Immediate and 1-Year Chest Compression Quality: Effect of Instantaneous Feedback in Simulated Cardiac Arrest

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.

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.

Cardiopulmonary resuscitation retention training for hospital nurses by a self-learner skill station or the traditional instructor led course: A randomised controlled trial

Introduction

Intrahospital cardiac arrest has a steep mortality and high-quality cardiopulmonary resuscitation (CPR) is essential for favourable outcome. Instructor led (IL) CPR training is resource demanding and instructor free, feedback providing CPR skill stations (SS) could provide a means to enable the needed frequent retraining. The main objective of this study was to test the hypothesis that there was no difference between IL and SS training.

Methods

A total of 129 hospital nurses were randomised to CPR retraining in three groups; skill station with retraining at 2 months (SS-R), skill station without retraining (SS) and instructor led training (IL). Participants were tested at baseline, 2 and 8 months. The skill station groups were combined (c-SS) for analysis at baseline and 2 months when comparing to IL.

Results

Baseline characteristics for the three groups differed significantly, however c-SS and IL groups performed equally at baseline and testing at 2 months. At 8 months the SS group performed 71% correct ventilations compared to 54% in the IL group (p = 0.04), but CPR quality was otherwise equal. Longitudinal analysis showed SS-R performed 3.4 mm deeper compressions at final evaluation compared to baseline (p = 0.02) and 2.8 mm deeper compared to 2-month test (p = 0.02). No effects of retraining at 2 months could be detected at final comparison of SS-R and SS groups.

Conclusion

CPR training using a skill station led to equal performance at 2 and 8 months compared to instructor led training. Feedback-providing skill stations could be a feasible tool for required frequent retraining.

External Cardiac Massage Training of Medical Students: A Randomized Comparison of Two Feedback Methods to Standard Training

BACKGROUND

The most recent recommendations support learning of external cardiac massage (ECM) through feedback devices.

OBJECTIVES

The objective was to compare the effects on immediate and 3-month retention of ECM technical skills when using feedback devices compared with training without feedback as part of a half-day training session in medical students.

METHODS

This randomized study was performed using the Resusci Anne QCPR manikin in 64 medical students. We compared the quality of ECM with nonfeedback training in the control group (group 1) vs. 2 feedback learning methods (group 2, PocketCPR and group 3, Skill Reporter each used with visual display available to the trainee). At the end of the training session and 3 months later, students performed chest compressions blindly during a 2-min assessment session. The median compression score was the primary outcome for assessing immediate and long-term retention.

RESULTS

Regarding immediate retention, the median compression score was significantly lower in group 1 (23%) than in groups 2 (81%) and 3 (72%) (p < 0.05) with no difference between the 2 feedback methods. At 3 months, mean compression scores remained high but not significantly different between the 2 feedback groups.

CONCLUSION

The use of a feedback device used for ECM training improves the quality of immediate retention of technical ECM skills compared with traditional teaching in medical students. At 3 months, the 2 groups with feedback retained a high level of performance. No significant difference could be demonstrated between the 2 feedback methods.

Human Factors and Simulation in Emergency Medicine

This consensus group from the 2017 Academic Emergency Medicine Consensus Conference "Catalyzing System Change through Health Care Simulation: Systems, Competency, and Outcomes" held in Orlando, Florida, on May 16, 2017, focused on the use of human factors (HF) and simulation in the field of emergency medicine (EM). The HF discipline is often underutilized within EM but has significant potential in improving the interface between technologies and individuals in the field. The discussion explored the domain of HF, its benefits in medicine, how simulation can be a catalyst for HF work in EM, and how EM can collaborate with HF professionals to effect change. Implementing HF in EM through health care simulation will require a demonstration of clinical and safety outcomes, advocacy to stakeholders and administrators, and establishment of structured collaborations between HF professionals and EM, such as in this breakout group.

Benefits of Visual Feedback on Cardiopulmonary Resuscitation Training: A Non-Randomised Manikin Study with Bystanders

Introduction

Cardiopulmonary resuscitation (CPR) is vital for the survival of people who has suffered a cardiac arrest. In order to achieve a good quality CPR performance, rescuer needs a good training which could be gotten with the use of feedback devices. The aim of this study was to compare the use of visual feedback device in CPR training to learning without feedback.

Methods

Ninety-nine subjects without basic life support knowledge participating in the study were divided into three groups. All of them carried out two tests: 2 minutes of CPR with compressions and ventilations. First two groups received trainings on CPR between the tests (experimental groups): one group with instructor-led training and the other one with visual feedback device. The third group did not receive any training between the tests (control group).

Results

In the first test no differences among the three groups were found. The experimental groups improved their scores in the last test. The number of correct chest compressions by hand position and depth, and the number of correct rescue breaths was increased. The experimental group with visual feedback CPR training achieved better scores of quality CPR in the second test than the instructor-led training group.

Conclusions

The visual feedback and instruction-led training have positive effects on the quality CPR. The use of visual feedback during learning has greater benefits than instruction-led training in the three variables analysed.

Randomized crossover trial of a pressure sensing visual feedback system to improve mask fitting in noninvasive ventilation

BACKGROUND AND OBJECTIVE

A good mask fit, avoiding air leaks and pressure effects on the skin are key elements for a successful noninvasive ventilation (NIV). However, delivering practical training for NIV is challenging, and it takes time to build experience and competency. This study investigated whether a pressure sensing system with real-time visual feedback improved mask fitting.

METHODS

During an NIV training session, 30 healthcare professionals (14 trained in mask fitting and 16 untrained) performed two mask fittings on the same healthy volunteer in a randomized order: one using standard mask-fitting procedures and one with additional visual feedback on mask pressure on the nasal bridge. Participants were required to achieve a mask fit with low mask pressure and minimal air leak (<10 L/min). Pressure exerted on the nasal bridge, perceived comfort of mask fit and staff- confidence were measured.

RESULTS

Compared with standard mask fitting, a lower pressure was exerted on the nasal bridge using the feedback system (71.1 ± 17.6 mm Hg vs 63.2 ± 14.6 mm Hg, P < 0.001). Both untrained and trained healthcare professionals were able to reduce the pressure on the nasal bridge (74.5 ± 21.2 mm Hg vs 66.1 ± 17.4 mm Hg, P = 0.023 and 67 ± 12.1 mm Hg vs 60 ± 10.6 mm Hg, P = 0.002, respectively) using the feedback system and self-rated confidence increased in the untrained group.

CONCLUSION

Real-time visual feedback using pressure sensing technology supported healthcare professionals during mask-fitting training, resulted in a lower pressure on the skin and better mask fit for the volunteer, with increased staff confidence.

A Simulation-based Randomized Controlled Study of Factors Influencing Chest Compression Depth

INTRODUCTION

Current resuscitation guidelines emphasize a systems approach with a strong emphasis on quality cardiopulmonary resuscitation (CPR). Despite the American Heart Association (AHA) emphasis on quality CPR for over 10 years, resuscitation teams do not consistently meet recommended CPR standards. The objective is to assess the impact on chest compression depth of factors including bed height, step stool utilization, position of the rescuer's arms and shoulders relative to the point of chest compression, and rescuer characteristics including height, weight, and gender.

METHODS

Fifty-six eligible subjects, including physician assistant students and first-year emergency medicine residents, were enrolled and randomized to intervention (bed lowered and step stool readily available) and control (bed raised and step stool accessible, but concealed) groups. We instructed all subjects to complete all interventions on a high-fidelity mannequin per AHA guidelines. Secondary end points included subject arm angle, height, weight group, and gender.

RESULTS

Using an intention to treat analysis, the mean compression depths for the intervention and control groups were not significantly different. Subjects positioning their arms at a 90-degree angle relative to the sagittal plane of the mannequin's chest achieved a mean compression depth significantly greater than those compressing at an angle less than 90 degrees. There was a significant correlation between using a step stool and achieving the correct shoulder position. Subject height, weight group, and gender were all independently associated with compression depth.

CONCLUSION

Rescuer arm position relative to the patient's chest and step stool utilization during CPR are modifiable factors facilitating improved chest compression depth.
