Background: Few studies have examined suicidal ideation and behavior in hospitalized physically ill elderly patients, a group potentially at high risk. Our aim was to investigate the prevalence and risk factors for suicide ideation, and direct and indirect self-destructive behaviors among a sample of elderly inpatients.

Methods: A cross-sectional study was conducted in 2009; 650 inpatients aged 60 years and over were screened from various medical services in teaching hospitals affiliated to Shiraz University of Medical Sciences in Iran. Suicidal ideation and behavior were measured with the Beck Scale for Suicidal Ideation (BSSI) and the Harmful Behavior Scale (HBS). Depression was measured with the Geriatric Depression Scale (GDS), medical burden with the geriatric version of the Cumulative Illness Rating Scale (CIRS-G), life events with the Paykel Life Event Scale, and social support with the Perceived Social Support Scale.

Result: Of the 650 patients screened with a mean age of 70.5 years (SD ± 7.5), 570 met inclusion criteria and of these 123 (21.6%) reported suicidal ideation on the BSSI and 80 (14.4%) had at least one self-destructive behavior included in the HBS. There was a significant correlation between suicide ideation and harmful behaviors (r = 0.503, p = 0.001). In a regression analysis, depressive symptoms, increased burden of medical conditions, marital status, history of substance use, history of traumatic life events, lack of perceived social support, and poor education were associated with both suicide ideation and harmful behavior. From demographic variables, living without a spouse and unemployment were predictors of suicidal ideation and behavior.

Conclusion: Hospitalized, physically ill elderly patients have high rates of suicidal ideation and self-destructive behavior and these vary according to psychosocial and clinical factors. The general hospital is therefore a potential site for the recognition of suicidal individuals and implementation of proximal suicide prevention strategies.

Objective: The aim of this study was to determine whether indirect self-destructive behaviors predict mortality in nursing home residents. Method: This cross-sectional study with follow-up after 2 years and 3 months surveyed 593 residents in 10 nursing homes in the eastern suburbs of Sydney, Australia. The following instruments were used: Harmful Behaviors Scale (HBS), Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), Functional Assessment Staging Scale, Resident Classificatin Index, Cumulative Illness Rating Scale, Even Briefer Assessment Scales for Depression, and the suicide item from the Structured Hamilton Depression Rating Scale. Diagnoses of depression, dementia, and psychosis were obtained from nursing home records. Mortality data were obtained in August 1999. Results: At follow-up, 297 (50.1%) residents were still alive with a mean survival time of 565.4 days. Survival analyses found that mortality was predicted by older age, male gender, lower level of functioning, lower levels of behavioral disturbance on the BEHAVE-AD, and higher scores on the HBS “passive self-harm” factor-based subscale, which includes refusal to eat, drink, or take medication. Discussion: These results suggest that passive self-harm behaviors predict mortality in nursing home residents.
