Why health informatics is the basis of all healthcare: "We tend to think of health information technology (HIT) primarily in terms of EMRs, PACS, and billing and coding software. These kinds of HIT are a necessary focus of interest, given that providers are so far behind in using them. But there is more to HIT than EMRs and PACS.
According to the Office of the National Coordinator for Health Information Technology (ONC), health information technology 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.”
This means that everything from a gene bank to an implanted biomonitoring sensor is an HIT. "
