Health information technology (HIT) is “the application of information processing involving both computer hardware and software that deals with the storage, retrieval, sharing, and use of health care information, data, and knowledge for communication and decision making.”[28] Technology is a broad concept that deals with a species’ usage and knowledge of tools and crafts, and how it affects a species’ ability to control and adapt to its environment. However, a strict definition is elusive; “technology” can refer to material objects of use to humanity, such as machines, hardware or utensils, but can also encompass broader themes, including systems, methods of organization, and techniques.[citation needed] For HIT, technology represents computers and communications attributes that can be networked to build systems for moving health information. Informatics is yet another integral aspect of HIT.

Health information technology can be divided into further components like Electronic Health Record (EHR), Electronic Medical Record (EMR), Personal Health Record (PHR), Practice Management System (PMS), Health Information Exchange (HIE) and many more. There are multiple purposes for the use of HIT within the health care industry. Further, the use of HIT is expected to improve the quality of health care, reduce medical errors, improve the health care service efficiency and reduce health care costs.
