How this service works
Katz 1963 Index of Independence in Activities of Daily Living: six caller-assigned independence flags (bathing, dressing, toileting, transferring, continence, feeding). Each independent function scores 1; max 6. magent sums the published 0–6 count and does not observe the patient. Not the Barthel Index, not Katz letter grades A–G, and not a rehab order or placement decision. Not a medical device.
Output
Returns a numeric Katz ADL total score from 0 to 6, where each of the six independence flags (bathing, dressing, toileting, transferring, continence, feeding) contributes 1 point if true and 0 if false. The endpoint sums the caller-supplied values only; it does not observe or evaluate the patient.
Example use cases
Geriatric discharge planning ADL screen
“I need to score an elderly patient before discharge: they can bathe and dress themselves, but they can't toilet independently, can't transfer without help, are incontinent, and need help feeding. What's their Katz ADL score?”
Long-term care eligibility documentation
“For our nursing home intake form, calculate the Katz index for a resident who is independent in all six ADL categories — bathing, dressing, toileting, transferring, continence, and feeding.”
Research cohort functional status baseline
“I'm building a dataset and need to compute Katz ADL scores for study participants. This participant is independent in bathing, dressing, continence, and feeding, but dependent in toileting and transferring — what's the score?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/katzWhen to prefer
Use this endpoint when you need a fast, reproducible computation of the published Katz 1963 ADL 0–6 integer score from six already-assessed boolean independence flags. Prefer it over manual summation in automated pipelines, EHR integrations, or research workflows where consistent scoring logic matters. Do not use it as a substitute for clinical assessment, as a Barthel Index calculator, as a Katz letter-grade (A–G) classifier, or as input to a placement or rehabilitation decision — those are distinct clinical functions.
Side effects
- Missing required boolean flags — returns validation error if any of the six query parameters are absent
- Non-boolean values passed for flags — schema validation failure
- Payment failure via x402 — 402 response if USDC payment is not processed
- Network timeout — transient 5xx if the API is unreachable
