Abstract:

Objective Under the guidance of the Social Ecosystems Theory（SET） framework，this study explores the experience of social isolation among patients with chronic obstructive pulmonary disease（COPD），providing a basis for the development of targeted clinical interventions. Methods This study employed purposeful sampling methods. Semi-structured interviews were conducted from April to July 2024 with patients diagnosed with COPD at a tertiary hospital in Shanxi Province，China，who met the inclusion and exclusion criteria. Data were analyzed using Colaizzi’s seven-step analysis method and NVivo 12.0 software. Results This study involved in-depth interviews with 15 patients suffering from COPD，totaling approximately 405 minutes of interview time and yielding over 40，000 words in transcribed text. Totally 3 main themes and 9 sub-themes were distilled，among which the microsystem level reflects the intricate interplay of individual experiences（physical functional limitations，severe negative emotions，heightened emotional imbalance，and weakened social roles）；the mesosystem level pertains to the support and challenges from family and social networks（intense need for familial emotional support，widening social gaps in interactions with friends and relatives，and pronounced interpersonal communication barriers）；the macrosystem level involves the integrated influence of societal and policy environments（restricted living conditions and urgent demands for policy support and service accessibility）. Conclusion The social isolation experienced by patients with COPD manifests in multiple dimensions of experience. It is necessary to develop interdisciplinary and multi-level comprehensive intervention strategies for the future，to create more social opportunities and emotional connections for patients，thereby improving their quality of life.
