An early economic analysis of medical cannabis for the treatment of chronic pain

Abstract

Background: Cannabis-based medicinal products (CBMPs) are increasingly demonstrating effectiveness in treating a wide range of conditions, with a relatively high safety profile in clinical usage compared to other prescription pain medications and few contraindications. Consultation and other prescription-related costs are, at present, higher for CBMPs than for some other treatment options, leading to some concern around wider prescribing. Research design and Methods: An early cost-effectiveness model was developed to estimate the impact of prescribing CBMPs alone and/or in addition to analgesics, physiotherapy, and cognitive behavioral therapy for chronic pain in the UK for 1 year. Results: Due to their comparative effectiveness, CBMPs were found to be cost saving. Various scenarios were model tested; in all scenarios where CBMPs decrease pain-level states, less resource use is required. Increased efficacy of 5% was conservatively assumed based on current Real-World Evidence. In this scenario, CBMPs were significantly more cost-effective, and as costs relating to the prescribing of these continue to fall, relative savings are predicted to increase. Conclusion: These findings highlight the substantial cost saving that CBMPs may represent for the treatment of chronic pain patients, and the benefits for healthcare providers as a treatment for this often hard-to-treat population.
