Persistence, the duration a patient remains on therapy, in chronic, symptomatic conditions plays an important role in therapy effectiveness. Understanding the duration and patient factors associated with prescribed medication persistence is, therefore, an important step toward better treatment and health outcomes for patients. In the following study, an analysis of such factors associated with buprenorphine transdermal system (BTDS) persistence was conducted utilizing a large US private practitioner and pharmacy claims database and is herein reported. ⋯ Prior and concomitant use of adjuvant analgesics, prior use of opioids, and dose adjustments were associated with significantly longer persistence among patients initiating BTDS. The results suggest that patients are less likely to discontinue BTDS early if practitioners account for prior treatment history and dose titration.
