How this service works
FeverPAIN from Little 2013 (PRISM): five caller-assigned flags (fever in past 24 hours, purulent tonsils, attendance within 3 days, severely inflamed tonsils, no cough or coryza), 1 point each, max 5. Returns published score groups 0-1 / 2-3 / 4-5. Deterministic published score with citation; not a medical device, not a test-or-treat order, and not a diagnosis of streptococcal pharyngitis. magent does not examine the throat.
Output
Returns the integer FeverPAIN total score (0–5), the published score group (0–1, 2–3, or 4–5) as defined by Little 2013, and a citation. Does not include a diagnosis, a treatment recommendation, or a test-or-treat order.
Example use cases
Antibiotic stewardship in urgent care
“My patient has a sore throat with fever in the last 24 hours, purulent tonsils, presented within 3 days, severely inflamed tonsils, and no cough or runny nose — can you calculate the FeverPAIN score and tell me which score group they fall into?”
Remote triage documentation
“I'm documenting a telehealth consult: the patient reports fever yesterday, no cough, no runny nose, attended today which is day 2 of symptoms, but I can't assess tonsils visually so I'll mark purulent tonsils and severe inflammation as false — what is the FeverPAIN score and group?”
Clinical audit data pipeline
“For this batch of sore throat cases I need to compute FeverPAIN scores — start with case 1: fever in past 24h yes, purulent tonsils no, attendance within 3 days yes, severely inflamed tonsils no, no cough or coryza yes. What score and group does that give?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/feverpainWhen to prefer
Use this endpoint when you need a deterministic, citation-backed computation of the FeverPAIN score exactly as published by Little 2013, with auditable score-group output, rather than approximating the arithmetic locally. Prefer it in workflows requiring reproducible clinical scoring with a traceable source reference.
Side effects
- Missing any of the five required boolean query parameters returns a validation error
- Non-boolean values for flag parameters cause a schema error
- Network timeout or 402 payment required if x402 payment header is absent or insufficient
