BackgroundPerioperative handoffs are known to present unique challenges to safe and effective patient care. Numerous national accrediting bodies have called for standardized, structured handoff processes. Handoff mnemonics provide a memory aid and standardized structure, as well as promote a shared mental model. We set out to identify perioperative handoff intervention studies that included a handoff mnemonic; critically assess process and patient outcome improvements that support specific mnemonics; and propose future recommendations.MethodsWe conducted a systematic review of the English language perioperative handoff intervention literature designed to identify handoff mnemonic interventions. A comprehensive protocol was developed and registered (CRD42022363615). Searches were conducted using PubMed, Scopus, ERIC (EBSCO), Education Full Text (EBSCO), EMBASE (Elsevier), and Cochrane (January 1, 2010 to May 31, 2022). Pairs of trained reviewers were involved in all phases of the search and extraction process.ResultsThirty-seven articles with 23 unique mnemonics met the inclusion criteria. Most articles were published after 2015 (29/37; 78%). Situation, Background, Assessment, Recommendation (SBAR), and SBAR variants were used in over half of all studies (22/37; 59%), with 45% (10/22) reporting at least 1 statistically significant process improvement. Seventy percent of handoff mnemonics (26/37) were expanded into lists or checklists. Fifty-seven percent of studies (21/37) reported using an interdisciplinary/interprofessional team to develop the intervention. In 49% of all studies (18/37) at least 1 measurement tool was either previously published or the authors conducting some form of measurement tool validation. Forty-one percent of process measurement tools (11/27) had some form of validation. Although most studies used training/education as an implementation strategy (36/37; 97%), descriptions tended to be brief with few details and no study used interprofessional education. Twenty-seven percent of the identified studies (10/37) measured perception alone and 11% (4/37) measured patient outcomes.ConclusionsWhile the evidence supporting one handoff mnemonic over others is weak, SBAR/SBAR variants have been studied more often in the perioperative environment demonstrating some process improvements. A key finding is that 70% of included studies converted their handoff mnemonic to a list or checklist. Finally, given the essential nature of effective handoffs to perioperative patient safety, it is crucial that handoff interventions are well developed, implemented, and evaluated. We propose 8 recommendations for future perioperative handoff mnemonic clinical interventions and research.Copyright © 2024 The Author(s).
