One key ingredient for a successful POE implementation is to involve physicians in all aspects of POE implementation, from design, to implementation, to evaluation. Such involvement is important, because physicians are the primary POE users and the benefits of POE can only be achieved if the system meets the physicians' needs. Studies show that systems that do not meet physicians' needs often fail. Despite the importance of meeting these needs, none of the studies report using standard, formal methods for assessing physician needs and how best to design technology to meet those needs. Such methods have been studied extensively in the field of Human-Computer Interaction (HCI). To increase the chance of a successful POE implementation, the paper proposes that techniques from the field of HCI should be used to enhance the interaction between technology and the physicians. Therefore, we should utilize these techniques in expanding our knowledge of the user-POE interaction. To demonstrate such methods, the paper reviews the use of various HCI methods in health care, and their potential for increasing the chances of POE success by assessing physician needs and developing a POE system that meets those needs.
