ObjectiveBipolar disorder is associated with high risk of self-harm and suicide. We wanted to investigate risk factors for attempted suicide in bipolar patients.MethodThis was a cohort study of 6086 bipolar patients (60% women) registered in the Swedish National Quality Register for Bipolar Disorder 2004–2011 and followed-up annually 2005–2012. Logistic regression was used to calculate adjusted odds ratios for fatal or non-fatal attempted suicide during follow-up.ResultsRecent affective episodes predicted attempted suicide during follow-up (men: odds ratio = 3.63, 95% CI = 1.76–7.51; women: odds ratio = 2.81, 95% CI = 1.78–4.44), as did previous suicide attempts (men: odds ratio = 3.93, 95% CI = 2.48–6.24; women: odds ratio = 4.24, 95% CI = 3.06–5.88) and recent psychiatric inpatient care (men: odds ratio = 3.57, 95% CI = 1.59–8,01; women: odds ratio = 2.68, 95% CI = 1.60–4.50). Further, those with many lifetime depressive episodes were more likely to attempt suicide. Comorbid substance use disorder was a predictor in men; many lifetime mixed episodes, early onset of mental disorder, personality disorder, and social problems related to the primary group were predictors in women.ConclusionThe principal clinical implication of the present study is to pay attention to the risk of suicidal behaviour in bipolar patients with depressive features and more severe or unstable forms of the disorder.

Objective: To study the short-term risk of suicide after nonfatal deliberate self-harm and its association with coexisting mental disorders and with the method of self-harm used. Method: We used linked Swedish national registers to design a cohort study with 34,219 individuals (59% females) who were admitted to hospital in 2000-2005 after deliberate selfharm (ICD-10-defined). They were followed for 3-9 years. The studied outcome was completed suicide; Cox regression models yielded hazard ratios (HRs) for suicide risk. Temporal patterns were plotted with Kaplan-Meier survival curves, calculated separately for each mental disorder and for the method used at the previous selfharm event.Results: 1,182 subjects committed suicide during follow-up (670 males and 512 females). Coexisting bipolar disorder (in males, adjusted HR = 6.3; 95% confidence interval [CI], 3.8-10.3; in females, adjusted HR = 5.8; 95% CI, 3.4-9.7) and nonorganic psychotic disorder (in males, adjusted HR = 5.1; 95% CI, 3.5-7.4; in females, adjusted HR = 4.6; 95% CI, 2.8-7.7) implied the highest risk of suicide after previous self-harm. Hanging as index self-harm method was a strong predictor of later suicide in both males (adjusted HR = 5.3; 95% CI, 4.0-7.0) and females (adjusted HR = 4.5; 95% CI, 2.5-8.1). Of those with bipolar disorder who used a method other than poisoning at the index event, 20.4% had already committed suicide after 3-9 years. Conclusion: Individuals with severe mental disorders (affective and psychotic disorders) have a poor prognosis in the first years after hospital admission due to self-harm. The risk of subsequent suicide is higher after attempts by hanging and other self-injury methods (vs selfpoisoning). Aftercare for those with a self-harm episode should focus on treatment of the mental disorder present at the time of the episode.

Background Suicide screening is routine practice in psychiatric emergency (PE) departments, but evidence for screening instruments is sparse. Improved identification of nascent suicide risk is important for suicide prevention. The aim of the current study was to evaluate the association between the novel Colombia Suicide Severity Rating Scale Screen Version (C-SSRS Screen) and subsequent clinical management and suicide within 1 week, 1 month and 1 year from screening. Methods Consecutive patients (N = 18 684) attending a PE department in Stockholm, Sweden between 1 May 2016 and 31 December 2017 were assessed with the C-SSRS Screen. All patients (52.1% women; mean age = 39.7, s.d. = 16.9) were followed-up in the National Cause of Death Register. Logistic regression and receiver operating characteristic curves analyses were conducted. Optimal cut-offs and accuracy statistics were calculated. Results Both suicidal ideation and behaviour were prevalent at screening. In total, 107 patients died by suicide during follow-up. Both C-SSRS Screen Ideation Severity and Behaviour Scales were associated with death by suicide within 1-week, 1-month and 1-year follow-up. The optimal cut-off for the ideation severity scale was associated with at least four times the odds of dying by suicide within 1 week (adjusted OR 4.7, 95% confidence interval 1.5–14.8). Both scales were also associated with short-term clinical management. Conclusions The C-SSRS Screen may be feasible to use in the actual management setting as an initial step before the clinical assessment of suicide risk. Future research may investigate the utility of combining the C-SSRS Screen with a more thorough assessment.

Objective:The risk of suicide is elevated after discharge from a psychiatric hospital. This study aimed to investigate how recent suicidal behavior affects the risk of suicide in patients with different psychiatric diagnoses immediately after discharge. Methods: Registers with national coverage were linked to create a study cohort including all individuals discharged from psychiatric hospitals in Sweden from 1973 through 2009. Hazard ratios for discharge diagnoses were calculated. The risk of suicide within 30 days after discharge in each diagnostic category when suicidal behavior had been registered within 30 days before admission was estimated. Results: A total of 3,695 suicides occurred after 2,883,088 discharges. If recent suicidal behavior was registered, the risk of completed suicide increased prominently in all diagnostic categories, but particularly for schizophrenia (hazard ratio [HR] = 8.9; 95% CI, 6.4-12.4) and other nonorganic psychosis (HR = 6.8; 95% CI, 5.1-9.0). Patients suffering from depression had the highest overall risk of suicide postdischarge (HR = 3.0; 95% CI, 2.7-3.3). This finding applied especially to male patients with depression (HR = 4.5; 95% CI, 4.0-5.0) or with reaction to crisis (HR = 3.6; 95% CI 3.0-4.4). Conclusions:A distinct elevation of the risk of suicide was seen in all diagnostic groups if a recent self-harm event had occurred, particularly among patients with psychotic disorders. Overall, the immediate risk of suicide after discharge was high regardless of recent suicidal behavior. The findings in this study have relevance for clinical decisions about immediate after-care and treatment in connection with discharge from psychiatric inpatient care.
