目的 对老年慢性阻塞性肺疾病（COPD）患者的看护者的疾病相关认知行为进行调查，并分析其对患者生活质量的影响。方法 以出院诊断为中度COPD 的57例老年患者及其看护者作为调研对象。自行设计看护问卷考量看护者的认知行为，内容涉及对患者疾病和治疗的了解程度、用药和肺康复训练监督行为、陪同检查和治疗行为以及鼓励患者获得康复行为等方面。采用圣乔治呼吸问卷对COPD患者的生活质量进行测评。结果 57名被调查的看护者中， 5名（8.78%）看护者对患者的疾病和治疗完全不了解；分别有8名（14.04%）和27名（47.37%）看护者对患者用药和肺康复训练未实施监督；12名（21.05%）看护者从未陪同患者接受检查和治疗，19名（33.33%）看护者对患者获得康复从未给予鼓励。看护问卷得分平均为（6.81±3.47）分，患者生活质量总分平均为（46.30±20.10）分，相关性分析显示两者呈显著负相关性（r=－0.49, P<0.01）。结论 老年COPD患者的看护者对疾病的相关认知行为有待提高，积极看护对患者生活质量的改善具有促进作用。

Objective To investigate the effects of cognition and behaviors of caregivers on quality of life in elderly patients with chronic obstructive pulmonary disease (COPD). Methods Fifty-seven elderly patients with moderate COPD and their caregivers were surveyed. Caregiver questionnaire was designed to investigate the cognition and behaviors of caregivers, which concerned the cognition of disease and treatment, behavior of monitoring of medication and pulmonary rehabilitation, behavior of accompanying of examination and treatment, and behavior of encouragement of rehabilitation. St. George's Respiratory Questionnaire was adopted to investigate the quality of life of patients. Results Among the 57 caregivers, 5 (8.78%) knew nothing about COPD and treatment, 8 （14.04%） never monitored medication, 27 （47.37%） never monitored pulmonary rehabilitation, 12 （21.05%）never accompanied patients to take examinations and treatment, and 19 （33.33%） never encourage patient to attend pulmonary rehabilitation. The mean score of caregiver questionnaire was （6.81±3.47）, the mean score of quality of life was （46.30±20.10）, and there was significantly negative relationship between them （r=－0.49, P<0.01）. Conclusion There is much room for improvement for the cognition and behaviors of caregivers for elderly patients with COPD, and effective care may improve the quality of life of patients.
