Impact of clinician training background and stroke location on bedside diagnostic test accuracy in the acute vestibular syndrome - a meta-analysis.
Researchers conducted a systematic review to assess the accuracy of bedside diagnosis of acute dizziness/vertigo to differentiate peripheral vestibular from central neurologic causes. Their review indicated that the Head Impulse, Nystagmus, Test of Skew (HINTS) examination by trained clinicians can differentiate peripheral from central causes and show higher diagnostic accuracy for stroke in the first 24-48 hours than MRI diffusion-weighted imaging. They concluded that these techniques should be disseminated to clinicians evaluating dizziness/vertigo.

Current use, training, and barriers in point-of-care ultrasound in hospital medicine: a national survey of VA hospitals.
This study aimed to characterize current point-of-care ultrasound (POCUS) use, training needs, and barriers to use among hospital medicine groups (HMGs). This prospective observation study looked at all Veterans Affairs (VA) medical centers from August 2019 to March 2020 using a web-based survey sent to all chiefs of HMGs. There was a 90% response rate from 117 HMGs. Procedural POCUS use decreased by 19% from 2015 to 2020 but increased for diagnostic use for cardiac (8%), pulmonary (7%), and abdominal (8%) applications. The most common barrier to POCUS use was lack of training (89%), with only 34% of HMGs having access to POCUS training. Access to ultrasound equipment was the least common barrier at 57%, however with the proportion of HMGs with ≥1 ultrasound machine increasing from 29% to 71% from 2015 to 2020. In 2020 an average of 3.6 ultrasound devices per HMG was available, and 45% were handheld devices.

Formative assessment of performance in diagnostic ultrasound using simulation and quantitative and objective metrics.
The authors of this article describe how they developed simulator-based tools for assessing provider competence in transthoracic echocardiography (TTE) and vascular duplex scanning. Psychomotor skill in TTE image acquisition was calculated using the deviation angle of an acquired image from the anatomically correct view, and this skill metric applied for formative assessment to evaluate curricula and provide feedback to learners. Psychomotor skill in vascular ultrasound was measured in terms of dexterity and image plane location. The skill metric in the TTE simulator enabled immediate feedback, as well as formative assessment of curriculum efficacy and a comparison of curriculum outcomes. The vascular duplex ultrasound simulator also provided feedback. The authors conclude that skill in acquiring diagnostic ultrasound images of organs and vessels can be measured using simulation in an objective, quantitative, and standardized manner. Simulator-based metrics might also be applied to summative assessment.

Use of EHR-based simulation to diagnose aetiology of information gathering issues in struggling learners: a proof of concept study.
The researchers previously documented that high-fidelity EHR-based simulation improves EHR usability and, when combined with eye and screen tracking, generates important measures of usability. They hypothesised that the same simulation exercise could help distinguish whether learners had difficulty in knowledge, information gathering or information processing. In this paper, they report the results of the first three struggling learners who participated in this exercise.

A validation argument for a simulation-based training course centered on assessment, recognition, and early management of pediatric sepsis.
The aim of this study was to create a validity argument for the use of a simulation-based training course centered on assessment, recognition, and early management of sepsis in a laboratory-based setting. The authors concluded that, although incomplete, evidence from initial testing suggests that the simulations of pediatric sepsis were sufficiently valid to justify their use in training novice pediatric physicians in the assessment, recognition, and management of pediatric sepsis.

Simulation and the diagnostic process: a pilot study of trauma and rapid response teams.
Simulation can be used to recreate conditions that engage teams in the diagnostic process. In contrast to most instruction about diagnostic error, teams learn through realistic experiences and receive timely feedback about their decision-making skills. The purpose of this study was to assess how trauma teams (TrT) and pediatric rapid response teams (RRT) managed scenarios that included a diagnostic error.

Skill assessment in the interpretation of 3D fracture patterns from radiographs.
The researchers determined if 3D radiographic image interpretation can be reliably assessed, and whether this assessment varies by level of training. They concluded that the interpretation of radiographs to discern 3D information is a promising and a relatively unexplored area for surgical skill education and assessment.

Paramedic perspectives on barriers to prehospital acute stroke recognition.
The researchers aimed to understand systematically the challenges and barriers faced by paramedics in recognizing stroke presentations in the field. They concluded that while challenges to stroke recognition in the field were slightly different for rural and urban emergency medical service providers, participants concurred that timely, systematic feedback on individual patients and case-based training would strengthen early stroke recognition skills.
