Barriers in accessing medical cannabis for children with drug-resistant epilepsy in Canada: A qualitative study

Planting the seeds for success: A qualitative study exploring primary healthcare providers' perceptions about medical cannabis

BACKGROUND

In Canada, cannabis legalization altered the way that the public can access cannabis for medical purposes. However, Canadians still struggle with finding healthcare professionals (HCPs) who are involved in medical cannabis counselling and authorization. This raises questions about the barriers that are causing this breakdown in care. Our study explored the perceptions of primary care providers regarding cannabis in their practice.

METHODS

Semi-structured interviews were conducted by Zoom with HCPs in Newfoundland and Labrador (NL) to discuss their experiences with medical and non-medical cannabis in practice. Family physicians and nurse practitioners who were practicing in primary care in NL were included. The interview guide and coding template were developed using the Theoretical Domains Framework (TDF). A thematic analysis across the TDF was then conducted.

RESULTS

Twelve participants with diverse demographic backgrounds and experience levels were interviewed. Five main themes emerged including, knowledge acquisition, internal influences, patient influences, external HCP influences, and systemic influences. The TDF domain resulting in the greatest representation of codes was environmental context and resources.

INTERPRETATION

The findings suggested that HCPs have significant knowledge gaps in authorizing medical cannabis, which limited their practice competence and confidence in this area. Referring patients to cannabis clinics, while enforcing harm-reduction strategies, was an interim option for patients to access cannabis for medical purposes. However, developing practice guidelines and educational resources were suggested as prominent facilitators to promote medical cannabis authorization within the healthcare system.

Cannabidiol and cannabis-inspired terpene blends have acute prosocial effects in the BTBR mouse model of autism spectrum disorder

Introduction

Cannabidiol (CBD) is a non-intoxicating phytocannabinoid with increasing popularity due to its purported therapeutic efficacy for numerous off-label conditions including anxiety and autism spectrum disorder (ASD). Those with ASD are commonly deficient in endogenous cannabinoid signaling and GABAergic tone. CBD has a complex pharmacodynamic profile that includes enhancing GABA and endocannabinoid signaling. Thus, there is mechanistic justification for investigating CBD's potential to improve social interaction and related symptoms in ASD. Recent clinical trials in children with ASD support CBD's beneficial effects in numerous comorbid symptoms, but its impact on social behavior is understudied.

Methods

Here, we tested the prosocial and general anxiolytic efficacy of a commercially available CBD-rich broad spectrum hemp oil delivered by repeated puff vaporization and consumed via passive inhalation in the female cohort of the BTBR strain, a common inbred mouse line for preclinical assessment of ASD-like behaviors.

Results

We observed that CBD enhanced prosocial behaviors using the 3-Chamber Test with a different vapor dose-response relationship between prosocial behavior and anxiety-related behavior on the elevated plus maze. We also identified that inhalation of a vaporized terpene blend from the popular OG Kush cannabis strain increased prosocial behavior independently of CBD and acted together with CBD to promote a robust prosocial effect. We observed similar prosocial effects with two additional cannabis terpene blends from the Do-Si-Dos and Blue Dream strains, and further reveal that these prosocial benefits rely on the combination of multiple terpenes that comprise the blends.

Discussion

Our results illustrate the added benefit of cannabis terpene blends for CBD-based treatment of ASD.

Medical cannabis in schools: The experiences of caregivers

Objectives

Implementing medical cannabis (MC) into a child's daily routine can be challenging and there is a lack of guidance for its therapeutic use in schools in Canada. Our objective was to learn about the experiences of caregivers of school-aged children who require MC.

Methods

Qualitative description was used and caregivers were interviewed about MC in schools and in general. The transcripts were entered into Dedoose software for qualitative analysis and content analysis was performed. Sentences and statements were ascribed line by line into meaning units and labelled with codes, and organized according to categories and subcategories.

Results

Twelve caregivers of school-aged children who take MC participated. The most common reasons for treatment were drug-resistant epilepsy (DRE), autism, or other developmental disorders. Approximately half of the participants' children (n = 6) took MC during the school day and most (5/6) perceived their experiences to be positive or neutral but reported a lack of knowledge about MC. While data saturation was not reached regarding MC in schools, rich dialogues were garnered about MC in general and three categories were identified: challenges (subcategories stigma, finding an authorizer, cost, dosing, and supply); parents as advocates (subcategories required knowledge, attitudes, skills, and sources of information); and caregiver relief for positive outcomes.

Conclusions

Caregivers demonstrate remarkable tenacity despite the many challenges associated with MC use. Education and practice change are needed to ensure that children using MC can benefit from or continue to experience its positive outcomes within the school environment and beyond.

Healthcare practitioner perceptions on barriers impacting cannabis prescribing practices

Background

Canadians seeking medical cannabis (MC) may encounter difficulties in finding a healthcare provider (HCP) who authorizes their access to it. Barriers that HCPs face in authorizing MC are unclear. The objectives of this study were to evaluate HCP opinions, knowledge, comfort, and practice in MC prescribing and counseling on recreational cannabis use, and whether the COVID-19 pandemic affected MC prescribing practices.

Methods

Eligible participants included HCPs (e.g., attending physicians, nurses, pharmacists) in Canada. A questionnaire evaluating their knowledge, comfort, and practice in medical and recreational cannabis was designed based on instruments developed in previous studies. Between April 13th-December 13th 2021, ninety-one healthcare associations were asked to distribute the survey to their members, and an advertisement was placed in the online Canadian Medical Association Journal. Descriptive statistics were used to analyze the results.

Results

Twenty-four organizations agreed to disseminate the survey and 70 individuals completed it. Of respondents, 71% were attending physicians or medical residents, while the remainder were nurses, pharmacists or other HCPs. Almost none (6%) received training in MC in professional school but 60% did receive other training (e.g., workshops, conferences). Over half (57%) received more questions regarding MC since recreational cannabis was legalized, and 82% reported having patients who use MC. However, 56% felt uncomfortable or ambivalent regarding their knowledge of MC, and 27% were unfamiliar with the requirements for obtaining MC in Canada. The most common symptoms for recommending MC were pain and nausea, whereas the most common conditions for recommending it were cancer and intractable pain. The strongest barrier to authorizing MC was uncertainty in safe and effective dosage and routes of administration. The strongest barrier to recommending or authorizing MC was the lack of research evidence demonstrating its safety and efficacy. During the pandemic, many respondents reported that a greater number of their patients used cannabis to relieve anxiety and depression.

Conclusions

Our results suggest that HCPs across Canada who responded to our survey are unfamiliar with topics related to MC. The strongest barriers appear to be lack of clinical research, and uncertainty in safe and effective MC administration. Increasing research, training, and knowledge may help HCPs feel more equipped to make informed treatment/prescribing decisions, which may help to improve access to MC.

Clinician views on and ethics priorities for authorizing medical cannabis in the care of children and youth in Canada: a qualitative study

BACKGROUND

The use of cannabis for medical purposes by pediatric patients is expanding across Canada; however, supporting evidence, federal regulations and treatment guidelines are lacking. To understand factors affecting treatment decisions in this landscape, we sought to delineate clinician perspectives, ethics priorities and values for cannabis authorization.

METHODS

We sampled participants purposefully through Canadian Childhood Cannabinoid Clinical Trials listservs, which include the majority of pediatric oncologists and palliative care physicians practising in Canada, among many other pediatric physicians and clinicians. Inclusion criteria were being a practising clinician in Canada, involvement in the care of children and willingness to be interviewed regardless of stance on medical cannabis. In November and December 2020, we conducted semistructured interviews focusing on principles, values and priorities, including medical, professional, regulatory, evidentiary and social considerations, for authorizing medical cannabis to children. Interviews were recorded, transcribed and analyzed by means of deductive and inductive thematic methods.

RESULTS

We conducted 18 interviews with a diverse group of clinicians representing a range of specialties within pediatric care, including neurology, palliative care, oncology, family medicine and pharmacology. The interviews yielded 4 themes and 12 subthemes related to a priori (medical, professional, regulatory, evidentiary and social themes) and emergent themes. The 4 themes of access, relationships and relational autonomy (autonomy within relationships), medically appropriate use and research priorities were grounded in principles of harm reduction. Participants described problematic authorization procedures that negatively affect patient use. Principles associated with relational autonomy were highlighted as a feature of open clinical communication. Benefits of appropriate medical uses weighed positively over risks, even in the context of potential effects on neurodevelopment. Participants expressed that more research is essential to align medical cannabis with biomedical standards.

INTERPRETATION

Clinicians reported pursuing ethical use of medical cannabis for pediatric patients and prioritizing their safety under principles of harm reduction. There is a need for evidence about neurodevelopmental risks, support for research, treatment guidelines and greater knowledge about stakeholder perspectives to alleviate burdens related to use of medical cannabis for pediatric patients in Canada.

Coverage of medical cannabis by Canadian news media: Ethics, access, and policy

BACKGROUND

The use of recreational cannabis by adults was legalized in Canada in 2018 (The Cannabis Act, 17 October 2018). This change in drug policy indirectly opened the doors to broader uses, including those for health-related conditions. As a first step towards understanding ethical, legal, and social shifts on this landscape, we examined messaging surrounding medical cannabis and health in Canadian news media before and after legalization.

METHODS

We retrieved news articles about medical cannabis and health from Canadian sources (2010-2020). Deductive and inductive content analytic approaches were applied to code eligible articles for both a priori ethical, legal, social, and issues, and emergent themes. Wilcoxon-Mann-Whitney U tests were used to test for thematic changes pre- and post-legalization.

RESULTS

Two hundred and sixteen (216) articles met inclusion criteria. Analysis yielded three themes and eight subthemes, comprising 4931 coded references. The a priori theme of Ethical, Legal and Social Issues (access, benefits/risks of medical cannabis, public engagement, and conflicts of interest) dominated news media coverage across the decade (coded in 99% of articles). The emergent theme of Medical Applications (therapeutic use of cannabis, consumption considerations, comparisons to other drug and treatment options) was coded in 86% of articles; Resource Issues (research and education) in 50%. We found little discourse on ethics issues specific to exceptional populations. Coverage on aspects of access declined significantly post-legalization.

CONCLUSION

Capturing the push of Canadian news coverage of medical cannabis is a powerful means of understanding how public opinions on the subject are shaped and then, by extension, inform public policy for well-being and healthcare. Continued examination of these issues, public consultation, engagement with diverse populations such as people with disabilities and neurologic and mental health conditions, and integration of diverse cultural views into the policy discourse are critical steps for future research and action.

Virtual epilepsy clinics - A Canadian Comprehensive Epilepsy Center experience pre-COVID and during the COVID-19 pandemic period

Objective

The objective of this study is to assess the role of prior experience with virtual care (through e-visits) in maintaining continuity in ambulatory epilepsy care during an unprecedented pandemic situation, comparing in person versus e-visit clinic uptake.

Methods

This is an observational study on virtual epilepsy care (through e-visits) over two years, during a pre-COVID period (14 months) continuing into the COVID-19 pandemic period (10 months). For a small initial section of patients seen during the study period a physician survey and a patient satisfaction survey were completed (n = 53). Outcomes of eVisits were analyzed using descriptive statistics.

Results

Median numbers of epilepsy clinic visits conducted during the COVID-19 period (27.5 new and 113 follow up) remained similar to the median uptake during the pre-COVID period (28 new and 116 follow up). Prior experience with e-visits for epilepsy yielded smooth transition into the pandemic period, with several other advantages. The majority of eVisits were successful despite technical difficulties and major components of history and management were still easily implemented. Results from patient surveys supported that a significant amount of time and money were saved, which was in keeping with our health-economic analysis.

Conclusion

Our study is one of the first few reports of fully integrated virtual care in a comprehensive epilepsy clinic starting much before start of the COVID-19 pandemic. The results of our study support the feasibility of using virtual care to deliver specialized outpatient care in a comprehensive epilepsy center.
