Measurement of Information Transfer During Simulated Sequential Complete Shift-to-Shift Intraoperative Handoffs

Abstract

ObjectiveTo determine information transfer during simulated shift-to-shift intraoperative anesthesia handoffs and the benefits of using a handoff tool. Patients and MethodsAnesthesiology residents and faculty participating in simulation-based education in a simulation center on April 6 and 20, 2017, and April 11 and 25, 2019. We used a fixed clinical scenario to compare information transfer in multiple sequential simulated handoff chains conducted from memory or guided by an electronic medical record generated tool. For each handoff, 25 informational elements were assessed on a discrete 0–2 scale generating a possible information retention score of 50. Time to handoff completion and number of clarifications requested by the receiver were also determined. ResultsWe assessed 32 handoff chains with up to 4 handoffs per chain. When both groups were combined, the mean information retention score was 31 of 50 (P<.001) for the first clinician and declined by an average of 4 points per handoff (P<.001). The handoff tool improved information retention by almost 7 points (P=.002), but did not affect the rate of information degradation (P=.38). Handoff time remained constant for the intervention group (P=.67), but declined by 2 minutes/handoff (P<.001) in the control group, which required 7 more clarifications/handoff (P=.003). In the control group, 7 of 16 (44%) handoff chains contained one or more information retention scores below the lowest score of the entire intervention group (P=.007). ConclusionClinical handoffs are accompanied by degradation of information that is only partially reduced by use of a handoff tool, which appears to prevent extremes of information degradation.
