Collaborative models of care where pharmacists work alongside physicians have been developed for a range of physical health conditions, with benefits including improved patient outcomes and increased access to ongoing care. Opioid agonist treatment (methadone and buprenorphine) is a clinically effective and cost-effective treatment for opioid use disorder that is under-utilized in many countries due to a shortage of prescribers. In recent years, there has been increased interest in the development of collaborative models that utilize pharmacists to overcome barriers to treatment. In this article, we present a narrative review to synthesise recent work in this rapidly developing area.
Recent findings
Two key aspects of opioid agonist treatment were identified: Collaborative models have utilized pharmacists to facilitate buprenorphine induction, and collaborative models provide increased capacity for delivering ongoing care in a variety of settings and patient groups where prescriber access is limited. Pharmacists have undertaken direct patient care responsibilities with varying degrees of autonomy, with benefits including a reduction in prescriber workload, and improvements in treatment retention and continuity of care.
Summary
Collaborative models in which pharmacists are responsible for buprenorphine induction and ongoing management with methadone and buprenorphine have been shown to reduce demands on prescribers while improving or maintaining patient outcomes, and appear feasible and acceptable in a wide range of outpatient settings.
