Deliberate self-harm in older adults: A national analysis of US emergency department visits and follow-up care

National Trends in Emergency Department Visits for Suicide Attempts and Intentional Self-Harm

OBJECTIVE

This study estimated national annual trends and characteristics of emergency department visits for suicide attempts and intentional self-harm in the United States from 2011 to 2020.

METHODS

Data were from the National Hospital Ambulatory Medical Care Survey, an annual cross-sectional national sample survey of emergency departments. Visits for suicide attempts and intentional self-harm were identified using discharge diagnosis codes (ICD-9-CM for 2011-2015; ICD-10-CM for 2016-2020) or reason-for-visit codes. The annual proportion of emergency department visits for suicide attempts and intentional self-harm was estimated.

RESULTS

The weighted number of emergency department visits for suicide attempts and intentional self-harm increased from 1.43 million, or 0.6% of total emergency department visits, in 2011-2012 to 5.37 million, or 2.1% of total emergency department visits in 2019-2020 (average annual percent change, 19.5%, 95% CI=16.9, 22.2). Visits per capita increased from 261 to 871 visits per 100,000 persons (average annual percent change, 18.8%, 95% CI=17.6, 20.0). The increase in visits was widely distributed across sociodemographic groups. While suicide attempt and intentional self-harm visits were most common among adolescents, adults age 65 or older demonstrated the largest increase (average annual percent change, 30.2%, 95% CI=28.5, 32.0). Drug-related diagnoses were the most common co-occurring diagnosis among suicide attempt and intentional self-harm visits. Despite the rise in emergency department visits for suicide attempts and intentional self-harm, less than 16% included an evaluation by a mental health professional.

CONCLUSIONS

A significant national increase in emergency department visits for suicide attempts and intentional self-harm occurred from 2011 to 2020, as a proportion of total emergency department visits and as visits per capita. These trends underscore an urgent need to improve the continuum of mental health care for individuals with suicidal symptoms.

Exploring community mental health service use following hospital-treated intentional self-harm among older Australians: a survival analysis

OBJECTIVES

This study aimed to examine the impact of community mental health (CMH) care following index hospital-treated intentional self-harm (ISH) on all-cause mortality. A secondary aim was to describe patterns of CMH care surrounding index hospital-treated ISH.

DESIGN

A longitudinal whole-of-population record linkage study was conducted (2014-2019), with index ISH hospitalization (Emergency Department and/or hospital admissions) linked to all available hospital, deaths/cause of death, and CMH data.

SETTING

Australia's most populous state, New South Wales (NSW) comprised approximately 7.7 million people during the study period. CMH services are provided statewide, to assess and treat non-admitted patients, including post-discharge review.

PARTICIPANTS

Individuals with an index hospital presentation in NSW of ISH during the study period, aged 45 years or older.

INTERVENTION

CMH care within 14 days from index, versus not.

MEASUREMENTS

Cox-proportionate hazards regression analysis evaluated all-cause mortality risk, adjusted for relevant covariates.

RESULTS

Totally, 24,544 persons aged 45 years or older experienced a nonfatal hospital-treated ISH diagnosis between 2014 and 2019. CMH care was received by 56% within 14 days from index. Survival analysis demonstrated this was associated with 34% lower risk of death, adjusted for age, sex, marital status, index diagnosis, and 14-day hospital readmission (HR 0.66, 95% CI 0.58, 0.74, p < 0.001). Older males and chronic injury conveyed significantly greater risk of death overall.

CONCLUSIONS

CMH care within 14 days of index presentation for self-harm may reduce the risk of all-cause mortality. Greater effort is needed to engage older males presenting for self-harm in ongoing community mental health care.

Factors Influencing Emergency Department Staff Decision-Making for People Attending in Suicidal Crisis: A Systematic Review

BACKGROUND

Emergency department (ED) staff are often the first point of contact for individuals in suicidal crisis. Despite this, there is no published research systematically examining the factors influencing decision-making for this patient group.

METHODS

MedLine, CINAHL, PsycINFO, Web of Science and Cochrane Library databases were searched for three key concepts: (1) suicide, (2) accident and emergency department and (3) decision-making. Three reviewers screened titles, abstracts and full papers independently against the eligibility criteria. Data synthesis was achieved by extracting and analyzing study characteristics and findings. The Mixed Methods Appraisal Tool (MMAT) was used to assess the quality of included studies.

RESULTS

Seventeen studies met the eligibility criteria and were included in this systematic review. Studies were published from 2004 to 2020 and were of good methodological quality. A number of patient (method of self-harm, age, gender), contextual (availability of services and staff) and staff-related factors (attitudes, training, knowledge) were reported to influence decision-making for patients in suicidal crisis presenting to EDs.

CONCLUSION

Decision-making in the ED is complex and is influenced by patient, contextual and staff-related factors. These decisions can have an impact on the future care and clinical pathways of patients in suicidal crisis. Additional training is needed for ED staff specifically related to suicide prevention.

Death by suicide among aged care recipients in Australia 2008-2017

OBJECTIVE

To characterize the features of aged care users who died by suicide and examine the use of mental health services and psychopharmacotherapy in the year before death.

DESIGN

Population-based, retrospective exploratory study.

SETTING AND PARTICIPANTS

Individuals who died while accessing or waiting for permanent residential aged care (PRAC) or home care packages in Australia between 2008 and 2017.

MEASUREMENTS

Linked datasets describing aged care use, date and cause of death, health care use, medication use, and state-based hospital data collections.

RESULTS

Of 532,507 people who died, 354 (0.07%) died by suicide, including 81 receiving a home care package (0.17% of all home care package deaths), 129 in PRAC (0.03% of all deaths in PRAC), and 144 approved for but awaiting care (0.23% of all deaths while awaiting care). Factors associated with death by suicide compared to death by another cause were male sex, having a mental health condition, not having dementia, less frailty, and a hospitalization for self-injury in the year before death. Among those who were awaiting care, being born outside Australia, living alone, and not having a carer were associated with death by suicide. Those who died by suicide more often accessed Government-subsidized mental health services in the year before their death than those who died by another cause.

CONCLUSIONS

Older men, those with diagnosed mental health conditions, those living alone and without an informal carer, and those hospitalized for self-injury are key targets for suicide prevention efforts.

Secondary mental health service utilisation following emergency department contact for suicidal behaviour: A systematic review

OBJECTIVE

Engagement with secondary mental health services after an emergency department presentation with suicidal behaviours may be an important strategy for reducing the risk of repeat attempts. Our aim was to examine secondary mental health service contact following a presentation to emergency department with suicidal behaviours.

METHODS

A systematic review of papers published between 2000 and 2020 was undertaken. This identified 56 papers relating to 47 primary studies. Data were extracted and summarised separately by age group: (1) young people, (2) older adults and (3) adults and studies with participants of 'all ages'.

RESULTS

Studies in young people (n = 13) showed, on average, 44.8% were referred and 33.7% had contact with secondary mental health services within 4 weeks of emergency department discharge. In comparison, in adult/all ages studies (n = 34), on average, 27.1% were referred to and 26.2% had mental health service contact within 4 weeks. Only three studies presented data on contact with mental health services for older adults, and proportions ranged from 49.0% to 86.0%.

CONCLUSION

This review highlights poor utilisation of secondary mental health service following emergency department presentation for suicidal behaviours, and further research is needed to identify the reasons for this. Crucially, this information could assist in the allocation of resources to facilitate the timely implementation of suicide prevention services.

Predictive factors of nonfatal self-harm among community-dwelling older adults assessed for support services

BACKGROUND

Older adults receiving support services are a population at risk for self-harm due to physical illness and functional impairment, which are known risk factors. This study aims to investigate the relative importance of predictive factors of nonfatal self-harm among older adults assessed for support services in New Zealand.

METHODS

interRAI-Home Care (HC) national data of older adults (aged ≥ 60) were linked to mortality and hospital discharge data between January 1, 2012 and December 31, 2016. We calculated the crude incidence of self-harm per 100,000 person-years, and gender and age-adjusted standardized incidence ratios (SIRs). The Fine and Gray competing risk regression model was fitted to estimate the hazard ratio (HR; 95% CIs) of self-harm associated with various demographic, psychosocial, clinical factors, and summary scales.

RESULTS

A total of 93,501 older adults were included. At the end of the follow-up period, 251 (0.27%) people had at least one episode of nonfatal self-harm and 36,333 (38.86%) people died. The overall incidence of nonfatal self-harm was 160.39 (95% CI, 141.36-181.06) per 100,000 person-years and SIR was 5.12 (95% CI, 4.51-5.78), with the highest incidence in the first year of follow-up. Depression diagnosis (HR, 3.02, 2.26-4.03), at-risk alcohol use (2.38, 1.30-4.35), and bipolar disorder (2.18, 1.25-3.80) were the most significant risk factors. Protective effects were found with cancer (0.57, 0.36-0.89) and severe level of functional impairment measured by Activities of Daily Living (ADL) Hierarchy Scale (0.56, 0.35-0.89).

CONCLUSION

Psychiatric factors are the most significant predictors for nonfatal self-harm among older adults receiving support services. Our results can be used to inform healthcare professionals for timely identification of people at high risk of self-harm and the development of more efficient and targeted prevention strategies, with specific attention to individuals with depression or depressive symptoms, particularly in the first year of follow-up.

Learning from suicide deaths in Harris County, Texas

This study examined individual and community demographic characteristics surrounding suicides in one of the most populous counties in the United States. We paired medical examiner records with U.S. Census data and analyzed them using geospatial software. The majority of decedents were non-Hispanic, white males who died primarily of gunshot wounds. Salient age characteristics included interpersonal violence and depression among ages younger than 40. Despite lower incomes and education levels, areas with higher population density and racial/ethnic minorities had fewer suicides. Additional research should address depression among males and the elderly, interpersonal violence, firearm access, and culture.
