ABSTRACT: Purpose
Although the effectiveness of medial branch nerve radiofrequency ablation (RFA) for lumbosacral facet pain has been described, little is known regarding patterns of repeat RFA utilization and prescription opioid use afterward.Design
Retrospective cohort analysis.Patient sample
Patients undergoing lumbosacral RFA in MarketScan from 2007 to 2016.Methods
The time until and number of staged RFAs (<180 days after initial RFA) and repeat RFAs (≥180 days after initial RFA), as well as opioid use at 90 and 180 days after RFA were assessed. Survival analyses were employed to estimate subsequent RFA rates, whereas subsequent RFA frequencies were estimated with inverse probability weighting. Repeated measures testing was performed comparing opioid use pre- and
