Answer:

Medical information technology is often thought of in the modern context of computers, but the careful collection and analysis of information related to observation of patient condition, effectiveness of different treatments, and design of new treatments dates back to the time of Hippocrates (ca. 460 BC – ca. 370 Be) (Washburn & Hornberger, 2008). Hippocrates took meticulous notes that enabled him to make numerous breakthroughs both in the understanding of the workings of the human body and in the ethics and approach to thinking that are essential to modern medical practice and investigation (Olguin, Gloor & Pentland, 2009). Comparatively little innovation took place in furthering, the practice of medicine from the time of Hippocrates until the early 20th century, with developments such as the smallpox vaccine in 1901.
