A case-control study of 92 cases of in-patient suicides

Lessons for Future Vaccination Policies: COVID-19 Vaccination Intention in People With and Without Chronic Diseases

PURPOSE

This study compared COVID-19 vaccination intentions in those with and without chronic diseases (CDs and non-CDs) in South Korea. We hypothesized that the factors associated with COVID-19 vaccination intentions would differ between CDs and non-CDs in South Korea.

METHODS

Using survey data collected through a Korean online panel in June 2021, we conducted a cross-sectional secondary data analysis. Of the 2292 participants, 411 had at least one chronic disease. To construct a comparable dataset, we selected non-CDs via a 1:1 case-control matching for age and gender. We then utilized a multivariable binary logistic regression model to explore the factors contributing to COVID-19 vaccination intentions in CDs and non-CDs.

RESULTS

All told, over 75% of participants in both groups indicated that they intended to vaccinate against COVID-19. In both groups, those who mistrusted general vaccine benefits reported significantly lower COVID-19 vaccination intentions. Regarding factors associated with vaccination intentions, CDs identified anxiety regarding coronavirus and exposure to COVID-19 vaccination promotions at the community level, while non-CDs highlighted hesitancy regarding vaccines and confidence in government/health services.

CONCLUSION

Improving vaccination acceptance will require the development and implementation of tailored approaches for CDs and non-CDs and efforts to minimize general vaccine mistrust.

Predictors of inpatient suicide in an Irish psychiatric service, a longitudinal case-control study

OBJECTIVE

Inpatient suicide remains difficult to predict. This study aimed to identify individual patient predictors to help identify those at greater risk.

METHODS

This case-control study was undertaken in an independent mental health service in Ireland. Cases were drawn from all admissions to the service between March 2004 and February 2019. Controls were matched for date of admission. Univariate and multivariate analyses were conducted.

RESULTS

Thirty-three cases of inpatient suicide were compared to 132 controls. The inpatient suicide rate was 76.2 per 100,000 admissions. The rate of inpatient suicide fell in line with national rates despite less restrictive practices being implemented in the service. Males accounted for 66% of cases. Hanging was the most common method of suicide overall and among male patients, and drowning was the most common among females. Male gender, tertiary referral, an adverse psychosocial event during admission, a period of absence without leave and expressing hopelessness were identified as independent risk factors for inpatient suicide. Substance use, involuntary detention, family history of suicide, and number of previous admissions were not significant.

CONCLUSIONS

While not highly sensitive, a period of absence without leave, tertiary referral and hopelessness are important predictors of inpatient suicide risk that treating teams should consider in care planning.

Electroconvulsive Therapy and Akathisia: A Comprehensive Literature Review of Case Reports

ABSTRACT

This review aimed to investigate the effects of electroconvulsive therapy (ECT) on akathisia. We systematically searched MEDLINE and Embase and included case reports on akathisia caused by or treated with ECT. We identified and included 9 articles. Seven articles, representing 10 cases, reported that akathisia improved after ECT. Most cases (7 cases) were diagnosed with a mood disorder, and all 10 cases were treated with antipsychotics. Akathisia was regarded as tardive (3 cases) and severe (4 cases). Although treatments for akathisia, such as adjusting antipsychotics and adding medication for akathisia, were tried before ECT, ultimately none were effective. In all 10 cases, akathisia showed significant improvement after ECT, and nonantipsychotic psychotropics or low-dose antipsychotics were administered as post-ECT treatment. Two articles (5 cases) reported that akathisia occurred after ECT. Three of these cases were diagnosed with a mood disorder, and all 5 cases were treated with perphenazine and tricyclic antidepressants. Akathisia occurred multiple times after ECT, but it was transient. Despite attempts to manage the akathisia, including discontinuation of psychotropics, addition of medication for akathisia, and adjustment of stimulation electrode positions, the outcomes of the interventions were inconsistent. Nonetheless, no persistent akathisia was observed after the end of the ECT course. Although the effects of ECT on akathisia remain unclear because of the paucity of high-quality studies, ECT could be considered particularly for treatment-resistant, tardive, and/or severe akathisia comorbid with mood disorders. Conversely, clinicians should keep in mind that transient akathisia can develop following ECT.

A comparison of inpatient suicides in Australian psychiatric and non-psychiatric hospital units between 2009 and 2018

Hospitalisation is designed to protect patients from harm; however, patients have been reported to take their own lives during hospital admissions. While a significant healthcare concern, few studies have analysed inpatient suicides in general and psychiatric hospital units. Understanding these deaths is important for informing future prevention initiatives. Here we investigate a national sample (n = 367) of inpatient suicides in general (24%, n = 87) and psychiatric (76%, n = 278) hospital units. Patient characteristics, suicide location, timing, and suicide methods were assessed and compared. Patients who died from suicide were mostly male and admitted into psychiatric units. General hospital patients were less likely to have a known history of mental illness or previous self-harm and were often admitted for mental illness-related presentations. Suicides frequently occurred outside of the hospital by hanging. Patients in psychiatric units were more likely to be on approved leave at their death, and general patients were more likely to have absconded. These results indicate the need to identify risk factors relevant to each setting and address broader system-level factors. Removing obvious ligature points, preventing absconding, and assessing patients before episodes of leave, could contribute to preventing inpatient suicides.

Inpatient suicide in psychiatric settings: Evaluation of current prevention measures

The risk of suicide in psychiatric hospitals is 50 times higher than in the general population, despite patient safety being a priority for any hospital. However, to date, due to the complexity of assessing suicide risk, there has been no consensus on the suicide prevention measures that should be in place in hospitals. The aim of this work is: To provide an overview of the progress that has been made in the field of inpatient suicide prevention in recent years; discuss the problems that remain; and suggest potential future developments. As new clinical dimensions (notably anhedonia, psychological pain and hopelessness) develop, they should become new therapeutic targets. Team training (like the Gatekeeper Training Program) and the latest advances in suicide risk assessment (such as the Collaborative Assessment and Management of Suicidality) should be implemented in psychiatric wards. Suicide prevention plans (e.g., ASSIP, SAFE-T, etc.) represent easy-to-administer, low-cost interventions. The Mental Health Environment of Care Checklist has been proven effective to reduce suicide risk at hospitals. Furthermore, the types of psychotherapy recommended to reduce suicide risk are cognitive behavioral therapy (CBT) and dialectical behavioral therapy (DBT). There are several pharmacological treatments for suicide risk, such as lithium and clozapine, which have been shown to be effective in the long term, as well as ketamine and esketamine, which are more effective in the short term. Following some encouraging recent results, buprenorphine may also be proposed to patients with a suicide risk. Triple chronotherapy rapidly improves depressive symptoms over 9 weeks. Regarding brain stimulation techniques, rTMS has proven to be effective in alleviating multiple dimensions of suicidality.

Is suicidal behaviour a stronger predictor of later suicide than suicidal ideation? A systematic review and meta-analysis

OBJECTIVE

Suicidal ideation and suicidal behaviour are both regarded as important risk factors for suicide, but it is usually believed that suicidal ideation is less strongly linked to suicide than suicidal behaviours. In this study, we assessed and compared the strengths of the associations that suicidal ideation and suicidal behaviour have with later suicide using meta-analysis of primary studies reporting both these independent variables and the dependent variable of suicide.

METHODS

A total of 51 English language publications describing cohort or controlled studies that reported on both the association between suicidal ideation and suicide and the association between suicidal behaviours and suicide were located using searches for titles in PubMed containing variants of the word suicide (suicid*). Suicides were considered to include reported suicides and open verdicts from mortality registers. The strengths of the two associations were examined in separate random effects meta-analyses and were then compared using mixed effects meta-regression. Subgroups were examined according to study characteristics including the definitions of suicidal ideation or behaviour used, setting (psychiatric or non-psychiatric), diagnostic mix of the study population, study design (cohort or control) and study quality.

RESULTS

Suicidal ideation (odds ratio = 3.11, 95% confidence interval = 2.51, 3.86) and suicidal behaviours (odds ratio = 4.09, 95% confidence interval = 3.05, 5.49) were both significantly associated with suicide but there was no significant difference in the strengths of association (p = 0.14). Nor were there significant differences in the strengths of the two associations in multiple subgroup analyses.

CONCLUSION

Suicidal ideation and suicidal behaviour are both moderately associated with suicide. Existing data cannot conclusively demonstrate that suicidal behaviours are more strongly associated with suicide than suicidal ideation. Clinicians should not strongly prioritise suicidal behaviour over suicidal ideation when considering suicide risk.

Meta-analysis of the strength of exploratory suicide prediction models; from clinicians to computers

BACKGROUND

Suicide prediction models have been formulated in a variety of ways and are heterogeneous in the strength of their predictions. Machine learning has been a proposed as a way of improving suicide predictions by incorporating more suicide risk factors.

AIMS

To determine whether machine learning and the number of suicide risk factors included in suicide prediction models are associated with the strength of the resulting predictions.

METHOD

Random-effect meta-analysis of exploratory suicide prediction models constructed by combining two or more suicide risk factors or using clinical judgement (Prospero Registration CRD42017059665). Studies were located by searching for papers indexed in PubMed before 15 August 2020 with the term suicid* in the title.

RESULTS

In total, 86 papers reported 102 suicide prediction models and included 20 210 411 people and 106 902 suicides. The pooled odds ratio was 7.7 (95% CI 6.7-8.8) with high between-study heterogeneity (I2 = 99.5). Machine learning was associated with a non-significantly higher odds ratio of 11.6 (95% CI 6.0-22.3) and clinical judgement with a non-significantly lower odds ratio of 4.7 (95% CI 2.1-10.9). Models including a larger number of suicide risk factors had a higher odds ratio when machine-learning studies were included (P = 0.02). Among non-machine-learning studies, suicide prediction models including fewer risk factors performed just as well as those including more risk factors.

CONCLUSIONS

Machine learning might have the potential to improve the performance of suicide prediction models by increasing the number of included suicide risk factors but its superiority over other methods is unproven.

The Relationship Between Antipsychotic-Induced Akathisia and Suicidal Behaviour: A Systematic Review

OBJECTIVE

We aim to systematically review evidence for a relationship between antipsychotic-induced akathisia and suicidal behaviour, in order to guide further clinical decision making in this area.

METHODS

Several electronic databases (Embase, Medline, Cochrane and PsychINFO) were systemically searched for articles published up to February 2021, using search terms related to akathisia, antipsychotics and suicidal behaviour. Two reviewers independently evaluated all the relevant studies using predetermined criteria and assessed the risk of bias for each included study. The systematic review was conducted in line with PRISMA methodology and reporting.

RESULTS

Following de-duplication, screening and application of exclusion criteria, four eligible studies were identified. All of the available studies were in English and included adult patients. Nevertheless, there was significant variability regarding methodology and overall quality was deemed low due to small sample sizes. There was insufficient data to perform statistical analyses of the results. Of the four studies, two found a weak correlation between antipsychotic-related akathisia and suicidal behaviour, a finding that was not supported by the remaining two studies.

CONCLUSION

The search yielded very few studies for inclusion. On the basis of the existing evidence, akathisia cannot be reliably linked to the presence of suicidal behaviour in patients treated with antipsychotic medication. However, proactive screening for emerging suicidal behaviour in this vulnerable patient group is advisable. Our findings highlight the pressing need for further research in this area.

Absconding During Inpatient Care from a Tertiary Psychiatric Hospital: A Comparative Study

BACKGROUND

Absconding from psychiatric hospitals is of great concern for patients and caregivers. Absconding affects not only the treatment and safety of these patients but also patient's caregivers and the community. Further investigation is needed to examine the pattern of this event and the characteristics of patients who abscond. Hence, our study was aimed to examine the sociodemographic and clinical profiles of inpatients who absconded from a psychiatric hospital in five years and to compare them with matched controls.

METHODS

A retrospective chart review of inpatients who absconded and matched control inpatients during the specified period of five years from January 2014 to December 2018 was done at a psychiatric hospital. Each control was matched with a corresponding absconding case on the following order: (a) admission ward, (b) admission period, (c) diagnosis, and (d) age. Results: Among 20,052 adult admissions during the specified period, 38 patients absconded, with a rate of 1.8 per 1,000 admissions. Most of them were male, from a younger age group, diagnosed with schizophrenia or mood disorder, and having comorbid substance use disorder, irritable affect, impaired judgment, and absent insight. Most of the events occurred within the first two weeks of admission. About 11% of them had a history of prior absconding from the hospital.

CONCLUSION

Knowledge about the associated sociodemographic and clinical profile would help clinicians and mental health care professionals to prevent absconding. Further risk assessment using a patient's profile would help to reduce absconding events from psychiatric hospitals in the future.

Suicide in Belgian psychiatric inpatients. A matched case-control study in a Belgian teaching hospital

BACKGROUND AND OBJECTIVES

Patients admitted to a psychiatric hospital show an increased risk for suicide but specific risk factors are not well understood.

METHODS

In this case-control study we describe suicides (n = 37) that took place during admission in a Flemish psychiatric teaching hospital between 2007 and 2015 and investigate predictive factors for suicide.

RESULTS

Inpatient suicide is a rare condition (37 patients among 20,442 admission periods between 2007 and 2015). Most inpatients who completed suicide were diagnosed with a mood disorder (68%); 38% committed suicide in the first month of hospitalization and 19% in the first week following admission. The majority of suicides took place just before or during the weekend (57%), with hanging as the prominent method (41%). Multivariate analysis showed that hopelessness was the only significant risk factor for inpatient suicide.

CONCLUSIONS

Inpatient suicide remains a very rare event in inpatient care. Enquiring and managing hopelessness is essential in inpatient treatment of psychiatric patients.

Length of stay in relation to the risk of inpatient and post-discharge suicides: A national health insurance claim data study

BACKGROUND

This study aimed to compare the predictors of suicides among psychiatric inpatients and recently discharged patients and to examine the association between the length of stay and suicides.

METHODS

Data from psychiatric inpatients were extracted from the National Health Insurance databank and merged with information from the Cause of Death data using unique identification numbers. Poisson regression analyses were used to estimate the incidence rate ratio for inpatient and post-discharge suicides, which included the variables of sex, age, psychiatric diagnosis, and number of admissions in the preceding year. The associations between length of stay and inpatient and post-discharge suicide were examined using multivariate Poisson regression analyses that were adjusted for these variables.

RESULTS

A diagnosis of affective disorders and a higher number of previous admissions increased both inpatient and post-discharge suicides. Patients older than 15-24 years had a significantly lower inpatient suicide risk but were more likely to die by suicide post-discharge. The risk of suicide both during the inpatient stay and post-discharge statistically significantly decreased when the length of stay was longer.

LIMITATIONS

As there were variations in societal, environmental, and facility-level factors that might have influenced the association between length of stay and suicide, the generalization of our findings to different settings may be impeded.

CONCLUSIONS

This study provides additional evidence that hospitalization helps to reduce the suicide risk. It suggests that medical professionals should be alert to inpatient suicide and that they should determine the optimal length of stay considering post-discharge suicide.

Suicide in Psychiatric Inpatients- A Case-Control Study

Objective: Psychiatric inpatients constitute a population at considerably increased risk for suicide. Identifying those at imminent risk is still a challenging task for hospital staff. This retrospective case-control study focused on clinical risk factors related to the course of the hospital stay. Method: Inpatient suicide cases were identified by linking the Tyrol Suicide Register with the registers of three psychiatric hospitals in the state. Control subjects were patients who had also been hospitalized in the respective psychiatric unit but had not died by suicide. Matching variables included sex, age, hospital, diagnosis, and admission date. The study period comprised 7 years. Data were analyzed by the appropriate two-sample tests and by logistic regression. Results: A total of 30 inpatient suicide cases and 54 control patients were included. A number of factors differentiated cases from controls; after correction for multiple testing, the following retained significance: history of aborted suicide, history of attempted suicide, history of any suicidal behavior/threats, suicidal ideation continuing during hospitalization, no development of prospective plans, no improvement of mood during the hospital stay, and leaving ward without giving notice. Logistic regression identified the latter three variables and history of attempted suicide as highly significant predictors of inpatient suicide. Conclusions: Preventive measures during hospitalization include thorough assessment of suicidal features, an emphasis on the development of future perspectives, and a review of hospital regulations for patients who want to leave the ward.

Does Compulsory Admission Prevent Inpatient Suicide Among Patients with Schizophrenia? A Nationwide Cohort Study in Taiwan

OBJECTIVE

The aim of this study was to analyze the risk of inpatient suicide in patients with schizophrenia during 2007-2013 and to determine putative risk factors.

METHODS

We conducted a national population-based cohort study of 2,038 psychiatric inpatients in their first compulsory admission, matched with 8,152 controls who were voluntary inpatients. Only patients with schizophrenia were included in the study. We used data derived from the Taiwanese National Health Insurance Database 2005, comprising 1 million beneficiaries randomly selected from the entire population of Taiwan.

RESULTS

During the follow-up period, 23 and 75 inpatient suicides were observed in the compulsory and control groups, respectively. Kaplan-Meier curves showed that the cumulative incidence rate of inpatient suicide was not significantly different between compulsory and voluntary admissions (log-rank test, p = .206).

CONCLUSIONS

Our results suggest that compulsory admission has no protective effects on risk reduction of inpatient suicide for patients with schizophrenia who are compulsorily admitted compared with voluntarily admitted controls. Clinicians should be more alert for the prevention of inpatient suicide among patients with schizophrenia and consider the close monitoring of inpatient suicide risk in the first week of admission.

Association between suicidal ideation and suicide: meta-analyses of odds ratios, sensitivity, specificity and positive predictive value

BACKGROUND

The expression of suicidal ideation is considered to be an important warning sign for suicide. However, the predictive properties of suicidal ideation as a test of later suicide are unclear.AimsTo assess the strength of the association between suicidal ideation and later suicide measured by odds ratio (OR), sensitivity, specificity and positive predictive value (PPV).

METHOD

We located English-language studies indexed in PubMed that reported the expression or non-expression of suicidal ideation among people who later died by suicide or did not. A random effects meta-analysis was used to assess the pooled OR, sensitivity, specificity and PPV of suicidal ideation for later suicide among groups of people from psychiatric and non-psychiatric settings.

RESULTS

There was a moderately strong but highly heterogeneous association between suicidal ideation and later suicide (n = 71, OR = 3.41, 95% CI 2.59-4.49, 95% prediction interval 0.42-28.1, I2 = 89.4, Q-value = 661, d.f.(Q) = 70, P ≤0.001). Studies conducted in primary care and other non-psychiatric settings had similar pooled odds to studies of current and former psychiatric patients (OR = 3.86 v. OR = 3.23, P = 0.7). The pooled sensitivity of suicidal ideation for later suicide was 41% (95% CI 35-48) and the pooled specificity was 86% (95% CI 76-92), with high between-study heterogeneity. Studies of suicidal ideation expressed by current and former psychiatric patients had a significantly higher pooled sensitivity (46% v. 22%) and lower pooled specificity (81% v. 96%) than studies conducted in non-psychiatric settings. The PPV among non-psychiatric cohorts (0.3%, 95% CI 0.1%-0.5%) was significantly lower (Q-value = 35.6, P < 0.001) than among psychiatric samples (3.9%, 95% CI 2.2-6.6).

CONCLUSIONS

Estimates of the extent of the association between suicidal ideation and later suicide are limited by unexplained between-study heterogeneity. The utility of suicidal ideation as a test for later suicide is limited by a modest sensitivity and low PPV.Declaration interestM.M.L. and C.J.R. have provided expert evidence in civil, criminal and coronial matters.

Mental Health Consumers' Motives for Seeking Advocacy Support: A Qualitative Exploration

Advocacy plays a vital role in ensuring that mental health consumers' rights are maintained. However, the primary issues for which consumers seek advocacy support remain unknown. Understanding these issues provides a sound basis from which advocacy organisations may develop a clear service delivery focus. This study addresses the literature gap through presenting a qualitative analysis of 60 records from an advocacy service. Four major themes emerged, across which two key issues were dominant: the sense of fearfulness and disempowerment. These issues accentuate the importance of advocates in enhancing the agency of mental health consumers.

Suicide risk assessment among psychiatric inpatients: a systematic review and meta-analysis of high-risk categories

BACKGROUND

The clinical care of psychiatric patients is often guided by perceptions of suicide risk. The aim of this study was to examine the methods and results of studies reporting high-risk models for inpatient suicide.

METHODS

We conducted a registered meta-analysis according to PRISMA guidelines. We searched for relevant peer-reviewed cohort and controlled studies indexed in Medline, EMBASE and PsychINFO.

RESULTS

The pooled odds ratio (OR) among 18 studies reporting high-risk models for inpatient suicide was 7.1 [95% confidence interval (CI) 4.2-12.2]. Between-study heterogeneity in ORs was very high (range 0-94.8, first quartile 3.4, median 8.8, third quartile 26.1, prediction interval 0.80-63.1, I2 = 88.1%). The meta-analytically derived sensitivity was 53.1% (95% CI 38.2-67.5%, I2 = 95.9%) and specificity was 84.2% (95% CI 71.6-91.9%, I2 = 99.9%) with an associated meta-analytic area under the curve of 0.83. The positive predictive value of risk categorization among six cohort studies was 0.43% (95% CI 0.014-1.3%, I2 = 95.9%). A history of suicidal behavior and depressive symptoms or affective disorder was included in the majority of high-risk models.

CONCLUSIONS

Despite the strength of the pooled association between high-risk categorization and suicide, the very high degree of observed heterogeneity indicates uncertainty about our ability to meaningfully distinguish inpatients according to suicide risk. The limited sensitivity and low positive predictive value of risk categorization suggest that suicide risk models are not a suitable basis for clinical decisions in inpatient settings.

Suicidal ideation and subsequent completed suicide in both psychiatric and non-psychiatric populations: a meta-analysis

AIMS

Several authors claimed that expression of suicidal ideation is one of the most important predictors of completed suicide. However, the strength of the association between suicidal ideation and subsequent completed suicide has not been firmly established in different populations. Furthermore, the absolute suicide risk after expression of suicidal ideation is unknown. In this meta-analysis, we examined whether the expression of suicidal ideation predicted subsequent completed suicide in various populations, including both psychiatric and non-psychiatric populations.

METHODS

A meta-analysis of cohort and case-control studies that assessed suicidal ideation as determinant for completed suicide in adults. Two independent reviewers screened 5726 articles for eligibility and extracted data of the 81 included studies. Pooled risk ratios were estimated in a random effects model stratified for different populations. Meta-regression analysis was used to determine suicide risk during the first year of follow-up.

RESULTS

The risk for completed suicide was clearly higher in people who had expressed suicidal ideation compared with people who had not, with substantial variation between the different populations: risk ratio ranging from 2.35 (95% confidence interval (CI) 1.43-3.87) in affective disorder populations to 8.00 (95% CI 5.46-11.7) in non-psychiatric populations. In contrast, the suicide risk after expression of suicidal ideation in the first year of follow-up was higher in psychiatric patients (risk 1.40%, 95% CI 0.74-2.64) than in non-psychiatric participants (risk 0.23%, 95% CI 0.10-0.54). Past suicide attempt-adjusted risk ratios were not pooled due to large underreporting.

CONCLUSIONS

Assessment of suicidal ideation is of priority in psychiatric patients. Expression of suicidal ideation in psychiatric patients should prompt secondary prevention strategies to reduce their substantial increased risk of suicide.

The investigation of the relationship between probability of suicide and reasons for living in psychiatric inpatients

AIM

This study was carried out to determine the reasons of the suicide probability and reasons for living of the inpatients hospitalized at the psychiatry clinic and to analyze the relationship between them.

MATERIALS AND METHODS

The sample of the study consisted of 192 patients who were hospitalized in psychiatric clinics between February and May 2016 and who agreed to participate in the study. In collecting data, personal information form, suicide probability scale (SPS), reasons for living inventory (RFL), and Beck's depression inventory (BDI) were used. Stepwise regression method was used to determine the factors that predict suicide probability.

RESULTS

In the study, as a result of analyses made, the median score on the SPS was found 76.0, the median score on the RFL was found 137.0, the median score on the BDI of the patients was found 13.5, and it was found that patients with a high probability of suicide had less reasons for living and that their depression levels were very high. As a result of stepwise regression analysis, it was determined that suicidal ideation, reasons for living, maltreatment, education level, age, and income status were the predictors of suicide probability (F = 61.125; P < 0.001).

DISCUSSION

It was found that the patients who hospitalized in the psychiatric clinic have high suicide probability and the reasons of living are strong predictors of suicide probability in accordance with the literature.

Risk Estimates and Risk Factors Related to Psychiatric Inpatient Suicide-An Overview

People with mental illness have an increased risk of suicide. The aim of this paper is to provide an overview of suicide risk estimates among psychiatric inpatients based on the body of evidence found in scientific peer-reviewed literature; primarily focusing on the relative risks, rates, time trends, and socio-demographic and clinical risk factors of suicide in psychiatric inpatients. Psychiatric inpatients have a very high risk of suicide relative to the background population, but it remains challenging for clinicians to identify those patients that are most likely to die from suicide during admission. Most studies are based on low power, thus compromising quality and generalisability. The few studies with sufficient statistical power mainly identified non-modifiable risk predictors such as male gender, diagnosis, or recent deliberate self-harm. Also, the predictive value of these predictors is low. It would be of great benefit if future studies would be based on large samples while focusing on modifiable predictors over the course of an admission, such as hopelessness, depressive symptoms, and family/social situations. This would improve our chances of developing better risk assessment tools.

Self-Injury Implicit Association Test: Comparison of Suicide Attempters and Non-attempters

Given the weaknesses of self-report measures, there has been an increased interest in alternative methods of suicide risk assessment, primarily the implicit measures of suicide risk. This study aimed to determine differences in implicit identification with self-injury and implicit attitude towards self-injury between attempters and non-attempters using the self-injury implicit association test (SI-IAT). The SI-IAT is a computer test designed to measure the implicit associations about self-injury. Participants were 100 forensic and civil inpatients at three psychiatric hospitals. A history of attempted suicide was very common in this sample. All participants completed the SI-IAT. Attempters and non-attempters did not significantly differ with respect to implicit identification with self-injury and implicit attitude towards self-injury. Implications are presented for assessment of suicide risk and future research.

Inpatient Suicide in a Psychiatric Hospital: A Nested Case-control Study

OBJECTIVE

Risk factors for inpatient suicide are different from those in the general population. We examined sociodemographic and clinical variables of patients who committed suicide as an inpatient in a psychiatric hospital in India.

METHODS

Matched retrospective nested case-control design was adopted. Ten patients who died by suicide as inpatients between 2000 and 2013 were included, along with fifty controls, matched with respect to age, sex, diagnosis, and period of admission.

RESULTS

Suicide completers were mostly unskilled in occupation (P = 0.03), had a history of past suicide attempts (P < 0.001), shorter duration of hospital stay (P = 0.001), poorer improvement on psychopathology (P = 0.02), and were having more suicidal ideation (P = 0.02). Significantly more completers were receiving antidepressants (P = 0.04).

CONCLUSION

This study adds to the existing sparse literature on inpatient suicides from Asia. Strength of the study was close matching between case and controls and blindedness. Limitations were retrospective design, and variations in prescription behavior and treatment decisions.

A comparison of suicides in psychiatric in-patients, after discharge and in not recently hospitalized individuals

OBJECTIVE

Time of in-patient treatment and the first weeks after hospital discharge have repeatedly been described as periods of increased suicide risk. This study compared demographic, clinical and suicide related factors between in-patient, post-discharge and not recently hospitalized suicides.

METHODS

Suicide data from the Tyrol Suicide Register were linked with registers of three psychiatric hospitals in the state of Tyrol, Austria. Suicide cases then were categorized as in-patient suicides, post-discharge suicides (suicide within 12weeks after discharge) or never/not within 12weeks before death hospitalized suicides. Data were collected between 2004 and 2011.

RESULTS

Of the total of 711 cases, 30 were in-patient, 89 post-discharge and 592 not recently hospitalized suicides. The three groups differed with regard to male-to-female ratio (lower in both hospitalized groups), marital status, suicide method used (jumping in in-patients, hanging in not recently hospitalized suicides), history of attempted suicide and suicide threats (highest in in-patients) and whether suicides had been in psychiatric or general practitioner treatment shortly before death. In most variables with significant differences there was a gradual increase/decrease with post-discharge suicides taking the middle place between the two other groups.

CONCLUSIONS

The three suicide populations differed in a number of variables. Varying factors appear to influence suicide risk and choice of method differently in in-patient, post-discharge and not hospitalized suicides.

Suicide risk and antipsychotic side effects in schizophrenia: nested case-control study

OBJECTIVE

This study explores suicide risk in schizophrenia in relation to side effects from antipsychotic medication.

METHODS

Among patients with a first clinical discharge diagnosis of schizophrenia or schizoaffective disorder in Stockholm County between 1984 and 2000 (n = 4000), those who died by suicide within 5 years from diagnosis were defined as cases (n = 84; 54% male). For each case, one individually matched control was identified from the same population. Information on antipsychotic side effects, including extrapyramidal symptoms (EPS) and akathisia, as well as prescriptions of anticholinergic medication, was retrieved from clinical records in a blinded fashion. Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) of the association between suicide and side effects as well as anticholinergic medication were estimated using conditional logistic regression.

RESULTS

A lower suicide risk was found in patients with a history of EPS (aOR 0.33, 95% CI 0.12-0.94). There was no statistically significant association between akathisia or anticholinergic medication use and the suicide risk.

CONCLUSIONS

A lower suicide risk identified among patients with EPS could potentially reflect higher antipsychotic adherence, exposure to higher dosage, or polypharmacy among these patients. Copyright © 2016 John Wiley & Sons, Ltd.

Suicidal behavior and mortality in first-episode psychosis

Suicide is a serious public health problem, with more than 800,000 deaths taking place worldwide each year. Mental disorders are associated with increased risk of suicide. In schizophrenia and other psychotic disorders, the lifetime risk of suicide death is estimated to be 5.6%. The risk is particularly high during the first year of the initial contact with mental health services, being almost twice as high as in the later course of the illness. The most consistently reported risk factor for suicide among people with psychotic disorders is a history of attempted suicide and depression. Suicide risk in psychosis in Denmark decreased over time, most likely because of improved quality of inpatient and outpatient services. There is a high proportion of young people with first-episode psychosis who attempted suicide before their first contact with mental health services. This finding suggests that the mortality rates associated with psychotic disorders may be underreported because of suicide deaths taking place before first treatment contact. However, currently, no data exist to confirm or refute this hypothesis. Attempted suicide can be an early warning sign of later psychotic disorder. Data from different studies indicate that the risk of suicide attempt during the first year of treatment is as high as 10%. The most important risk factors for attempted suicide after the first contact are young age, female sex, suicidal plans, and a history of suicide attempt. Early intervention services are helpful in first-episode psychosis, and staff members should, in collaboration with the patients, monitor the risk of suicide and develop and revise crisis plans.

Meta-analysis of suicide rates among psychiatric in-patients

OBJECTIVE

To examine factors associated with the number of psychiatric admissions per in-patient suicide and the suicide rate per 100,000 in-patient years in psychiatric hospitals.

METHOD

Random-effects meta-analysis was used to calculate pooled estimates, and meta-regression was used to examine between-sample heterogeneity.

RESULTS

Forty-four studies published between 1945 and 2013 reported a total of 7552 in-patient suicides. The pooled estimate of the number of admissions per suicide calculated using 39 studies reporting 150 independent samples was 676 (95% CI: 604-755). Recent studies tended to report higher numbers of admissions per suicide than earlier studies. The pooled estimate of suicide rates per 100,000 in-patient years calculated using 27 studies reporting 95 independent samples was 147 (95% CI: 138-156). Rates of suicide per 100,000 in-patient years tended to be higher in more recent samples, in samples from regions with a higher whole of population suicide rate, in samples from settings with a shorter average length of hospital stay and in studies using coronial records to define suicide.

CONCLUSION

Rates of in-patient suicide in psychiatric hospitals vary remarkably and are disturbingly high. Further research might clarify the extent to which patient factors and the characteristics of in-patient facilities contribute to the unacceptable mortality in psychiatric hospitals.

Determinants of completed railway suicides by psychiatric in-patients: case-control study

BACKGROUND

Suicide prediction during psychiatric in-patient treatment remains an unresolved challenge.

AIMS

To identify determinants of railway suicides in individuals receiving in-patient psychiatric treatment.

METHOD

The study population was drawn from patients admitted to six psychiatric hospitals in Germany during a 10-year period (1997-2006). Data from 101 railway suicide cases were compared with a control group of 101 discharged patients matched for age, gender and diagnosis.

RESULTS

Predictors of suicide were change of therapist (OR = 22.86, P = 0.004), suicidal ideation (OR = 7.92, P<0.001), negative or unchanged therapeutic course (OR = 7.73, P<0.001), need of polypharmaceutical treatment (OR = 2.81, P = 0.04) and unemployment (OR = 2.72, P = 0.04). Neither restlessness nor impulsivity predicted in-patient suicide.

CONCLUSIONS

Suicidal ideation, unfavourable clinical course and the use of multiple psychotropic substances (reflecting the severity of illness) were strong determinants of railway suicides. The most salient finding was the vital impact of a change of therapist. These findings deserve integration into the clinical management of patients with serious mental disease.

Nosocomial suicide

OBJECTIVE AND METHOD

To consider the possibility that adverse aspects of psychiatric hospitalisation may precipitate suicide contributing significantly to the increased rate of suicide among inpatients, given little has been published about this.

RESULTS AND CONCLUSIONS

It is likely that psychiatric hospitalisation itself contributes to some inpatient suicides. This has significant implications for the delivery of inpatient psychiatric care.

Mortality among inpatients of a psychiatric hospital: Indian perspective

OBJECTIVE

The objective of this study is to assess mortality and its correlates among psychiatric inpatients of a tertiary care neuropsychiatric hospital. Given the background that such a study has never been undertaken in India, the findings would have a large bearing on policy making from a mental health-care perspective.

MATERIALS AND METHODS

The medical records of those psychiatric inpatients (n = 333) who died during their stay at the National Institute of Mental Health and Neurosciences in past 26 years (January 1983 to December 2008) constituted the study population.

RESULTS

During the 26 years, there were a total of 103,252 psychiatric in-patient admissions, out of which 333 people died during their inpatient stay. Majority (n = 135, 44.6%) of the mortality was seen in the age group of 21-40 years. Most of the subjects were males (n = 202, 67%), married (n = 172, 56.8%) and from urban areas (n = 191, 63%). About, 54% of the subjects had short inpatient stay (<5 days, median for the sample). In 118 (39%) of the subjects, there was a history of physical illness. Leading cause of death were cardiovascular system disorders (n = 132, 43.6%), followed by respiratory system disorders (n = 45, 14.9%), nervous system disorders (n = 30, 9.9%) and infections (n = 31, 10.1%). In 21 (7%), cause of death was suicide.

CONCLUSIONS

Identifying the factors associated with the death of inpatients is of utmost importance in assessing the care in a neuropsychiatric hospital and in formulating better treatment plan and policy in mental health. The discussion focuses on the analysis of different factors associated with inpatient mortality.

Preventing suicide among inpatients

OBJECTIVE

Inpatient suicide comprises a proportionately small but clinically important fraction of suicide. This study is intended as a qualitative analysis of the comprehensive English literature, highlighting what is known and what can be done to prevent inpatient suicide.

METHOD

A systematic search was conducted on the Cochrane Library, PubMed, Embase, Web of Knowledge, and a personal database for articles on cohort series, preferably controlled, of inpatient suicide (not deliberate self-harm or attempted suicide, unless they also dealt specifically with suicide data).

RESULTS

A qualitative discussion is presented, based on the findings of the literature searched.

CONCLUSIONS

The bulk of inpatient suicides actually occur not on the ward but off premises, when the patient was on leave or had absconded. Peaks occur shortly after admission and discharge. It is possible to reduce suicide risk on the ward by having a safe environment, optimizing patient visibility, supervising patients appropriately, careful assessment, awareness of and respect for suicide risk, good teamwork and communication, and adequate clinical treatment.

Inpatient suicide on mental health units in Veterans Affairs (VA) hospitals: avoiding environmental hazards

INTRODUCTION

One thousand five hundred suicides take place on inpatient psychiatry units in the United States each year, over 70% by hanging. Understanding the methods and the environmental components of inpatient suicide may help to reduce its incidence.

METHODS

All Root Cause Analysis reports of suicide or suicide attempts in inpatient mental health units in Veterans Affairs (VA) hospitals between December 1999 and December 2011 were reviewed. We coded the method of suicide, anchor point and lanyard for cases of hanging, and implement for cutting, and brought together all other reports of inpatient hazards from VA staff for review.

RESULTS

There were 243 reports of suicide attempts and completions: 43.6% (106) were hanging, 22.6% (55) were cutting, 15.6% (38) were strangulation, and 7.8% (19) were overdoses. Doors accounted for 52.2% of the anchor points used for the 22 deaths by hanging; sheets or bedding accounted for 58.5% of the lanyards. In addition, 23.1% of patients used razor blades for cutting.

CONCLUSIONS

The most common method of suicide attempts and completions on inpatient mental health units is hanging. It is recommended that common lanyards and anchor points be removed from the environment of care. We provide more information about such hazards and introduce a decision tree to help healthcare providers to determine which hazards to remove.

Suicide in recently admitted psychiatric in-patients: a case-control study

BACKGROUND

Around a quarter of in-patient suicides occur within the first week of admission to psychiatric in-patient care. Little is known on the factors associated with suicide during this critical time. We aimed to identify risk factors for suicide among in-patients within the first week of admission.

METHODS

A national population-based case-control study of 107 current psychiatric in-patients in England who died by suicide within a week of admission, matched on admission date with 107 living controls.

RESULTS

Forty-two (40%) suicide cases died within the first 3 day of admission. A fifth of all suicides were on authorised leave at the time of death, but 34% were off the ward without staff agreement compared to only 1% of controls. Independent risk factors for suicide included previous self-harm, recent adverse life events, and a short (<12 months) duration of illness.

LIMITATIONS

This is a retrospective study, using clinical data mainly collected from case records. Clinicians were not blind to case/control status.

CONCLUSIONS

The first few days of admission should be recognised as the period of highest risk. Careful risk evaluation is needed at this time, particularly in those with recent illness onset or previous suicide attempts. Knowledge of life events experienced before admission should be incorporated into risk assessments. Improvements to the ward environment to lessen the distress of an admission may be an important preventative measure. Protocols may require adapting to improve the safety of those on agreed leave, and prevent absconding through increased vigilance and closer observation of ward exits.

Akathisia and suicidal ideation in first-episode schizophrenia

Patients with first-episode schizophrenia (FES) are known to be notably sensitive for developing extrapyramidal adverse effects, but the relation of akathisia and suicidal ideation has rarely been studied. The current report is an ongoing analysis of an 8-week double-blind randomized controlled multicenter trial in 289 FES, comparing risperidone and haloperidol. Assessments were conducted weekly and included the Hillside Akathisia Scale and 21-item Hamilton Depression Rating Scale ratings. Suicidal ideation was significantly associated with clinician observed akathisia, depressed mood, younger age, and use of propranolol. The allocated treatment, anxiety, and nervousness had no influence. The present findings suggest a promoting effect of akathisia on suicidal ideation can not be ruled out in patients with FES.

The validity and utility of risk assessment for inpatient suicide

OBJECTIVE

It is widely assumed that identifying clinical risk factors can allow us to determine which patients are at high risk of suicide while in hospital, and that identifying those patients can help prevent inpatient suicide. We aimed to examine the validity and utility of categorizing psychiatric patients to be at either high or low risk of committing suicide while in hospital.

METHOD

The assumption that high-risk categorizations are valid was examined by comparing factors included in high-risk models derived from individual studies of inpatient suicide with the results of a meta-analysis of factors associated with inpatient suicide. A valid high-risk model was then applied to a hypothetical clinical setting in order to test the assumption that high-risk categorizations are useful.

RESULTS

The existing models for assessing whether inpatients are at high risk of suicide all include one or more factors that were not found to be associated with inpatient suicide by meta-analysis and were probably chance associations. Depressed mood and a prior history of self-harm are the only well-established independent risk factors for inpatient suicide. Using these risk factors to classify patients as being at high or low risk would prevent few, if any, suicides, and would come at a considerable cost in terms of more restrictive care of many patients and the reduced level of care available to the remaining patients.

CONCLUSIONS

Risk categorization of individual patients has no role to play in preventing the suicide of psychiatric inpatients.

Standardized mortality ratio of inpatient suicide in a general hospital

Inpatient suicide rates are seldom reported using age-standardized methods. This study aimed to estimate the standardized suicide rate in a general hospital. A total of 27 suicidal patients were identified by the adverse event reports during hospitalization from 1995 to 2004. Standardized suicide mortality ratios (SMR) were examined using the Poisson regression model. The SMR of inpatient suicide was 8.25 (95% CI = 5.67-12.06). Hospital suicide rates were considerably higher than the corresponding general population rates for all age groups and were particularly high in age categories of 25-29, 30-34, 40-44, and 55-59 years after controlling for sex and calendar year. Hospitalized patients had an eight times higher risk of suicide mortality than that of the general population. While the elderly are at increased risk for suicide in the general population, young- and middle-aged patients are the age group at risk for suicide mortality during hospitalization.

Systematic review and meta-analysis of the clinical factors associated with the suicide of psychiatric in-patients

OBJECTIVE

To estimate the strength of the associations between the suicide of psychiatric in-patients and demographic, historical, symptomatic, diagnostic and treatment factors.

METHOD

A systematic review and meta-analysis of controlled studies of the suicide of psychiatric in-patients including suicides while on approved or unapproved leave.

RESULTS

Factors that were significantly associated with in-patient suicide included a history of deliberate self-harm, hopelessness, feelings of guilt or inadequacy, depressed mood, suicidal ideas and a family history of suicide. Patients suffering from both schizophrenia and depressed mood appeared to be at particular risk. The association between suicidal ideas and in-patient suicide was weak and did not reach statistical significance after a quantitative correction for publication bias. A high-risk categorization as defined by a combination of retrospectively determined individual risk factors was strongly statistically associated with in-patient suicide (OR=10.9), with a sensitivity of 64% and a specificity of 85%.

CONCLUSION

Despite the apparently strong association between high-risk categorization and subsequent suicide, the low base rate of in-patient suicide means that predictive value of a high-risk categorization is below 2%. The development of safer hospital environments and improved systems of care are more likely to reduce the suicide of psychiatric in-patients than risk assessment.

Case-control study of the relationship of depressive symptoms to suicide in a community-based sample of individuals with schizophrenia in China

BACKGROUND

Suicide is the leading cause of premature death among people with schizophrenia. Most studies on suicide and schizophrenia report an associated depression history, but they are based on clinical samples from mostly western countries.

METHODS

We conducted a secondary analysis of 74 suicides (cases) and 24 accidental deaths (controls) among persons with schizophrenia identified in a national psychological autopsy study in mainland China using the Chinese version of the Structured Clinical Interview for DSM-IV. A 'depression symptom severity score' based on number, severity, and persistence of depressive symptoms 2 weeks before death was derived from psychiatric interviews with 2 informants; determination of a 'dysfunction due to depressive symptoms score' was based on informants' reports about effects of depressive symptoms on decedents' functioning in the month before death. In addition, the mean number of negative life events was determined along with the effect of the events on the decedent. Comparison of the measures made for cases and controls were made by univariate analysis followed by adjustments using the False Discovery Rate.

RESULTS

Compared to persons with schizophrenia who died by accident, those who died by suicide were more likely to have a recent DSM IV diagnosis of major depression, the symptom of depressed mood, thoughts of death and a prior suicide attempt. In addition, those who died by suicide were more likely to have a higher overall depression severity score and greater dysfunction due to depressive symptoms.

DISCUSSION

This community-based study of individuals with DSM-IV schizophrenia who died by suicide in a non-western culture extends findings from clinical studies in western cultures providing data on the importance of depressive symptoms as risk factors for suicide in schizophrenia in a low income rural setting. These findings underline the importance of routine screening for depressive symptoms among patients with schizophrenia.

Rural-urban differences in suicide rates for current patients of a public mental health service in Australia

Rural versus urban rates of suicide in current patients of a large area mental health service in Australia were compared. Suicide deaths were identified from compulsory root cause analyses of deaths, 2003-2007. Age-standardized rates of suicide were calculated for rural versus urban mental health service and compared using variance of age-standardized rates with 95% confidence intervals. There were 44 suicides and the majority (62%) were rural. Only urban patients used jumping from heights as a method of suicide (4/17; p = 0.02). Rural patients had 2.7 times higher rates of suicide, similar to findings for rural versus urban community suicides and may reflect the underlying community rates, differences in mental health service delivery, or socioeconomic disadvantage.

A checklist to identify inpatient suicide hazards in veterans affairs hospitals

BACKGROUND

Approximately 1,500 suicides take place in inpatient hospital units in the United States each year. This study, the first of its kind, examines the implementation and effectiveness of using a standardized checklist for mental health units to improve patient safety in a large health care system.

METHODS

In 2006 a Department of Veterans Affairs (VA) committee was charged with developing a checklist to explicitly identify environmental hazards on acute mental health units treating suicidal patients. The committee developed both general guidelines to be applied to all areas of the psychiatric unit and detailed guidelines for specific rooms, such as bathrooms, bedrooms, and seclusion rooms.

RESULTS

Some 113 VA facilities used the Mental Health Environment of Care Checklist to evaluate their mental health units, identifying and rating 7,642 hazards. At the end of the first year of the project, because of the checklist, 5,834 (76.3%) of these hazards had been abated by facilities; approximately 2% were identified as critical hazards, and another 27% were rated as serious. The most common hazard was anchor points for hanging, followed by material that could be used as a weapon against staff or other patients and problems keeping patients in the secured unit environment. Anchor points had the greatest risk-level classification, followed by suffocation risk and poison risk. High-risk locations included bedrooms and bathrooms.

DISCUSSION

Anchor points represented almost 44% of the total number of identified hazards, and materials that could be used as weapons comprised nearly 14% of the total. It is critical to review the mental health environment of care with an eye for these potential weapons. The checklist and resulting mitigations of hazards represent steps toward the overall goal of preventing inpatient suicides.

Suicide inside: a systematic review of inpatient suicides

The literature on inpatient suicides was systematically reviewed. English, German, and Dutch articles were identified by means of the electronic databases PsycInfo, Cochrane, Medline, EMBASE psychiatry, CINAHL, and British Nursing Index. In total, 98 articles covering almost 15,000 suicides were reviewed and analyzed. Rates and demographic features connected to suicides varied substantially between articles, suggesting distinct subgroups of patients committing suicide (e.g., depressed vs. schizophrenic patients) with their own suicide determinants and patterns. Early in the admission is clearly a high-risk period for suicide, but risk declines more slowly for patients with schizophrenia. Suicide rates were found to be associated with admission numbers, and as expected, previous suicidal behavior was found to be a robust predictor of future suicide. The methods used for suicide are linked to availability of means. Timing and location of suicides seem to be associated with absence of support, supervision, and the presence of family conflict. Although there is a strong notion that suicides cluster in time, clear statistical evidence for this is lacking. For prevention of suicides, staff need to engage with patients' family problems, and reduce absconding without locking the door. Future research should take into account the heterogeneous subgroups of patients who commit suicide, with case-control studies addressing these separately.

Suicide amongst psychiatric in-patients who abscond from the ward: a national clinical survey

BACKGROUND

Suicide prevention by mental health services requires an awareness of the antecedents of suicide amongst high risk groups such as psychiatric in-patients. The goal of this study was to describe the social and clinical characteristics of people who had absconded from an in-patient psychiatric ward prior to suicide, including aspects of the clinical care they received.

METHODS

We carried out a national clinical survey based on a 10-year (1997-2006) sample of people in England and Wales who had died by suicide. Detailed data were collected on those who had been in contact with mental health services in the year before death.

RESULTS

There were 1,851 cases of suicide by current psychiatric in-patients, 14% of all patient suicides. 1,292 (70%) occurred off the ward. Four hundred and sixty-nine of these patients died after absconding from the ward, representing 25% of all in-patient suicides and 38% of those that occurred off the ward. Absconding suicides were characterised by being young, unemployed and homeless compared to those who were off the ward with staff agreement. Schizophrenia was the most common diagnosis, and rates of previous violence and substance misuse were high. Absconders were proportionally more likely than in-patients on agreed leave to have been legally detained for treatment, non-compliant with medication, and to have died in the first week of admission. Whilst absconding patients were significantly more likely to have been under a high level of observation, clinicians reported more problems in observation due to either the ward design or other patients on the ward.

CONCLUSION

Measures that may prevent absconding and subsequent suicide amongst in-patients might include tighter control of ward exits, and more intensive observation of patients, particularly in the early days of admission. Improving the ward environment to provide a supportive and less intimidating experience may contribute to reduced risk.

Suicide rate in schizophrenia in the Northern Finland 1966 Birth Cohort

BACKGROUND

Suicide rate among schizophrenia patients may vary for several reasons, one of the most important being the time point of the suicide during the illness process. However, prospective studies on suicide risk in population-based cohort of individuals with new-onset schizophrenia have been lacking.

METHOD

The data were collected for 10,934 individuals alive in Finland at the age of 16 from the genetically homogenous, population-based Northern Finland 1966 Birth Cohort ascertained already during mid-pregnancy. The Finnish Hospital Discharge Register was used until the end of 1997 (age 31) to identify cases with mental disorder. Case records were scrutinized and diagnoses were re-checked for DSM-III-R criteria. One hundred subjects met the DSM-III-R criteria for schizophrenia. Deaths by the end of year 2005 (age 39) were ascertained from death certificates.

RESULTS

Suicides (n = 7) accounted for 50% of all the deaths at age from 16 to 39. Seven (7.0%) subjects with schizophrenia had committed suicide; suicide rate being 2.9% (1/35) for women and 9.2% (6/65) for men. Furthermore, 71% of suicides in schizophrenia occurred during the first 3 years after onset of illness.

CONCLUSION

The suicide rate for patients with new-onset schizophrenia followed until the age of 39 was high and accounted for half of the deaths. Great majority of the suicides took place during the first years of the illness.

In-patient suicide--a 13-year assessment

OBJECTIVE

To describe the suicide rates of psychiatric in-patients in the canton of Zurich for the period 1992-2004, and to determine putative risk factors.

METHOD

The data were derived from the psychiatric case register of the canton Zurich. The analyses were based on person-years calculations and standardised mortality ratios. Additional information was assessed via case records.

RESULTS

During the 13-year period the standardised mortality ratio was 48.9. The risk of suicide was particularly high in patients with personality and affective disorders. Most suicides occurred during regular leave periods, despite the fact that clinical assessment had indicated there was no suicide risk for the patient.

CONCLUSION

The suicide risk of in-patients is distinctly higher than in the general population. A better assessment of suicide risk before regular leave periods could lead to a decrease of suicides in in-patient settings, as well as a more rigorous treatment of borderline cases, and of affective and psychotic symptoms.

Inpatient suicide in a general hospital

OBJECTIVES

This study aimed to compare the characteristics of psychiatric and nonpsychiatric suicidal inpatients in one general hospital and examine the predictors of completed suicide in the patients with suicidal acts during hospitalization.

METHODS

One hundred ten study subjects were identified by the adverse event reports of suicidal acts during hospitalization from 1995 to 2004. Demographic data and clinical information were collected by chart reviews.

RESULTS

Psychiatric inpatients with suicidal acts were mainly younger females with psychiatric diagnoses and previous suicide attempts. Nonpsychiatric suicidal inpatients had less suicide communication, performed suicidal acts more rapidly after admission and used more violent suicidal methods than the psychiatric inpatients did. Suicidal acts performed outside the hospital, use of violent suicidal methods and male gender increased the risk of suicide mortality in our suicidal inpatients.

CONCLUSION

This study suggests that suicide prevention efforts need to be tailored in psychiatric and nonpsychiatric wards according to differing patient risk characteristics in these patient cohorts.

Suicide in the medical setting

BACKGROUND

Little is known about suicide in the hospital setting. Although suicide is a major public health concern, the literature on suicide in the medical setting is limited, and accurate data on hospital-based suicides are unavailable. Consequently, the prevalence, demographic characteristics, and risk factors for suicide in this population are unknown. The literature on completed suicides in medical or surgical wards of a general hospital was summarized to generate hypotheses for further investigation regarding in-hospital suicides.

METHODS

MEDLINE, PsycINFO, IndexCat, and Scopus were queried for English-language articles on inpatient suicides in a general hospital. These data were compared with reports of suicide by psychiatric inpatients and the annual suicide statistics from the U.S. general population.

RESULTS

Twelve articles detailing 335 suicides in the medical setting were included. Published data on hospital-based suicides are limited by selection bias, incomplete reporting, and a small number of completed suicides. Consequently, no significant setting-specific findings emerge from the existing literature. Reported cases suggest that inpatients who commit suicide in the medical setting may have a different demographic profile and employ different methods of suicide in comparison with individuals who commit suicide in psychiatric settings or the general population.

DISCUSSION

Given the absence of systematic data collection and the highly variable nature of reported suicides, it could not be determined if clinically relevant distinctions exist between suicides in different health care settings. Prospective and more detailed data collection are needed because a more complete characterization of suicide in medical inpatients may be useful in both prevention approaches and institutional policies with respect to hospital-based suicides.

Inpatient suicide and suicide attempts in Veterans Affairs hospitals

BACKGROUND

Suicide is the eleventh leading cause of death in the United States. Approximately 1,500 suicides occur in inpatient hospital units in the United States each year. In an attempt to determine the methods and environmental factors involved in inpatient suicide and suicide attempts in Department of Veterans Affairs (VA) hospitals, all root cause analysis (RCA) reports of inpatient suicides and suicide attempts submitted to the VA National Center for Patient Safety (NCPS) before June 2006 were reviewed.

METHODS

VA medical centers are required to conduct RCAs on all inpatient suicides and report all suicides and serious suicide attempts to the NCPS. All reports of inpatient suicide and suicide attempts submitted between December 1999 and June 2006 were reviewed, including methods and environmental factors involved in the events.

RESULTS

A total of 185 inpatient suicide and suicide attempts were reported; 42 were completed suicides and 143 were suicide attempts. Approximately 52% of the total number of events occurred while the patient was on an inpatient psychiatry unit. Three methods of self harm--intentional drug overdose, cutting with a sharp object, and hanging--accounted for 71% of the total number of events. Doors and wardrobe cabinets accounted for 41% of the anchor points when hanging was the method of self-harm. For suicide attempts involving cutting behaviors, razor blades accounted for 37% of the total number of events; 57% of jumping-related events occurred from balconies and walkways.

CONCLUSIONS

Careful review of RCA reports of inpatient suicide has resulted in focused interventions to improve patient care and patient safety in VA medical centers, including a comprehensive environment-of-care checklist for reviewing inpatient psychiatry units.
