Health Informatics (HI) basically defines how health information is technically captured, transmitted and utilized. New technology can be an integral part of medicine, and health informatics is no exception. Healthcare informatics is the science that underlies the fusion of health care, information technology, and business administration, and guides into all aspects of the patient health experience, including clinical care, nursing, pharmacy and public health. Not only does healthcare informatics focus on the implementation and optimization of the information systems that support clinical practice, it creates the infrastructure that connects and enables the flow of critical information to and from each of the stakeholders in a patient's care.
