Poor access to mental health services linked to suicide hotspots

Communities with poor access to mental health services are eight times more likely to be youth suicide "hotspots," according to new Telethon Kids Institute research.

In a paper published today in the Australian & New Zealand Journal of Psychiatry, researchers used national coronial data to map suicides of 1,959 young people aged 10–24 who died between 2016 and 2020.

Led by prevention researcher Dr. Nicole Hill, the team identified eight suicide "hotspots" in large swathes of remote and regional Western Australia and Queensland, as well as parts of country New South Wales and South Australia, where there were significantly more suicides than would be expected, and two "coldspots" in areas of metropolitan Perth and metropolitan Sydney where rates of suicide were far lower.

The team compared the characteristics of communities in these contrasting areas, including the number of and mental staff available, opening times, and to services at the time young people were in a state of acute suicidal crisis and died by suicide.

"This technique considered not just the number of services but how accessible they were to young people at the time of their death," Dr. Hill said.

The findings showed that hotspot communities had substantially lower access to mental health services compared to coldspot communities.

"Specifically, we found areas with low mental health workforce supply were associated with eightfold greater odds of a suicide occurring in a hotspot compared to non-cluster suicides," Dr. Hill said.

"The suicide coldspots we identified all occurred in areas characterized by moderate-to-high mental health workforce supply."

In addition to access to mental health services, illicit substance use among young people at their time of death was 20% higher in hotspot communities.

"It's a known problem that people who have substance misuse problems are often not eligible to access mental health services. This is a real missed opportunity for youth suicide prevention and the prevention of suicide clusters," Dr. Hill said.

By comparing hotspots with coldspots the researchers were able to not only establish the link between higher suicide rates and lower access to services, but that high access to mental health services may be a protective factor against suicide in .

"These findings have important implications for postvention and the prevention of suicide contagion, where a cluster of can follow the suicide of someone within a community," Dr. Hill said.

"When a young person dies by suicide, there is often a lot of fear and anxiety about the prospect of further deaths in the community. This research suggests that providing timely access to mental health services, particularly in the aftermath of a suicide, may potentially be protective against further deaths."

Dr. Hill said the paper represented the first controlled study where researchers had been able to show a strong link between service access and higher or lower suicide rates.

"It's really the first time we have been able to identify a modifiable risk factor because we can't make a community less remote, but we can improve access to services in that community," she said. "It's an empowering message: there is something we can actually do about it.

"It also points to an important message around postvention and the prevention of suicide clusters, that in the aftermath of suicide the community should assess factors that may impact help-seeking—such as current waitlist times to mental health services—because if those supports aren't in place there could be the risk of further deaths.

"We can't just be telling people to seek help when a suicide occurs, because if that help isn't available we are potentially increasing helplessness and putting that community at greater risk."

Dr. Hill said the findings also highlighted the risks associated with rapid development, where there can be a significant lag in health infrastructure and mental health support services.

"WA has the nation's highest population growth following COVID-19. This paper shows that we need to have mental health services scaled up to accommodate the increased demand for services."
