Low awareness of COPD among physicians

Area of Science:

• Pulmonary Medicine
• Respiratory Health
• Diagnostic Screening

Background:

• Early identification of chronic obstructive pulmonary disease (COPD) is vital for preventing disease progression and respiratory failure.
• Smoking cessation programs are more effective when initiated early in the disease course.

Purpose of the Study:

• To determine the prevalence of undiagnosed chronic obstructive pulmonary disease (COPD) among current smokers.
• To assess the gap in COPD diagnosis within a high-risk population.

Main Methods:

• A screening procedure was conducted involving current smokers (≥8 cigarettes/day) identified through physician-certified sick leave exceeding two weeks.
• Lung function tests (spirometry) were performed on 3887 participants to diagnose COPD based on European Respiratory Society (ERS) guidelines.

Main Results:

• 17.3% (674/3887) of participants were diagnosed with COPD.
• Only 17.3% (103/674) of those with COPD had a prior physician diagnosis.
• Over 80% of COPD patients identified had no previous diagnosis, despite being on sick leave.

Conclusions:

• A significant proportion of current smokers have undiagnosed COPD.
• Increased awareness and routine spirometry for smokers over 40 are necessary for early COPD diagnosis.
• Spirometry is essential for accurate COPD diagnosis, not solely relying on reported symptoms.
