Prähospitale Anlage von Thoraxdrainagen: Welche Faktoren sind mit einem subjektivem Sicherheitsgefühl assoziiert?

Abstract

Background

The prehospital placement of chest tubes is a rare but potentially life-saving procedure. A high level of subjective confidence with the procedure is essential for emergency medical doctors. This study aims to identify if there is a statistically significant difference in the subjective sense of confidence in prehospital chest tube placement regarding medical experience and qualification, clinical routine, and attendance at simulation courses.

Methods

Prehospital emergency physicians of three emergency medical services in Southwest Saxony, Greifswald, and Vechta, Germany, were invited to participate in an online survey from January to March 2022 using the online survey service limesurvey. The question “Do you feel confident in chest tube placement?” was used to measure the subjective level of confidence. Answers were compared with data concerning medical qualification, experience in prehospital emergency medicine, clinical routine, and attendance at simulation courses. Statistical analysis was performed using chi-squared test and Fisher’s exact test.

Results

Three out of four participants felt confident in chest tube placement (53/71; 74.6 %). More than half of the participants reported that they did not perform this procedure regularly (35/53, 66 %). Subjective confidence was highest in physicians who regularly place chest tubes during their non-prehospital work (34/37; 91,9 %; p < 0.001), and more often when participants had clinical routine and attended simulation courses than when none of this applied (p = 0.012). Attendance at simulation courses alone was not associated with a higher level of confidence (p = 0.002). Specialists showed significantly more often subjective confidence in chest tube placement (p = 0.0401).

Conclusion

Prehospital chest tube placement is rare, but potentially lifesaving. An adequately high level of subjective confidence in the placement of chest tubes is a key condition for prehospital emergency doctors. Inhospital clinical routine and attendance at simulation courses are significantly associated with high levels of confidence. Our data indicate that working only in prehospital emergency settings without further clinical routine or medical specialization is not sufficient for achieving and ensuring subjective confidence in chest tube placement.
