Abstract
BACKGROUND:Lung ultrasound (LUS) is a point-of-care technique which can quickly identify or rule out pathological findings. To date, it is unclear if knowledge about the use of LUS is readily available. OBJECTIVES: We aimed to identify how much knowledge about the use of LUS is present, if there is a need for teaching in LUS, as well as the preferred teaching method in LUS. MATERIALS AND METHODS: A total of 54 participants from two university departments of anesthesiology were randomized into the groups Online, Classroom, and Control. The Online group was taught by videos, the Classroom group by a traditional lecture with hands-on training, and the Control group was not taught at all. We conducted a pre- and posttest as well as a retention test 4 weeks after the end of the study by means of a survey (comparison with Mann-Whitney U test or t‑test, respectively, with p < 0.05 considered to be significant). RESULTS:LUS is used "rarely" or "never", and mainly if there is a suspicion for pleural effusion (41.3%). There is a need for LUS (Online: 21.7%; Classroom: 60.9%; Control: 62.5%, p < 0.05). Hybrid teaching consisting of classroom-based and online-based teaching is preferred by the users (Online: 52.2%; Classroom: 56.5%; Control: 62.5%). At the end of the study, 32.6% of the participants of the intervention groups had used LUS in the diagnosis of a pneumothorax. Of the participants, 93.5% planned to use LUS more often in the future. CONCLUSIONS:LUS is rarely used. There is a considerable need for teaching of LUS. Internet-based teaching and traditional lectures are considered equal. Both teaching methods improve the knowledge about LUS and lead to increased use of LUS in daily practice. The participants prefer hybrid teaching incorporating both teaching methods.
