The study describes interruptions, distractions, and cognitive load experienced by registered nurses during medication administration and explores their impact on procedure failures and medication administration errors. The focus of this study was unique as it investigated how known individual and environmental factors interacted and culminated in errors. © 2017 Wolters Kluwer Health, Inc. All rights reserved.
