Used clinically by primary care and pain specialists to justify the initiation or continuation of long-term opioid therapy.

Best applied when considering placing a patient with chronic non-cancer pain on a continuous opioid contract.

D (Diagnosis): Validates the anatomical/pathological severity of the pain generator.

I (Intractability): Ensures non-opioid, less risky modalities have been exhausted.

R (Risk): A multimodal check of reliability, psychological resilience, and addiction risk.

E (Efficacy): Determines if opioids actually improve the functional baseline without requiring constant upward titration.

The DIRE score uniquely incorporates "Social Support" and "Reliability", recognizing that opioid management requires a stable external environment.

Patients with a score below 14 should generally be treated with interventional procedures (injections/blocks), physical therapy, and non-opioid medications rather than chronic opioids, due to an overwhelmingly high risk of therapy failure.

Score 7 - 13: Not a candidate for long-term opioid management. Failure or addiction is highly likely.

Score 14 - 21: Good candidate. Favorable prognosis for safe and effective long-term therapy.
