Interventions to reduce suicides at suicide hotspots: a systematic review

Area of Science:

• Public Health
• Suicidology
• Intervention Science

Background:

• Suicide hotspots are locations like bridges, cliffs, and railway tracks that facilitate suicide due to accessibility or seclusion.
• These sites present unique challenges for suicide prevention efforts.

Purpose of the Study:

• To identify and evaluate interventions aimed at reducing suicides at identified hotspots.
• To assess the effectiveness of various suicide prevention strategies in these specific environments.

Main Methods:

• A comprehensive literature search was conducted using the Medline database.
• Studies were selected based on their relevance to interventions for suicide reduction at hotspots.

Main Results:

• Four primary intervention approaches were identified: restricting access to means (e.g., barriers), encouraging help-seeking (e.g., signs, phones), increasing third-party intervention (e.g., surveillance), and promoting responsible media reporting.
• Strong evidence supports restricting access to means as an effective method to prevent suicides at hotspots without causing substitution effects.
• Evidence for other methods is less robust but indicates potential effectiveness.

Conclusions:

• Further well-designed research is necessary to strengthen the evidence base for suicide prevention interventions at hotspots.
• Continued investigation into the efficacy of various strategies is crucial for developing effective public health policies.
