Prevalence and Predictors of Suicide Ideation among Elderly Mentally Ill Population in a Tertiary Psychiatric Hospital

BACKGROUND Suicide attempts in elderly people has higher risk of mortality. The elderly are more vulnerable to depression and other psychological and social factors that may contribute to higher risk of suicide. Studies have suggested that suicide in elderly is strongly associated with depression and lack of social support. Factors that increase risk of suicide are also found to increase the risk for suicide ideation. Suicide ideation is an important predictor of suicide attempts and completed suicide. Aims: Our study aims at estimating the prevalence of suicide ideation among mentally ill geriatric population and identifying potential predictors of suicide ideation among elderly. METHODS A cross-sectional study involving 50 persons with mental illness aged above 60 years and 50 persons with no previous psychiatric history. The was conducted at a tertiary psychiatric hospital. Geriatric Suicide Ideation Scale, Geriatric Depression scale and other psychopathology assessment tools were used. RESULTS The GSIS scores were significantly higher among those elderly persons with mental illness and the scores were higher in our study when compared to the community-dwelling elderly persons without psychiatric illness. It was observed that geriatric depression was an important predictor of suicide ideation followed by previous suicide attempt. The study also finds significant difference in the subscales of GSIS and we constructed an ROC for optimal cut-off point for the Indian population. CONCLUSIONS Geriatric suicide ideation is a less studied area with suicide ideation in elderly person with mental illness having various determinants and risk factors. It is for further research to identify feasible means of assessing suicide ideation among the elderly person receiving care from primary care physicians.
