Background: Information technology innovation is needed in various fields, including health. In the health sector, technological innovations can be applied to patient care, hospital management and research. Technological innovation can be applied to various hospital activities, from patient data collection to cleaning staff activities. Various innovations are needed to simplify health service activities to make services more effective and efficient. The purpose of the study was to explore the trend of technology use and innovation in health care services in hospitals by analyzing network visualization, overlay visualization, and density visualization on the topic through bibliometric analysis. Main body: In this research, bibliometric analysis was used. Records were identified through a database search at https://app.dimensions.ai/. The data obtained was then selected further by the PRISMA flow diagram. Papers were limited to publication years 2020-2023. The publication type is the article only, on the other hand, book chapters, thesis and proceeding publications are excluded. Data were analyzed using VOSviewer, and then reviewed by co-occurrence and co-authors. From the network visualization, it was identified that there were 199 items divided into 8 clusters with 9,504 links with a total link strength of 54,785. After identifying the clusters, the trends of technology use and innovation in health care services in hospitals were artificial intelligence, digital health technology, electronic health records, health information technology, smart health, telemedicine, virtual care, communication technology, electronic medical records and health care delivery. From the overlay visualization, it was indicated that the newest topics that were widely researched related to this theme were digital health service, digital transformation, digital health technology, digital tools, and telehealth service. From density visualization, it was indicated that topics that were rarely researched related to trends of technology use and innovation in healthcare services in hospitals were communication technology, healthcare organizations, and digital solutions. Conclusion: Technological developments have had a major impact on improving the quality of services in hospitals. Health professionals need to develop and improve their competencies so that they can continue to keep up with current technological developments and innovations.
