Health Informatics and Digital Health
Subject Summary
The public overview below follows the supplied PhysioVeda Academics subject summary.
Health informatics studies how health data, information systems and digital technologies are designed and used to support safe, effective and coordinated healthcare.
Digital health includes electronic records, telehealth, mobile health, wearables, decision support, digital therapeutics, analytics and artificial intelligence.
The usefulness of a digital system depends on data quality, interoperability, usability, privacy, cybersecurity, governance and appropriate integration into clinical workflow.
Digital tools can improve access, communication and monitoring, but can also introduce alert fatigue, inequity, documentation errors, privacy risks and algorithmic bias.
This summary follows the uploaded PhysioVeda Academics outline from health data and electronic records through interoperability, AI, ethics, governance, evaluation and future directions.
