The objective of this study was to investigate the clinical features of suicide attempts in elderly patients (Ն65 years) in Japan. We enrolled 546 patients who attempted suicide and were hospitalized for inpatient treatment. Characteristics were compared between the elderly and non-elderly patients. Compared with the non-elderly group, the incidence of mood disorders was significantly higher and the average length of stay in the intensive care unit and the duration of hospitalization were significantly longer in the elderly group. Elderly patients hospitalized for attempted suicide were more likely to have mood disorders than the non-elderly.

The purpose of the present study was to provide preliminary data on the usefulness and safety of blonanserin for patients with delirium in the intensive care unit (ICU). The charts of 32 consecutive patients with delirium in the ICU were retrospectively reviewed. These patients were treated with blonanserin. A total of 96.6% had reduction in Memorial Delirium Assessment Scale score. The proportion of patients with side-effects was 24.1%. Blonanserin may be effective and safe in the treatment of delirium in the ICU.
