Can virtual-reality simulation ensure transthoracic echocardiography skills before trainees examine patients?

Ultrasound in anesthesiology in the Nordic countries-Protocol of an international survey on availability, frequency of use, operator training, and certification

BACKGROUND

Over the past decade, ultrasound utilization has increased within anesthesia and intensive care medicine, enhancing patient safety and diagnostic accuracy. However, the frequency of ultrasound usage and operator training in the Nordic countries remain unclear. This project aims to perform a survey on ultrasound availability, daily clinical use, and how ultrasound skills are trained and assessed, among anesthesiologists.

METHODS

This online cross-sectional survey will include anesthesiologists from the Nordic countries. The survey will adhere to the CROSS checklist. Survey items will be developed based on a formative model with a conceptual model, consisting of three main parts, including demographics, ultrasound machines and use, and skills development and assessment. The clinical relevance of items will be secured by including anesthesiologists of various levels of experience in the development of the survey. Furthermore, experienced researchers in medical education will participate in the development, contributing with relevant medical educational perspectives. Data will be summarized using a non-parametric descriptive approach. A chi-squared test will examine relevant relationships between certain answers.

RESULTS

Results will be published in a peer-reviewed journal and presented at relevant scientific conferences and meetings.

CONCLUSION

This study may find a high availability of ultrasound machines and frequent use in the clinical departments. Despite this expected daily use of ultrasound, missing standardized structured skills acquisition and assessment could be uncovered. The results of this study may contribute to mapping various aspects of clinical ultrasound and skills development for further use in research.

Using virtual reality simulation for training practical skills in musculoskeletal wrist X-ray - A pilot study

OBJECTIVES

Using virtual reality (VR), students of radiography can practice acquisition and positioning of musculoskeletal radiographs and get immediate feedback on their performance within the simulator. The purpose of this study was to assess usability of a newly developed VR simulator and to explore self-perceived clinical readiness (SPCR) of radiography students before and after training acquisition of wrist radiographs in the VR simulator.

MATERIAL AND METHODS

A prospective methodology was applied where the students (n = 10) estimated their own SPCR in regard to acquisition of wrist radiographs pre- and post-VR training. A questionnaire on usability, realism, and educational value of the simulator was answered post-VR training. Usability and SPCR scores were calculated. The student's paired t-test was applied to explore the impact of VR training on SPCR.

RESULTS

The students (90%) reported that the simulator was realistic and they thought that it could contribute to learning. The pre- and post-SPCR scores were 75 (95% confidence interval [CI]: 54-96) and 77 (95% CI: 59-95), respectively. There was no significant difference (P = 0.4574) between the pre- and post-SPCR scores.

CONCLUSION

Results indicated that the concept of training acquisition and positioning of wrist radiographs in a VR simulator is feasible with positive feedback from the students. The SPCR scores improved slightly, although not statistically significant, after completion of the training session.
