Abstract
The design of Electronic Medical Record (EMR) systems and other clinical information systems challenges traditional HCI design in the following two ways: (a) system interactions involve multiple clinician/non-clinician teams, various interactive medical devices and medical artifacts in highly mobilized contexts, and (b) it is extremely difficult for designers to understand the highly knowledge-intensive clinical medicine field and design a system to fit into the hospital environment. Past literature suggests that context of system use could potentially solve these EMR design challenges. To enhance system design quality and bridge designers' expertise and end-users' domain understanding, we developed an operational method called Context-Centered Framework and carried out an empirical study to test the effectiveness of it. The empirical study examined the impact of the framework on a mobilized nursing task using scenario-based design and claims analysis approaches. The results indicated that designers improved their understanding towards the clinicians' working environment and incorporated more usability concerns in their design product through the use of the Context-Centered Framework. This suggests that focusing on the context of system use could improve the quality of design for the systems situated in the highly complex, mobile and ubiquitous environment and could benefit clinicians' practice.
