Domain of Occupational Therapy Practice The Multidisciplinary Team Patient and Caregiver Adopted from: Center on Human Development and Disability, Clinical Training Unit, University of Washington Common Evaluation Tools Barthel Index (BI) Functional Independence Measure (FIM) Mini Mental State Examination (MMSE) Functional Need Assessment (FNA) Barthel Index BI First published in 1965 by Mahoney F & Barthel D Purpose Measure performance in basic Activities of Daily Living (ADL) Establish degree of independence from any help Monitor improvement in ADL over time Populations tested Stroke, neurological disorders, geriatrics, brain injury Assess 10 ADL /functional mobility activities feeding, bathing, grooming, dressing, bowels, bladder, toilet use, bed/chair transfers, mobility on level surfaces and stairs Scoring original score 0-100 modified by Granger et al in 1979 (0-100) and further refined by Collin et al, 1988 (0-20) and Shah et al in 1989 Basically, the higher the score the more independent the person; 0 (totally dependent) to 100 (completely independent) Interpretation (Sinoff and Ore, 1997) 80-100, independent 60-79, needs minimal help with ADL 40-59, partially dependent 20-39, very dependent <20, totally dependent Barthel Index Form 2
Functional Independence Measure FIM Introduced in 1986 as BI was considered too simple and unresponsive Purpose Measure functional independence in personal activities of daily living (13 items) and measures of communication and social cognition (5 items) Useful for assessment of progress, usually assessed during admission and pre-discharge Populations tested Stroke, spinal cord injury, brain injury, multiple sclerosis, orthopedic conditions, geriatrics Comprises 18 items 13 motor tasks : eating, grooming, bathing, upper body dressing, lower body dressing, toileting, bladder management, bowel management, bed to chair transfer, toilet transfer, shower transfer, locomotion, stairs and 5 cognitive tasks : cognitive comprehension, expression, social interaction, problem solving, memory Scoring 7-point ordinal scale for each task that ranges from complete dependence (1) to complete independence (7) Interpretation Scores range from 18 (lowest) to 126 (highest) Admission FIM >70 associated with achieving non-dependence by discharge whereas admission score < 50 remained dependent (Ween et al, 2000) Functional Independence Measure Form Mini-Mental Mental State Examination MMSE Introduced by Folstein et al in 1975 Purpose Used to screen for cognitive impairment Commonly used to screen for dementia Also used to estimate the severity of cognitive changes in an individual over time Populations tested Used to assess cognitive impairment in various populations Consists of 11 simple questions or tasks grouped into 7 cognitive domains Orientation to time, orientation to place, registration of 3 words, attention and calculation, recall of 3 words, language use, and visual construction (comprehension and basic motor skills) Scoring Direct observation of completion of test items/ tasks Interpretation A score of < 24 (maxi 30) is generally accepted cutoff indicating the presence of cognitive impairment (Dick et al, 1984) Consideration of age and education 27-30: normal 21-26: mild cognitive impairment 11-20: moderated cognitive impairment 0-10: severe 3
MMSE Form Functional Need Assessment CFNA Published in 1990 by S.B. Dombrowski, M. Kane, N.B. Tuttle and W. Kincaid Purpose Measure patient s ability to initiate and perform basic Activities of Daily Living (ADL) Populations tested people with chronic mental illness 26-item performance-based measure instrument covers multiple areas of adaptive functioning (subscales) such as personal hygiene or kitchen skills Each subscale further comprises of five items in a developmental sequence E.g. the personal hygiene subscale consists of 5 items which are arranged in the order from the most primitive task (identify or demonstrate use of implements for personal hygiene) to the most complex task (independent in personal hygiene) Scoring A person will receive a score of 5 for each of the items he or she successfully performs, or a score of 0 for failing to perform any item under a subscale Maxi score 5x5x26 The total score is then converted into an average score by dividing it by 26 Basically, the higher the score the better the functioning Interpretation (Law, 1999) The recommended cut-off scores for the independent living, halfway house, and long stay care home groups were 605/610-650, 550/555-605/610, and 450/455-550/555 respectively Functional Need Assessment Form ADL Training Occupational Therapy Interventions 4
