Health informatics in current healthcare system: A review

Abstract

Health informatics integrates information science, computing and digital technologies to support clinical care, healthcare administration and public health. Therefore, it is of interest to review the applications, benefits and challenges of health informatics in contemporary healthcare systems. This review focuses on major health informatics applications such as electronic health records, clinical decision support systems, telemedicine and artificial intelligence. Thus, we show that these technologies contribute to improved quality of care, enhanced patient safety and increased healthcare efficiency through better data management and decision support. Additionally, health informatics supports population health monitoring and healthcare planning. However, significant challenges persist, including lack of interoperability, increased clinician workload, cybersecurity risks, data privacy concerns and ethical governance issues. Addressing these barriers is essential to ensure the secure, equitable and sustainable adoption of health informatics within modern healthcare systems.
