Premorbid Function
The level of physical and cognitive functional ability a patient maintained prior to the acute illness or injury that prompted the current rehabilitation admission.
Full Definition
Premorbid function is a cornerstone reference point in geriatric rehabilitation, establishing the realistic ceiling for recovery and informing individualised goal-setting. It is typically ascertained through structured interview with the patient, family members, or carers, and captured in admission documentation such as a therapy initial assessment or geriatric assessment summary. Editors should be aware that the hyphenated form 'pre-morbid' appears in older literature but the unhyphenated 'premorbid' is now preferred in most contemporary clinical style guides. Conflation with 'baseline function' is common but erroneous, as baseline may refer to the state on admission, which may already be acutely impaired.
Usage
Usage note: Prefer unhyphenated 'premorbid' in contemporary clinical documents. Always distinguish from 'baseline function', which refers to the state on admission.
