Dynamic procedure aids support crisis attention
Abstract/Contents
- Abstract
- Medical checklists can improve performance in the volatile, uncertain, complex, and ambiguous domain of emergency medicine. Such procedure aids are only now being adopted, in paper form, in hospitals and clinics across the world. Software-based aids offer an opportunity to improve upon the effectiveness of static, paper aids, since digital aids afford interactivity, high-speed distribution, and dynamic content. However, software-based medical checklists must work seamlessly in uncertain, time-pressured scenarios. In these team-based, multitasking environments, a users attention is limited. These attentional aspects of crisis computing--supporting highly trained teams as they respond to real-life emergencies--have been underexplored in the user interface community. This dissertation describes research that begins to address these challenges with design prototyping, constraint analysis, engineering, simulation, and evaluation. This dissertation describes an interactive software system, dpAid, that supports medical teams in action by displaying relevant checklist aids. dpAid helps doctors follow Advanced Cardiac Life Support (ACLS) protocol, as they respond to emergency codes such as heart attacks in operating rooms or hospital wings. The design of this system was based on 18 months spent observing Stanford medical residents responding to simulated crises in high-fidelity medical simulators with realistic patient mannequins. I develop and analyze users' time- and attention- constraints, leading to four design concepts: shared displays for ready access, step-at-a-glance for rapid assimilation, resources-at-a-glance for professional acceptance, and attention aids for limited attention. I present a simulation/evaluation approach, narrative simulation that comparatively assesses expert performance through a score-and-correct approach. I present data on the effectiveness of dynamic and interactive aids for supporting doctors as they respond to simulated ACLS scenarios, suggesting that the software-based dpAid system effectively supports crisis attention and performance. More broadly these experimental results suggest that the Dynamic Procedure Aid (dpAid) approach can improve user performance in complex, high-risk domains.
