Summary

This summary is machine-generated.

Western Lapland, Finland has a higher suicide rate, particularly among older men using firearms with low service contact. This elevated risk is not linked to Open Dialogue (OD) service users.

Area Of Science

  • Psychiatry
  • Public Health
  • Epidemiology

Background

  • Suicide rates in Finland exhibit regional disparities, with Western Lapland (WL) identified as a high-risk area.
  • Western Lapland is recognized for pioneering Open Dialogue (OD)-based psychiatric services, a unique approach to mental healthcare.
  • Understanding the specific characteristics of suicide cases in WL is crucial for developing targeted prevention strategies.

Purpose Of The Study

  • To compare demographic and clinical characteristics of suicide cases in Western Lapland (WL) with the rest of Finland.
  • To investigate potential links between the elevated suicide rate in WL and the region's specific population or service characteristics.
  • To assess whether the Open Dialogue (OD) service model influences suicide case profiles.

Main Methods

  • Utilized register-based data encompassing all suicides (n=4502) in Finland between 2017 and 2022.
  • Applied Principal Component Analysis for dimensionality reduction, followed by K-means clustering to identify distinct suicide case profiles.
  • Employed logistic regression to analyze the association between the WL region and identified clusters.

Main Results

  • Western Lapland (WL) recorded a higher average annual suicide rate (18 per 100,000) compared to the rest of Finland (13.5 per 100,000).
  • Five distinct clusters of suicide cases were identified nationally, including profiles of younger men with low service use, individuals with repeated attempts, socially integrated men, older men with low service use, and those treated for severe mental disorders.
  • Suicides in WL were significantly more likely to fall into the cluster of older men with low service contact, often involving firearm use (OR: 2, 95%CI: 1.2-3.3).

Conclusions

  • The higher suicide rate in Western Lapland is associated with older men exhibiting low service contact and utilizing firearms, necessitating tailored suicide prevention efforts.
  • The study found no evidence suggesting that the region's elevated suicide rate is attributable to a higher incidence of suicides among users of Open Dialogue (OD) psychiatric services.
  • Findings underscore the importance of regional-specific analyses and interventions in suicide prevention, independent of specific service models like OD.
