Outpatient Mental Health Nurses' Experiences of Suicide Follow-Up Interventions: A Qualitative Interview Study

INTRODUCTION

Suicide is a leading cause of death worldwide. Following a suicide attempt, many patients receive suicide follow-up interventions (SFI) from outpatient mental health care services, where outpatient mental health nurses play a crucial role. There is an urgent need to raise awareness of improvements and opportunities for development in this aspect of care to gain insights into potential areas for improvement and opportunities for development.

AIM

To investigate outpatient mental health nurses' experiences of SFI.

METHOD

A qualitative interview study was conducted with 10 outpatient mental health nurses. Conventional content analysis was used to analyse the data.

RESULTS

Three categories emerged: connecting with and understanding suicidal patients, being dependent on adequate conditions for SFI, and feeling competent but vulnerable in SFI.

DISCUSSION

Providing structured training for nurses to address patients with particularly challenging conditions is vital, as SFI entails complex and challenging situations. Training that incorporates proven methods from other interventions, involving the expertise of those with lived experience, employers, and academics, can offer significant advantages. Promoting increased collaboration can enhance the safety of assessments.

IMPLICATIONS FOR PRACTICE

Team-based SFI can enhance suicide follow-up intervention services in psychiatric outpatient care.

Effectiveness of a French Program to Prevent Suicide Reattempt (VigilanS)

AIM

Brief contact interventions (such as letters, green cards, telephone calls or postcards) for reducing suicide reattempt (SR) and suicide have been evaluated since the 1980s, but results have been inconsistent. VigilanS is one of these programs that has benefited patients hospitalized for suicide attempt (SA) after discharge in 2 departments of northern France since 2015. The purpose of this study is to demonstrate its effectiveness in reducing SR.

METHODS

Patients exposed to VigilanS in 2016 were recruited from the medical administrative database of the program, and the nonexposed patients from a database of the medico-surgical ward outside the scope of the program. First, a Cox model was used to compare the probability of SR during the 12-month follow-up period between the 2 groups. Second, a propensity score using the variables sex, age, source, SA history and SA method was used to match the VigilanS-exposed and the nonexposed patients. A Cox model propensity score adjusted analysis was reiterated on the matched data.

RESULTS

The exposed and nonexposed groups included 3,068 and 3,694 individuals, respectively. In the bivariate analyses, the cumulative probability of SR at 12 months was significantly lower in the exposed group (6.0%, 95% confidence interval (CI): 5.5-6.5%) than in the nonexposed group (16.8%, 95% CI: 15.9-17.7%; p < 0.001). In the Cox model, the hazard ratio of SR was 0.38 in the exposed patients (95% CI: 0.36-0.40, p < 0.001). After matching, the cumulative probability of SR at 12 months was 5.2% in exposed versus 22.2% in nonexposed patients (p < 0.001). In the propensity score-adjusted Cox model, the hazard ratio of SR in the exposed patients was 0.19 (95% CI: 0.14-0.24, p < 0.001).

CONCLUSION

The results suggest the effectiveness of this real-life program for reducing SR. However, VigilanS only benefits a portion of the patients hospitalized for SA and therefore could be extended.

Effectiveness of suicide prevention interventions: A systematic review and meta-analysis

OBJECTIVE

This study provides an estimate of the effect size of suicide prevention interventions and evaluates the possible synergistic effects of multilevel interventions.

METHOD

A systematic review and meta-analysis were conducted of controlled studies evaluating suicide prevention interventions versus control published between 2011 and 2017 in PubMed, PsycINFO, and Cochrane databases. Data extraction and risk of bias assessment according to ROBINS criteria were performed by independent assessors. Cohen's delta was calculated by a random meta-analysis on completed and attempted suicides as outcomes. Meta-regression explored a possible synergistic effect in multilevel interventions. PROSPERO ID number: CRD42018094373.

RESULTS

The search yielded 16 controlled studies with a total of 252,932 participants. The meta-analysis was performed in 15 studies with 29,071 participants. A significant effect was found for suicide prevention interventions on completed suicides (d = -0.535, 95% CI -0.898; -0.171, p = .004) and on suicide attempts (d = -0.449, 95% CI -0.618; -0.280, p < .001). Regarding the synergistic effect of multilevel interventions, meta-regression showed a significantly higher effect related to the number of levels of the intervention (p = .032).

CONCLUSIONS

Suicide prevention interventions are effective in preventing completed and attempted suicides and should be widely implemented. Further research should focus on multilevel interventions due to their greater effects and synergistic potential. Further research is also needed into risk appraisal for completed versus attempted suicide, as the preferred intervention strategy differs with regard to both outcomes.
