[Analysis of a first responder system for emergency medical care in rural areas: first results and experiences].

BACKGROUND: In emergency situations it is essential to get access to medical treatment as early as possible. In Germany, the time interval from alarm to arrival should be less than 10-15 min. The emergency medical service (EMS) cannot comply with this recommendation in approximately 10% of the emergencies in Baden-Württemberg. In addition to the traditional EMS system, a voluntary system of first responders has been developed over the last years to reduce this interval. They are incorporated into the alarm system of the traditional EMS and are alarmed as soon as an emergency call arrives. Data on process times (from alarm to begin of treatment or duration of treatment until arrival of EMS) and quality are rare. In Baden-Württemberg, the emergency aid "Deutsche Lebens-Rettungs-Gesellschaft e.V. (DLRG)" Nordhardt can only estimate times and quality of primary care. The objective of this analysis was to describe and evaluate such a first responder system.
METHODS: The presented study investigated the emergency responses of a first responder system in Nordhardt, close to Karlsruhe, Germany. A total of 367 emergency data sets from 2017 containing information on operating time, medical history, suspected diagnosis and medical treatment, were evaluated. Of these, 363 anonymized emergency records including the complete information (concerning process time and medical treatment) were analyzed. The focus was on different time intervals from alarm to treatment and until arrival of the EMS. Additionally, the quality of medical treatment and the measured vital data were examined.
RESULTS: The median response time and time to access to the patient was 2 min in both. The patient was reached within approximately 4 min and treated for another 5 min until the EMS arrived. In two thirds of the patients, the vital parameters were measured, 5 patients were resuscitated, 23 received supplementary oxygen, 4 patients were ventilated and 11 patients suffering from hypoglycemia showed a clinical benefit from the early treatment. A total of 50 trauma patients were treated, 5 with cervical spine stabilization and 38 received a body check.
CONCLUSION: The first responders from Nordhardt received an emergency call nearly every day. In two thirds of the calls they were faster than the EMS as they usually have local sites with a shorter distance to the emergency scene where they are able to deal with critical medical cases until the EMS arrives. Despite the small case numbers, it could be concluded that the early medical treatment with respect to resuscitation based on earlier arrival on site may help to increase the survival rate of patients. The first responders were also able to manage airway problems with additional oxygen or other airway devices. Other medical treatment performed by the first responders, such as administration of glucose in hypoglycemic patients positively affected the patient's condition. There is a tactical advantage to include first responders in traditional EMS services. Further studies are needed to examine these questions in larger samples also over a longer time period. Standardization and digitalization of the records could help to gain more data in this field.
