All patients who screen positive for opioid use disorder should then be administered a diagnostic interview using the DSM-5 Clinical Diagnostic Criteria for Opioid Use Disorder to confirm the diagnosis and assess the severity of OUD. 

According to studies to date, the DSM-5-TR criteria have substantial test-retest reliability in establishing the presence of OUD (Kappa coefficient=0.67; CI: 0.58 0.76) and excellent reliability in determining the severity of OUD (intraclass correlation coefficient (ICC)=0.86; CI: 0.81 0.90).^1,2

The DSM-5-TR criteria are detailed in Appendix 2.
