    Spirometric screening in general medicine clinics is feasible and rapid, costing less than a dollar per patient. This pulmonary function testing identifies significant respiratory abnormalities, especially in current smokers, aiding smoking cessation efforts.

    Area of Science:

    • Pulmonary Medicine
    • Clinical Screening
    • Respiratory Health

    Background:

    • Spirometric screening in general medicine settings is underutilized.
    • Early detection of respiratory abnormalities is crucial for intervention.
    • Assessing the practical application of pulmonary function tests in primary care is needed.

    Purpose of the Study:

    • To evaluate the feasibility and yield of spirometric screening in a general medicine clinic.
    • To determine the prevalence of pulmonary function abnormalities in a diverse patient population.
    • To assess the utility of spirometry in identifying undiagnosed respiratory conditions and encouraging smoking cessation.

    Main Methods:

    • A prospective study involving 354 randomly selected patients in a general medicine clinic.

  • Patients completed a respiratory symptom questionnaire.
  • Pulmonary function tests (spirometry) were performed on all participants.
  • Main Results:

    • Spirometry screening was rapid (approx. 2 minutes) and inexpensive ($.95/patient).
    • Former smokers who quit due to symptoms showed higher abnormality rates than expected; lifelong smokers showed lower rates (P<0.001).
    • 53% of current smokers had abnormal pulmonary function tests, with 42% having no severe symptoms, highlighting potential for intervention.

    Conclusions:

    • Spirometric screening is a practical and cost-effective tool for general medicine clinics.
    • Pulmonary function tests can identify a substantial number of patients with respiratory abnormalities, including asymptomatic current smokers.
    • The findings support using spirometry to motivate smoking cessation and manage respiratory health in primary care settings.
