Previous research has shown that suicide risk is highest in the year after people have been discharged from a psychiatric hospital. As such, identifying predictors of suicide within this time frame is important. Results from a systematic database search showed that all significant suicide predictors--those found in more than one study--could be grouped into factors related to suicidality, patient care factors, and demographic and psychopathological factors. Increased knowledge of suicide predictors for this particularly high-risk time, identified in this review, can help inform prevention and intervention efforts that may significantly reduce suicide rates.
