Descriptive study of suicidal behavior in adult population attended in an emergency department during a one-year period and comparative study with the following annual period

Abstract

Introduction

Suicide is the most frequent psychiatric emergency. About 1% of all deaths are due to suicide so around 700,000 people commit suicide each year. Suicide attempt is more frequent in women (3:1) while completed suicide is more frequent in men (4:1). Most suicides occur in the 35-64 age range. The severity of a suicide attempt is assessed in terms of method, potential lethality, rescuability and impulsivity. A previous suicide attempt is the main risk factor for suicide behavior. The majority (more than 90%) of suicide behavior are related to an underlying psychopathology, mainly depression and substance abuse, especially alcohol. However, there are also numerous cases of impulsive attempts in the context of life stressors.

Objectives

To analyze sociodemographic and clinical characteristics of adult patients with suicidal behavior attended in the emergency department during a one-year period. To study the stability of the data obtained in the following annual period

Methods

A retrospective review of the population over 18 years attended in the emergency department during 2022 because of suicidal behavior, was carried out. Data collection for the year 2023 is in progress in order to be able to carry out a comparative study between both annual periods.

The age range between 18 and 25 years accounted for 28.5% of the total cases. The most frequent suicidal behavior was medication overdose with a total of 307 (54.6%), being more frequent in women than in men (2.6:1). The second most frequent reason for attention was suicidal ideation without suicide attempt, with a total of 212 patients (37.7%). 371 patients were discharged home from the emergency department (66%) and 191 required a longer observation in hospital environment. We are awaiting to complete data collection for 2023 to establish a comparison with those described above.
