‘The wild west of medicine’: A qualitative investigation of the factors influencing Australian health‐care practitioners' delivery of medicinal cannabis

Abstract Introduction Strong patient interest in the use of medicinal cannabis to treat various clinical indications has sparked global legislative changes. Practitioners are vital in implementing regulatory changes and facilitating patient access to medicinal cannabis, however, little is currently known about the factors influencing practitioners' uptake. Recent rapid increases in practitioner applications to prescribe medicinal cannabis in Australia provides a unique backdrop to examine the current factors influencing prescribing behaviours. This qualitative study examined Australian practitioners' perspectives on prescribing medicinal cannabis to provide a comprehensive exploration of the potential factors influencing uptake in clinical practice. Methods Seventeen semi‐structured interviews were conducted with Australian health‐care practitioners. Transcripts were analysed using the Framework approach to thematic analysis and cross‐mapped to appropriate domains of the Theoretical Domains Framework. Results We identified four themes related to the barriers and facilitators to prescribing medicinal cannabis: (i) clinical capabilities needed to prescribe; (ii) prescribing an unapproved therapeutic good; (iii) negative attitudes towards prescribers in the medical community; and (iv) divergent beliefs about clinical utility. Discussion and Conclusions Practitioners face multiple pervasive barriers to prescribing medicinal cannabis. Beliefs about clinical utility appear to be highly influential in shaping prescribing behaviours. Moreover, our findings suggest that a medicinal cannabis ‘specialisation’ has emerged within the Australian medical community. Findings demonstrate that a range of complex and multifaceted factors influence practitioners' medicinal cannabis prescribing behaviours. We highlight several considerations for policy and practice to support safe and appropriate patient access to medicinal cannabis in this emerging area of clinical practice.
