Objective. Peer support is a concept of substantial significance to health scientists and practitioners today due to its focus shifting from disease treatment to health promotion. Effective incorporation peer relationships in support-enhancing interventions could improve quality care and health outcomes. More and more cases of chronic obstructive pulmonary disease (COPD) have been diagnosed in nonsmokers. In this study, the effects of peer-support nursing intervention on the pulmonary function and quality of life of nonsmoking patients with COPD were investigated. Methods. A total of 100 COPD nonsmoking patients admitted to our hospital from October 2018 to October 2020 were selected as study subjects. All nonsmoking patients were in accordance with the guidelines of COPD diagnosis and treatment issued by the Respiratory Medicine Branch of Chinese Medical Association, and they were not in the habit of smoking. According to the different interventions, the nonsmoking patients were divided into the control group (n = 50) and the observation group (n = 50). Among them, nonsmoking patients in the control group received routine care, and nonsmoking patients in the observation group received routine care and peer-support nursing. The difference on the scores of social support, self-management efficacy, healthy lifestyle, and the distance of six-minute walking were to be compared between the two groups before and after the intervention. Results. There was no significant statistical difference on the general information between the two groups in terms of age, gender, and course of disease (). Before intervention, the social support score involving subjective support, objective support, utilization of support, and total score revealed slight difference between the two groups (). However, after the intervention, the subjective support, utilization of support, and total score remained statistically different between the two groups (), and the objective support showed no significant difference between the two groups (). Before intervention, there was no statistical difference in the self-management efficacy scores such as positive attitude, stress reduction, self-decision-making, and total score between the two groups (). After the intervention, the two groups indicated statistical difference in the self-management efficacy scores (). Before intervention, there was no significant difference between the two groups in the healthy lifestyle score in terms of health responsibility, self-realization, interpersonal support, and stress management (), and the abovementioned outcome measures indicated significant difference between the two groups after intervention (). There was no statistical difference in six-minute walking distance between the two groups before the intervention (), but after the intervention, the observation group revealed a significantly longer distance of six-minute walking compared to the control group (). Conclusion. These data suggest that peer-support nursing intervention can effectively improve pulmonary function and quality of life of nonsmoking patients with COPD.

同伴支持护理干预对非吸烟 COPD 患者肺功能和生活质量的益处

客观。同伴支持对于当今的健康科学家和从业者来说是一个具有重大意义的概念，因为它的重点从疾病治疗转向了健康促进。有效地将同伴关系纳入支持增强干预措施可以改善优质护理和健康结果。越来越多的慢性阻塞性肺病 (COPD) 病例在非吸烟者中被诊断出来。本研究探讨同伴支持护理干预对不吸烟COPD患者肺功能和生活质量的影响。方法. 选取2018年10月至2020年10月我院收治的COPD不吸烟患者100例作为研究对象。所有不吸烟患者均符合中华医学会呼吸内科分会发布的COPD诊疗指南，无吸烟习惯。根据干预措施的不同，将不吸烟患者分为对照组（n  =50）和观察组（n = 50)。其中，对照组不吸烟患者接受常规护理，观察组不吸烟患者接受常规护理和同伴支持护理。比较干预前后两组在社会支持、自我管理效能、健康生活方式、六分钟步行距离等方面得分的差异。结果。两组在年龄、性别、病程等方面的一般资料差异无统计学意义（）。干预前，主观支持、客观支持、支持利用和总分的社会支持评分显示两组之间存在微小差异（）。然而，干预后，两组的主观支持、支持利用和总分仍然存在统计学差异（），客观支持度在两组之间没有显着差异（）。干预前，两组在积极态度、减压、自我决策、总分等自我管理效能得分方面差异无统计学意义（）。干预后，两组自我管理效能评分有统计学差异（）。干预前，两组在健康责任、自我实现、人际支持、压力管理等方面的健康生活方式评分均无显着差异。），上述结果测量表明干预后两组之间存在显着差异（）。干预前两组6分钟步行距离差异无统计学意义（），但干预后，观察组的六分钟步行距离明显长于对照组（）。 结论。这些数据表明，同伴支持护理干预可以有效改善非吸烟COPD患者的肺功能和生活质量。
