Profile of Hospital Admissions due to Self-Inflicted Harm in Los Angeles County from 2001 to 2010

Hospital presenting suicidal ideation: A systematic review

BACKGROUND

Research indicates that the emergency department is the primary setting for people to present with suicidal ideation. Attempting to provide interventions for this population depends greatly on understanding their needs and life circumstances at the time of presentation to services, therefore enabling more appropriate treatment pathways and services to be provided.

AIM

This review aims to collate, evaluate and synthesize the empirical research focused on the population of people presenting to hospital settings with suicidal ideation.

METHOD

A systematic literature search was performed. Articles that met a specified set of inclusion criteria including participants being over 18, not being admitted to hospital and presenting to an emergency department setting underwent a quality assessment and data analysis. The quality assessment used was the EPHPP Quality Assessment Tool for Quantitative Studies (Thomas et al., 2004).

RESULTS

Twenty-seven articles were included in the review. Studies were quantitative and of reasonable methodological quality (Thomas et al., 2004). The literature was characterized by demographic information, mental health factors associated with the presentation to hospital and treatment pathways or outcomes reported. The reviewed research showed that people presenting to emergency departments with suicidal ideation were varying in age, gender, ethnic background and socio-economic status (SES). Large proportions of studies reported psychosocial factors alongside interpersonal struggles as the main presenting reason. The review highlights large variability across these factors. Mental health diagnosis was common, previous suicide attempt was a risk factor, and treatment pathways were unclear. The review identifies the outstanding gaps and weaknesses in this literature as well as areas in need of future research.

CONCLUSIONS

In conclusion, the review highlights the prevalence of people reporting interpersonal factors as the reason for suicidal ideation and not mental health disorders or diagnosis. Despite this, no mention of trauma or life stories was made in any study assessing this population. Despite a large variation across studies making synthesis difficult, data proves clinically relevant and informative for future practice and guidance on areas needing further research.

Epidemiologic characteristics of hospitalised patients after suicidal acts from 2005 to 2016 in Korea: Analysis of the Korean National Hospital Discharge Survey

BACKGROUND

Suicide is a major cause of death in many countries, and previous suicidal attempt is known to be the predictor of future suicide. Korea is considered one of the countries with the highest suicide rate among the Organisation for Economic Co-operation and Development (OECD) members for over a decade. We aimed to investigate the epidemiologic characteristics of hospitalised patients after suicidal acts in Korea.

METHODS

Data from the Korean National Hospital Discharge In-depth Injury Survey were analysed, and patients older than 9 years admitted to nationwide hospitals after suicidal acts from 2005 to 2016 were included. Their epidemiologic characteristics were explored, and we divided them into groups according to suicidal means (injury vs. poisoning) and treatment outcome (good vs. poor). The association of each characteristic with injury as suicidal means and with poor treatment outcome were explored.

RESULTS

The sample included 7609 patients (corresponding to 227,571 in national population). More patients were female than male, and most were in their 40s in both sexes. Hospitalisation rate peaked in patients older than 80 years for both sexes. Male and young patients aged 10-19 years and capital residents showed relatively higher odds of choosing injury as suicidal means. Males and patients aged 40-64 and ≥65 years showed relatively higher odds of poor treatment outcome.

LIMITATIONS

Some suicide attempters were excluded from the survey such as those who did not visit a hospital after the suicide attempt.

CONCLUSIONS

This epidemiologic feature of suicide attempters might serve as baseline data for preventive policies regarding suicide.

Gender Differences in Suicide and Self-Directed Violence Risk Among Veterans With Post-traumatic Stress and Substance Use Disorders

BACKGROUND

Veterans have a high prevalence of both post-traumatic stress disorder (PTSD) and substance use disorders (SUDs), which are related to suicide risk. Exploring gender-related differences in suicidal behavior risk among this subgroup of veterans is important to improve prevention and treatment strategies. To date, few studies have explored these differences.

METHODS

The sample included 352,476 men and women veterans from the Women Veterans Cohort Study with a diagnosis of PTSD. First, we conducted analyses to assess gender-related differences in sociodemographic and clinical variables at baseline, as well as by suicidal behavior. Then, we conducted a series of Cox proportional hazards regression models to estimate the hazard ratios of engaging in self-directed violence (SDV) and dying by suicide by SUD status and gender, controlling for potential confounders.

RESULTS

Adjusted analyses showed that, among veterans with PTSD, the presence of a SUD significantly increased the risk of SDV and death by suicide. Women with PTSD had a decreased risk of dying by suicide compared with men. No gender-related difference was observed for SDV. SUD increased the risk of SDV behavior in both women and men but increased the risk of dying by suicide only among men.

CONCLUSIONS

Our findings revealed gender-related differences in SDV and suicide among veterans with a PTSD diagnosis with or without a SUD. Our study, along with the increasing numbers of women serving in the military, stresses the need to conduct gender-based analyses to help improve prevention and treatment strategies.

Socio-Demographic and Mental Health Profile of Admitted Cases of Self-Inflicted Harm in the US Population

Self-inflicted harm (SIH) has a substantial lifetime prevalence, it is associated with tremendous costs, and its rate is increasing on a national scale. To examine the characteristics of those admitted for SIH in the US and to investigate the factors that potentially modify the methods used for SIH. This was a retrospective analysis of admitted cases of SIH including suicide attempts between 2007 and 2012 using the National Trauma Data Bank. We included a total of 204,633 cases admitted for SIH. Our participants were 75.1% males. Those aged 15-24 (21%), 25-34 (22%), 35-44 (19%), 45-54 (19%), and 55-64 (10%) years comprised the largest age groups among our cases-70.8%, 11.5%, 11.1%, and 6.6% were, respectively, Caucasians, Hispanics, Blacks, and Asian/Others. Analyses of the SIH methods revealed that Blacks were less likely to self-poison [Odds Ratio (OR): 0.78] compared to Whites, whereas individuals with psychiatric disorders or substance abuse carried 2.5 and 2.0-fold higher risk, respectively. Blacks were also less likely to use anoxic methods (OR: 0.69), whereas patients with psychiatric disorders or substance abuse carried 1.5-fold higher risk. Being Black, Hispanic, and Asian (OR: 0.58, 0.55, and 0.55, respectively) as well as having psychiatric disorders (OR: 0.80) were associated with lower risks of using firearms, whereas its risk was increased with increasing age. Blacks (OR: 0.77) were less likely to cut or pierce in contrast to Hispanics (OR: 1.4), Asians/Others (OR: 1.29), and those with psychiatric disorders (2.5-fold higher risk) or drug abuse (2-fold higher risk). Blacks (OR: 1.11), Hispanics (OR: 1.13), and Asians/Others (OR: 1.57) were more likely to jump from high places, whereas those with substance abuse were less likely (OR: 0.77). Among patients admitted for SIH, males, those aged 15-64 years, and Whites comprised the largest sex, age, and racial/ethnic groups, respectively. We also found that several factors including race/ethnicity, gender, age, and having concurrent psychiatric or drug abuse disorders can potentially influence the methods used for SIH.
