A descriptive, correlational study of medication administration timing error prevalence in acute care, underreporting among acute care nurses, and the correlation to patient safety culture
Background. Medication administration timing errors are associated with patient harm. Complicated by underreporting, accurate rates have been elusive. Correlation with patient safety culture is unknown. Purpose. Guided by high reliability organization theory, this study aimed to describe individual …

Recovery-driven design: Exploiting error resilience in design of energy-efficient processors
… module for correct operation and prohibit timing violations during nominal operation. We propose recovery-driven design, a design approach that optimizes a processor module for a target timing error rate instead of correct operation. The target error rate is chosen based on how many errors …
