The aim of this study was to identify factors associated with suicide in patients with schizophrenia who required inpatient admission and to compare these factors with the risk profile of patients with other diagnoses also requiring inpatient care. A retrospective, matched case-control study of 51 patients with schizophrenia requiring psychiatric inpatient care was undertaken. A priori specified risk factors were investigated within the schizophrenia group and compared with those of patients with other psychiatric diagnoses. The results show that previous suicide attempts are associated with an increased risk of suicide across all diagnoses. The presence of depressive symptoms and involvement of police with the index admission become more significant factors in patients with schizophrenia, compared to those with other diagnoses. Supportive mental health accommodation is associated with a reduced risk of suicide. Suicide of individuals is difficult to predict in patients with schizophrenia. Young men appear particularly vulnerable at times of inpatient care. Depressive symptoms and previous suicide attempts are significant risk factors.
