Probabilistic Risk Modeling for Disorder Post Traumatic Stress (PTSD)

Status Enrolling by invitation

Clinical Trial Summary

The scientific approach of this project proposes to build a cohort of "psychological injuries" post-attack of 13 November 2015. This is called patients "involved", ie patients who directly witnessed the events and having the most either came under automatic gunfire or were close to an explosion, whether or not physically injured.

The main objective is to define and validate a model of transition from acute stress disorder (ASD) to posttraumatic stress disorder (PTSD) for better detection of the risk of unfavorable and thus better patient supported.

The first step is to determine independent risk factors found in analytic prospective cohort study.

Bayesian models are well suited to exercise because they can integrate (i) the context related to the patient, (ii) the context related to the trauma itself, and (iii) the immediate reactions and long-term to the latter . They are particularly suited to understanding the brain disordered by saying down information (prior probability) wrong by improper memory of the traumatic event. The confrontation of these descending information and perceived bottom-information could be partly responsible for the symptoms of PTSD.

Once validated, the model will characterize the individual level the most at risk of unfavorable patients (calculating a probability of developing PTSD) and to assess the epidemiological impact on long-term cohort of event considered.

These determinations are necessary prerequisites to optimize the means of support for these current and future casualties.

The investigators main objective is to define a Bayesian model describing a resilient functioning facing a trauma which also allows to describe a possible evolution of the ASD to PTSD by an error.

The state of PTSD or not will be determined by the PCL-S scale.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
