What is it about?
An existing usability problem with medical alarms negatively affects clinicians' ability to gain awareness of important actionable changes in patients' needs for healthcare. A context-enabled wearable attention aid prototype is empirically evaluated with teams of registered nurse (RN) volunteers in a 20-bed hospital acute care patient simulation facility.

Why is it important?
Results of a within-subjects, simulation-based, experiment show that RNs respond to important actionable alarms/alerts 3X faster on average when using the wearable attention-aid. This large improvement in response time can enable clinical intervention in time to prevent adverse events.
Perspectives
Our empirical study shows the feasibility of solving a critical usability problem with medical alarms/alerts. Clinical simulation enables sufficient experimental controls to achieve both high internal validity and high external validity. These results show a new approach for overcoming the current healthcare crisis with adverse events.
