P059: Characteristics of older adults attending the emergency department for suicidal thoughts or voluntary intoxication: a multicenter retrospective cohort study

Abstract

Introduction: Suicidal thoughts and self-harm are disproportionately prevalent among older adults but are frequently overlooked by emergency physicians. Objective: This study aims to explore the characteristics of older adults visiting the ED for suicidal thoughts or voluntary intoxications. Methods: All older adults (□ 65 years old) who visited one of the five CHU de Quebec’ EDs in 2016 were eligible. The medical charts of patients who reported suicidal thoughts or intoxication in triage or received a relevant discharge diagnosis were reviewed. Involuntary intoxications were excluded. Descriptive statistics were used to present the results. Results: Results: A total of 478 ED visits were identified, of which 332 ED visits (n= 279 patients) were included. The mean age of the ED cohort was 72.6 (standard deviation 6.8) years old and 41.6% were female. Mood disorders (41.2%) and alcoholism (40.5%) were common. Most included patients had a diagnosis of voluntary intoxication (73.2%), including two suicides (0.6%). Following 109 ED visits (30.0%), patients were referred for a mental health assessment. Half of all ED visits resulted in a discharge by the emergency physician (50.0%), while 27.4% were admitted for in-patient care. In the subsequent year (2017), 38.4% returned to the ED for suicidal ideations or self-harm of which 7.9% attended the ED □ 5 times. Conclusion: ED visits for suicidal thoughts and voluntary intoxication in older adults are more common among men with known mood disorders or alcoholism. Referral for a mental health assessment is inconsistent. ED-initiated interventions designed for this population are needed.
