Attempted suicide predicts suicide risk in mood disorders

Suicide risk was studied in a sample of 346 mood disorder inpatients, 92 of whom were admitted after a current suicide attempt. The overall suicide mortality after a mean observation period of 6 years was 8%. The potential of attempted suicide to predict suicide risk in hospitalized patients with mood disorders was studied by survival analysis after subgrouping on the basis of whether a current suicide attempt had occurred or not. The suicide risk the first year after attempting suicide was 12% (11/92), compared with 2% (4/254) in the mood disorder subgroup with no current suicide attempt. The long-range suicide risk after a current suicide attempt in depression was 15% (14/92) as compared with 5% (13/254) among those without a current suicide attempt. It is concluded that a current suicide attempt in mood disorder inpatients predicts suicide risk particularly within the first year and should be taken very seriously.
