• Spirometry Test Results in Primary Care Practices

    Study Description and Methods

    This randomized clinical trial was designed to assess the accuracy of spirometry testing completed in the family physicians’ office using new simplified equipment. The study also explored the impact of using spirometry on physician-assigned disease severity and care decisions. The study was conducted in family physician offices for five months to assess the ability of the practices to continue to produce high quality spirometry testing over an extended period, and to determine the role and potential value of spirometry in family physicians’ practices and the support requirements for maintaining high quality testing.

    Specific Aims and Objectives

    The purpose of this study was to assess the technical adequacy, accuracy of interpretation, and impact of office spirometry testing in the care of patients with asthma or COPD.


    This project was conducted from January 2004 through December 2004

    Key Findings and Publications

    Most family physician’s offices were able to perform technically adequate spirometery testing. Interpretation of the test results may benefit from additional training, or longitudinal training such as rapid feedback regarding any perceived problems. The use of spriometery changed treatment in a significant minority of patient’s care.
