Abstract

Pulmonologists in primary care clinics are positioned between those in tertiary hospitals and general practitioners in clinics and are anticipated to promote hospital-clinic collaboration for patients with chronic obstructive pulmonary disease (COPD). However, the clinical features of patients in primary respiratory clinics are unclear. This multicenter study cross-sectionally compared the characteristics of patients with COPD in a respiratory clinic (n = 69) with those in a university hospital (n = 124). More patients visited the clinic for symptom relief without a referral, whereas more visited the hospital for consultation of abnormal spirometry/computed tomography (CT). The patients in the clinic showed female predilection, higher prevalence of current smokers, severe dyspnea, and concomitant heart failure, and higher CT-measured cross-sectional area ratio of pectoralis muscle to adjacent subcutaneous adipose tissue compared to those in the hospital (all p < 0.05). The observed differences between the two groups suggest the need to establish the role of primary pulmonologists in hospital-clinic collaboration for better COPD management.
