Blood product ordering in pediatrics is a complex, high-risk task requiring providers to integrate patient, workflow, and technical factors to avoid severe medical errors. We used user-centered design principles including stakeholder review and formative usability testing to standardize blood product ordering across a large pediatric healthcare system. In summative usability testing, we demonstrated a 75% reduction in severe ordering errors with no change in ordering efficiency and a trend towards improved provider understanding of indications for blood processing requests.
Learning Objective: 1) Identify the differential influence of stakeholder review, formative usability testing, and summative usability testing on order set design.
2) Describe methods to evaluate and maximize the educational impact of clinical decision support.
3) Understand the costs and benefits of integrating usability testing into design of high-risk clinical decision support.
