Diagnosing COPD in general practice

Abstract

COPD prevalence is likely to be underestimated in the UK. Anne Rodman explores the current evidence base for diagnosing COPD Chronic obstructive pulmonary disease (COPD) is an umbrella term for several different pathological processes in the lungs of susceptible individuals. COPD should be considered in any patient who has symptoms and a history of exposure to risk factors for the disease. The cornerstone of COPD diagnosis is to identify risk factors for this preventable condition, recognise and investigate any symptoms that are not commonly found in COPD, and confirm that obstruction is present with correctly performed and interpreted spirometry. This article explores the current evidence base for diagnosing COPD, how to differentiate it from asthma and other conditions with similar symptoms, and the rationale for specialist referral.
