Navigating the challenges of performing anesthesia handoffs and conducting anesthesia handoff research

A Quality Improvement Initiative to Reduce Adverse Effects of Transitions of Anesthesia Care on Postoperative Outcomes: A Retrospective Cohort Study

BACKGROUND

An intraoperative transfer of care from one anesthesia provider to another, or handover, may result in information loss and contribute to adverse patient outcomes. In 2019 the authors undertook a quality improvement effort to increase the use of a structured intraoperative handover tool incorporated in the electronic medical record. The authors hypothesized that intraoperative handovers of anesthesia care would be associated with adverse patient outcomes, and that increased use of a structured tool would attenuate this effect.

METHODS

This study included adult patients undergoing noncardiac surgery of at least 1 h duration performed during the period 2016 to 2021. Cases with a handover were identified if either there was a change of attending anesthesiologist or change of nurse anesthetist or resident for more than 35 min. The primary outcome was the occurrence of a composite of postoperative mortality and major postoperative morbidity. The effect of the intervention was analyzed by examining the quarterly change in odds ratio for the primary outcome for cases with and without a handover.

RESULTS

A total of 121,077 cases, 40.4% of which had a handover, were included. After weighting, the composite outcome was statistically associated with handovers (3,517 of 48,986 [7.2%] in handover cases vs. 4,470 of 72,091 [6.2%] in nonhandover cases; odds ratio, 1.08; 95% CI, 1.04 to 1.12). Time series analysis showed a marked increase in usage of the structured tool after the initial intervention. The odds ratio for the composite outcome showed a significant decrease over time after the initial intervention (t = -3.97; P < 0.001), with the slope of the odds ratio versus time curve decreasing from 0.002 (95% CI, 0.001 to 0.004; P = 0.018) to -0.011 (95% CI, -0.01 to -0.018; P < 0.001).

CONCLUSIONS

Intraoperative handovers are significantly associated with adverse outcomes even after controlling for multiple confounding variables. Use of a structured handover tool during anesthesia care may attenuate the adverse effect.

Anesthesiology Patient Handoff Education Interventions: A Systematic Review

BACKGROUND

Anesthesiology provider handoffs are complex, occur frequently, and have been associated with adverse patient outcomes. The authors sought to determine the degree to which anesthesiology handoff studies with educational interventions incorporated tenets of educational best practices.

METHODS

The research team conducted a systematic review of the peer-reviewed literature focused on handoff studies with education interventions that included anesthesiology providers. Searches were conducted using PubMed, Embase, Scopus, Cochrane, and ERIC (2010-September 2021). Each phase of the article review process included at least two trained independent reviewers. In addition, pairs of trained reviewers abstracted study characteristics RESULTS: Twenty-six articles met inclusion criteria. Two thirds (18/26; 69.2%) were published after 2017, and almost three fourths (19/26; 73.1%) included learners. Education intervention descriptions varied, with only 15.4% (4/26) briefly mentioning education theory, 7.7% (2/26) with clear education objectives, and 7.7% (2/26) assessing curriculum via participant satisfaction. Most (22/26; 84.6%) assessed Kirkpatrick's level 3 (handoff behavior change), and 26.9% (7/26) assessed level 4b (patient outcomes). Medical education quality scores were low (range 6-24, mean 11.3; max 32), with more than half (15/26; 57.7%) receiving scores ≤ 10.

CONCLUSION

Educational interventions demonstrate marked heterogeneity in the use of educational theoretical concepts and established curriculum development best practices. Future studies should report on important aspects of educational interventions, which would allow for comparison across studies, yield the essential data needed to identify handoff education best practices, and improve patient safety.
