    Pulmonary physicians often disagree on interpreting pulmonary function test results, impacting patient care. Standardizing criteria for assessing respiratory impairment is crucial for consistent clinical decisions.

    Area of Science:

    • Pulmonary Medicine
    • Clinical Diagnostics

    Background:

    • Pulmonary function tests (PFTs) are essential for diagnosing and managing respiratory diseases.
    • Variability in interpreting PFT results can lead to inconsistent patient management.

    Purpose of the Study:

    • To assess inter-physician agreement in interpreting PFT results.
    • To identify factors contributing to disagreement in PFT interpretation.

    Main Methods:

    • Twenty-six pulmonary physicians interpreted ten consecutive PFTs from a single laboratory.
    • Physicians' assessments of respiratory impairment were collected and analyzed for agreement.

    Main Results:

    • Frequent disagreements were observed among physicians in assessing respiratory impairment.

  • Disagreement is likely linked to diverse criteria used for grading obstructive and restrictive defects.

    • Conclusions:

    • Physician interpretation of PFT data significantly influences patient care.
    • Standardizing interpretation criteria and focusing on numerical data alongside descriptive terms is recommended for improved consistency.
