Long-term oxygen therapy provides various benefits, including prolonged survival for severely hypoxic chronic obstructive pulmonary disease (COPD) patients. However, adequate management strategies for home oxygen therapy are not well established in Korea. This study aimed to explore the current situation of home oxygen therapy to provide basic data for developing a strategy for COPD patients on home oxygen therapy.
In this cross-sectional study, we enrolled COPD patients using home oxygen therapy for at least 1 month. Face-to-face interviews were conducted, guided by a structured questionnaire about home oxygen therapy.
A total of 195 patients were enrolled. The mean age was 72.6 ± 9.7 years, and 76.4% of patients were men. The mean modified Medical Research Council, COPD Assessment Test, and EuroQol-5D index scores were 3.4 ± 0.8, 29.7 ± 6.8, and 0.35 ± 0.44, respectively. At rest, patients were prescribed oxygen for 12.5 ± 7.3 hr/day and used 12.9 ± 8.5 hr/day on average. During exercise, the mean duration of prescribed oxygen was 6.6 ± 4.3 hr/day, and the actual use was 1.1 ± 2.9 hr/day. A total of 25.6% of patients used ambulatory oxygen; with financial burden the main reason for nonuse. The mean number of hospitalizations and emergency room visits were 2.5 and 2.6, respectively.
This study revealed low adherence to home oxygen therapy, poor health-related quality of life, frequent hospitalizations, and a high financial burden among COPD patients using home oxygen therapy. The study highlights the need for adequate strategies to improve the quality of home oxygen therapy.
长期氧疗为严重低氧的慢性阻塞性肺疾病（COPD）患者提供了诸多益处，包括延长生存时间。然而，韩国尚未制定出充分的家庭氧疗管理策略。本研究旨在探讨家庭氧疗的现状，为 COPD 患者家庭氧疗策略的制定提供基础数据。
本横断面研究纳入了至少接受 1 个月家庭氧疗的 COPD 患者。通过面对面访谈，使用结构化问卷了解家庭氧疗情况。
共纳入 195 例患者，平均年龄为 72.6±9.7 岁，76.4%为男性。平均改良医学研究委员会呼吸困难量表、COPD 评估测试和欧洲五维健康量表评分分别为 3.4±0.8、29.7±6.8 和 0.35±0.44。静息时，患者处方氧疗时间为 12.5±7.3 小时/天，实际使用时间为 12.9±8.5 小时/天。运动时，处方氧疗时间平均为 6.6±4.3 小时/天，实际使用时间为 1.1±2.9 小时/天。25.6%的患者使用便携式氧气，主要因经济负担而未使用。平均住院和急诊就诊次数分别为 2.5 次和 2.6 次。
本研究揭示了 COPD 患者家庭氧疗依从性低、健康相关生活质量差、频繁住院和经济负担重的现状。研究强调需要制定充分的策略来改善家庭氧疗质量。
