RATIONALE: ATS estimates that the population attributable risk for COPD due to occupational exposure is 15%. Given the high societal cost, prevention of work-related COPD is a priority. Workplace spirometry monitoring can identify individuals with excessive lung function decline and trigger interventions. This activity depends critically on spirometry quality to minimize measurement error to enable detection of excessive decline due to lung pathology. We have developed software designed to aid health care providers in spirometry monitoring. METHODS: Spirometry Longitudinal Data Analysis (SPIROLA) is a visual and analytical software tool designed to (i) improve the usefulness of longitudinal spirometry data through monitoring its variability; and (ii) facilitate identification of individuals with excessive decline. RESULTS: SPIROLA screen shows the yearly values of absolute and relative pair-wise within-person variance of FEV1 from a workplace monitoring program operational since 1988. Using SPIROLA in 2004, the program management identified spirometry data problems (increased variability) and subsequently introduced intervention measures (NIOSH training, equipment, quality control). The resulting decrease in data variability improves the program s capacity to detect individuals with excessive declines. CONCLUSIONS: SPIROLA software has been demonstrated to be a practical and useful tool in the management of workplace spirometry
