Zusammenfassung

Hintergrund

Durch Lungenultraschall (LUS) können pathologische Befunde schnell und bettseitig nachgewiesen bzw. ausgeschlossen werden. Unklar ist, wie verbreitet Kenntnisse über LUS sind.

Ziel der Arbeit

Ermittlung des Kenntnisstands im Bereich LUS sowie des Bedarfs an Schulungsangeboten und der geeigneten Unterrichtsform.

Material und Methoden

Es wurden 54 Teilnehmer aus 2 anästhesiologischen Universitätskliniken in die Gruppen Online, Frontal und Kontrolle randomisiert. Die Online-Gruppe wurde durch Lehrvideos, die Frontalgruppe durch Frontalvortrag mit Praxistraining und die Kontrollgruppe nicht geschult. Zum Studienbeginn, direkt nach den Lehreinheiten und 4 Wochen später absolvierten die Probanden jeweils einen Test mittels Fragebogen (Vergleich mittels Mann-Whitney-U- bzw. t‑Test; Signifikanzniveau p < 0,05).

Ergebnisse

LUS wird eher „selten“ bis „nie“ genutzt, hauptsächlich bei Verdacht auf Pleuraerguss (41,3 %). Der Bedarf an LUS wird mit „häufig“ angegeben (Online-Gruppe: 21,7%; Frontalgruppe: 60,9%; Kontrollgruppe 62,5 %; p < 0,05). Eine Mischform aus Frontalunterricht und internetbasiertem Selbststudium wird bevorzugt (Online-Gruppe: 52,2 %; Frontalgruppe: 56,5 %; Kontrollgruppe: 62,5 %). Zum Studienende hatten 32,6 % der Teilnehmer der beiden Interventionsgruppen LUS zur Diagnostik eines Pneumothorax angewandt; 93,5 % der Probanden gaben an, zukünftig häufiger auf LUS zurückzugreifen.

Diskussion

LUS wird selten angewandt, der Bedarf an Lehreinheiten zu diesem Thema ist aber hoch. Internetbasierte Lehreinheiten gelten als dem Frontalunterricht gleichwertig. Beide Unterrichtsformen verbessern die Kenntnisse in LUS und führen zu einer Mehranwendung von LUS im klinischen Alltag. Die bevorzugte Unterrichtsform ist hybrides Lernen aus beiden Unterrichtsformen.

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.
