In a 35-year-old Hispanic man with acute bronchitis who has received two courses of systemic prednisone without improvement, what is the best next step in management?

Stop the Prednisone—This Patient Needs Diagnostic Reassessment, Not More Steroids

In a 35-year-old man with presumed bronchitis failing two courses of prednisone, the best next step is to stop corticosteroids immediately and perform a focused diagnostic evaluation to exclude pneumonia, asthma, pertussis, or other conditions masquerading as "bronchitis." Systemic corticosteroids have no role in uncomplicated acute bronchitis and should not be prescribed for this condition. 1, 2

Why Prednisone Was Wrong in the First Place

• Acute bronchitis is 89–95% viral and does not respond to corticosteroids, which target inflammation rather than the underlying viral pathogen. 1
• The European Society of Clinical Microbiology and Infectious Diseases explicitly recommends against prescribing systemic corticosteroids for acute bronchitis, as they provide no consistent benefit and expose patients to unnecessary medication risks. 3, 1
• The American Academy of Family Physicians found that NSAIDs at anti-inflammatory doses and corticosteroids have not demonstrated efficacy in acute otitis media or bronchitis. 3
• Repeated corticosteroid courses without improvement strongly suggest either misdiagnosis or a condition requiring entirely different management. 1

Diagnostic Algorithm: What This Patient Actually Has

Step 1: Rule Out Pneumonia First

• Check vital signs immediately: heart rate >100 bpm, respiratory rate >24 breaths/min, or oral temperature >38°C all suggest pneumonia, not bronchitis. 1
• Perform a focused chest examination for focal findings (crackles, egophony, increased tactile fremitus). 1
• If any one of these findings is present, obtain a chest radiograph to exclude pneumonia before proceeding. 1

Step 2: Consider Undiagnosed Asthma or COPD

• Approximately one-third of patients diagnosed with "recurrent acute bronchitis" actually have undiagnosed asthma or COPD exacerbations. 1
• Perform spirometry or peak-flow testing in patients who smoke or have risk factors; ≥12% and ≥200 mL FEV₁ improvement after bronchodilator (or ≥20% peak-flow improvement) confirms reversible airway disease. 1
• Cough-variant asthma should be suspected in adults with persistent cough lasting >2–3 weeks that worsens at night or after cold/exercise exposure. 1

Step 3: Evaluate for Pertussis

• If the patient has paroxysmal cough, post-tussive vomiting, inspiratory "whoop," or cough >2 weeks, pertussis must be considered. 1
• When pertussis is confirmed or strongly suspected, prescribe a macrolide antibiotic (azithromycin or erythromycin) immediately and isolate the patient for 5 days from treatment start. 1

Step 4: Reassess for Other Diagnoses

• If cough persists >3 weeks, consider gastroesophageal reflux, upper-airway cough syndrome, or chronic bronchitis. 1
• If fever persists >3 days, this suggests bacterial superinfection or pneumonia rather than simple viral bronchitis. 1

What TO Do: Evidence-Based Management

For Uncomplicated Viral Bronchitis (Once Other Diagnoses Excluded)

• Patient education is the cornerstone: Inform the patient that cough typically lasts 10–14 days and may persist up to 3 weeks even without treatment. 1
• Symptomatic relief only:
  • Antitussives (codeine or dextromethorphan) for bothersome dry cough, especially at night. 1
  • Short-acting β₂-agonists (e.g., albuterol) only if wheezing accompanies the cough. 1
  • Environmental measures: Remove irritants (dust, allergens) and use humidified air. 1

For Asthma (If Diagnosed)

• Initiate inhaled corticosteroids (e.g., budesonide, fluticasone) as controller therapy. 1
• Provide a short-acting β₂-agonist (albuterol) for acute symptom relief. 1
• Refer for pulmonary function testing to confirm diagnosis and guide long-term management. 1

For Pertussis (If Suspected)

• Prescribe azithromycin 500 mg on day 1, then 250 mg daily for 4 days or erythromycin 500 mg four times daily for 14 days. 1
• Isolate the patient for 5 days from treatment start to prevent transmission. 1

Critical Pitfalls to Avoid

• Do not prescribe antibiotics for uncomplicated viral bronchitis, as they shorten cough by only ≈0.5 days (≈12 hours) while increasing adverse events (RR 1.20; 95% CI 1.05–1.36). 1
• Do not assume purulent (green/yellow) sputum indicates bacterial infection—this occurs in 89–95% of viral cases and reflects inflammatory cells, not bacteria. 1
• Do not prescribe corticosteroids for acute bronchitis, as they provide no benefit and expose patients to unnecessary medication risks. 3, 1
• Do not continue the same failed treatment—two courses of prednisone without improvement mandate diagnostic reassessment, not a third course. 1

Communication Strategy

• Explain that antibiotics and corticosteroids do not shorten viral bronchitis and may cause side effects (diarrhea, rash, yeast infection, hyperglycemia). 1
• Emphasize that physician-patient communication has a greater impact on patient satisfaction than prescribing medications. 1
• Refer to the illness as a "chest cold" rather than "bronchitis" to lower expectations for medications. 1
• Advise the patient to return if fever persists >3 days, cough persists >3 weeks, or symptoms worsen rather than gradually improve. 1
