How this service works
Rockwood 2005 CSHA Clinical Frailty Scale 1-7 as assigned by the caller (Box 1). Returns cfs, score, max 7, and the published label. Does not implement the later 9-point CFS (8 very severely frail, 9 terminally ill) or CFS 2.0 label changes. Not a diagnosis; magent does not examine the patient.
Output
Returns a JSON object containing the input CFS integer, the numeric score, the maximum possible score (7), and the published Rockwood 2005 CSHA label string (e.g. 'Mildly Frail'). Does not include 9-point CFS entries or CFS 2.0 label revisions.
Example use cases
Geriatric triage score labeling
“My patient was assigned a CFS score of 6 — can you look up the official Rockwood 2005 label for that frailty level?”
EHR frailty documentation enrichment
“I have a list of CFS integers from our geriatric assessments; start with CFS 3 and give me the published CSHA label so I can populate our EHR notes.”
Clinical decision support display
“For our surgical pre-op dashboard, look up the Rockwood 2005 frailty description for CFS 4 so we can display it alongside the score.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/cfsWhen to prefer
Use this endpoint when you need to resolve a Rockwood 2005 7-point CFS integer to its official published label in a clinical or documentation workflow. Prefer it over manual lookup tables to ensure consistent, authoritative labeling. Not appropriate for the 9-point CFS or CFS 2.0 label variants.
Side effects
- CFS value outside 1–7 returns an error (8 and 9 from the later 9-point scale are not accepted)
- Non-integer or missing cfs query parameter causes a validation error
- Payment failure (x402) if USDC payment is not completed
