Most COPD exacerbations don’t go wrong because we don’t know what to do.

They go wrong because of small, repeated decisions that quietly worsen outcomes.

If you’ve spent enough time on the wards, you’ve seen it: a patient who should improve stalls, deteriorates, or bounces back within weeks. Not because COPD is untreatable—but because of how we treat it.

Here are six common mistakes I still see in hospitalized COPD exacerbations.

1. Giving Too Much Oxygen

Oxygen is often treated as benign. It isn’t.

In patients with COPD, aggressive or non-titrated oxygen can worsen hypercapnia, precipitate respiratory acidosis, and increase the risk of intubation. The reflex to normalize oxygen saturation is understandable—but harmful.

For most COPD exacerbations, the goal is not “normal.”
The target is usually 88–92%.

When saturations climb higher than that, outcomes often get worse, not better.

2. Underusing Bronchodilators Early

Bronchodilators are the foundation of treatment—yet they’re often underutilized when they matter most.

Delayed initiation, wide spacing of treatments, or relying on PRN dosing in a visibly tight patient slows recovery. If airflow obstruction isn’t relieved early, everything else works less effectively.

Frequent short-acting bronchodilators early in the course, with prompt addition of anticholinergics, can significantly change the trajectory of the hospitalization.

This step is simple—and too often missed.

Please don’t hold the patient’s home LABA and LAMA inhalers during the exacerbation, as their benefits persist during acute exacerbations.

3. Prolonged or Excessive Steroid Therapy

More steroids do not equal better outcomes.

Despite strong evidence, patients are still commonly kept on high-dose IV steroids for extended periods. In reality, short courses work just as well.

For most patients, prednisone 40 mg daily for five days is sufficient. Oral therapy is preferred, and a taper isn’t needed for short courses.

Longer or higher-dose regimens only increase hyperglycemia, infection risk, delirium, and length of stay—without added benefit.

4. Reflexive Antibiotic Use

Not every COPD exacerbation is infectious.

Antibiotics are often started automatically, even in the absence of sputum purulence or other signs of bacterial infection. This doesn’t improve outcomes and contributes to resistance and medication-related harm.

Antibiotics are indicated in COPD exacerbations when patients have clinical signs of bacterial infection, particularly increased sputum purulence combined with other cardinal symptoms, prior positive sputum cultures, or require mechanical ventilation.
And when indicated, shorter courses—around five days—are usually enough.

Treat the patient, not the habit.

5. Delaying Noninvasive Ventilation

This is one of the most consequential mistakes.

Patients with acute hypercapnic respiratory failure are sometimes left on oxygen alone for too long. Rising CO₂ and falling pH should trigger early action—not watchful waiting.

Early noninvasive ventilation reduces intubation rates, shortens ICU stays, and improves survival. Delaying it often means losing the window where it could have prevented invasive ventilation altogether.

Oxygen alone is not enough when ventilation is failing.

6. Poor Discharge Planning

Many COPD admissions fail after discharge.

Patients leave the hospital without proper inhaler technique education, without a written action plan, and without timely follow-up. The result is predictable: poor adherence and high readmission rates.

A few minutes spent reviewing inhaler technique, reinforcing warning signs, and arranging follow-up within a few weeks can dramatically change outcomes.

Discharge is part of treatment—not an afterthought.

Final Thought

COPD exacerbations don’t fail because we lack effective therapies.

They fail because of oxygen overuse, delayed bronchodilators, excessive steroids, unnecessary antibiotics, missed noninvasive ventilation, and poor transitions of care.

Fixing these mistakes doesn’t require new drugs or complex protocols—just disciplined, thoughtful medicine.

And that’s still very much our job.
