Health information technology is “the application of knowledge methodically, involving every constituent and code that deals with the storage, retrieval, sharing, and use of healthcare information data for communication and decision making”. It is nothing but a broad conception of using technology as a tool to manage and adapt to its settings. However, a strict definition is elusive; "technology" can raise material objects of use to humanity, like machines, hardware or utensils, but can also embody broader themes, further as systems, methods of organization, and techniques. For Healthcare information technology, technology represents computers and communications attributes which will be networked to form systems for circulating health information. Study is an extra integral facet of Healthcare information technology. Study refers to the science of knowledge, the application of knowledge and engineering of knowledge systems. Study underlies the academic investigation and professional application of computing and engineering to health education and medical analysis. Health study refers to the intersection of knowledge in the field of science, engineering, and healthcare. Health study describes the use and sharing of knowledge at intervals to benefit the healthcare industry with contributions from engineering, arithmetic, and science. It deals with the resources, devices, and methods required for optimizing the acquisition, storage, retrieval, and use of knowledge in health and biomedicine. Health study tools embrace not only computers but also the clinical pointers, formal medical terminologies, and information and communication systems. Medical study, nursing study, public health study, and pharmacy study area unit sub disciplines that inform health study from entirely completely different disciplinary views. Health information technology (HIT) is usually viewed as a result of the foremost promising tool for rising the final quality, safety and efficiency of the health delivery system.
