Study Finds Dramatic Increase in Ontario Teens Visiting ER for Self Harm

Canada Study Finds Dramatic Rise in Teen Self Harm

A new study published in the Canadian Journal of Psychiatry shows a dramatic increase in the number of Ontario teens who presented to an emergency department for self-harm between 2009 and 2017.

For the study, a team from the Children’s Hospital of Eastern Ontario Research Institute (CHEO) and the University of Ottawa (uOttawa) looked at all the emergency department visits by Ontario teens, ages 13 to 17, for self-harm or mental health concerns from 2003 to 2017: about 170,000 visits each year.

The researchers found that, between 2003 and 2009, the number of adolescents with a visit to the ED for self-harm fell by about a third. During the same period, ED visits for mental health stayed about the same.

Between 2009 and 2017, however, the rates of adolescent self-harm visits more than doubled. Likewise, the rates of visits for mental health problems rose by 78 percent. These increases were even greater among females.

“With the increased awareness in media and more generally about self-harm and mental health disorders, we wanted to see if there were any trends among adolescent emergency department visits in Ontario about these,” said Dr. William Gardner, senior scientist at the CHEO Research Institute, professor of epidemiology, uOttawa and senior research chair, child and adolescent psychiatry and lead author of the paper.

“What we found is that yes, incidents of self-harm are increasing, and so are ED visits with mental health concerns. But I don’t think any of the study team members expected such a dramatic rise from 2009 to 2017.”

There are approximately 840,000 adolescents aged 13 to 17 in Ontario, with 35 percent of them visiting an emergency department in any given year (140,000 or more). Of those visits, 5.6 percent have a mental health diagnostic code and 0.8 percent are for self-harm.

There are factors the authors believe warrant further research to shed light on the increases, including looking at current awareness campaigns about self-harm and mental health.

“Our data provide no evidence specifically but there were certain shifts that happened in 2009. The iPhone was introduced in 2007 and the use of smart phones has increased a lot since then. Engagement with social media could lead to increased rates of self-harm, at least for vulnerable adolescents,” said Gardner.

“This could happen in several ways: by normalizing self-harm, by triggering it, by getting teens to emulate self-harming peers, or by exposing youths to cyber-bullying. However, social media may also benefit some troubled adolescents. It can by provide them with a way to escape social isolation or find encouragement to seek treatment.”

Adolescents who intentionally harm themselves by poisoning or injuring themselves are at risk for repeated self-harm or suicide.

While emergency departments are often the first contact that many families have with the mental health system, the authors stress that these departments are not an ideal setting for delivery of mental health care for teens who have self-harmed or who are in crisis. Some emergency departments do not have clinicians who are trained to conduct mental health assessments.

“Community mental health follow-up after self-harm has been associated with reduced likelihood of repeat self-harm but evidence on whether youths can be successfully connected to mental health services from the emergency department is mixed,” said Gardner.

“What this study shows is that many more youths who need mental health care are showing up in Ontario’s emergency departments. Unfortunately, the numbers of clinicians who can provide mental health care for adolescents hasn’t increased to meet the growing numbers of adolescents who need care. Sufficient treatment resources must be supplied to address increased demands for services.”
