Topic Modeling and Keyword Network Analysis of News Articles on Visiting Nursing Provided by Public Health Centers Before and After the Implementation of the Community Integrated Care Policy
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.
