Health Informatics is the intersection of information technology, information science with public health and health care. It deals with resources, devices, methods and institutions required to optimize the acquisition, storage, retrieval, and use of information in public health and health care. While some scholars date the use of health informatics to the 1800s, the first evidence of computer-generated healthcare data appears in the United States in the mid-1950s.The most important way in which informatics is changing health care is in improved outcomes. Electronic medical records result in higher quality care and safer care as coordinated teams provide better diagnoses and decrease the chance for errors.
