What is the appropriate discharge plan for a 4‑year‑old boy presenting to the emergency department with a 5‑day history of cough and congestion, a normal chest radiograph, normal vital signs, brief wheezing that resolves after coughing, and no improvement after nebulized albuterol?

Supportive Care

This 4-year-old with a 5-day cough, normal chest radiograph, normal vital signs, transient wheezing that resolves with coughing, and no response to albuterol should be discharged with supportive care only. 1

Clinical Reasoning

This child presents with non-specific cough (dry cough without specific cough pointers) in the context of a likely post-viral illness. 1 The key features that guide this recommendation include:

• Normal vital signs rule out severe asthma or pneumonia requiring immediate intervention 1
• Normal chest radiograph obtained yesterday excludes pneumonia and other serious pulmonary pathology 1
• Scant wheezing that resolves after coughing suggests airway irritation rather than true bronchospasm 1
• No improvement after nebulized albuterol indicates this is not asthma or reversible bronchospasm 1
• 5-day duration is consistent with expected course of post-viral cough, which typically improves by one week in 75% of children but may persist up to 2 weeks in 50% 2

Why Not Albuterol Inhaler?

The lack of response to nebulized albuterol in the ED is a critical finding. 1 When bronchodilators fail to produce clinical improvement, continuing them at home is not indicated. 1 This child does not meet criteria for asthma or asthma-like illness, which would require:

• Reversible airflow obstruction demonstrated by response to bronchodilator 1, 3
• Persistent wheezing (not transient wheezing that resolves with coughing) 1
• Clinical improvement with trial of asthma medication 3

Why Not Antibiotics?

Neither amoxicillin nor azithromycin is indicated because:

• Normal chest radiograph rules out bacterial pneumonia 1, 4
• Normal vital signs (no tachypnea, no fever, normal oxygen saturation) indicate low risk of bacterial infection 4
• The clinical picture is consistent with post-viral cough, which is one of the two most common causes of chronic cough in children 5, 2
• At 5 days duration with improving course (scant wheezing only), this represents expected natural history of viral respiratory infection 2

Appropriate Discharge Plan

Watch, wait, and review is the recommended approach for non-specific cough in children. 1 Specifically:

• Reassurance that 50% of children may still be coughing at 2 weeks post-viral illness 2
• Return precautions: Advise parents to return if the child develops fever, increased work of breathing, inability to feed, or worsening symptoms 1
• Environmental modifications: Address tobacco smoke exposure and other irritants 3
• Follow-up in 2-4 weeks if cough persists to reassess for other etiologies 1

Common Pitfalls to Avoid

• Over-diagnosing asthma in children with chronic non-specific cough who have normal lung function and no response to bronchodilators 3
• Prescribing unnecessary antibiotics for viral illnesses, which contributes to antibiotic resistance without benefit 2
• Continuing ineffective bronchodilator therapy when there is no demonstrated response 1
• Underestimating the natural duration of post-viral cough, leading to premature intervention 2

When to Escalate Care

Re-evaluation is warranted if: 1

• Cough persists beyond 4 weeks (becomes truly chronic)
• Development of specific cough pointers (productive/wet cough, hemoptysis, failure to thrive, digital clubbing)
• Worsening symptoms or development of respiratory distress
• Recurrent episodes suggesting underlying asthma
