A Public Health Issue
If universal screening is not the answer to predicting and preventing suicide, what is? One way would be to approach suicide as a public health issue, Dr. Nestadt said.
“How did we reduce the rate of motor vehicle deaths? We didn’t test each driver’s reaction time behind the wheel,” he said. “Instead, we passed seatbelt and airbag legislation, implemented federal speed limits, and as a result, the number of motor vehicle fatalities decreased.”
Dr. Nestadt is an advocate for stronger gun safety legislation, which has proven effective in reducing suicide rates. A study published this year showed that states with child access prevention laws, negligent storage laws, and mandatory waiting periods for gun purchases reported fewer suicide deaths than those without that legislation.
Other measures might be applied in cases of extreme individual suicide risk, including extreme risk protection orders, also known as “red flag” laws, he added. This type of legislation provides a pathway for law enforcement to temporarily remove firearms from individuals who pose a risk to themselves or others.
“These have been shown to be very effective in saving lives,” Dr. Nestadt said.
Dr. Nestadt and others are also using machine learning models to predict suicide risk. Those identified as high-risk may be flagged on their electronic medical record. Ideally, when the algorithm becomes more accurate at predicting suicide, anyone treating this patient can then decide if action is needed, said Dr. Nestadt.
In his work with suicidal military personnel, Dr. Bryan and his colleagues established a brief form of cognitive behavioral therapy (BCBT) to help participants challenge cognitive distortions and build coping strategies to deal with feel with intense feelings of distress. Data show that BCBT reduced suicide attempts among active-duty soldiers by 60% compared with standard mental health treatment. It has since been shown to work in civilians as well.
Dr. Bryan is also researching fluctuations in the wish to live versus the wish to die relative to one another and mapping the trajectory of risk states along the way.
The goal is that these and other suicide prevention strategies currently under study by his team and others will help stem the rise in suicide deaths.
“Overall, we need to train mental health providers to implement suicide prevention therapies and establish suicide risk programs,” Dr. Bryan said. “But until we build one of these suicide prevention interventions to scale, we’re putting the cart before the horse.”
Dr. Roaten, Ms. Brummett, Dr. Bryan, and Dr. Nestadt reported no relevant disclosures.
