Suicide in hospitalized early psychosis patients at the time of discharge from hospital: An exploratory study of attempters and nonattempters

Prevalence of suicidal ideation and suicide attempts in individuals with psychosis and bipolar disorder in South Asia: systematic review and meta-analysis

BACKGROUND

Suicidal ideation and attempts are growing public health concerns globally. Evidence from high-income countries suggests that individuals with psychosis and bipolar disorder are at increased risk of suicidal ideation and attempts, but there is a scarcity of evidence from South Asia.

AIMS

To estimate the prevalence of suicidal ideation and attempts in individuals with psychosis and bipolar disorder in South Asia.

METHOD

In this systematic review and meta-analysis, four databases (PsycINFO, Web of Science, EMBASE and Medline) were searched until December 2022. Pooled prevalence was estimated with random-effects models. Heterogeneity was quantified with the I2-statistic.

RESULTS

The pooled sample size across the 21 studies was 3745 participants, 1941 (51.8%) of which were male. The pooled prevalence of suicide attempts in South Asian people with either psychosis or bipolar disorder was 22% (95% CI 17-27; n = 15). The pooled prevalence of suicidal ideation with psychosis or bipolar disorder combined was 38% (95% CI 27-51; n = 10). Meta-regression, subgroup and sensitivity analysis showed that the pooled prevalence estimates for both suicide attempt and ideation remained unaffected by variations in critical appraisal ratings and study designs. Only one study reported data on suicide-related deaths.

CONCLUSIONS

One in four individuals diagnosed with psychosis or bipolar disorder have reported suicide attempts, whereas up to one in three have experienced suicidal ideation. These findings underscore the urgent need for clinicians to regularly assess and monitor suicidal ideation and attempts among individuals with these disorders in South Asia.

Suicide behavior is associated with childhood emotion dysregulation but not trait impulsivity in first episode psychosis

Historically, research on suicide behavior has not included those experiencing first episode psychosis (FEP), hindering prevention efforts for this population. Emotion dysregulation and impulsivity represent two mechanisms that contribute to suicide, but these have not been examined in FEP. We hypothesize that the combination of trait impulsivity and childhood emotion dysregulation are associated with suicide behavior (SB) and ideation (SI) in those experiencing FEP. Participants were recruited from an Early Psychosis Program (N=80, ages 12-32, 65% male). Clinician ratings of symptoms and history of SI and SB were obtained at baseline. Participants also completed self-report measures of childhood emotion dysregulation and trait impulsivity. Regression analyses examined whether childhood emotion dysregulation and trait impulsivity individually or in combination were associated with SI and SB, and the severity of SI and SB. Childhood emotion dysregulation was significantly associated with a history of SB and its severity, but not SI. Attention impulsivity was associated with the severity of SI. However, other impulsivity types, and interactions were not associated with a history of SI or SB. This suggests childhood emotion dysregulation is a potential target for prevention of SB in FEP, while trait impulsivity may be less important in this effort.

Psychiatric Hospitalization after Emergency Treatment for Deliberate Self-Harm is Associated with Repeated Deliberate Self-Harm

The objective of this study was to evaluate whether treatment at a psychiatric hospital reduces the risk of repeating parasuicide. Participants were 4,483 parasuicide patients admitted to an emergency department between July 2003 and March 2012. We analyzed the effectiveness of psychiatric hospitalization in preventing repeated parasuicide. We adjusted for background factors using multivariate logistic regression. Effects of psychiatric hospitalization upon the likelihood of repeated parasuicide within 1 year varied by age (especially those aged <35 years), indicating that hospitalization was a significant risk factor. We must be mindful of the risk of repeated parasuicide following discharge in young patients and to provide them with ongoing outpatient care and multimodal support.

A longitudinal investigation of the Concise Health Risk Tracking Self-Report (CHRT-SR) in suicidal patients during and after hospitalization

The Concise Health Risk Tracking Self-Report (CHRT-SR) scale is a brief self-report instrument to assess suicide risk. Initial investigations have indicated good psychometric properties in psychiatric outpatients. The aims of this paper were to examine the construct validity and factor structure of the twelve- (CHRT-SR12) and seven-item (CHRT-SR7) versions and to test if clinically expected within-person changes in suicide risk over time were measurable using the CHRT-SR in two study cohorts hospitalized for suicidal ideation or behavior: (1) patients with major depressive disorder (MDD) who participated in a psychological intervention trial, n = 65, and (2) participants with bipolar disorder or MDD in an observational study, n = 44. The CHRT-SR12 and self-report measures of hopelessness, depression, and positive psychological states were administered during admission and several times post-discharge. Both versions showed good internal consistency in inpatients and confirmed the three-factor structure (i.e., hopelessness, perceived lack of social support and active suicidal ideation and plans) found in outpatients. CHRT-SR scores had strong correlations with negative and positive affective constructs in the expected directions, and indicated decreases in suicide risk following discharge, in line with clinical expectations. The CHRT-SR12 and CHRT-SR7 are promising self-report measures for assessing suicide risk in very high-risk patient populations.
