Core Tip

Core tip: The results of the present study suggest that the prevalence of suicidality in schizophrenic patients is high (19.6%). Females appear to have a slightly higher suicide risk than males, with borderline significance. Additionally, the factors related to higher levels of suicide risk were younger age, a current major depressive episode, receiving fluoxetine or lithium carbonate in the previous month, and a relatively higher score on the Charlson comorbidity index. Based on such findings, routine identification of suicidality, including suicidal ideation, suicide plans, suicide attempts, and monitoring and reducing the related factors should be beneficial in the management of inpatient schizophrenic patients.
