COPD prevalence and the differences between newly and previously diagnosed COPD patients in a spirometry program.

Area of Science:

• Pulmonology
• Primary Care Medicine
• Epidemiology

Background:

• Chronic Obstructive Pulmonary Disease (COPD) is a significant public health concern, often underdiagnosed in primary care settings.
• Early detection of COPD is crucial for timely intervention and management to slow disease progression.

Purpose of the Study:

• To determine the prevalence and severity of COPD within a primary care population undergoing spirometry.
• To compare characteristics of newly diagnosed COPD patients versus those with a previous diagnosis.

Main Methods:

• A spirometry program was implemented across 15 primary care centers.
• 1,526 individuals over 30 years old, willing to undergo spirometry, were included in the study.

Main Results:

• COPD prevalence was 18.4%, with 69.0% of cases being newly diagnosed.
• Most identified COPD cases were GOLD stages I and II.
• COPD diagnosis correlated with male gender, older age, childhood respiratory infections, smoking history (>10 pack-years), and symptoms like cough and dyspnea. Newly diagnosed patients were younger and less symptomatic.

Conclusions:

• Primary care spirometry programs are effective in identifying a substantial number of undiagnosed COPD patients, especially in early disease stages.
• Newly diagnosed COPD patients tend to be younger and exhibit fewer symptoms, underscoring the value of proactive screening.
• These findings advocate for the integration of spirometry programs into primary care to facilitate early COPD detection and management.
