    ABSTRACT: Schizophrenia is characterized by high suicide risk and low awareness of disorder. Although awareness has benefits for medication compliance and clinical outcome, it is unclear how it may relate to suicide risk in this population. This multicenter investigation assessed awareness and suicide-related behavior in 980 patients with schizophrenia or schizoaffective disorder. Patients were followed over 2 years and assessed by blinded raters for suicide-related events. Awareness of psychiatric condition at baseline was associated with increased risk of suicide events over the follow-up. This effect was mediated by depression and hopelessness levels. By contrast, changes in awareness associated with treatment decreased the risk of suicide. Although some patients may become depressed after acknowledging the clinical handicaps of their disorder, treatment-related changes in awareness are generally associated with a positive outcome relative to suicide risk. The complex interactions and mediation effects of these clinical variables require careful monitoring.

    ABSTRACT: Approximately 50% of patients with schizophrenia or schizoaffective disorder attempt suicide, and approximately 10% die of suicide. Study results suggest that clozapine therapy significantly reduces suicidal behavior in these patients. A multicenter, randomized, international, 2-year study comparing the risk for suicidal behavior in patients treated with clozapine vs olanzapine was conducted in 980 patients with schizophrenia or schizoaffective disorder, 26.8% of whom were refractory to previous treatment, who were considered at high risk for suicide because of previous suicide attempts or current suicidal ideation. To equalize clinical contact across treatments, all patients were seen weekly for 6 months and then biweekly for 18 months. Subsequent to randomization, unmasked clinicians at each site could make any interventions necessary to prevent the occurrence of suicide attempts. Suicidal behavior was assessed at each visit. Primary end points included suicide attempts (including those that led to death), hospitalizations to prevent suicide, and a rating of "much worsening of suicidality" from baseline. Masked raters, including an independent suicide monitoring board, determined when end point criteria were achieved. Suicidal behavior was significantly less in patients treated with clozapine vs olanzapine (hazard ratio, 0.76; 95% confidence interval, 0.58-0.97; P =.03). Fewer clozapine-treated patients attempted suicide (34 vs 55; P =.03), required hospitalizations (82 vs 107; P =.05) or rescue interventions (118 vs 155; P =.01) to prevent suicide, or required concomitant treatment with antidepressants (221 vs 258; P =.01) or anxiolytics or soporifics (301 vs 331; P =.03). Overall, few of these high-risk patients died of suicide during the study (5 clozapine vs 3 olanzapine-treated patients; P =.73). Clozapine therapy demonstrated superiority to olanzapine therapy in preventing suicide attempts in patients with schizophrenia and schizoaffective disorder at high risk for suicide. Use of clozapine in this population should lead to a significant reduction in suicidal behavior.
