Questions I want to answer

• How can we improve the the role and integration of computer based ordering in healthcare?
• Can we improve the design and interface of computer practioner order entry (CPOE) systems by considering all facets of technical, medical, organizational, environmental and individual worker behaviors?

Current Research Projects

We are studying the effectiveness of drug alerting in the CPOE system at Puget Sound VA. When clinicians enter orders, a rule-based program checks the order for any potential problems with patient allergies or interactions with current medications. Our research has shown that there is a very high rate of clinicians continuing with orders despite these warnings often because the alerts are not relevant or are based on incomplete data. We are interested in using this work as a springboard to study how the ordering and alert system can be redesigned by using a Cognitive Work Analysis (CWA) framework to examine the environment.
