Perspectives From COPD Subjects on Portable Long-Term Oxygen Therapy Devices

Area of Science:

• Pulmonary Medicine
• Biomedical Engineering
• Patient-Reported Outcomes

Background:

• Chronic Obstructive Pulmonary Disease (COPD) patients requiring oxygen therapy often face mobility challenges.
• Existing long-term oxygen therapy (LTOT) devices can restrict physical activity, potentially diminishing quality of life.

Purpose of the Study:

• To investigate the perceived limitations patients with COPD experience with their long-term oxygen therapy (LTOT) devices.
• To understand how LTOT device characteristics impact patient mobility and quality of life.

Main Methods:

• Qualitative analysis of 311 open-ended survey responses from oxygen-dependent COPD patients.
• Thematic analysis using NVivo software to identify patterns in patient experiences with LTOT devices.
• Cluster analysis to explore relationships between concepts related to LTOT device use.

Main Results:

• Patients reported decreased mobility, leading to feelings of reduced autonomy and social isolation.
• Portable oxygen cylinders perceived as heavy and cumbersome negatively impacted quality of life.
• Concerns about insufficient breathing support and device run-time caused anxiety; some patients opted for costly liquid oxygen for better mobility.

Conclusions:

• Inadequate physical and technical features of portable oxygen devices may lead to decreased mobility in COPD patients.
• This reduced mobility can result in adverse outcomes for oxygen-dependent individuals with COPD.
