Purpose: This study aimed to examine the distribution and combination patterns of intrinsic capacity impairment and analyze its association with physical function among vulnerable older adults who participated in a visiting healthcare program at a public health center. Methods: This cross-sectional secondary analysis used data from older adult participants of a visiting healthcare program that was conducted at four public health centers. Intrinsic capacity impairment was assessed across six domains: cognition, mobility, depressive symptoms, sensory function, nutritional status, and oral function. Physical function was measured using the grip strength, balance, timed up and go (TUG) test, and instrumental activities of daily living (IADL). The data were analyzed to identify the prevalence and combinations of intrinsic capacity impairment and examine its association with physical function. Results: In total, 87.6% of the participants showed impairment in at least one domain of intrinsic capacity. Impairment of oral function was the most prevalent (42.6%), followed by depressive symptoms (34.9%); cognitive (33.1%), mobility (24.3%), and sensory (18.3%) impairments; and malnutrition (8.3%). Impairment of oral function frequently co-occurs with cognitive, psychological, and mobility impairments. Intrinsic capacity impairment was significantly associated with the grip strength, balance, TUG test, and IADL, and higher levels of intrinsic capacity impairment were associated with lower physical function. Conclusion: Intrinsic capacity impairment is closely associated with physical function in community-dwelling older adults. Comprehensive assessment and integrated management of intrinsic capacity, including oral health, are necessary to prevent functional decline and support aging in place.

Purpose: This study examined changes in media discourse on visiting nursing provided by public health centers before and after the implementation of the Community Integrated Care Policy using topic modeling and keyword network analysis. Methods: In this computational content analysis, news articles related to visiting nursing provided by public health centers, visiting health care services, home-based health management, community integrated care, and integrated medical and long-term care support were collected from BIGKinds. The dataset was divided into the periods before and after policy implementation. After text preprocessing, term frequency-inverse document frequency analysis, latent Dirichlet allocation topic modeling, and keyword network analysis were performed. Results: Before policy implementation, major topics included care for vulnerable populations, visiting health care programs, long-term care and home-based services, community linkage for discharged patients, and community care policy initiatives. Media discourse focused on public health centers, nurses, chronic disease management, case management, blood pressure measurement, health counseling, and prevention. After policy implementation, major topics shifted to integrated medical and long-term care support, home-based services, community linkage for discharged patients, and community care policy initiatives. Media discourse primarily focused on public health centers, nurses, chronic disease management, case management, blood pressure measurement, health counseling, and prevention. Keyword network analysis indicated that nurses were portrayed as both direct providers of visiting health care services and coordinators linking integrated management, community resources, home-based care, and care services. Conclusion: Media discourse shifted from visiting health care and chronic disease prevention toward integrated care, home-based medical care, and community-based care coordination. Policy support is needed to clarify nurses' roles and strengthen education, workforce capacity, and institutional systems.
