The denial of decision support and research tools using real-time communication between medical centres is an ongoing problem in Ontario. Through fieldwork, a relationship was established with a neuroradiologist at a local area research hospital, and permission was obtained to create a website based on study data of patients suffering cerebral aneurysms as a step toward resolving this problem. One hundred case files from 2012-2013 were assembled, anonymized and exported from the hospital’s patient records. Post-processing of patient’s images was performed to secure a level of interactivity commensurate with users’ experience through their workplace software. Paper prototypes of interface designs were created for both desktop and mobile platforms. These prototypes were presented to ‘lay’ users and then to representative end users— neuroradiologists at two local area research hospitals. Interaction with the prototype and the ensuing discussions led to the creation of a second prototype, which in turn was presented at each hospital. Observations and findings from these sessions provided a set of design considerations. These considerations led to the formation of a design model which can serve as a basis for ensuring user contribution and reward for participating in an online medical research registry.
