Suicide Data in Trauma Centers: Implications of Imprecision

Area of Science:

• Trauma care research
• Injury surveillance systems
• Public health data accuracy

Background:

• Trauma registries are vital for evaluating patient care quality and informing research.
• Data from registries support outreach, planning, and improving trauma patient outcomes.
• The accuracy of suicide-related data within trauma registries remains understudied.

Purpose of the Study:

• To assess the precision of trauma registry coding for self-inflicted injuries.
• To determine the accuracy of labeling injuries as suicide attempts in a Level I trauma center.
• To evaluate coding practices for patients presenting after self-inflicted injuries.

Main Methods:

• Retrospective cohort analysis of a Level I trauma center's registry data (2011-2021).
• Inclusion of all patients presenting with self-inflicted injuries.
• Manual chart review to identify miscategorized cases lacking suicidal intent.

Main Results:

• 537 patients with self-inflicted injuries were identified over 11 years.
• 16% of these patients were misclassified as suicide attempts.
• Misclassified injuries included accidents and nonsuicidal self-harm.

Conclusions:

• A significant 16% of trauma registry patients were overcategorized as suicide attempts.
• Inaccurate coding of self-inflicted injuries can misrepresent injury patterns and causes.
• Imprecise data may lead to ineffective injury prevention and suicide prevention programs.
