Description of collaborative, fee-for-service, office-based, pharmacist-directed medical cannabis therapy management service for patients with chronic pain.

BACKGROUND: Treatment with medical cannabis (MC) in the United States tends to be patient-driven in nature despite evidence that suggests that patients have remarkably poor knowledge on the medical use of this treatment modality. OBJECTIVE: To develop and pilot a collaborative, fee-for-service (FFS), office-based, pharmacist-directed MC therapy management (MCTM) service for patients suffering chronic pain. PRACTICE DESCRIPTION: A collaborative, FFS, office-based, pharmacist-directed MCTM service where patients are seen after a physician deems them suitable for treatment with MC. The pharmacist designs the initial treatment regimen by selecting a formulation, dose, route, and frequency of administration and then manages ongoing therapy by making regimen changes based on the patient's response, adverse effects, and financial concerns. PRACTICE INNOVATION: The creation of a specialized service where a registered MC pharmacist is positioned in a collaborating provider's office and sees patients face-to-face for the provision of MCTM services. EVALUATION METHODS: Patient retention, revenue generated, and ability to replicate the service were evaluated. Patient satisfaction was assessed by collecting subjective feedback on the service. RESULTS: The pilot site that developed the service has seen 133 patients from 2016 to 2021 and has retained 89% of patients after 5 years of quarterly appointments. Patients appear willing to pay out of pocket for the service, and the revenue generated covers the pharmacist's and collaborating physician's time as well as additional overhead. The service has been replicated at 2 additional sites, and patient feedback has been positive. CONCLUSIONS: MCTM is another useful pharmacist service that patients are willing to pay for. MCTM services decrease the collaborating provider's workload while still allowing them to offer their patients personalized treatment with MC. In our experience, the service retains patients, generates enough revenue to cover costs, can be replicated, and is well received by patients.

Preliminary evaluation of the efficacy, safety, and costs associated with the treatment of chronic pain with medical cannabis.

INTRODUCTION: Medical cannabis (MC) is commonly claimed to be an effective treatment for chronic or refractory pain. With interest in MC in the United States growing, as evidenced by the 29 states and 3 US districts that now have public MC programs, the need for clinical evidence supporting this claim has never been greater. METHODS: This was a retrospective, mirror-image study that investigated MC's effectiveness in patients suffering from chronic pain associated with qualifying conditions for MC in New York State. The primary outcome was to compare European Quality of Life 5 Dimension Questionnaire (EQ-5D) and Pain Quality Assessment Scale (PQAS) scores at baseline and 3 months post-therapy. The secondary outcomes included comparisons of monthly analgesic prescription costs and opioid consumption pre- and post-therapy. Tolerability was assessed by side effect incidence. RESULTS: This investigation included 29 subjects. Quality of life and pain improved, measured by change in EQ-5D (Pre 36 - Post 64, P < .0001) and change in PQAS paroxysmal (Pre 6.76 - Post 2.04, P < .0001), surface (Pre 4.20 - Post 1.30, P < .0001), deep (Pre 5.87 - Post 2.03, P < .0001), unpleasant (Pre "miserable" - Post "annoying", P < .0001). Adverse effects were reported in 10% of subjects. DISCUSSION: After 3 months treatment, MC improved quality of life, reduced pain and opioid use, and lead to cost savings. Large randomized clinical trials are warranted to further evaluate the role of MC in the treatment of chronic pain.
