Background: In the 2018 advisory opinion concerning the realignment of healthcare, it is advocated that in order to relieve pressure on emergency departments (ED) prehospital medical emergency services should be given the option to directly transport suitable patients to doctors' offices.
Objectives: To determine the prevalence of patients treated by prehospital emergency services that have the potential to be directly allocated to a primary care provider.
Materials and methods: Preclinical and clinical data of adult patients who in a 2-month period were transported to the ED of a university hospital by an ambulance were evaluated. To determine a safe and meaningful transport directly to a doctor's office, a stepwise assessment was carried out: patients were categorized on the basis of the prehospital assessment of urgency as "urgent" (contact to doctor necessary within a maximum time of 30 min) and "less urgent" (contact to doctor not necessary within 30 min, maximum 120 min). "Less urgent" patients were further divided and those treated as outpatients were identified. This group was further restricted to cases whose administrative reception in the ED was documented Monday-Friday between 8 am and 7 pm. In addition, these cases were further differentiated with regard to medical content and compared with the triage results in the ED (Manchester Triage, MTS).
Results: In all, 1260 patients were brought to the ED by ambulance within the study period (total number of patients treated in this time period n = 11,506); 894 cases had a documented prehospital level of urgency and could therefore be included. Of these n = 477 (53.4%) were categorized as "less urgent"; 317 (66.5%) of these "less urgent" cases were treated as outpatients in the ED, and n = 114 (23.9%) in a time frame potentially suitable for direct transport to doctors' offices, which is 1% of all patients treated in the ED in the time period examined. However, 70 of the cases suitable for doctors' office (63.6% of n = 110 with documented MTS) were rated more urgent in the ED. With regards to prehospital complaints and documented diagnosis we assume employment of a relevant amount of resources in the treatment of these cases.
Conclusions: EDs could be relieved from every tenth patient brought in by prehospital emergency services (1% of all patients treated) during normal offices hours by direct allocation to doctors' offices. Regarding patient's safety this process however has to be seen critically as > 60% of these cases were potentially undertriaged. Necessary resources for diagnostics and treatment have to be available in the doctors' offices and known to prehospital emergency services. Primary assignment of patients to doctors' offices by prehospital emergency can only relieve urban EDs to a negligible extent, is potentially dangerous and linked to a tremendous logistic effort.
