lethality assessment
Systematic evaluation of suicide risk factors to determine the likelihood and immediacy of self-harm potential.
Full Definition
Lethality assessment is a structured clinical evaluation process designed to identify and quantify suicide risk factors to determine the probability and timeline of potential self-harm. This assessment typically examines current suicidal ideation, specific plans and means, previous attempts, protective factors, mental status, substance use, and psychosocial stressors. Clinicians use various standardized tools and clinical judgment to categorize risk levels (low, moderate, high, imminent) and determine appropriate interventions and level of care. Documentation of lethality assessment is crucial for treatment planning, safety planning, and legal protection, and should be updated regularly as clinical status changes.
Usage
Usage note: Document specific risk factors, protective factors, and risk level determination with clear rationale for clinical and legal purposes.
