PURPOSE: The National Lung Health Education Program recommends the use of spirometric screening for patients ≥45 years old who report smoking cigarettes, patients with respiratiory symptoms and patients who desire a global health assessment. In this reason, spirometric screening test performed in Health check-up center. It need a standardization of spirometry , however, there are some limitations to perform (ex; time to test or recognition in population who without respiratory symptoms). Purpose: To assess the results and the standardisation of screening spirometry using a desktop spirometer in a health check up center.
METHODS: Method: In a Health check-up center, from April, 2005 to February 2006, who showed air flow limitation in screening spirometry using a desktop spirometer are enrolled. They recheck spirometry in pulmonary function test laboratory.
RESULTS: Of 9350 patients who checked screening spirometry using a desktop spirometer, 728 showed air flow limitations. 594 patients(81.5%) showed restrictive pattern, 112(15.4%) showed obstructive pattern, 22(3%) showed mixed pattern. It showed correlation between FEV1/FVC and smoking amount. (FEV1/FVC≥70 vs. FEV1/FVC<70, smokng amount 22.64±18.31 vs. 20.36±10.78 pyr, p=0.020). The patients with FEV1/FVC<70 who report smoking history did not present dyspnea. Of 728 patinets, 156 rechecked spirometry in pulmonary function test laboratory. 92 patinets(59%) showed nomal flow pattern, 39(25%) showed obstructive pattern, 25(13.1%) showed restrictive pattern. Forced Expiratory Time in health check up center is 5.31±1.69sec, in pulmonary function test laboratory is 6.84±1.14sec(p<0.05).
CONCLUSION: Spirometric secreening test is useful to detect air flow limitation in who report smoking history without respiratory symptoms. But there are need to effort to get spirometry standardisation for accuracy in a health check-up center.
CLINICAL IMPLICATIONS: A desktop spirometry is accurate, however the standardisation is more needed. Spirometric screening test in smokers , regardless of respiratory symptoms, is useful to screen airflow limitation.
