OBJECTIVE: Effectiveness of periodic spirometry in medical monitoring depends on spirometry quality. We describe an intervention on spirometry quality and its impact on accuracy and precision of longitudinal measurements. METHODS: The intervention was conducted from 2005 to 2010 in a monitoring program involving approximately 2500 firefighters. Intervention supported adherence to 2005 American Thoracic Society/European Respiratory Society recommendations through monitoring of spirometry quality and longitudinal data precision, technician training, change of spirometer, and quality control. RESULTS: The percentage of forced vital capacity tests meeting the American Thoracic Society/European Respiratory Society criteria increased from 60 percent to 95 percent and the mean longitudinal forced expiratory volume in 1 second within-person variation decreased from 6 percent to 4 percent. The increased accuracy and precision of measurements and estimated rates of forced expiratory volume in 1 second decline were statistically significant. CONCLUSION: Monitoring of quality and data precision helped to recognize the need for intervention. The intervention improved accuracy and precision of spirometry measurements and their usefulness.
