The prevalence of aborted suicide attempts among psychiatric in-patients

We report the prevalence of aborted suicide attempts in which the essential characteristics are (i) intent to kill oneself, (ii) a change of mind before making an actual suicide attempt and (iii) the absence of physical injury. The lifetime history of aborted suicide attempts was assessed by semi-structured interview of 733 patients, aged 18–59 years, who were consecutively admitted to a psychiatric hospital. In the study group, 46% of subjects had made a suicide attempt and 29% had made at least one aborted attempt during their lifetime. Subjects who had made aborted attempts were more likely to have made actual attempts. Approximately 11% of the subjects in the study group had a history of aborted attempts of potential high lethality, such as going to a height in order to jump, or holding a gun to the head. There were no major demographic differences between those with and without a history of aborted attempts. However, among those with no prior history of actual attempts, subjects with depression and a family history of suicide were more than twice as likely as those without such a history to have made an aborted attempt. Aborted suicide attempts are a common suicidal behaviour among psychiatric in-patients. Whether they predict actual attempts or suicide warrants prospective investigation.     

Risk factors for suicide among patients with schizophrenia

In order to assess risk factors for suicide among patients with schizophrenia, we compared 32 patients with schizophrenia who committed suicide during an 11 year follow-up with a control group of 64 schizophrenics who did not commit suicide. A history of previous suicide attempts was the factor most strongly related to suicide. In females we found an increased risk for suicide among unmarried, divorced or widowed and among those living alone. In males we found an increased risk among those with a history of alcohol abuse. In contrast to findings in other studies, distribution of age and sex and a history of depressive episodes were factors not associated with an increased risk for suicide. We conclude that suicidal acts among schizophrenics are often impulsive and difficult to predict. Traditional risk scales are of limited value in the clinical assessment of suicidal risk.     

Depressed Suicide Attempters with Posttraumatic Stress Disorder

Posttraumatic stress disorder and major depressive disorder are well-established risk factors for suicidal behavior. This study compared depressed suicide attempters with and without comorbid posttraumatic stress disorder with respect to additional diagnoses, global functioning, depressive symptoms, substance abuse, history of traumatic exposure, and suicidal behavior. Adult patients consecutively admitted to a general hospital after a suicide attempt were interviewed and assessed for DSM-IV diagnosis and clinical correlates. Sixty-four patients (71%) were diagnosed with depression; of them, 21 patients (32%) had posttraumatic stress disorder. There were no group differences in social adjustment, depressive symptoms, or suicidal intent. However, the group with comorbid depression and posttraumatic stress disorder had more additional Axis I diagnoses, a higher degree of childhood trauma exposure, and more often reported previous suicide attempts, non-suicidal self-harm, and vengeful suicidal motives. These findings underline the clinical importance of diagnosis and treatment of posttraumatic stress disorder in suicide attempters.     

Suicidal behaviour in early psychosis

OBJECTIVE: This was to determine the prevalence of suicidal behaviours prior to and during the first year of treatment in a comprehensive early psychosis program (EPP) and to identify predictors of suicidal behaviour. METHOD: In a cohort study of 238 subjects, patients were assessed at initial presentation to an EPP and 1 year later. Measures included a range of demographic variables, suicide attempts, depression, positive and negative symptoms, social functioning and substance misuse. RESULTS: Although 15.1% attempted suicide prior to program entry, only 2.9% made an attempt in the year after program entry and 0.4% completed suicide. No further attempts were seen in those with previous parasuicide. These rates are lower than other published rates for first-episode patients. CONCLUSION: It is possible that specifically designed first-episode programs can reduce the suicidal behaviour in this high-risk population. The low prevalence of attempted suicide makes modeling predictors difficult.     

Antecedents and Patterns of Suicide Behavior in First-Admission Psychosis

Background: Persons with psychotic illnesses have an increased risk for suicide, especially early in the illness. Sufficient knowledge allowing for early recognition is lacking. Objectives: To describe suicide behaviors before and during the 4 years following first psychiatric hospitalization, examine associations of demographic and psychiatric risk factors, and develop a suicide risk index. Method: Data came from the Suffolk County Mental Health Project, a first-admission cohort (n = 529). Cox regression was used to study associations of risk factors to suicide behaviors; a summary suicide behavior risk index was also tested. Results: Prior to first admission, 28.0% (n = 148) of the cohort had attempted suicide. During the 4-year follow-up, 13.6% (n = 72) of the cohort attempted suicide (29.7% of those with previous attempts and 7.3% making their first attempt) and 3 respondents died of suicide. The significant predictors at index admission of subsequent attempts were prior attempts or ideation, severity of depressive symptoms and thought disorder, lifetime substance abuse, and younger age. Suicide ideation was predicted by the same variables with the addition of insight into illness and with the exception of age at admission. A 3-category risk index was created; 61.1% of those who made a suicide attempt were in the highest risk group (n = 44/72). Conclusion: The current study confirms and extends previous research showing that risk factors early in the course of illness are predictive of subsequent ideation and attempts. The risk index may be a useful adjunct in identifying individuals likely to benefit from preventive interventions.     

Evaluation of psychiatric consultations with suicide attempters

Diagnosis, management and disposition were evaluated in 120 psychiatric consultations with patients referred to a university hospital following an attempted suicide. Data were registered by hospital nurses and psychiatric consultants, and the patients were extensively interviewed after discharge. Many patients (43%) had been admitted to a psychiatric hospital on previous occasions or at the time of the suicide attempt. In almost one third of the cases, the consultants did not take sufficient interest in the patients' accounts of the last and previous suicide attempts. Their estimation of the reoccurrence of suicidal behaviour had a low predictive value (54%). One fourth to one half of the patients were negative about or not satisfied with the consultation. The compliance with the psychiatric consultants' referrals, however, was very high (79%). Although a large group of patients received effective care, the consultants did not pay enough attention to the group of (former) in-patients with recurrent suicidal behaviour. Possible causes and consequences of these findings are discussed.     

Deliberate self-poisoning: treatment follow-up of repeaters and nonrepeaters.

Since 1986 psychiatrists and social workers of the Lund Suicide Research Center have investigated subjects admitted to the medical intensive care unit after a suicide attempt. Fifty-nine of 79 deliberate self-poisoners were interviewed 12 months after a suicide attempt. Twenty-one had previously been interviewed 6 months after the index suicide attempt. We obtained minor information on 8 subjects. Two patients had committed suicide. Sixteen subjects (27%) of those who were interviewed showed repeated suicidal behavior (repeaters) during the 1-year follow-up, and their psychiatric diagnoses at the index attempt were most commonly alcohol abuse and dysthymia (DSM-III, Axis I). Compared with nonrepeaters, repeaters had more often made previous suicide attempts, their index attempt was less serious and they were more often in psychiatric treatment at index. At follow-up, repeaters more often than nonrepeaters expressed the need for professional mental health support. Two-thirds of the patients were in treatment at follow-up. About half had remained in continuous treatment and most in psychiatric care for more than 1 year. Repeated self-poisoning occurred despite ongoing treatment. In view of the fact that numerous suicide attempters obviously remain in treatment for several years, we suggest further development and evaluation of long-term treatment strategies.     

Selection of patients who attempted suicide for psychiatric consultation.

A total of 1018 self-poisoned patients were treated during one year (1983) at the emergency room of Helsinki University Central Hospital for 1207 suicide attempts; 46% were left without psychiatric consultation. Women were consulted more frequently than men. Patients with previous psychiatric treatment were referred more often for psychiatric consultation. The use of alcohol was more frequently present in suicide attempts that did not lead to psychiatric consultation. Somatic seriousness was also less severe in this group. It was assumed that those left without consultation were not in mortal danger. There were no differences in the suicide mortality of these 2 groups during a 5-year follow-up.     

Suicide attempts in which alcohol is involved: a special group in general hospital emergency rooms

Sixty-two percent of 1018 parasuicide patients treated in the emergency room of Helsinki University Central Hospital in 1983 for 1207 suicide attempts had recently consumed alcohol in addition to medical drugs: 46% were women and 54% men. High body alcohol levels were associated with young age and male gender. Alcohol consumption shortly before, or at the time of, parasuicidal acts was more common among young or lonely men with previous suicide attempts. Their suicide risk was assessed as less severe and they were less often referred to a psychiatrist compared with those who had not consumed alcohol. They were also more often left without arranged after-care. By the end of a 5.5-year follow-up period, 3.3% of these alcohol consumers had committed suicide, an annual suicide mortality of 598/100,000. In the year following the initial attempt, suicide mortality was 1809/100,000, a 51-fold risk compared to that of the total population in Helsinki. Sixty-seven percent of alcohol consumers during the initial suicide attempt also took it before actually committing suicide, and 30% of these revealed clear evidence of chronic alcohol consumption. Those who initially consumed alcohol were identifiable as a risk group for suicide, and thus improvement in their recognition and treatment in the emergency rooms of general hospitals is recommended.     

Suicidal behaviour of psychiatric in-patients

OBJECTIVE: The study aimed to examine suicidal behaviour before and during in-patient care in a psychiatric state hospital. METHOD: Based upon a psychiatric basic documentation system prevalence and risk factors of in-patient suicides, suicide attempts and suicidal thoughts were investigated over an 11-year period from 1989 until 1999. RESULTS: A total of 30 in-patient suicides were found among 21 062 patients. According to the multivariate logistic regression analysis the risk of hospital suicide increases for patients with schizophrenia, higher cumulative length of stay, previous suicide attempt, part-time employment and training/retraining. Predictors of suicide attempt during hospitalization are suicide attempt on admission, personality disorder, suicidal thoughts on admission, schizophrenia and affective disorder. CONCLUSION: As Schizophrenics represent the high-risk group of in-patient suicide, suicide prevention should be a major goal in their treatment. More frequent suicide risk assessment is recommended particularly before granting a leave or an outing.     

Suicide attempts by battered wives.

During an 8-month period a total of 117 battered wives, all seeking emergency surgical care, were identified. Twenty-two of the battered wives were found to have made 82 suicide attempts during the 16-year study period. This corresponds to an incidence more than 8 times that of an unselected population of women being treated because of attempted suicide in the same hospital. The suicide attempts were predominately passive methods. Although conflict with the husband was the most common triggering factor for the attempt, mental disorder of the woman was another main cause. It is concluded that the doctor, when confronted with a patient who has attempted suicide, always should consider the possibility of ongoing physical abuse. Although battering generally is not the only explanation, the physician should remember this possibility and the patient should, if necessary, be referred to proper care services.     

The Additive Effect on Suicidality of Family History of Suicidal Behavior and Early Traumatic Experiences

Family history of suicidal behavior and personal history of childhood abuse are reported risk factors for suicide attempts and suicide completion. We aim to quantify the additive effect of family history of suicidal behavior and different subtypes of childhood abuse on suicidal behavior. We examined a sample of 496 suicide attempters, comparing individuals with family history of suicidal behavior and personal history of childhood (physical or sexual) abuse, individuals with family history of suicidal behavior only, individuals with history of early traumatic experiences only, and individuals with none of these two risk factors with regards to suicidal features. An additive effect was found for the age at the first attempt in suicide attempters with both family history of suicidal behavior and either physical or sexual abuse. No significant interactions were found between family history of suicidal behavior and childhood trauma in relation to any characteristics of suicidal behavior. Subjects presenting family history of suicidal behavior and childhood abuse attempt suicide earlier in life than subjects with just one or none of them, particularly if they were sexually abused. Other suicidality indexes were only partially or not associated with this combination of risk factors. A careful assessment of patients with both family history of suicidal behavior and childhood abuse could help to prevent future suicide attempts, particularly in young people.     

Assessing varying degrees of lethality in depressed adolescent suicide attempters.

OBJECTIVE: Understanding the lethality of suicide attempts and its relation to other psychological variables may improve clinical judgement with regard to suicide risk. METHOD: The lethality of suicidal behaviour was examined in 60 hospitalized adolescent in-patients who had recently attempted suicide. Subjects were divided into non-lethal, low-lethal and high-lethal groups based on the qualities of their suicidal acts. RESULTS: The groups did not differ in terms of hopelessness, depression, substance abuse or self-esteem. Moreover, they did not differ significantly in diagnoses of major depression, adjustment disorder, substance abuse and bipolar disorder. The group of high-lethal attempters was the only group with several individuals diagnosed with a major depressive episode and comorbid attention deficit disorder. The high-lethal group also reported the strongest desire to end their lives. CONCLUSION: Based on lethality of suicide attempts, adolescent suicide attempters can be differentiated in terms of the wish to die as well as some instances of diagnostic comorbidity. However, they may not be differentiated in terms of severity of depression or hopelessness, demographic variables and other aspects of suicidal behaviour.     

Suicide attempts among Inuit youth: a community survey of prevalence and risk factors

The prevalence of and risk factors for attempted suicide and suicidal ideation were examined with a survey of 99 Inuit, aged 14–25 years, residing in a community in Northern Québec. A total of 34% of survey respondents reported a previous suicide attempt, and 20% had attempted suicide more than once. A suicide attempt had resulted in injury in about 11 % of those surveyed. The prevalence of suicidal ideation was also very high: 43% of subjects reported past thoughts of suicide, and 26% had had suicidal thoughts during the month before the survey. Risk factors for suicide attempts included male gender, having a friend who had attempted or committed suicide, a history of being physically abused, a history of solvent abuse, and having a parent with an alcohol or drug problem. Protective factors included a family history of having received treatment for a psychiatric problem, more frequent church attendance, and a high level of academic achievement. While individuals in the community who are at high risk for suicide can be targeted for preventive measures, the high prevalence and effect of family problems on likelihood of suicide attempts indicate the need for family- and community-based approaches.     

Decreased serum albumin levels in Taiwanese patients with schizophrenia

Previous papers have reported lower serum albumin levels in patients with schizophrenia. In the present study, the relationships between serum albumin levels and subtypes of schizophrenia, physical violence and suicide attempts were investigated. A review of medical charts over a 1-year period was carried out in a population of 213 Taiwanese psychiatric inpatients that included 106 patients with schizophrenia. The collected data included age, bodyweight, height, serum albumin levels and routine blood biochemistry examinations. These data were compared with data from a healthy control group (n = 32) composed of staff members using analysis of covariance after age adjustment. The statistical results showed significantly lower serum albumin levels in patients with schizophrenia in the acute phase than in the control group. However, no significant differences in serum albumin levels were found between paranoid and non-paranoid schizophrenic patients, between patients who had or had not exhibited physical violence, or between patients who had or had not made a suicide attempt.     

The Relationship of Self-reported Executive Functioning to Suicide Ideation and Attempts: Findings from a Large U.S.-based Online Sample

An increasing number of studies demonstrate that individuals with a history of suicidality exhibit impaired executive functioning abilities. The current study examines whether these differences are linked to suicidal thoughts or suicidal acts—a crucial distinction given that most people who think about suicide will not act on their thoughts. A large online sample of U.S. participants with a history of suicide ideation (n = 197), suicide attempts (n = 166), and no suicidality (n = 180) completed self-report measures assessing executive functioning, suicide ideation and attempts; in addition, depression, self-efficacy, and history of drug abuse and brain injury were assessed as potential covariates. Individuals with recent suicide attempts reported significantly worse executive functioning than ideators. This difference was not accounted for by depression, self-efficacy, history of drug abuse or brain injury. Self-reported executive functioning may represent an important short-term risk factor for suicide attempts.     

Characteristics of Recent Suicide Attempts by Inmates in Maximum Security Correctional Centers

The research examined inmates' subjective perceptions of the reasons for suicide attempts and the psychological, sociological and criminological factors associated with such attempts. The sample comprised 60 male inmates who had made a recent suicide attempt. The methods of examination were semi-structured interviews with the inmates and analysis of their psychological and criminological files. The results showed that the examined group was not totally homogeneous. Methods of suicidal attempts divided the sample into two groups: those who had made a non-life-threatening (NLT) suicide attempt (58%) and those who made a life-threatening (LT) attempt (42%). Several factors significantly differentiated NLT and LT groups. Four of these factors were combined in regression models to clarify the relationships between the variables and to predict, in retrospect, whether an inmate had made a NLT or LT suicide attempt. The results are discussed in relation to previous findings on suicidology and to practical implications in correctional settings.     

Suicide attempt and self-mutilation among Turkish high school students in relation with abuse,neglect and dissociation

A questionnaire consisting of items about abuse, neglect, self-mutilation and suicide attempt and the Turkish Version of the Dissociative Experiences Scale were given to 862 high school students. The rates of suicide attempt and self-mutilative behaviors were 10.1% and 21.4%, respectively. Abused or neglected groups (34.3%) had 7.6-fold higher suicide attempts and 2.7-fold higher self-mutilation behaviours. The logistic regression model showed that each type of trauma and dissociation contributed to suicide attempts and self-mutilation, but dissociation was the most powerful. Suicidal and self-destructive adolescents should precisely be evaluated for abuse, neglect and dissociation in clinical practice.     

Suicide and other causes of death in a five-year follow-up of patients treated for self-poisoning in Oslo

This 5-year follow-up study includes all patients (n = 934; 50% females) treated for self-poisoning in Oslo during 1 year. Seventeen percent were considered suicide attempts upon admission, 25% among the nonabusers and 8% among the abusers. At follow-up, 122 patients were dead (61% males). The mortality rate was highest among the abusers. The mortality rate was similar (13%) among those who were considered to be suicidal on admittance and those who were not. The causes of death were suicide (28%), opiate abuse (16%), heart disease (14%), accidents or wounds (11%), alcoholism (9%) and others (22%). The standard mortality rate was highly increased in all groups (8 times on average), highest among the female opiate abusers, whose rate was 63 times higher than expected. The increased suicide rates (87 times for females, 27 times for males), however, may be a more relevant measure of mental morbidity than the standard mortality rate. Logistic regression analysis demonstrated that male sex, age above 50 years and the lowest social group were factors on admission associated with death in the follow-up period. Age above 50 years and suicidal attempt on admission were associated with subsequent suicide. The study strongly supports the idea of self-destructiveness and slow suicide in substance abuse.     

Characteristics of Suicide Attempts Preceded by Alcohol Consumption

Acute alcohol ingestion and alcohol dependence are known to increase the risk of impulsive suicide attempt even in non-depressed patients. The relation between alcohol and suicide risk needs, however, to be clarified. We assessed for this purpose prevalence of recent alcohol intake among suicide attempters and compared suicide attempts preceded (“Alcohol + ”) or not by alcohol intake. We included 160 patients examined in the emergency service of a French general hospital after a suicide attempt. Psychiatric disorders were identified according to the DSM-IV criteria. Patients were rated for depression and alcohol use disorder (MAST). Prevalence of alcohol consumption was 40%. Patients from the “Alcohol + ” group were significantly older (40 versus 34.8 years, p = 0.03). Alcohol abuse was more frequent among suicide attempters with prior alcohol ingestion (49% versus 12%,). Alcohol dependence was also more frequent in the “Alcohol + ” group (43% versus 9%). Patients from the “Alcohol + ” group drank more alcohol each day (6.1 versus 1.3 drinks) and more often during the week (3.6 days per week versus 1.4). They had a higher number of alcohol intoxications each week (0.9 versus 0.3). They drank more often alone (41% versus 12%, p < 0.005) and in the morning (21% versus 3%). They had higher scores on the Michigan Alcohol Screening test (14.8 versus 2.9). Prevalence of drug dependence was higher in the “Alcohol + ” group (21% versus 3%, respectively). Suicide attempts must be asked about their recent alcohol intake. This alcohol intake is often the symptom of an alcohol abuse or dependence disorder.
