Suicidal Attempts and Ideation Among Children and Adolescents in US Emergency Departments, 2007-2015

In the United States, suicide is a major public health concern and the second leading cause of death among youths age 10 to 18 years, persisting into early adulthood.1 Attempted suicide is the strongest predictor of subsequent death by suicide,2 and many children with suicide attempts (SA) and suicidal ideation (SI) first present to an emergency department (ED).3 Recent evidence has demonstrated marked increases in SA/SI among children and adolescents presenting to US tertiary children’s hospital EDs.4 Using a nationally representative data set, we tested the hypothesis that rising ED visits for pediatric SA/SI would be observed nationwide in a broad, generalizable sample.

We performed a repeated cross-sectional analysis of the National Hospital Ambulatory Medical Care Survey (NHAMCS) ED database from 2007 to 2015. NHAMCS data are a nationally representative sample collected annually by the US Centers for Disease Control and Prevention’s National Center for Health Statistics. The survey samples approximately 30 000 visits to 300 randomly selected US EDs using multistage probability sampling to allow for the generation of US population-level estimates.5 The study population included all children younger than 18 years and the primary outcome was children aged 5 to younger than 18 years with a chief complaint or discharge diagnosis of SA or SI, which was identified by the NHAMCS reason-for-visit code (5820, 5820.0) and International Classification of Diseases, Ninth Revision, Clinical Modification (E950.0-E958, V62.84) codes.4 This study was exempted from review by the McGill University Health Centre research ethics board, and patient consent was not required because the data were from a publicly available database operated by the US Centers for Disease Control and Prevention. Survey-weighting procedures were applied to account for the sampling design. Trends were evaluated using a weighted Pearson χ2 test of proportions (Stata, version 14.1; StataCorp). A 2-tailed P value of <.05 was considered statistically significant.

Over the 9-year study period, there were 59 921 unweighted ED visits for children younger than 18 years in the NHAMCS, among which 1613 (2.8%; 95% CI, 2.5%-3.0%; range, 161-198 observations annually) met the inclusion criteria for SA/SI visits. The median age was 13 years (interquartile range, 8-15 years). Most were evaluated in nonteaching and nonpediatric hospitals (Table). Notably, 43.1% of SA/SI visits were for children aged 5 to younger than 11 years and only 2.1% were hospitalized. The estimated annual visits for SA/SI between 2007 and 2015 (Figure) increased from 580 000 to 1.12 million (92.1%; 95% CI, 68.9%-130.3%; P for trend = .004). Conversely, there was no statistically significant change in total ED visits during this time (26.9 million to 31.8 million; 18.2%; 95% CI, −5.4% to 42.2%; P for trend = .67). As a proportion of all pediatric ED encounters, SA/SI increased from 2.17% (95% CI, 1.82%-2.58%) in 2007 to 3.50% (95% CI, 2.79%-4.39%) in 2015 (61% increase; P for trend < .001). Emergency department visits for SA only similarly increased from 540 000 to 960 000 (79.3%; 95% CI, 62.2%-137.8%; P for trend = .02).

This analysis of a large, nationwide sample demonstrated that ED visits for SA/SI doubled among youth between 2007 and 2015. These findings parallel a 2-fold increase in SA/SI visits to US tertiary children’s hospitals over the same period.4 An earlier NHAMCS analysis reported a doubling in ED visits for suicidal behavior in all age categories between 1993 and 2008,6 reflecting an apparent acceleration of pediatric suicide-associated visits to US EDs. Findings suggest a critical need to augment community mental health resources, ED physician preparedness, and post–emergency department risk reduction initiatives to decrease the burden of suicide among children.

A strength of the NHAMCS is its inclusion of hospitals other than academic centers, which are the settings for most published research, thereby giving a more complete picture of health care trends.5 In this broader setting, NHAMCS data suggest more at-risk young children than described among pediatric hospitals alone. Moreover, NHAMCS population-level estimates highlight the magnitude of this trend (7.3 million pediatric SA/SI visits over 9 years).

Among the study limitations, it is possible that nonsuicidal self-harm was incorrectly coded by physicians as SA/SI. The NHAMCS validation processes minimize data misclassification5; however, coding processes may miss cases in which suicidal intent was not elicited, possibly underestimating SA/SI visits. We analyzed SA/SI together4; however, SA and SI are different behaviors and likely exist along a spectrum for the risk of future death by suicide. The analysis that was restricted to SA alone revealed a similar trend. No conclusions can be drawn regarding the cause for the observed increase, which is likely multifactorial. We studied only ED visits and not office-based encounters.

Ive been working at a psychiatric center for a few months now and I am absolutely startled by the amount of children that come in with a suicide attempt. Most kids, it's either sexual abuse or bullying. There are others too, or kids on the unit with different reasons for being there... But I would say at any given time, 80-90% of my kids are on sexual victim precautions. It breaks my heart.

A record amount of young people are becoming more and more unsocial.

Its one of the most depressing statistics of the modern era.

Its the single biggest reason behind youth behavior changing so dramatically in the past decade, from having less sex, to drinking less, to doing less drugs etc. It isn't because they are making better decisions, its because they don't have many friends to do those things with, its because they don't socialize as much.

There is a massive loneliness epidemic among the youth right now, for both Gen Z and Millennials.

Edit: I just wanted to go a bit further into this topic. There are a few major reasons why, but one of the biggest ones is the rapid decline in big socialization spots for youth. Areas where you would go, and hang out with friends. Before social media, you couldn't very easily meet up with people, but there were certain spots you would go to where there were ALWAYS tons of young people hanging out, and eventually you met them and became friends with them by proxy of other friends. For me, this was a local field/basketball court I used to go to near my house, where there would be easily 50-100 people hanging out at any given time. I could always go there and meet up with people, make plans, find parties for the night etc. People would drink and smoke and hook up with each other there. There were easily a dozen places like this in my neighborhood. We even had names for them, there were 'cherry hill kids', which were teens and college kids who hung out in large groups near a staircase, and there were gazebo kids, who were a similar group who met at a big gazebo in the park nearby.

Those areas have mostly declined. You don't need a specific area to meet up with anyone anymore, you just contact them directly. Not to mention police crack down on those areas a lot nowadays. The rapid decline in these areas seems to be one of the biggest reasons for the rapid decline in socialization in general. Now socialization is MUCH more insular and exclusive. You have to actually contact people directly to meet up with them, you cant just go to a spot and find them there.
