x402
CAM-ICU Delirium Screener (Ely 2001) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Applies the CAM-ICU algorithm to four caller-supplied feature flags and returns whether delirium is present or absent.

How this service works
CAM-ICU (Ely 2001). Delirium is present iff Feature 1 (acute onset or fluctuating course) and Feature 2 (inattention) both hold, and Feature 3 (disorganized thinking) or Feature 4 (altered level of consciousness) also holds. The caller assigns each feature as already determined. magent does not observe the patient, administer RASS, or run the attention screening exam. Not a diagnosis and not a medical device.
Output
A Boolean or categorical determination of whether the CAM-ICU criteria are met (delirium present or absent), derived from the logical combination: (Feature 1 AND Feature 2) AND (Feature 3 OR Feature 4).
Example use cases
ICU nurse delirium flag workflow
“I've assessed my ventilated patient: they had a fluctuating mental status today (Feature 1 true), failed the attention screening (Feature 2 true), answered the thinking questions correctly (Feature 3 false), and is on a RASS of 0 (Feature 4 false) — is CAM-ICU positive?”
Clinical documentation assistant
“For the chart note, the patient has acute onset mental status change and inattention, plus disorganized thinking, but no altered level of consciousness — compute the CAM-ICU result so I can document it.”
Automated delirium surveillance agent
“I've collected the four CAM-ICU features for bed 12: acute onset true, inattention true, disorganized thinking true, altered consciousness false — what does the CAM-ICU algorithm say?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/cam_icuWhen to prefer
Use this endpoint when you have already assessed and assigned the four CAM-ICU features independently (e.g., via clinical observation, RASS administration, and attention exam) and need to apply the Ely 2001 logical algorithm to produce a positive/negative result. This endpoint does not perform the clinical assessment itself — it only applies the decision logic. Prefer it for automating documentation pipelines, audit trails, or clinical decision-support agents where the feature flags are already determined.
Side effects
- Missing required feature flags returns a validation error
- Invalid boolean values for any feature parameter cause a bad request
- Network timeout if the endpoint is temporarily unavailable
