Improving Handoffs in the Perioperative Environment: A Conceptual Framework of Key Theories, System Factors, Methods, and Core Interventions to Ensure Success.

BACKGROUND: Patient handoffs involve the transition of information and responsibility for care from one health care provider to another. They occur frequently during a patient's perioperative care continuum, potentially introducing communication errors that could result in harmful, even fatal consequences. The perioperative environment poses distinct challenges to team communication and patient safety, which in turn leaves the surgical patient uniquely vulnerable to adverse events. CONCEPTUAL FRAMEWORK: The best way to achieve safe, coordinated handoffs throughout the perioperative continuum has yet to be established. However, a variety of theoretical principles, methods, and interventions have been used successfully in operative and nonoperative contexts among multiple disciplines. Informed by a literature review, the authors describe a conceptual framework for the development, implementation, and sustainment of a multimodal perioperative handoff improvement bundle. The conceptual framework presented here begins with overarching objectives for patient-centered handoff improvement efforts. The article outlines theoretical principles that could be used to guide and inform future multimodal interventions, as well as health care system factors to consider. Further, the authors propose employing data-driven quality improvement and research methodologies to conduct, measure, achieve, and sustain long-term success. Finally, this report describes essential evidence-based interventional components to employ. IMPLICATIONS: Future efforts to improve handoff safety in the perioperative environment will require a comprehensive evidence-based approach. The authors believe the conceptual framework presented here outlines essential components for success. It integrates proven theoretical frameworks, consideration of system factors, data-driven iterative methods, and synergistic patient-centered interventions.

Cervical Spine Movement in a Cadaveric Model of Severe Spinal Instability: A Study Comparing Tracheal Intubation with 4 Different Laryngoscopes.

BACKGROUND: This study compared the Macintosh blade direct laryngoscope, Glidescope, C-Mac d-Blade, and McGrath MAC X-blade video laryngoscopes in 2 cadaveric models with severe cervical spinal instability. We hypothesized that the Glidescope video laryngoscope would allow for intubation with the least amount of cervical spine movement. Our secondary endpoints were glottic visualization and intubation success. METHODS: In total, 2 fresh cadavers underwent maximal surgical destabilization from the craniocervical junction to the cervicothoracic junction by a neurosurgical spine specialist, with subsequent neutral positioning of the heads with surgical head fixation devices. On each cadaver, 8 experienced anesthesiologists performed four intubations with the 4 laryngoscopes in random order. Lateral radiographic measurements determined vertebral displacement during intubation. RESULTS: Cervical spine displacements were not significantly different amongst video laryngoscopes. Cormack-Lehane Grade 1 views were achieved with all attempts with each of the 3 video laryngoscopes; intubation attempts with the Macintosh blade achieved only grade 3 or grade 4 views. Intubation was successful every time with a video laryngoscope but only during 1 of 16 intubation attempts with the Macintosh blade. CONCLUSIONS: In a cadaveric model with maximally destabilized cervical spines, cervical spine movement was observed during attempted laryngoscopy using each of 3 video laryngoscopes, although there was no significant difference between the laryngoscopes. Given cervical spine displacement occurred, these video laryngoscopes do not prevent cervical spine motion during laryngoscopy. However, with improved glottic visualization and intubation success, video laryngoscopes are superior to the Macintosh blade in both cervical spine safety and intubation efficacy in the model studied.
