Identifying the Knowledge Structure and Trends of Outreach in Public Health Care: A Text Network Analysis and Topic Modeling

Abstract

Outreach programs are considered a key strategy for providing services to underserved populations and play a central role in delivering health-care services. To address this challenge, knowledge relevant to global health outreach programs has recently been expanded. The aims of this study were to analyze the knowledge structure and understand the trends in aspects over time and across regions using text network analysis with NetMiner 4.0. Data analysis by frequency, time and region showed that the central keywords such as patient, care, service and community were found to be highly related to the area, target population, purpose and type of services within the knowledge structure of outreach. As a result of performing topic modeling, knowledge structure in this area consisted of five topics: patient-centered care, HIV care continuum, services related to a specific disease, community-based health-care services and research and education on health programs. Our results newly identified that patient-centered care, specific disease and population have been growing more crucial for all times and countries by the examination of major trends in health-care related outreach research. These findings help health professionals, researchers and policymakers in nursing and public health fields in understanding and developing health-care-related outreach practices and suggest future research direction.

Trend Research on Maritime Autonomous Surface Ships (MASSs) Based on Shipboard Electronics: Focusing on Text Mining and Network Analysis

“…This research used NetMiner4.4.3 (Cyram Inc., Seongnam, Republic of Korea), a software tool used for network analysis and visualization. Along with UCINET and Pajek, NetMiner is a representative tool for social network analysis [35]. A research model was designed for this study, as shown in Figure 2.…”

Crowdfunding from the perspective of young people

“…Crowdfunding from the perspective of young people Journal of Accounting and Investment, 2024 | 174 indirectly shows the factors that attract the most attention from a problem or topic context. Thus, the SNA approach can be used to describe the structure of knowledge related to the appeal of crowdfunding (Park & Park, 2021). Lynn et al (2020) also used SNA to understand effective crowdfunding campaign patterns on Twitter.…”

“…Text analysis is based on SNA aimed at analyzing and understanding the dominant topic of text material in big data (Park & Park, 2021). Network theory, which forms the basis of the SNA approach, explains that everything interrelated can be explained in a network (Wichmann & Kaufmann, 2016).…”

“…Although the basis of SNA is social network theory, which is widely used to reveal the role of actors in networks, in its development, the SNA approach is also used to reveal ideas or topics of a broad issue (Y. Kim & Jang, 2018;Park & Park, 2021).…”

“…In the context of this study, this knowledge structure can also be a picture of the tendency of issues sought, needed, or considered necessary in the issue of crowdfunding success. Thus, understanding the structure of people's knowledge of crowdfunding will provide a more comprehensive understanding of the dominant factors that attract people to contribute to crowdfunding (Park & Park, 2021;H. Zhou & Ye, 2021).…”
