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.
