Although spirometry is a simple test and commonly performed in a variety of settings, accurate results depend on careful technique, proper equipment calibration and maintenance. The American Thoracic Society (ATS) and European Respiratory Society (ERS) have recommended several procedures to reduce variability in spirometry test results, including the weekly testing of flow volume measurements and biologic normal subjects.
Under the DAP spirometry quality control (QC) program, the results of these QC procedures, submitted to the DAP twice per year, give an indication of any areas of concern with the spirometer or performance of the tests. This is the avenue for which facilities and physicians performing spirometry and flow volume loops are accredited.
All facilities and physicians performing spirometry and flow volume loops must be accredited by the DAP to perform the service in British Columbia, regardless of their revenue stream or whether they charge for the service or not.
Physicians who are currently performing spirometry or spirometry and flow volume loop testing and are not accredited must contact the DAP at firstname.lastname@example.org for more information about applying for accreditation.
