AmbulaNCE Teletransmited PHOtography for Trauma REgulation

Study Overview
=================
Brief Summary
-----------------
Physicians in charge of medical regulation within French SAMU have to take difficult decisions regarding patient's orientation (in or out-of hospital care) but suffer from lack of information. Such information usually consist in a simple phone conversation without any visual information. Visual assesment of the situation would be of great help, especially for traumatized patients. Private Ambulance societies all over territory in charge of SAMU 86 now work with teletransmission devices allowing photography transmission. The objective of the study is to determine if routine use of teletransmitted photography help SAMU 86's physians for a better orientation of non-severe traumatized patients, especially by avoiding unnecessary transportations to Emergency Departments.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Impact of Photography on patient orientation | Number of patient dispatched anywhere else than the local hospital after ambulance assesement. Either the patient was dispatched to a higher level hospital (i.e. if the local hospital doesn't provide surgical facility when the patient needs it) or he was leaved at home and oriented to a general practitioner. | 1 - 2 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Undertriage | To evaluate the number of patients initially oriented to out-of hospital care that needed to go to emergency department during following days | 10 days | 
| Overtriage | To evaluate the number of patients initially oriented to in-hospital care when it wasn't necessary | 10 days |
