Crisis checklists in emergency medicine: another step forward for cognitive aids

[Prehospital perimortem cesarean section during cardiopulmonary resuscitation for traumatic cardiac arrest : Case report and lessons learned]

The following case report discusses the resuscitation of a pregnant woman in traumatic cardiac arrest after a fall from a height with consecutive resuscitative hysterotomy for maternal and fetal salvage. The report illustrates all lessons learned from critical appraisal amid new guideline recommendations and gives an overview of the published literature on the matter. Despite extensive resuscitation efforts, ultimately both the mother and the newborn were pronounced life extinct at the scene. Prehospital treatment of (traumatic) cardiac arrest in a pregnant patient as well as performing a perimortem cesarean section remain infrequent but challenging scenarios.

Transitioning Cognitive Aids into Decision Support Platforms: Requirements and Design Guidelines

Digital cognitive aids have the potential to serve as clinical decision support platforms, triggering alerts about process delays and recommending interventions. In this mixed-methods study, we examined how a digital checklist for pediatric trauma resuscitation could trigger decision support alerts and recommendations. We identified two criteria that cognitive aids must satisfy to support these alerts: (1) context information must be entered in a timely, accurate, and standardized manner, and (2) task status must be accurately documented. Using co-design sessions and near-live simulations, we created two checklist features to satisfy these criteria: a form for entering the pre-hospital information and a progress slider for documenting the progression of a multi-step task. We evaluated these two features in the wild, contributing guidelines for designing these features on cognitive aids to support alerts and recommendations in time- and safety-critical scenarios.

Implementing the IMIST-AMBO tool for paramedic to trauma team handovers: a video review analysis

OBJECTIVE

Patient handover between paramedics and the trauma team is vulnerable to communication errors that may adversely affect patient care. This study assesses the feasibility of a handover tool, IMIST-AMBO (acronym of categories), implementation in the trauma bay and evaluates the degree to which it improves handover metrics.

METHODS

This is a prospective observational cohort study conducted at Canada's largest level-one trauma center. Feasibility of the tool implementation and improvement in handover metrics were assessed. Strategies for implementation included distribution of an educational video and posters, and point-of-care reminders in the trauma bay. Two reviewers independently assessed video recordings of handovers to evaluate handover metrics. Findings were compared to data obtained during a knowledge gap analysis conducted prior to the initiation of this study at the same institution.

RESULTS

Over 13 weeks (August to November 2020), 140 videos were recorded, of which 80 used the IMIST-AMBO tool (compliance of 57%). Paramedic adherence to the handover structure occurred in 70.4% of cases, with greater adherence to the IMIST (82.2%) compared to the AMBO (47.1%) section. The mean (± standard deviation) handover duration was shorter (1 min:58 s ± 0:44 s during implementation vs. 2 min:47 s ± 1:14 s pre-implementation, [p < 0.001]). Frequency of parallel conversations and informal handovers improved (61% to 30% and 65% to 13%, [p < 0.001], respectively). Interruptions during the handover decreased from 3.05 (± 1.95) to 1.5 (± 1.7), p < 0.001. The tool was received favorably among study participants.

CONCLUSION

The IMIST-AMBO tool reduced the frequency of interruptions, parallel conversations, and informal handovers during paramedic-trauma team handovers at our institution. The quality and amount of information communicated per handover improved, all with a decrease in handover duration. The IMIST-AMBO tool may be applied to other trauma centers across Canada, or more broadly on an international scale.

Critical event debriefing: a checklist for the aftermath

PURPOSE OF REVIEW

Millions of perioperative crises (e.g. anaphylaxis, cardiac arrest) may occur annually. Critical event debriefing can offer benefits to the individual, team, and system, yet only a fraction of perioperative critical events are debriefed in real-time. This publication aims to review evidence-based best practices for proximal critical event debriefing.

RECENT FINDINGS

Evidence-based key processes to consider for proximal critical event debriefing can be summarized by the WATER mnemonic: Welfare check (assessing team members' emotional and physical wellbeing to continue providing care); Acute/short-term corrections (matters to be addressed before the next case); Team reactions and reflections (summarizing case; listening to team member reactions; plus/delta conversation); Education (lessons learned from the event and debriefing); Resource awareness and longer term needs [follow-up (e.g. safety/quality improvement report), local peer-support and employee assistance resources]. A cognitive aid to accompany this mnemonic is provided with the publication.

SUMMARY

There is growing literature on how to conduct proximal perioperative critical event debriefing. Evidence-based best practices, as well as a cognitive aid to apply them, may help bridge the gap between theory and clinical practice. In this era of increased attention to burnout and wellness, the consideration of interventions to improve the quality and frequency of critical event debriefing is paramount.

The PATH to patient safety

Communication is critical to safe patient care. In this issue of the British Journal of Anaesthesia, Jaulin and colleagues show that use of a Post-Anaesthesia Team Handover (PATH) checklist is associated with fewer hypoxaemia events in the PACU, reduced handover interruptions, and other important metrics related to improved communication. The PATH checklist provides a link within a broader chain of safety checklists and other interventions that comprise a perioperative chain of survival.
