Assessment of the Benefit of an Inclusive Health Organization on the Prognosis of Severe Trauma Patients (TRAUMINXCLUSIF)

Appropriate management reduces the mortality of severe trauma victims. This is based on a pre-hospital medical assessment of severity, the initiation of life-saving treatments at the pre-hospital level, and referral to a hospital with human and material resources adapted to the patient's severity. The objective of this research project is to show that the 28-day mortality after severe trauma is lower in a structured health system, compared to a non-structured system.

Detailed Description

Appropriate management reduces the mortality of severe trauma victims defined by an Injury Severity Score (ISS) greater than 15 or the need for specialized and/or urgent treatment. This is based on a pre-hospital medical assessment of severity, the initiation of life-saving treatments at the pre-hospital level, and referral to a hospital with human and material resources adapted to the patient's severity.

The trauma hospital organisation in France is of the "exclusive" type. It contrasts trauma centres with other hospitals, only providing care for severe trauma victims in the former, which are most often confused with university hospitals. The choice of referral to this type of centre is made using a triage algorithm known as "de Vittel". In addition to an insufficient network within a region leading to longer hospital access time, this organisation leads to saturation of the referral centres by patients with few lesions. For this reason, this organisation has been rethought in an innovative way within the Auvergne-Rhône-Alpes region, in favour of an "inclusive" system that takes the form of a network of hospitals with capacities to receive severely traumatised patients that vary according to their equipment and personnel. Patients are referred within this network according to their severity category (unstable, stabilized or stable).

The main objective is to show that the 28-day mortality of severely traumatized persons oriented according to their severity in an inclusive system is lower, at identical severity, than in a conventional exclusive system in which the orientation is guided by the Vittel algorithm.

Secondary objectives are to show that the management of severe traumatized persons oriented according to their severity in an inclusive system, compared to the management in an exclusive conventional system in which the orientation is guided by the Vittel/ASCOTT algorithm, is associated, at identical severity, with :

• Less under-triage;
• Less over-triage;
• A lower incidence of secondary transfers to a trauma center;
• A greater number of days living without mechanical ventilation (during the first 28 days);
• More days living without resuscitation (within the first 28 days);
• More frequent and rapid use of whole-body CT scans with contrast injection;
• More frequent and rapid use of specialized emergency therapies (laparotomy or hemostasis thoracotomy, embolization, craniectomy, intracranial pressure measurement, chest drainage).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
28-day mortality	The primary endpoint will be 28-day mortality, defined as the occurrence of death from any cause within the first 28 days following trauma.	28th day

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Undertriage	Undertriage, defined as the management outside the trauma care system adapted to their condition of patients whose ISS is strictly greater than 15, or presenting at least one of the following criteria: the need for transfusion of more than 4 red blood cell concentrates during the first 6 hours of management;; the presence of severe head trauma with CT scan lesions;; the presence of a spinal cord injury;; the need for specialized emergency surgery (laparotomy or hemostasis thoracotomy, embolization, craniectomy, intracranial pressure measurement, chest drainage) within the first 24 hours;; the need for a secondary inter-hospital transfer to a trauma center. This variable will be assessed at the end of the 28th day, based on the data contained in the medical file and the administrative file.	28th day
Over-triage	Over-triage, defined by the management of severely traumatized patients in the trauma centre and whose ISS is less than or equal to 15 and who do not present any of the following criteria : the need for transfusion of more than 4 red blood cell concentrates during the first 6 hours of management;; the presence of severe head trauma with CT scan lesions;; the presence of a spinal cord injury;; the need for specialized emergency surgery (laparotomy or hemostasis thoracotomy, embolization, craniectomy, intracranial pressure measurement, chest drainage) within the first 24 hours;; the need for transfer to a trauma center. This variable will be evaluated at the end of the 28th day, based on the data contained in the medical file and in the administrative file	28th day
Transfer to a trauma centre	Tranfer to a trauma centre at the end of the pre-hospital phase. This criterion will be evaluated at the time of admission of the patient out of the SMUR ambulance. Trauma centres are considered to be hospitals with a unit dedicated to the care of these patients, identified as such by the territorially competent regional health agency;	1 day
Secondary inter-hospital transfer	The need for secondary inter-hospital transfer to a specialized trauma centre or a higher-level trauma centre. This variable is defined as the transfer of the patient, during the study period, from a hospital that does not have a trauma centre to the trauma centre of a hospital that does, or the transfer of the patient from a hospital trauma centre to a higher level trauma centre (III to II, II to I, III to I).
