Psychiatric disorders and suicide risk among adults with disabilities: A nationwide retrospective cohort study

Monday peak is unique to suicide? Comparison of weekly distribution by causes of death using national representative cohort database

INTRODUCTION

The excess suicide mortality on Monday was reported in numerous studies. However, it is uncertain that the uneven weekly distribution of deaths is observed among suicide, or common among various causes of death.

METHODS

Weekly distributions of suicide and other causes of death from 2012 to 2017 in South Korea were compared. Logistic regression models were fitted to investigate the association between causes of death and day-of-the-week effects. We also fitted conditional logistic regression models after age and gender matching.

RESULTS

A total of 1,622,213 deaths, including 80,492 suicide decedents, were analyzed. A total of 16.0% of suicide deaths occurred on Monday, whereas 12.4% on Saturday and 13.0% on Sunday. Suicide decedents were more likely to die on Monday than other causes of deaths after controlling sociodemographic factors in unmatched data. However, there was no evidence of excess suicide deaths on Mondays than other days in contrast to matched death controls.

CONCLUSION

While the increase in mortality on Mondays was not unique to suicide, our findings have suicide prevention implications. Mental health practitioners should consider providing additional mental health resources on earlier working days. Workplace mental health programs to reduce psychological burdens of employees could help to prevent suicide during working days.

Disabled people's perceptions and experiences of accessing and receiving counselling and psychotherapy: a scoping review protocol

INTRODUCTION

Evidence indicates that, compared with their non-disabled counterparts, disabled people are likely to face greater mental health challenges as well as significant inequalities in accessing appropriate therapeutic support. Currently, little is known about how disabled people perceive and experience counselling and psychotherapy, what barriers/facilitators to therapy delivery and/or therapy participation exist for disabled clients and whether clinicians sufficiently adapt their practice to meet the needs of this diverse but marginalised population. In this paper, we outline a proposal for undertaking a scoping review that aims to identify and synthesise current research relating to disabled individuals' perceptions of accessibility and experiences of counselling and psychotherapy. The review aims to identify current gaps in the evidence base and inform how future research, practice and policy may develop and foster inclusive strategies and approaches which will support the psychological well-being of disabled clients accessing counselling and psychotherapy.

METHODS AND ANALYSIS

The undertaking and reporting of the proposed scoping review will be guided by the framework outlined by Arksey and O'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR) guidelines. Systematic searches of the PsycINFO, CINAHL, EMBASE, EBSCO and Cochrane Library electronic databases will be conducted. Reference lists of relevant studies will be reviewed to identify additional studies. Eligible studies will be limited to those published from 1 January 2010 to 31 December 2022 and in the English language. Empirical studies involving disabled individuals receiving and/or who have received a form of therapeutic intervention will be included. Data will be extracted, collated and charted, and will be summarised quantitatively through descriptive numerical analysis and qualitatively through a narrative synthesis.

ETHICS AND DISSEMINATION

The proposed scoping review of published research will not require ethical approval. Results will be disseminated through publication in a peer-reviewed journal.

Mental Health Concerns in Individuals With Developmental Disabilities: Improving Mental Health Literacy Trainings for Caregivers

Although approximately a third of individuals with intellectual and developmental disabilities (IDD) also experience a mental health concern, caregivers often miss early identification of these issues. In this perspective piece, we present an outline for a mental health literacy program that can enhance existing training approaches for caregivers of individuals with IDD. We describe three processes of the Mental Health Awareness and Advocacy (MHAA) curriculum and detail how it provides a strong preventative model to train caregivers to increase their mental health literacy. In describing these processes, we provide illustrative examples and conclude by providing a brief vignette that highlights how this process could be used by caregivers to help reduce mental health concerns in individuals with IDD.

Risk of COVID-19 and major adverse clinical outcomes among people with disabilities in South Korea

Background

Evidence regarding the risk of coronavirus disease (COVID-19) and the major adverse clinical outcomes of COVID-19 among people with disabilities (PwDs) is scarce.

Objective

This study investigated the association of disability status with the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test positivity and the risk of major adverse clinical outcomes among participants who tested positive for SARS-CoV-2.

Methods

This study included all patients (n = 8070) who tested positive for SARS-CoV-2 and individuals without COVID-19 (n = 121,050) in South Korea from January 1 to May 30, 2020. The study variables included officially registered disability status from the government, SARS-CoV-2 test positivity, and major adverse clinical outcomes of COVID-19 (admission to the intensive care unit, invasive ventilation, or death).

Results

The study participants included 129,120 individuals (including 7261 PwDs), of whom 8070 (6.3%) tested positive for SARS-CoV-2. After adjusting for potential confounding factors, PwDs had an increased risk of SARS-CoV-2 test positivity compared with people without disabilities (odds ratio [OR]: 1.36, 95% confidence interval [CI]: 1.24–1.48). Among participants who tested positive for SARS-CoV-2, PwDs were associated with an increased risk of major adverse clinical outcomes from COVID-19 compared to those without disabilities (OR: 1.43, 95% CI: 1.11–1.86).

Conclusions

PwDs had an increased risk of COVID-19 and major adverse clinical outcomes of COVID-19 compared with people without disabilities. Given the higher vulnerability of PwDs to COVID-19, tailored policy and management to protect against the risk of COVID-19 are required.

BMI, weight change, and incidence of disability among Korean adults: A nationwide retrospective cohort study

BACKGROUND

Little is known about the risk of acquired disability diagnosed by a physician in relation to baseline BMI and weight change, particularly in the Asian population.

OBJECTIVE

This study assessed the association of baseline BMI and weight change with incidence of disability.

METHODS

This study included 331,900 individuals aged ≥40 years who participated in two health-screening programs since 2002 or 2003 and who were followed up until 2013. This study measured the baseline BMI and weight change for two years and estimated the adjusted hazard ratio (aHR) of the risk of acquired disability diagnosed by a physician using a Cox proportional hazards model.

RESULTS

This study identified 1758 incident disability cases during an average follow-up period of 10.7 ± 1.3 years from baseline (9.1 ± 1.4 years from the follow-up health screening). Baseline underweight (BMI<18.5 kg/m²) was associated with an increased risk of acquired disability compared with those with normal BMI (aHR, 1.44; 95% confidence interval [CI], 1.14-1.83). The risk of acquired disability was higher in individuals with weight loss of 5-10% (aHR, 1.21; 95% CI, 1.04-1.40), weight loss of ≥10% (aHR, 1.61; 95% CI, 1.27-2.04), weight gain of 5-10% (aHR, 1.30; 95% CI, 1.12-1.52), or weight gain of ≥10% (aHR, 1.35; 95% CI, 1.09-1.75) compared to those with weight change of <5%.

CONCLUSION

This study demonstrated that baseline underweight and weight changes (both loss and gain) are associated with an increased risk of acquired disability.

Suicide risk within 1 year of dementia diagnosis in older adults: a nationwide retrospective cohort study

BACKGROUND

Although severe dementia could protect against suicide death by decreasing a person's capacity to implement a suicide plan, patients with early dementia may have better cognition, giving them more sustained insight into their disease and better enabling them to carry out a suicide plan. This study investigated suicide risk in older adults within 1 year of receiving a diagnosis of dementia.

METHODS

This study used National Health Insurance Service Senior Cohort data and included 36 541 older adults with newly diagnosed dementia (a Mini-Mental State Examination score ≤ 26 and a Clinical Dementia Rating score ≥ 1 or a Global Deterioration Scale score ≥ 3), including Alzheimer disease, vascular dementia and other/unspecified dementia, from 2004 to 2012. We selected older adults without dementia through 1:1 propensity-score matching using sex, age, comorbidities and index year, with follow-up throughout 2013. We estimated adjusted hazard ratios (AHRs) of suicide deaths within 1 year after diagnosis using a time-dependent Cox proportional hazards model.

RESULTS

We verified 46 suicide deaths during the first year after a dementia diagnosis. Older adults with dementia had an increased risk of suicide death compared to those without dementia (AHR 2.57; 95% confidence interval [CI] 1.49-4.44). Older adults with Alzheimer disease (AHR 2.50; 95% CI 1.41-4.44) or other/unspecified dementia (AHR 4.32; 95% CI 2.04-9.15) had an increased risk of suicide death compared to those without dementia. Patients with dementia but without other mental disorders (AHR 1.96; 95% CI 1.02-3.77) and patients with dementia and other mental disorders (AHR 3.22; 95% CI 1.78-5.83) had an increased risk of suicide death compared to patients without dementia. Patients with dementia and schizophrenia (AHR 8.73; 95% CI 2.57-29.71), mood disorders (AHR 2.84; 95% CI 1.23-6.53) or anxiety or somatoform disorders (AHR 3.53; 95% CI 1.73-7.21), respectively, had an increased risk of suicide death compared to patients with those conditions but without dementia.

LIMITATIONS

This study examined only elderly patients in South Korea, a population with a substantially higher suicide rate than the global population. Caution must be exercised when generalizing the results to populations with dissimilar backgrounds.

CONCLUSION

Patients with dementia had an increased risk of suicide death within 1 year after diagnosis compared to those without dementia.

Two Case Studies of Delusions Leading to Suicide, a Selective Review

Many questions pertaining to delusional disorder (DD) remain unanswered. It is unclear what syndromes to include under this category of psychotic illness and when to treat with antidepressants, cognitive therapy, or antipsychotic medication. DD is associated with psychiatric comorbidity, especially depression, and rates of suicidal behavior are high when the two conditions co-exist. In this selective review, we present two instances of suicide in the context of DD, one illustrating risks for the somatic subtype and the second, risks for the persecutory subtype. The frequency of suicidal behaviour in these two subtypes of DD is estimated at 8-21%. The literature suggests a prominent role for social emotions (shame, humiliation) in the pathway leading to suicide. In addition, risk factors found in our two patients point to factors such as poverty, living alone, vulnerable risk periods, stigma, and lack of trust in mental health services. Building trust may be the most effective preventive measure.
