What it computes
Compute the Weiss 2014 CEDOCS reduced-model score from caller-supplied critical-care patients, longest admitted-patient hours since admission, waiting-room count, ED patients, ED beds, and annual ED visits.
When to use
When an agent has the published snapshot counts, hours, and annual visits for a community ED and needs the Weiss 2014 reduced-model CEDOCS score, not a diversion or ambulance-bypass order.
When not to use
- Not a medical device. Not a diversion or ambulance-bypass order.
- magent does not count patients, beds, or wait times. Caller supplies the published numeric inputs.
- Weiss 2014 reduced model for community EDs. Academic NEDOCS is a different tool.
- The paper's outcome scale is 0-100. magent does not clamp the linear combination, does not double the score onto a 0-200 range, and does not invent 20/60/100 named class bands.
- Pediatric-only EDs were not this model. Not a diagnosis of crowding-related harm.
Formula
cedocs_score = -30.39 + 3.00 * critical_care_patients + 0.53 * admit_time_hours + 1.16 * waiting_room_patients + 20.66 * (ed_patients / ed_beds) + 0.00126 * ed_visits_per_year - 1.11e-12 * pmax(ed_visits_per_year - 18811, 0)^3 + 8.23e-12 * pmax(ed_visits_per_year - 43012, 0)^3 - 8.20e-12 * pmax(ed_visits_per_year - 49466, 0)^3 + 1.08e-12 * pmax(ed_visits_per_year - 67273, 0)^3

Worked example
Paper spline worked visits (empty 20-bed community ED, 46000 annual visits)
Given:
admit_time_hours=0critical_care_patients=0ed_beds=20ed_patients=0ed_visits_per_year=46000waiting_room_patients=0
- occupancy D = 0/20 = 0; A = 0; B = 0 h; C = 0; E = 46000
- 0.00126*46000 = 57.96; pmax(E-18811,0)=27189 and pmax(E-43012,0)=2988 enter the cubic spline; later knots are 0
- cedocs_score = -30.39 + 57.96 minus the first cubic plus the second cubic, 1 decimal (paper 0-100 scale, unclamped)
Busy 20-bed community ED at the same annual volume
Given:
admit_time_hours=8critical_care_patients=4ed_beds=20ed_patients=40ed_visits_per_year=46000waiting_room_patients=15
- occupancy D = 40/20 = 2.0; A = 4; B = 8 h; C = 15; E = 46000
- cedocs_score adds 3.00*4 + 0.53*8 + 1.16*15 + 20.66*2.0 to the empty-ED spline intercept, 1 decimal

Parameters
| Name | Type | Required | Description |
|---|---|---|---|
critical_care_patients |
integer | required | Critical-care patients in the ED (integer 0-20). Weiss 2014 reduced-model A. magent does not count patients. |
admit_time_hours |
number | required | Hours the longest-waiting admitted patient has been in the ED since admission (0-120). Weiss 2014 reduced-model B. Not time since registration. magent does not measure wait times. |
waiting_room_patients |
integer | required | Patients in the waiting room (integer 0-200). Weiss 2014 reduced-model C. magent does not count waiting-room patients. |
ed_patients |
integer | required | Total patients in the ED (integer 0-200). Weiss 2014 occupancy numerator (beds plus doubled-up or hallway). magent does not count patients. |
ed_beds |
integer | required | Number of ED beds (integer 1-300). Weiss 2014 occupancy denominator. magent does not count beds. |
ed_visits_per_year |
integer | required | ED visits per year (integer 1000-200000). Weiss 2014 reduced-model E with restricted cubic spline knots at 18811, 43012, 49466, and 67273. The paper's spline worked example uses 46000. magent does not count visits. |
Bulk (POST)
POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.
- 1 to 25 items. Each item uses the same keys as the GET query parameters.
- POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
- The first invalid item fails the whole request (index in the 400 JSON). You are not charged.
- HTTP 200 is {count, path, items}. Each items[i] is the GET 200 body for that row.
- Catalog misses (empty matches, found=false) stay paid 200s inside that slot.
- x402 resource URL is this path plus n and body_sha256. Browsers that prefer text/html get the same paywall as GET; Pay retries POST with the same items.

Payment
Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, invalid params return HTTP 400 JSON before settlement. magent does not charge. Fix the params, then request a new 402 quote for that complete URL. Catalog misses (empty matches, found=false) are valid paid 200s. Unpaid valid requests return HTTP 402 with a base64
PAYMENT-REQUIRED
header. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. Full handshake
and shared payment errors: Payments.
Stdio MCP: /docs/mcp.
Guarantees
- HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON.
- exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. Uncertain or failed settlement fails closed (HTTP 503). Retry the same PAYMENT-SIGNATURE.
- HTTP 402 is unpaid only. Do not sign a second authorization because of a 503.
- Execution is timeout-bounded and concurrency-capped.
- Calculator inputs are stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
