In order to comply with changing regulations and to improve support for office staff, clinicians, and patients, healthcare organizations worldwide are currently undertaking massive transformations and additions to their IT infrastructure. History suggests that the success of the healthcare applications that emerge from this process will depend to a large degree on the ability of people to use them effectively and efficiently. Human-computer interaction (HCI) research can provide valuable guidance to improve the usability of healthcare IT. Potential exists for HCI researchers to apply existing knowledge to improving healthcare IT as well as to formulate new theories and practices specific to the healthcare context. Our goal in initiating this minitrack is to provide a focused outlet at HICSS for HCI researchers in healthcare domains to share and discuss the results of their work.
