Lethality of Suicide Attempt Rating Scale (LSARS) III
Clinically oriented assessment tool with strict separation between manuscript-derived deterministic lookup and app-layer contextual interpretation.
Medical lethality estimate only. This does not directly measure suicidal intent and does not replace clinical judgment.
LSARS anchor scale (medical lethality + rescue context)
Lower anchors generally indicate lower immediate medical lethality; higher anchors indicate greater likelihood of death without rescue/intervention.
Death is an impossible result of the suicidal behavior.
Death is very highly improbable.
Death is improbable and would occur due to unforeseen secondary effects.
Death is improbable as long as the patient or another agent administers first aid. The patient performs the act publicly or directly communicates their actions to others.
Life and death are equally likely outcomes. This rating is also chosen when the details of the attempt are vague or incomplete.
Death is the likely outcome without immediate and significant first aid. The act must also involve communicating the actions to others and/or performing the act publicly such that they are likely to be helped or found.
Death is likely to be outcome unless the patient is saved by another agent. The patient does not communicate their actions to others and/or their actions are taken in private.
Death is likely to be the outcome unless the patient is saved by chance intervention. No communication is made, and/or effort is made to prevent others from intervening.
Death is a near certainty regardless of intervention.

LSARS-III Assessor clinical summary Method: Ingestion / pharmaceutical overdose Source type: Manuscript Table 2 Primary lethality impression: No deterministic manuscript table lookup for this method Weight: not entered Substance: not selected Strength: not selected Quantity: 0 tablets/capsules/units Amount certainty: exact Deterministic LD50 Category: not available Estimated contextual LSARS range: Need deterministic category first Contextual modifier: Circumstances suggest intermediate rescue likelihood Bottom line: medical lethality estimate only; does not directly measure intent; does not replace clinical judgment.
Ingestion lethality estimate
Estimated medical lethality from method data and manuscript table lookup when available.
Primary lethality label
No deterministic manuscript table lookup for this method
Use anchor-informed app estimate and contextual interpretation for this method.
Method: Ingestion / pharmaceutical overdose
Mapped weight band: Not mapped
Substance: Not selected
Strength: Not selected
Quantity: 0 units
Show manuscript lookup details
Deterministic manuscript lookup requires mapped weight band, substance, and manuscript-listed strength.
Table 2 note: Note: Patients with a history of abuse/chronic use will be able to tolerate higher doses **Co-ingestion of ethanol increases toxicity significantly.
Effect of circumstances on likely rescue
Separate app-layer interpretation; does not change deterministic manuscript category.
Estimated contextual LSARS range: Need deterministic category first
Select weight, substance, and manuscript-listed strength to establish deterministic toxicity category before contextual interpretation.
