Abstract

Chronic obstructive pulmonary disease is frequently undiagnosed. The U.S. Preventive Services Task Force recommends against routine screening of asymptomatic individuals with spirometry. However, case finding strategy is encouraged instead. Questionnaires to identify at risk individuals are feasible and mostly available method. In addition to questionnaire, simple instruments reflecting lung function such as peak flow or COPD-6 are commonly used. There is an attempt to identify a group of individuals who could progress to COPD so that better understand mechanisms of disease development and where disease-modifying interventions are most likely to be successful. An operational definition of the group, early COPD, has recently been proposed. Assessment methods of early COPD are developing area. The symptom of chronic bronchitis in the absence of air flow limitation can be a marker of early disease. New parameters of spirometry and Forced Oscillation Technique / Impulse Oscillometry System are promising tool for early recognition of small airway disease in the absence of conventional air flow limitation. Computed tomography is good assessment tool for detecting early changes of emphysema and small airway disease.
