Long-term oxygen therapy (LTOT) improves the survival of patients with hypoxemia due to chronic respiratory diseases. The clinical outcomes of LTOT are strongly associated with patient adherence. To improve the adherence of patients, physicians have focused on the efficacy of LTOT. However, poor adherence may stem from patients' perceptions of LTOT. Herein we evaluated patients' perceptions of LTOT affecting adherence.
We conducted a cross-sectional survey study using descriptive, open, and closed-ended questionnaire. Patients using oxygen therapy (OT) or requiring it but avoiding OT responded to the questionnaires at three university hospitals.
Seventy-nine patients responded to the questionnaires. The number of patients using home and portable OT was 69 (93%) and 37 (46.3%), respectively. Patients with good adherence were 22 (30.1%). Among patients with good adherence, 90.9% used oxygen according to physicians' prescriptions whereas only 37.3% of those with poor adherence followed physicians' prescriptions (p<0.01). The reasons for avoiding using home OT were fear of permanent use (50%), unwanted attention (40%), and lack of symptoms (40%). They avoided portable OT because of unwanted attention (39%), heaviness (31.7%), and lack of symptoms (21.6%).
Patients on LTOT had the perception of the misunderstanding the effects of OT and of psychosocial barriers to initiate or use LTOT. Considering these findings, health professionals need to provide effective education on the purpose of LTOT to improve patient adherence to OT and provide sufficient support for the management of psychosocial barriers in patients using LTOT.
长期氧疗（LTOT）可提高慢性呼吸道疾病所致低氧血症患者的生存率。LTOT的临床疗效与患者的依从性密切相关。为提高患者的依从性，医生们一直关注LTOT的疗效。然而，依从性差可能源于患者对LTOT的认知。在此，我们评估了患者对LTOT的认知对依从性的影响。
我们使用描述性、开放性和封闭式问卷进行了一项横断面调查研究。在三家大学医院，使用氧疗（OT）或需要氧疗但避免使用的患者回答了问卷。
79名患者回答了问卷。使用家庭和便携式OT的患者人数分别为69名（93%）和37名（46.3%）。依从性良好的患者有22名（30.1%）。在依从性良好的患者中，90.9%按照医生的处方使用氧气，而依从性差的患者中只有37.3%遵循医生的处方（p<0.01）。避免使用家庭OT的原因是担心长期使用（50%）、不想引人注意（40%）和没有症状（40%）。他们避免使用便携式OT是因为不想引人注意（39%）、觉得笨重（31.7%）和没有症状（21.6%）。
接受LTOT的患者存在对OT效果的误解以及启动或使用LTOT的心理社会障碍。考虑到这些发现，卫生专业人员需要就LTOT的目的提供有效的教育，以提高患者对OT的依从性，并为使用LTOT的患者管理心理社会障碍提供充分的支持。
