Summary
Adherence to supplemental oxygen therapy for hypoxemic chronic obstructive pulmonary disease (COPD) is complex, with patients often shifting between as-needed, part-time, and full-time use. Improving adherence requires addressing physical, social, and psychological barriers to oxygen use.
Area of Science:
- Pulmonary Medicine
- Respiratory Therapy
- Patient Adherence Studies
Background:
- Hypoxemic chronic obstructive pulmonary disease (COPD) necessitates long-term supplemental oxygen therapy for many patients.
- Understanding patient adherence patterns is crucial for optimizing treatment outcomes in COPD management.
Purpose of the Study:
- To describe and explain the diverse patterns of adherence to supplemental oxygen therapy among individuals with hypoxemic COPD.
- To identify factors influencing adherence and the challenges faced by patients using oxygen.
Main Methods:
- A qualitative case-series study was conducted with community-dwelling, English-speaking individuals with hypoxemic COPD using supplemental oxygen.
- Data were collected through semistructured interviews, alongside objective measures like FEV1 and patient-reported outcomes (St. George's Respiratory Questionnaire, Brief Symptom Inventory).
Main Results:
- Three distinct adherence patterns emerged: as-needed, part-time, and full-time oxygen use.
- Adherence patterns often evolved over time, reflecting patients' efforts to balance health, symptoms, function, and social life, frequently involving personal compromises.
- Increased adherence over time was observed, often linked to significant personal sacrifices.
Conclusions:
- Adherence to oxygen therapy presents significant challenges, including physical difficulties, social stigma, perceived lack of benefit, and fear of side effects.
- Understanding the adaptation process and actively addressing these barriers are essential for improving supplemental oxygen therapy adherence in COPD patients.
