ABSTRACT
In clinical practice, clinicians mainly focus on Chronic Obstructive Pulmonary Disease (COPD) exacerbations and symptoms, while patients may prefer to evaluate periods free of COPD exacerbations and deteriorated symptoms. The latter would suit the positive health approach that centralizes people and their beliefs. We aimed to identify patient characteristics and health outcomes relating to 1) COPD exacerbation-free days; 2) days with no more symptoms than usual; and 3) combined COPD exacerbation and comorbid flare-up-free days (i.e. chronic heart failure, anxiety, depression flare-ups) using negative binomial regression analyzes. Data were obtained from two self-management intervention trials including COPD patients with and without comorbidities. 313 patients (mean age 66.0 years, 63.6% male, 68.7% comorbidity) were included. Better baseline chronic respiratory questionnaire (CRQ) fatigue (incidence rate ratio (IRR) = 1.03 (95% CI 1.01-1.05), p = 0.02) and mastery scores (IRR = 1.03 (95% CI 1.00-1.06), p = 0.04) and fewer courses of antibiotics (IRR = 0.95 (95% CI 0.94-0.96), p < 0.01) were related to more COPD exacerbation-free days. Additionally, better baseline CRQ fatigue (IRR = 1.05 (95% CI 1.00-1.10), p = 0.04) and mastery scores (IRR = 1.06 (95% CI 1.00-1.12), p = 0.04), fewer courses of antibiotics (IRR = 0.94 (95% CI 0.91-0.96), p < 0.01), and improved CRQ dyspnea scores over 12 months of follow-up (IRR = 1.07 (95% CI 1.01-1.12), p < 0.01) were correlated to more days free of deteriorated symptoms. Less baseline dyspnea (modified Medical Research Council score) (IRR = 0.95 (95% CI 0.92-0.98), p < 0.01) and fewer courses of antibiotics (IRR = 0.94 (95% CI 0.93-0.95), p < 0.01) were associated with more combined COPD exacerbation and comorbid flare-up-free days. Healthcare professionals should be aware that less fatigue and better mastering of COPD relate to more exacerbation and symptom-free time in COPD patients.
