摘要

Background

With the revision of the German S3 guideline on polytrauma/severe injury management, mechanism-based criteria for trauma team activation (TTA) were largely abandoned. At the same time, the use of third-party service (TPS)-eCall systems, which transmit objective crash data, is gaining importance.

Objective

What challenges and potentials arise in the use of TPS-eCall data for prehospital and clinical interpretation of crash mechanisms?

Materials and methods

Prospective observational study with trend analysis of activation frequency and case-based evaluation of all severely injured persons using emergency medical services (EMS), hospital, and registry data. All TPS-eCall incidents in the city of Essen between 01/2022 and 05/2025 were analyzed and linked to EMS data, treatment reports from a supraregional trauma center, and the TraumaRegister of the German Society for Trauma Surgery.

Results

A total of 209 TPS-eCall activations were recorded, showing a significant monthly increase (β = 0.16; 95% CI 0.06–0.26; p < 0.01; R2 = 0.21). In all, 25 persons were transported to the emergency department of the participating hospital, of whom 11 (44%) were treated by a trauma team. Four persons (16%) met the inclusion criteria of the TraumaRegister DGU®. Interpretation problems of TPS-eCall data were present in all cases.

Conclusion

TPS-eCall systems can complement prehospital assessment. However, heterogeneous data quality, lack of standardization, and missing technical integration currently complicate interpretation. Nevertheless, the increasing number of cases and the expected improvement in data quality suggest that TPS-eCalls may play a relevant role in future prehospital decision-making.
