Background: The ordinary process for the ambulance nurse is to give prehospital care and transport all patients to the emergency ward regardless of the patients’ medical conditions. The Ambulance organisation south of Sweden has introduced a model of prehospital care for all adult patients with different severities of illness.

Aim: The main focus of the study is to give a faster prehospital assessment in collaboration with the ambulance nurse and primary health care. The secondary focus is to investigate the use of RETTS (Rapid Emergency Triage, and Treatment System) while writing the information regarding the patient. If the patient’s condition turns out to be level GREEN by RETTS, the ambulance nurse contact with the primary care physicians for a dialogue and together they decide which level of care is the most appropriate for the patient’s condition. There are three levels of care; 1. The patient is able to stay at home with supervision from the primary health care. 2. The ambulance transporting the patient to the primary health care unit for assessment. 3. The ambulance transport the patient to the emergency ward.

Method: The study design was to exploratory interventions study. The data was conducted in all Electronic Health Records during August – September 2014 (N=67). The ambulance nurse assess patients from 18 years and older with (RETTS). There are three levels of care; 1. The patient is able to stay at home with supervision from the primary health care. 2. The ambulance transporting the patient to the primary health care unit for assessment. 3. The ambulance transport the patient to the emergency ward. The data was analyzed by a descriptive method conducted by statistics from the nurses while using the clinical support systems (RETTS) for decision-making.

Results: Preliminary results will be presented with focus on clinical decision-making, clinical support systems by RETTS, and how ambulance nurse administrated their decision in Electronic Health Records.
