Context: Health plan disenrollment may disrupt chronic or preventive care for patients prescribed long-term opioid therapy (LTOT).
Purpose: To assess whether overdose events in patients prescribed LTOT are associated with subsequent health plan disenrollment.
Design: Retrospective cohort study.
Background: To help prevent overdose deaths involving prescription drugs, accurate linkage of prescription drug monitoring program (PDMP) records for individual patients is essential.
Objectives: To compare the accuracy of the linkage program used by California's PDMP against various record linkage programs with respect to accuracy in deduplicating patient identities in the PDMP, with implications for identifying high-risk opioid use and outlier behaviors.
Research Design: We evaluated California's program, Link Plus, LinkSolv, and The Link King on 557 861 PDMP identity records with addresses in two 3-digit zip code areas for patients who filled a controlled substance prescription in 2013.
Importance: Patients prescribed long-term opioid therapy are increasingly undergoing dose tapering. Recent studies suggest that tapering is associated with short-term risks of substance misuse, overdose, and mental health crisis, although lower opioid dose could reduce risks of adverse events over the longer term.
Objective: To assess the longer-term risks of overdose or mental health crisis associated with opioid dose tapering.
