In an effort to reduce medical errors, doctors are beginning to embrace cognitive aids, such as paper-based checklists. We are in the process of designing an interactive cognitive aid for crisis care teams. This process includes collaboration with anesthesia professors in the school of medicine, specifically the Anesthesia Informatics and Media Lab and observation of medical students practicing in simulated scenarios at the Li Ka Shing Center for Learning and Knowledge. Based on these insights, we are identifying opportunities to employ large-screen displays and coordinated tablets to support team performance. We are prototyping, implementing, and deploying a system design for interactive cognitive aids intended to encourage a shared mental model amongst crisis care staff.
