Use of High-Fidelity Simulation as an Adjunct to Basic Life Support Training To Promote Team-Based Resuscitation Skills: A Mixed-Methods Pilot Study.

Introduction The 2020 American Heart Association's (AHA) Basic Life Support (BLS) curriculum focuses on cardiac arrest resuscitation with one or two rescuers, providing only limited opportunities to develop higher-level skills such as leadership, communication, and debriefing. This mixed-methods pilot study evaluated whether supplementing the traditional Heartcode BLS course with a high-fidelity teamwork simulation session improved mastery of these higher-level skills. Methods Twenty-four first-year medical students completed the pilot training during sessions offered in February and May of 2023. The program included the traditional AHA Heartcode BLS course, which ranges from two to four hours, and includes both online and in-person skills components. This was followed by a 90-minute high-fidelity simulation session consisting of two simulated resuscitationsseparated by a student-led plus/delta debriefing. Facilitators then debriefed the entire activity. Students completed an anonymous online survey that used a 0-10 slider scale to attribute their perceived proficiency for specific skills to the initial BLS course or the teamwork simulations and provided qualitative feedback. Results Twenty-one students (87.5%) completed the follow-up survey. Students credited their proficiency in technical skills (e.g., "Chest Compressions") to both sessions equally, but proficiency in higher-level skills, such as leadership, communication, and teamwork, was predominantly credited to the simulation. Additionally, students reported that the teamwork simulation promoted realism and increased self-efficacy. Conclusion Team-based resuscitation simulations using high-fidelity equipment augmented the AHA BLS course by promoting perceived competence in team dynamics domains and increasing students' self-efficacy for participating in real hospital-based resuscitations. Studies with larger sample sizes and objective data should be performed, and the use of similar resuscitation simulations or the development of a formal team-based BLS certification course should be considered.

RiNeo MR: A mixed reality simulator for newborn life support training.

Neonatal resuscitation is an uncommon, albeit critical task that is more likely to succeed if performed properly and promptly. In this context, simulation is an appropriate way for training and assessing the abilities of all medical staff involved in delivery room care. Recent studies have shown that learning is enhanced if the simulation experience is realistic and engaging. Hence, Virtual Reality can be beneficial for newborn resuscitation training. However, the difficulty of providing realistic haptic interaction limits its use. To overcome this constraint, we have designed RiNeo MR, a simulator for newborn life support training, combining a sensorized manikin to monitor in real time resuscitation skills, with a Virtual Reality application. The system includes a Virtual Reality headset, Leap Motion to track the user's hands, sensorized bag valve mask, and manikin to monitor head and mask positioning, ventilation, and chest compression. RiNeo MR can be used in two modalities: 2D to let the trainee practice resuscitation manoeuvres on the physical manikin, while receiving real time feedback; 3D that allows the user to be immersed in a virtual environment and practice in an hospital-like setting. In the 3D mode, virtual and real manikins are overlapped and communicate in real time. Tests on 16 subjects (11 controls without medical expertise and 5 paediatric residents) demonstrated that the simulator is well tolerated in terms of discomfort. Moreover, the simulator is high rated for user experience and system usability, suggesting that RiNeo MR can be a promising tool to improve newborn life support training. RiNeo MR is a proof of concept of a mixed-reality newborn life support simulator that can be a promising tool to spread newborn resuscitation high-quality training among healthcare providers involved in perinatal medicine.

The effect of simulation-based advanced cardiac life support training on nursing students’ self-efficacy, attitudes, and anxiety in Palestine: a quasi-experimental study

BackgroundCardiac Arrest (CA) is one of the leading causes of death, either inside or outside hospitals. Recently, the use of creative teaching strategies, such as simulation, has gained popularity in Cardio Pulmonary Resuscitation (CPR) instruction. This study aimed to assess the effect of High-Fidelity Simulation (HFS) training on nursing students’ self-efficacy, attitude, and anxiety in the context of Advanced Cardiac Life Support (ACLS).MethodologyThe study design is quasi-experimental employing a pre-test and post-test approach during April and May 2023. A convenient sample of 60 undergraduate nursing students in a 4-year class from a nursing college at the Arab American University/ Palestine (AAUP) participated in this study. The data were analyzed using a paired sample t-test in SPSS program version 26. Three data collection tools were used pre- and post-intervention; the Resuscitation Self-Efficacy Scale (RSES), The Attitudinal instrument, and the State Anxiety Inventory (SAI).ResultsThe total number of nursing students was 60, out of them (56.7%) were female, while the mean age was (22.2) years. Improvements were seen in all four domains of self-efficacy following HFS training: recognition, debriefing, recording, responding and rescuing, and reporting. (t (59) = 26.80, p < 0.001, confidence interval [29.32, 34.05]). After receiving HFS training on ACLS, the post-intervention for the same group attitude scores significantly increased from 32.83 (SD = 15.35) to 54.58 (SD = 8.540) for emotion, from 6.72 (SD = 2.44) to 10.40 (SD = 1.40) for behavior, and from 7.03 (SD = 2.03) to 10.33 (SD = 1.42) for cognitive. The anxiety level decreased post-simulation from 3.53 (SD = 0.3) to 2.14 (SD = 0.65), which was found to be statistically significant (t(59) = 16.68, p < 0.001, 95% CI [1.22 to 1.55]). Female students (M = 73.18), students who observed a real resuscitation (M = 71.16), and who were satisfied with their nursing major (M = 72.17) had significantly higher self-efficacy scores post-simulation.ConclusionThe HFS can be recommended as an effective training strategy among nursing students. The ACLS training-based HFS was effective in improving the students’ self-efficacy and attitudes and decreasing their anxiety.

Release velocity improvement with a new metronome-guided chest compression protocol: preliminary results of the RITMICO study

Abstract Introduction Annually, emergency medical services treat over 350’000 out-of-hospital cardiac arrests in the U.S. and over 25’000 in Europe. Outcomes vary widely, according also to the quality of the CardioPulmonary Resuscitation (CPR) provided. Recently, it was demonstrated how, on top of the compression phase, chest release phase is also important to obtain an adequate heart and brain perfusion. However, no studies describe how to ameliorate this parameter during resuscitation. Purpose We investigated if a modified metronome-guided procedure might improve chest compression release velocity during CPR simulation on standard manikin, compared to the standard procedure. Methods We developed a double-click metronome for CPR: the first click corresponds to chest compression and the second to the end of chest release. Volunteers with different levels of expertise in CPR and with a valid BLS-D certification have been included in the study. Each subject performed two CPR manikin simulations following a 4-min protocol with the standard and the modified metronome (Figure 1), in a random order. An Automated External Defibrillator (AED) equipped with pads allowed continuous measurement of CPR quality during simulations. Three CPR parameters have been measured: compression depth, rate and release velocity. CPR simulation was guided only by the external metronome, all audio prompts from the AED were silenced. The two procedures have been compared, in terms of CPR quality, using Wilcoxon signed-ranks test. Impact of subject-specific factors on the difference in CPR quality has been evaluated using stepwise regression. Results 151 volunteers were included in the study, 23 of them have been excluded due to incomplete data recording. Comparison between the two procedures (Figure 2) showed a significant increase of median chest compression depth (p&amp;lt;&amp;lt;0.001) and release velocity (p&amp;lt;0.05) with the modified metronome. Percentage of compressions within the optimal range was significantly higher for compression depth (p&amp;lt;0.05) and significantly lower for compression rate (p&amp;lt;0.01) with the modified metronome. Chest compression release velocity difference was not statistically significant (p=0.20). No significant impact of sex, age and level of expertise was observed. Conclusions The double-click metronome significantly increased CPR quality in terms of both compression depth and release velocity. The decrease of compressions within the optimal rate range in the modified procedure could be due to lack of familiarity with the new rhythm and needs further evaluation. Our study represents the first trial trying to improve chest compression release velocity. Demonstrating the efficacy of this procedure could pave the way to clinical trials in real resuscitations to confirm the potential impact on the outcome of out-of-hospital cardiac arrest.Study protocolComparison between the two procedures

Gamification of a Low-Fidelity Paper Doll to Teach Primary Survey to Pediatric Residents.

When critically ill pediatric patients arrive in the emergency department (ED), a rapid physical evaluation is performed in order to systematically evaluate and address life-threatening conditions. This is commonly referred to as the primary survey. At our institution, pediatricresidents are frequently tasked with this role, but they have limited training for or experience with this task. Quality improvement review of real resuscitation recordings at our institution revealed delays in initiation and incomplete primary surveys.We sought to utilize gamification to standardize and optimize reproducible training for the primary survey task for pediatricresidents using a low-fidelity paper doll model simulation to improve primary survey performance in actual resuscitations.

Team communication patterns during real and simulated trauma resuscitation—a social network analysis

In trauma teams, coordination can be established through a centralised leader. The team can also use a decentralised strategy. In this descriptive study of video-recorded trauma resuscitations, using quantification of qualitative data, Social Network analysis of all real-time communications of eight in-real-life (IRL) and simulated trauma teams explained team social structure. The communication network structures in the simulated scenarios were more centralised using individually directed speech and had a high proportion of communication to update all team members. Such a structure might be the result of work performed in a complexity-stripped simulation environment where simplified task-executions required less interactions, or from work revolving around a deteriorating patient, imposing high demands on rapid decision-making and taskwork. Communication IRL was mostly decentralised, with more variability between cases, possibly due to unpredictability of the IRL case. The flexibility to act in a decentralised manner potentiates adaptability and seems beneficial in rapidly changing situations. Practitioner summary: Efficient collaboration in trauma teams is essential. Communication in in-real-life and simulated trauma teams was analysed using social network analysis. The simulation teams were overall more centralised compared to the IRL teams. The flexibility to act decentralised seems beneficial for emergency teams as it enables adaptability in unpredictable situations.

A Systematic Review of Heart Rate Variability as a Measure of Stress in Medical Professionals.

Understanding the physiological effects of responding to crises is a critical component in understanding how to manage and prepare medical professionals to be crisis responders. Heart rate variability (HRV) is the variation in rate between a succession of R-R intervals. This variation is not only affected by physiological processes such as respiration or metabolic rate but is also directly controlledby the autonomic nervous system. As such, heart rate variability has been proposed as a noninvasive tool to measure the physiological stress response. The aim of this systematic review is to consolidate heart rate variability literature in the context of medical emergencies to determine if heart rate variability changes predictably from baseline when responding to medical crises. This may demonstrate utility as an objective, noninvasive measure of stress response. A systematic literature review of six databases yielded 413 articles, 17 of which met our inclusion criteria of being written in English, measuring HRV in healthcare providers, and measuring HRV in real or simulated medical resuscitations or procedures. Articles were then analyzed using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) scoring system. Out of the 17 articles reviewed, 11 demonstrated statistically significant results showing heart rate variability responding in a predictable manner to stress. Three articles utilized a medical simulation as the stressor, six used medical procedures, and eight used medical emergencies encountered during clinical work. Overall, a predictable trend in heart rate variability metrics of standard deviation from the mean value of normal-to-normal(N-N) intervals (SDNN), root mean square of the successive differences (RMSSD),mean number of times per time interval in which the change in successive normal sinus (N-N) intervals exceeds 50 ms (PNN50), low frequency % (LF%), and low-frequency-to-high-frequency ratio (LF/HF) was observed when responding to stress. This systematic literature review showed that heart rate variability among healthcare providers responding to stressful scenarios follows a predictable pattern of change and expands our understanding of the physiology of stress in healthcare providers. This review supports the use of HRV to monitor stress during high-fidelity simulation to ensure that appropriate physiological arousal is achieved during the training of medical personnel.

Development and psychometric properties of teamwork scale in resuscitation: A sequential exploratory mixed-method study.

Non-technical skills as a complement to technical skills have become increasingly important in cardio-pulmonary resuscitation, and teamwork is one of the most prominent of these skills. Because of the limited number of tools introduced and validated for measuring teamwork in resuscitation, this study was conducted to develop and evaluate the psychometric properties of the Teamwork Scale in Resuscitation (TSR). This study was a sequential exploratory mixed-method study and was conducted between March 2020 and April 2021 and in two phases. In the first phase (qualitative), semi-structured interviews were performed with resuscitation team members who were selected using a purposeful sampling method with maximum variation in terms of experience, level of education, age, and gender. Using directed qualitative content analysis, the data were analyzed and the primary item pool was developed. In the second phase (quantitative), assessing face, content, and construct validity as well as reliability via the internal consistency and stability, the psychometric properties of the instrument are evaluated. The initial tool consisted of 54 items; after assessing the face validity, ten items were removed during content validity, and the final tool consisted of 44 items and three main categories including the essential prerequisites for resuscitation, leadership, and teamwork, which was scored based on a 5-point Likert scale from strongly disagree to strongly agree. The convergent validity and concurrent validity of the tool were confirmed. The reliability of the instrument was also confirmed using Cronbach's alpha test and re-test and the intra-class correlation coefficient (ICC) between raters. The validity and reliability of TSR for measuring teamwork in resuscitation in a simulated environment are approved. Further studies are suggested for different contexts of resuscitation and with trained raters to evaluate its use in real resuscitation situations.

Newborn resuscitation simulation training and changes in clinical performance and perinatal outcomes: a clinical observational study of 10,481 births

BackgroundAnnually, 1.5 million intrapartum-related deaths occur; fresh stillbirths and early newborn deaths. Most of these deaths are preventable with skilled ventilation starting within the first minute of life. Helping Babies Breathe is an educational program shown to improve simulated skills in newborn resuscitation. However, translation into clinical practice remains a challenge. The aim was to describe changes in clinical resuscitation and perinatal outcomes (i.e., fresh stillbirths and 24-h newborn deaths) after introducing a novel simulator (phase 1) and then local champions (phase 2) to facilitate ongoing Helping Babies Breathe skill and scenario simulation training.MethodsThis is a 3-year prospective before/after (2 phases) clinical observational study in Tanzania. Research assistants observed all deliveries from September 2015 through August 2018 and recorded labor/newborn information and perinatal outcomes. A novel simulator with automatic feedback to stimulate self-guided skill training was introduced in September 2016. Local champions were introduced in October 2017 to motivate midwives for weekly training, also team simulations.ResultsThe study included 10,481 births. Midwives had practiced self-guided skill training during the last week prior to a real newborn resuscitation in 34% of cases during baseline, 30% in phase 1, and 71% in phase 2. Most real resuscitations were provided by midwives, increasing from 66% in the baseline, to 77% in phase 1, and further to 83% in phase 2. The median time from birth to first ventilation decreased between baseline and phase 2 from 118 (85–165) to 101 (72–150) s, and time pauses during ventilation decreased from 28 to 16%. Ventilations initiated within the first minute did not change significantly (13–16%). The proportion of high-risk deliveries increased during the study period, while perinatal mortality remained unchanged.ConclusionsThis study reports a gradual improvement in real newborn resuscitation skills after introducing a novel simulator and then local champions. The frequency of trainings increased first after the introduction of motivating champions. Time from birth to first ventilation decreased; still, merely 16% of newborns received ventilation within the first minute as recommended. This is a remaining challenge that may require more targeted team-scenario training and quality improvement efforts to improve.

Evaluation of mountain rescuers’ (non-)technical skills during simulated resuscitation

Mountain rescuers work voluntarily but must provide high-quality cardiopulmonary resuscitations (CPR). As demands for their services rise, the factors influencing CPR skills are investigated. Research has shown that technical skills (TS), non-technical skills (NTS), experience, experienced patient deaths, and monitoring impact resuscitation performance. This study explores the influence of these factors for this kind of voluntary medical personnel. A total of 103 mountain rescuers participated. A specially created NTS observation form, questionnaires and simulation manikin were used to measure NTS, TS, experience, and monitoring skills. Results indicate that NTS and TS did not correlate significantly. Only the number of real resuscitations differed significantly between the TS of experienced and inexperienced mountain rescuers. Experienced patient deaths were not significantly related to CPR performance. Furthermore, mountain rescuers could not fully correctly assess their colleagues during simulation. The study shows that previous research results might not hold true in a different medical domain.

An analysis of trauma team communication using the verbal response mode taxonomy

BackgroundAlthough 40 years has passed since the Institute of Medicine released its report “To Err Is Human,” error counts are still high in healthcare. The understanding and training of nontechnical skills and teamwork thus remains a pertinent area for improvement. Most evaluation of nontechnical skills of trauma teams takes place in simulation rooms. The aim of this study was to determine if real trauma resuscitation communication could be analyzed using the speech classification system of verbal response modes, otherwise known as the verbal response mode taxonomy and, if so, if there is a predominant approach of verbally delivering messages. MethodsVideo and audio recordings of 5 trauma team resuscitations were transcribed. Communication was coded using the verbal response mode taxonomy for both form and intent. The rate of mixed-mode communication (unmatched form and intent) and pure-mode communication were calculated and compared between the participants roles. Comparisons were made with simulated material published in other research. ResultsThe most frequent mixed-mode communication was acknowledgment in service of confirmation. Question in service of a question was the most used pure-mode communication. Six predominant roles were seen, which matched well with the roles in the simulations. ConclusionThe verbal response mode taxonomy can be used to study communication during real trauma resuscitation, and it was found that pure-mode communication was predominant, meaning that the grammatical form matches the intent. Verbal response mode methodology is time consuming and requires analysts with domain knowledge. Comparisons show some differences between simulations and our material indicating that verbal response modes can be used to evaluate differences in communication.

Do automated real-time feedback devices improve CPR quality? A systematic review of literature

AimAutomated real-time feedback devices have been considered a potential tool to improve the quality of cardiopulmonary resuscitation (CPR). Despite previous studies supporting the usefulness of such devices during training, others have conflicting conclusions regarding its efficacy during real-life CPR. This systematic review aimed to assess the effectiveness of automated real-time feedback devices for improving CPR performance during training, simulation and real-life resuscitation attempts in the adult and paediatric population. MethodsArticles published between January 2010 and November 2020 were searched from BVS, Cinahl, Cochrane, PubMed and Web of Science, and reviewed according to a pre-defined set of eligibility criteria which included healthcare providers and randomised controlled trial studies. CPR quality was assessed based on guideline compliance for chest compression rate, chest compression depth and residual leaning. ResultsThe selection strategy led to 19 eligible studies, 16 in training/simulation and three in real-life CPR. Feedback devices during training and/or simulation resulted in improved acquisition of skills and enhanced performance in 15 studies. One study resulted in no significant improvement. During real resuscitation attempts, three studies demonstrated significant improvement with the use of feedback devices in comparison with standard CPR (without feedback device). ConclusionThe use of automated real-time feedback devices enhances skill acquisition and CPR performance during training of healthcare professionals. Further research is needed to better understand the role of feedback devices in clinical setting.

Coronavirus-19 Multisystem Inflammatory Syndrome in Children (MIS-C): A Pediatric Simulation Case for Residents, Fellows, and Advanced Practice Providers.

IntroductionA rare but serious condition often requiring intensive care, multisystem inflammatory syndrome in children (MIS-C) is characterized by hyperinflammatory shock related to the SARS-CoV-2 pandemic. This resource teaches residents, pediatric emergency medicine fellows, and advanced practice providers who care for children to recognize and manage MIS-C and associated sequelae while applying the basic principles of pediatric resuscitation.MethodsThe simulation case was based on a real patient who presented to the emergency department with fever, rash, and cardiogenic shock. We designed the scenario to be used with a high-fidelity school-age mannequin in an emergency center resuscitation room or simulation lab. The case took 25 minutes to run, followed by a 15- to 20-minute debrief session. Personnel required for the case included a simulation technician, case instructor, emergency department nurse, parent, and consultant. Learners had to recognize the syndrome and treat the resultant shock and arrhythmia with a combination of vasopressors, antiarrhythmics, and defibrillation. Afterward, learners participated in a formal debriefing session and completed a written evaluation.ResultsTwenty-five learners (six pediatric emergency medicine fellows, 12 residents, and seven advanced practice providers) participated in the scenario over a 3-month period. The written evaluation was completed by 20 of the 25 participants; all 20 felt their confidence, comfort, and knowledge regarding the topic had increased, with an average score of 5 (strongly agree) on a 5-point Likert scale.DiscussionThis simulation case offers an effective experience for learners to become comfortable and confident in recognizing and managing MIS-C.

Comparisons of Stress Physiology of Providers in Real-Life Resuscitations and Virtual Reality-Simulated Resuscitations.

Virtual reality (VR) is a promising simulation medium for high-stakes, low-frequency events such as pediatric resuscitation. The psychological fidelity of VR compared with a real resuscitation in an emergency department (ED) is relatively unknown. The objective was to determine whether stress physiology changes were equivalent between ED and VR resuscitations. This was a single-site pilot equivalence study evaluating head-mounted VR resuscitation scenarios using board-certified/eligible pediatric ED physicians. Subjects had heart rates (HRs) and salivary cortisol levels recorded throughout 8-hour evening ED shifts and during one 1-hour VR session. Additional samples and subjective workload perception (NASA Task Load Index) were collected for critical resuscitations. A delta HR and delta cortisol level described the difference in mean HR and mean cortisol level between shifts with and shifts without resuscitations. Another delta calculation was performed from pre-VR to post-VR. Nonparametric univariate statistics was examined for significant differences in delta HR or cortisol levels between the ED setting and VR. Sixteen subjects had 69 shifts monitored with 31 resuscitations. In the ED, delta HR was +13.9 bpm (P < 0.001) and delta cortisol was +0.10 μg/dL (P = 0.006). In VR, delta HR was +6.5 bpm (P < 0.001) but minimal delta cortisol (-0.02 μg/dL, P = 0.05). Emergency department resuscitations both HR and cortisol levels were more than VR resuscitations (P < 0.03). NASA Task Load Index scores were higher in VR resuscitations with +26 score difference (P = 0.01). Virtual reality resuscitations increase HR but show less stress physiology changes than ED resuscitations within an actual 8-hour shift. Further inquiry into stress physiology and optimal VR simulation is warranted.

Video performance-debriefings and ventilation-refreshers improve quality of neonatal resuscitation

AimProviders caring for newly born infants require skills and knowledge to initiate prompt and effective positive pressure ventilation (PPV) if the newborn does not breathe spontaneously after birth. We hypothesized implementation of high frequency/short duration deliberate practice training and post event video-based debriefings would improve process of care and decreases time to effective spontaneous respiration. MethodsPre- and post-interventional quality study performed at two Norwegian university hospitals. All newborns receiving PPV were prospectively video-recorded, and initial performance data guided the development of educational interventions. A priori primary outcome was changed from process of care using the Neonatal Resuscitation Performance Evaluation (NRPE) score to time to effective spontaneous respiration as the NRPE score could only be obtained from one site due to lack of staff resources. ResultsOver 12 months, 297 PPV-Refreshers and 52 performance debriefings were completed with 227 unique providers attending a PPV-Refresher and 93 unique providers completed a debriefing. We compared 102 PPV-events pre- to 160 PPV-events post-bundle implementation. The time to effective spontaneous respiration decreased from median (95% confidence interval) 196 (140–237) to 144 (120–163) s, p = 0.010. The NRPE-score increased significantly from median 77% (75–81) pre- to 89% (86–92) post-implementation, p < 0.001. There were no significant differences in time to heart rate >100 beats/min or number of newborns transferred to intensive care. ConclusionHigh frequency/short duration deliberate practice PPV psychomotor training combined with performance-focused team debriefings using video recordings of actual resuscitations may improve time to effective spontaneous breathing and adherence to guidelines during real neonatal resuscitations.

Regular, in-situ, team-based training in trauma resuscitation with video debriefing enhances confidence and clinical efficiency

BackgroundTo assess the clinical impact of a regular, multidisciplinary, video debriefed training intervention for trauma team members on real trauma resuscitations. In addition, attending personnel evaluated the training program via questionnaire.MethodsThe training intervention is a regular (monthly), video debriefed, team-based trauma simulation. Training takes place in the fully functional resuscitation bay (in-situ) of the Department of Traumatology at the Klinikum Oldenburg (Level 1, primary teaching hospital for the Carl von Ossietzky University Oldenburg) involving a complete trauma team. Laerdal® Resusci Anne® dummy serves as the patient simulator. A special feature is a structured video debriefing of each participating team to analyse team performance. Data before and after implementation of training was retrospectively analysed.ResultsWe found a significant decrease in the time from arrival of the patient to computer tomography (CT, Spearman rank coefficient r = − 0.236, p = 0.001). Evaluation of the questionnaire by team members described a significant increase in self-confidence (p < 0.05).ConclusionMonthly video assisted team based in situ training with video debriefing significantly reduces resuscitation time in the emergency bay.

Duration to Establish an Emergency Vascular Access and How to Accelerate It: A Simulation-Based Study Performed in Real-Life Neonatal Resuscitation Rooms.

To compare the duration to establish an umbilical venous catheter and an intraosseous access in real hospital delivery rooms and as a secondary aim to assess delaying factors during establishment and to provide recommendations to accelerate vascular access in neonatal resuscitation. Retrospective analysis of audio-video recorded neonatal simulation training. Simulation training events in exact replications of actual delivery/resuscitation rooms of 16 hospitals with different levels of care (Austria and Germany). Equipment was prepared the same way as for real clinical events. Medical teams of four to five persons with birth-related background (midwives, nurses, neonatologists, and anesthesiologists) in a realistic team composition. Audio-video recorded mannequin-based simulated resuscitation of an asphyxiated newborn including the establishment of either umbilical venous catheter or intraosseous access. The duration of access establishment (time from decision to first flush/aspiration), preparation (decision to start of procedure), and the procedure itself (start to first flush/aspiration) was significantly longer for umbilical venous catheter than for intraosseous access (overall duration 199 vs 86 s). Delaying factors for umbilical venous catheter establishment were mainly due to the complex approach itself, the multitude of equipment required, and uncertainties about necessary hygiene standards. Challenges in intraosseous access establishment were handling of the unfamiliar material and absence of an intraosseous access kit in the resuscitation room. There was no significant difference between the required duration for access establishment between large centers and small hospitals, but a trend was observed that duration for umbilical venous catheter was longer in small hospitals than in centers. Duration for intraosseous access was similar in both hospital types. Vascular access establishment in neonatal resuscitation could be accelerated by infrastructural improvements and specific training of medical teams. In simulated in situ neonatal resuscitation, intraosseous access is faster to establish than umbilical venous catheter. Future studies are required to assess efficacy and safety of both approaches in real resuscitation settings.

A method to differentiate between ventricular fibrillation and asystole during chest compressions using artifact-corrupted ECG alone

In recent years, numerous adaptive filtering techniques have been developed to suppress the chest compression (CC) artifact for reliable analysis of the electrocardiogram (ECG) rhythm without CC interruption. Unfortunately, the result of rhythm diagnosis during CCs is still unsatisfactory in many studies. The misclassification between corrupted asystole (ASY) and corrupted ventricular fibrillation (VF) is generally regarded as one of the major reasons for the poor performance of reported methods. In order to improve the diagnosis of VF/ASY corrupted by CCs, a novel method combining a least mean-square (LMS) filter and an amplitude spectrum area (AMSA) analysis was developed based only on the analysis of the surface of the corrupted ECG episode. This method was tested on 253 VF and 160 ASY ECG samples from subjects who experienced cardiac arrest using a porcine model and was compared with six other algorithms. The validation results indicated that this method, which yielded a satisfactory result with a sensitivity of 93.3%, a specificity of 96.3% and an accuracy of 94.8%, is superior to the other reported techniques. After improvement using the human ECG records in real cardiopulmonary resuscitation (CPR) scenarios, the algorithm is promising for corrupted VF/ASY detection with no hardware alterations in clinical practice.

Analysis and classification of errors made by teams during neonatal resuscitation

AimThe Neonatal Resuscitation Program (NRP) algorithm serves as a guide to healthcare professionals caring for neonates transitioning to extrauterine life. Despite this, adherence to the algorithm is challenging, and errors are frequent. Information-dense, high-risk fields such as air traffic control have proven that formal classification of errors facilitates recognition and remediation. This study was performed to determine and characterize common deviations from the NRP algorithm during neonatal resuscitation. MethodsAudiovisual recordings of 250 real neonatal resuscitations were obtained between April 2003 and May 2004. Of these, 23 complex resuscitations were analyzed for adherence to the contemporaneous NRP algorithm and scored using a novel classification tool based on the validated NRP Megacode Checklist. ResultsSeven hundred eighty algorithm-driven tasks were observed. One hundred ninety-four tasks were completed incorrectly, for an average error rate of 23%. Forty-two were errors of omission (28% of all errors) and 107 were errors of commission (72% of all errors). Many errors were repetitive and potentially clinically significant: failure to assess heart rate and/or breath sounds, improper rate of positive pressure ventilation, inadequate peak inspiratory and end expiratory pressures during ventilation, improper chest compression technique, and asynchronous PPV and CC. ConclusionsErrors of commission, especially when performing advanced life support interventions such as positive pressure ventilation, intubation, and chest compressions, are common during neonatal resuscitation and are sources of potential harm. The adoption of error reduction strategies capable of decreasing cognitive and technical load and standardizing communication – strategies common in other industries – should be considered in healthcare.

Introducing Teamwork Challenges in Simulation Using Game Cards.

Poor teamwork and communication during resuscitations are linked to patient safety problems and poorer outcomes. We present a novel simulation-based educational intervention using game cards to introduce challenges in teamwork. This intervention uses sets of game cards that designate roles, limitations, or communication challenges designed to introduce common communication or teamwork problems. Game cards are designed to be applicable for any simulation-based scenario and are independent from patient physiology. In our example, participants were pediatric emergency medicine fellows undergoing simulation training for orientation. We describe the use of card sets in different scenarios with increasing teamwork challenge and difficulty. Both postscenario and summative debriefings were facilitated to allow participants to reflect on their performance and discover ways to apply their strategies to real resuscitations. In this article, we present our experience with the novel use of game cards to modify simulation scenarios to improve communication and teamwork skills.
