    Summary

    Computerized reporting of pulmonary function tests shows good agreement with expert physicians. While physicians had fewer disagreements, the computer system offers immediate availability and comparable usefulness in daily practice.

    Area of Science:

    • Pulmonary Medicine
    • Medical Informatics
    • Diagnostic Reporting

    Background:

    • Pulmonary function tests (PFTs) are crucial for diagnosing respiratory conditions.
    • Manual interpretation of PFT reports can be time-consuming and subject to inter-observer variability.
    • Automated reporting systems aim to improve efficiency and consistency in PFT interpretation.

    Purpose of the Study:

    • To compare the accuracy and consistency of computer-generated PFT reports with those of consultant chest physicians.
    • To evaluate the agreement between physicians and between physicians and the computer system.
    • To assess the utility of an on-line computer reporting system in a routine clinical setting.

    Main Methods:

    • Sixty sets of PFT numerical results were independently reported by five consultant chest physicians.

  • These reports were compared against reports generated by an on-line computer reporting system.
  • Individual and consensus opinions from physicians were used as benchmarks for comparison.

    • Main Results:

    • Good agreement was observed among chest physicians and between physicians and the computer system.
    • The computer system's decisions differed from the consensus opinion in 4.6% of cases.
    • Physicians' deviations from consensus ranged from 2.9% to 4.6%, with more mistakes noted under test conditions.

    Conclusions:

    • Computerized PFT reporting demonstrates comparable usefulness and consistency to expert physician reports in routine practice.
    • The computer system offers immediate availability, a significant advantage over manual reporting.
    • While physicians had fewer genuine disagreements, the computer's efficiency and accuracy make it a valuable tool.
