Initial Treatment Approach for Cough in Urgent Care Setting

For a patient presenting with just a cough in an urgent care setting, the first step is to determine if the cough represents a serious illness or a self-limited condition, then treat empirically based on the most likely cause while avoiding unnecessary antibiotics. 1

Initial Assessment

Begin by determining if the cough is:

• Acute (<3 weeks)
• Subacute (3-8 weeks)
• Chronic (>8 weeks)

Key History Points to Assess:

• Duration of cough
• Associated symptoms (fever, dyspnea, chest pain)
• Medication use (especially ACE inhibitors)
• Smoking status
• Exposure to irritants
• Comorbid conditions

Red Flags Requiring Immediate Attention:

• Signs of pneumonia or pulmonary embolism
• Hemoptysis
• Significant dyspnea
• Immunocompromised status

Treatment Algorithm

1. Acute Cough (<3 weeks)

Most acute coughs in urgent care are due to viral respiratory infections and are self-limited 1, 2.

For common cold with cough:

• First-generation antihistamine plus decongestant (e.g., brompheniramine/pseudoephedrine)
• NSAIDs for symptom relief
• Adequate hydration
• Rest

Important: Despite high prescription rates in urgent care settings (94% in one study), antibiotics are rarely indicated for uncomplicated acute cough 3.

2. Subacute Cough (3-8 weeks)

Determine if it's post-infectious or non-infectious:

For post-infectious cough:

• If upper airway cough syndrome (UACS) suspected: First-generation antihistamine/decongestant
• If bronchial hyperresponsiveness suspected: Consider short-term inhaled bronchodilator

For non-infectious causes: Approach as chronic cough

3. Chronic Cough (>8 weeks)

Systematically address the most common causes:

1. Upper Airway Cough Syndrome (UACS):

   • First-generation antihistamine/decongestant
   • Reassess in 2-3 weeks

2. Asthma:

   • Trial of inhaled bronchodilator
   • Consider short course of inhaled corticosteroids

3. Gastroesophageal Reflux Disease (GERD):

   • Proton pump inhibitor
   • Lifestyle modifications

Specific Considerations for Urgent Care

1. Avoid overuse of antibiotics - Most coughs are viral and self-limited, with mean duration of 16.4 days 2

2. Judicious use of symptom-relieving medications:

   • Cough suppressants for significant cough interfering with sleep
   • Avoid systemic corticosteroids unless clear indication (used in 70% of cases in one study despite limited evidence) 3

3. Chest X-ray indications:

   • Dyspnea (3x more likely to receive CXR) 3
   • Abnormal lung examination
   • Suspected pneumonia
   • Prolonged symptoms

4. Patient education:

   • Expected duration (acute cough typically lasts 2-3 weeks)
   • Return precautions
   • Smoking cessation counseling if applicable

Common Pitfalls to Avoid

1. Overprescribing antibiotics for viral coughs - this contributes to antibiotic resistance without improving outcomes

2. Excessive use of systemic corticosteroids - reserve for specific indications like asthma exacerbations

3. Inadequate follow-up planning - ensure patients know when to return if symptoms worsen or don't improve

4. Missing ACE inhibitor-induced cough - always check medication list and consider switching medications if patient is on an ACE inhibitor

5. Overlooking serious underlying conditions - maintain vigilance for red flags requiring further workup

Remember that cough can significantly impact quality of life, and addressing patient concerns while avoiding unnecessary treatments is key to effective management in the urgent care setting.
