Human Factors Engineering in HI: So What? Who Cares? and What's in It for You?

Human factors engineering is a discipline that deals with computer and human systems and processes and provides a methodology for designing and evaluating systems as they interact with human beings. This review article reviews important current and past efforts in human factors engineering in health informatics in the context of the current trends in health informatics.

The methodology of human factors engineering and usability testing in particular were reviewed in this article.

This methodology arises from the field of human factors engineering, which uses principles from cognitive science and applies them to implementations such as a computer-human interface and user-centered design.

Patient safety and best practice of medicine requires a partnership between patients, clinicians and computer systems that serve to improve the quality and safety of patient care. People approach work and problems with their own knowledge base and set of past experiences and their ability to use systems properly and with low error rates are directly related to the usability as well as the utility of computer systems. Unusable systems have been responsible for medical error and patient harm and have even led to the death of patients and increased mortality rates. Electronic Health Record and Computerized Physician Order Entry systems like any medical device should come with a known safety profile that minimizes medical error and harm. This review article reviews important current and past efforts in human factors engineering in health informatics in the context of the current trends in health informatics.
