Interventions

Prospective prior authorization (PA) with hard stops in Washingtonother

Under Washington regulatory procedures, payment for any opioid prescription billed beyond six weeks after the injury is denied unless the prescriber has submitted a checklist attesting to completion of all best practices from the regulations/guidelines.Thus, the Washington intervention is prospective and includes a "hard stop" subject to an insurer's decision based on regulatory authority.

Retrospective review (RR) with prescriber notification in Ohioother

In Ohio an automated report identifies new opioid prescriptions beyond the acute phase. Ohio Workers' Compensation pharmacy and clinical staff review the medical record at 12 weeks to determine whether best practices were met. If not, the prescriber is notified via letter, and cases are reviewed again at 16 weeks. If best practices have still not been met, the prescriber and worker are notified via letter that opioid coverage will end in 4 weeks. The Ohio program relies on retrospective chart review and communication of best practices to prescribers.
