Up to 79% of people who die by suicide will die on their first attempt. This stark reality makes immediately clear the importance of effective early detection and intervention. At the same time, approximately half of all people who die by suicide denied any suicidal ideation or behaviors at their last care encounter, and are identified as “low risk.” Despite the numerous advancements in health care over the last forty years, our ability to accurately predict suicide has not improved.
An original investigation published in JAMA Psychiatry earlier this year analyzed 306,800 suicide decedents from 2003-2020 for insights into risk factors, circumstances of death, toxicology, and method. They found five distinct profiles: (1) comorbid mental health problems and substance use, (2) mental health problems without substance use, (3) crisis, alcohol-related, and intimate-partner problems, (4) physical health problems, and (5) polysubstance use. From these five classes, the authors argue for tailored prevention strategies.
Class 4, decedents with physical health problems, was not only the largest cohort, but also the fastest growing, increasing over 30% since 2016. Significantly, this group had a strikingly low rate of diagnosed mental disorders and toxicology-detected psychotropic medication use (Just over 2% of individuals in this group had antidepressants present upon autopsy, compared with over 50% in class 1). They consulted non-mental health care professionals twice as often as mental health professionals in the 30 days prior to death. They were most likely to use firearms—a highly lethal choice of means: self-inflicted gunshot wounds are fatal in over 90% of cases versus drug overdoses, which are fatal only about 8% of the time.
This group highlights all too clearly the role primary care providers and non-mental health care providers can and must play in suicide prevention. MSHP has made a concerted effort to promote annual depression screening for all patients; this data highlights the significance of coordinated care for physical and mental health care, especially for patients living with chronic illnesses who may be at increased risk for suicidality.
