How this service works
Cheatle 2019 revised Opioid Risk Tool (ORT-OUD): nine unweighted yes/no flags (each 1; max 9). No sex. No preadolescent sexual abuse item. Scores 0-2 are non_oud; 3 or more are oud (integer cutoff for the paper's 2.5). Not Webster 2005 weighted ORT. Cheatle 2019 enrolled only Caucasian patients of European descent (parent-study genotype design); that is a population limit, not a race coefficient. Not a diagnosis of opioid use disorder. magent does not interview the patient. Not a medical device.
Output
Returns the integer ORT-OUD total score (0–9) and a risk category string: 'non_oud' for scores 0–2, or 'oud' for scores 3 and above, based on Cheatle 2019 methodology with nine unweighted yes/no items.
Example use cases
Pre-opioid prescription OUD risk screen
“Before we prescribe long-term opioids, run the Cheatle ORT-OUD on this patient: family alcohol history yes, no family drug history of any kind, personal prescription drug abuse yes, personal illegal drug use no, personal alcohol abuse no, age 16-45 yes, depression yes, no ADD or bipolar or schizophrenia — are they OUD risk or not?”
EHR-integrated risk flag at point of care
“I'm pulling this patient's chart — family history positive for illegal drugs, negative for alcohol and prescription drugs, personal history negative for all three, patient is 52 so age flag is false, no depression, no ADD/OCD/bipolar/schizophrenia — compute their ORT-OUD score so I can document it.”
Research cohort opioid risk stratification
“I have a study participant with the following flags for the nine-item Cheatle ORT-OUD: family alcohol true, family illegal drugs true, family prescription drugs false, personal alcohol false, personal illegal drugs false, personal prescription drugs false, age 16-45 true, ADD/OCD/bipolar/schizophrenia false, depression false — give me their score and whether they fall in the oud or non_oud group.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/ort_oudWhen to prefer
Use this endpoint when you need to apply specifically the Cheatle 2019 revised ORT-OUD (nine unweighted yes/no flags, no sex item, integer cutoff at 3, non_oud/oud output) rather than the original Webster 2005 weighted ORT. Prefer this for automated clinical decision support pipelines, EHR integrations, or research workflows where a standardized, reproducible, server-side calculation is required. Not appropriate when you need the weighted Webster ORT, a formal diagnostic assessment, or patient-facing interview tooling.
Side effects
- Missing required query parameter returns validation error
- Non-boolean value for any flag causes a schema rejection
- All nine flags must be explicitly provided; partial submission is invalid
- Score is not a clinical diagnosis and should not be interpreted as one; misuse may occur if the caller conflates oud classification with a formal OUD diagnosis
