The ABCDE approach in critically ill patients: A scoping review of assessment tools, adherence and reported outcomes

Aim

The systematic Airway, Breathing, Circulation, Disability, and Exposure (ABCDE) approach is a priority-based consensus approach for the primary assessment of all categories of critically ill or injured patients. The aims of this review are to provide a wide overview of all relevant literature about existing ABCDE assessment tools, adherence to the ABCDE approach and related outcomes of teaching or application of the ABCDE approach by healthcare professionals.

Methods

A comprehensive scoping review was conducted following the Joanna Briggs Institute guidelines and reported according to the PRISMA-ScR Checklist. An a priori protocol was developed. In March 2024, MEDLINE, EMBASE, CINAHL and Cochrane library were searched to identify studies describing healthcare professionals applying the ABCDE approach in either simulation settings or clinical practice. Two reviewers independently screened records for inclusion and performed data extraction.

Results

From n = 8165 results, fifty-seven studies met the inclusion criteria and reported data from clinical care (n = 27) or simulation settings (n = 30). Forty-two studies reported 39 different assessment tools, containing 5 to 36 items. Adherence to the approach was reported in 43 studies and varied from 18-84% in clinical practice and from 29-35% pre-intervention to 65-97% post-intervention in simulation settings. Team leader presence and attending simulation training improved adherence. Data on patient outcomes were remarkably scarce.

Conclusion

Many different tools with variable content were identified to assess the ABCDE approach. Adherence was the most frequently reported outcome and varied widely among included studies. However, association between the ABCDE approach and patient outcomes is yet to be investigated.

A study on the impact of open source metaverse immersive teaching method on emergency skills training for medical undergraduate students

BACKGROUND

In recent years, the traditional simulation-based medical teaching approach has faced challenges in meeting the requirements of practical emergency medicine education. This study utilized open-source tools and software to develop immersive panoramic videos using virtual reality technology for emergency medical teaching. It aims to investigate the efficacy of this novel teaching methodology. This transformation shifted the focus from physical simulation to virtual simulation in medical education, establishing a metaverse for emergency medical teaching.

METHODS

In accordance with the curriculum guidelines, the instructors produced panoramic videos demonstrating procedures such as spinal injury management, humeral fracture with abdominal wall intestinal tube prolapse, head and chest composite injuries, cardiopulmonary resuscitation, and tracheal intubation. Using Unity software, a virtual training application for bronchoscopy was developed and integrated into the PICO4 VR all-in-one device to create a metaverse teaching environment. Fourth-year medical undergraduate students were allocated into either an experimental group (n = 26) or a control group (n = 30) based on student IDs. The experimental group received instruction through the metaverse immersive teaching method, while the control group followed the traditional simulation-based medical teaching approach. Both groups participated in theoretical and practical lessons as usual. Subsequently, all students underwent a four-station Objective Structured Clinical Examination (OSCE) to assess the effectiveness of the teaching methods based on their performance. Additionally, students in the experimental group provided subjective evaluations to assess their acceptance of the new teaching approach.

RESULTS

Before the training commenced, there were no significant statistical differences in the first aid test scores between the experimental and control groups. Following the training, the experimental group outperformed the control group in the four-station OSCE examination, with all P-values being less than 0.05. The satisfaction rate among the experimental group regarding the new teaching method reached 88.46%, reflecting levels of satisfaction and extreme satisfaction.

CONCLUSION

The open-source metaverse immersive teaching method has demonstrated a positive impact on enhancing the emergency skills of medical undergraduate students, with a high level of acceptance among students. In comparison to traditional simulated medical teaching methods, this approach requires less time and space, incurring lower costs, and is deemed worthy of wider adoption.

The effect of using desktop VR to practice preoperative handovers with the ISBAR approach: a randomized controlled trial

AIM

The aim was to investigate whether second-year undergraduate nursing students practicing the Identification-Situation-Background-Assessment-Recommendation (ISBAR) communication approach in a desktop virtual reality (VR) application had a non-inferior learning outcome compared with the traditional paper-based method when sorting patient information correctly based on the ISBAR structure.

METHODS

A non-inferior parallel group assessor blinded randomized controlled trial, conducted in simulation sessions as part of preparation for clinical placements in March and April 2022. After a 20-minute introductory session, the participants were randomized to self-practice the ISBAR approach for 45 minutes in groups of three in either an interactive desktop VR application (intervention) or traditional paper-based (TP) simulation. The primary outcome concerned the proportion of nursing students who sorted all 11 statements of patient information in the correct ISBAR order within a time limit of 5 min. The predefined, one-sided, non-inferiority limit was 13 percentage points in favor of traditional paper-based simulation.

RESULTS

Of 210 eligible students, 175 (83%) participated and were allocated randomly to the VR (N = 87) or TP (N = 88) group. Practicing in the desktop VR application (36% of everything correct) was non-inferior to the traditional paper-based method (22% everything correct), with a difference of 14.2 percentage points (95% CI 0.7 to 27.1) in favor of VR. The VR group repeated the simulation 0.6 times more (95% CI 0.5 to 0.7). Twenty percent more (95% CI 6.9 to 31.6) of the students in the VR group reported liked how they practiced. All the other outcomes including the System Usability Scale indicated non-inferiority or were in favor of VR.

CONCLUSIONS

Self-practicing with the ISBAR approach in desktop VR was non-inferior to the traditional paper-based method and gave a superior learning outcome.

Developing a virtual reality (VR) application for practicing the ABCDE approach for systematic clinical observation

BACKGROUND

The Airways, Breathing, Circulation, Disability, Exposure (ABCDE) approach is an international approach for systematic clinical observation. It is an essential clinical skill for medical and healthcare professionals and should be practiced repeatedly. One way to do so is by using virtual reality (VR). The aim was therefore to develop a VR application to be used by inexperienced health students and professionals for self-instructed practice of systematic clinical observation using the ABCDE approach.

METHODS

An iterative human-centred approach done in three overlapping phases; deciding on the ABCDE approach, specifying the requirements, and developing the application.

RESULTS

A total of 138 persons were involved. Eight clinical observations were included in the ABCDE approach. The requirements included making it possible for inexperienced users to do self-instructed practice, a high level of immersion, and a sense of presence including mirroring the physical activities needed to do the ABCDE approach, allowing for both single and multiplayer, and automatic feedback with encouragement to repeat the training. In addition to many refinements, the testing led to the development of some new solutions. Prominent among them was to get players to understand how to use the VR hand controllers and start to interact with the VR environment and more instructions like showing videos on how to do observations. The solutions in the developed version were categorised into 15 core features like onboarding, instructions, quiz, and feedback.

CONCLUSION

A virtual reality application for self-instructed practice of systematic clinical observation using the ABCDE approach can be developed with sufficient testing by inexperienced health students and professionals.
