[Implications of prehospital estimation of trauma patients for the treatment pathway-An evaluation of the TraumaRegister DGU®]. / Implikationen der prähospitalen Einschätzung des Traumapatienten auf den Behandlungsverlauf ­ Eine Auswertung aus dem TraumaRegister DGU®.

ABSTRACT

BACKGROUND: In the prehospital acute treatment phase of severely injured patients, the stabilization of the vital parameters is paramount. The rapid and precise assessment of the injuries by the emergency physician is crucial for the initial treatment and the selection of the receiving hospital. OBJECTIVE: The aim of this study was to determine whether the prehospital emergency medical assessment has an influence on prehospital and emergency room treatment. MATERIAL AND METHODS: Data from the TraumaRegister DGU® between 2015 and 2019 in Germany were evaluated. The prehospital emergency medical assessment of the injury pattern and severity was recorded using the emergency physician protocol and compared with the in-hospital documented diagnoses using the abbreviated injury scale. RESULTS: A total of 47,838 patients with an average injury severity score (ISS) of 18,7 points (SD 12.3) were included. In summary, 127,739 injured body regions were documented in the hospitals. Of these, a total of 87,921 were correctly suspected by the emergency physician Thus, 39,818 injured body regions were not properly documented. In 42,530 cases a region of the body was suspected to be injured without the suspicion being confirmed in the hospital. Traumatic brain injuries and facial injuries were mostly overdiagnosed (13.5% and 14.7%, respectively documented by an emergency physician while the diagnosis was not confirmed in-hospital). Chest injuries were underdocumented (17.3% missed by an emergency physician while the diagnosis was finally confirmed in-hospital). The total mortality of all groups was very close to the expected mortality calculated with the revised injury severity classification II(RISC II)-score (12.0% vs. 11.3%). CONCLUSION: In the prehospital care of severely injured patients, the overall injury severity is often correctly recorded by the emergency physician and correlates well with the derived treatment, the selection of the receiving hospital as well as the clinical course and the patient outcome; however, the assessment of injuries of individual body regions seems to be challenging in the prehospital setting.
