- W2906079749 abstract "Background: Obstructive airway diseases (OADs) mainly asthma and chronic obstructive pulmonary disease (COPD) are the two common diseases associated with shortness of breath (SOB) symptoms. Objective: To compare physician-diagnosis of asthma and COPD among community patients with SOB and with prescribed inhalers to spirometrically-defined diagnosis or expert consensus based on ATS/ERS standard guidelines. Method: 328 of eligible SOB patients were identified through community pharmacies in Edmonton and Saskatoon, in Canada. Full pre and post-bronchodilator PFT were performed and diagnosis subsequently determined based on guideline-derived criteria approved by three expert physicians. Result: 45.4% of patients had a diagnosis of asthma and 29.6% COPD. Subjects were Caucasian (86%), female (57%), and had a postsecondary education (49%) and with a median age of 50 years. Only 40% of patients had prior PFT performed to provide a diagnosis from a family-care physician. Self-reported medications for management included SABA (74.1%), inhaled corticosteroids (28.0%), and combination inhaler products (35%). Measures of agreement ( that is, sensitivity (Sens) and specificity(Spec)) of physician-diagnosis with guideline-derived diagnosis were: asthma (Sens=71%, Spec=51%, Kappa=0.22, p=0.001), and COPD (Sens=28%.; Spec=95%, Kappa=0.28, p=0.001). Conclusion: Significant disagreement exists between physician-diagnosis and guideline-derived diagnosis among management of community patients with SOB symptoms. Most patients are prescribed inhalers without a PFT diagnostic workup. This may be in part due to the inadequate understanding of PFT interpretation and usage by family-care physicians." @default.
