Stanford University
Medical Checklists, Crisis Attention and Interactive Cognitive Aids
April 12, 2013
Medical checklists improve performance in the volatile and complex domain
of emergency medicine. Such cognitive aids are only now being adopted, in
paper form, in hospitals and clinics across the world. I believe that
software and interactive technologies offer the opportunity to improve and
distribute these aids widely, with the hope of reducing medical errors and
saving lives.
However, these new, 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 talk describes how we have begun to address these
challenges with design prototyping, engineering, and scientific evaluation.
In this talk, I describe an interactive software system, iCogAid, that
helps medical teams follow Advanced Cardiac Life Support (ACLS) protocol,
as they respond to emergency codes such as heart attacks in ORs 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 present data on the
efficacy of dynamic and interactive aids for supporting doctors as they
respond to simulated ACLS scenarios, under time- and attention-
constraints, suggesting that our software-based iCogAid system effectively
supports doctors' crisis attention and performance.

Leslie Wu is a Ph.D. candidate in Computer Science at Stanford University,
advised by Stuart Card and Pat Hanrahan. Her research applies modern,
mobile software technologies to addressing issues in public health and
medicine. Her thesis work focuses on the development and evaluation of
iCogAid: effective interfaces for crisis medical checklists and interactive
cognitive aids. iCogAid is a joint collaboration between Dr. Larry Chu and
Dr. Kyle Harrison at the Stanford School of Medicine (Anesthesia
Informatics & Media Lab) and the Stanford Computer Science Human-Computer
Interaction group, including Dr. Scott Klemmer, Ph.D. candidate Jesse
Cirimele, and Dr. Stuart Card. You can follow Leslie on Twitter @1wu, or
