Suicidal behaviour is a major public health problem that needs to be tackled by all health agents including mental health nurses. Aims: The purpose of this study was to analyse the relationship between demographic and clinical characteristics and different kinds of suicidal behaviour with a nurse-led suicide prevention programme. Methods: The design was a cross-sectional study, performed in the region of Osona (Catalonia) in the five-year period 2013–2017. Suicidal behaviour was classified as suicidal ideation, interrupted self-directed violence, suicide attempt or completed suicide. Results: The sample included 753 patients (of whom 53 completed suicide) who experienced 931 suicidal behaviour episodes. Men represented only 38.4% of the sample but 81.1% of completed suicides. Mental disorders were associated with suicidal behaviour in 75.4% of the sample. Two thirds (66.4%) of the individuals (0.8% (n = 4) of whom completed suicide) were participants in a nurse-led suicidal behaviour case management programme. Conclusion: The main risk factors were being a woman for suicidal behaviour and being a man and being older for completed suicide. Mental disorders, widowhood and retirement were also associated with completed suicide. The completed suicide rate was lower among participants in the nurse-led programme.

(1) Aims: To analyse the relationship between demographic and clinical characteristics and particular kinds of suicidal behaviour and its relationship with a nurse-led suicide prevention program. (2) Methods: A 5-year cross-sectional study design. Study performed in the region of Osona (Catalonia) during 2013-2017. Suicidal behaviour was classified as suicidal ideation, interrupted self-directed violence, suicide attempt and completed suicide. (3) Results: The sample included 753 patients ─ of whom 53 died by suicide─ and encompassed 931 suicidal behaviour episodes. Men represented 38.4% of the sample but 81.1% of deaths by suicide. Mental disorders were associated with suicidal behaviour in 75.4% of the sample. 66.4% of the individuals were engaged in the nurse-led Suicidal Behaviour Case Management Program, of which 0.8% (n=4) died by suicide. (4) Conclusion: The main risk factors were female sex for suicidal behaviour, and male sex and older age for suicide. Mental disorders, widowhood and retirement were also associated with suicide. A high proportion of patients was engaged to the nurse-led suicide prevention program with a low proportion of suicides.

<p><strong>Background:</strong> Suicide rates are higher in the prison environment than in the general population. Prevention involves strategies to promote mental health, early diagnosis, treatment and identification of precipitating factors. The aim of this study is to evaluate the effectiveness of a psychoeducational group intervention performed by rehabilitation professionals to decrease the number of suicidal behaviors in the penitentiary environment.</p><p><strong>Methods:</strong> This study has been designed as a multicentric, randomized, two parallel-group, controlled trial. The study population will be male and female inmates of nine prisons of Catalonia (Spain). The primary outcome will be the total number of suicidal behaviours for 12 months of follow-up. Secondary outcomes will be suicide risk evaluated with the international neuropsychiatric interview (MINI); the severity of suicidal ideations assessed with the Columbia-suicide severity rating scale (C-SSRS), the presence of depressive and anxiety symptoms [Hamilton depression rating scale (HDRS) and Hamilton anxiety rating scale (HARS)] and health-related quality of life (EQ-5D). Other variables will be clinical and socio-demographic. Intervention will consist of 17 psychoeducation sessions for the intervention group and information on suicide for the control group. </p><p><strong>Conclusions:</strong> This project aims to assess the effectiveness of a psycho-educational intervention on reducing the number of suicidal behaviours in the prison environment. If positive, the prison community will have a new tool to curb suicide in prisons.</p><p><strong>Trial registration:</strong> The trial was registered on clinicalTrials.gov on 19 January 2022 (NCT05195554).</p>
