A false sense of security: Rapid improvement as a red flag for death by suicide

Postdischarge from inpatient psychiatry is the highest risk period for suicide, thus better understanding the predictors of death by suicide during this time is critical for improving mortality rates after inpatient psychiatric treatment. As such, we sought to determine whether there were predictable patterns in suicide ideation in hospitalized psychiatric patients.

We examined a sample of 2,970 adult's ages 18-87 admitted to an extended length of stay (LOS) inpatient psychiatric hospital. We used group-based trajectory modeling via the SAS macro PROC TRAJ to quantitatively determine four suicide ideation groups: nonresponders (i.e., high suicide ideation throughout treatment), responders (i.e., steady improvement in suicide ideation across treatment), resolvers (i.e., rapid improvement in suicide ideation across treatment), and no-suicide ideation (i.e., never significant suicide ideation in treatment). Next, we compared groups to clinical and suicide-specific outcomes, including death by suicide.

Resolvers were the most likely to die by suicide postdischarge relative to all other suicide ideation groups. Resolvers also demonstrated significant improvement in all clinical outcomes from admission to discharge.

There are essential inpatient psychiatry clinical implications from this work, including that clinical providers should not be lulled into a false sense of security when hospitalized adults rapidly improve in terms of suicide ideation. Instead, inpatient psychiatric treatment teams should increase caution regarding the patient's risk level and postdischarge treatment planning.
