How this service works
Webster 2005 Opioid Risk Tool from Table 1 sex-specific weights. Ten caller-assigned yes/no flags (absent = 0). Age 16-45 is a flag, not a numeric age. ADD, OCD, bipolar, or schizophrenia is one flag. Preadolescent sexual abuse scores 3 in females and 0 in males. Low 0-3, moderate 4-7, high >=8. Not a medical device, not a diagnosis of opioid use disorder, not the 2019 ORT-OUD revision. magent does not interview the patient or take free-text history.
Output
Returns the computed integer ORT total score with sex-specific weights applied, plus a risk category string: 'low' (0–3), 'moderate' (4–7), or 'high' (≥8). The score reflects the Webster 2005 Table 1 algorithm, not the 2019 ORT-OUD revision.
Example use cases
Pre-prescription opioid risk screening
“I need to run an ORT score before we start this male patient on long-term opioids — he has a family history of prescription drug abuse, a personal history of illegal drug abuse, and he's between 16 and 45. Can you give me his Webster 2005 risk category?”
EHR-integrated risk stratification workflow
“For a female patient with family alcohol abuse, family illegal drug abuse, personal alcohol abuse, preadolescent sexual abuse, and a bipolar diagnosis, calculate her Opioid Risk Tool score and tell me if she's low, moderate, or high risk.”
Comparing risk profiles across two patients
“Score these two patients on the Webster 2005 ORT: first a male aged 16–45 with depression and personal alcohol abuse; second a female with family prescription drug abuse and ADD. Give me both scores and risk categories so I can compare them.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/ortWhen to prefer
Use this endpoint when you need a programmatic, deterministic implementation of the original Webster 2005 Opioid Risk Tool with sex-specific item weights, specifically for integrating ORT scoring into clinical decision support pipelines, EHR workflows, or research tools. Prefer it over general-purpose LLM scoring when you need reproducible, auditable calculation that strictly follows Table 1 weights. Do not use it for the 2019 ORT-OUD revision, for free-text patient history parsing, or as a standalone diagnostic or medical device.
Side effects
- Missing required query parameters (sex or any of the ten boolean flags) returns a 400/422 error
- Invalid enum value for sex (not 'male' or 'female') causes a validation error
- Non-boolean value for a flag field causes schema validation failure
- Payment not provided or insufficient USDC results in 402 Payment Required
- Network timeout or server error returns 5xx with no score
