Should This Patient Be Discharged With Antibiotics?

No, this patient with viral pneumonia, rhonchi, and no oxygen requirement should NOT routinely be discharged with antibiotics. 1

Primary Recommendation

Previously well adults with viral pneumonia (influenza-related) in the absence of bacterial superinfection do not routinely require antibiotics. 1 The presence of rhonchi rather than wheezing does not change this fundamental principle—rhonchi indicate airway secretions but do not automatically indicate bacterial infection. 1

Clinical Decision Algorithm

Step 1: Assess for Bacterial Superinfection

Look for these specific warning signs that would warrant antibiotics: 1, 2

  • Recrudescent fever (fever that returns after initial improvement) 1, 2
  • Increasing dyspnea or breathlessness 1, 2
  • Worsening symptoms after initial improvement 2, 3
  • Inability to maintain clinical stability 1

If none of these features are present, antibiotics are NOT indicated. 1

Step 2: Verify Discharge Safety Criteria

The patient should NOT be discharged if ≥2 of the following are present: 1, 4

  • Temperature >37.8°C 1, 4
  • Heart rate >100/min 1, 4
  • Respiratory rate >24/min 1, 4
  • Systolic blood pressure <90 mmHg 1, 4
  • Oxygen saturation <90% 1, 4

Since this patient requires no oxygen and presumably meets stability criteria, discharge is appropriate WITHOUT antibiotics. 1

When Antibiotics ARE Indicated

Antibiotics should only be prescribed if: 1, 2

  1. High-risk patient with lower respiratory tract symptoms: Chronic lung disease (especially COPD), age >65, immunocompromised, chronic heart disease, diabetes 1, 2
  2. Evidence of bacterial pneumonia on chest X-ray with clinical deterioration 3, 4
  3. Worsening clinical course suggesting bacterial superinfection 1, 2

If Antibiotics Are Needed (Which They're NOT in This Case)

First-line oral therapy would be: 1, 3

  • Co-amoxiclav 625 mg three times daily 1, 3
  • OR Doxycycline 200 mg loading dose, then 100 mg once daily 1

Critical Pitfalls to Avoid

Do not prescribe antibiotics "just in case" for viral pneumonia. 1 This practice:

  • Contributes to antimicrobial resistance 5
  • Provides no clinical benefit in viral-only disease 5, 6
  • Exposes patients to unnecessary adverse effects 2

The presence of rhonchi does NOT indicate bacterial infection—it simply reflects airway secretions common in viral respiratory infections. 1

Discharge Instructions

Instead of antibiotics, provide: 1, 2

  • Antiviral therapy (oseltamivir 75 mg twice daily for 5 days) if within 48 hours of symptom onset OR if severely ill 2, 4
  • Return precautions: Come back if fever returns, breathing worsens, or symptoms don't improve within 5-7 days 1, 2
  • Supportive care: Adequate hydration, antipyretics (acetaminophen or ibuprofen), rest 4
  • Follow-up with primary care physician in 3-5 days 1

Bottom line: Discharge WITHOUT antibiotics unless specific evidence of bacterial superinfection develops. 1
