Designing a software interface for healthcare requires thorough domain knowledge, and effective user research and benchmark analysis. This thesis examines the requirements for an improved patient information management system for emergency medicine and describes the iterative process of designing and evaluating the system. I conducted observational study of Emergency Department (ED) physicians’ workflow and information needs, from which I derived a set of functional requirements, created scenarios, performed hierarchical task analysis, and developed a preliminary user model for the patient information management system. Based on these, I developed an interface prototype and evaluated the design with a sample of ED physicians. I review the user testing and design iterations carried out and report on the design improvements made based on the user feedback.
