BAWS (Brief Alcohol Withdrawal Scale)

Sum the five Rastegar 2017 Brief Alcohol Withdrawal Scale items (tremor, diaphoresis, agitation, orientation, hallucinations; each caller-assigned integer 0-3) and return the published 0-15 total plus whether BAWS >=3, the cut that predicted CIWA-Ar >=8 in that paper.

Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

When to use

When an agent already has Rastegar 2017 BAWS 0-3 integers for the five signs and needs the published total and the >=3 CIWA-Ar >=8 prediction cut. magent does not examine the patient or order benzodiazepines.

When not to use

Not a medical device and not a benzodiazepine, symptom-triggered, or treatment order. magent does not examine the patient.
Each of tremor, diaphoresis (sweats), agitation, confusion/orientation, and hallucinations is a caller-assigned integer 0-3. magent does not observe the patient.
Rastegar 2017: BAWS >=3 predicted CIWA-Ar >=8 (sensitivity 85.3%, specificity 65.8% in that paper). That is a published operating characteristic, not a diagnosis.
Does not emit later ICU papers' dose bands or website diazepam protocols (3-5 / 6-8 / >8). Those are not the 2017 derivation cuts.

Formula

BAWS = tremor + diaphoresis + agitation + orientation + hallucinations; each a caller-assigned integer 0-3; max 15; Rastegar 2017; predicts_ciwa_ar_ge_8 iff score >= 3

Citation

Title: Development and Implementation of an Alcohol Withdrawal Protocol using a 5-Item Scale, the Brief Alcohol Withdrawal Scale (BAWS)
Authors: Rastegar DA, Applewhite D, Alvanzo AAH, Welsh C, Niessen T, Chen ES

DOI: 10.1080/08897077.2017.1354119

Worked example

All five items 0

Given: agitation=0diaphoresis=0hallucinations=0orientation=0tremor=0

tremor 0 + diaphoresis 0 + agitation 0 + orientation 0 + hallucinations 0
Score = 0 (max 15); predicts_ciwa_ar_ge_8 false

Score 3 at the published CIWA-Ar >=8 prediction cut

Given: agitation=1diaphoresis=1hallucinations=0orientation=0tremor=1

tremor 1 + diaphoresis 1 + agitation 1 + orientation 0 + hallucinations 0
Score = 3 (max 15); predicts_ciwa_ar_ge_8 true (Rastegar 2017 BAWS >=3 predicted CIWA-Ar >=8). Not a benzodiazepine order.

All five items 3

Given: agitation=3diaphoresis=3hallucinations=3orientation=3tremor=3

each of the five Rastegar 2017 items is 3 as assigned by the caller
Score = 15 (max 15); predicts_ciwa_ar_ge_8 true. Not a benzodiazepine order.

Parameters

Name	Type	Required	Description
`tremor`	integer	required	Caller-assigned Rastegar 2017 BAWS tremor points (integer 0-3). magent does not examine the patient.
`diaphoresis`	integer	required	Caller-assigned Rastegar 2017 BAWS diaphoresis (sweats) points (integer 0-3). magent does not examine the patient.
`agitation`	integer	required	Caller-assigned Rastegar 2017 BAWS agitation points (integer 0-3). magent does not examine the patient.
`orientation`	integer	required	Caller-assigned Rastegar 2017 BAWS confusion/orientation points (integer 0-3). magent does not examine the patient.
`hallucinations`	integer	required	Caller-assigned Rastegar 2017 BAWS hallucinations points (integer 0-3). One item, not separate CIWA-Ar tactile/auditory/visual scores. magent does not examine the patient.

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.

POST /api/calc/baws Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

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.

Client errors (HTTP 400)

Invalid params return 400 without charge. Shared HTTP 402 and 503 meanings: Payments.

HTTP	Code	When
400	`invalid_baws`	BAWS items must be integers in the Rastegar 2017 published 0-3 range for those five signs. Returned before settlement; you are not charged.
400	`invalid_items`	POST body must be a JSON object with only an items array Returned before settlement; you are not charged.
400	`invalid_item_count`	items must be an array of 1 to 25 objects Returned before settlement; you are not charged.
400	`invalid_item`	each items entry must be a JSON object Returned before settlement; you are not charged.

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.
