Suicidal Ideation is Associated With All-Cause Mortality.
Suicidal ideation may be associated with all-cause mortality. Available research shows that treatment of depression reduces the risk of all-cause mortality in patients with suicidal ideation. However, this finding has not been replicated in a clinical population, where patients have various mental health conditions. We examined the association between suicidal ideation and all-cause mortality in a clinical cohort. We stratified patients presenting to a mental health clinic from January 2005 through December 2007 based upon their degree of suicidal ideation and obtained vital status information through June 2015. We compared groups using survival analysis, adjusting for patient characteristics and treatment receipt. Among 1,869 patients who completed the initial assessment, there were 363 deaths. Patients with the highest levels of suicidal ideation died at increased rates. Cause-of-death data in the year following the initial assessment indicates that the difference in mortality is not likely attributable to suicide. Accounting for patient characteristics and treatment, which included medical care and mental health care, did not meaningfully diminish the relationship between suicidal ideation and all-cause mortality. Additional research is needed to determine specific treatment elements that may moderate the relationship between suicidal ideation and all-cause mortality.
