Safety Planning Intervention in Swedish Healthcare: A Multisite Study for Suicide Prevention

Suicide is one of the leading causes of premature death and a prioritized public health concern. Safety Planning Intervention (SPI) is a method with strong international research support for reducing suicidal behaviour by enhancing individuals' strategies for crisis management and improving access to support. SPI is a single-session intervention lasting approximately 45 minutes, which any healthcare provider can deliver after a brief training. Despite promising results, the implementation of SPI in Swedish healthcare remains limited. This project examines how SPI can be integrated into various healthcare settings and evaluates its impact on suicide-related emergency visits, psychiatric hospitalizations, and healthcare utilization. Data and Methods Stepped-Wedge implementation study in specialist psychiatry, where SPI is gradually introduced in psychiatric units. This study design allows for a robust evaluation of effects while ensuring all units eventually receive the intervention. As part of this study, a survey among healthcare professionals will be conducted to assess their experiences with feasibility, usability, and implementation barriers. Data will be collected from QlikView healthcare utilization data. Poisson regression models with mixed effects will be used to analyze the impact of SPI on emergency visits and psychiatric hospitalizations. A health economic analysis will be conducted to evaluate the cost-effectiveness of SPI. Societal Relevance and Impact The project contributes to Sweden's national suicide prevention strategy by: 1. Scientifically evaluating the feasibility and effects of SPI in Swedish healthcare. 2. Developing training programs for healthcare professionals in suicide prevention. 3. Informing policy decisions and national guidelines. 4. Analyzing the cost-effectiveness of SPI from a societal perspective. Implementation The research team includes experts in suicide prevention, psychiatry, epidemiology, patient safety, and health economics, creating a strong multidisciplinary foundation. The Stepped-Wedge design ensures an ethically and methodologically sound evaluation of SPI. Gradual implementation allows for time-based comparisons, minimizes selection bias, and ensures all patients receive the intervention. The project is conducted in close collaboration with healthcare providers and policymakers to ensure that research findings can be integrated into clinical practice and strengthen suicide prevention efforts in Sweden.
