TOPLINE:
Emergency department (ED) visits in the United States for suicide attempts and intentional self-harm show an increasing trend from 2011 to 2020, with visits being most common among adolescents and the largest increase in visits being seen in adults aged 65 years or older.
METHODOLOGY:
- This study used data from the National Hospital Ambulatory Medical Care Survey, an annual nationwide cross-sectional survey, to track trends in ED visits for suicide attempts and intentional self-harm in the United States from 2011 to 2020.
- Researchers identified visits for suicide attempts and intentional self-harm, along with diagnoses of any co-occurring mental health conditions, using discharge diagnosis codes or reason-for-visit codes.
- The focus was to identify the percentages of ED visits for suicide attempts and intentional self-harm, with analyses done per 100,000 persons and for changes possibly linked to the COVID-19 pandemic in 2019-2020.
TAKEAWAY:
- The number of ED visits owing to suicide attempts and intentional self-harm increased from 1.43 million in 2011-2012 to 5.37 million in 2019-2020 (average annual percent change, 19.5%; 95% confidence interval, 16.9-22.2).
- The rate of ED visits for suicide attempts and intentional self-harm was higher among adolescents and young adults, particularly women, and lower among children.
- Despite a surge in ED visits for self-harm, less than 16% included a mental health evaluation, with visits among patients with mood disorders decreasing by 5.5% annually and those among patients with drug-related disorders increasing by 6.8% annually.
- In 2019-2020, those aged 15-20 years had the highest rate of ED visits (1552 visits per 100,000 persons), with a significant increase seen across all age groups; the largest increase was among those aged 65 years or older.
IN PRACTICE:
“Given that suicide attempts are the single greatest risk factor for suicide, evidence-based management of individuals presenting to emergency departments with suicide attempts and intentional self-harm is a critical component of comprehensive suicide prevention strategies,” the authors wrote.
SOURCE:
The investigation, led by Tanner J. Bommersbach, MD, MPH, Department of Psychiatry and Psychology, Mayo Clinic, Rochester, Minnesota, was published online in The American Journal of Psychiatry.
LIMITATIONS:
Visits for suicide attempts and intentional self-harm were identified based on discharge diagnostic and reason-for-visit codes, which may have led to an underestimation of visits for suicide attempts. ED visits for suicidal vs nonsuicidal self-injury could not be distinguished due to reliance on discharge diagnostic codes. Visits for suicidal ideation, which was not the focus of the study, may have been miscoded as suicide attempts and intentional self-harm.
DISCLOSURES:
No funding source was reported for the study. Some authors received funding grants from various institutions, and one author disclosed receiving honoraria for service as a review committee member and serving as a stakeholder/consultant and as an advisory committee member for some institutes and agencies.
