Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The methodology will compare the episodic memory results of patients admitted for IMV who have exclusively ingested amnesic substances to a subject control group that has made IMV with non-amnesic substances such as paracetamol. The purpose of this comparison is to ensure that memory problems are not related to the context of the suicidal crisis.

The second step will be able to relate the memory score of the predictor variables. To achieve this, it will perform a multivariate linear regression in each group in order to confirm the results of the pilot study and to be able to regress in the control group which was not possible in the pilot study because of the lack of effective.

Finally, this study will try to establish, using Receiver Operating Characteristic (ROC) curves, thresholds for cognitive scores and begin to develop a tool for clinical practice.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: A group using amnesic substances

A group of patients admitted for IMV exclusively using amnesic substances. Benzodiazepines, benzodiazepines, tricyclic antidepressants, neuroleptics, antihistamines, other atropine substances, anti-epileptics and opiates.

Two visits for evaluation, the first one for the first evaluation of cognitive functions directly following the psychiatric interview, and the second one at 24h-48h of the psychiatric evaluation (T2), a second evaluation (E2) will take place.
Behavioral: Two visits for evaluation

Visit 1:The first evaluation (E1) of cognitive functions will take place directly following the psychiatric interview (T1), in order to better reflect the cognitive abilities at the time of the proposal of the care project.

This will include the Memory Functioning Questionnaire (MFQ), the five words of DUBOIS, the TMT-A and B, the WAIS code test, and the BADDELEY door test. An intercurrent type ringing event of the phone will take place during this evaluation.

Visit 2: At 24h-48h of the psychiatric evaluation (T2), a second evaluation (E2) will take place.

An episodic memory score will be determined by asking the patient to recall,as precisely as possible the evaluation E1. At first the reminder will be free,the data can be completed, if necessary, with an indication, a recognition.
ACTIVE_COMPARATOR: A control group

A control group that ingested exclusively non-amnesic substances among them most frequently ingested in this context, ie the following classes: level 1 analgesics, antibiotics, serotonergic and noradrenergic antidepressants, oral antidiabetic, thyroid hormones, anti oral coagulant.

Two visits for evaluation, the first one for the first evaluation of cognitive functions directly following the psychiatric interview, and the second one at 24h-48h of the psychiatric evaluation (T2), a second evaluation (E2) will take place.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Evaluation of the episodic score recall of the first interview (T1) at T2
Time Frame: Just After/24-48h after the psychiatric interview

This score is based on the episodic scale. The episodic score is a reflection of the patient's memory of the emergency psychiatric assessment. In this study, this score will be used as a variable independent of the multivariate linear regression, the objective of the study being to identify the variables significantly related to this score.

The total episodicity score is calculated by adding the episodic scores of several events. A continuous score is obtained and between 0 and 38.
Just After/24-48h after the psychiatric interview

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Comparison of cognitive scores between the amnesic substances group and the control group using the The Memory Functioning Questionnaire (MFQ) abridged version of tthe Memory Functioning Questionnaire
Time Frame: Just After/24-48h after the psychiatric interview
The control group is a group of subject having made an IMV with non-amnesic substances such as paracetamol.
Just After/24-48h after the psychiatric interview
