Health care contacts before and after attempted suicide among adolescent and young adult versus older suicide attempters

BACKGROUND: The pattern of all health care contacts among young people before and after attempted suicide is not well documented. Neither is it known if the health care contacts of young suicide attempters differ from those of older suicide attempters. This study investigated the age-related clinical characteristics of suicide attempters and the pattern of their contacts with health care before and after attempted suicide in different age groups, particularly adolescence and young adulthood. METHOD: All consecutive 1198 suicide attempters treated in hospital emergency rooms in Helsinki between January 1997 and January 1998 were identified and divided into three age groups (15-24 years, 25-39 years, 40 years and over). Data were gathered on all health care contacts 1 year before and after the index attempt. RESULTS: Although adolescent and young adult suicide attempters suffered from severe mental disorders, a remarkable proportion of them were left without psychiatric consultation and aftercare recommendation following the attempt. Two-thirds of 15-19-year-old male suicide attempters had no treatment contact during the month before the attempt, while a quarter of them were referred to psychiatric consultation and a half had no healthcare contact in the month following the attempt. CONCLUSIONS: These findings indicate considerable scope for improvement in the assessment of young suicide attempters and their referral to aftercare.     

Suicide and attempted suicide among older adults in Western Australia

BACKGROUND: Suicide rates are high in later life. Risk factors include male sex and depressive illness. This study investigated the relationship between suicidal behaviour and contact with mental health services among the elderly in Western Australia. METHODS: Record linkage was used to obtain records of hospital admissions and mental health service contacts for all suicide attempts and deaths in the period 1980-95. Standardized incidence ratios were calculated for the elderly, general population and people with mental health service contacts. Cox regression was used to evaluated potential risk factors for elderly people who were in contact with mental health services. RESULTS: People over 60 years of age accounted for 15% of suicides and 4.6% of attempted suicides. Suicide rates were 3.3 times higher in males and 4.4 times higher in females when compared to the general population of elderly people. For attempted suicide, the rate was 5.8 times higher in males and 6.6 times higher in females with prior contact with mental health services. Highest risk of suicide was found in patients with diagnoses of affective psychoses (RR = 3.7), adjustment reaction (RR = 3.2) or depressive disorder (RR = 2.8). The diagnosis of cancer was associated with decreased risk of suicide (RR = 3.6) and attempted suicide (RR = 1.9). CONCLUSIONS: Suicide rates are high among the elderly in Western Australia. Suicide is significantly associated with the diagnosis of mood disorder. Suicide attempts are less common, and are associated most strongly with mood and personality disorders. The decreased risk of self-harm behaviour among patients with cancer warrants further investigation.     

Comparison of the clinical features of suicide attempters by jumping from a height and those by self-stabbing in Japan

Background

A history of psychiatric disorders is a high risk for suicide. The present study compared the clinical features of psychiatric patients in Japan who attempted suicide by jumping from a height and those who attempted suicide by self-stabbing.

Methods

We compared two groups of suicide attempters who were hospitalized for both physical and psychiatric treatment (n=202). We compared the psychiatric diagnoses and clinical features between those who attempted suicide by jumping from a height (N=147) and those who did so by self-stabbing (N=55).

Results

The self-stabbing group (mean age 52.3 years) was significantly older compared to the jumping group (mean age 37.9 years). A significantly higher proportion of females were found in the jumping group. Jumping from a height was significantly associated with schizophrenia spectrum disorders, whereas self-stabbing was significantly associated with mood disorders.

Limitations

The results were drawn from data from a single hospital in a large urban city, and the study population did not include subjects who completed their suicide attempts.

Conclusions

Our findings show that differences in suicide methods (here, between jumping from a height and self-stabbing) may be related to suicide attempters' psychiatric diagnosis, gender and age. It is thus important to obtain a more detailed background information about a patient's suicide attempt and to create suicide prevention plans in accord with individuals' psychiatric diagnosis, age and gender, especially among those who have attempted suicide by jumping from a height or self-stabbing.     

广州市精神病医院50年住院病人自杀危险因素的病例对照研究

目的:识别精神分裂症住院病人自杀的潜在危险因素,为探讨如何进一步预防住院精神病人的自杀提供依据。方法:对广州市精神病医院1956-2005年住院精神病人自杀进行回顾性分析,并对其中的精神分裂症病人按同性别、同诊断、相同或相近年龄、住院进行1:1匹配的病例对照研究。结果:共有77例住院精神病人发生自杀,自杀发生率为133.1/10万(95%CI103.4-162.85/10万)。多数自杀者为精神分裂症病人(64例,占83.1%),多数自杀者采取自缢的方式(59例,占76.6%),多数病人的自杀行为发生在病房内(52例,占67.5%);自杀组的住院次数明显高于对照组(2.13±1.89/1.23±0.75,P=0.001);自杀组本次住院前1月及住院期间的自杀未遂次数明显高于对照组(0.39±0.85/0.09±0.39,0.59±1.52/0.00±0.00,P=0.017,0.003)。自杀组有罪恶观念、心境抑郁者多于对照组(18.8%/3.1%,28.1%/6.3%,P=0.006,0.004);住院精神分裂症病人的罪恶观念、心境抑郁、本次住院前1月有自杀意念和自杀未遂是其自杀行为发生的危险因素(β=2.407、1.566、1.201、1.643)。结论:该院50年住院病人的自杀发生率与国外近似,精神分裂症病人自杀的危险因素是罪恶观念、心境抑郁、住院前1月自杀意念和自杀未遂。     

Incidence of suicide ideation and attempts in adults: the 13-year follow-up of a community sample in Baltimore, Maryland.

BACKGROUND: Utilizing a prospectively designed community sample, we set out to estimate the rate of newly-incident suicidal ideation and attempts (non-fatal suicide behaviour) in a community sample, to evaluate antecedent sociodemographic characteristics and psychiatric disorders, and to assess use of mental health services in relation to non-fatal suicide behaviour. METHOD: Prospectively-gathered data was utilized from 3481 continuing participants in the 13-year follow-up of the Baltimore sample of the NIMH Epidemiologic Catchment Area survey interviewed in 1981, 1982 and 1993/6. RESULTS: The incidence of suicide attempts was estimated at 148.8 per 100,000 person-years and ideation at 419.9 per 100,000 person-years. Persons in the youngest age group, in the lowest socioeconomic status, and previously married persons were at increased risk for non-fatal suicide behaviour during the follow-up interval. Persons who reported suicidal ideation at baseline were more likely to report having attempted suicide at follow-up (RR = 6.09, 95% CI 2.58-14.36). Psychiatric disorders, especially depression and substance abuse, were associated with new-onset of non-fatal suicidal behaviour. While persons who reported newly-incident suicidal behaviour were more likely to report use of mental health services, few said that suicidal ideation or attempts were the reason for the visits. CONCLUSIONS: Suicidal ideation is a common and important antecedent to suicide attempts and deserves more attention in community and general medical settings.     

Suicidal behaviour among primary-care patients with depressive disorders

BACKGROUND: Most national suicide prevention strategies set improved detection and management of depression in primary health care into a central position. However, suicidal behaviour among primary-care patients with depressive disorders has been seldom investigated. METHOD: In the Vantaa Primary Care Depression Study, a total of 1119 primary-care patients in the City of Vantaa, Finland, aged 20 to 69 years, were screened for depression with the Primary Care Evaluation of Mental Disorders (PRIME-MD) questionnaire. Depressive disorders were diagnosed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), and the 137 patients with depressive disorder were included in the study. Suicidal behaviour was investigated cross-sectionally and retrospectively in three time-frames: current, current depressive episode, and lifetime. Current suicidal ideation was measured with the Scale for Suicidal Ideation (SSI), and previous ideation and suicide attempts were evaluated based on interviews plus medical and psychiatric records. RESULTS: Within their lifetimes, 37% (51/137) of the patients had seriously considered suicide and 17% (23/137) attempted it. Lifetime suicidal behaviour was independently and strongly predicted by psychiatric treatment history and co-morbid personality disorder, and suicidal behaviour within the current episode was predicted most effectively by severity of depression. CONCLUSIONS: Based on these findings and their convergence with studies of completed suicides, prevention of suicidal behaviour in primary care should probably focus more on high-risk subgroups of depressed patients, including those with moderate to severe major depressive disorder, personality disorder or a history of psychiatric care. Recognition of suicidal behaviour should be improved. The complex psychopathology of these patients in primary care needs to be considered in targeting preventive efforts.     

有无精神障碍自杀未遂者自杀强度和生活满意度的比较

目的：对有、无精神障碍自杀未遂者自杀强度及生活满意度进行比较。方法：对急诊室救治的自杀未遂者，由精神科医生使用调查表进行询问并做出精神障碍诊断，按有、无精神障碍分组，比较自杀强度和生活满意度。结果：调查自杀未遂者120例，有精神障碍39例，占32．5％。与无精神障碍自杀未遂组比较，有精神障碍组自杀强度高、生活满意度低；两组自杀未遂者均认为自杀当时的生活满意度最低，而离自杀行为的时间越远生活满意度越高。结论：有精神障碍的自杀未遂者自杀强度高、生活满意度低，这或许是精神病人出现较多自杀行为或有较高自杀死亡率原因之一。     

A note on suicidal deterioration with recovered memory treatment

BACKGROUND: Many patients who have been told they have Multiple Personality/Dissociative Identity Disorder (MPD/DID) seem to have deteriorated clinically after being so diagnosed. We report here the results of a survey of suicide attempts in patients diagnosed as having MPD and a comparison group hospitalized with a mood disorder. METHODS: Twenty individuals who had been diagnosed as having MPD, had developed false memories, and had relinquished them, were surveyed with respect to suicide attempts before and after the diagnosis. Twelve of those approached agreed to provide data and were compared with 12 patients from an in-patient mood disorders unit, matched for age and sex. RESULTS: In the MPD group more patients attempted suicide after being diagnosed than before and they made more separate attempts at suicide than before. The reverse was true in the comparison group with patients and suicide attempts before and after hospitalization. Comparing the numbers of attempts in the groups before diagnosis/hospitalization and afterward Chi(2)=20.177, DF=1, P<0.001. LIMITATIONS AND CONCLUSIONS: Both samples were highly selected, and the comparison group does not provide an exact control. Nevertheless, the results support a trend in the literature that finds the diagnosis of multiple personality disorder and the use of recovered memory treatment are harmful.     

Who receives the aftercare? Utilization of services by discharged in-patients

A prospective one-year follow-up of 216 in-patients showed that utilization of aftercare was significantly associated with certain clinical and social factors in the year after discharge from hospital. Rural domicile, a diagnosis of schizophrenia, long dependence on services, and ease of access to care comprised an aftercare dependency syndrome with substantial predictive power. Alcoholic and personality disordered patients were light users of services. Staff-patient relationships and attitudes of staff and patients to the need for aftercare were important. Depot neuroleptics were associated with high levels of aftercare for patients with chronic schizophrenia. The findings reveal the steady silting up of a new area service for the adult mentally ill by patients with a combination of social disadvantage and severe chronic psychosis. Family doctors played very little part in the delivery of aftercare. Some implications of the findings for the future development of community-based psychiatric services are discussed.     

Mortality among patients with schizophrenia and reduced psychiatric hospital care

BACKGROUND: There are suggestions that mortality, especially that due to suicide, increases among schizophrenia patients during a period of declining psychiatric beds. We investigated the mortality of schizophrenia patients in the general population of Finland during the reduction of psychiatric beds during 1980-1996. METHOD: Patients hospitalized for schizophrenia before 31 December 1996, and alive on 1 January 1980 (n = 58761) were identified via the National Hospital Discharge Register. General population data came from the National Population Register, and mortality data from the National Causes of Death Register. We calculated relative risks (RR) for total mortality, mortality due to natural causes (cancer, ischaemic heart disease, respiratory disease), unnatural causes (accident, homicide, suicide), and suicide. RESULTS: Patients with schizophrenia had an increased mortality both from natural causes (RR 2.59, 95% CI 2.55-2.63) and from suicide (RR 9.9, 95% CI 9.43-10.30). The RR for both natural and unnatural deaths was highest among patients with < 5 years since onset of schizophrenia. Among them all-cause mortality rose in the 1990s, but decreased among patients with > 10 years from onset. Otherwise no major changes or linear trends were found in mortality during deinstitutionalization. CONCLUSIONS: Reduction of psychiatric beds did not generally increase the mortality of patients with schizophrenia. However, patients in their early years of illness experienced increased mortality after the steepest bed reduction. Improved recognition and treatment of somatic illness would benefit patients with schizophrenia.     

Comprehensive analysis of the genes responsible for neuroacanthocytosis in mood disorder and schizophrenia

Neuroacanthocytosis syndromes are mainly comprised of two diseases: chorea-acanthocytosis (ChAc) and McLeod syndrome (MLS). There is a high incidence of psychiatric disorders such as mood disorder and schizophrenia among neuroacanthocytosis patients. We hypothesized that neuroacanthocytosis-related-genes might be associated with susceptibility to these psychiatric disorders. We performed a comprehensive mutation screen of VPS13A and XK, the gene responsible for ChAc and MLS, respectively, in 85 mood disorder subjects and XK in 86 schizophrenia subjects and compared the variants to 100 or more control alleles. We also performed copy number variation (CNV) analysis in 72 mood disorder subjects and 86 schizophrenia subjects. We identified three non-synonymous, two synonymous and six intron variants in mood disorder subjects and a novel GAT triplet repeat polymorphism in VPS13A. By CNV analysis, we identified a heterozygous exon 60-61 deletion in VPS13A in one mood disorder subject. We identified one non-synonymous and one intron variant in mood disorder and schizophrenia subjects, respectively, in XK. The presence of a pathogenic mutation or a potentially functional variant in mood disorder or schizophrenia subjects suggests that neuroacanthocytosis-related-genes might be involved in the pathogenesis of these psychiatric disorders.

Divalproex, lithium and suicide among Medicaid patients with bipolar disorder

BACKGROUND: Suicide completion and attempted suicide are major concerns for people with bipolar disorder. Studies in the private sector have suggested that lithium treatment may be superior to divalproex therapy with regard to minimizing suicidal behavior among individuals with bipolar disorder. However, few data are available regarding Medicaid patients diagnosed with bipolar disorder. METHODS: Subjects were 12,662 Oregon Medicaid patients diagnosed with bipolar disorder and treated with medication between 1998 and 2003. Outcomes measures were completed suicide and emergency department visits for suicide attempts (including non-fatal poisoning). Cox proportional hazards models were used to adjust for demographics, co-morbidity, and concurrent psychotropic medication use. RESULTS: Divalproex was the most common mood stabilizer (used by 33% of subjects) followed by gabapentin (32%), lithium (25%), and carbamazepine (3%). There were 11 suicide deaths and 79 attempts. Adjusted hazard ratios (versus lithium users) for suicide attempts were 2.7 for divalproex users (p<0.001), 1.6 for gabapentin users (not significant) and 2.8 for carbamazepine users (not significant). For suicide deaths, the adjusted hazard ratios were 1.5 for divalproex users (not significant), 2.6 for gabapentin users (p<0.001), and not available for carbamazepine users. LIMITATIONS: It should be noted that subjects were not assigned at random to medication use, data on prior suicide attempts were not available, medication use was measured by automated pharmacy records, and duration of mood stabilizer utilization may have been brief. CONCLUSIONS: Lithium may have a protective effect with regard to suicide attempts among Medicaid patients with bipolar disorder. It remains unclear whether or not lithium protects these patients against completed suicide.     

Prevention of suicide and attempted suicide in Denmark. Epidemiological studies of suicide and intervention studies in selected risk groups

The suicide rates in Denmark have been declining during the last two decades. The decline was relatively larger among women than among men. All age groups experienced a decline except the very young with stable rates and the very old with increasing rates. The Universal, Selective, Indicated (USI) model recommended by Institute of Medicine was used as a framework for the thesis. Universal preventive interventions are directed toward the entire population; selective interventions are directed toward individuals who are at greater risk for suicidal behaviour; and indicated preventions are targeted at individuals who have already begun self-destructive behaviour. At the universal level, a review was carried out to highlight the association between availability of methods for suicide and suicide rate. There were mostly studies of firearms, and the conclusion of the review was that there was clear indication of restricted access to lethal means was associated with decline in suicide with that specific method, and in many cases also with overall suicide mortality. Restricting access is especially important for methods with high case fatality rate. Our own study indicated a beneficial effect on suicide rates of restrictions in access to barbiturates, dextropropoxyphen, domestic gas and car exhaust with high content of carbon monoxide. Although a range of other factors in the society might also be of importance, it was concluded that restrictions in access to dangerous means for suicide were likely to play an important role in reducing suicide rates in Denmark, especially for women. At the selective level, there are several important risk groups such as psychiatric patients, persons with alcohol and drug abuse, persons with newly diagnosed severe physical illness, all who previously attempted suicide, and groups of homeless, institutionalized, prisoners and other socially excluded persons. The thesis focused on homeless persons and psychiatric patients, especially patients with schizophrenia and related disorders. The thesis contains a review of the risk of suicide in homeless. In all the studies included, increased suicide mortality was found, and in the studies that evaluated suicide risk in different age groups, the excess suicide mortality was most dominant in younger age groups. Our own study revealed an increased risk of suicide, and in univariate analysis, significant predictors for suicide were found to be associated with shortest stay in hostel less than 11 days and more than one stay during one year. The thesis also contains a review of the risk of suicide in first-episode patients with schizophrenia, and it was concluded on the basis of the identified studies that long-term risk of suicide was not 10 percent as previously accepted, but lower. Risk factors for suicide among patients with schizophrenia were evaluated in case control studies, in nested case control studies, and in prospective studies. The following risk factors were the most important and frequently observed predictors: male gender, young age, short duration of illness, many admissions during last year, current inpatient, short time since discharge, previous and recent suicide attempt, co-morbid depression, drug abuse, poor compliance with medication, poor adherence to treatment, high IQ, and suicidal ideations. The results of analyses of psychotic symptoms as risk factor for suicide were contradictory, but a recent meta-analysis concluded that both hallucinations and delusions seemed to be protective; however, there was a non-significant tendency that command hallucinations were associated with higher suicide risk. Prevention of suicide in schizophrenia must especially focus on improving assessment of risk of suicide during inpatient treatment and the first week after discharge, and special attention must be paid to patients with one or more of the identified risk factors. There is a need for large randomised clinical trials evaluating the effect on suicide and suicide attempt of psychosocial and pharmacological treatment in schizophrenia. In our own study, we did not find any effect of integrated treatment on attempted suicide, but there was an effect on hopelessness and a trend toward lower prevalence of depression among patients in the integrated treatment. There were four suicides and one probable suicide (drowning) in standard treatment and one suicide in integrated treatment at two-year follow-up, but the study did not have sufficient power to detect these differences in proportion to who committed suicide; more than one thousand patients should have been in each treatment condition in order for these differences in proportion to be significant. At the indicated prevention level, a literature review was carried out regarding risk of suicide attempt and suicide in short-term, medium-term and long-term follow-up of persons who attempted suicide. It was concluded that the risk of repetition in short- and medium-term follow-up studies was approximately 16 percent, with lower risk among "first-evers" compared to repeaters. There was a large variation in repetition rate. The proportion who committed suicide in medium-term follow-up studies was 2.8 percent and in long-term follow-up studies was 3.5 percent (weighted mean) with clearly higher proportions in the Nordic studies than in the studies from UK. Risk factors for attempted suicide were previous suicide attempt, alcohol and drug abuse, depression, schizophrenia, previous inpatient treatment, self-discharge before evaluation, sociopathy, unemployment, frequent change of address, hostility, and living alone. Several of the predictors are overlapping and most of them were already identified in early studies of factors predictive of repetition of suicide attempt. Predictors of suicide were male gender, increasing age, previous suicide attempt, serious suicide attempt, alcohol and substance abuse, somatic disease, mental illness, and planning of suicide attempt, high suicidal intent score, violent suicide attempt or suicide attempt with severe lethality, and ongoing or previous psychiatric treatment. In our follow-up study from Bispebjerg Hospital, we found that the risk of suicide during a ten-year follow-up period among patients admitted in 1980 after self-poisoning was 30 times greater than in the general population. We also found increased mortality by all other causes of death. Predictors of suicide were several previous suicide attempts, living alone and increasing age. There are not many randomised clinical trials of psychosocial interventions aiming to reduce risk of repetition among suicide attempters. A Cochrane review concluded that evidence was lacking to indicate the most effective forms of treatment for deliberate self-harm patients. A recent randomised controlled trial showed a positive influence of cognitive behavioural therapy on repetition rate. Our own quasi-experimental study of effectiveness of two weeks' inpatient treatment in a special unit of young persons who had severe suicidal thoughts or who had attempted suicide showed that risk of repetition was reduced in the intervention group, and that the intervention group obtained a significantly greater improvement in Beck's Depression Inventory, Hopelessness Scale, Rosenberg Self-Esteem Scale and CAGE-score. The study of emergency outreach indicates that there are many persons in the community that experience a suicidal crisis, and that this group is an important target group for psychiatric emergency outreach. In our study of registration and referral practice in Copenhagen Hospital Cooperation, we conclude that not all suicide attempts were registered as such in the National Patient Register - in fact, only 37 percent. It must be concluded that the quality of the Danish Patient Register must be improved with regard to registration of suicide attempt. We found that psychiatric evaluation was planned in relation to almost all suicide attempts, but that it must be recommended to pay attention to escorting patients to psychiatric emergency in order to ensure that the patient actually attends the planned consultation. We found that patients who were referred after psychiatric evaluation to psychiatric treatment at outpatient facilities only received the planned treatment in approximately two-thirds of the cases; therefore, like Hawton et al. [Hawton et al., 1998; Hawton et al., 1999], we recommend that outpatient facilities adopt an assertive approach to patients who have attempted suicide. Danish suicide research is strong, primarily due to the possibilities for linking complete national registers providing detailed data and large sample sizes for suicide research, which is so far unique for the Nordic countries. This, combined with skilful use of epidemiological methods, had resulted in a remarkable series of papers highlighting risk of suicide in different risk groups, risk factors and protective factors. This activity must continue. In this work it is important to be aware of limitations in naturalistic studies such as the risk of interchanging cause and effect and the necessity to carry out control for confounders. Meta-analysis is a strong tool for summing up results of previous research. Meta-analyses can be used in reporting the evidence for effectiveness of interventions, but also for determining risk or identifying risk factors. A meta-analysis of risk factors of repetition of suicide attempt has not been carried out, and the quality of the identified studies did not allow a formal meta-analysis. Large randomised clinical trials examining the effectiveness of interventions on reducing rate of suicide attempt and suicide should have high priority. Suicide is a major public health problem and should be given high priority with regard to prevention and research. (ABSTRACT TRUNCATED)

A meta-analysis of risk factors of repetition of suicide attempt has not been carried out, and the quality of the identified studies did not allow a formal meta-analysis. Large randomised clinical trials examining the effectiveness of interventions on reducing rate of suicide attempt and suicide should have high priority. Suicide is a major public health problem and should be given high priority with regard to prevention and research. (ABSTRACT TRUNCATED)     

Self-injurious behavior and attempted suicide in purging bulimia nervosa: associations with psychiatric comorbidity

BACKGROUND: Few studies, to date, have investigated the relationship between self-damaging behavior and the presence of comorbid psychiatric diagnoses in eating disorders. The aim of the present study was to investigate the axis I and II comorbidity in subjects with bulimia nervosa who report self-injurious behavior and/or suicide attempt. METHODS: The subjects were 95 patients with purging type bulimia nervosa who underwent a clinical evaluation assessing the presence of self-injurious behavior and suicide attempts, comorbidity for axis I and II psychiatric disorders and temperament. RESULTS: No axis I diagnosis was associated with any type of self-injurious behavior, whereas social phobia and bipolar disorder were linked to attempted suicide. Significant independent predictors of impulsive self-injurious behavior were the presence of childhood sexual abuse, high harm avoidance scores, and high self-transcendence scores, whereas childhood sexual abuse, the presence of a cluster B personality disorder, and a low self-directedness were predictors of suicide attempts. Compulsive self-injurious behavior was significantly associated with harm avoidance and cluster C personality disorders. Harm avoidance was also associated with skin picking. CONCLUSIONS: Personality disorders are a frequent correlate of the presence of SIB in purging bulimia nervosa. However, temperament seems to play a more important role. Further studies on larger samples are necessary to confirm our findings in bulimia nervosa and to extend them to other patient populations.     

Suicides and serious suicide attempts: two populations or one?

BACKGROUND: Few studies have examined the extent to which populations of suicides and attempted suicides are similar, or different. This paper compares suicides and serious suicide attempts in terms of known risk factors for suicidal behaviour. METHODS: Using case-control methodology, risk factors for suicidal behaviour were examined in 202 individuals who died by suicide, 275 individuals who made medically serious suicide attempts and 984 randomly selected control subjects. Based on data from significant others, measures used spanned sociodemographic factors, childhood experiences, psychiatric morbidity and psychiatric history, exposure to recent stressful life events and social interaction. RESULTS: Multiple logistic regression identified the following risk factors that were common to suicide and serious suicide attempts: current mood disorder; previous suicide attempts; prior outpatient psychiatric treatment; admission to psychiatric hospital within the previous year; low income; a lack of formal educational qualifications; exposure to recent stressful interpersonal, legal and work-related life events. Suicides and suicide attempts were distinguished in the following ways: suicides were more likely to be male (OR = 1.9, 95% CI 1.1, 3.2); older (OR = 1.03, 95% CI 1.02, 1.04); and to have a current diagnosis of non-affective psychosis (OR = 8.5, 95% CI 2.0, 35.9). Suicide attempts were more likely than suicides to have a current diagnosis of anxiety disorder (OR = 3.5, 95% CI 1.6, 7.8) and to be socially isolated (OR = 2.0, 95% CI 1.2, 3.5). These findings were confirmed by discriminant function analysis, which identified two functions that described the three subject groups: the first function discriminated the two suicide groups from control subjects on a dimension corresponding to risk factors for suicide; the second function discriminated suicide from suicide attempt subjects on a series of factors including gender, non-affective psychosis and anxiety disorder. CONCLUSIONS: Suicides and medically serious suicide attempts are two overlapping populations that share common psychiatric diagnostic and history features, but are distinguished by gender and patterning of psychiatric disorder.     

A database review in C-L psychiatry: characteristics of hospitalized suicide attempters

A computerized database was used to study the characteristics of psychiatric consultations in patients admitted to nonpsychiatric services. The authors reviewed a consultation practice with suicide attempters over a four-year period and compared the patients with a patient sample matched for gender and age also seen by the service. For suicide attempters, the time elapsed between admission to the service and the consultation, as well as the lengths of stay, were significantly shorter. Suicide attempters were significantly more likely to have mood disorders and Axis II disorders. The authors review the role of consultation psychiatrists with these patients and suggest that a triage model fits the services provided and the needs of nonpsychiatric physicians.     

Suicide attempts: differences between unipolar and bipolar patients and among groups with different lethality risk

BACKGROUND: The present naturalistic study aimed to distinguish between suicide attempts (SAs) of bipolar and unipolar patients, and among SAs characterized by different lethality risk. METHODS: The records of 2395 consecutive admissions to our psychiatric intensive care unit (PICU) were assessed for presence of suicide attempt (SA). Cases of SA were rated for symptom severity with the brief psychiatric rating scale (BPRS), the scale for the assessment of positive symptoms (SAPS), the scale for the assessment of negative symptoms (SANS), the mini mental state examination (MMSE), the global assessment of functioning scale (GAF) and the clinical global impression (CGI). An original questionnaire was administered to explore clinical aspects related with suicidal behavior. RESULTS: Among 2395 admissions, 80 (3.3%) had attempted suicide. Fifty-three cases (66.2%) suffered from a mood episode, including 22 (27.5%) with unipolar depression and 31 (38.7%) with bipolar depression (types I and II combined) or mixed state, while 27 (33.8%) cases received other diagnoses. Forty-eight (60%) cases had attempted suicide prior to the index episode. Ten cases (12.5%) had a relative who attempted or committed suicide. Thirty-nine cases (48.7%) described their SA as impulsive. Twenty cases (25.0%) reported alcohol ingestion before SA. In comparison with women, men used more violent methods. Cases characterized by a non-lethal risk SA had higher BPRS psychotic cluster and SAPS scores than cases with either low or high lethal risk SA. Bipolar cases were over-represented in the high lethality risk group. BPRS anxiety-depressive cluster score was higher in unipolar than in bipolar cases. LIMITATIONS: The sample may not be representative of all patients with SA. The questionnaire has not been standardized for use in psychiatric populations. CONCLUSIONS: The higher proportion of high lethal risk SA in bipolar cases suggests that the risk of completed suicide is higher in bipolar disorder than in unipolar depression. The risk of lethality in SA was not associated with the intensity of symptoms of anxiety and depression.
