In the face of the serious challenges posed by the high prevalence of chronic diseases among the elderly and the coexistence of multiple chronic diseases, the health problems of community-dwelling elderly people' with multimorbidity require urgent attention. The comorbidity management model is being explored and practiced. Disease experience, as self-reported health information from patients, is expected to become a key component of the patient-centered community multimorbidity management model.

This study aimed to gain a deeper understanding of the real disease experience of community-dwelling elderly people with multimorbidity and provide a basis for personalized health management and supportive strategies of the group.

This study used purposive sampling and maximum difference sampling to select eligible interviewees from four communities under the jurisdiction of a community health service center in Zhengzhou City from August to September in 2022. Based on the principle of information saturation, 20 subjects were ultimately included. Based on the research objective, literature review, and expert consultation results, the preliminary interview outline was formulated, and the final interview outline was determined after interviewing 2 patients. Semi-structured interviews were conducted with the study participants, guided by the phenomenological research methodology. Golaizzi analysis was used to analyse the data.

Four themes and eleven sub-themes had been extracted from this study, including mainly long-standing symptomatic distress (physical dysfunction, fatigue, sleep disorders, and pain), negative psychological experiences (feelings of helplessness and worry about future life, reduced sense of social value and self-identity, and loneliness with altered social activities), positive mindset of coexisting harmoniously with multimorbidity (being grateful for being satisfied, and positively adapting), and aspirations in times of adversity (hoping for improvement in functioning, and seeking multi-directional social support) .

Physical dysfunction, sleep disturbances, fatigue, and pain are the most concerning health disturbances for community-dwelling elderly people with multimorbidity. The symptom management and multiple social support of the multimorbidity need to be strengthened. In the future, it is expected that multidimensional data would be used for dynamic health assessment to explore the common and individual patterns of multimorbidity, and to achieve precise management and intervention of elderly multimorbidity in the community.
