Handoff mnemonics used in perioperative handoff intervention studies: a systematic review.

Mnemonics are a commonly used memory aid to ensure standardized, structured handoffs between providers. This review summarizes mnemonics used in perioperative handoffs. Situation, Background, Assessment, Recommendation (SBAR) and SBAR variations were the most common, followed by I-PASS (Illness severity, Patient summary, Actions list, Situation awareness, Synthesis), and I-PASS variants. Most studies reported only on process outcomes; only four measured patient outcomes.
