Changes in Opioid Utilization Following Tumor Necrosis Factor Inhibitor Initiation in Patients with Rheumatoid Arthritis

Introduction Pain control is one of the most important aspects of rheumatoid arthritis (RA) management from the patient’s perspective. Newer generations of RA treatment including tumor necrosis factor inhibitor (TNFi) have the potential to alleviate pain and thus reduce opioid utilization. However, patterns of opioid utilization before and after TNFi initiation have not been well characterized. This study aims to examine multiple measures of change in opioid utilization after the initiation of TNFi.
