A large cohort study found that using the GOLD criteria (FEV1/FVC less than 70%) for diagnosis of chronic obstructive pulmonary disease (COPD) in U.S. adults 65 years and older was more sensitive for COPD-related obstructive lung disease than using the ATS criteria (FEV1/FVC less than the LLN).6 This finding was based on evidence that adults who met the GOLD criteria but not the ATS criteria (FEV1/FVC less than 70% but greater than the LLN) had greater risk of COPD-related hospitalization (hazard ratio = 2.6; 95% confidence interval, 2.0 to 3.3) and mortality (hazard ratio = 1.3; 95% confidence interval, 1.1 to 1.5).7 Another cohort study looking at adults 65 years and older found that, compared with the ATS criteria, the GOLD criteria had higher clinical agreement with an expert panel diagnosis for COPD and better identified patients with clinically relevant events (e.g., COPD exacerbation, hospitalization, mortality).7 Until better criteria for the diagnosis of COPD are found, physicians should use the GOLD criteria to diagnose obstructive lung disease in patients 65 years and older with respiratory symptoms who are at risk of COPD (i.e., current or previous smoker).6,7, Other studies have found that using the GOLD criteria can miss up to 50% of young adults with obstructive lung disease and leads to overdiagnosis in healthy non-smokers.8,9 Based on these studies, physicians should use the ATS criteria to diagnose obstructive lung disease in patients younger than 65 years regardless of smoking status, and in nonsmokers who are 65 years and older.8,9, The physician must determine if the FVC is less than the LLN for adults or less than 80% of predicted for those five to 18 years of age, indicating a restrictive pattern.3,10,11 The LLN can be determined using the calculator at http://hankconsulting.com/RefCal.html.
