Duty to Warn
A legal and ethical obligation for mental health clinicians to take reasonable steps to protect identifiable third parties from serious harm threatened by a patient.
Full Definition
The duty to warn arises from the landmark California Supreme Court case Tarasoff v. Regents of the University of California (1976), which established that mental health professionals may be obligated to warn identifiable potential victims of serious threats made by their patients. In emergency psychiatry documentation, the duty to warn is frequently referenced in risk assessment notes, discharge summaries, and consultation records where a patient has expressed specific homicidal ideation. Editors should note that the legal scope of duty-to-warn statutes varies significantly by jurisdiction and should not edit content in ways that alter its legal meaning without clinical review. The related but distinct concept is 'duty to protect,' which may be satisfied through means other than direct warning.
Usage
Usage note: Do not use 'duty to warn' and 'duty to protect' as synonyms. In some jurisdictions only 'duty to protect' is legally recognised. Flag jurisdiction-specific differences when editing policy documents.
