Basic life support training using shared mental models improves team performance of first responders on normal wards: A randomised controlled simulation trial

Exploring cardiac arrest in 'at-home' settings: Concepts derived from a qualitative interview study with layperson bystanders

BACKGROUND

Two thirds of Out-of-Hospital Cardiac Arrests (OHCAs) occur at the patient's home ('at-home-CA'), where bystander CPR (B-CPR) rates are significantly lower than in public locations. Knowledge about the circumstances of this specific setting has mainly been limited to quantitative data. To develop a more conceptual understanding of the circumstances and dynamics of 'at-home CA', we conducted a qualitative interview study.

METHODS

Twenty-one semi-structured in-depth interviews were performed with laypersons who had witnessed 'at-home CA'. The interviews were audio recorded, transcribed, and analysed by qualitative content analysis (QCA). A category system was developed to classify facilitating and impeding factors and to finally derive overarching concepts of 'at-home CA'.

RESULTS

Qualitative Content Analysis yielded 1'347 relevant interview segments. Of these, 398 related to factors facilitating B-CPR, 328 to factors impeding, and 621 were classified neutral. Some of these factors were specific to 'at-home CA'. The privacy context was found to be a particularly supportive factor, as it enhanced the commitment to act and facilitated the detection of symptoms. Impeding factors, aggravated in 'at-home CA' settings, included limited support from other bystanders, acute stress response and impaired situational judgement, as well as physical challenges when positioning the patient. We derived six overarching concepts defining the 'at-home CA' situation: (a) unexpectedness of the event, (b) acute stress response, (c) situational judgement, (d) awareness of the necessity to perform B-CPR, (e) initial position of the patient, (f) automaticity of actions.

CONCLUSION

Integrating these concepts into dispatch protocols and layperson training may improve dispatcher-bystander interaction and the outcomes of 'at-home CA'.

Team situational awareness in the context of hospital emergency: A concept analysis

BACKGROUND

Successful management of in-hospital life threatening and emergency conditions require a well working, collaborative team. One of the vital skills that enhance team coordination of information and actions is team situational awareness (TSA). Although the concept of TSA has been long known in military and aviation settings, the concept has not been well investigated in the hospital emergency context.

OBJECTIVE

This analysis was to explore the concept of "TSA" in the context of hospital emergency to explain its meaning for optimum understanding and use in clinical practice and future research.

RESULTS

TSA encompasses two types of situational awareness, each equally important: complementary (individual) and shared situational awareness (SA). The three defining attributes of complementary SA are the perception, comprehension, and projection, meanwhile, the three defining attributes of shared SA include: (1) information is clearly shared; (2) interpreted in the same way; and (3) the same projection of actions formed to guide expectation. Although, TSA is related to other terms in literature, there is increasing acknowledgment that the concept has an impact on team performance. Finally, the two types of TSA should be considered when assessing team performance CONCLUSION: TSA is acknowledged in different fields requiring human control as a significant construct for team performance. Yet it needs to be examined in the emergency hospital context, systematically investigated and agreeably recognized as a fundamental factor in team performance.

Cardiopulmonary Resuscitation Training for Healthcare Professionals: A Scoping Review

SUMMARY STATEMENT

The optimal strategy for training cardiopulmonary resuscitation (CPR) for healthcare professionals remains to be determined. This scoping review aimed to describe the emerging evidence for CPR training for healthcare professionals.We screened 7605 abstracts and included 110 studies in this scoping review on CPR training for healthcare professionals. We assessed the included articles for evidence for the following topics: training duration, retraining intervals, e-learning, virtual reality/augmented reality/gamified learning, instructor-learner ratio, equipment and manikins, other aspects of contextual learning content, feedback devices, and feedback/debriefing. We found emerging evidence supporting the use of low-dose, high-frequency training with e-learning to achieve knowledge, feedback devices to perform high-quality chest compressions, and in situ team simulations with debriefings to improve the performance of provider teams.

Relationship between psychological characteristics, personality traits, and training on performance in a neonatal resuscitation scenario: A machine learning based analysis

BACKGROUND

In life-threatening emergency events, prompt decision-making and accurate reactions are essential for saving a human's life. Some of these skills can be improved by regular simulation trainings. However, besides these factors, individual characteristics may play a significant role in the patients' outcome after a resuscitation event. This study aimed to differentiate personality characteristics of team members who take responsibility for their actions, contextualizing the effect of training on resuscitation performance.

METHODS

Six hundred and two third-year medical students were asked to answer psychological and personality questionnaires. Fifty-five of them performed in a neonatal simulation resuscitation scenario. To assess participants' performances in the NLS scenario, we used a scenario-based designed NLS checklist. A machine learning design was utilized to better understand the interaction of psychological characteristics and training. The first model aimed to understand how to differentiate between people who take responsibility for their actions vs. those who do not. In a second model, the goal was to understand the relevance of training by contextualizing the effect of training to other important psychological and personality characteristics like locus of control, anxiety, emotion regulation, openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism.

RESULTS

No statistically significant differences were found for psychological characteristics between the training group and the no training group. However, as expected, differences were noted in favor of the training group for performance and within gender for psychological characteristics. When correcting for all these information in a model, anxiety and gender were the most important factors associated with taking responsibility for an action, while training was the only relevant factor in explaining performance during a neonatal resuscitation scenario.

CONCLUSION

Training had a significantly stronger effect on performance in medical students in a neonatal resuscitation scenario than individual characteristics such as demographics, personality, and trait anxiety.

Flipped learning enhances non-technical skill performance in simulation-based education: a randomised controlled trial

BACKGROUND

Many efforts of the past years aimed to build a safer health care system and hereby, non-technical skills (NTS) have been recognised to be responsible for over 70 % of preventable medical mishaps. In order to counteract those mishaps, several simulation-based trainings have been implemented in health care education to convey NTS. Still, the best and effective way to foster NTS in simulation-based training is not known. Due to the importance of NTS, this gap in knowledge needs to be filled. A possible approach to convey NTS effectively during simulation-based medical education (SBME), might be the use of the flipped learning approach. The benefits of flipped learning regarding the improvement of human factors (NTS), have not been investigated yet. Therefore, the authors introduced flipped learning as an experimental intervention into their SBME emergency trainings and aimed to analyse, whether flipped learning improved students´ NTS performance compared to lecture-based learning (LBL).

METHODS

In a randomized controlled trial, 3rd year medical students participated in a SBME training and then received either a further SBME training with integrated flipped learning on NTS (intervention), or a further SBME training and an accompanying lecture on NTS (control). NTS performance was assessed on three skill dimensions with a validated behavioural marker system.

RESULTS

The authors analysed NTS performance of 102 students, prior and after their allocation to each teaching method. The baseline NTS performance of both groups did not differ, whereas the intervention group enhanced significantly on all three skill dimensions (t (44) = 5.63, p < .001; t (44) = 4.47, p < .001; t (44) = 4.94, p < .001).

CONCLUSION

The integration of flipped learning into SBME yields a significant improvement of NTS performance and therefore medical educators should consider the application of flipped learning to convey complex human factors and skills.

Cardiac arrest: An interdisciplinary scoping review of the literature from 2019

Objectives

The Interdisciplinary Cardiac Arrest Research Review (ICARE) group was formed in 2018 to conduct a systematic annual search of peer-reviewed literature relevant to cardiac arrest. Now in its second year, the goals of the review are to illustrate best practices in research and help reduce compartmentalization of knowledge by disseminating clinically relevant advances in the field of cardiac arrest across disciplines.

Methods

An electronic search of PubMed using keywords related to cardiac arrest was conducted. Title and abstracts retrieved by these searches were screened for relevance, classified by article type (original research or review), and sorted into 7 categories. Screened manuscripts underwent standardized scoring of overall methodological quality and impact on the categorized fields of study by reviewer teams lead by a subject-matter expert editor. Articles scoring higher than 99 percentiles by category-type were selected for full critique. Systematic differences between editors’ and reviewers’ scores were assessed using Wilcoxon signed-rank test.

Results

A total of 3348 articles were identified on initial search; of these, 1364 were scored after screening for relevance and deduplication, and forty-five underwent full critique. Epidemiology & Public Health represented 24% of fully reviewed articles with Prehospital Resuscitation, Technology & Care, and In-Hospital Resuscitation & Post-Arrest Care Categories both representing 20% of fully reviewed articles. There were no significant differences between editor and reviewer scoring.

Conclusions

The sheer number of articles screened is a testament to the need for an accessible source calling attention to high-quality and impactful research and serving as a high-yield reference for clinicians and scientists seeking to follow the ever-growing body of cardiac arrest-related literature. This will promote further development of the unique and interdisciplinary field of cardiac arrest medicine.

Systematic review of the characteristics of brief team interventions to clarify roles and improve functioning in healthcare teams

AIM

Describe brief (less than half a day) interventions aimed at improving healthcare team functioning.

METHODS

A systematic review on brief team interventions aimed at role clarification and team functioning (PROSPERO Registration Number: CRD42018088922). Experimental or quasi-experimental studies were included. Database searches included CINAHL, Medline, EMBASE, PUBMED, Cochrane, RCT Registry-1990 to April 2020 and grey literature. Articles were screened independently by teams of two reviewers. Risk of bias was assessed. Data from the retained articles were extracted by one reviewer and checked by a second reviewer independently. A narrative synthesis was undertaken.

RESULTS

Searches yielded 1928 unique records. Final sample contained twenty papers describing 19 studies, published between 2009 and 2020. Studies described brief training interventions conducted in acute care in-patient settings and included a total of 6338 participants. Participants' socio-demographic information was not routinely reported. Studies met between two to six of the eight risk of bias criteria. Interventions included simulations for technical skills, structured communications and speaking up for non-technical skills and debriefing. Debriefing sessions generally lasted between five to 10 minutes. Debriefing sessions reflected key content areas but it was not always possible to determine the influence of the debriefing session on participants' learning because of the limited information reported.

DISCUSSION

Interest in short team interventions is recent. Single two-hour sessions appear to improve technical skills. Three to four 30- to 60-minute training sessions spread out over several weeks with structured facilitation and debriefing appear to improve non-technical skills. Monthly meetings appear to sustain change over time.

CONCLUSION

Short team interventions show promise to improve team functioning. Effectiveness of interventions in primary care and the inclusion of patients and families needs to be examined. Primary care teams are structured differently than teams in acute care and they may have different priorities.
