To investigate the rate of suicide in the 12 months after discharge from psychiatric hospital and to determine its relationship to age, diagnosis, and period.
Cohort study of patients discharged from psychiatric hospital.
Altogether 159,742 men and 178,271 women, aged 15-84, who were discharged from Scottish psychiatric hospitals during 1968-92.
During the 25 year period, 1212 male patients committed suicide in 198,059 person years at risk (612 per 100,000; 95% confidence interval (CI) 578,647) and 1099 female patients committed suicide in 228,993 person years at risk (480 per 100,000; 95% CI 452, 509). The overall standardised mortality ratio (general population rate = 1) was 27 (95% CI 26, 29) in men and 40 (95% CI 38, 43) in women. There were variations in the suicide rates in relation to age, diagnosis, and period. The ratio of the 1-28 day rate to the rate between days 29 and 365 over the whole study period was 1.7 (95% CI 1.4, 1.9) in men and 1.6 (95% CI 1.3, 1.8) in women.
The variations in the post discharge suicide rate by age, sex, diagnosis, geographical location, and period suggest that there are several risk factors which vary in their distribution. Further study of these may lead to the development of effective interventions.

    • "At the individual level, predictors of older adults' suicide were visit of emergency department, having been hospitalized, having a diagnosis of a mental disorder, using a psychoactive substance and being male which is consistent with prior studies (Awata et al., 2005; Beautrais, 2002; De Leo et al., 2013; Rurup et al., 2011). In fact, previous studies have indicated that the majority (85%) of individuals having died by suicide had sought services in the year prior to death (Geddes et al., 1979; Meehan et al., 2006; Powell et al., 2000). Others have also shown that 25 to 40% of suicide victims were in contact with psychiatric services in the year before death (Lowe et al., 1999; Pirkis and Burgess, 1998). "

    ABSTRACT: Objective: To determine the influence of individual and neighborhood characteristics associated with suicide in older adults. Method This study used two complementary data sources. The first used administrative data from the Quebec coroner’s office and included information on suicide deaths in older adults aged 65 years and over who died by suicide between 2000 and 2005 (n = 903 persons). The second data source, which was used to identify the control group, came from a longitudinal study on seniors’ health that was conducted in Quebec between 2004 and 2005 (n = 2 493 persons). Logistic regression analyses were used to test for associations between suicide and individual and neighborhood level characteristics. Results Suicide was associated with male gender, age, the presence of a physical and mental disorder and the use of health services. At the neighborhood level, suicide was associated with a higher population density, concentration of men, lower rates of education and higher rate of unemployment. Gender specific analyses also showed different patterns of associations on suicide risk. Conclusions Suicide in older adults is associated with neighborhood and individual characteristics. This suggests that policies targeting only one level of risk factors are less likely to significantly influence suicide among this population.

    ABSTRACT: The suicide risk of psychiatric patients fluctuated along the course of their illness and was found to be high in the immediate post-discharge period in some settings. The epidemiology and psychiatric services for the suicide population in Hong Kong have differed from those of the West (i.e., low youth suicide rate, high elderly suicide rate, high female/male ratio, and heavily government-subsidized psychiatric service). This study examined the suicide rates within a year of discharge from psychiatric inpatient care in Hong Kong. Discharges from all psychiatric hospitals or psychiatric wards in general hospitals in Hong Kong from 1997 through 1999 were followed up for suicides (ICD-9, E950-E959) and "undetermined" causes of deaths (E980-E989) by record linkage with the Coroner's Court until their deaths or Dec. 31, 2000. The suicide rates (/1000 person-years at risk) and standardized mortality ratios (SMRs; assigning a value of 1 to the same age- and sex-specific suicide rates in the general population) were calculated. 21,921 patients (aged over 15 years) were discharged from psychiatric hospitals from 1997 through 1999. Two hundred eighty patients committed suicide within 1 year of discharge; 85 suicides (30%) occurred within 28 days after discharge. The SMRs for suicide in the first 28 days after discharge were 178 (95% CI = 132 to 235) for females and 113 (95% CI = 86 to 147) for males. These rates were 4.0 (95% CI = 2.7 to 5.6) times higher for females and 4.6 (95% CI = 3.2 to 6.3) times higher for males than the rate in the rest of the year. Young adults had higher SMRs than the elderly. No specific diagnoses had higher suicidal risk than others. Calculations including undetermined causes of deaths (N = 53) gave similar results. The immediate post-discharge period carries a high risk of suicide for psychiatric patients. The high-risk groups are young adults and females. No diagnosis appears to carry a particularly high risk.

    ABSTRACT: Deinstitutionalization has been accompanied by a decreasing continuity of care in a number of countries. This study evaluates the effects of the Dutch model for deinstitutionalizing mental health care. Details of users and their use of community- and hospital-based services between 1990 and 1999 were retrieved from the Groningen case register. The time between discharge from the hospital and the first subsequent community-based contact was the primary indicator for changes in continuity of care. The total proportion of discharges from hospital-based mental health care followed within 6 months by community-based care increased by 11% due to the improved availability of day treatment and home treatment. In terms of median survival time, aftercare in the years 1998/1999 was delivered more than twice as fast as in the years 1990/1991. Study results supported the hypothesis in Dutch deinstitutionalization policy that the continuity of mental health care would benefit as to its longitudinal dimension.
