ABSTRACT
INTRODUCTION: With increased incorporation of simulation-based methodologies into quality improvement activities, standards for reporting on simulation-specific elements in healthcare improvement research are needed. METHODS: We followed established consensus process methodology to iteratively create simulation-based extensions for SQUIRE 2.0 reporting guidelines. Initial steps involved forming a steering committee, defining the scope, and conducting premeeting activities with an expert panel of simulation and quality improvement researchers. Recommendations from the expert panel were brought to a consensus meeting where existing guidelines were reviewed and recommendations made. Steering Committee members reviewed all recommendations, reconciled differences, and made final recommendations, which were piloted by experienced simulation and quality improvement researchers. RESULTS: Fifteen Steering Committee members, 59 experts in simulation and quality improvement research, and 86 consensus meeting attendees reviewed SQUIRE 2.0 reporting guidelines and ultimately recommended simulation-based reporting guidelines for 22 of the 41 (54%) SQUIRE 2.0 guidelines. Those items for which simulation-based extensions were identified were: Notes to Authors, 1 (Title), 2a (Abstract), 2b (Abstract), 4 (Introduction: Available knowledge), 5 (Introduction: Rationale), 7 and 8a & b (Methods: Context and intervention), 9a (Methods - Study of the intervention), 9b (Methods - Study of the intervention), 10a (Methods - Measures), 10b (Methods-Measures), 10c (Methods-Measures), 11b (Methods- Analysis), 12 (Methods - Ethical considerations), 13a (Results), 13e (Results), 14b (Discussion - Summary), 15a-e (Discussion - Interpretation), 16a (Discussion - Limitations), 16b (Discussion - Limitations), 17c (Discussion - Conclusions), and 17d (Discussion - Conclusions). CONCLUSIONS: We created simulation-based extensions to SQUIRE 2.0 reporting guidelines to improve the quality and standardization of reporting on simulation-specific elements of healthcare improvement research.
ABSTRACT
Children with heart disease are at increased risk of unstable dysrhythmias and in-hospital cardiac arrest (IHCA). Clinician adherence to lifesaving processes of care is an important contributor to improving patient outcomes. This study evaluated whether critical event checklists improve adherence to lifesaving processes during simulated acute events secondary to unstable dysrhythmias. A randomized controlled trial was conducted in a cardiac ward in a tertiary care, academic children's hospital. Unannounced simulated emergencies involving dysrhythmias in pediatric patients with underlying cardiac disease were conducted weekly. Responders were pediatric and anesthesiology residents, respiratory therapists, and bedside registered nurses. Six teams were randomized into two groups-three received checklists (intervention) and three did not (control). Each team participated in four simulated scenarios over a 4-week pediatric cardiology rotation. Participants received a brief slideshow presentation, which included a checklist orientation, at the start of their rotation. Simulations were video and audio recorded and those with three or more participants were included for analysis. The primary outcome was team adherence to lifesaving processes, expressed as the percentage of completed critical management steps. Secondary outcomes included participant perceptions of the checklist usefulness in identifying and managing dysrhythmias. We used generalized estimating equations (GEE) models, which accounted for clustering within groups, to evaluate the effects of the intervention. A total of 24 simulations were conducted; one of the 24 simulations was excluded due to an insufficient number of participants. In our GEE analysis, 81.21% (78.96%, 83.47%) of critical steps were completed with checklists available versus 68.06% (59.38%, 76.74%) without checklists (p = 0.004). Ninety-three percent of study participants reported that they would use the checklists during an unstable dysrhythmia of a child with underlying cardiac disease. Checklists were associated with improved adherence to lifesaving processes during simulated resuscitations for unstable pediatric dysrhythmias. These findings support the use of scenario specific checklists for the management of unstable dysrhythmias in simulations involving pediatric patients with underlying cardiac disease. Future studies should investigate whether checklists are as effective in actual pediatric in-hospital emergencies.
ABSTRACT
OBJECTIVES: Asthma is a leading cause of pediatric emergency department visits, yet few tools exist to objectively measure asthma severity. Diaphragmatic ultrasound (DUS) is a novel method of assessing respiratory distress; however, data are lacking for children.Our primary aim was to determine if diaphragmatic excursion (DE), diaphragmatic thickening (DT), or diaphragmatic thickening fraction (TF) correlated with asthma severity as determined by the Pediatric Respiratory Assessment Measure (PRAM) score. Secondarily, we examined if these parameters correlated with need for respiratory support and evaluated interrater reliability. METHODS: We conducted a prospective study of children 5-18 years presenting to a pediatric emergency department with an asthma exacerbation. Diaphragmatic ultrasound was performed by a trained pediatric emergency medicine sonologist in subcostal (DE) and midaxillary (DT). Thickening fraction was calculated from DT values as previously described in literature. To evaluate interrater reliability, a subset of subjects had DUS performed by a second sonologist. RESULTS: We enrolled 47 subjects for a total of 51 encounters. The mean age was 9.1 ± 3.7 years. Twenty-five (49%) had mild, 24 (47%) had moderate, and 2 (4%) had severe asthma. There was a significant difference in midaxillary DT and TF between children with mild and moderate asthma ( P = 0.02; mean difference, 0.2 mm; 95% confidence interval [CI], 0.03-0.4 and P = 0.02; mean difference, 0.11 mm; 95% CI, 0.02-0.2, respectively). No difference was found in subcostal DE ( P = 0.43; mean difference, 1.4 mm; 95% CI, -2.1 to 4.8). No association was found between use of positive pressure and DUS parameters. Fourteen encounters had 2 sonologists perform DUS, with strong interrater reliability found for midaxillary DT (Pearson correlation, 0.56) and poor association for subcostal DE (Pearson correlation, 0.18). CONCLUSIONS: In this pilot study, we conclude that DUS may be helpful in assessing severity of asthma. The midaxillary view assessment for DT and TF had the best correlation with asthma severity and the best interrater reliability. Future studies may benefit from focusing on the midaxillary view for DT and TF.

OBJECTIVE: To determine if caregivers would be able to successfully perform in home lung ultrasounds on their children without direct supervision after undergoing a basic tutorial that would allow for expert interpretation. METHODS: A prospective exploratory single-center cohort study was conducted on patients (0-18 years) presenting to a pediatric emergency department with a respiratory complaint or COVID-related illness. Caregivers underwent a brief hands-on session and were instructed to scan the lungs daily for 7 days. Images were assessed using a modified POCUS IQ score. Descriptive statistics were used to describe the data and bivariate analysis was used to compare groups. RESULTS: Eighteen patients were enrolled; the average age of the parent scanner was 31.9 years and 78% were female. Of all participants, 77.8% scanned on day one. Parents were able to successfully perform some part of the daily scan session for an average of 3.8 out of 7 days. The average POCUS IQ score overall was 6.7 (out of 12). CONCLUSION: Our study demonstrates the feasibility and acceptability of caregiver ability to obtain adequate lung ultrasound images, at home under no guidance, using the Butterfly iQ probe. Further studies are needed to investigate the accessibility of ultra-portable ultrasound and the ability to integrate with the at-home hospital model, specifically in the pediatric population.

SUMMARY STATEMENT: Simulation-based health professions educators can advance diversity, equity, and inclusion by cultivating structural competency, which is the trained ability to discern inequity not only at an individual level, but also at organizational, community, and societal levels. This commentary introduces Metzl and Hansen's Five-Step Model for structural competency and discusses its unique applicability to the metacognitive underpinnings of simulation-based health professions education. We offer a pragmatic guide for simulation-based health professions educators to collaboratively design learning objectives, simulation cases, character sketches, and debriefs in which structural competency is a simulation performance domain, alongside patient management, resource usage, leadership, situational awareness, teamwork, and/or communication. Our overall goal is to promote a paradigm shift in which educators are empowered to partner with patients, colleagues, and communities to recognize, learn about, and challenge the factors driving health inequities; a skill that may be applied to a broad range of health professions education within and outside of simulation.

INTRODUCTION: Resuscitation events in pediatric critical and emergency care are high risk, and strong leadership is an important component of an effective response. The Concise Assessment of Leadership Management (CALM) tool, designed to assess the strength of leadership skills during pediatric crises, has shown promising validity and reliability in simulated settings. The objective of this study was to generate further validity and reliability evidence for the CALM by applying it to real-life emergency events. METHODS: A prospective, video-based study was conducted in an academic pediatric emergency department. Three reviewers independently applied the CALM tool to the assessment of pediatric emergency department physicians as they led both a cardiac arrest and a sepsis event. Time to critical event (epinephrine, fluid, and antibiotic administration) was collected via video review. Based on Kane's framework, we conducted fully crossed, person × event × rater generalizability (G) and decision (D) studies. Interrater reliability was calculated using Gwet AC 2 and intraclass correlation coefficients. Time to critical events was correlated with CALM scores using Spearman coefficient. RESULTS: Nine team leaders were assessed in their leadership of 2 resuscitations each. The G coefficient was 0.68, with 26% subject variance, 20% rater variance, and no case variance. Thirty-three percent of the variance (33%) was attributed to third-order interactions and unknown factors. Gwet AC 2 was 0.3 and intraclass correlation was 0.58. The CALM score and time to epinephrine correlated at -0.79 ( P = 0.01). The CALM score and time to fluid administration correlated at -0.181 ( P = 0.64). CONCLUSIONS: This study provides additional validity evidence for the CALM tool's use in this context if used with multiple raters, aligning with data from the previous simulation-based CALM validity study. Further development may improve reliability. It also serves as an exemplar of the rigors of conducting validity work within medical simulation.

OBJECTIVES: We aimed to develop a standardized scoring tool to measure point-of-care ultrasound (POCUS) image quality and to determine validity evidence for its use to assess lung ultrasound image quality. METHODS: The POCUS Image Quality (POCUS IQ) scale was developed by POCUS-trained physicians to assess sonographers' image acquisition skills by evaluating image quality for any POCUS application. The scale was piloted using lung images of healthy standardized patients acquired by three expert sonographers compared to three novices before and after training. All images (experts, novices pre-training, novices post-training) were scored on the POCUS IQ scale by three blinded POCUS-trained physicians. Reliability was assessed with fully-crossed generalizability and decision studies. Validity was assessed using Messick's framework. RESULTS: Content validity was supported by the tool's development process of literature review, expert consensus, and pilot testing. Response process was supported by reviewer training and the blinded scoring process. Relation to other variables was supported by scores relating to sonographer experience: median expert score = 10.5/14 (IQR: 4), median novice pre-training score = 6/14 (IQR: 2.25), and novices' improvement after training (median post-training score = 12/14, IQR: 3.25). Internal structure was supported by internal consistency data (coefficient alpha = 0.84, omega coefficient = 0.91) and the generalizability study showing the main contributor to score variability was the sonographer (51%). The G-coefficient was 0.89, suggesting very good internal structure, however, Gwet's AC2 was 0.5, indicating moderate interrater reliability. The D study projected a minimum of 1 reviewer and 2 patients are needed for good psychometric reliability. CONCLUSIONS: The POCUS scale has good preliminary validity evidence as an assessment tool for lung POCUS image acquisition skills. Further studies are needed to demonstrate its utility for other POCUS applications and as a feedback tool for POCUS learners.

Ultrasound imaging provides the means for non-invasive real-time diagnostics of the internal structure of soft tissue in living organisms. However, the majority of commercially available ultrasonic transducers have rigid interfaces which cannot conform to highly-curved surfaces. These geometric limitations can introduce a signal-quenching air gap for certain topographies, rendering accurate imaging difficult or impractical. Here, we demonstrate a 256-element flexible two-dimensional (2D) ultrasound piezoelectric transducer array with geometric phase correction. We show surface-conformable real-time B-mode imaging, down to an extreme radius of curvature of 1.5 cm, while maintaining desirable performance metrics such as high signal-to-noise ratio (SNR) and minimal elemental cross-talk at all stages of bending. We benchmark the array capabilities by resolving reflectors buried at known locations in a medical-grade tissue phantom, and demonstrate how phase correction can improve image reconstruction on curved surfaces. With the current array design, we achieve an axial resolution of ≈ 2 mm at clinically-relevant depths in tissue, while operating the array at 1.4 MHz with a bandwidth of ≈ 41%. We use our prototype to image the surface of the human humerus at different positions along the arm, demonstrating proof-of-concept applicability for real-time diagnostics using phase-corrected flexible ultrasound probes.

OBJECTIVE: Interfacility transport of critically ill infants and children is an essential part of the care of children in the United States. However, there is tremendous variation in how transports are coordinated and performed. Pediatric critical care medicine (PCCM) fellows have differing experiences in their fellowships, and there is no standardized way of training medical command for the transport process. The aim of this study was to use a consensus-building process to establish core components of a PCCM transport curriculum focused on communication. METHODS: A national group of experts in transport medicine rated 51 total possible topics for their importance to include in a fellowship curriculum. Three rounds of surveys were completed. RESULTS: Fifty-two of 372 invitees (14%) participated in round 1. Consensus was reached to include 15 items in a PCCM curriculum. Twenty of 52 (38%) experts completed round 2, reaching consensus on 2 additional items. Seventeen of 20 (85%) experts completed round 3. No additional items reached consensus. CONCLUSION: Experts reached consensus on 17 core components to include in a PCCM fellowship transport communication curriculum. This curriculum could likely be adapted to train providers from different disciplines in the transport process.

BACKGROUND: As simulation matures, it is critical to develop pathways for researchers. A recent analysis, however, demonstrates a low conversion rate between abstract and peer-reviewed journal publication in our field. The International Network for Simulation-based Pediatric Innovation, Research, and Education has used the ALERT Presentation process for the past decade as a means of accelerating research. In this study, we analyze the scholarly products attributable to ALERT Presentations. METHODS: Surveys were distributed to all International Network for Simulation-based Pediatric Innovation, Research, and Education Advanced Look Exploratory Research Template (ALERT) Presentation first authors from January 2011 through January 2020. Presenters were asked to provide information on abstracts, grants, journal publications, and book chapters related to their ALERT Presentation, as well as basic demographic information. A structured literature search was conducted for those ALERT Presentations whose authors did not return a survey. The resulting database was descriptively analyzed, and statistical correlations between demographic variables and scholarship were examined. RESULTS: One hundred sixty-five new ALERT presentations were presented over 10 years. We identified 361 associated scholarly works (170 conference abstracts, 125 peer-reviewed journal publications, 65 grants, and 1 book chapter). Sixty-one percent (101 of 165) of ALERT Presentations produced at least 1 item of scholarship, and 59% (34 of 58) of ALERT Presentations that resulted in at least 1 abstract also led to at least 1 peer-reviewed journal article. Presenter gender was associated with likelihood of journal publication. CONCLUSIONS: The ALERT Presentation process is an effective approach for facilitating the development of projects that result in disseminated scholarship. Wider adoption may benefit other simulation and education research networks.

SUMMARY STATEMENT: A decade ago, at the time of formation of the International Network for Pediatric Simulation-based Innovation, Research, and Education, the group embarked on a consensus building exercise. The goal was to forecast the facilitators and barriers to growth and maturity of science in the field of pediatric simulation-based research. This exercise produced 6 domains critical to progress in the field: (1) prioritization, (2) research methodology and outcomes, (3) academic collaboration, (4) integration/implementation/sustainability, (5) technology, and (6) resources/support/advocacy. This article reflects on and summarizes a decade of progress in the field of pediatric simulation research and suggests next steps in each domain as we look forward, including lessons learned by our collaborative grass roots network that can be used to accelerate research efforts in other domains within healthcare simulation science.

OBJECTIVES: Coaches improve cardiopulmonary (CPR) outcomes in real-world and simulated settings. To explore verbal feedback that targets CPR quality, we used natural language processing (NLP) methodologies on transcripts from a published pediatric randomized trial (coach vs. no coach in simulated CPR). Study objectives included determining any differences by trial arm in (1) overall communication and (2) metrics over minutes of CPR and (3) exploring overall frequencies and temporal patterns according to degrees of CPR excellence. METHODS: A human-generated transcription service produced 40 team transcripts. Automated text search with manual review assigned semantic category; word count; and presence of verbal cues for general CPR, compression depth or rate, or positive feedback to transcript utterances. Resulting cue counts per minute (CPM) were corresponded to CPR quality based on compression rate and depth per minute. CPMs were compared across trial arms and over the 18 min of CPR. Adaptation to excellence was analyzed across four patterns of CPR excellence determined by k-shape methods. RESULTS: Overall coached teams experienced more rate-directive, depth-directive, and positive verbal cues compared with noncoached teams. The frequency of coaches' depth cues changed over minutes of CPR, indicating adaptation. In coached teams, the number of depth-directive cues differed among the four patterns of CPR excellence. Noncoached teams experienced fewer utterances by type, with no adaptation over time or to CPR performance. CONCLUSION: NLP extracted verbal metrics and their patterns in resuscitation sessions provides insight into communication patterns and skills used by CPR coaches and other team members. This could help to further optimize CPR training, feedback, excellence, and outcomes.
ABSTRACT
BACKGROUND: Unsafe conditions (UCs) are circumstances that increase the probability of a patient safety event occurring. Each UC identified presents an opportunity to prevent a near miss or adverse patient event through proactive mitigation. The aim of this study was to describe the frequency, characteristics, contributing factors, and potential for harm of reported UCs. METHODS: This is a retrospective descriptive analysis of UC incident reports voluntarily entered into an electronic medical event reporting system at a single tertiary care women and children's hospital. Reports were reviewed and categorized using a previously published classification scheme and a modified Healthcare Failure Mode and Effects Analysis (HFMEA). Reporter role, hospital location, and time to incident resolution were also described. RESULTS: Between July 1, 2016, and June 30, 2019, 348 UCs were entered, representing 3.4% of all reports. Predominant categories of UCs were equipment (43.7%), medication (20.7%), and environmental safety (14.4%). A contributing factor was identified for >99.4% of all UCs, with 77.6% having more than one. Nurses (70.1%) submitted the highest numbers of UCs. The majority of UCs were of mild severity (79.9%) but had the potential to recur frequently (73.3%). CONCLUSION: UCs represented a small proportion of all reported events across the hospital. Equipment and medication issues were important causes of UCs, and most UCs had one or more contributing factors. Though most UCs were of mild severity, they had a predicted potential to recur frequently, representing significant opportunities for improvement.

SUMMARY STATEMENT: Simulation-based education is a particularly germane strategy for addressing the difficult topic of racism and implicit bias due to its immersive nature and the paradigm of structured debriefing. Researchers have proposed actionable frameworks for implicit bias education, particularly outlining the need to shift from recognition to transformation, with the goal of changing discriminatory behaviors and policies. As simulation educators tasked with training health care professionals, we have an opportunity to meet this need for transformation. Simulation can shift behaviors, but missteps in design and implementation when used to address implicit bias can also lead to negative outcomes. The focus of this article is to provide recommendations to consider when designing simulation-based education to specifically address racism and implicit bias.

OBJECTIVES: Effective trainee-led debriefing after critical events in the pediatric emergency department has potential to improve patient care, but debriefing assessments for this context have not been developed. This study gathers preliminary validity and reliability evidence for the Debriefing Assessment for Simulation in Healthcare (DASH) as an assessment of trainee-led post-critical event debriefing. METHODS: Eight fellows led teams in three simulated critical events, each followed by a video-recorded discussion of performance mimicking impromptu debriefings occurring after real clinical events. Three raters assessed the recorded debriefings using the DASH, and their feedback was collated. Data were analyzed using generalizability theory, Gwet's AC2, intraclass correlation coefficient (ICC), and coefficient alpha. Validity was examined using Messick's framework. RESULTS: The DASH instrument had relatively low traditional inter-rater reliability (Gwet's AC2 = 0.24, single-rater ICC range = 0.16-0.35), with 30% fellow, 19% rater, and 23% rater by fellow variance. DASH generalizability (G) coefficient was 0.72, confirming inadequate reliability for research purposes. Decision (D) study results suggest the DASH can attain a G coefficient of 0.8 with five or more raters. Coefficient alpha was 0.95 for the DASH. A total of 90 and 40% of items from Elements 1 and 4, respectively, were deemed "not applicable" or left blank. CONCLUSIONS: Our results suggest that the DASH does not have sufficient validity and reliability to rigorously assess debriefing in the post-critical event environment but may be amenable to modification. Further development of the tool will be needed for optimal use in this context.
ABSTRACT
OBJECTIVES: Multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease 2019 is a novel pediatric condition with significant morbidity and mortality. The primary objective of this investigation was to describe the point-of-care ultrasound (POCUS) findings in patients evaluated in the emergency department (ED) who were diagnosed with MIS-C. METHODS: A retrospective cross-sectional study was conducted including patients <21-years-old who had POCUS performed for clinical care in a pediatric ED and were diagnosed with MIS-C. Point-of-care ultrasound studies were performed by pediatric emergency medicine attending physicians or fellows. Data abstracted by chart review included patient demographics, clinical history, physical examination findings, diagnostic test results, the time POCUS studies and echocardiograms were performed, therapies administered, and clinical course after admission. RESULTS: For the 24 patients included, 17 focused cardiac ultrasound, 9 lung POCUS, 7 pediatric modified rapid ultrasound for shock and hypotension, 1 focused assessment with sonography for trauma, 1 POCUS for suspected appendicitis, and 1 ocular POCUS were performed by 13 physicians. Point-of-care ultrasound identified impaired cardiac contractility in 5 patients, large intraperitoneal free fluid with inflamed bowel in 1 patient, and increased optic nerve sheath diameters with elevation of the optic discs in 1 patient. Trace or small pericardial effusions, pleural effusions, and intraperitoneal free fluid were seen in 3 patients, 6 patients, and 4 patients, respectively. CONCLUSIONS: This study demonstrates the spectrum of POCUS findings in MIS-C. Prospective studies are needed to help delineate the utility of incorporating POCUS into an ED management pathway for patients with suspected MIS-C.

BACKGROUND: Stress may impair the success of procedures in emergency medicine. The aims were to assess residents' stress during simulated and clinical lumbar punctures (LPs) and to explore the correlation of stress and performance. METHODS: A prospective study (2013-2016) was carried out in a pediatric emergency department. A mastery training and subsequently a just-in-time training were conducted immediately preceding each clinical LP. Stress was self-assessed by the Stress-O-Meter scale (0-10). Performance (checklist 0-6 points) and success rate (cerebrospinal fluid with <1000 red blood cells/mm3) were recorded by a trained supervisor. A survey explored self-confidence and potential causes of stress. RESULTS: Thirty-three residents performed 35 LPs. There was no stress during simulation procedure. Stress levels significantly increased for clinical procedure (P < 0.0001). Performance was similar in simulation and in clinic (respectively, 5.50 ± 0.93 vs 5.42 ± 0.83; P = 0.75). Success significantly decreased during clinical LP (P < 0.0001). The 2 most reported stress-related factors were fear of technical errors and personal fatigue. CONCLUSIONS: Performance scores and success rates in simulation are insufficient to predict success in clinical situations. Stress level and stress-related factors (fear of technical errors and personal fatigue) might be different in simulated or real conditions and consequently impact success of a technical procedure even if a high-performance score is recorded.
