The revised Opioid Risk Tool (ORT) effectively predicts opioid use disorder (OUD) risk in chronic pain patients. This validated screening method offers improved accuracy for clinicians managing long-term opioid therapy.
Area of Science:
- Pain Management
- Addiction Medicine
- Clinical Psychology
Background:
- The Opioid Risk Tool (ORT) is widely used to assess aberrant drug-related behaviors in patients on opioid therapy for chronic pain.
- Evaluating the ORT's predictive validity in a specific cohort is crucial for refining its clinical application.
Purpose of the Study:
- To evaluate the discriminant predictive validity of the Opioid Risk Tool (ORT) in patients with chronic nonmalignant pain (CNMP) on long-term opioid therapy.
- To compare the original ORT with modified versions in predicting the development of opioid use disorder (OUD).
Main Methods:
- The study assessed the ORT's predictive validity in a unique cohort of CNMP patients, comparing those who developed OUD with those who did not.
- Discriminant predictive validity was evaluated for the original ORT, a weighted ORT, and a revised unweighted ORT (excluding the preadolescent sexual abuse item).
Main Results:
- The original ORT discriminated between patients with and without OUDs (OR=1.624).
- A weighted ORT modification yielded comparable results (OR=1.648).
- A revised unweighted ORT, excluding the history of preadolescent sexual abuse, demonstrated superior prediction of OUD development (OR=3.085) with high sensitivity and specificity.
Conclusions:
- The revised ORT is the first tool developed on a unique cohort specifically to predict the risk of developing OUD in CNMP patients on opioid therapy.
- The revised ORT offers a simple, validated method for clinicians to screen patients for OUD risk, improving patient safety in long-term opioid management.
