Cadaver as an educational tool increasing the effectiveness of Combat Application Tourniquet use in extremity injuries.

Ulus Travma Acil Cerrahi Derg 2021 Mar;27(2):161-166

University of Natural Sciences and Humanities, Faculty of Medical Sciences and Health Sciences, Siedlce-Poland.

Background: One of the most frequent life-threatening emergencies is extremity haemorrhage. In such cases, patient survival depends on a fast on-scene intervention. Thus, both the potential witnesses and medical emergency staff should have the ability to control haemorrhages. However, simulator-based courses do not fully reflect the structures and physiology of the human body. Therefore, invasive procedure training in trauma patients is limited. The present study aims to evaluate the effectiveness of cadavers as educational tools during a training course in extremity haemorrhage control with the use of the Combat Application Tourniquet (CAT).

Methods: This study was conducted among 31 paramedic students, who applied a tourniquet to the upper extremity of an unembalmed (fresh) human cadaver with simulated bleeding. Two time measurements were performed, the latter being preceded by a short CAT application training on a human cadaver.

Results: The mean time needed to stop the simulated bleeding in the first attempt was 38.33 seconds (SD±35.14). After the training, the mean time decreased to 20.58 seconds (SD±5.77). A statistically significant difference was observed between these two values (p=0.004).

Conclusion: This study demonstrated that training conducted on human cadavers led to a significant improvement in the effectiveness of CAT use. Cadavers constitute a high-quality educational tool that, after adequate preparation, allows for practicing invasive medical procedures, such as extremity haemorrhage control.

Determinants of occupational burnout among employees of the Emergency Medical Services in Poland.

Ann Agric Environ Med 2019 Mar 3;26(1):114-119. Epub 2018 Sep 3.

Medical University, Warsaw, Poland.

Introduction: Occupational burnout is a multifaceted phenomenon and a problem often encountered among medical personnel. An example of such a group are workers of the Emergency Medical Services (EMS). The aim of the present study was to make an attempt to assess the level of job burnout among professionally active employees of the EMS and to compare the different occupational groups (paramedics, nurses of the system, doctors of the system) according to four analyzed factors.

Material And Methods: A cross-sectional study was performed using an on-line questionnaire. Four factors impacting the level of burnout were analyzed: 1) attitude to work; 2) workload; 3) contact with the patient; 4) attitude to stress). The minimum possible result on the scale is 36 points and the maximum - 252. Data were analysed by means of the Cronbach's alpha coefficient, the Spearman correlation, the Ramsey RESET test, the Chow test, VIF statistics.

Results: The average score for occupational burnout was 131.0 points (SD ± 31.47). The tool's reliability measured by means of Cronbach's alpha was 0.910). Both nurses and doctors obtained higher results throughout the scale (βstand.0.147 and 0.215). Significant differences were shown between the group working only in the Helicopter Emergency Medical Service (HEMS) teams and the other services (land EMS, emergency rooms, etc.) at the level of p < 0.000.

Conclusions: EMS employees encounter varying degrees of threat by occupational burnout. Doctors working in the system are shown to have the highest level of burnout, while paramedics the lowest. Among all the jobs analyzed, the lowest level of occupational burnout has been demonstrated by employees of HEMS.
