As the aging society develops, multimorbidity is increasingly prevalent in an increased number of older adults, which imposes a heavy treatment burden on the group, but the composition of treatment burden of elderly patients with chronic comorbidity in China is not clear.

To understand the real experience of treatment burden in elderly patients with multimorbidity, providing a theoretical basis for promoting the research on treatment burden in China.

By use of purposive sampling, 21 older inpatients with multimorbidity were selected from three hospitals (one is primary level, another is secondary and another is tertiary) in Chengdu from January to June 2021. Individual, face-to-face, in-depth, semi-structured interviews were utilized to collect their experiences of treatment burden, and the data were recorded, and analyzed using Colaizzi's method of data analysis.

Of the participants, eight were women, and 13 were men; 10 were selected from the tertiary hospital, seven from the secondary hospital, and four from the primary hospital. Six themes were summarized: economic burden, drug burden, self-management burden, medical service burden, social burden and psychological burden.

Taken overall, the treatment burden was relatively heavy in older inpatients with multimorbidity. To reduce the treatment burden and improve the efficacy in this group, it is recommended that medical workers should pay attention to their treatment burden, and formulate individualized treatment plan for them.

随着社会老龄化程度的逐渐加深，老年人口数量逐渐增多，老年慢性病共病现象日益普遍。慢性病共病给老年患者带来了较重的治疗负担，但当前国内老年慢性病共病患者治疗负担组成尚不明确。

深入了解老年慢性病共病患者治疗负担的真实体验，为促进国内治疗负担的研究提供理论依据。

采用目的抽样法选择2021年1—6月在成都市1所三级医院、1所二级医院、1所一级医院住院的老年慢性病共病患者21例，采用面对面、半结构式深度访谈法进行访谈，了解其治疗负担，并按照Colaizzi现象学资料的7步分析法对访谈资料进行整理与分析。

共访谈了21例老年慢性病共病患者，其中女8例、男13例，来自三级医院10例、二级医院7例、一级医院4例。提炼出老年慢性病共病患者治疗负担体验的6个主题：经济负担、药物负担、自我管理负担、获得医疗服务负担、社交性负担、心理负担。

老年慢性病共病患者在疾病治疗过程中治疗负担较重，医护人员需要关注患者在治疗疾病过程中所承受的治疗负担，制定个体化的治疗方案，尽可能地将慢性病共病患者的治疗负担降至最低，提高患者的治疗效果。
