Early spirometry screening in high-risk individuals effectively detects airflow limitation (AL), a key indicator of chronic obstructive pulmonary disease (COPD). This proactive approach identifies many current smokers with AL, enabling timely intervention for COPD management.

Area of Science:

  • Pulmonary Medicine
  • Respiratory Health
  • Public Health Screening

Background:

  • Chronic obstructive pulmonary disease (COPD) progression is currently halted only by early diagnosis and smoking cessation.
  • Identifying individuals with airflow limitation (AL) at high risk for COPD is crucial for intervention.
  • Spirometric screening offers a method for early detection of respiratory impairment.

Purpose of the Study:

  • To evaluate the effectiveness of early airflow limitation (AL) detection through spirometric screening in a high-risk COPD population.
  • To assess the prevalence of AL among smokers aged 40 and above with a significant smoking history.
  • To integrate spirometry results with smoking cessation advice for targeted interventions.

Main Methods:

  • Conducted large-scale, voluntary spirometric screening (measuring forced expiratory volume in one second [FEV1] and forced vital capacity [FVC]) in a population at high risk for COPD.

  • Investigated 110,355 subjects, recording smoking history and providing smoking cessation advice based on spirometry findings.
  • Included current smokers (64%), former smokers (25.1%), and lifelong non-smokers (10.9%), with a focus on smokers aged 40+ with 10 pack-years history.

    • Main Results:

    • Spirometry revealed airflow limitation (AL) in 20.3% of the total investigated subjects.
    • Among high-risk smokers (aged 40+, 10 pack-years history), 23% exhibited airflow limitation.
    • Mild, moderate, and severe AL were detected in 7.6%, 6.7%, and 5.9% of subjects, respectively, while 8.3% showed restrictive ventilatory impairment.

    Conclusions:

    • Large-scale, voluntary spirometry screening is effective in identifying a substantial number of individuals with airflow limitation (AL) within the high-risk COPD population.
    • The study highlights the significant prevalence of AL among current smokers in the targeted demographic.
    • Early detection via spirometry facilitates targeted smoking cessation interventions, potentially slowing COPD progression.
