Innovations in Public Health: The Role of Technology in Improving Access to Healthcare Services

Technological developments have had a significant impact on the transformation of public health services, especially in improving the accessibility of services in areas that are difficult to reach or have limited infrastructure. Innovations such as telemedicine, blockchain, Internet of Things (IoT), and artificial intelligence (AI) have become solutions to overcome geographical, logistical, and resource barriers for healthcare workers. This research aims to explore how technology can improve access to healthcare and identify innovative technologies that have proven effective in expanding the scope of healthcare globally. This research uses a qualitative method based on literature studies, which includes analysis of scientific articles, institutional reports, and official documents published in the last five years (2018–2023). The data collection technique is carried out through systematic searches on scientific databases such as PubMed and Scopus with specific keywords related to health technology. The results show that technologies such as telemedicine have enabled remote medical consultations that speed up the diagnosis and treatment of patients in remote areas. Meanwhile, blockchain improves the interoperability of medical data, and IoT supports real-time health monitoring through wearable devices. The study also found that the implementation of technology requires policy support, infrastructure investment, and training of healthcare workers to ensure widespread and sustainable adoption. With the right strategy, technology has the potential to create a more inclusive, efficient, and resilient health system.
