Suicide Prevention Strategies for General Hospital and Psychiatric Inpatients: A Narrative Review

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.

Self-harming behaviors and forensic system-related factors: an analysis of the Ontario review board database

BACKGROUND

In Canada, ensuring public safety, and the safety and well-being of accused individuals under the jurisdiction of the provincial review board are very important. While previous studies have reported a significant risk of self-harming behaviors (non-suicidal self-injury and suicide attempt) in forensic psychiatric settings, no large population study has assessed any relationship between forensic system-related factors and self-harming behaviors. A better understanding of these factors can help clinicians implement protective measures to mitigate self-harming behaviors or actions.

METHODS

Using the Ontario Review Board (ORB) database covering 2014-2015 period (n = 1211, mean age = 42.5 ± 13.37 years, males = 86.1%), we analyzed the prevalence and factors associated with self-harming behaviors, emphasizing the characterization of the forensic system-related factors (ORB status, legal status, type of offense, previous criminal history, and victim relationship). The relationships between the forensic system-related factors and self-harming behaviors were explored using five separate logistic regression models, controlling for clinical and sociodemographic characteristics.

RESULTS

Approximately 4% of the individuals in the forensic system over the study period engaged in self-harming behaviors Among the studied patients, individuals determined to be unfit to stand trial and inpatients were significantly more likely to have self-harming behaviors. There was no significant relationship between the type of offence, victim relationship, and previous criminal history with self-harming behavior.

CONCLUSION

Forensic psychiatry inpatients should have close observation, screening, monitoring, and individual tailored management strategies for self-harming behaviors. The findings of this study indicate that forensic system-related factors, especially those that pertain to the status of individuals in the forensic system (i.e., unfit to stand trial and being an inpatient) are more responsible for self-harming behaviors among forensic patients in Ontario.

Factors Affecting Inpatients' Mortality through Intentional Self-Harm at In-Hospitals in South Korea

This study aimed to identify the patient characteristics, comorbidities, risk factors, and means of the self-harm of patients who attempt self-harm in and outside of a hospital, and to determine the characteristics of death by suicide among survival and death patient groups in South Korea. This study used data from the Korean National Hospital Discharge In-depth Injury Survey conducted from 2007 to 2019. In total, 7192 outpatient participants and 43 inpatient participants performed self-harm. Frequency analysis, chi-square tests, Fisher's exact test, and logistic regression analysis were performed using STATA, version 15.0 (StataCorp), and statistical significance was set at 5%. Thirty-one inpatients who performed self-harm survived, and 12 died. Among male inpatients, the older they were, the higher the rates of self-harm and mortality rates due to falls and poisoning if they had comorbidities and financial problems. In addition, the rate of self-harm attempts within a short period after hospitalization was high. Our evidence of the characteristics of patients who performed self-harm in the hospital and the influencing factors of self-harm can be used as primary data for predicting patients at a high risk of self-harm and for creating preventative policies to reduce the risk of self-harm among inpatients in South Korea.

Exploring risk factors for re-hospitalization in a psychiatric inpatient setting: a retrospective naturalistic study

BACKGROUND

The reduction of multiple psychiatric hospitalizations is an important clinical challenge in mental health care. In fact, psychiatric re-hospitalization negatively affects the quality of life and the life expectancy of patients with psychiatric disorders. For these reasons, identifying predictors of re-hospitalization is important for better managing psychiatric patients. The first purpose of the present study was to examine the readmission rate in a large sample of inpatients with a psychiatric disorder. Second, we investigated the role of several demographical and clinical features impacting re-hospitalization.  METHOD: This retrospective study enrolled 1001 adult inpatients (510 men and 491 women) consecutively admitted to the University Psychiatric Clinic, Sant'Andrea Hospital, Sapienza University of Rome between January 2018 and January 2022. To identify risk factors for psychiatric re-hospitalization, we divided the sample into 3 subgroups: the Zero-Re group which had no readmission after the index hospitalization, the One-Re group with patients re-admitted only once, and the Two-Re with at least two re-admissions.  RESULTS: The groups differed according to previous hospitalizations, a history of suicide attempts, age at onset, and length of stay. Furthermore, the results of the regression model demonstrated that the Two-Re group was more likely to have a history of suicide attempts and previous hospitalizations.

DISCUSSION

These results indicate the importance of assessing risk factors in psychiatric hospitalized patients and implementing ad hoc prevention strategies for reducing subsequent re-hospitalizations.

Developing inpatient suicide prevention strategies in medical settings: Integrating literature review with expert testimony

OBJECTIVE

According to some recent evidence, suicide rate is higher in inpatients than in the general population around the world. However, suicide prevention strategies (SPS) are poorly focused and understood in medical settings. This study aimed to develop effective SPS and interventions in medical settings of Iran and provide evaluation checklists/procedures for them.

METHODS

The study was performed in two steps, including literature review and expert opinions panel. In the first stage, we conducted a comprehensive literature review to find relevant suicide prevention programs, strategies, interventions, or any efforts to prevent suicide in the medical settings. In the second stage, an expert panel was arranged for developing effective and feasible SPS in medical settings. Data were analyzed through content analysis approach.

RESULTS

Overall, 11 records were included in the literature review. SPS varied from staff training, safety plan and quality improvements, and prevention programs to therapy methods. Finally, in the second stage, the following seven major SPS were recommended by the expert panel: 1) Integration and application of obtained suicidal behavior data through evaluating medical records, 2) Screening and suicide risk assessment, 3) Staff training, 4) Quality improvement, 5) Follow-up of inpatients with high-risk behaviors, 6) Reducing stigma and improving public awareness, and 7) Follow-up of discharged high-risk inpatients. Also, 23 interventions within the strategies were presented.

CONCLUSION

Given that SPS are poorly focused in medical settings, the practical framework that emerged in this study could be used to develop or advance SPS in various medical settings.

Safe environment management in acute psychiatric wards in the Czech Republic, foundation for recommendations for preventive practice

OBJECTIVES

Suicides of hospitalized patients present rare but very serious adverse events in healthcare settings. The aim of this article is to describe and analyse the facilities and material equipment of acute psychiatric settings in the Czech Republic and contrast these with recommendations for effective prevention of suicidal behaviour. Since there are currently no universally accepted protocols for risk assessment and prevention of suicides in hospital settings in the Czech Republic, these recommendations draw on international guidelines. Based on the outcomes of our study we provide recommendations for risk management and effective prevention of suicidal behaviour of patients hospitalized in acute care settings.

METHODS

In order to describe and analyse the environment of acute psychiatric wards in the Czech Republic we have developed a questionnaire based on international recommendations for risk management and prevention of suicidal behaviour. We also collected data on the prevalence of attempted and completed suicides and their respective methods in these hospitals.

RESULTS

We have established that acute psychiatric wards in the Czech Republic operate within insufficient safety regimes, especially with respect to the prevention of suicide by hanging and the accessibility of objects for cutting. Our findings demonstrate that only 75% of the wards are equipped with safety glass, and only 50% of the wards with safety mirrors. Only just over 40% of hospitals have safety door handles and shower heads.

CONCLUSION

While it is impossible to entirely eliminate the risk of suicidal behaviour it is possible to manage it. The risk reduction is attainable by providing a safe-proofed environment and minimizing opportunities of suicide attempts by hanging and cutting. In order to effectively prevent suicides, it is essential to increase the awareness of the possibilities of safe proofing of the environment as well as standardization of risk assessment of potential suicidal behaviour of patients.

COVID-19 and suicides in India: A pilot study of reports in the media and scientific literature

BACKGROUND

Our objective was to analyze reports of COVID-19 related suicides (CRS) to identify associated factors with a broader goal to inform management and prevention strategies.

METHODS

We searched scientific literature, government websites and online newspaper reports in English and nine regional languages to identify relevant CRS reports.

RESULTS

A total of 151 CRS reports were retrieved. CRS was more frequently reported among males (80.8%), those whose COVID status was unknown (48.0%), and those in quarantine/isolation (49.0%).

CONCLUSION

The above findings may assist identification of at-risk individuals for COVID-19 related suicidal behavior.

Retrospective analysis of reported suicide deaths and attempts on veterans health administration campuses and inpatient units

INTRODUCTION

Suicide is the 10th leading cause of death in the USA. Inpatient suicide is the fourth most common sentinel event reported to the Joint Commission. This study reviewed root cause analysis (RCA) reports of suicide events by hospital unit to provide suicide prevention recommendations for each area.

METHODS

This is a retrospective analysis of reported suicide deaths and attempts in the US Veterans Health Administration (VHA) hospitals. We searched the VHA National Center for Patient Safety RCA database for suicide deaths and attempts on inpatient units, outpatient clinics and hospital grounds, between December 1999 and December 2018.

RESULTS

We found 847 RCA reports of suicide attempts (n=758) and deaths (n=89) in VHA hospitals, hanging accounted for 71% of deaths on mental health units and 50% of deaths on medical units. Overdose accounted for 55% of deaths and 68% of attempts in residential units and the only method resulting in death in emergency departments. In VHA community living centres, hanging, overdose and asphyxiation accounted for 64% of deaths. Gunshot accounted for 59% of deaths on hospital grounds and 100% of deaths in clinic areas. All inpatient locations cited issues in assessment and treatment of suicidal patients and environmental risk evaluation.

CONCLUSIONS

Inpatient mental health and medical units should remove anchor points for hanging where possible. On residential units and emergency departments, assessing suicide risk, conducting thorough contraband searches and maintaining observation of suicidal patients is critical. In community living centres, suicidal patients should be under supervision in an environment free of anchor points, medications and means of asphyxiation. Suicide prevention on hospital grounds and outpatient clinics can be achieved through the control of firearms.
