The structure of the Early Rehabilitation Barthel Index (ERBI) should be modified: evidence from a Rasch analysis study.

PMID 37534887WHAT IT FOUND
The Early Rehabilitation Barthel Index fails to accurately measure functional changes in patients with severe acquired brain injury.
Most patients scored at the lowest possible level, meaning the test cannot distinguish between different degrees of impairment or track recovery in this population.
Key findings
01The total score of the Early Rehabilitation Barthel Index is not a valid measure of functional changes for patients with severe acquired brain injury in early rehabilitation.
02Nearly half of the patients scored at the lowest possible level, indicating the scale cannot discriminate between patients at the lower end of functional ability.
03Items assessing confusional state and behavioral disturbances did not fit the measurement model because their scoring structure did not match how these symptoms change as patients recover.

What it does not show
The findings cannot be generalized to patients with other diseases or those in settings like the Intensive Care Unit. The analysis was a secondary use of data from previous studies, so the researchers could not control how the ERBI was administered or check for inter-rater reliability. The proposed fix for the confusion and behavior items was based on simulated data, not new real-world testing. The sample was limited to Italian patients with severe acquired brain injury in early rehabilitation.
Declared interests
The authors declared no conflicts of interest. The publication was supported by funding from the Italian Ministry of Health.
The easy way to misread this
Do not assume the Early Rehabilitation Barthel Index is valid simply because it is widely used. This study shows it fails to measure functional changes in severe acquired brain injury because most patients score at the absolute bottom, making it impossible to track recovery or distinguish between patients.
