For consumer health informatics (CHI) interventions to successfully aid laypeople, the interventions must fit and support their health work. This paper outlines a scenario-based human factors assessment of a disease management CHI intervention. Two student users undertook a patient use case and another user followed a nurse use case. Each user completed pre-specified tasks over a ten-day trial, recorded challenges encountered while utilizing the intervention, and logged daily time spent on each task. Results show the scenario-based user testing approach helps effectively and systematically assess potential physical, cognitive, and macroergonomic challenges for end-users, rate the severity of the challenges, and identify mediation strategies for each challenge. In particular, scenario-based user testing aids in identifying challenges that would be difficult, if not impossible, to detect in a laboratory-based usability study. With this information, CHI interventions can be re-designed and/or supplemented, making the intervention more closely fit end-users' work.
