Despite data supporting its efficacy, barriers to implementation of buprenorphine for office-based treatment are present. Complications can occur during buprenorphine inductions, yet few published studies have examined this phase of treatment. To examine factors associated with complications during buprenorphine induction, we conducted a retrospective chart review of the first 107 patients receiving buprenorphine treatment in an urban community health center. The primary outcome, defined as complicated induction (precipitated or protracted withdrawal), was observed in 18 (16.8%) patients. Complicated inductions were associated with poorer treatment retention (than routine inductions) and decreased over time. Factors independently associated with complicated inductions included recent use of prescribed methadone, recent benzodiazepine use, no prior experience with buprenorphine, and a low initial dose of buprenorphine/naloxone. Findings from this study and further investigation of patient characteristics and treatment characteristics associated with complicated inductions can help guide buprenorphine treatment strategies.

Recent legislation permits the treatment of opioid-dependent patients with buprenorphine in the primary care setting, opening doors for the development of new treatment models for opioid dependence. We modified national buprenorphine treatment guidelines to emphasize patient self-management by giving patients the opportunity to choose to have buprenorphine inductions at home or the physician’s office. We examined whether patients who had home-based inductions achieved greater 30-day retention than patients who had traditional office-based inductions in a study of 115 opioid-dependent patients treated in an inner-city health center. Retention was similar in both groups: 50 (78.1%) in office-based group versus 40 (78.4%) in home-based group, p = .97. Several patient characteristics were associated with choosing office- versus home-based inductions, which likely influenced these results. We conclude that opioid dependence can be successfully managed in the primary care setting. Approaches that encourage patient involvement in treatment for opioid dependence can be beneficial.

Although novel buprenorphine induction strategies are emerging, they have been inadequately studied. To examine our newly developed patient-centered home-based inductions, we conducted a subgroup analysis of 79 opioid-dependent individuals who had buprenorphine inductions at an urban community health center. Participants chose their induction strategy; standard-of-care office-based inductions were physician-driven, with multiple assessments, and observed, and patient-centered home-based inductions emphasized patient self-management and included a "kit" for induction at home. We conducted interviews and extracted medical records. Using mixed nonlinear models, we examined associations between induction strategy and opioid use and any drug use. Compared to those with standard-of-care office-based inductions, participants with patientcentered home-based inductions had no significant differences in opioid use (AOR=0.63, 95%CI=0.13-2.97), but greater reductions in any drug use (AOR=0.05, 95%CI=0.01-0.37). Taking into account the limitations of our observational cohort study design, we conclude that participants with patient-centered home-based inductions had similar reductions in opioid use and greater reductions in any drug use than those with standard-of-care office-based inductions. It is essential that new induction strategies be based on existing models or theories and well-studied.
