Psychosocial and psychiatric characteristics of suicide completers with psychiatric treatment before death: a psychological autopsy study of 76 cases.

AIM: The present study was conducted to examine differences in psychosocial and psychiatric characteristics between suicide completers with and without a history of psychiatric treatment within the year before death, using a psychological autopsy method. METHODS: A semi-structured interview was administered by a psychiatrist and other mental health professionals for the closest bereaved of 76 suicide completers. RESULTS: Suicide completers with a history of psychiatric treatment (n = 38) were significantly younger than those without (n = 38) (P < 0.01), and a significantly higher proportion of cases in the treatment group were estimated to be suffering from schizophrenia. Further, in 57.9% of the treatment group, the fatal suicidal behavior involved overdose with prescribed psychotropic drugs. In addition, female suicide completers in the treatment group were more likely to have a history of self-harm or non-fatal suicidal behavior. CONCLUSION: Many suicide completers who received psychiatric treatment were young adults. It was common for suicide completers to overdose on prescribed drugs as a supplementary means of suicide, and many experienced self-harming behavior before death. In addition, a higher proportion of the treatment cases suffered from schizophrenia.

[State of suicide and effective efforts in suicide prevention in psychiatric hospitals and clinics].

Although factors related to suicide are complicated, mental health disorders are an important risk factor. It is anticipated that suicide prevention measures will be implemented from the perspective of improved psychiatric medicine. No national-scale study has been carried out in Japan on the state of psychiatric medicine and its influence on suicide since 2000. Moreover, many efforts not intended for suicide prevention have been shown to be effective for this purpose. Here, we conducted surveys to obtain basic data on suicide prevention and improvements in mental health care among 1,728 psychiatric hospitals and clinics in Japan in 2010. The incidence of suicide in psychiatric hospitals and clinics from January to December 2009 was estimated to be 100.5 for outpatients and 154.5 for inpatients per 100,000 patients. Regarding the duration from consultation to suicide, 87% of outpatients committed suicide less than one month following their last consultation. Moreover, approximately two-thirds of patients had undergone consultations for more than one year. A number of suicides in psychiatric hospitals and clinics occurred while patients were continuously undergoing treatment. Efforts shown to be effective in suicide prevention included risk assessment with multiple medical staff (i.e., doctors and nurses), a 24-hour crisis line, and a follow-up system for discontinued outpatients. We expect that the results of this survey will aid in the implementation of effective suicide prevention in psychiatric medicine.

Psychosocial and psychiatric aspects of suicide completers with unmanageable debt: a psychological autopsy study.

This study examined the psychosocial and psychiatric features of 16 Japanese suicide completers with unmanageable debt compared with 23 suicide completers without such debt at time of death, using a psychological autopsy method. The individuals with unmanageable debt were more likely to have been self-employed and to have experienced divorce. They were less likely to have engaged in help-seeking behavior, despite having mental health problems. Our findings suggest that providing comprehensive support and promoting help-seeking behavior may be important for suicide prevention in middle-aged men.

[Psychosocial classification of suicide completers by employment situation: a psychological autopsy study].

OBJECTIVE: This study sought to clarify psychosocial and psychiatric differences of suicide-completers dependent on their employment situation. METHODS: Since December 2007, we have been conducting a Japan-wide study on suicide-completers using a psychological autopsy method, a semi-structured interview by a psychiatrist and a mental health professional including a public health nurse with the closest bereaved. Items questioned included family environment, suicide situation, life history f, labor situation, economic problems, and psychiatric diagnosis according to DSM-IV criteria at the time of death. As of July 2009, we had collected psychosocial and psychiatric information for 46 Japanese suicide cases. RESULTS: More than half of 31 suicide-completers with a job at the time of their death were married men aged 40-59 (mean age 48.1 +/- 12.6). Many had social difficulties such as alcohol-related problems or debt (38.7% and 41.9%, respectively). More than sixty percent of the 15 unemployed suicide-completers were unmarried and aged 20-39 (mean age 43.4 +/- 19.9). The percentage of women in the unemployed suicide-completers was significantly higher than that for women with a job. Although social problems were not confirmed in the unemployed, the prevalence of alcohol use disorders was significantly higher in suicide-completers with ajob than in those who were unemployed. However, the prevalence of schizophrenia was significantly higher in the unemployed. CONCLUSIONS: Our findings suggest that to prevent suicide of those with ajob, enhanced mental health support in the workplace and a better understanding of the association between alcohol use disorders and suicide are required. To prevent suicide of those who are unemployed, mental health support for the younger generation, particularly in cases with schizophrenia, is recommended.

[Psychosocial features of suicide cases with alcohol problem: a psychological autopsy study].

AIMS: Alcohol use disorder is a well-known risk factor for suicide, as alcohol problems can deteriorate the medical and psychosocial conditions of individuals. Furthermore, the pharmacological effect of alcohol can cause impulsive behavior in individuals. However, few studies have investigated the association of alcohol problems with suicide in Japan. The purpose of the present study was to investigate psychosocial and psychiatric features of suicide-completers with alcohol problems in last one year before their death. METHODS: Since December 2007, we have been conducting a Japan-wide study on suicide-completers using a psychological autopsy method, a semi-structured interview by a psychiatrist and a mental health professional including a public health nurse with the closest bereaved. Items questioned included family environment, suicide situation, history of life, labor situation, economic problems, and psychiatric diagnosis according to DSM-IV criteria at the time of death. As of December 2009, we had collected psychosocial and psychiatric information about 76 Japanese suicide cases. RESULTS: 16 suicide-completers with alcohol problems ("Alcohol problem" group 21.1%) were all males and almost middle-aged workers. The percentages of debt and accident proneness in "Alcohol problem" group were significantly higher than "Non-alcohol problem" group. In "Alcohol problem group", none of them have had treatment of alcohol dependence. The prevalence of alcohol use disorders in "Alcohol problem group" was significantly higher than in "Nonalcohol problem" group (81.2% vs. 0%). CONCLUSION: The findings of the present study suggest that it is important to improvement of psychiatric care in alcohol dependence for prevention future suicides among alcoholics. Furthermore, enlightenment the association between alcohol problems and suicide to the public and medical doctors is required.

Comparing the acid-suppressive effects of three brands of generic lansoprazole with the original: pharmacokinetic bioequivalence tests do not necessarily guarantee pharmacodynamic equivalence.

Generic drugs contain the same active ingredient as an original drug and have their bioequivalence proved by pharmacokinetic tests. However, few studies have been reported on whether these bioequivalence studies infer pharmacodynamic equivalence. In this study, in eight healthy Helicobacter pylori-negative CYP2C19 extensive metabolizers, we compared the acid-suppressive effects of repeated administration of 15 mg of three brands of generic lansoprazole, Taiproton, Tapizol, and Lansoral, with those of the original lansoprazole, Takepron. Median intragastric pH value for 24-h and % pH > 4 for daytime (08:00-20:00 h) and night-time were significantly higher with any lansoprazole formulation, compared with the control (P < 0.05, Wilcoxon signed-rank test). However, during the daytime, % pH > 4 with Tapizol was significantly lower than the original (P < 0.05). Compared with the original, no significantly larger, but no small range of inter-subject variations were observed in these two parameters for each of the three brands of generic lansoprazole (Bartlett test). Pharmacokinetic bioequivalence tests do not necessarily guarantee pharmacodynamic equivalence.

Mental disorders and suicide in Japan: a nation-wide psychological autopsy case-control study.

BACKGROUND: The purpose of the present nationwide psychological autopsy case-control study is to identify the association between mental disorders and suicide in Japan, adjusting for physical conditions. METHODS: A semi-structured interview was conducted of the closest family members of 49 suicide completers and 145 gender-, age-, and municipality-matched living controls. The interview included sections of socio-demographic characteristics, physical conditions, and a psychiatric interview producing DSM-IV diagnoses of mental disorders prior to suicide (or at survey). We compared prevalences of mental disorders between the two groups, using conditional logistic regression. RESULTS: A significantly higher proportion with any mental disorder was found in the suicide group (65.3%) compared to the control group (4.8%) (p=0.003, odds ratio [OR]=7.5). The population attributable risk proportion associated with mental disorder was 0.24. Mood disorder, particularly major depressive disorder, was the most strongly associated with suicide (p<0.001). Anxiety disorder, alcohol-related disorder, and brief psychotic disorder were also significantly associated with suicide (p<0.05). These patterns were unchanged after adjusting for serious chronic physical conditions. LIMITATIONS: The present study had some limitations, such as small sample size, sampling bias and information bias. CONCLUSIONS: Most mental disorders, particularly mood disorder, were significantly associated with a greater risk of suicide in Japan, independent of physical conditions. Mental disorders are a major target of suicide prevention programs in Japan.
