How this service works
Watanabe 2011 ESAS-r from nine caller-assigned integers 0-10 (pain, tiredness, drowsiness, nausea, lack of appetite, shortness of breath, depression, anxiety, wellbeing; now; 0 none/best, 10 worst). magent does not administer the form. Sum 0-90. Watanabe 2011 published no severity classes for that sum. Not Bruera 1991 ESAS, not ESAS-r Renal (itch is not a core item), not a diagnosis or treatment order, and not a medical device.
Output
Returns the ESAS-r (Watanabe 2011) total sum score as an integer between 0 and 90, representing the arithmetic sum of the nine caller-provided symptom ratings. No severity classification is returned, as Watanabe 2011 published no severity banding for the aggregate sum.
Example use cases
Palliative care symptom burden tracking
“I need to compute the ESAS-r total for my patient who just rated their symptoms: pain 8, tiredness 6, drowsiness 5, nausea 3, lack of appetite 7, shortness of breath 4, depression 5, anxiety 6, wellbeing 7 — can you get that sum for me?”
Oncology clinic symptom audit
“A cancer patient completed the ESAS-r and scored: pain 2, tiredness 4, drowsiness 1, nausea 0, lack of appetite 3, shortness of breath 1, depression 2, anxiety 3, wellbeing 2 — what is their total ESAS-r score using the Watanabe 2011 version?”
Research data pipeline scoring
“I have ESAS-r responses from a study participant — pain 5, tiredness 5, drowsiness 5, nausea 5, lack of appetite 5, shortness of breath 5, depression 5, anxiety 5, wellbeing 5 — please calculate their aggregate score.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/esas_rWhen to prefer
Use this endpoint when you need a fast, accurate arithmetic sum of the nine Watanabe 2011 ESAS-r symptom items and already have the caller-assigned integer scores in hand. Prefer it over manual summation to avoid arithmetic errors in automated pipelines. Do not use it if you need ESAS (Bruera 1991), ESAS-r Renal (which includes itch), severity class labels, or any form administration — this endpoint only computes the sum from pre-collected scores.
Side effects
- Missing one or more of the nine required query parameters — returns a validation error
- Non-integer or out-of-range (outside 0–10) values for any symptom parameter — returns a validation error
- Payment failure or insufficient USDC balance for the x402 micropayment — request rejected before computation
- Network timeout or server unavailability — no result returned
