Resuscitation education science meets virtual and augmented reality: Evolution from potential concept to recommendations

Aim of the study

This study aims to examine the evolution of recommendations for integrating Virtual Reality (VR) and Augmented Reality (AR) into adult Basic Life Support (BLS) education over time.

Data sources

In December 2024, we conducted a two-phase search. First, we identified and reviewed publications available on the International Liaison Committee on Resuscitation (ILCOR) webpage, focusing on resuscitation education science, specifically addressing VR and/or AR in adult BLS education. In the second phase, we reviewed the references and citations of the included publication to identify relevant publications from the American Heart Association (AHA), European Resuscitation Council (ERC), and ILCOR.

Results

Across both phases, we included 29 AHA, ERC, and ILCOR publications on resuscitation education. These comprised 16 ILCOR CoSTRs, seven AHA/ERC guidelines (four ERC, three AHA), three ILCOR scientific statements, two AHA scientific statements, and one ILCOR review. The first mention of VR appeared in 2003, but the first recommendation was provided in 2020 AHA guidelines, suggesting its use for adult BLS training based on very low-quality evidence. In 2024, the ILCOR CoSTRs issued a weak recommendation supporting AR and a weak recommendation against VR for adult BLS training, both based on very low-quality evidence.

Conclusion

While VR/AR is gaining traction in resuscitation training, its effectiveness remains debated. Initially focused on professionals, it now extends to laypersons and schoolchildren. However, strong evidence is lacking. Future research should assess learning outcomes, guideline adherence, and patient impact to support stronger ILCOR recommendations.

Pediatric Resuscitation Skill of Bag-Tube Manual Ventilation: Developing and Using a Mobile Simulation Program to Assess Competency of a Multiprofessional PICU Team

OBJECTIVES

To assess the skill of bag-tube manual ventilation with the flow-inflating bag in multiprofessional PICU team members using a mobile simulation unit.

DESIGN

Prospective observational study from January 2022 to April 2022.

SETTING

In situ mobile simulation using the flow-inflating bag in an academic PICU.

SUBJECTS

Multiprofessional PICU team members including nurses, respiratory therapists, nurse practitioners, fellows, and attendings.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We enrolled 129 participants who twice completed 1-minute tasks performing bag-tube manual ventilation with a flow-inflating bag. Sessions were video recorded; four could not be analyzed. Only 30% of participants reported being very to extremely confident, and the majority (62%) reported infrequent skill performance. Task success was defined as achieving target pressure ranges during 80% of the delivered breaths, respiratory rate (RR) of 25-35 breaths/min, and successful pop-off valve engagement. Only five of 129 participants (4%) achieved successful ventilation as defined. Overall, participants were more likely to deliver lower pressures and faster rate. Maintaining target positive end-expiratory pressure (PEEP) was least likely to be achieved (19% success), followed by RR (52%), pop-off valve (64%), then peak inspiratory pressure (71%). Nurses were less likely to achieve target pressures compared with all other professions.

CONCLUSIONS

Multiprofessional PICU team members have highly variable self-confidence with bag-tube manual ventilation using a flow-inflating bag. Observed performance demonstrates rare success with achieving targeted ventilation parameters, in particular maintenance of PEEP. Future research should focus on developing mobile simulation units to facilitate profession-specific, real-time coaching to teach high-quality manual ventilation that can be translated to the bedside.

Influence of Training With Corrective Feedback Devices on Cardiopulmonary Resuscitation Skills Acquisition and Retention: Systematic Review and Meta-Analysis

BACKGROUND

Several studies related to the use of corrective feedback devices in cardiopulmonary resuscitation training, with different populations, training methodologies, and equipment, present distinct results regarding the influence of this technology.

OBJECTIVE

This systematic review and meta-analysis aimed to examine the impact of corrective feedback devices in cardiopulmonary resuscitation skills acquisition and retention for laypeople and health care professionals. Training duration was also studied.

METHODS

The search was conducted in PubMed, Web of Science, and Scopus from January 2015 to December 2023. Eligible randomized controlled trials compared technology-based training incorporating corrective feedback with standard training. Outcomes of interest were the quality of chest compression-related components. The risk of bias was assessed using the Cochrane tool. A meta-analysis was used to explore the heterogeneity of the selected studies.

RESULTS

In total, 20 studies were included. Overall, it was reported that corrective feedback devices used during training had a positive impact on both skills acquisition and retention. Medium to high heterogeneity was observed.

CONCLUSIONS

This systematic review and meta-analysis suggest that corrective feedback devices enhance skills acquisition and retention over time. Considering the medium to high heterogeneity observed, these findings should be interpreted with caution. More standardized, high-quality studies are needed.

2024 American Heart Association and American Academy of Pediatrics Focused Update on Special Circumstances: Resuscitation Following Drowning: An Update to the American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care

Drowning is the third leading cause of death from unintentional injury worldwide, accounting for 7% of all injury-related deaths. The World Health Organization estimates that there are ≈236 000 deaths due to drowning worldwide each year. Significant efforts have focused on creating systems to prevent drowning, but an average of 4000 fatal and 8000 nonfatal drownings still occur annually in the United States-likely an underestimate. Drowning generally progresses from initial respiratory arrest due to submersion-related hypoxia to cardiac arrest; thus, it can be challenging to distinguish respiratory arrest from cardiac arrest because pulses are difficult to accurately palpate within the recommended 10-second window. Therefore, resuscitation from cardiac arrest attributable to this specific circumstance must focus on restoring breathing as much as it does circulation. Resuscitation from drowning may begin with in-water rescue breathing when safely provided by rescuers trained in the technique and should continue with chest compressions, in keeping with basic life support guidelines, once the drowned individual and the rescuer are in a safe environment (eg, dry land, a boat). This focused update incorporates systematic reviews from 2021 to 2023 performed by the International Liaison Committee on Resuscitation related to the resuscitation of drowning. These clinical guidelines are the product of a committee of experts representing the American Heart Association and the American Academy of Pediatrics. The writing group reviewed the recent International Liaison Committee on Resuscitation systematic reviews, including updated literature searches, prior guidelines related to resuscitation from cardiac arrest following drowning, and other drowning-related publications from the American Heart Association and American Academy of Pediatrics. The writing group used these reviews to update its recommendations aimed at resuscitation of cardiac arrest following drowning in adults and children.

YouTube as a source of information in cardiopulmonary resuscitation for 2020 AHA Resuscitation Guidelines

Background

The Internet has transformed global information access, particularly through platforms like YouTube, which launched in 1995 and has since become the second largest search engine worldwide with over two billion monthly users. While YouTube offers extensive educational content, including health topics like cardiopulmonary resuscitation (CPR) and basic life support (BLS), it also poses risks due to potential misinformation. Our study focuses on evaluating the accuracy of CPR and BLS videos on YouTube according to the latest 2020 American Heart Association (AHA) guidelines. This research aims to highlight inconsistencies and provide insights into improving YouTube as a reliable educational resource for both lay rescuers and healthcare professionals.

Methods

In this cross-sectional observational study, English YouTube videos uploaded between October 21, 2020, and May 1, 2023, were searched using keywords related to CPR and basic life support. Videos were assessed for their source, duration, views, use of human or mannequin models, and mean assessment scores by two emergency medicine physicians. A third physician's opinion was sought in cases of disagreement. The first assessment evaluated video validity based on specified information criteria, while the second assessed their ability to convey advanced medical information aligned with the 2020 AHA guidelines.

Results

In this study, 201 English YouTube videos uploaded between October 21, 2020, and May 1, 2023, were evaluated based on search terms related to CPR and BLS, resulting in 95 videos meeting inclusion criteria after excluding 106 due to various reasons. Most included videos were from healthcare professionals (49.5%), followed by anonymous sources (29.5%) and official medical organizations (21.1%). Video durations ranged widely from 43 to 6,019 seconds, with an average of 692 seconds. Videos featuring mannequins predominated (91.6%), followed by those using human subjects (5.3%) or both (3.2%). Healthcare professional and official medical organization videos scoring significantly higher than those of unknown origin (p = 0.001). Video length did not correlate significantly with view counts, although shorter videos under 5 minutes tended to have higher average views.

Discussion

The results presented in this study demonstrated that English-language videos on YouTube related to BLS and CPR, throughout the study period, did not conform to the 2020 AHA guidelines in terms of providing basic information for lay rescuers. Furthermore, healthcare professionals cannot obtain advanced medical knowledge through these videos. We recommend a professional oversight mechanism in health-related videos that does not tolerate such misinformation.

External Validation and Comparison of Statistical and Machine Learning-Based Models in Predicting Outcomes Following Out-of-Hospital Cardiac Arrest: A Multicenter Retrospective Analysis

BACKGROUND

The aim of this study was to validate and compare the performance of statistical (Utstein-Based Return of Spontaneous Circulation and Shockable Rhythm-Witness-Age-pH) and machine learning-based (Prehospital Return of Spontaneous Circulation and Swedish Cardiac Arrest Risk Score) models in predicting the outcomes following out-of-hospital cardiac arrest and to assess the impact of the COVID-19 pandemic on the models' performance.

METHODS AND RESULTS

This retrospective analysis included adult patients with out-of-hospital cardiac arrest treated at 3 academic hospitals between 2015 and 2023. The primary outcome was neurological outcomes at hospital discharge. Patients were divided into pre- (2015-2019) and post-2020 (2020-2023) subgroups to examine the effect of the COVID-19 pandemic on out-of-hospital cardiac arrest outcome prediction. The models' performance was evaluated using the area under the receiver operating characteristic curve and compared by the DeLong test. The analysis included 2161 patients, 1241 (57.4%) of whom were resuscitated after 2020. The cohort had a median age of 69.2 years, and 1399 patients (64.7%) were men. Overall, 69 patients (3.2%) had neurologically intact survival. The area under the receiver operating characteristic curves for predicting neurological outcomes were 0.85 (95% CI, 0.83-0.87) for the Utstein-Based Return of Spontaneous Circulation score, 0.82 (95% CI, 0.81-0.84) for the Shockable Rhythm-Witness-Age-pH score, 0.79 (95% CI, 0.78-0.81) for the Prehospital Return of Spontaneous Circulation score, and 0.79 (95% CI, 0.77-0.81) for the Swedish Cardiac Arrest Risk Score model. The Utstein-Based Return of Spontaneous Circulation score significantly outperformed both the Prehospital Return of Spontaneous Circulation score (P<0.001) and the Swedish Cardiac Arrest Risk Score model (P=0.007). Subgroup analysis indicated no significant difference in predictive performance for patients resuscitated before versus after 2020.

CONCLUSIONS

In this external validation, both statistical and machine learning-based models demonstrated excellent and fair performance, respectively, in predicting neurological outcomes despite different model architectures. The predictive performance of all evaluated clinical scoring systems was not significantly influenced by the COVID-19 pandemic.

What Is the Opinion of the Health Care Personnel Regarding the Use of Different Assistive Tools to Improve the Quality of Neonatal Resuscitation?

OBJECTIVE

 It is important to determine whether the use of different quality improvement tools in neonatal resuscitation is well-received by health care teams and improves coordination and perceived quality of the stabilization of the newborn at birth. This study aimed to explore the satisfaction of personnel involved in resuscitation for infants under 32 weeks of gestational age (<32 wGA) at birth with the use of an assistance toolkit: Random Real-time Safety Audits (RRSA) of neonatal stabilization stations, the use of pre-resuscitation checklists, and the implementation of briefings and debriefings.

STUDY DESIGN

 A quasi-experimental, prospective, multicenter intervention study was conducted in five level III-A neonatal intensive care units in Madrid (Spain). The intervention involved conducting weekly RRSA of neonatal resuscitation stations and the systematic use of checklists, briefings, and debriefings during stabilization at birth for infants <32 wGA. The satisfaction with their use was analyzed through surveys conducted with the personnel responsible for resuscitating these newborns. These surveys were conducted both before and after the intervention phase (each lasting 1 year) and used a Likert scale response model to assess various aspects of the utility of the introduced assistance tools, team coordination, and perceived quality of the resuscitation.

RESULTS

 Comparison of data from 200 preintervention surveys and 155 postintervention surveys revealed statistically significant differences (p < 0.001) between the two phases. The postintervention phase scored higher in all aspects related to the effective utilization of these tools. Improvements were observed in team coordination and the perceived quality of neonatal resuscitation. These improved scores were consistent across personnel roles and years of experience.

CONCLUSION

 Personnel attending to infants <32 wGA in the delivery room are satisfied with the application of RRSA, checklists, briefings, and debriefings in the neonatal resuscitation and perceive a higher level of quality in the stabilization of these newborns following the introduction of these tools.

KEY POINTS

· RRSA, checklists, briefings, and debriefings improve the quality of neonatal resuscitation at birth.. · These tools, when used together, are well-received and enhance perceived resuscitation quality.. · Perception of utility and quality improvement is consistent across roles and experience..

Prognostic Impact of Heart Rhythm Shockability Trajectory in Out-of-Hospital Cardiac Arrest: A Multicenter Retrospective Study

BACKGROUND

This study aimed to investigate the association between the temporal transitions in heart rhythms during cardiopulmonary resuscitation (CPR) and outcomes after out-of-hospital cardiac arrest.

METHODS

This was an analysis of the prospectively collected databases in 3 academic hospitals in northern and central Taiwan. Adult patients with out-of-hospital cardiac arrest transported by emergency medical service between 2015 and 2022 were included. Favorable neurological recovery and survival to hospital discharge were the primary and secondary outcomes, respectively. Time-specific heart rhythm shockability was defined as the probability of shockable rhythms at a particular time point during CPR. The temporal changes in the time-specific heart rhythm shockability were calculated by group-based trajectory modeling. Multivariable logistic regression analyses were performed to examine the association between the trajectory group and outcomes. Subgroup analyses examined the effects of extracorporeal CPR in different trajectories.

RESULTS

The study comprised 2118 patients. The median patient age was 69.1 years, and 1376 (65.0%) patients were male. Three distinct trajectories were identified: high-shockability (52 patients; 2.5%), intermediate-shockability (262 patients; 12.4%), and low-shockability (1804 patients; 85.2%) trajectories. The median proportion of shockable rhythms over the course of CPR for the 3 trajectories was 81.7% (interquartile range, 73.2%-100.0%), 26.7% (interquartile range, 16.7%-37.5%), and 0% (interquartile range, 0%-0%), respectively. The multivariable analysis indicated both intermediate- and high-shockability trajectories were associated with favorable neurological recovery (intermediate-shockability: adjusted odds ratio [aOR], 4.98 [95% CI, 2.34-10.59]; high-shockability: aOR, 5.40 [95% CI, 2.03-14.32]) and survival (intermediate-shockability: aOR, 2.46 [95% CI, 1.44-4.18]; high-shockability: aOR, 2.76 [95% CI, 1.20-6.38]). The subgroup analysis further indicated extracorporeal CPR was significantly associated with favorable neurological outcomes (aOR, 4.06 [95% CI, 1.11-14.81]) only in the intermediate-shockability trajectory.

CONCLUSIONS

Heart rhythm shockability trajectories were associated with out-of-hospital cardiac arrest outcomes, which may be a supplementary factor in guiding the allocation of medical resources, such as extracorporeal CPR.

The effect of standalone audio-visual feedback devices on the quality of chest compressions during laypersons' cardiopulmonary resuscitation training: a systematic review and meta-analysis

AIMS

Individual studies that investigated the effect of standalone audio-visual feedback (AVF) devices during laypersons' cardiopulmonary resuscitation (CPR) training have yielded conflicting results. This review aimed to evaluate the effect of standalone AVF devices on the quality of chest compressions during laypersons' CPR training.

METHOD AND RESULT

Randomized controlled trials of simulation studies recruiting participants without actual patient CPR experience were included. The intervention evaluated was the quality of chest compressions with standalone AVF devices vs. without AVF devices. Databases, such as PubMed, Cochrane Central, Embase, Cumulative Index to Nursing & Allied Health Literature (CINAHL), Web of Science, and PsycINFO, were searched from January 2010 to January 2022. The risk of bias was assessed using the Cochrane risk of bias tool. A meta-analysis alongside a narrative synthesis was used for examining the effect of standalone AVF devices.Sixteen studies were selected for this systematic review. A meta-analysis revealed an increased compression depth of 2.22 mm [95% CI (Confidence Interval), 0.88-3.55, P = 0.001] when participants performed CPR using the feedback devices. Besides, AVF devices enabled laypersons to deliver compression rates closer to the recommended range of 100-120 per min. No improvement was noted in chest recoil and hand positioning when participants used standalone AVF devices.

CONCLUSION

The quality of the included studies was variable, and different standalone AVF devices were used. Standalone AVF devices were instrumental in guiding laypersons to deliver deeper compressions without compromising the quality of compression rates. However, the devices did not improve the quality of chest recoil and placement of the hands.

Is There Any Difference in the Quality of CPR Depending on the Physical Fitness of Firefighters?

(1) Background: The purposes of this study were to develop a physical fitness evaluation program for new firefighters, to investigate whether there is a quality difference in performing CPR for cardiac arrest patients according to physical strength, and to provide basic data to improve CPR quality. (2) Methods: The subjects of this study were fire trainees who were appointed as firefighters for the first time in G province from 3 March 2021 to 25 June 2021. The age of the subjects was 25-29 years old, and their experience of working as a firefighter was less than three months. According to the purposes of the study, the researcher composed the Physical Fitness Evaluation Program, including the physical fitness evaluation method and steps, and requested a content expert group to modify and supplement the 'physical fitness assessment program'. The subjects were divided into four groups according to their levels of physical strength, and CPR was performed for 50 min in groups of two. A high-end Resuscitation Anne Simulator (Laeadal, Norway) mannequin was used to evaluate the quality of CPR. (3) Results: When comparing the difference in CPR quality, there were statistically significant differences in the number of chest compressions and compression depth, but all groups met the CPR guidelines. In the case of this study, it is thought that high-quality CPR could be performed because the subjects' average age was low and they continued to exercise to improve their physical strength for their role. (4) Conclusions: It was concluded that the fitness level of new firefighters confirmed by this study was sufficient for general high-quality CPR. In addition, for high-quality CPR, continuous management is required by developing a continuous CPR education and physical training program for all firefighters.

Effectiveness of video self-instruction training on cardiopulmonary resuscitation retention of knowledge and skills among nurses in north-western Nigeria

Background

Adaptable cardiopulmonary resuscitation/basic life support (CPR/BLS) training are required to reduce cardiac arrest mortality globally, especially among nurses. Thus, this study aims to compared CPR knowledge and skills retention level between instructor-led (control group) and video self-instruction training (intervention group) among nurses in northwestern Nigeria.

Methods

A two-arm randomized controlled trial study using double blinding method was conducted with 150 nurses from two referral hospitals. Stratified simple random method was used to choose eligible nurses. For video self-instruction training (intervention group), participants learnt the CPR training via computer in a simulation lab for 7 days, in their own available time whereas for instructor-led training (control group), a 1-day program was conducted by AHA certified instructors. A generalized estimated equation model was used for statistical analysis.

Results

Generalized Estimated Equation showed that there were no significant differences between the intervention group (p = 0.055) and control group (p = 0.121) for both CPR knowledge and skills levels respectively, whereas higher probability of having good knowledge and skills in a post-test, one month and three-month follow-up compared to baseline respectively, adjusted with covariates (p < 0.05). Participants had a lower probability of having good skills at 6-month follow-up compared to baseline, adjusted with covariates (p = 0.003).

Conclusion

This study showed no significant differences between the two training methods, hence video self-instruction training is suggested can train more nurses in a less cost-effective manner to maximize resource utilization and quality nursing care. It is suggested to be used to improve knowledge and skills among nurses to ensure cardiac arrest patients receive excellent resuscitation care.

Development of an intervention to facilitate dissemination of community-based training to respond to out-of-hospital cardiac arrest: FirstCPR

Background and aim

Out-of-hospital cardiac arrest (OHCA) is a significant public health issue with low survival rates. Prompt bystander action can more than double survival odds. OHCA response training is primarily pursued due to work-related mandates, with few programs targeting communities with lower training levels. The aim of this research was to describe the development process of a targeted multicomponent intervention package designed to enhance confidence and training among laypeople in responding to an OHCA.

Methods

An iterative, three-phase program development process was employed using a mixed methods approach. The initial phase involved establishment of a multidisciplinary panel that informed decisions on key messages, program content, format, and delivery modes. These decisions were based on scientific evidence and guided by behavioural theories. The second phase comprised the development of the intervention package, identifying existing information and developing new material to fill identified gaps. The third phase involved refining and finalising the material via feedback from panel members, stakeholders, and community members.

Results

Through this approach, we collaboratively developed a comprehensive evidence-based education and training package consisting of a digital intervention supplemented with free access to in-person education and training. The package was designed to teach community members the specific steps in recognising and responding to a cardiac arrest, while addressing commonly known barriers and fears related to bystander response. The tailored program and delivery format addressed the needs of individuals of diverse ages, cultural backgrounds, and varied training needs and preferences.

Conclusion

The study highlights the importance of community engagement in intervention development and demonstrates the need of evidence-based and collaborative approaches in creating a comprehensive, localised, relatively low-cost intervention package to improve bystander response to OHCA.

Association between Trajectories of End-tidal Carbon Dioxide and Return of Spontaneous Circulation among Emergency Department Patients with Out-of-hospital Cardiac Arrest

BACKGROUND

We aimed to identify distinct trajectories of end-tidal carbon dioxide (EtCO₂) during cardiopulmonary resuscitation in patients with out-of-hospital cardiac arrest (OHCA) and to investigate the association between EtCO₂ trajectories and OHCA outcomes.

METHODS

This was a secondary analysis of a prospectively collected database on adult patients with OHCA who had been resuscitated in the emergency department of a tertiary medical center between 2015 and 2020. The primary outcome was the return of spontaneous circulation (ROSC). Group-based trajectory modelling was used to identify the EtCO₂ trajectories. Multivariable logistic regression analysis was performed to evaluate the association between EtCO₂ trajectories and ROSC. The predictive performance of the EtCO₂ trajectories was assessed using the area under the receiver operating characteristic curve (AUC).

RESULTS

The study comprised 655 patients with OHCA. In the primary analysis, three distinct EtCO₂ trajectories, including 10-mmHg, 30-mmHg, and 50-mmHg trajectories, were identified. Compared with the 10-mmHg trajectory, both 30-mmHg (odds ratio [OR]: 4.66, 95% confidence interval [CI]: 3.15-6.90) and 50-mmHg (OR: 7.58, 95% CI: 4.30-13.35) trajectories were associated with a higher likelihood of ROSC. In a sensitivity analysis of excluding EtCO₂ measured before tracheal intubation or after sodium bicarbonate administration, the predictive ability of the identified EtCO₂ trajectories remained. As a single predictor of ROSC, EtCO₂ trajectories had an acceptable discriminative performance (AUC: 0.69, 95% CI: 0.66-0.73).

CONCLUSION

Three distinct EtCO₂ trajectories during cardiopulmonary resuscitation were identified and significantly associated with outcomes. Early identification of these EtCO₂ trajectories could potentially guide the ongoing resuscitation efforts.

Understanding the Importance of the Lay Responder Experience in Out-of-Hospital Cardiac Arrest: A Scientific Statement From the American Heart Association

Bystander cardiopulmonary resuscitation (CPR) is critical to increasing survival from out-of-hospital cardiac arrest. However, the percentage of cases in which an individual receives bystander CPR is actually low, at only 35% to 40% globally. Preparing lay responders to recognize the signs of sudden cardiac arrest, call 9-1-1, and perform CPR in public and private locations is crucial to increasing survival from this public health problem. The objective of this scientific statement is to summarize the most recent published evidence about the lay responder experience of training, responding, and dealing with the residual impact of witnessing an out-of-hospital cardiac arrest. The scientific statement focuses on the experience-based literature of actual responders, which includes barriers to responding, experiences of doing CPR, use of an automated external defibrillator, the impact of dispatcher-assisted CPR, and the potential for postevent psychological sequelae. The large body of qualitative and observational studies identifies several gaps in crucial knowledge that, if targeted, could increase the likelihood that those who are trained in CPR will act. We suggest using the experience of actual responders to inform more contextualized training, including the implications of performing CPR on a family member, dispelling myths about harm, training and litigation, and recognition of the potential for psychologic sequelae after the event.

Why Bystanders Did Not Perform Cardiopulmonary Resuscitation on Out-of-Hospital Cardiac Arrest Patients: A Multi-Center Study in Hanoi (Vietnam)

AIM

The aim of this study was to determine why bystanders did not use formal Emergency Medical Services (EMS) or conduct cardiopulmonary resuscitation (CPR) on the scene for out-of-hospital cardiac arrest (OHCA) patients in Hanoi, Vietnam.

METHODS

This was a prospective, observational study of OHCA patients admitted to five tertiary hospitals in the Hanoi area from June 2018 through January 2019. The data were collected through interviews (using a structured questionnaire) with bystanders.

RESULTS

Of the 101 patients, 79% were aged <65 years, 71% were men, 79% were witnessed to collapse, 36% were transported to the hospital by formal EMS, and 16% received bystander CPR at the scene. The most frequently indicated reason for not using EMS by the attendants was "using a private vehicle or taxi is faster" (85%). The reasons bystanders did not conduct CPR at the scene included "not recognizing the ailment as cardiac arrest" (60%), "not knowing how to perform CPR" (33%), and "being afraid of doing harm to patients" (7%). Only seven percent of the bystanders had been trained in CPR.

CONCLUSION

The information revealed in this study provides useful information to indicate what to do to increase EMS use and CPR provision. Spreading awareness and training among community members regarding EMS roles, recognition of cardiac arrest, CPR skills, and dispatcher training to assist bystanders are crucial to improve the outcomes of OHCA patients in Vietnam.

Association Between Hospital Resuscitation Team Leader Credentials and Survival Outcomes for In-hospital Cardiac Arrest

OBJECTIVE

To assess whether survival rates for in-hospital cardiac arrest (IHCA) vary across hospitals depending on whether resuscitations are typically led by an attending physician, a physician trainee, or a nonphysician.

PATIENTS AND METHODS

In 2018, we conducted a survey of hospitals participating in the national Get with the Guidelines - Resuscitation registry for IHCA. Using responses from the question "Who typically leads codes at your institution?" we categorized hospitals on the basis of who typically leads their resuscitations: attending physician, physician trainee, or nonphysician. We then compared risk-adjusted hospital rates of return of spontaneous circulation, survival to discharge, and favorable neurological survival from 2015 to 2017 between these 3 hospital groups by using multivariable hierarchical regression.

RESULTS

Overall, 193 hospitals completed the study survey, representing a total of 44,477 IHCAs (mean age, 65.0±15.5 years; 40.8% were women). Most hospitals had resuscitations led by physicians, with 121 (62.7%) led by an attending physician, 58 (30.0%) by a physician trainee, and 14 (7.3%) by a nonphysician. The risk-standardized rates of survival to discharge were similar across hospitals, regardless of whether resuscitations were typically led by an attending physician, a physician trainee, or a nonphysician (25.6%±4.8%, 25.9%±4.7%, and 25.7%±3.6%, respectively; P=.88). Similarly, there were no differences between the 3 groups in risk-adjusted rates of return of spontaneous circulation (71.7%±6.3%, 73%±6.3%, and 73.4%±6.4%; P=.30) and favorable neurological survival (21.6%±7.1%, 22.7%±6.1%, and 20.9%±6.5%; P=.50).

CONCLUSION

In hospitals in a national IHCA registry, IHCA resuscitations were usually led by physicians. However, there was no association between a hospital's typical resuscitation team leader credentials and IHCA survival outcomes.

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

AIM

Automated 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.

METHODS

Articles 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.

RESULTS

The 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).

CONCLUSION

The 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.

Teaching Evidence-Based Sepsis Care: A Sepsis Escape Room

BACKGROUND

Using evidence-based sepsis guidelines, nurse educators identified the nursing skills required to recognize and treat sepsis.

METHOD

Nurse educators created an innovative, interactive sepsis escape room to provide sepsis education. The escape room included a manikin, puzzles, distractors, riddles, and props. Participants were given 20 minutes to solve four puzzles/riddles to treat the sepsis patient and escape the room.

RESULTS

All but two (N = 16) groups solved the clues and riddles to prioritize treatment in the allotted time. Evaluations were excellent. Mean score (1 = poor to 5 = outstanding) for overall escape room experience was 4.92. Adherence data improved on the Surviving Sepsis Campaign sepsis performance measure intervention bundles (SEP 1-3 care bundles) 2 months following the escape room. Bundles are a group of interventions that improve care.

CONCLUSION

The escape room engaged nurses in educational gaming, stimulating critical thinking and problem solving contributing to improved clinical outcomes. [J Contin Educ Nurs. 2021;52(5):217-225.].

The assessment of a manikin-based low-dose, high-frequency cardiac resuscitation quality improvement program in early UK adopter hospitals

BACKGROUND

Adult and paediatric basic life support (BLS) training are often conducted via group training with an accredited instructor every 24 months. Multiple studies have demonstrated a decline in the quality of cardio-pulmonary resuscitation (CPR) performed as soon as 3-month post-training. The 'Resuscitation Quality Improvement' (RQI) programme is a quarterly low-dose, high-frequency training, based around the use of manikins connected to a cart providing real-time and summative feedback. We aimed to evaluate the effects of the RQI Programme on CPR psychomotor skills in UK hospitals that had adopted this as a method of BLS training, and establish whether this program leads to increased compliance in CPR training.

METHODS

The study took place across three adopter sites and one control site. Participants completed a baseline assessment without live feedback. Following this, participants at the adopter sites followed the RQI curriculum for adult CPR, or adult and infant CPR. The curriculum was split into quarterly training blocks, and live feedback was given on technique during the training session via the RQI cart. After following the curriculum for 12/24 months, participants completed a second assessment without live feedback.

RESULTS

At the adopter sites, there was a significant improvement in the overall score between baseline and assessment for infant ventilations (N = 167, p < 0.001), adult ventilations (n = 129, p < 0.001), infant compressions (n = 163, p < 0.001) adult compressions (n = 205, p < 0.001), and adult CPR (n = 249, p < 0.001). There was no significant improvement in the overall score for infant CPR (n = 206, p = 0.08). Data from the control site demonstrated a statistically significant improvement in mean score for adult CPR (n = 22, p = 0.02), but not for adult compressions (N = 18, p = 0.39) or ventilations (n = 17, p = 0.08). No statistically significant difference in improvement of mean scores was found between the grouped adopter sites and the control site. The effect of the duration of the RQI curriculum on CPR performance appeared to be minimal in this data set. Compliance with the RQI curriculum varied by site, one site maintained hospital compliance at 90% over a 1 year period, however compliance reduced over time at all sites.

CONCLUSIONS

This data demonstrated an increased adherence with guidelines for high-quality CPR post-training with the RQI cart, for all adult and most infant measures, but not infant CPR. However, the relationship between a formalised quarterly RQI curriculum and improvements in resuscitation skills is not clear. It is also unclear whether the RQI approach is superior to the current classroom-based BLS training for CPR skill acquisition in the UK. Further research is required to establish how to optimally implement the RQI system in the UK and how to optimally improve hospital wide compliance with CPR training to improve the outcomes of in-hospital cardiac arrests.

A non-inferiority randomised controlled trial comparing self-instruction with instructor-led method in training of layperson cardiopulmonary resuscitation

Our study aimed to compare the effect of self-instruction with manikin feedback to that of instructor-led method on cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) skill performance. In our randomized non-inferiority trial, 64 non-healthcare providers were randomly allocated into self-instruction and instructor-led groups. Both groups watched a 27-min standardized teaching video. Participants in the self-instruction group then performed hands-on practice on the Resusci Anne QCPR with a device-driven feedback, while those in the instructor-led group practiced manikins; feedback was provided and student's questions were answered by instructors. Outcomes were measured by blinded evaluators and SkillReporter software. The primary outcome was the pass rate. Secondary outcomes were scores of the knowledge test and items of individual skill performance. The baseline characteristics of the two groups were similar. The pass rates were 93.8% in both group (absolute difference 0%, p = 0.049 for noninferiority). The knowledge test scores were not significantly different. However, the self-instruction group performed better in some chest compression and ventilation skills, but performed worse in confirming environmental safety and checking normal breathing. There was no difference in AED skills between the two groups. Our results showed the self-instruction method is not inferior to the instructor-led method.

Improving the Performance of Residents in Pediatric Resuscitation with Frequent Simulated Codes

Aim. Exposure to real codes during pediatric residency training is scarce. Consequently, experiencing mock codes scenarios can provide an opportunity to increase residents’ confidence and knowledge in managing pediatric emergencies. Hypothesis. Pediatric senior residents perform better as code team leaders if they are exposed to frequent mock codes. Material and Methods. Forty-three pediatric senior residents (postgraduate year [PGY] two and three) participated in the study. Team leader performance was assessed utilizing the Team Emergency Assessment Measure (TEAM) scoring. Residents’ team leadership performance was assessed before and 6 months after the implementation of weekly mock codes. Results. Pediatric residents’ team leadership performance in mock codes improved after exposure to weekly practice mock code sessions (71.93 ± 18.50 vs 81.44 ± 11.84, P = 0.01). Conclusion. Increasing the frequency of mock code sessions during residency training led to an improvement in code team leadership performance in pediatric senior residents.

Changes of knowledge and practical skills before and after retraining for basic life support: Focused on students of Dental School

Background: Considering the increasing possibility of emergency situations in dental clinics over time, we conducted this study to evaluate the changes in the knowledge and practical skills of students of dental school before and after retraining for 2 years after the initial education on basic life support (BLS) of the American Heart Association (AHA). Methods: All third-year students of dental school who had received the same education on BLS provider training of the AHA 2 years earlier were included in this study. Among them, 98 students were asked to answer a questionnaire about BLS knowledge and conduct a practical skills assessment of high-quality cardiopulmonary resuscitation using Little Anne QCPR before and after retraining. Results: After retraining, the level of BLS knowledge increased in all 7 categories, and BLS performance increased in all 19 subcategories. Comparison of the QCPR numerical data items before and after retraining showed that all items after retraining met the criteria recommended by the AHA. Conclusion: Students of dental school had low levels of knowledge and practical skills of BLS before retraining after 2 years from the initial education and had high levels after retraining. Therefore, BLS training must be updated periodically, and more effective education methods are required to maintain BLS knowledge and practical skills.

CPR Compression Rotation Every One Minute Versus Two Minutes: A Randomized Cross-Over Manikin Study

Background

The current basic life support guidelines recommend two-minute shifts for providing chest compressions when two rescuers are performing cardiopulmonary resuscitation. However, various studies have found that rescuer fatigue can occur within one minute, coupled with a decay in the quality of chest compressions. Our aim was to compare chest compression quality metrics and rescuer fatigue between alternating rescuers in performing one- and two-minute chest compressions.

Methods

This prospective randomized cross-over study was conducted at Songklanagarind Hospital, Hat Yai, Songkhla, Thailand. We enrolled sixth-year medical students and residents and randomly grouped them into pairs to perform 8 minutes of chest compression, utilizing both the one-minute and two-minute scenarios on a manikin. The primary end points were chest compression depth and rate. The secondary end points included rescuers' fatigue, respiratory rate, and heart rate.

Results

One hundred four participants were recruited. Compared with participants in the two-minute group, participants in the one-minute group had significantly higher mean (standard deviation, SD) compression depth (mm) (45.8 (7.2) vs. 44.5 (7.1), P=0.01) but there was no difference in the mean (SD) rate (compressions per min) (116.1 (12.5) vs. 117.8 (12.4), P=0.08), respectively. The rescuers in the one-minute group had significantly less fatigue (P < 0.001) and change in respiratory rate (P < 0.001), but there was no difference in the change of heart rate (P=0.59) between the two groups.

Conclusion

There were a significantly higher compression depth and lower rescuer fatigue in the 1-minute chest compression group compared with the 2-minute group. This trial is registered with TCTR20170823001.

Medical Student Skill Retention After Cardiopulmonary Resuscitation Training: A Cross-Sectional Simulation Study

INTRODUCTION

The retention of cardiopulmonary resuscitation skills and the ideal frequency of retraining remain unanswered. This study investigated the retention of cardiopulmonary resuscitation skills by medical students for up to 42 months after training.

METHODS

In a cross-sectional study, 205 medical students received 10 hours of training in basic life support in 3 practical classes, during their first semester at school. Then, they were divided into 4 groups, according to the time elapsed since the training: 73 after 1 month, 55 after 18 months, 41 after 30 months, and 36 after 42 months. Nineteen cardiopulmonary resuscitation skills and 8 potential technical errors were evaluated by mannequin-based simulation and reviewed using filming.

RESULTS

The mean retention of the skills was 90% after 1 month, 74% after 18 months, 62% after 30 months, and 61% after 42 months (P < 0.001). The depth of chest compressions had the greatest retention over time (87.8%), with no significant differences among groups. Compressions performed greater than 120 per minute were less likely to be done with adequate depth. Ventilation showed a progressive decrease in retention from 93% (n = 68) after 1 month to 19% (n = 7) after 42 months (P < 0.001). All 205 students were able to turn the automated external defibrillator on and deliver the shock.

CONCLUSIONS

The depth of chest compressions and the use of an automated external defibrillator were the skills with the highest retention over time. Based on a skills retention prediction curve, we suggest that 18 to 24 months as the minimum retraining interval to maintain at least 70% of skills.

[Introduction to debriefing for internists: how to transform real or simulated clinical situations into learning moments]

Debriefing is a phase of synthesis and reflection that immediately follows a real-life or simulated situation. It is an essential educational step that forces the learners to reflect upon the thought processes that underlie their actions. Debriefing encourages a personal and collective reflection in order to remodel erroneous mental schemas and rectify actions done in context. Debriefing cannot be improvised; it requires a sound structure and regular practice in order to be truly effective. The debriefer must be considerate, choose appropriate learning objectives and dedicate ample time to the learners. Debriefing is focused on learning acquired in context-in other words, on the actions that were performed within a real-life or simulated clinical practice situation-and immediately follows the situation. After an initial phase of emotional release, the debriefer will help learners analyse their actions to identify their underlying rationale (contextualization), extract the overarching principles related to the lived situation in order to modify the rationale if needed (decontextualization) and assist the transfer of learning to real life (in the case of simulation) and to similar situations (recontextualization). A final summary of learning achieved during the training session concludes the debriefing. Debriefing is useful in any learning situation, including in internal medicine. Even if simulation is still underused in internal medicine, post-event debriefing can be implanted in our clinical services. Indeed, training our students and shaping them into healthcare professionals rest in no small part on hospital rotations where the intern is confronted with real-patient situations that are suitable to learning. Some in-hospital clinical encounters can be actively transformed into learning opportunities thanks to post-event debriefing, but can also passively morph into bad daily practice if no supporting action is implemented. Debriefing can thus provide an opportunity to develop non-technical skills in critical situations, or doctor-patient communication skills, within a team or between colleagues. These competencies are the hallmark of well-trained interns and are indispensable for the proper functioning of a care team. We will not develop the emotional and psychological management of debriefing in this article. We hope we will helpfully introduce as many of our colleagues as possible to the art of debriefing in most circumstances.

An Evaluation of a New Debriefing Framework: REFLECT

BACKGROUND

Postresuscitation debriefing (PRD) is recommended by the American Heart Association guidelines but is infrequently performed. Prior studies have identified barriers for pediatric emergency medicine (PEM) fellows including lack of a standardized curriculum.

OBJECTIVE

Our objective was to create and assess the feasibility of a time-limited, structured PRD framework entitled REFLECT: Review the event, Encourage team participation, Focused feedback, Listen to each other, Emphasize key points, Communicate clearly, and Transform the future.

METHODS

Each PEM fellow (n = 9) at a single center was a team leader of a pre-intervention and post-intervention videotaped, simulated resuscitation followed by a facilitated team PRD. Our intervention was a 2-hour interactive, educational workshop on debriefing and the use of the REFLECT debriefing aid. Videos of the pre-intervention and post-intervention debriefings were blindly analyzed by video reviewers to assess for the presence of debriefing characteristics contained in the REFLECT debriefing aid. PEM fellow and team member assessments of the debriefings were completed after each pre-intervention and post-intervention simulation, and written evaluations by PEM fellows and team members were analyzed.

RESULTS

All 9 PEM fellows completed the study. There was an improvement in the pre-intervention and post-intervention assessment of the REFLECT debriefing characteristics as determined by fellow perception (63% to 83%, P < 0.01) and team member perception (63% to 82%, P < 0.001). All debriefings lasted less than 5 minutes. There was no statistical difference between pre-intervention and post-intervention debriefing time (P = 1.00).

CONCLUSIONS

REFLECT is a feasible debriefing aid designed to incorporate evidence-based characteristics into a PRD.

Improving the position of resuscitation team leader with simulation (IMPORTS); a pilot cross-sectional randomized intervention study

BACKGROUND

Leadership and teamwork are important contributory factors in determining cardiac resuscitation performance and clinical outcome. We aimed to determine whether fixed positioning of the resuscitation team leader (RTL) relative to the patient influences leadership qualities during cardiac resuscitation using simulation.

METHODS

A cross-sectional randomized intervention study over 12 months' duration was conducted in university hospital simulation lab. ACLS-certified medical doctors were assigned to run 2 standardized simulated resuscitation code as RTL from a head-end position (HEP) and leg-end position (LEP). They were evaluated on leadership qualities including situational attentiveness (SA), errors detection (ED), and decision making (DM) using a standardized validated resuscitation-code-checklist (RCC). Performance was assessed live by 2 independent raters and was simultaneously recorded. RTL self-perceived performance was compared to measured performance.

RESULTS

Thirty-four participants completed the study. Mean marks for SA were 3.74 (SD ± 0.96) at HEP and 3.54 (SD ± 0.92) at LEP, P = .48. Mean marks for ED were 2.43 (SD ± 1.24) at HEP and 2.21 (SD ± 1.14) at LEP, P = .40. Mean marks for DM were 4.53 (SD ± 0.98) at HEP and 4.47 (SD ± 0.73) at LEP, P = .70. The mean total marks were 10.69 (SD ± 1.82) versus 10.22 (SD ± 1.93) at HEP and LEP respectively, P = .29 which shows no significance difference in all parameters. Twenty-four participants (71%) preferred LEP for the following reasons, better visualization (75% of participants); more room for movement (12.5% of participants); and better communication (12.5% of participants). RTL's perceived performance did not correlate with actual performance CONCLUSION:: The physical position either HEP or LEP appears to have no influence on performance of RTL in simulated cardiac resuscitation. RTL should be aware of the advantages and limitations of each position.

Nursing roles for in-hospital cardiac arrest response: higher versus lower performing hospitals

BACKGROUND

Good outcomes for in-hospital cardiac arrest (IHCA) depend on a skilled resuscitation team, prompt initiation of high-quality cardiopulmonary resuscitation and defibrillation, and organisational structures to support IHCA response. We examined the role of nurses in resuscitation, contrasting higher versus lower performing hospitals in IHCA survival.

METHODS

We conducted a descriptive qualitative study at nine hospitals in the American Heart Association's Get With The Guidelines-Resuscitation registry, purposefully sampling hospitals that varied in geography, academic status, and risk-standardised IHCA survival. We conducted 158 semistructured interviews with nurses, physicians, respiratory therapists, pharmacists, quality improvement staff, and administrators. Qualitative thematic text analysis followed by type-building text analysis identified distinct nursing roles in IHCA care and support for roles.

RESULTS

Nurses played three major roles in IHCA response: bedside first responder, resuscitation team member, and clinical or administrative leader. We found distinctions between higher and lower performing hospitals in support for nurses. Higher performing hospitals emphasised training and competency of nurses at all levels; provided organisational flexibility and responsiveness with nursing roles; and empowered nurses to operate at a higher scope of clinical practice (eg, bedside defibrillation). Higher performing hospitals promoted nurses as leaders-administrators supporting nurses in resuscitation care at the institution, resuscitation team leaders during resuscitation and clinical champions for resuscitation care. Lower performing hospitals had more restrictive nurse roles with less emphasis on systematically identifying improvement needs.

CONCLUSION

Hospitals that excelled in IHCA survival emphasised mentoring and empowering front-line nurses and ensured clinical competency and adequate nursing training for IHCA care. Though not proof of causation, nurses appear to be critical to effective IHCA response, and how to support their role to optimise outcomes warrants further investigation.

Implementation of a Low-Dose, High-Frequency Cardiac Resuscitation Quality Improvement Program in a Community Hospital

BACKGROUND

In 2015 the American Heart Association launched the Resuscitation Quality Improvement^Ⓡ (RQI^Ⓡ) Program to address the urgent need to improve in-hospital cardiac arrest survival through a novel competency-based model for health care provider (HCP) cardiopulmonary resuscitation (CPR) training. This innovation differs from the traditional Basic Life Support (BLS) training model by providing self-directed, low-dose, high-frequency CPR skill activities with the objectives of skills mastery and retention. A program implementation study was conducted at the first hospital in the state of Illinois to adopt RQI in 2016.

METHODS

The study was designed to evaluate implementation of the RQI program, CPR performance during RQI simulation sessions, and participant impressions at a community hospital. Quantitative data were evaluated based on psychomotor compression and ventilation performance. Quantitative and qualitative data were evaluated based on a perceptual CPR confidence and program satisfaction survey.

RESULTS

Statistical analysis demonstrates significant improvement in HCPs' quarterly psychomotor CPR skill performance over a one-year period in first compression score, and first and highest ventilation score per quarterly session. The number of attempts to pass the ventilation skill session decreased between the first and fourth quarter. Survey results of HCPs' program perceptions 30 months post-RQI implementation indicate satisfaction with the RQI program and an increase in CPR skill confidence.

CONCLUSION

Findings demonstrate that the RQI program for ongoing verification of BLS skill and knowledge provides improvements in HCPs' CPR psychomotor competence and confidence/satisfaction using an efficient and sustainable method at a community hospital.

Resuscitation Education Science: Educational Strategies to Improve Outcomes From Cardiac Arrest: A Scientific Statement From the American Heart Association

The formula for survival in resuscitation describes educational efficiency and local implementation as key determinants in survival after cardiac arrest. Current educational offerings in the form of standardized online and face-to-face courses are falling short, with providers demonstrating a decay of skills over time. This translates to suboptimal clinical care and poor survival outcomes from cardiac arrest. In many institutions, guidelines taught in courses are not thoughtfully implemented in the clinical environment. A current synthesis of the evidence supporting best educational and knowledge translation strategies in resuscitation is lacking. In this American Heart Association scientific statement, we provide a review of the literature describing key elements of educational efficiency and local implementation, including mastery learning and deliberate practice, spaced practice, contextual learning, feedback and debriefing, assessment, innovative educational strategies, faculty development, and knowledge translation and implementation. For each topic, we provide suggestions for improving provider performance that may ultimately optimize patient outcomes from cardiac arrest.

Knowledge acquisition and retention following Saving Children's Lives course for healthcare providers in Botswana: a longitudinal cohort study

OBJECTIVES

Millions of children die every year from serious childhood illnesses. Most deaths are avertable with access to quality care. Saving Children's Lives (SCL) includes an abbreviated high-intensity training (SCL-aHIT) for providers who treat serious childhood illnesses. The objective of this study was to examine the impact of SCL-aHIT on knowledge acquisition and retention of providers.

SETTING

76 participating centres who provide primary and secondary care in Kweneng District, Botswana.

PARTICIPANTS

Doctors and nurses expected by the District Health Management Team to provide initial care to seriously ill children, completed SCL-aHIT between January 2014 and December 2016, submitted demographic data, course characteristics and at least one knowledge assessment.

METHODS

Retrospective, cohort study. Planned and actual primary outcome was adjusted acquisition (change in total knowledge score immediately after training) and retention (change in score at 1, 3 and 6 months), secondary outcomes were pneumonia and dehydration subscores. Descriptive statistics and linear mixed models with random intercept and slope were conducted. Relevant institutional review boards approved this study.

RESULTS

211 providers had data for analysis. Cohort was 91% nurses, 61% clinic/health postbased and 45% pretrained in Integrated Management of Childhood Illness (IMCI). A strong effect of SCL-aHIT was seen with knowledge acquisition (+24.56±1.94, p<0.0001), and loss of retention was observed (-1.60±0.67/month, p=0.018). IMCI training demonstrated no significant effect on acquisition (+3.58±2.84, p=0.211 or retention (+0.20±0.91/month, p=0.824) of knowledge. On average, nurses scored lower than physicians (-19.39±3.30, p<0.0001). Lost to follow-up had a significant impact on knowledge retention (-3.03±0.88/month, p=0.0007).

CONCLUSIONS

aHIT for care of the seriously ill child significantly increased provider knowledge and loss of knowledge occurred over time. IMCI training did not significantly impact overall knowledge acquisition nor retention, while professional status impacted overall score and lost to follow-up impacted retention.

Feasibility and preliminary validity evidence for remote video-based assessment of clinicians in a global health setting

BACKGROUND

Serious childhood illnesses (SCI), defined as severe pneumonia, severe dehydration, sepsis, and severe malaria, remain major contributors to amenable child mortality worldwide. Inadequate recognition and treatment of SCI are factors that impact child mortality in Botswana. Skills assessments of providers caring for SCI have not been validated in low and middle-income countries.

OBJECTIVE

To establish preliminary inter-rater reliability, validity evidence, and feasibility for an assessment of providers who care for SCI using simulated patients and remote video capture in community clinic settings in Botswana.

METHODS

This was a pilot study. Four scenarios were developed via a modified Delphi technique and implemented at primary care clinics in Kweneng, Botswana. Sessions were video captured and independently reviewed. Response process and internal structure analysis utilized intra-class correlation (ICC) and Fleiss' Kappa. A structured log was utilized for feasibility of remote video capture.

RESULTS

Eleven subjects participated. Scenarios of Lower Airway Obstruction (ICC = 0.925, 95%CI 0.695-0.998) and Hypovolemic Shock from Severe Dehydration (ICC = 0.892, 95%CI 0.596-0.997) produced excellent ICC among raters while Lower Respiratory Tract Infection (LRTI, ICC = 0, 95%CI -0.034-0.97) and LRTI + Distributive Shock from Sepsis (0.365, 95%CI -0.025-0.967) were poor. Oxygen therapy (0.707), arranging transport (0.706), and fluid administration (0.701) demonstrated substantial task reliability.

CONCLUSIONS

Initial development of an assessment tool demonstrates many, but not all, criteria for validity evidence. Some scenarios and tasks demonstrate excellent reliability among raters, but others may be limited by manikin design and study implementation. Remote simulation assessment of some skills by clinic-based providers in global health settings is reliable and feasible.

Laborious but Elaborate: The Benefits of Really Studying Team Dynamics

In this manuscript we discuss the consequences of methodological choices when studying team processes "in the wild." We chose teams in healthcare as the application because teamwork cannot only save lives but the processes constituting effective teamwork in healthcare are prototypical for teamwork as they range from decision-making (e.g., in multidisciplinary decision-making boards in cancer care) to leadership and coordination (e.g., in fast-paced, acute-care settings in trauma, surgery and anesthesia) to reflection and learning (e.g., in post-event clinical debriefings). We draw upon recently emphasized critique that much empirical team research has focused on describing team states rather than investigating how team processes dynamically unfurl over time and how these dynamics predict team outcomes. This focus on statics instead of dynamics limits the gain of applicable knowledge on team functioning in organizations. We first describe three examples from healthcare that reflect the importance, scope, and challenges of teamwork: multidisciplinary decision-making boards, fast-paced, acute care settings, and post-event clinical team debriefings. Second, we put the methodological approaches of how teamwork in these representative examples has mostly been studied centerstage (i.e., using mainly surveys, database reviews, and rating tools) and highlight how the resulting findings provide only limited insights into the actual team processes and the quality thereof, leaving little room for identifying and targeting success factors. Third, we discuss how methodical approaches that take dynamics into account (i.e., event- and time-based behavior observation and micro-level coding, social sensor-based measurement) would contribute to the science of teams by providing actionable knowledge about interaction processes of successful teamwork.

The presence of psychological trauma symptoms in resuscitation providers and an exploration of debriefing practices

INTRODUCTION

Witnessing traumatic experiences can cause post-traumatic stress disorder (PTSD). The true impact on healthcare staff of attending in-hospital cardiac arrests (IHCAs) has not been studied. This cross-sectional study examined cardiac arrest debriefing practices and the burden of attending IHCAs on nursing and medical staff.

METHODS

A 33-item questionnaire-survey was sent to 517 doctors (of all grades), nurses and health-care assistants (HCAs) working in the emergency department, the acute medical unit and the intensive care unit of a district general hospital between April and August 2018. There were three sections: demographics; cardiac arrest and debriefing practices; trauma-screening questionnaire (TSQ).

RESULTS

The response rate was 414/517 (80.1%); 312/414 (75.4%) were involved with IHCAs. Out of 1463 arrests, 258 (17.6%) were debriefed. Twenty-nine of 302 (9.6%) staff screened positively for PTSD. Healthcare assistants and Foundation Year 1 doctors had higher TSQ scores than nurses or more senior doctors (p = 0.02, p = 0.02, respectively). Debriefing was not associated with PTSD risk (p = 0.98). Only 8/67 (11.9%) of resuscitation leaders had prior debriefing training.

CONCLUSIONS

Nearly 10% of acute care staff screened positively for PTSD as a result of attending an IHCA, with junior staff being most at risk of developing trauma symptoms. Very few debriefs occurred, possibly because of a lack of debrief training amongst cardiac arrest team leaders. More support is required for acute care nursing and medical staff following an IHCA.

A randomized education trial of spaced versus massed instruction to improve acquisition and retention of paediatric resuscitation skills in emergency medical service (EMS) providers

AIM

Resuscitation courses are typically taught in a massed format despite existing evidence suggesting skill decay as soon as 3 months after training. Our study explored the impact of spaced versus massed instruction on acquisition and long-term retention of provider paediatric resuscitation skills.

METHODS

Providers were randomized to receive a paediatric resuscitation course in either a spaced (four weekly sessions) or massed format (two sequential days). Infant and adult chest compressions [CC], bag mask ventilation [BMV], and intraosseous insertion [IO] performance was measured using global rating scales.

RESULTS

Forty-eight participants completed the study protocol. Skill performance improved from baseline in both groups immediately following training. 3-months post-training the infant and adult CC scores remained significantly improved from baseline testing in both the massed and spaced groups; however, the infant BMV and IO scores remained significantly improved from baseline testing in the spaced: BMV (pre, 1.8 ± 0.7 vs post-3-months, 2.2 ± 7; P = 0.005) IO (pre, 2.5 ± 1 vs post-3-months, 3.1 ± 0.5; P = 0.04) but not in the massed groups: BMV (pre, 1.6 ± 0.5 vs post-3-months, 1.8 ± 0.5; P = 0.98) IO (pre, 2.6 ± 1.1 vs post-3-months, 2.7 ± 0.2; P = 0.98).

CONCLUSION

3-month retention of CC skills are similar regardless of training format; however, retention of other resuscitation skills may be better when taught in a spaced format.

N95 filtering facepiece respirators do not reliably afford respiratory protection during chest compression: A simulation study

Background

N95 filtering facepiece respirators (N95 respirators) may not provide adequate protection against respiratory infections during chest compression due to inappropriate fitting.

Methods

This was a single-center simulation study performed from December 1, 2016, to December 31, 2016. Each participant underwent quantitative fit test (QNFT) of N95 respirators according to the Occupational Safety and Health Administration protocol. Adequacy of respirator fit was represented by the fit factor (FF), which is calculated as the number of ambient particles divided by the number inside the respirator. We divided all participants into the group that passed the overall fit test but failed at least one individual exercise (partially passed group [PPG]) and the group that passed all exercises (all passed group [APG]). Then, the participants performed three sessions of continuous chest compressions, each with a duration of 2 min, while undergoing real-time fit testing. The primary outcome was any failure (FF < 100) of the fit test during the three bouts of chest compression.

Results

Forty-four participants passed the QNFT. Overall, 73% (n = 32) of the participants failed at least one of the three sessions of chest compression; the number of participants who failed was significantly higher in the PPG than in the APG (94% vs. 61%; p = 0.02). Approximately 18% (n = 8) of the participants experienced mask fit failures, such as strap slipping.

Conclusions

Even if the participants passed the QNFT, the N95 respirator did not provide adequate protection against respiratory infections during chest compression.

Transcutaneous cardiac pacing competency among junior residents undergoing an ACLS course: impact of a modified high fidelity manikin

BACKGROUND

Transcutaneous cardiac pacing (TCP) is recommended to treat unstable bradycardia. Simulation might improve familiarity with this low-frequency procedure. Current mannequins fail to reproduce key features of TCP, limiting their usefulness. The objective of this study was to measure the impact of a modified high-fidelity mannequin on the ability of junior residents to achieve six critical tasks for successful TCP.

METHODS

First-year residents from various postgraduate programs taking an advanced cardiovascular life support (ACLS) course were enrolled two consecutive years (2015 and 2016). Both cohorts received the same standardized course content. An ALS simulator® mannequin was used to demonstrate and practice TCP during the bradycardia workshop of the first cohort (control cohort, 2015) and a modified high-fidelity mannequin that reproduces key features of TCP was used for the second cohort (intervention cohort, 2016). Participants were tested after training with a simulation scenario requiring TCP. Performances were graded based on six critical tasks. The primary outcome was the successful use of TCP, defined as having completed all tasks.

RESULTS

Eighteen participants in the intervention cohort completed all tasks during the simulation scenario compared to none in the control cohort (36 vs 0%, p < 0.001). Participants in the intervention cohort were more likely to recognize when pacing was inefficient (86 vs 12%), obtain ventricular capture (48 vs 2%), and check for a pulse rate to confirm capture (48 vs 0%).

CONCLUSIONS

TCP is a difficult skill to master for junior residents. Training using a modified high-fidelity mannequin significantly improved their ability to establish TCP during a simulation scenario.

Clinical instructors' perceptions of virtual reality in health professionals' cardiopulmonary resuscitation education

Objectives:

Cardiopulmonary resuscitation (CPR) is lifesaving. Yet, cardiac arrest survival remains low despite CPR intervention. Education has been highlighted as a strategy to overcome this issue. Virtual Reality technology has been gaining momentum in the field of clinical education. Published studies report benefits of virtual reality for CPR education; yet, perceptions of CPR instructors towards virtual reality remain unexplored. CPR instructors are key stakeholders in CPR education and their perceptions are valuable for the design and adoption of virtual reality-enhanced learning. The purpose of this study is therefore to understand the perceptions of CPR instructors towards using virtual reality for health professionals’ CPR education. The aim was addressed via three research questions: (1) What are the perceptions of CPR instructors towards current health professionals’ CPR education? (2) What are the perceptions of CPR instructors towards features of virtual reality ideal for health professionals’ CPR education? (3) What are the perceptions of CPR instructors towards the potential role of virtual reality in health professionals’ CPR education?

Methods:

A total of 30 CPR instructors were surveyed on their views towards current health professionals’ CPR education and the use of virtual reality for health professionals’ CPR education, before and after interacting with a CPR virtual reality simulation. Responses were analysed using interpretative thematic analysis.

Results:

CPR instructors perceived current health professionals’ CPR education as limited due to unideal test preparation (resources, practice, motivation, and frame of mind) and performance. They perceived fidelity, engagement, resource conservation, and memory enhancement as features of virtual reality ideal for health professionals’ CPR education. Virtual reality was viewed by CPR instructors as having potential as a blended learning tool, targeting both ‘novice’ and ‘experienced’ health professionals.

Conclusion:

The study highlighted the gaps in current health professionals’ CPR education that can be addressed using virtual-reality-enabled learning. Future research could investigate virtual reality simulations with features desirable for CPR education of target populations.

Effects of designated leadership and team-size on cardiopulmonary resuscitation: The Basel-Washington SIMulation (BaWaSim) trial

OBJECTIVE

During cardiopulmonary resuscitation (CPR), it remains unclear whether designating an individual person as team leader compared with emergent leadership results in better team performance. Also, the effect of CPR team size on team performance remains understudied.

METHODS

This randomized-controlled trial compared designated versus emergent leadership and size of rescue team (3 vs 6 rescuers) on resuscitation performance.

RESULTS

We included 90 teams with a total of 408 students. No difference in mean (±SD) hands-on time (seconds) were observed between emergent leadership (106 ± 30) compared to designated leadership (103 ± 27) groups (adjusted difference - 2.97 (95%CI -15.75 to 9.80, p = 0.645), or between smaller (103 ± 30) and larger teams (106 ± 26, adjusted difference 3.53, 95%CI -8.47 to 15.53, p = 0.56). Emergent leadership groups had a shorter time to circulation check and first defibrillation, but the quality of CPR based on arm and shoulder position was lower. No differences in CPR quality measures were observed between smaller and larger teams.

CONCLUSIONS

Within this international US/Swiss trial, leadership designation and larger team size did not improve hands-on time, but emergent leadership teams initiated defibrillation earlier. Improvements in performance may be more likely to be achieved by optimization of emergent leadership than increasing the size of cardiac arrest teams.

Team-based model for non-operating room airway management: validation using a simulation-based study

BACKGROUND

Non-operating room (non-OR) airway management has previously been identified as an area of concern because it carries a significant risk for complications. One reason for this could be attributed to the independent practice of residents in these situations. The aim of the present study was to ascertain whether differences in performance exist between residents working alone vs with a resident partner when encountering simulated non-OR airway management scenarios.

METHODS

Thirty-six anaesthesia residents were randomized into two groups. Each group experienced three separate scenarios (two scenarios initially and then a third 6 weeks later). The scenarios consisted of one control scenario and two critical event scenarios [i.e. asystole during laryngoscopy and pulseless electrical activity (PEA) upon post-intubation institution of positive pressure ventilation]. One group experienced the simulated non-OR scenarios alone (Solo group). The other group consisted of resident pairs, participating in the same three scenarios (Team group).

RESULTS

Although the time to intubation did not differ between the Solo and Team groups, there were several differences in performance. The Team group received better overall performance ratings for the asystole (8.5 vs 5.5 out of 10; P<0.001) and PEA (8.5 vs 5.8 out of 10; P<0.001) scenarios. The Team group was also able to recognize asystole and PEA conditions faster than the Solo group [10.1 vs 23.5 s (P<0.001) and 13.3 vs 36.0 s (P<0.001), respectively].

CONCLUSIONS

Residents who performed a simulated intubation with a second trained provider had better overall performance than those who practised independently. The residents who practised in a group were also faster to diagnose serious complications, including peri-intubation asystole and PEA. Given these data, it is reasonable that training programmes consider performing all non-OR airway management with a team-based method.
