Measured task load in directed observers versus active participants undergoing high-fidelity simulation education in a critical care setting.

Objectives: The use of directed observers in high-fidelity simulation education is increasingly common. While evidence suggests similar educational outcomes for directed observers compared to active participants in technical skills, it remains uncertain if this benefit also exists for senior clinicians, especially in mental workload. We sought to compare the workload between active participants and directed observers using an objective measure. Methods: We performed a prospective, repeated-measures observational study during the New South Wales Ambulance Aeromedical Operations induction training from 2019 to 2020. Participants included senior critical care doctors, paramedics, and nurses undergoing high-fidelity simulation of prehospital and interhospital aeromedical missions. Task load was measured using the National Aeronautics and Space Administration task load index (NASA-TLX) administered following each simulation debrief. Prehospital and interhospital simulations were compared separately by building a multilevel model for complete case and all study data. Post hoc comparisons of NASA-TLX score for each group were performed using estimated marginal means (EMMs). Results: We enrolled 70 participants, comprising 49 physicians (70%), 19 paramedics (27%), and two flight nurses (3%). From the complete case analysis, statistically significant differences were observed for total NASA-TLX scores between active participants and directed observers in both prehospital (participant EMM 78, observer EMM 65, estimated difference -13, 95% confidence interval [CI] -20 to -7) and interhospital simulations (participant EMM 69, observer EMM 59, estimated difference -10, 95% CI -16 to -3). When all available data were included, the pattern of results did not change. Conclusions: In our sample of senior clinicians, the task load experienced by both active participants and directed observers in high-fidelity simulation education was high for both prehospital and interhospital simulation exercises. The statistically significant differences we report are unlikely to be practically significant. Our results support the use of directed observers when resource limitations do not allow all course attendees to participate in every simulation.

Zero point survey: a multidisciplinary idea to STEP UP resuscitation effectiveness.

The primary survey assessment is a cornerstone of resuscitation processes. The name itself implies that it is the first step in resuscitation. In this article, we argue that in an organized resuscitation the primary survey must be preceded by a series of steps to optimize safety and performance and set the stage for the execution of expert team behavior. Even in the most time critical situations, an effective team will optimize the environment, perform self-assessments of personal readiness and participate in a preemptive team brief. We call these processes the 'zero point survey' as it precedes the primary survey. This paper explains the rationale for the zero point survey and describes a structured approach designed to be suitable for all resuscitation situations.

Major Trauma Outside a Trauma Center: Prehospital, Emergency Department, and Retrieval Considerations.

Care of the critically injured begins well before the patient arrives at a large academic trauma center. It is important to understand the continuum of care from the point of injury in the prehospital environment, through the local hospital and retrieval, until arrival at a trauma center capable of definitive care. This article highlights the important aspects of trauma assessment and management outside of tertiary or quaternary care hospitals. Key elements of each phase of care are reviewed, including management pearls and institutional strategies to facilitate effective and efficient treatment of trauma patients from the point of injury forward.

Bedside review of patient care in an emergency department: The Cow Round.

OBJECTIVE: Clinical handover is a critical point in medical care in the ED, which can contribute to adverse effects for patient care and staff workloads. Over a 4 and a half months in a tertiary referral hospital ED, a centralized whiteboard handover was performed followed by a multidisciplinary review of each patient. This round was referred to as the 'Cow Round'. METHODOLOGY: This observational study used a standardized feedback survey of clinicians leading each Cow Round. The survey asked participants in the round to report issues found, which were not handed over during the centralized whiteboard handover. Data were analysed for the number of issues identified, the type of issue identified, and to determine if there was a relationship between the number of issues reported and patients in the department. RESULTS: 204 surveys met inclusion criteria. Clinical issues not handed over at the standard whiteboard round were found in 64% of Cow Rounds. Of the 2411 patients reviewed on Cow Rounds, 14.1% had at least one clinical issue not handed over during the whiteboard round. A mean of 2.2 issues per round (95% CI 1.9-2.5) were found. Pearson correlation found a relationship between the number of issues identified and the total number of patients in the department (r= 0.246 P= 0.005). CONCLUSION: Review of patients led by a senior member of medical staff, at the patient bedside enables the timely identification and management of issues not communicated during the whiteboard handover process. This review is important when more patients are receiving treatment in the department.

Severity of obstructive apnoea in children with Down syndrome who snore.

Diagnostic overnight polysomnograms of 33 children with Down syndrome who snored were reviewed. Mean age was 4.9 years, none had had adenotonsillectomy, 91% were non-obese (Down syndrome specific body mass index standard deviation score (BMI SDS) <+2.0) and yet 97% demonstrated obstructive sleep apnoea, with an average apnoea hypopnoea index (AHI) of 12.9 episodes per hour (normal <1) and an average oxygen desaturation of 4%. A higher AHI was associated with lower minimum Spo2, higher Tcco2 and higher number of arousals from sleep per hour (p<0.001). Polysomnography should be a routine investigation for children with Down syndrome who snore regardless of body habitus.
