SI

Full Definition

Suicidal Ideation (SI) encompasses the spectrum of thoughts, ideas, wishes, or plans related to ending one's own life. In psychiatric documentation, SI is classified by severity and specificity, ranging from passive thoughts of death to active plans with specific methods and timeline. Clinical assessment of SI includes evaluating the presence of protective factors, access to means, intent, and plan specificity. Documentation must be precise and thorough, as SI assessment directly impacts treatment planning, level of care decisions, and legal obligations for patient safety. The term is fundamental to risk assessment and safety planning in psychiatric settings.

Usage

Usage note: Always define the acronym on first use in clinical documentation; distinguish between passive and active SI in assessments.
