Objective: To analyze the validity of the Opioid Risk Tool (ORT) in a large. diverse population.
Design: A cross-sectional descriptive study.
Setting: Academic tertiary pain management center.
Subjects: A total of 225 consecutive new patients, aged 18 years or older.
Methods: Data collection included demographics, ORT scores, aberrant behaviors, pain intensity scores, opioid type and dose, smoking status, employment, and marital status.
Results: In this population, we were not able to replicate the findings of the initial ORT study. Self-report was no better than chance in predicting those who would have an opioid aberrant behavior. The ORT risk variables did not predict aberrant behaviors in either gender group. There was significant disparity in the scores between self-reported ORT and the ORT supplemented with medical record data (enhanced ORT). Using the enhanced ORT, high-risk patients were 2.5 times more likely to have an aberrant behavior than the low-risk group. The only risk variable associated with aberrant behavior was personal history of prescription drug misuse.
Conclusions: The self-report ORT was not a valid test for the prediction of future aberrant behaviors in this academic pain management population. The original risk categories (low, medium, high) were not supported in the either the self-reported version or the enhanced version; however, the enhanced data were able to differentiate between high- and low-risk patients. Unfortunately, without technological automation, the enhanced ORT suffers from practical limitations. The self-report ORT may not be a valid tool in current pain populations; however, modification into a binary (high/low) score system needs further study.
