Underdiagnosis and Overdiagnosis of Chronic Obstructive Pulmonary Disease

Abstract: Chronic obstructive pulmonary disease (COPD) is regarded as one of the leading causes of morbidity and mortality across the world, yet its proper diagnosis remains a challenge. Community-based population studies conducted in North and South America, Europe, Australia, and Asia have revealed that 10% to 12% of adults aged 40 years or older have evidence of persistent airflow limitation on spirometry, but only 20% to 30% of these subjects have been diagnosed with COPD. These studies collectively suggest that app… Show more

“…The largest contribution of COLD/Can-COLD-related publications may be seen to have advanced knowledge and understanding surrounding appropriate diagnostic approaches and disease characterisation with impact on recommendations for health care services and interventions. More specifically, the larger proportion of studies to date have served to appropriately quantify COPD prevalence and disease determinants 3,4 spirometry testing and prediction equations [5][6][7][8][9] , diagnosis performance and early detection [10][11][12][13][14][15] , novel methods of assessing COPD 16,17 , and COPD clinical impact [18][19][20][21][22] . Consequently, we have elected for this manuscript to summarise key learnings from the CanCOLD study that are relevant to the primary care setting.…”

“…We intentionally studied only patients with known COPD diagnosed by pulmonary function tests, in order to avoid the incorporation of patients over-diagnosed and under-diagnosed of COPD, often present in large clinical databases, which could change the reality of the situation [15][16][17][18].…”
