Health Informatics in Contemporary Healthcare Systems: Applications, Benefits, and Emerging Trends

Health informatics enables the methodical facilitation and utilisation of health data across every health system, from the health records of individuals to national health observatories, and therefore has become an integral component of contemporary health systems. In India, the need for health informatics has been established by the various implementations of the Ayushman Bharat Digital Mission, including the Ayushman Bharat Health Account (ABHA), digital health records, eSanjeevani, CoWIN, eHospital, and the Online Registration System and the national disease monitoring and management platforms. This paper outlines the major uses, advantages and emerging perspectives of health informatics in the context of the Indian health system. It is based on a narrative review of Indian-authored publications and official Indian datasets for the period 2019 to 2026. The datasets demonstrate that the ABHA accounts grew from 14.7 crs. in 2021 to over 90 crs. in 2026 with over 100 crs. health records linked to ABHA in May 2026. The eSanjeevani system provided services to 45.42 crs. users, and the National NCD platform enrolled 74.97 crs. beneficiaries by December 2025. These data indicate that health informatics in India has progressed from a pilot phase of digital informatics to the development of large-scale public health systems. Health informatics in India provides several services and benefits, including improved access, continuity of care, and clinical decision making and planning, as well as the monitoring of health services and increased patient engagement. Existing gaps such as the digital divide, data governance, and privacy; along with cyber security, the quality of data, and increased provider burden remain challenges. Health informatics has the potential to strengthen Indian healthcare and digital governance, user training, privacy protection, and equity focused interoperability remain imperative.
