Background: Chronic obstructive pulmonary disease (COPD) is marked by severe physical symptoms, impaired quality of life, and high psychological distress. Despite its impact, the identification of not only physical but also psychosocial and existential issues in the clinic lags behind that of other patient groups. Methods: This study aimed to assess physical, psychosocial, and existential issues among patients with COPD using a patient-reported outcome measure for general palliative care (the 'PRO-Pall') in a Danish outpatient clinic. We included 115 adults with COPD who completed the PRO-Pall either electronically or in the clinic. Sociodemographic and illness-related data were retrieved from their electronic health records. Results: We found that shortness of breath, tiredness, and difficulty walking were predominant physical issues. Worry about change in social roles was the most frequently reported psychosocial issue, while existential issues were reported by approximately one in ten patients. Most patients (44.5%) felt able to share their feelings with family or friends, and a majority (62.2%) felt their illness-related issues were addressed satisfactorily. Females expressed a greater need for rest and males more frequently reported intimacy issues. Higher COPD-impact on life measured by the COPD Assessment Test was associated with lower ratings on the quality-of-life item of the PRO-Pall independent of age, gender, lung function, and smoking status. Conclusions: Patients reported issues in physical, psychosocial, and existential dimensions of the PRO-Pall. The PRO-Pall shows potential as a broader alternative to measures that focus mainly on physical issues.
