Everyday barthel index problems come down to one relationship between bathing, bladder control, bowel control, dressing, feeding, grooming, mobility, stairs, toilet use and transfers. This calculator turns those numbers into barthel score, with the working shown so you can check the result rather than simply trust it.
What Is the Barthel Index Calculator?
The barthel index calculator gives you an estimate of barthel score based on bathing, bladder control, bowel control, dressing, feeding, grooming, mobility, stairs, toilet use and transfers.
It is a quick reference figure rather than a diagnosis, and it is most useful for tracking how a number moves over time rather than for interpreting a single reading.
How the Barthel Index Estimate Is Worked Out
The calculation follows published reference relationships, so it is a reasonable approximation when the inputs are accurate. It assumes an average adult and does not account for individual variation.
If you are comparing two people, or the same person over a period of weeks, keep the method and the inputs identical. A change in the method can easily look like a change in the person.
What This Calculator Does Not Do
It does not diagnose anything, and it does not replace advice from a clinician. If a figure comes out at an extreme, or if it differs sharply from what you expect, that is a reason to speak to a professional rather than to adjust the inputs.
Nothing you type here is stored or sent anywhere. The whole calculation happens in your browser.
A Worked Example
Working through an example, with bathing set to 0, bladder control set to 0, bowel control set to 0, the calculator returns barthel score of 0. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out barthel score?
Enter bathing, bladder control, bowel control, dressing, feeding, grooming, mobility, stairs, toilet use and transfers. The calculator then works through the relationship and reports barthel score.
What does the barthel index actually calculate?
It takes bathing, bladder control, bowel control, dressing, feeding, grooming, mobility, stairs, toilet use and transfers and converts them into barthel score using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter bathing?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
Why does a small change in one value move the answer so much?
That happens when an output depends on a ratio, because dividing by a small number magnifies any change in it. Check the units first, then check whether the value you entered is in the range the relationship was designed for.
