This document discusses two studies on improving shift handovers between operators. The first study evaluated a structured integrated checklist logbook versus a less structured logbook for handovers between operators at an oil refinery. It found the integrated checklist logbook improved the quality of logbook documentation, second shift operator recall of information, and handover times. The second study tested implementing a standardized handover tool and process for nurses and found it increased nurses' confidence and preparedness, decreased anxiety, and reduced time spent searching medical records, with potential for increased patient safety.
