Evidence status: CURRENT WORKERS’ COMPENSATION MONITORING FRAMEWORK. Colorado’s workers’ compensation opioid-management rules pair the agreement with drug testing, PDMP review, functional assessment, and coordinated prescribing.

One prescribing practitioner

The chronic-pain guideline states that ongoing long-term opioid prescriptions should come from a single practitioner.

PDMP review

Long-term management includes review of the Colorado Prescription Drug Monitoring Program.

Drug screening

Colorado’s chronic-pain guideline calls for drug screening initially and randomly at least annually and as deemed appropriate by the prescribing physician. Workers’ compensation Rule 18 separately requires urine drug testing for subacute and chronic opioid management.

Rule 18 testing standard

For subacute and chronic opioid management, testing must use methodologies that meet or exceed industry standards for sensitivity, specificity, and accuracy. Testing is required before initial long-term opioid treatment and must be repeated randomly at least annually, with additional testing allowed when documented clinical justification exists.

Functional review

Long-term management requires ongoing documentation of pain relief, functional status, appropriate medication use, and side effects. The chronic-pain guideline calls for full review at least every three months.

Agreement cooperation

The guideline states that continuation of opioid medication is contingent on cooperation with the maintenance program and that use of non-prescribed drugs may lead to tapering.
