Cheatle 2019 revised Opioid Risk Tool (ORT-OUD)
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.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
