Although being a rapidly expanding socioeconomical burden worldwide, chronic obstructive pulmonary disease (COPD) is often overlooked because of its insidious progression. Since spirometry is the primary tool for the diagnosis of COPD, physicians should be aware of the disease in any situation where interpreting spirometry. This study was to estimate the prevalence of undiagnosed COPD among patients who underwent spirometry as a preoperative evaluation for elective surgeries. ⋯ The remaining 194 patients with AL (74%) were suspected to have undiagnosed COPD, 90% of which was mild in severity. Only 30 (15%) of these patients appeared to be diagnosed have received a diagnosed as COPD by physician on this occasion. This study testifies that COPD is often unnoticed, and demonstrates that every spirometry, such as in preoperative evaluation, gives a clue to identify affected individuals, for which awareness of the disease is essential.
