Barthel Index Calculator

Barthel Index Calculator for Geriatrics. A total of 100 does not establish that every skill needed to live alone is intact. Review individual activities and the person's environment rather than inferring discharge suitability from a band.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

The classic form uses a 0-100 total with higher scores indicating greater independence in scored basic activities. The source form and rights notice are available at https://www.sralab.org/sites/default/files/2017-07/barthel.pdf.

When to use this calculator

Discuss rehabilitation progress or care needs after an authorized functional assessment. Use actual performance, not an assumption about what someone might manage in ideal conditions.

Inputs used

  • Final classic 0-100 Barthel total in steps of 5
  • Assessment date, setting and source version

Clinical interpretation

A total of 100 does not establish that every skill needed to live alone is intact. Review individual activities and the person's environment rather than inferring discharge suitability from a band.

Worked example

A comparable score rising from 55 to 70 increases by 15 points. The number alone does not show which support needs changed. A value of 73 is rejected for this classic version; it may belong to a modified form and needs version checking.

Limitations and safety notes

The 0-20 form and modified Barthel variants are not interchangeable with this input. The copyright notice requires permission for commercial instrument use; no form or descriptors are reproduced here and no license is granted.

Frequently asked questions

Should a 0-20 result simply be entered here?

No. The page expects the stated classic 0-100 version. Confirm the actual instrument and authorized conversion before comparing versions.
