 24-48 hours before discharge unless the patient requires a nebulizer at home 6
Ensure PEF is >75% of predicted or personal best with diurnal variability <25% before discharge, and provide written instructions on medication use, including dosing schedule and duration 3, 4, 6
Provide a written asthma action plan that includes when to increase treatment, when to call their doctor, and when to return to the hospital, and schedule follow-up with primary care provider within 1 week of discharge and with respiratory specialist within 4 weeks 4, 6
Inadequate duration or dosing of systemic corticosteroids increases risk of relapse, and not checking inhaler technique before discharge can result in medication delivery issues 4, 6
Overlooking the need for a written action plan significantly increases risk of relapse 6
