Opioid Risk Tool (ORT)
Predicts risk of aberrant drug-related behaviour in patients prescribed opioids for chronic pain. Scored separately for male and female patients.
Score interpretation
Low risk of aberrant drug-related behaviour (<6% risk).
→ Standard monitoring with routine follow-up and urine drug screening.
Moderate risk of aberrant opioid use (~28% risk).
→ Enhanced monitoring: frequent follow-up, urine drug screens, pill counts, prescription drug monitoring.
High risk of aberrant drug-related behaviour (~91% risk).
→ Specialist pain/addiction referral before prescribing. Structured opioid therapy agreement. Consider non-opioid alternatives.
Interpretation bands for the ORT. Apply clinical judgement and local guidance.
