In this study, the type and frequency of work interruptions for nurses in medical-surgical units in a midwestern tertiary care medical center were identified. In addition, nurses' travel patterns were observed and recorded as they provided care. The intent was to identify methods for reducing interruptions and improving nurses' cognitive work efficiency.
