# SETscore tracheostomy need SETscore Status: LIVE Price: $0.005 USDC `GET /api/calc/setscore` HTML: https://magentlab.com/docs/setscore Markdown: https://magentlab.com/docs/setscore.md Not a medical device. Not a diagnosis, dose, or listing recommendation. ## What it computes Sum the fifteen Schönenberger 2016 SETscore items from caller-assigned flags and return whether the total is elevated (score ≥ 8). ## When to use When an agent already has the fifteen Schönenberger 2016 Table 1 items assigned as present or absent and needs the published 0–48 total and the 2016 ROC cut-off of 8, not a tracheostomy order, NIHSS total, APACHE II computation, or SETPOINT2 enrollment threshold. ## When not to use - Not a medical device. Not a tracheostomy order, timing decision, or airway procedure. magent does not examine the patient, read imaging, or compute APACHE II, lung injury score, or PaO2/FiO2. - Each of the 15 items is a caller-assigned boolean from Schönenberger 2016 Table 1. magent does not invent extra weights or probabilities. - elevated and setscore_ge_8 are true iff score ≥ 8, the 2016 ROC cut-off for prolonged NICU stay, ventilation time, and tracheostomy need. This is not the SETPOINT2 enrollment threshold of >10 and not NIHSS. ## Formula ``` SETscore = 4*dysphagia + 3*observed_aspiration + 3*gcs_lt_10 + 4*brainstem_lesion + 3*space_occupying_cerebellar + 4*mca_infarct_gt_two_thirds + 4*ich_volume_gt_25_ml + 3*diffuse_lesion + 4*hydrocephalus + 2*neurosurgical_intervention + 3*additional_respiratory_disease + 2*pao2_fio2_lt_150 + 4*apache_ii_gt_20 + 2*lung_injury_score_gt_1 + 3*sepsis; max 48; elevated / setscore_ge_8 iff score >= 8 (Schönenberger 2016) ``` ## Citation [The SETscore to Predict Tracheostomy Need in Cerebrovascular Neurocritical Care Patients](https://doi.org/10.1007/s12028-015-0235-5) Schönenberger S, Al-Suwaidan F, Kieser M, Uhlmann L, Bösel J Neurocrit Care. 2016;25(1):94-104 DOI: [10.1007/s12028-015-0235-5](https://doi.org/10.1007/s12028-015-0235-5) ## Worked example ### All fifteen flags false Given: `additional_respiratory_disease=false, apache_ii_gt_20=false, brainstem_lesion=false, diffuse_lesion=false, dysphagia=false, gcs_lt_10=false, hydrocephalus=false, ich_volume_gt_25_ml=false, lung_injury_score_gt_1=false, mca_infarct_gt_two_thirds=false, neurosurgical_intervention=false, observed_aspiration=false, pao2_fio2_lt_150=false, sepsis=false, space_occupying_cerebellar=false` 1. All 15 Schönenberger 2016 Table 1 flags false → 0 each 2. Score = 0 (max 48); elevated and setscore_ge_8 are false because score < 8 ### Dysphagia and ICH volume >25 mL (cut-off 8) Given: `additional_respiratory_disease=false, apache_ii_gt_20=false, brainstem_lesion=false, diffuse_lesion=false, dysphagia=true, gcs_lt_10=false, hydrocephalus=false, ich_volume_gt_25_ml=true, lung_injury_score_gt_1=false, mca_infarct_gt_two_thirds=false, neurosurgical_intervention=false, observed_aspiration=false, pao2_fio2_lt_150=false, sepsis=false, space_occupying_cerebellar=false` 1. dysphagia true → +4; ich_volume_gt_25_ml true → +4; remaining flags false → 0 2. Score = 8 (max 48); elevated and setscore_ge_8 are true because score >= 8 ### Dysphagia and space-occupying cerebellar lesion (below cut-off) Given: `additional_respiratory_disease=false, apache_ii_gt_20=false, brainstem_lesion=false, diffuse_lesion=false, dysphagia=true, gcs_lt_10=false, hydrocephalus=false, ich_volume_gt_25_ml=false, lung_injury_score_gt_1=false, mca_infarct_gt_two_thirds=false, neurosurgical_intervention=false, observed_aspiration=false, pao2_fio2_lt_150=false, sepsis=false, space_occupying_cerebellar=true` 1. dysphagia true → +4; space_occupying_cerebellar true → +3; remaining flags false → 0 2.

The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement. Method: `POST /api/calc/setscore` Max items: 25 Price: unit_amount + extra_item_amount * (n - 1) (unit 5000 atomic, extra 2000 atomic) Status: 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.

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. - GET the tool with Accept: application/json (do not send Accept: text/html unless you want the human paywall). - HTTP 402 means you have not paid. Decode the base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote. - Sign accepts[0] (exact, EIP-3009) with validBefore = now + maxTimeoutSeconds (600 seconds), or accepts[1] (batch-settlement deposit/voucher) on product GET. Ping and POST {items} stay exact. Magent retries transient facilitator 429/5xx before answering. - Retry the same URL with PAYMENT-SIGNATURE (base64 JSON of accepted and payload). Magent attaches canonical extensions.bazaar on CDP verify/settle; echoing 402 bazaar is optional. - Success is HTTP 200 JSON plus PAYMENT-RESPONSE. exact settles before the tool. batch-settlement verifies (and deposit-settles) before the tool and commits the charge after HTTP 2xx. HTTP 503: retry the same PAYMENT-SIGNATURE. Mint a new exact nonce only after a new HTTP 402. - offered `exact` on eip155:8453: Fixed-price USDC on Base. The buyer authorizes the advertised amount (EIP-3009). magent settles before the tool runs (paymentFlow upfront). extra.assetTransferMethod=eip3009 extra.paymentFlow=upfront. - offered `batch-settlement` on eip155:8453: Payment-channel vouchers claimed later in batches. Exact stays accepts[0]. Same-path POST {items} is still exact. extra.assetTransferMethod=eip3009 extra.paymentFlow=authorization. - not offered `upto`: Not offered. Usage-based: buyer authorizes a ceiling, seller settles the actual amount after work. Reserved for a future metered tool. Not for current calculators or code search. Same-path POST {items} is still scheme exact: one EIP-3009 authorization for GET unit plus $0.002 per extra item. That is not x402 batch-settlement (payment channels / vouchers). Shared HTTP 402 and 503 table: https://magentlab.com/docs/payments Stdio MCP (one process per host): https://magentlab.com/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.
