Suicide configures failure in the mental health care of persons deprived of their liberty in terms of detection of risk factors, prevention, specific planning in terms of addressing thoughts of death or autolytic planning, trends, impulses and moods. The factors that unite in this catastrophe are multiple and depend not only on mental health care, but also on the circumstances that led to the deprivation of liberty, the family and the care of social continence and the intimate relationship of the person with its existence. Also, security personnel who take care of people in confinement contexts have a preponderant role in suicide preference. Structuring the personality distorted, immature or insufficient, circumstances that lead to vulnerability and threaten the preservation of life in the context of constant stress and loneliness. The transdisciplinary work experience provides us with constant review and dynamic concepts and practices to predict, diagnose and prevent risky behaviors prone to the symptoms of self-injury or self-harm of patients. In this sense, we propose interdisciplinary interviews of entry, registry for the detection of risk factors, specific treatment in patients at risk. The transdisciplinary confluence is a tool to be implemented to quantify the results and propose to reduce the incidence of suicide in people in a confinement context.
