LOCUS
Pronunciation: LOH-kus
Also written as: LOCUS — Level of Care Utilization System
Acronym for Level of Care Utilization System, a standardized assessment tool used to determine the appropriate level of mental health treatment for adults.
Full Definition
The Level of Care Utilization System (LOCUS) is a validated instrument developed by the American Association of Community Psychiatrists (AACP) to guide clinicians and reviewers in matching adult patients to appropriate levels of psychiatric and addiction treatment. It scores six dimensions—risk of harm, functional status, medical needs, recovery environment, treatment and recovery history, and engagement—to produce a composite score mapped to a recommended level of care. Editors will encounter LOCUS scores and subscale ratings in utilisation review documents and insurance prior-authorization submissions. It should always be fully capitalised as an acronym and not confused with the Latin word 'locus' in neurological or genetic contexts.
Usage
Usage note: Always fully capitalised. Expand on first use. Do not confuse with the neurological/genetic term 'locus' (italicised, lowercase in scientific writing).
