Patients with COPD and chronic bronchitis had a worse quality of life, symptoms and mental well-being than those patients with chronic airway obstruction, according to study results.
Researchers used the Saint George Respiratory Questionnaire (SGRQ) and the Medical Outcomes Study 36-item short-form survey (SF-36) to evaluate quality of life and symptoms.
The total scores on the SGRQ were greater in the cohort of patients with COPD with CB and without CAO (27 vs. 14.6; P < .001). In patients with COPD and only CB, patients were more troubled with sleep interruptions (110 vs. 139; P < .001) and reported depression more in the SF-36 (182 vs. 421; P < .01).
