Effect of psychiatric intervention in attempted suicide: a controlled study

Veterans' satisfaction and perspectives on helpfulness of the Veterans Crisis Line

OBJECTIVE

Crisis hotlines are an important part of a public health approach to suicide prevention. The Veterans Crisis Line (VCL) provides hotline services to Veterans. There is a paucity of research concerning the effectiveness of the VCL. The current work describes efforts to establish groundwork for VCL effectiveness research.

METHODS

155 VCL users who were referred to a Veterans Affairs Medical Center Suicide Prevention Team completed interviews including open-ended and closed-ended questions. Outcomes are reported for suicidal participants, non-suicidal participants, and those who had emergency intervention. Thematic analysis was used for open-ended questions.

RESULTS

Eighty-seven percent of interviewees expressed satisfaction with the VCL, 81.9% reported that the VCL was helpful, and 72.9% said that the VCL helped keep them safe. Of those with suicidal thoughts, 82.6% said the contact helped stop them from killing themselves. Themes are described concerning user identified reasons for VCL contact, most and least helpful aspects of the contact, and suggestions for improvement.

DISCUSSION

This project demonstrates that this group of people who used the VCL overwhelmingly finds the service to be helpful and a barrier to suicide. Further, implications of user feedback for application to VCL operations and future research are discussed.

Attempted suicide and psychiatric consultation

This study investigated the differences in clinical characteristics between suicide attempters referred or not referred to psychiatric consultation after a suicide attempt and factors affecting such referral to psychiatric aftercare after attempted suicide. All 1198 consecutive suicide attempters treated in hospital emergency rooms in Helsinki during a 12-month period were identified. Data were gathered on any psychiatric consultation after the attempt and on all health care contacts 1 year before and after the index attempt. We found that half of the suicide attempters who were not referred to psychiatric consultation were without any aftercare recommendation and treatment contact soon after their attempt. Factors predicting referral to psychiatric consultation were age, psychotic disorder, lack of substance use disorder and, most strongly, the hospital where the suicide attempt was treated. Although the characteristics of a patient attempting suicide do play a role in determining whether a psychiatric consultation will take place or not, the most important factor is the consultation practices of the particular hospital. This in turn influences the probability of adequate aftercare.

Meta-analysis of suicide rates among people discharged from non-psychiatric settings after presentation with suicidal thoughts or behaviours

OBJECTIVE

To quantify the suicide rate among people discharged from non-psychiatric settings after presentations with suicidal thoughts or behaviours.

METHOD

Meta-analysis of studies reporting suicide deaths among people with suicidal thoughts or behaviours after discharge from emergency departments or the medical or surgical wards of general hospitals.

RESULTS

A total of 115 studies reported 167 cohorts and 3747 suicide deaths among 248 005 patients during 1 263 727 person-years. The pooled suicide rate postdischarge was 483 suicide deaths per 100 000 person-years (95% confidence interval (CI) 445-520, prediction interval (PI) 200-770) with high between-sample heterogeneity (I²  = 92). The suicide rate was highest in the first year postdischarge (851 per 100 000 person-years) but remained elevated in the long term. Suicide rates were elevated among samples of men (716 per 100 000 person-years) and older people (799 per 100 000 person-years) but were lower in samples of younger people (107 per 100 000 person-years) and among studies published between 2010 and 2018 (329 per 100 000 person-years).

CONCLUSIONS

People with suicidal thoughts or behaviours who are discharged from non-psychiatric settings have highly elevated rates of suicide despite a clinically meaningful decline in these suicide rates in recent decades.

Deliberate self-harm

Aims and Method

A repetition after 5 years of a prospective case note audit, looking at the impact of a recently established deliberate self-harm (DSH) assessment team on the quality of DSH assessments at Kettering general hospital.

Results

Aspecialist DSH team achieved improvement in the quality of psychiatric assessments for the majority of patients who harmed themselves. Assessments of mental state by accident and emergency (A & E) and medical staff before referral to the psychiatric team remain problematic.

Clinical Implications

Setting up aspecialist team to assess patients who harm themselves can improve the quality of the psychiatric care they receive, but emphasis must still be placed on an adequate assessment of mental state by medical and nursing staff in A&E and on medical wards.

Three-year mortality rate of suicide attempters in consultation-liaison service

OBJECTIVE

Suicide attempters might be sent to the emergency room for urgent medical intervention. Some with more severe physical morbidity may be hospitalised, and psychiatrists might be consulted for suicide evaluation. The aim of our study was to investigate the three-year all-cause mortality rate of hospitalised suicide attempters with regard to the effect of consultation-liaison services, and to identify any risk factors associated with mortality.

METHODS

Between 2002 and 2006, 196 inpatients from medical or surgical wards in a general hospital who had consulted psychiatrists because of suicide attempts were collected consecutively. We traced their mortality incidence during a three-year period, and calculated the mortality rate and time (days) to death.

RESULTS

Three-year all-cause mortality was 20.4%, and there was a higher risk of mortality in the first two years after the index suicide attempt. In the adjusted Cox regression model, associated risks included male gender, older age, diagnosis of depressive disorders and lack of psychiatric follow-up.

CONCLUSIONS

We found that hospitalised suicide attempters had higher all-cause mortality after discharge, and determined that psychiatric follow-up is helpful. More attention should be paid to those with potential risk factors, and timely intervention is suggested in order to reduce mortality.

Adolescents with suicidal behaviour: attendance at A&E and six month follow-up

Objectives: To review the clinical presentation, and Accident and Emergency Department clinical response to 14-20 year olds in suicidal crisis in inner city Dublin and to carry out a six month follow up of these young people.

Method: A retrospective review of the case notes of all 14-20 year olds who had attended the Mater Hospital A&E department between June 2001 and May 2002 with suicidal behaviour or ideation was carried out in order to establish socio-demographic information, type of suicidal or self-harming behaviour, intervention in the A&E department, and discharge plan. Active outreach attempts were made to trace, contact and interview these young peoples at least six months after the initial presentation. Quantitative measures of psychological functioning at follow-up included the General Health Questionnaire, The Beck Depression Inventory and The Scale for Suicidal Ideation. A qualitative interview covered their recall of the reasons for their deliberate self harm, their view of their current psychological functioning and personal relationships, reported repetition of deliberate self harm, and their views of what type of services would be useful for young people with suicidal ideation or behaviour.

Results: A total of 89 young people aged 14-20 years (male: female ratio = 2:3) presented to the Mater A&E department between June 2001 and May 2002 with deliberate self-harm, deliberate self-poisoning and/or suicidal ideation, and accounted for 108 presentations. They showed high levels of psychosocial disadvantage. Almost half had a history of previous contact with mental health services, while the same proportion had a history of previous deliberate self-harm. Drug overdose using paracetamol was the most common method used. Psychiatric assessment was documented in 66% of cases, and documented follow up recommendations were made in 60% of cases. Two thirds of the 89 young people who formed the study population were traced. Half of those contacted agreed to be interviewed and half refused. The majority of those interviewed described themselves as functioning better psychologically than at the time of the index attendance at the A&E department The quantitative measures supported this. One third of those interviewed reported repeated deliberate self-harm since their index attendance, for which most did not seek medical intervention. Many of the young people had clear views about the importance of talking to someone when in crisis. They described a service, which was informal, accessible on a 24-hour basis, and staffed by people with experience of mental health, alcohol and drug related disorders.

Conclusions: This is a particularly vulnerable group of patients from a socio-demographic and mental health perspective. Their attendance at the A&E department provides a unique opportunity for an in-depth psychosocial assessment, which should be recorded in a systematic way to assist clinical audit, facilitate strategic mental health planning and may confer some therapeutic clinical benefit to at risk young people. An easily accessible, active DSH team specifically tailored for young people in the A&E department could provide assessment and short-term follow-up. This is the approach recommended by young people in suicidal crisis, whose views need to be heard.

Risk and predictors of suicide and non-suicide mortality following non-fatal self-harm in Northern Taiwan

OBJECTIVE

To investigate the risk and predictors of suicide and non-suicide mortality after self-harm in a Taiwanese population.

METHOD

Between July 2006 and June 2008, 3,299 individuals who harmed themselves were recruited to a population-based self-harm register in Taoyuan County, Taiwan. They were followed until December 2008, with record linkage for date and cause of death in a national mortality database.

RESULTS

In total, 115 individuals died, 52 through suicide. The risks of suicide and non-suicide mortality in the first year were 1.5 and 2.2%, respectively, representing an approximately 75-fold and 5-fold age- and gender-standardized increase compared with the general population in Taiwan. Male gender, rural residence, more lethal methods of self-harm and self-cited stressors for the index self-harm episode (unemployment, and chronic somatic illness) were independent risk factors for suicide mortality. Male gender, older age, rural residence and more lethal methods of self-harm were also independent risk factors for non-suicide mortality. The association between of unemployment as a cited reason for self-harm and later suicide was strongest in men and in those aged more than 45 years.

CONCLUSIONS

Relatively high rates of suicide and non-suicide mortality were found following self-harm. Suicide prevention needs to take into account of risk factors for fatal repetition of self-harm.

Mortality and suicide after self-harm: community cohort study in Taiwan

BACKGROUND

Little is known about outcomes after self-harm in East Asia.

AIMS

To investigate mortality after self-harm in a Taiwanese population.

METHOD

Between 2000 and 2003, 1083 individuals who self-harmed were identified through a population self-harm register in Nantou County, Taiwan, and followed until 2007 for date and cause of death on a national mortality database.

RESULTS

In total, 145 individuals died, 48 through suicide. The risks of all-cause and suicide mortality in the first year were 4.7% and 2.1% respectively, representing 8- and 131-fold age- and gender-standardised increases. Male gender and older age were independent risk factors for both suicide and non-suicide mortality. Use of more lethal methods in the index episode was associated with higher mortality but this was accounted for by gender.

CONCLUSIONS

Results in this sample support the recommendation that people with a history of recent self-harm should be a major target for suicide prevention programmes.

The attitudes of emergency staff toward attempted suicide patients: a comparative study before and after establishment of a psychiatric consultation service

BACKGROUND

The staff in the emergency room of general hospitals are under heavy work pressure and seem to reveal negative attitudes toward suicide attempters. From earlier studies there is indirect evidence that the attitudes of staff who have the opportunity to consult a psychiatrist are less negative.

AIMS

The study compare the attitudes of emergency room staff in a general hospital toward patients who had attempted suicide before and after establishment of a psychiatric consultation service.

METHODS

Attitudes were measured on the Understanding Suicidal Patients (USP) Scale. A total of 100 participants returned the questionnaire.

RESULTS

General understanding and willingness to nurse patients who attempted suicide did not increase.

CONCLUSION

The results suggest that providing a psychiatric consultation service did not significantly affect attitudes among general hospital emergency room staff toward attempted suicide patients during its first year of operation, but in general, the emergency room staff was content with the opportunity for psychiatric consultation.

The role of parental bonding and early maladaptive schemas in the risk of suicidal behavior repetition

The current study examined the role of perceived parental bonding and early maladaptive schemas in suicidal behavior. Participants completed measures of perceived parental bonding; schemas; risk of repeating suicidal behavior; anxiety; and depression following their presentation at Accident and Emergency with suicidal behavior. A suicidal behavior group (n = 60) differed from a comparison clinical (n = 46) and non-clinical (n = 48) group on measures of early maladaptive schemas, anxiety, and depression. No significant difference was noted between the suicidal behavior group and the comparison clinical group on a measure of parental bonding. Within the suicidal behavior group, significant associations were indicated between perceived parental bonding and risk of repetition of suicidal behavior; and early maladaptive schemas and risk of repetition of suicidal behavior. Early maladaptive schemas were found to mediate the relationship between perceived parental bonding and risk of repetition of suicidal behavior, with schemas of Social Alienation and Defectiveness/Shame offering mediator roles. The findings of the current study emphasize the complexities of suicidal behavior and factors that are associated with suicidal behavior. Although causality cannot be assumed, the findings highlight the importance and inter-relationships of not only perceived early experiences, but of underlying schemas in relation to suicidal behavior.

Suicide attempt and n-3 fatty acid levels in red blood cells: a case control study in China

BACKGROUND

Epidemiologic studies show that low fish intake is a risk factor of suicidality; however, there are no case-control studies investigating suicide attempt risk and tissue n-3 fatty acid levels.

METHODS

We recruited 100 suicide-attempt cases and another 100 control patients injured by accidents who were admitted to three hospitals affiliated with Dalian Medical University in Dalian, China. Case and control subjects were matched for age, gender, and smoking status. Those who were inebriated at the time of hospitalization were excluded. Blood was sampled immediately after admission to a hospital. Washed red blood cells (RBCs) were obtained, and the fatty acid composition of the total RBC phospholipid fraction was analyzed by gas chromatography.

RESULTS

Eicosapentaenoic acid (EPA) levels in RBC in the case subjects were significantly lower than those of the control subjects (.74 +/-.52% vs. 1.06 +/-.62%, p <.0001). When the highest and lowest quartiles of EPA in RBC were compared, the odds ratios of suicide attempt was.12 in the highest quartile (95% confidence interval:.04-.36, p for trend =.0001) after adjustment for possible confounding factors

CONCLUSIONS

Our findings suggest that low n-3 fatty acid levels in tissues were a risk factor of suicide attempt. Further studies including intervention with fish oil are warranted.

Fatal and non-fatal repetition of self-harm. Systematic review

BACKGROUND

Non-fatal self-harm frequently leads to non-fatal repetition and sometimes to suicide. We need to quantify these two outcomes of self-harm to help us to develop and test effective interventions.

AIMS

To estimate rates of fatal and non-fatal repetition of self-harm.

METHOD

A systematic review of published follow-up data, from observational and experimental studies. Four electronic databases were searched and 90 studies met the inclusion criteria.

RESULTS

Eighty per cent of studies found were undertaken in Europe, over one-third in the UK. Median proportions for repetition 1 year later were: 16% non-fatal and 2% fatal; after more than 9 years, around 7% of patients had died by suicide. The UK studies found particularly low rates of subsequent suicide.

CONCLUSIONS

After 1 year, non-fatal repetition rates are around 15%. The strong connection between self-harm and later suicide lies somewhere between 0.5% and 2% after 1 year and above 5% after 9 years. Suicide risk among self-harm patients is hundreds of times higher than in the general population.

Assessment and treatment of the youthful suicidal patient

In this review, a framework for the assessment of suicidal risk in the adolescent is described, based on existing epidemiological and clinical studies. The assessment of risk can then be used to determine the immediate disposition, intensity of treatment, and level of care. Furthermore, the assessment of psychiatric and psychological characteristics of the individual and family, as well as the motivation and precipitants for the suicidal episode, can be used to target areas of vulnerability and thereby help the patient reduce the risk of recurrent suicidal behavior. The approach to treatment, guided by the assessment, uses a model of suicidal behavior that is based on our clinical experience and the few extant clinical trials of the treatment of suicidal behavior. Recommended interventions involve treatment of psychopathology; amelioration of cognitive distortion and difficulties with social skills, problem-solving, and affect regulation; and family psychoeducation and intervention. Given the chronic and recurrent nature of the conditions associated with adolescent suicide attempts, a long-term care plan involving both continuation and maintenance treatment is advocated. Further research is necessary to identify the most effective approaches to the treatment of adolescent suicide attempters.

Deliberate self-harm in children: the nurse's therapeutic style

This article examines child health nursing skills in the management of deliberate self-harm in children and young people. In order for education to be effective (i.e. so that it changes practice) it must address the belief systems of the practitioner. It is suggested that such belief systems are embedded in collectively held tribal stories. The more challenging the patient's behaviour, the more powerful the influence of the tribal narrative--possibly as a defensive strategy. The authors outline strategies aimed at increasing the range and depth of the therapeutic response to episodes of self-harm, and outline nursing interventions in the management of self-harming children.

Patients who attempted suicide and failed to attend mental health centres

Different studies report non-attendance to treatment of between 20 to 70% of patients after a suicide attempt. However, few studies have analyzed the characteristics of this non-attending population. To determine therefore the characteristics or profile of individuals who do not attend outpatient centres to which they are referred after a suicide attempt, we performed this study. A total of 232 patients who had attended the Emergency Department of our general hospital were interviewed. Instruments used included the suicide risk scale, the violent behaviour scale, the impulsivity scale, the hopelessness scale, and the Beck's depression scale. Seventy-three percent of the sample did not attend the mental health centre to which they had been referred. In comparison to the attending group, the non-attending group had the following characteristics: unmarried, residing in an urban area, took less precautions not to be discovered, were more critical of the attempt, and the purpose of the attempt was to resolve a conflict. Our data emphasize the importance of social and interpersonal aspects in determining the nature of the psychiatric care required by these types of patients.

An exploration of psychiatric nurses' and patients' opinions regarding in-patient care for suicidal patients

This study explores psychiatric nurses' and patients' opinions regarding the care provided for in-patients who were admitted following: (i) depression as a result of psychosocial difficulty, (ii) suicidal ideation, or (iii) an overt suicidal behaviour. It also explores how care for such patients could be improved. A total of 20 psychiatric nurses and 17 in-patients were interviewed. The results show that nurses and patients believe that communicating with patients about their difficulties is the most important skill in psychiatric nursing. Most nurses were disappointed with the limited time they had available to communicate with patients and they were constructively critical of their pre-registration training in communication skills. Patients suggested that nurses should spend more time in helping to problem-solve their difficulties. Both nurses and patients suggest that situational factors impinge on the time available for psychotherapeutic care. Findings have implications for pre- and post-registration education and practice. Responses from both cohorts suggest how care could be improved.

Mortality after deliberate self-poisoning. A prospective follow-up study of 587 persons observed for 5279 person years: risk factors and causes of death

A follow-up study of mortality and factors associated with death from various causes were done on two unselected groups of patients surviving deliberate self-poisoning in 1978 and 1987. The persons were studied up to the end of 1993. In 1978 the group included 152 female and 101 male subjects and in 1987 the group included 190 female and 144 male subjects. By the end of 1993 a total of 37 (24%) of the female and 33 (33%) of the male patients admitted in 1978 had died (n.s.) and 18 (10%) of the female and 29 (20%) of the male patients admitted in 1987 had died (P < 0.01). The main causes of death were suicide and death from cardiovascular disease. The 5-year follow-up mortality more than doubled in males from 1978 to 1987 but decreased in females. In female subjects, the total follow-up mortality was 3.6 times the expected ratio, with a 95% confidence interval (95% CI of 2.7-4.6); in male subjects it was 5.0 times the expected ratio (95% CI = 3.8-6.4). The cause-specific mortality ratio was highest for deaths from suicide--in the female group it was 65.5 (39.4-102.3) times the expected and in the male group 41.5 (26.0-62.8)--and from accidental poisoning--for females 50.0 (6.1-180.6) times the expected and for males 66.7 (24.5-145.1). In the female group none of the variables examined reached significance as predictors for subsequent suicide or death from unnatural causes. In the male group being aged 30 years or more came out as a predictor for subsequent suicide [relative risk (RR) = 5.66 (1.05-30.37)], while imprisonment came out as a protective factor [RR = 0.08 (0.01-0.64)]. Significant predictors for death from unnatural causes were: having been convicted (but not been in jail) [RR = 34.01 (1.07-1078.15)] and a serious suicidal intent [RR = 138.62 (1.38-13,946.79)]. It is concluded that patients who survive deliberate self-poisoning are at increased risk of death. The predictors for death are not very specific and are considered difficult to apply in the clinical work with these patients.

The aftercare of adolescents with deliberate self-harm

The evaluation and aftercare of the adolescent suicide attempter is described. The assessment of suicidal risk is aimed at the identification of those factors present in the patient and environment that make repetition of suicidal behavior likely. These factors, along with the motivation and precipitant for the suicide attempt, are used to determine the intensity of care and targets of treatment. Important elements of treatment include: obtaining a no-suicide contract, addressing potential sources of noncompliance, determining proper intensity of treatment, provision of family psychoeducation addressing ongoing family difficulties, treatment of co-occurring psychopathology, and remediation of social skills and problem-solving deficits.

Suicide rate following attendance at an accident and emergency department with deliberate self harm

OBJECTIVE

To determine the risk of suicide in patients attending an accident and emergency (A&E) department with deliberate self harm.

METHODS

Information was obtained on suicides and open verdicts from the coroner's office and cross checked with computerised records in the A&E department.

RESULTS

There was a trend to suicide among younger socially isolated males and older females.

CONCLUSIONS

There is a significant association between suicide and a previous attendance at A&E with deliberate self harm. Appropriate assessment of these patients is an efficient way of managing self harm.

Differences between general practices in hospital admission rates for self-inflicted injury and self-poisoning: influence of socioeconomic factors

BACKGROUND

Self-inflicted injury and self-poisoning are major causes of hospital admission of young adults throughout the United Kingdom, while in Scotland, suicide is the leading cause of death each year in persons aged 15 to 40 years. General practitioners are in a unique position in that they may have contact with the patient before the attempted suicide and later play a supportive role along with other health service and social work professionals.

AIM

This study set out to examine the differences between 72 general practices in Tayside in the hospital admission rates for self-inflicted injury/poisoning among their patients, and the extent to which these differences were related to the socioeconomic conditions prevailing in the patients' areas of residence and in the areas in which practices were located. The study also aimed to examine the agents of self-inflicted injury/poisoning most commonly used by different age groups.

METHOD

Details of admissions to hospitals in Tayside for self-inflicted injury/poisoning, from 1991 to 1993 inclusive, were obtained from a national, hospital inpatient discharge summary scheme, loaded onto a microcomputer and analysed using standard commercial software. Data from the 1991 census at the postcode sector level and death registrations summaries were obtained from the office of the registrar general for Scotland. The deprivation categories used were based on 1991 census data.

RESULTS

In the study period, 52% of hospital admissions for self-inflicted injury/poisoning were of patients aged 30 years or over. Overall, the number of admissions of females exceeded that of males by 26%. Annual hospital admission rates for self-inflicted injury/poisoning per 1000 registered patients averaged over the Tayside practices correlated closely with the male unemployment rate in, and deprivation category of, the postcode sector in which the practice was located. Rates ranged from an average of 1.1 admissions per 1000 registered patients per year in sectors with less than 5% male unemployment of 4.6 where male unemployment was 15% or over. Similarly, the admission rates ranged from 1.1 per 1000 registered patients per year in the most affluent sectors to 3.3 in the most deprived sectors. The proportion of older patients who used sedatives, hypnotics and tranquillizers to poison themselves was greater than that of younger patients; analgesics, such as paracetamol, were the agents most commonly used for self-poisoning by the younger age groups.

CONCLUSION

The routine monitoring at national level of hospital admission rates for self-inflicted injury/poisoning, using established computerized information systems, would enable the identification of those practices that have a relatively high proportion of such admissions. This would provide a starting point for the identification of pilot sites for the development of protocols for offering multi-agency support to high-risk groups of patients.

Outcome of deliberate self-poisoning. An examination of risk factors for repetition

BACKGROUND

One of the most important outcomes following an episode of non-fatal deliberate self-poisoning is its repetition.

METHOD

In a prospective follow-up study the subjects were 992 people responsible for 1096 consecutive episodes of deliberate self-poisoning recorded at a teaching hospital accident and emergency department. Risk factors examined were socio-demographic variables, psychiatric and self-harm history, aspects of the self-poisoning episode, and appearance and behaviour at accident and emergency; the frequency of each was compared between those patients who repeated within one year (n = 116) and those who did not (n = 876).

RESULTS

Those who repeated were more likely to have ingested more than one drug, to report a previous episode of self-poisoning, to be aged 25-54, and to have experienced previous psychiatric care or psychiatric admission. They were less likely to be in paid employment, or to have expressed a threat to another person or written a note. The best predictor--previous psychiatric contact--only had a positive predictive value of 21% (95% confidence interval 16-25%).

CONCLUSIONS

Risk factors for repetition of self-poisoning should be kept up-to-date despite modest predictive power. More attention might be paid to clinical rather than socio-demographic aspects of self-harm.

Cognitive predictors of suicide risk among hospitalized psychiatric patients: a prospective study

This prospective study examined the utility of several cognitive variables as predictors of suicide risk among 79 hospitalized psychiatric patients. These variables included pessimism (measured by the Hopelessness Scale), perceived and actual problem-solving ability (indexed by the Problem-Solving Inventory and Means-End Problem-Solving test, respectively), and polarized thinking, self-negativity, and construct system constriction and differentiation (derived from a repertory grid). Suicide risk was operationalized in terms of subsequent self-report of suicide ideation and staff records of time spent on suicide precautions. Results indicated that hopelessness, self-negativity, and poor problem-solving performance functioned as reliable predictors of suicide risk, whereas self-evaluated problem-solving ability did not. Interestingly, constriction emerged as a significant inverse predictor across.

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.

Outcome of attempted suicide and psychiatric consultation: risk factors and suicide mortality during a five-year follow-up

A total of 1018 self-poisoned patients were treated during the year 1983 in the emergency room of Helsinki University Central Hospital. By the end of a 5-year follow-up period, 3.2% of these had committed suicide, making annual suicide mortality 589 per 100,000. During the first year after the index attempt, suicide mortality was 1768 per 100,000, a 50-fold risk compared with that of the total population in Helsinki. Risk factors were being male of advancing age, having mental disorders, previous suicide attempts, a nonimpulsive index suicide attempt, moderate to very serious lethality and severe intention to die during the index suicide attempt. When the lethality was assessed as being very serious or intention to die as certain, 21% later committed suicide. The relative risk for those left without psychiatric consultation was 0.6 when the lethality was mild and 1.6 when it was severe. Results indirectly indicate that psychiatric consultation seemed to have a positive effect on the outcome of these attempted suicides.

Self-poisoning patients discharged from accident and emergency: risk factors and outcome

In a prospective audit of 1,096 consecutive attendances by deliberate self-poisoning patients at an accident and emergency department (A&E), such patients were discharged directly from A&E on 31% of occasions. Outcome and risk were compared for patients admitted to hospital and discharged directly from A&E. In the following year repetition of self-poisoning occurred in the same proportions of patients admitted to hospital and discharged from A&E (12%, relative risk 1.02). Suicide during the following three years occurred in 1.3% of patients admitted and 1.1% of those discharged (relative risk 1.2). Patients admitted to hospital from A&E were those likely to be at greater risk: they were older, reported more physical ill-health, expressed a threat or left a note more often, and had more frequently experienced psychiatric inpatient care. Thus, nearly one-third of deliberate self-poisoning attenders were discharged from A&E; outcomes were similar despite higher risk among admitted patients, suggesting that brief admission has some benefit.

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.

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.

Self-harm patients not admitted to hospital

In recent years a large proportion of self-harm patients attending hospital have not been admitted to medical or short-stay wards but have returned home directly from accident and emergency departments. A continued trend towards such a policy seems likely despite limited and conflicting evidence on its desirability. The clinical, training and epidemiological implications of changes in self-harm admission policy are outlined, together with recommendations concerning clinical audit.

To which neurotic patients do psychiatrists prescribe medication?

Of 318 newly referred neurotic patients, 43% were prescribed medication by their psychiatrist. Medication was more likely to be prescribed to patients who are older, who are married, who have lengthy illnesses and who do not have a history of deliberate self-harm. These findings are discussed in the context of current debate about optimal treatment methods for patients with neurotic disorders.

Prevention of suicide

We reviewed the epidemiologic features of suicide in Canada and evaluated suicide prevention programs. Three groups were found to be at increased risk for suicide: men aged 70 years or more, women aged 65 to 69 and men aged 20 to 24. The other groups, in decreasing order of risk, were the mentally ill, people who have attempted suicide, those with a life-threatening illness, native people, people with a family history of suicide and prisoners. Studies that evaluated suicide prevention programs showed that none significantly reduced the incidence of suicide; however, the studies were found to be methodologically inadequate or used noncomparable systems of data collection. On the basis of our findings we recommend that primary care physicians routinely evaluate suicide risk among patients in high-risk groups and that intervention include counselling, follow-up and, if necessary, referral to a psychiatrist. Close follow-up is recommended for newly discharged psychiatric patients and those who recently attempted suicide.

General hospital admission in the management of parasuicide. A randomised controlled trial

Suitably trained junior doctors selected parasuicides with no immediate medical or psychiatric treatment needs on initial assessment in a casualty department. This group was then randomly allocated to hospital admission (38 cases) or discharge home (39 cases). One week later there were no significant differences between groups on diverse outcome measures, including repetition rate, psychological symptoms, and social functioning. A second follow-up using the same measures at 16 weeks also failed to demonstrate any differences between groups, both of which showed considerable overall improvement. A parasuicide management policy consisting of assessment in a casualty department and selective discharge was appropriate for 15% of a hospital-referred population. This lends support to recent government recommendations, but caution should be exercised before such a result is generalised.

Repeat self-harm: an 18-month follow-up

An 18-month follow-up of cases of deliberate self-harm (DSH) revealed that 30% had repeated the act. Of a large number of items recorded at index DSH only one, a past history of self-harm, was associated with repetition. It is suggested that some factors not predictive of longer term repeat DSH may be important in the assessment of risk for immediate further self-harm.

Evaluation of suicide risk among youths in community settings

Identifying youths in imminent danger of suicide and in need of emergency psychiatric services is a difficult task. Although clinicians have often described the psychiatric profile of youths at risk for suicide, there is little empirical evidence of successful strategies for identifying suicidal risk. Researchers are faced with a number of problems when attempting to validate risk evaluation procedures: Suicide risk profiles vary with age and developmental stage; there appear to be several patterns or subtypes of suicidal patterns; suicidality depends on one's current emotional state; evaluators are likely to be biased in the direction of over-estimating risk and are not likely to have extensive clinical training; imminent danger for suicide is time-limited; and a youth's risk will depend on surrounding environmental stressors and supports. These considerations force researchers to assume a strategic approach in defining levels of suicide risk and imminent danger of suicide. An example of a potential strategy for identifying risk among youths is outlined in this chapter. Although this strategic approach appears useful, researchers continue to be faced with major problems in validating such procedures. Determining the predictive validity of potential suicide screening procedures requires researchers to evaluate and to follow longitudinally a large sample of youths, while deliberately refraining from intervening to help those youths who appear to be in crisis.

Suicide: a guide to risk factors, assessment, and treatment of suicidal patients

This article summarizes what is known about risk factors for suicide in both adolescent and adult populations. It also translates this knowledge base into practical considerations for the physician on the assessment and treatment of suicidal patients. Since most patients who commit suicide have seen a physician in the weeks to month prior to their deaths, and many kill themselves with medications prescribed by their doctors, the physician's early detection and treatment of suicidal behaviors and associated psychiatric disorders in his or her patients becomes a major suicide prevention strategy.

Who commits suicide after a suicide attempt? An 8 to 10 year follow up in a suburban catchment area

One hundred and sixty-three individuals in a suburban catchment area of 72,000 inhabitants made registered suicide attempts during 1975-1976 (i.e. 159/100,000 greater than or equal to 18 years). They were followed up by means of the Swedish Register of Death Causes over a period of 8-10 years. Police reports, autopsies and psychiatric records were also studied. Six cases of verified suicide were found and four additional cases were considered as probable or possible suicides. Thus the cumulative rate over 8-10 years was 3.7-6.1%. There was a mean number of 3.5 suicide attempts before the eventual suicide. The most important common factor overall was alcohol or drug abuse with social deterioration (seven in 10 cases). The rest (three in 10 cases) were depressed women with long-standing suicidal processes. The importance of recognizing chronic abuse as probably the most important background factor is stressed. The total group encompasses individuals with longstanding and severe life problems and difficulties in relating to society. The realistic chances of being able to provide effective suicide prophylaxes for most of these patients requires well planned and longstanding treatment and rehabilitation programmes.

Suicide, and other causes of death, following attempted suicide

The number of deaths in a large series of suicide attempters followed up after their attempts was 3.3 times greater than expected. Suicide or probable suicide occurred in 2.8% by the end of the eighth year of follow-up, the rate of suicidal deaths being 26.9 times the expected rate. The highest risk of suicide was during the first 3 years, especially in the first 6 months, following an attempt. Factors identified at the time of the attempts which were associated with suicide risk included: being male, advancing age (females only), psychiatric disorder (especially schizophrenia), long-term use of hypnotics, poor physical health, and repeat attempts. Recent disruption of a relationship with a partner and major rows rarely preceded the attempts of those who later killed themselves. Factors predicting long-term risk of suicide also predicted short-term risk. There were more than double the expected number of deaths from natural causes, the excess being greatest in females. Markedly high death rates were found for endocrine, circulatory and respiratory diseases, and accidents.

The impact of a liaison psychiatry service on patterns of referral in a general hospital

A retrospective study of psychiatric referrals from a general hospital inpatient population was carried out for three separate years, 1973, 1976 and 1979. Reorganisation of the liaison service to the responsibility of one consultant team was associated with changes in referral rate and disposal. In particular, there was a significant increase in the referral rate of patients from medical and surgical wards who were not involved in acts of deliberate self-harm.

Evaluation of the effectiveness of suicide prevention programs: a methodological perspective

Many studies that attempt to evaluate the effectiveness of treatment programs for suicidal patients are methodologically deficient in one or more areas. This paper outlines six criteria that should be met in designing such investigations: Patients should be randomly assigned to groups; at least 80% of the subjects who were initially enrolled should be followed up; the results should be both statistically significant and clinically important; all clinically relevant outcomes should be reported; the patients must be adequately described; and the new intervention should be feasible in other settings. It is shown that these criteria are both necessary and achievable.

Parasuicides in a general hospital psychiatric unit: their demographic and clinical characteristics

This study presents a profile of 89 patients admitted to the psychiatric unit of a general hospital for a deliberate but not fatal self-inflicted injury. The role of selected demographic clinical and psychosocial characteristics in the hospital admission of these parasuicide patients and their use of available services during the acute phase of their period of distress are discussed.

Management of the repeatedly suicidal patient

Although repetitive suicidal behaviour is commonly encountered, a relatively small number of very difficult patients engage in it. These individuals suffer primarily from severe personality disorders, as well as alcoholism and drug abuse. They are at high risk for eventual suicide. Although as a group they receive a great deal of hospital treatment, inpatient management is fraught with difficulties. Extended inpatient treatment is unlikely to be of benefit and may perpetuate the behaviour by leading to regression and excessive dependence on hospitalization. A model of management is described which couples the use of a brief-stay, crisis, inpatient unit and community-based outpatient treatment. Communication between institutions and agencies involved in the patient's care as well as coordination of services is essential. Acceptance by therapists of the risk of suicide and the realistic limitations to meeting these patients' needs can help such patients assume more responsibility and independence.
