Chronic obstructive pulmonary disease (COPD) is a common disability, largely encountered in the elderly population, in whom it causes significant morbidity and mortality. The general perception of health professionals is that COPD is often a self-inflicted disorder affecting the more socio-economically disadvantaged segment of the population with significant comorbidity. COPD is the least funded in terms of research in relation to illness burden compared with other chronic diseases. ⋯ Therefore, pulmonary function including spirometry should be used to make the diagnosis of COPD but not as a monitor of efficacy of treatment. Assessment of severity of COPD and improvement with treatment modalities is best done with dynamic exercise testing such as 6-minute walk tests and incremental shuttle walk tests or with the administration of disease-specific physical disability and quality-of-life questionnaires. Most COPD research does not specifically target the older COPD patients and these patients may merit special consideration for their optimum assessment and management.
