Associations between suicidal ideation and health-related quality of life among community-dwelling stroke survivors: 2013-2017 Korea National Health and Nutrition Examination Survey.

PURPOSE: The study aimed to identify differences between individuals with stroke and the general population regarding socioeconomic, mental health, and Health-related quality of life (HRQOL) factors, and associations among Suicidal ideation (SI), HRQOL, and mental health. METHODS: Data of individuals with stroke (n = 592) and without stroke (n = 23,562) aged 20 or older from the 2013-2017 Korea National Health and Nutrition Examination Survey were analyzed. Chi-square tests examined differences in socioeconomic status, mental health, and HRQOL (EQ-5D) between groups. Independent associations between each EQ-5D dimension and SI were analyzed through multivariable logistic regression. RESULTS: Individuals with stroke were more likely to have problems on all EQ-5D dimensions. Significant univariate associations were identified between four EQ-5D dimensions and SI among individuals with stroke. Pain/discomfort (odds ratio [OR] = 1.32; 95% confidence interval [CI], 1.01-1.75, p = 0.048) and anxiety/depression (OR = 4.66; 95% CI, 3.69-5.89, p < .0001) of the EQ-5D were associated with SI when adjusting for all socioeconomic variables; anxiety/depression (OR = 2.80; 95% CI, 2.18-3.60, p < .0001) was the only risk factor for SI after controlling for socioeconomic and mental health variables. CONCLUSION: Individuals with stroke showed higher rates for problems on the EQ-5D, SI, and depression compared to the general population. They also demonstrated significant associations between SI and each EQ-5D dimension except physical activity, especially pain/discomfort and depression/anxiety. The study's findings can be referred to when predicting suicide risk in individuals with stroke by analyzing their EQ-5D scores.

How COVID-19 Affected Healthcare Workers in the Hospital Locked Down due to Early COVID-19 Cases in Korea.

BACKGROUND: The healthcare workers (HCWs) were exposed to never-experienced psychological distress during the early stage of the coronavirus disease 2019 (COVID-19) pandemic. The aim of this study was to investigate how the COVID-19 pandemic affected the mental health of HCWs during the hospital lockdown period due to mass healthcare-associated infection during the early spread of COVID-19. METHODS: A real-time online survey was conducted between April 14-18, 2020 among HCWs who worked at the university hospital where COVID-19 was confirmed in a patient, and the hospital was shut down for 3 weeks. Along with demographic variables and work-related information, psychological distress was measured using the Generalized Anxiety Disorder-7 (GAD-7), the Patient Health Questionnaire-9 (PHQ-9), the Maslach Burnout Inventory-General Survey scale, and the Stress and Anxiety to Viral Epidemics-9. RESULTS: The HCWs working in the cohort ward and those who have experienced social discrimination had significantly higher level of depression (PHQ-9 score; 5.24 ± 4.48 vs. 4.15 ± 4.38; P < 0.01 and 5.89 ± 4.78 vs. 3.25 ± 3.77; P < 0.001, respectively) and anxiety (GAD-7 score; 3.69 ± 3.68 vs. 2.87 ± 3.73; P < 0.05 and 4.20 ± 4.22 vs. 2.17 ± 3.06; P < 0.001, respectively) compared to other HCWs. Worries regarding the peer relationship and the skepticism about job were associated with depression (odds ratio [OR], 1.39; 95% confidence interval [CI], 1.07-1.79; P < 0.05 and OR, 1.69; 95% CI, 1.31-2.17; P < 0.001, respectively) and anxiety (OR, 1.73; 95% CI, 1.21-2.49; P < 0.01 and OR, 1.54; 95% CI, 1.09-2.17; P < 0.05, respectively), while fear of infection or worsening of health was not. Path analysis showed that work-related stress associated with the viral epidemic rather than anxiety about the viral epidemic mainly contributed to depression. CONCLUSION: The present observational study indicates that mental health problems of HCWs exposed to COVID-19 are associated with distress in work and social relationship. Early intervention programs focusing on these factors are necessary.

Pessimistically biased perception in panic disorder during risk learning.

BACKGROUND: Despite the well-known association between anxiety and risk-avoidant decision making, it is unclear how pathological anxiety biases risk learning. We propose a Bayesian inference model with bias parameters of prior, learning, and perception during risk learning in individuals with pathological anxiety. METHODS: Patients with panic disorder (PD, n = 40) and healthy control subjects (n = 84) completed the balloon analog risk task (BART). By fitting our computational model of three bias parameters (prior belief, learning rate, and perceptual bias) to the participants' behavior, we estimated the degree of bias in risk learning and its relationship with anxiety symptoms. RESULTS: Relative to the healthy control subjects, the pathologically anxious participants exhibited a biased underestimation of perceptual evidence rather than differences in priors and learning rates. The degree of perceptual bias was correlated with the anxiety and depression symptom severity in the patients with PD. Furthermore, our proposed model was the winning model for BART data in an external data set from different patient groups. CONCLUSIONS: Our results showed that individuals with pathological anxiety demonstrate perceptual bias in evidence accumulation, which may explain why patients with anxiety overestimate risk in their daily lives. This clarification highlights the importance of interventions focusing on perceptual bias, such as enhancing the clarity of favorable outcome probabilities.

Emotion-Induced Topological Changes in Functional Brain Networks.

In facial expression perception, a distributed network is activated according to stimulus context. We proposed that an interaction between brain activation and stimulus context in response to facial expressions could signify a pattern of interactivity across the whole brain network beyond the face processing network. Functional magnetic resonance imaging data were acquired for 19 young healthy subjects who were exposed to either emotionally neutral or negative facial expressions. We constructed group-wise functional brain networks for 12 face processing areas [bilateral inferior occipital gyri (IOG), fusiform gyri (FG), superior temporal sulci (STS), amygdalae (AMG), inferior frontal gyri (IFG), and orbitofrontal cortices (OFC)] and for 73 whole brain areas, based on partial correlation of mean activation across subjects. We compared the topological properties of the networks with respect to functional distance-based measures, global and local efficiency, between the two types of face stimulus. In both face processing and whole brain networks, global efficiency was lower and local efficiency was higher for negative faces relative to neutral faces, indicating that network topology differed according to stimulus context. Particularly in the face processing network, emotion-induced changes in network topology were attributable to interactions between core (bilateral IOG, FG, and STS) and extended (bilateral AMG, IFG, and OFC) systems. These results suggest that changes in brain activation patterns in response to emotional face stimuli could be revealed as changes in the topological properties of functional brain networks for the whole brain as well as for face processing areas.

Modulation of prefrontal-cingulate connectivity in affective processing of children with experiences of ostracism.

BACKGROUND: The anterior cingulate cortex (ACC) has been shown to be involved in emotional distress induced by social exclusion and the ventrolateral prefrontal cortex (VLPFC) in the regulation or inhibition of the distress. Here, we examined modulation of effective connectivity between the regions in response to emotional feedback in children with experiences of ostracism in their everyday life. METHODS: In functional magnetic resonance imaging experiments, 10 ostracized children and 11 control children were provided emotional feedback inducing negative or positive affective states. We employed effective connectivity analysis to explore connectivity models comprising the VLPFC and ACC, and to estimate connectivity parameters over the models. RESULTS: In spite of psychological impacts on the ostracized children, behavioral data showed that their emotional responses did not deviate from the control children in response to the emotional feedback. The VLPFC to ACC connectivity was modulated only in the ostracized children, such that the modulation may help them regulate their emotional responses. CONCLUSIONS: The findings suggest that the effects of ostracism experiences on affective processing can be revealed in terms of modulation of prefrontal-cingulate connectivity.

Association of fracture risk with benzodiazepine among adults in South Korea.

This study examined the association between fracture and benzodiazepine (BZD) prescription in Korean adults using case-crossover (CCO) and self-controlled case-series (SCCS) designs, which have the advantage to control confounding bias, such as individual characteristics. Patients with fracture were defined as patients who visited the emergency room and orthopedics department with the ICD-10 diagnosis code for fracture. Fractures due to motor vehicle accidents and stroke were excluded. Whereas the CCO design presented odds ratio (OR) using a conditional logistic regression model, SCCS design showed incidence rate ratio (IRR) using a conditional Poisson regression model. The concomitant drugs that can affect the fracture were adjusted. Sensitivity analysis and subgroup analysis by age (elderly vs. nonelderly), action mechanism (short-acting vs. long-acting), and prescription duration (short-term user vs. long-term user) were conducted. The adjusted OR (AOR) for control period I (prior to 90 days from case) was 1.39 (95% CI=1.25-1.54) for all BZD prescriptions. The adjusted ORs for other control periods showed similar trends. The adjusted IRRs (AIRR) during the first 4 weeks, 4-8 weeks, 8-12 weeks, and 12-16 weeks from new BZD use were 1.46 (95% CI=1.28-1.66), 1.23 (95% CI=1.01-1.49), 1.09 (95% CI=0.86-1.37), and 1.38 (95% CI=1.07-1.77), respectively. Regardless of age group, action mechanism, or prescription duration, fracture risk was higher during case period than control. The risk for fracture was higher in both elderly and non-elderly people with BZD prescription than in those without BZD prescription. Careful monitoring for people who start BZD treatment and further research in the non-elderly is required.

Clinical Characteristics of the Suicide Attempters Who Refused to Participate in a Suicide Prevention Case Management Program.

Case management interventions for suicide attempters aimed at helping adjust their social life to prevent reattempts have high nonparticipation and dropout rates. We analyzed the clinical characteristics of the group who refused to participate in the suicide prevention program in Korea. A total of 489 patients with a suicide attempt who visited Uijeongbu St. Mary's Hospital, the Catholic University of Korea, from December 2009 to December 2013 were analyzed. All patients were divided into the participation group (n = 262) and the refusal group (n = 227) according to their participation in the case management program. Demographic and clinical characteristics of each group were examined. Results showed that the refusal group had low risks for suicide in terms of risk factors related with psychopathologies and presenting suicide behavior. That is, the refusal group had less patients with co-morbid medical illnesses and more patients with mild severity of depression compared to the participation group. However, the refusal group had more interpersonal conflict, more isolation of social integrity, and more impaired insight about suicide attempt. The results suggest that nonparticipation in the case management program may depend upon the patient's impaired insight about the riskiness of suicide and lack of social support.

In-depth investigation for prescribing trends of benzodiazepines in South Korea.

This study aimed to investigate national prescription trends of benzodiazepines (BZD) for adults between 2007 and 2011 using Health Insurance Review and Assessment Service (HIRA) database in South Korea. Data analysis was performed by claim unit or patient unit. For the analysis of patient unit, each claim was merged by the same patient. Defined daily dose (DDD) was used to analyze the data in terms of dose and periods of BZD prescription. We identified a total of 22,361,449 adult patients who had BZD prescription at least once in 1,989,263 claims during 5 years. The average national BZD prescription prevalence for 1 year was 23.7%, 7.9%, 4.7%, and 3.2% of >= 1 day supply, >= 30 days supply, >= 90 days supply, and >= 180 days supply, respectively. The trends for 5 years were very similar. Among study population, 87.7% visited only non-psychiatric departments and the most frequent indication was gastrointestinal related diseases. BZD consumption expressed as DDDs per 1,000 inhabitants per day was 109.2. BZD consumption tended to be ~ 4 x higher in elderly than that of non-elderly (268.6 vs. 60.0 in male and 367.7 vs. 90.9 in female). Our study indicated the possibilities for inappropriate prescription of BZD, and the limitation policy on continuous prescription over 30 days supply did not seem to be effective. The effective interventions including an educational program for appropriate prescription of BZD should be considered.

Neural changes associated with emotion processing in children experiencing peer rejection: a functional MRI study.

This study was performed to investigate differences between children who did and did not experience peer rejection in psychological state through surveys and in emotion processing during an interpersonal stress challenge task to reflect naturalistic interpersonal face-to-face relationships. A total of 20 right-handed children, 10 to 12 yr of age, completed self-rating questionnaires inquiring about peer rejection in school, depression, and anxiety. They then underwent an interpersonal stress challenge task simulating conditions of emotional stress, in reaction to positive, negative and neutral facial expression stimuli, using interpersonal feedbacks, and functional magnetic resonance imaging (FMRI) for an analysis of neural correlates during the task. Ten were the peer-rejection group, whereas the remainder were the control group. Based on the behavioral results, the peer-rejection group exhibited elevated levels of depression, state anxiety, trait anxiety and social anxiety as compared to the control group. The FMRI results revealed that the peer-rejection group exhibited greater and remarkably more extensive activation of brain regions encompassing the amygdala, orbitofrontal cortex and ventrolateral prefrontal cortex in response to negative feedback stimuli of emotional faces. The different brain reactivities characterizing emotion processing during interpersonal relationships may be present between children who do and do not experience peer rejection.

Psychometric Properties of the Korean Version of THINC-integrated Tool (THINC-it-K): A Tool for Screening Assessment of Cognitive Function in Patients with Major Depressive Disorder.

Objective: : The present study was performed to investigate the validity and reliability of the Korean version of the THINC-it tool (THINC-it-K) in adult patients with major depressive disorder (MDD). Methods: : Subjects aged 19-65 years with recurrent MDD experiencing moderate to severe major depressive episode (n = 44) were evaluated and compared to age and sex matched healthy controls (n = 44). Subjects completed the THINC-it-K which includes variants of the Identification Task (IDN) using Choice Reaction Time, One-Back Test, Digit Symbol Substitution Test, Trail Making Test-Part B, and the Perceived Deficits Questionnaire for Depression-5-item (PDQ-5-D). Results: : A total of 75.0% of patients with MDD exhibited cognitive performance 1 standard deviation or below. The differences in Spotter (p = 0.001), Codebreaker (p = 0.001), PDQ-5-D (p ＜ 0.001) and objective THINC-it-K composite score (p = 0.002) were significant between the two groups. Concurrent validity of the THINC-it-K based on a calculated composite score was good (r = 0.856, p ＜ 0.001), and ranges for each component tests were from 0.076 (IDN) to 0.928 (PDQ-5-D). Conclusion: : The THINC-it-K exhibits good reliability and validity in adults with MDD. It could be a useful tool for the measurement of cognitive deficits in persons with MDD and should be implemented in clinical practice.

Efficacy and Safety of Lurasidone vs. Quetiapine XR in Acutely Psychotic Patients With Schizophrenia in Korea: A Randomized, Double-Blind, Active-Controlled Trial.

OBJECTIVE: This study was performed to evaluate the efficacy and safety of lurasidone (160 mg/day) compared to quetiapine XR (QXR; 600 mg/day) in the treatment of acutely psychotic patients with schizophrenia. METHODS: Patients were randomly assigned to 6 weeks of double-blind treatment with lurasidone 160 mg/day (n=105) or QXR 600 mg/day (n=105). Primary efficacy measure was the change from baseline to week 6 in Positive and Negative Syndrome Scale (PANSS) total score and Clinical Global Impressions severity (CGI-S) score. Adverse events, body measurements, and laboratory parameters were assessed. RESULTS: Lurasidone demonstrated non-inferiority to QXR on the PANSS total score. Adjusted mean±standard error change at week 6 on the PANSS total score was -26.42±2.02 and -27.33±2.01 in the lurasidone and QXR group, respectively. The mean difference score was -0.91 (95% confidence interval -6.35-4.53). The lurasidone group showed a greater reduction in PANSS total and negative subscale on week 1 and a greater reduction in end-point CGI-S score compared to the QXR group. Body weight, body mass index, and waist circumference in the lurasidone group were reduced, with significantly lower mean change compared to QXR. Endpoint changes in glucose, cholesterol, triglycerides, and low-density lipoprotein levels were also significantly lower. The most common adverse drug reactions with lurasidone were akathisia and nausea. CONCLUSION: Lurasidone 160 mg/day was found to be non-inferior to QXR 600 mg/day in the treatment of schizophrenia with comparable efficacy and tolerability. Adverse effects of lurasidone were generally tolerable, and beneficial effects on metabolic parameters can be expected.

Psychometric properties of the Korean version of the Interpersonal Sensitivity Measure (IPSM-K).

The aim of this study was to investigate the psychometric properties of a Korean version of Interpersonal Sensitivity Measure (IPSM). A Korean version of the IPSM (IPSM-K) was produced through forward translation, reconciliation, and back translation. A total of 338 healthy, non-clinical participants were selected through screening and clinical interview, and they each were given a set of questionnaires including IPSM-K. All subscales, as well as a full-scale IPSM-K showed satisfactory internal consistency (Cronbach's alpha=0.73-0.83 and 0.94, respectively). Test-retest reliability at 2-week intervals was significant, with coefficient r ranging between .80 and .94. In terms of convergent validity, IPSM-K showed the significant positive correlation with sociotropy and autonomy subscale of Personal Style Inventory-II, as well as with neuroticism subscale of Neuroticism Extraversion Openness-Personality Inventory. IPSM-K had no correlation with Social Desirability Scale, thus demonstrated divergent validity with social desirability. A factor analysis of the scale was conducted and five factors emerged (low self-confidence, interpersonal awareness, lack of assertiveness/separation anxiety, interpersonal vulnerability, and need for approval). This study demonstrated that IPSM-K could be useful in assessing interpersonal sensitivity in Korean population.

Symptom severity of panic disorder associated with impairment in emotion processing of threat-related facial expressions.

AIM: To compare emotion recognition patterns between patients with panic disorder (PD) and healthy volunteers and to analyze the correlation between the degree of emotion recognition impairment and symptom severity in patients with PD. METHODS: Twenty-four patients with PD and 20 healthy controls were tested with a facial emotional expression recognition task involving four basic emotions (i.e. happiness, sadness, anger, and fear). Emotion recognition measures included the recognition threshold, response time, response time of correctly classified emotions (response time_crt), and recognition error. An average of all four emotions for each emotion recognition measure was compared between the two groups and then a comparison of recognition measures for each specific emotion was conducted. The correlations between severity of the State-Trait Anxiety Inventory, Beck Depression Inventory (BDI), and Panic Disorder Severity Scale with emotion recognition indices were also analyzed. RESULTS: Average recognition threshold was significantly higher in the PD group compared to the control group. In the PD group, there was a non-significant trend of increase in the emotion recognition threshold for fear and the response time for anger compared with the control group. In the correlation analysis, higher trait anxiety was associated with slower response time_crt for anger and a higher BDI score was associated with slower response times and response time_crt for happiness and anger. CONCLUSION: This study suggests that symptom severity of PD might be associated with impairment in emotion processing of threat-related facial expressions.

Psychometric properties of the Korean version of stanford acute stress reaction questionnaire.

The present study aimed to examine the psychometric properties of the Korean version of Stanford Acute Stress Reaction Questionnaire (SASRQ). A Korean version of the SASRQ was produced through forward translation, reconciliation, and back translation. A total of 100 healthy, non-clinical participants were selected through screening and clinical interview, and they each were given a set of questionnaires including SASRQ. Psychometric properties of SASRQ were then examined through statistical analyses. Full-scale and subscales of SASRQ yielded excellent internal consistency (Cronbach's alpha=0.98 and 0.78-0.95, respectively). Test-retest reliability at 2-week intervals was satisfactory, with coefficient r ranging between 0.47 and 0.71. Convergent validity was also demonstrated by strong correlations between SASRQ and other trauma-related questionnaires. Correlation with Social Desirability Scale, however, was not found to be significant; thus evidenced divergent validity. The Korean version of SASRQ appears to be a reliable and valid measurement tool for assessing symptoms of acute stress disorder. Including clinical samples for comparison with controls would be necessary in future studies.

Trajectories of self-rated health among community-dwelling individuals with depressive symptoms: A latent class growth analysis.

BACKGROUND: This study identified differences between individuals with and without depression regarding demographic and socioeconomic variables, health behavior, health status, health care utilization, and self-rated health (SRH) to identify the depressed group's SRH trajectories. METHODS: Data of individuals with (n = 589) and without (n = 6856) depression aged ≥20 from the 2013-2017 Korean Health Panel were analyzed. A chi-square test and t-tests examined differences in demographic and socioeconomic variables, health behaviors, health status, health care utilization, and the mean of SRH. Latent Growth Curve and Latent Class Growth Modeling identified SRH development trajectories and the most suitable latent classes explaining the trajectories, respectively. Multinomial logistic regression determined the predicting factors that classified latent classes. RESULTS: The depressed group had a lower mean SRH than the non-depressed group among most variables. Three latent classes were identified, each showing different SRH trajectories. Body-mass index and pain/discomfort were predicting factors for the "poor" classes compared with the "moderate-stable" class; older age, less national health insurance, less physical activity, more pain/discomfort, and more hospitalization were predictors for the "poor-stable" class. The depressed group's mean SRH was "poor." LIMITATIONS: Latent Class Growth Modeling in individuals with depression was based on experimental data; however, it needed to review other sample data to identify similar types of latent classes to those suggested in the current study. CONCLUSIONS: Predictors of the "poor-stable" class that were identified in this study can contribute to the formulation of intervention plans for the health and welfare of individuals with depression.

Elderly suicide attempters by self-poisoning in Korea.

BACKGROUND: Suicide is a major public health concern. The elderly have the highest rate of suicide and they make more lethal suicide attempts and have fewer psychiatric interventions than young people. Furthermore, they have old-age specific psychosocial difficulties. The present study investigated psychosocial risk factors and characteristics of an index suicide attempt of the elderly suicide attempters. METHODS: Subjects included 388 patients who were admitted to the emergency room following self-poisoning. Two age groups were defined: younger patients (aged less than 65 years) and older patients (aged over 65 years). Data including demographic factors, suicidal risk factors and information about the current suicide attempt were obtained from a retrospective chart review. RESULTS: The number of suicide attempters over the age of 65 years old was 57, and their mean age was 73.5 ± 7.5 years. The elderly patients had more underlying medical illnesses than the under-65 group (p < 0.001). Depression was the most common psychiatric diagnosis. Psychotropics were the most commonly ingested drugs in both groups, but the use of pesticides was more notable in the elderly. The elderly suicide attempters had higher risk-rating scores (p < 0.001) and lower rescue-rating scores (p = 0.014) than the under-65 group. Male-to-female ratio of the elderly group was nearly 1:1 unlike the under-65 group (p = 0.004). CONCLUSION: Elderly suicide attempters had different psychosocial stressors such as physical illness and more lethal suicide attempts. Our study suggests the need for development of specific preventive strategies and management guidelines for the elderly suicide attempters.

Time to discontinuation among the three second-generation antidepressants in a naturalistic outpatient setting of depression.

AIM: This study compared the discontinuation time among the three second-generation antidepressants (paroxetine, venlafaxine, and mirtazapine) in a naturalistic setting for outpatient treatment of depression. METHODS: This study used data from retrospectively reviewed medical records of patients admitted to an outpatient psychiatric clinic between January 2003 and December 2005. Patient groups (paroxetine-, venlafaxine-, and mirtazapine-treated) were compared with each other with regard to their discontinuation times for a 6-month period after treatment initiation. The data were analyzed, using a Kaplan-Meier survival analysis, and a Cox proportional hazards regression model. RESULTS: There were no significant differences in discontinuation times among the three second-generation antidepressants during the 6-month period after initiation of drug therapy. CONCLUSIONS: In a naturalistic setting for the care of depression, it seems that there are no differences in discontinuation times among these three second-generation antidepressants.

High Work-Related Stress and Anxiety as a Response to COVID-19 Among Health Care Workers in South Korea: Cross-sectional Online Survey Study.

BACKGROUND: The COVID-19 outbreak had a severe impact on health care workers' psychological health. It is important to establish a process for psychological assessment and intervention for health care workers during epidemics. OBJECTIVE: We investigated risk factors associated with psychological impacts for each health care worker group, to help optimize psychological interventions for health care workers in countries affected by the COVID-19 pandemic. METHODS: Respondents (n=1787) from 2 hospitals in Korea completed a web-based survey during the period from April 14 to 30, 2020. The web-based survey collected demographic information, psychiatric history, and responses to the 9-item Stress and Anxiety to Viral Epidemics (SAVE-9), 9-item Patient Health Questionnaire (PHQ-9), and 7-item Generalized Anxiety Disorder-7 (GAD-7) scales. We performed logistic regression to assess contributing factors as predictor variables, using health care workers' depression as outcome variables. RESULTS: Among 1783 health care workers, nursing professionals had significantly higher levels of depression (PHQ-9 score: meannurse 5.5, SD 4.6; meanother 3.8, SD 4.2; P<.001), general anxiety (GAD-7 score: meannurse 4.0, SD 4.1; meanother 2.7, SD 3.6; P<.001), and virus-related anxiety symptoms (SAVE-9 score: meannurse 21.6, SD 5.9; meanother 18.6, SD 6.3; P<.001). Among nursing professionals, single workers reported more severe depressive symptoms than married workers (PHQ-9 score ≥10; meannurse 20.3%; meanother 14.1%; P=.02), and junior (<40 years) workers reported more anxiety about the viral epidemic (SAVE-9 anxiety score; meannurse 15.6, SD 4.1; meanother 14.7, SD 4.4; P=.002). Logistic regression revealed that hospital (adjusted odds ratio [OR] 1.45, 95% CI 1.06-1.99), nursing professionals (adjusted OR 1.37, 95% CI 1.02-1.98), single workers (adjusted OR 1.51, 95% CI 1.05-2.16), higher stress and anxiety to the viral infection (high SAVE-9 score, adjusted OR 1.20, 95% CI 1.17-1.24), and past psychiatric history (adjusted OR 3.26, 95% CI 2.15-4.96) were positively associated with depression. CONCLUSIONS: Psychological support and interventions should be considered for health care workers, especially nursing professionals, those who are single, and those with high SAVE-9 scores.

Hospital-Based Case Management for Suicide High-Risk Group Using Delphi Survey.

OBJECTIVE: As of 2019, suicide is serious problem in Korea, with the highest suicide rate among OECD countries. To reduce suicide rates Emergency Department Based Post-Suicide Attempt Case Management carried out with government funding in South Korea, but it is insufficient to address the issue. Aim of this study is to prevent suicide attempts through continuous provision of mental health services even after discharge from acute care. METHODS: We selected 15 mental health specialists who are multidisciplinary experts in Suicide Prevention. Two-round Delphi survey was conducted on them to reach an agreement for hospital-based case management. RESULTS: The first Delphi survey consisted of 8 areas and 39 questions. Among them, 30 questions draw agreement above the reference value. The second Delphi survey, consisted of 37 questions, resulted in 32 above-standard questions. CONCLUSION: Consensus was reached in most category of the Hospital Based Case Management for Suicide High-Risk Group. Core of the developed plan was to provide services to patients who visited the hospital, pursue the stability and universalization of services through a medical insurance fee system. In the future, hospital-based case management service will be implemented as a new model contributing to the reduction of suicide rates in Korea.

Risk Factors for Serious Suicide Attempts with High Medical Severity.

OBJECTIVES: his study investigated the risk factors leading to serious suicide attempts with high medical severity. METHODS: Nine hundred and eighty-two patients who visited the emergency room after attempting suicide were divided into two groups: suicide attempters with high medical severity (25.3%) and those with low medical severity (74.7%). Demographic variables, clinical characteristics, and factors related to each suicide attempt were compared between the two groups. Multivariate logistic regression analysis was conducted to investigate risk factors for high medical severity in patients' current suicide attempts. RESULTS: The results show that suicide attempters with high medical severity had more severe depression and psychological disturbances such as agitation, intense emotions, and self-reproach. Suicide attempters with high medical severity also had more serious risk factors for suicide such as repetitive/intense/continuous thoughts of suicide, suicidal planning, and a stronger wish to die. School/work problems and physical illnesses were related to high medical severity with more lethal methods. Logistic regression demonstrated that school/work problems, total risk rating, severity of suicidal ideation, and agitation were risks for more serious suicide attempts, whereas more frequent lifetime suicide attempts were a protective factor. CONCLUSION: This study demonstrates that suicide attempters with high medical severity had more severe psychopathologies and risk factors related to suicidal behavior than those with low medical severity.
