A large part of acutely ill patient's access to the health care system starts by calling the emergency number 1-1-2 and thereby getting in touch with the emergency medical dispatch center (EMDC). In most cases an ambulance is dispatched and the patient is brought to the hospital. These patients are not referred by a physician (eg. a GP) and represent an unselected subpopulation of the acutely ill patients. At present, all non-critically ill patients not evaluated by a pre-hospital physician are normally be transported to hospital as category 2 (without activated emergency lightning and sirens).A part of this patient population, however, is not critically ill and a proportion of these may not need hospital admittance . Emergency medical technicians (EM) are not allowed to treat - and- leave patients without a physician's involvement. If the EMT had 24/7 online access to medical control i.e. in form of a physician present in the EMDC , the number of patients transported to hospital for assessment may be reduced as well as response times for patients actually needing ambulance transportation. This could potentially reduce the workload on the whole healthcare system involved in the management of these patients - thereby potentially reducing costs.
The objective of this study is to evaluate if a systematic telemedical assessment by an EMDC-physician of all patients who receive an ambulance but are not critically ill and would have a category 2 transport to hospital can reduce the number of the patients that are transported to hospital and save costs and time.

| Expenses related to EMDC physician vs. savings obtained by avoided admissions | Cost of 24 hour EMDC physician vs. savings obtained by avoided admissions. Calculations of average transport related costs will be provided by the Prehospital Emergency Medical Services Aarhus and average cost of hospitalization for a patient hospitalized 24 hours or less at the emergency dept. will be provided by the Regional Hospital Horsens. The percentage of treat-and-leave patients in the intervention period will be compared to a historical control group represented by the average percentage of treat-and-leave patients for the previous 12 months (August 2013 to August 2014). The savings obtained by avoided admissions will be calculated by multiplying the difference in the proportion of treat and leave patients with the number of patients the previous 12 months who are receiving an ambulance after dialing 112. The EMDC physician related costs will be calculated from the present table of salary for specialist physicians in Denmark. | Will be assessed at the time of consultation, expected to be presented within 36 months after assessment |

Defined as the average response time for ambulances dispatched by EMDC. The average response time is calculated as the time where the emergency medical dispatcher gets an assignment (registered manually by the dispatcher) to the arrival of the ambulance at scene (registered manually by the EMS technician). This definition of response time is predefined politically and is the gold standard for this measurement across dispatch centers in Denmark. |
| Is assessed at the time the EMT registers arrival on site, expected to be presented within 36 months of assessment |
| Hospital admission within 3 days | Percentage of patients where initial hospital admission is avoided, but are admitted to hospital within 72 hours after primary contact. | Will be assessed at the 72 hours after consultation, expected to be presented within 36 months of assessment |
| Time consumption by EMDC physician | Registered as the time from receiving phone call or establishing video contact to connection is discontinued | Will be assessed within 1 minute after end of consultation, expected to be presented within 36 months after assessment |
| Cause of death | Audit on all patients dying within 30 days of primary contact. Patient's electronic medical record will be assessed by two independent consultant physicians with no relation to EMDC in order to evaluate if death of a treat-and-leave patient can be attributed to treat-and-leave | Will be assessed as soon as possible after the occurence of death, normally within 24 hours, expected to be presented within 36 months of assessment |
| Patient's evaluation | Patient's evaluation of prehospital care. Telephone survey of all included patients in the intervention period will be conducted within 72 hours after teleconsultation with EMDC-physician | Will be assessed within 72 hours after end of consultation, expected to be presented within 36 months after assessment |
