Health informatics is the field that combines healthcare, information technology, and data management to improve patient care and health outcomes. It involves the use of electronic health records (EHRs), data analysis, and communication tools to streamline processes in hospitals and clinics, making it easier for healthcare providers to access and share patient information. By utilizing health informatics, healthcare professionals can make informed decisions based on accurate data. This discipline also supports research and public health initiatives by analyzing trends and patterns in health data, ultimately leading to better healthcare policies and practices.
