Which of the following is an admission criterion for COPD?

• A. Severe or worsening dyspnea not responding to ED treatment
• B. Rapid improvement with ED treatment
• C. Decreased work of breathing
• D. SpO2 consistently above 92% on room air

Answer: (A)

The main idea is recognizing when a COPD exacerbation requires hospital admission versus can be managed as an outpatient. Severe or worsening dyspnea that does not respond to initial ED treatment signals ongoing significant respiratory impairment and the need for close inpatient monitoring, often with escalation of therapy such as noninvasive ventilation or ICU care if needed. This reflects a higher risk of respiratory failure or deterioration, which admission aims to prevent.

In contrast, rapid improvement after ED treatment suggests the patient is stabilizing and can likely be discharged with appropriate follow-up and outpatient therapy. Decreased work of breathing indicates improvement rather than the need for admission. SpO2 consistently above 92% on room air shows adequate oxygenation and does not by itself mandate admission, provided the patient remains clinically stable.

So the admission criterion here is the severe or worsening dyspnea not responding to initial ED management.
