BACKGROUND

Each year there are 7.3 million emergencies for the German rescue service, trend rising and around 59% of the emergency patients are treated by paramedics only; however, most of the studies focus on physicians, while their practical skills at the scene are rarely necessary. Accordingly, the responsibility for the patient lies with the paramedics most of the time. Their duty is to execute life-saving measures, stabilize the patient for the transport and the regular documentation of the operation. Retrospectively, the emergencies can only be analyzed based on the emergency protocols, which are mostly paper-based and handwritten. That causes an increased effort in the evaluation, which makes studies for the whole country hardly feasible. As of now there are only few data on quality of healthcare and documentation by the paramedics. Both were analyzed in this survey based on the emergency protocols.

METHOD

A retrospective analysis of emergency protocols from June to July 2018 took place in Aachen, a major German city. A specific feature of Aachen is a 24‑h available emergency physician via telemedicine. The quality of documentation and healthcare was analyzed by including standard operating procedures. Primary endpoints were the frequency of documentation, the achievement of complete documentation, the correct indications for a physician, the development of critical vital signs and the average on-scene time of the ambulance.

RESULTS

Overall, 1935 protocols were analyzed. A complete documentation was achieved in 1323 (68.4%) suspected diagnoses, 456 (23.6%) anamneses, 350 (18.1%) initial and 52 (2.7%) vital signs at handover. Based on the documentation, there were 531 cases (27%) of patients treated by paramedics only, even though a physician would have been indicated. Out of those patients 410 critical initial vital signs were documented of which 69 (16.8%) improved, while there was no documentation of vital signs at handover in 217 (52.9%). Also, there was a significantly prolonged on-scene time for patients with belated indications for an emergency physician with 15:02 min in comparison to 13:05 min for patients without indications.

CONCLUSION

Deficient documentation was found in multiple cases and several important vital signs for a complete differential diagnosis were missing. Furthermore, a quarter of all patients might have benefited from an emergency physician as they were taken to hospital with no or insufficient treatment, despite standard operating procedures. From a forensic point of view there is an alarmingly incomplete documentation of vital signs at handover. The on-scene time in general was within the predetermined time frame, but can still be reduced in different scenarios. Overall, we recommend strict adherence to the standard operating procedures and algorithms, to remove unnecessary documentation and implement a structured quality assurance. Moreover, the quality of treatment might benefit from the rising number of more specialized paramedics and an increasing use of telemedicine.
