Objective: In this study we evaluated the convenience of the transports and the prehospital interventions of the cases admitted to a third level hospital with the 112 ambulance service together with their demographic features. Material and Methods: All of the adult patients admitted to the hospital with the 112 ambulance service between January 2009, 1 and January 2010, 31 were included in the study. Patients were evaluated with the 112 ambulance patient register form data collected from the archives of the hospital and the computer recordings. Variables were sex, transport duration, admission time, place of event, reason of the transport, prehospital interventions of the ambulance team, initial diagnosis, disposition of the patint recorded in the emergency department. Results: The ambulance use rate of the patients admitted to our hospital was 0.54%. Of the patients 53.5% were male and 46.5% were female. The admission time from the scene of event was 20-29 minutes. 49% ofpatients were transported enrolled from the home in 49.3%. Of the 75.1% patients transported for diagnosis and treatment, 17.6% had been sent for consultation and 7.3% dispatched from an other hospital. 82.6% of the dispatched patients were admitted without approval. Forty precentage of the dead patients admitted to the hospital by ambulance were not intubated. Thirty-eight percentage of the intubated patients were reintubated in the emergency department after admission. Of the patients transported by the 112 ambulance service, 74% were discharged and 24.1% were hospitalised. Conclusion: The interventions carried out on the patients admitted to the emergency department by ambulance are not sufficient. It is thought that the education programmes are concentrated on inservice and the emergency medical services organisation should be developed.
