Psychiatric Aftercare and Suicide Risk: A Case-control Study Using Blind Rating

Blindly abstracted records of last episode of care together with aftercare records of 39 psychiatric patient suicides and their matched controls were rated blind for suicidal talk during aftercare, reduction of aftercare at last appointment and high-low suicide risk. Neither suicidal talk nor reduction of aftercare was confirmed as a predictor of suicide, although trends in the predicted directions were observed. Blind estimates of high-low risk correctly identified a significant minority (40%) of suicides but at the cost of misclassifying 60% as controls. Evidence is still lacking that clinicians blind to case identity may, from records, reliably distinguish a majority of suicides from their matched controls. Some implications for practice and research are discussed.

CSF 5-HIAA, suicide intent and hopelessness in the prediction of early suicide in male high-risk suicide attempters

OBJECTIVE: To study the predictive value of the Beck Suicide Intent Scale (SIS), the Beck Hopelessness Scale (BHS) and of 5-hydroxyindoleacetic acid (5-HIAA) in the cerebrospinal fluid for future early suicide in a group of high-risk male suicide attempters. METHOD: Fifteen consecutive male suicide attempters admitted to a psychiatric ward at the Karolinska Hospital, who were not receiving any treatment with antidepressants were diagnosed according to DSM-III, assessed with SIS and BHS and submitted to lumbar puncture. All patients were followed up for cause of death. RESULTS: Five early suicides (within 2 years) were identified. Mean cerebrospinal fluid (CSF) 5-HIAA differed between suicides and survivors. Low CSF 5-HIAA was identified in those who committed early suicide. Neither the Suicide Intent Score nor the Hopelessness Score distinguished suicides from survivors. CONCLUSION: In high suicide risk hospitalized male psychiatric patients CSF 5-HIAA may be a better predictor of early suicide after attempted suicide than SIS or BHS.     

Suicidality in bipolar compared to unipolar depressed inpatients

The aim of the present analyses was to evaluate differences in suicidality (past suicide attempts, suicidal thoughts at time of admission and completed suicides during the hospital stay) between bipolar and unipolar depressed inpatients. Apart from a higher frequency of past suicide attempts in bipolar depressed patients (26.6% in bipolar vs. 17.8% in unipolar patients), findings do not indicate any further differences in suicidality (suicidal thoughts (about 40% in both groups) and completed suicides during the hospital stay (0.8% in both groups)) between bipolar and unipolar patients. Factors with a predictive value for suicidal thoughts at the time of admission were a positive family history for affective disorders, past suicide attempts, and the depressive and paranoid hallucinatory syndrome (all associated with an increased risk). Female gender, an older age at hospitalisation and a longer duration of the illness were found to be associated with a lower probability for having suicidal tendencies at the time of admission. The risk for committing suicide during the hospital stay was increased if the patients had a history of past suicide attempts and suicidal thoughts at the time of admission. A more pronounced depressive syndrome at time of admission was slightly associated with a lower risk of committing suicide. Received: 25 April 2000 / Accepted: 28 June 2000     

Where schizophrenic patients commit suicide: a review of suicide among inpatients and former inpatients

OBJECTIVE: To review the literature on suicide of inpatients with schizophrenia, to identify suicide risk factors as well as typical patterns of behavior and to suggest a rationale and strategies for future interventions. METHOD: A computerized MedLine, Excerpta Medica and PsycLit search supplemented by an examination of cross-references and reviews. RESULTS: Up to half the suicides among patients with schizophrenia occur during inpatient admission. Inpatient suicides were found among those of a young age group who were predominantly single, childless and socially isolated. The vast majority experienced an illness characterized by long duration and prolonged psychiatric hospitalizations or multiple admissions and discharges. Up to 50% of the suicides occurred in the first few weeks and months following discharge from the hospital. The paranoid subtype of schizophrenia, where positive symptoms prevail and negative symptoms are few, is associated with a suicide risk that is three times greater than that associated with nonparanoid subtypes and eight times greater than the risk associated with the deficit subtype. CONCLUSIONS: Treatment of suicide is a major problem among inpatients with schizophrenia. Evidence suggests that suicide is generally carried-out by patients who have been recently discharged or by those who manage to get away from the hospital. Strategies aimed at preventing this phenomenon have been introduced to the medical personnel, but suicide in these patients does not seem to have been reduced. We emphasize the need to establish guidelines for the prevention of suicide in hospitalized patients with schizophrenia.     

Et par praktiske bidrag til behandlingen af kroniske psykotiske patienter: Bevægelsesterapi og adfærdstræning

Our aim was to investigate whether a large number of hospital visits by children and adolescents because of injuries are associated with psychiatric treatments and subsequent suicides. We examined the case records of 250 randomly chosen patients, 156 (62%) boys and 94 (38%) girls, out of 2306 outpatients who were 0-16 years old and had been treated because of traumatic injuries in Oulu University Hospital in 1984 and were alive in 1997. Boys with seven or more accidents had had psychiatric treatments more commonly than did boys with fewer accidents (39% vs. 8%). In addition, the case records of the patients who had died before the end of 1997 out of the 2306 patients were examined. Twenty-one (0.9%) patients (20 males and one female) had died, and seven (0.3%) of them had committed suicide. The traumatically injured male patients had a twofold suicide rate compared to the national average. The researchers also re-coded the causes of death from the death certificates. There seems to be a tendency to interpret adolescent suicides as accidental, as one of the seven registered suicides (14%), but six of the seven re-coded suicides (86%) had occurred before the age of 20.     

Traumatic injuries of children and adolescents--are they associated with psychiatric contacts?

Our aim was to investigate whether a large number of hospital visits by children and adolescents because of injuries are associated with psychiatric treatments and subsequent suicides.

Attempted suicide in Denmark. IV. A five-year follow-up

From October 1, 1980 to April 20, 1981, 207 patients were admitted to the Department of Psychiatry, Odense University Hospital, after attempting suicide. Information on physical, mental and social conditions was collected. The patients were then followed for 5 years, to register subsequent suicidal behaviour and to try to identify relevant factors for evaluation of future suicide risk. During the follow-up period 11.6% of the attempters committed suicide, the majority within the first year after the index attempt. Seventy-five percent of the suicides were committed less than 6 months after the last contact with the psychiatric ward. Predictors for future suicide were chronic somatic disease, depression, abuse of medicine, and chronic alcohol abuse. The authors emphasize the need for a thorough medical evaluation of patients attempting suicide, to be able to identify and eventually treat these conditions.     

General hospital suicides--a psychological autopsy study in Finland

Although both severe medical disorders and mental disorders are established risk factors for suicide, it is not known if patients who commit suicide in general hospitals differ from others. This study investigated current mental disorders and other clinical characteristics among general hospital suicide victims and compared them with other suicide victims in an unselected nationwide population. Drawing on data from a psychological autopsy study of all suicides (N = 1397) in Finland during one year, all suicides committed by patients in a general hospital setting were identified. Retrospective DSM-III-R consensus diagnoses were assigned and general hospital suicide victims were compared with other suicide completers in terms of clinical characteristics. Twenty-six general hospital suicide victims, 1.9% of all suicides, were identified. Subjects who completed suicide during general hospital treatment were older and used more violent suicide methods than other suicide victims. One or more diagnoses of psychiatric (Axis I) disorders were assigned for 88% of the general hospital suicide victims. Overall, the most prevalent disorder was major depression, which was more common among the general hospital suicide victims, even when age was controlled for. The findings of this study suggest that most people who commit suicide during a spell of general hospital treatment suffer from current mental disorder, as do suicide victims in general. The recognition and treatment of major depression in particular should be improved in order to prevent suicide in general hospitals.     

The Clarke Institute experience with completed suicide: 1966 to 1997.

OBJECTIVES: To describe the caseload of completed suicides at a single psychiatric facility and to review the perceived deficiencies in the care of those patients. METHOD: Demographic and diagnostic data, clinical circumstances, and the deficiencies in care and documentation or both were extracted from medical records and post-suicide audit reports. RESULTS: There were 276 completed suicides over the period reviewed, yielding suicide rates of 206 per 100,000 registered patients and 123.5 per 100,000 inpatient discharges. The male to female ratio was 2:1, and patients with schizophrenia or depression accounted for 63.7% of the caseload. Only 18% of inpatients were involuntary, and only 10% were under individual observation at the time of suicide. Individual psychiatrists had up to 15 suicides in their caseloads. Deficiencies and recommendations pursuant to case audits are summarized. CONCLUSION: This is the first report of the entire cumulative experience with completed suicide, including audited deficiencies in the care and documentation of that caseload, at a single Canadian psychiatric facility.     

Suicide in Hong Kong

Coroners' statistics indicated there were 684 suicides for the whole of Hong Kong in 1981. This gave a crude suicide rate of 18.1 per 100,000 population aged 15 years and over and constituted 2.7% of all deaths reported in that year. Only a few data were recorded in all coroners' files but additional data were obtained from police records on 168 of these suicides. The age and sex distribution among the suicides as well as the effect of marital and employment status on suicide rates were found to be similar to western countries. Jumping from a height was the most common method of suicide (47.2%) followed by hanging (30.8%). Psychiatric illness and chronic physical disability were two most important precipitating causes of suicide (39.8% and 35.7% respectively). Twenty per cent had a history of previous attempts with one-third occurring within six months of their completed suicide. Over 40% had communicated their suicide intention to others, while 19% left a note. 'Psychiatric' cases as a group had special features: there were more in the younger age groups, more with records of previous suicide attempts and more chose readily available methods.     

Predicting inpatient suicides and suicide attempts by using clinical routine data?

OBJECTIVE: The study aimed at exploring prevalence and risk factors of inpatient suicides and attempted suicides in a psychiatric hospital. METHOD: Based on the German psychiatric basic documentation system, 20,543 patients with 40,451 episodes of inpatient care (1995-2004) in a psychiatric state hospital were included. Besides univariate analyses, multivariate logistic regression analyses and classification and regression tree analyses were performed. RESULTS: Forty-one inpatient suicides were recorded. Risk of inpatient suicide is increased for patients with resistance to psychopharmacological treatment, previous suicide attempt, severe side effects and supportive psychotherapy before admission. Two hundred fourteen inpatient suicide attempts occurred during the 10-year period. Risk factors of inpatient suicide attempt are assault, personality disorder, previous suicide attempt, psychopharmacological treatment resistance, suicidal thoughts at admission, schizophrenia, depression, female sex and length of stay. CONCLUSION: The identified risk factors underline the need for a cautious investigation of previous suicide attempts as well as for giving special attention to patients who have problems with psychopharmacotherapy during hospitalization.     

Child and adolescent suicides in Virginia: 1987 to 2003

OBJECTIVES: The aim of this study was to better understand suicides in children and adolescents using records from the Office of the Medical Examiner of Virginia from 1987 to 2003. MAIN FINDINGS, KEY DATA, AND STATISTICS: Suicide accounted for 16.8% of unnatural deaths. Suicide rates were highest for Caucasians. Guns were the most common method of death for suicides, followed by hanging and poisoning. Poisoning other than carbon monoxide accounted for 7.8% of suicides, with tricyclic antidepressants (TCAs) the most identifiable poison. Female youths were 10 times more likely to die from TCAs than male youths, after adjusting for race and age. CONCLUSIONS: Guns and hanging were the principal methods of suicide. Among the antidepressants, TCAs have been the most common poisons used in suicide. Increasing age was a powerful determinant of suicide. Some patients may have stockpiled their TCAs for a while before their TCA overdose. Other suicide victims may have used TCA supplies from family members. Hence, some of the suicide victims may not have taken TCAs on a regular basis before committing suicide. Further exploration of TCA-induced suicidal thoughts is needed. Conclusions cannot be made at the time about the precise role that TCAs played in TCA-induced suicide reported in our study.     

Predictors of suicide in psychiatric hospital

OBJECTIVE: About 5% of all suicides occur in psychiatric hospitals. The aim of this study was to look for potential characteristics common to patients who committed suicide in psychiatric hospital. METHOD: All patients who committed suicide in University Psychiatric Hospital in Ljubljana, Slovenia, in the period 1984-1993 were included. The suicidal patients (SP) with schizophrenia (SCH) and affective psychoses (AP) were compared to an age-, sex- and diagnosis-matched control group. Data from files and (in control patients) patient interviews were gathered. Multivariate logistic regression analysis was used. RESULTS: A total of 79 patients (34 males and 45 females) committed suicide. The majority of them had SCH (n = 36) and AP (n = 23). The predictors of suicide among patients with AP and SCH were depression and lack of insight and, in addition in patients with SCH, past suicidal behaviour and poor relationships with family members. CONCLUSION: This study provides the clinician with information on risk factors for in-patient suicide.     

Cerebrospinal fluid monoamine metabolites and suicide

Prospective studies of the serotonergic system and suicide report that low 5-hydroxyindolacetic acid (5-HIAA) in the cerebrospinal fluid (CSF) and a history of attempted suicide predict suicide risk. Low CSF homovanillic acid (HVA) is reported to be associated with past and future lethality of suicide attempts but not with suicide. The interrelationships between monoamine metabolites, violent method, suicide intent and lethality of suicidal behaviour are complex. We hypothesized that CSF 5-HIAA and HVA levels are related to suicide intent, violence and lethality of suicidal behaviour. Fifteen male suicide attempters admitted to a psychiatric ward at the Karolinska University Hospital and eight healthy male volunteers were submitted to lumbar puncture and CSF 5-HIAA and HVA were assayed. Suicide intent with the Beck Suicide Intent Scale (SIS), lethality and violence of suicidal behaviour were assessed. All patients were followed up for causes of death. Six suicides and one fatal accident were identified with death certificates. Mean CSF 5-HIAA but not CSF HVA differed between suicides and survivors. Violent suicides had higher suicide intent and CSF 5-HIAA than non-violent suicides. In violent suicides, CSF 5-HIAA levels were negatively correlated with SIS. Greater suicide intent may be associated with greater aggressive intent and predicts a violent suicide method.     

An assessment of suicide in an urban VA Medical Center

This study characterizes those patients of an urban VA Medical Center (VAMC) who had committed suicide. A cause-of-death search of the 1,075 veterans from the VAMC's case rolls who died during 1998 was conducted. For confirmed and suspected suicides, a chart review was conducted, noting psychiatric history and recent contact with the VAMC. Nineteen patients were either confirmed or suspected suicides. Few of these patients had made recent contact with the VAMC, although the majority of them had received psychiatric services from the VA at some time. The proportion of deaths due to suicide was similar in African American and White patients. Rates of suicide were elevated, primarily because of the high proportion of patients receiving psychiatric treatment. Elderly suicides were less likely to have had psychiatric services or previous psychiatric diagnoses than were younger suicides. Patients with past contact with psychiatric services may be especially at risk of suicide, particularly as contact with these services diminishes. Elderly patients in medical settings with undiagnosed or undertreated psychiatric disorders are also likely to have elevated risk for suicide. These findings demonstrate the importance of acknowledging that risk factors for suicide are specific to sites or populations; this information can be used in allocating resources for developing site-specific strategies for prevention.     

Completed suicide among psychiatric in‐patients with depression in an Australian mental hospital

Up to 45% of completed psychiatric in‐patient suicides have a diagnosis of depression. Twenty‐two completed psychiatric in‐patient suicides with depression, over a 21‐year period, in a large psychiatric hospital in Melbourne, Australia, were examined. The characteristics, including demographic and clinical data, for the completed suicides with depression were compared with a comparison group of ‘alive’ in‐patients with depression. Completed suicide among psychiatric in‐patients with depression was associated with male sex, suicidal thoughts during admission, and fluctuating suicidal ideation or continuous absence of suicidal ideation. Over 40% of completed suicides occurred whilst on approved leave and over 20% after absconding from the hospital. Violent methods (including jumping in front of trains, trams and road traffic, jumping of buildings, hanging and drowning) were used in over 65% of completed suicides. Psychiatric units should be developed away from readily available methods of suicide. In‐patients with suicidal thoughts during the admission and unstable suicidal ideation should be carefully observed to avoid absconding and suicide, and should be carefully assessed prior to granting of leave.

Suicides in close connection with psychiatric care: an analysis of 57 cases in a Swedish county

Among 523 suicides committed in 1977-1984, 10 took place in a psychiatric hospital ward, 17 after the patient had left the ward without permission, 21 while the patient was on leave and nine 0-7 days after discharge. These 57 subjects were compared with 271 suicides committed more than 7 days after discharge or during outpatient care only (PCO). The male:female ratio was 1.0 in the former (PCI) group and 2.0 in the PCO group. The median age of the PCI subjects was 38 years. The suicide method was hanging in all 10 suicides (2 males, 8 females) committed in the psychiatric hospital ward. Depressive syndromes and, particularly schizophrenic and paranoid psychoses were more frequent among the PCI than among the PCO subjects. The extent of psychiatric care, as assessed by the number of admissions, was much greater in the PCI than in the PCO subjects. Environmental factors that might have been of causative importance for the suicidal act were of various kinds and differed to some extent between the two groups. Among the PCI subjects women seemed to have experienced family troubles more often than men, and situations of stressful psychiatric rehabilitation were more common among men.
