Barthel Index
Barthel Index measures the level of disability or dependence of an individual in ten instrumental activities of daily living (mobility, using stairs, dressing, bathing, grooming, feeding, transfer, toileting and bladder and bowel continence) 1. The Barthel Index was developed as a measure to assess disability in patients with neuromuscular and musculoskeletal conditions receiving inpatient rehabilitation 2. The original Barthel Index was scored in steps of five points to give a maximum total score of 100. A widely adopted modified form of Barthel Index by Collin and Wade 3 includes a revised score range of 0–20. Lower Barthel Index scores indicated poorer physical function 4.
Guidelines for use of the Barthel Index are as follows 5:
- Barthel Index should be used as a record of what a patient does, not as a record of what a patient could do.
- The main goal is to establish degree of independence from any help, physical or verbal, however minor and for whatever reason.
- The need for supervision renders the patient not independent.
- A patient’s performance should be established using the best available evidence. The patient, friends/relatives, and nurses are usually asked for the information gathered, but direct observation and common sense are also important. However, direct testing is not needed.
- Usually, the patient’s performance over the preceding 24-48 hours is important, but longer periods are occasionally relevant.
- Middle categories imply that the patient supplies over 50% of the effort.
- Use of aids to be independent is allowed.
Barthel Index key points
- The reliability of the Barthel Index has been investigated in the major clinical settings relevant to older people.
- The Barthel Index was found to be reliable when administered by face-to-face interview and by telephone and on testing by different observers, but has a considerable imprecision.
- The individual studies address different aspects of reliability and use various different statistics, limiting comparability.
- Test–retest reliability has not been investigated on older people with multiple diagnoses.
- A large repeatability study on patients with multiple diagnoses is required to investigate the inter-observer disagreement demonstrated with the Bland and Altman method and to clarify the importance of assessor training.
