ABSTRACT
Background: One in five individuals live with chronic pain globally, which often co-occurs with sleep problems, anxiety, depression, and substance use disorders. Although these conditions are commonly managed with cannabinoid-based medicines (CBM), health care providers report lack of information on the risks, benefits, and appropriate use of CBM for therapeutic purposes. Aims: We present these clinical practice guidelines to help clinicians and patients navigate appropriate CBM use in the management of chronic pain and co-occurring conditions. Materials and Methods: We conducted a systematic review of studies investigating the use of CBM for the treatment of chronic pain. Articles were dually reviewed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Clinical recommendations were developed based on available evidence from the review. Values and preferences and practical tips have also been provided to support clinical application. The GRADE system was used to rate the strength of recommendations and quality of evidence. Results: From our literature search, 70 articles met inclusion criteria and were utilized in guideline development, including 19 systematic reviews and 51 original research studies. Research typically demonstrates moderate benefit of CBM in chronic pain management. There is also evidence for efficacy of CBM in the management of comorbidities, including sleep problems, anxiety, appetite suppression, and for managing symptoms in some chronic conditions associated with pain including HIV, multiple sclerosis, fibromyalgia, and arthritis. Conclusions: All patients considering CBM should be educated on risks and adverse events. Patients and clinicians should work collaboratively to identify appropriate dosing, titration, and administration routes for each individual. Systematic Review Registration: PROSPERO no. 135886.

BACKGROUND: Since 2001, Canadians have been able to obtain cannabis for medical purposes, initially through the Access to Cannabis for Medical Purposes Regulations (ACMPR). The Cannabis Act (Bill C-45) came into force on October 17, 2018, replacing the ACMPR. The Cannabis Act enables Canadians to possess cannabis purchased from a licensed retailer without authorization for either medical or nonmedical purposes. The Cannabis Act is currently the guiding legislation which governs both medical and nonmedical access. The Cannabis Act contains some improvements for patients but is essentially the same as its previous legislation. Beginning in October 2022, the federal government is conducting a review of the Cannabis Act and is questioning whether a distinct medical cannabis stream is still required, given the ease of access to cannabis and cannabis products. Although there is overlap in the reasons for medical and recreational cannabis use, the distinct legislation of medical versus recreational use of cannabis in Canada may be under threat. MAIN BODY: A large segment of the medical, academic, research, and lay communities agree that there is a need for distinct medical and recreational cannabis streams. Perhaps most importantly, separation of these streams is necessary to ensure that both medical cannabis patients and healthcare providers receive the required support needed to optimize benefits while minimizing risks associated with medical cannabis use. Preservation of distinct medical and recreational streams can help to ensure that needs of different stakeholders are met. For example, patients require guidance in the form of assessing the appropriateness of cannabis use, selection of appropriate products and dosage forms, dosing titration, screening for drug interactions, and safety monitoring. Healthcare providers require access to undergraduate and continuing health education as well as support from their professional organizations to ensure medical cannabis is appropriately prescribed. Although there are challenges in conducing research, as motives for cannabis use frequently straddle boundaries between medical versus recreational cannabis use, maintenance of a distinct medical stream is also necessary to ensure adequate supply of cannabis products appropriate for medical use, to reduce stigma associated with cannabis in both patients and providers, to help enable reimbursement for patients, to facilitate removal of taxation on cannabis used for medical purposes, and to promote research on all aspects of medical cannabis. CONCLUSION: Cannabis products for medical and recreational purposes have different objectives and needs, requiring different methods of distribution, access, and monitoring. HCPs, patients, and the commercial cannabis industry would serve Canadians well to continue to advocate to policy makers to ensure the continued existence of two distinct streams and must strive to make ongoing improvements to the current programs.
ABSTRACT
PURPOSE: Pancreatic cancer is a lethal disease. Many patients experience a heavy burden of cancer-associated symptoms and poor quality of life (QOL). Early palliative care alongside standard oncologic care results in improved QOL and survival in some cancer types. The benefit in advanced pancreatic cancer (APC) is not fully quantified. METHODS: In this prospective case-crossover study, patients ≥ 18 years old with APC were recruited from ambulatory clinics at a tertiary cancer center. Patients underwent a palliative care consultation within 2 weeks of registration, with follow up visits every 2 weeks for the first month, then every 4 weeks until week 16, then as needed. The primary outcome was change in QOL between baseline (BL) and week 16, measured by Functional Assessment of Cancer Therapy - hepatobiliary (FACT-Hep). Secondary outcomes included symptom control (ESAS-r), depression, and anxiety (HADS, PHQ-9) at week 16. RESULTS: Of 40 patients, 25 (63%) were male, 28 (70%) had metastatic disease, 31 (78%) had ECOG performance status 0-1, 31 (78%) received chemotherapy. Median age was 70. Mean FACT-hep score at BL was 118.8, compared to 125.7 at week 16 (mean change 6.89, [95%CI (-1.69-15.6); p = 0.11]). On multivariable analysis, metastatic disease (mean change 15.3 [95%CI (5.3-25.2); p = 0.004]) and age < 70 (mean change 12.9 [95%CI (0.5-25.4); p = 0.04]) were associated with improved QOL. Patients with metastatic disease had significant improvement in symptom burden (mean change -7.4 [95%CI (-13.4 to -1.4); p = 0.02]). There was no difference in depression or anxiety from BL to week 16. CONCLUSION: Palliative care should be integrated early in the journey for patients with APC, as it can improve QOL and symptom burden. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT03837132.

AIMS: Opioid misuse and overuse have contributed to a widespread overdose crisis and many patients and physicians are considering medical cannabis to support opioid tapering and chronic pain control. Using a five-step modified Delphi process, we aimed to develop consensus-based recommendations on: 1) when and how to safely initiate and titrate cannabinoids in the presence of opioids, 2) when and how to safely taper opioids in the presence of cannabinoids and 3) how to monitor patients and evaluate outcomes when treating with opioids and cannabinoids. RESULTS: In patients with chronic pain taking opioids not reaching treatment goals, there was consensus that cannabinoids may be considered for patients experiencing or displaying opioid-related complications, despite psychological or physical interventions. There was consensus observed to initiate with a cannabidiol (CBD)-predominant oral extract in the daytime and consider adding tetrahydrocannabinol (THC). When adding THC, start with 0.5-3 mg, and increase by 1-2 mg once or twice weekly up to 30-40 mg/day. Initiate opioid tapering when the patient reports a minor/major improvement in function, seeks less as-needed medication to control pain and/or the cannabis dose has been optimised. The opioid tapering schedule may be 5%-10% of the morphine equivalent dose (MED) every 1 to 4 weeks. Clinical success could be defined by an improvement in function/quality of life, a ≥30% reduction in pain intensity, a ≥25% reduction in opioid dose, a reduction in opioid dose to <90 mg MED and/or reduction in opioid-related adverse events. CONCLUSIONS: This five-stage modified Delphi process led to the development of consensus-based recommendations surrounding the safe introduction and titration of cannabinoids in concert with tapering opioids.

INTRODUCTION: Chronic pain and co-occurring disorders, such as sleep disorders, anxiety, depression, post-traumatic stress disorder and substance use disorders, are among the most common conditions for which cannabis and cannabinoid-based products derived from the cannabis plant (CBP) are used for therapeutic purposes. However, healthcare providers report that they lack sufficient information on the risks, benefits and appropriate use of cannabis and CBP derived from the cannabis plant for therapeutic purposes. METHODS AND ANALYSIS: We will conduct a systematic review of studies investigating the use of cannabis and CBP derived from the cannabis plant for the treatment of chronic pain and co-occurring conditions. Randomised controlled trials, meta-analyses and observational studies will be prioritised. We will exclude reviews of cannabinoid mechanisms of actions, commentary articles and narrative reviews. The primary outcome of interest will be efficacy in relieving chronic pain. Secondary outcomes will be efficacy in ameliorating conditions such as sleep disorders, anxiety, depression, post-traumatic stress disorder and substance use disorders. We will search electronic bibliographic databases including Academic Search Complete, Cochrane Database of Systematic Reviews, Evidence based Medicine Reviewes, OVID Medline, PsychINFO, PubMed, CINAHL and Web of Science. Two reviewers will conduct screening and data collection independently. Study level of bias will be assessed using the Cochrane Risk of Bias Assessment Tool for randomised controlled trials and non-randomised studies. Narrative analysis will be utilised to interpret the data. ETHICS AND DISSEMINATION: The results of this systematic review will inform guideline development for the use of cannabis and CBP derived from the cannabis plant in the management of chronic pain and co-occurring conditions. Areas requiring further study will also be highlighted. PROSPERO REGISTRATION NUMBER: CRD42020135886.

BACKGROUND AND AIMS: To estimate prevalence of continuous use (persistence) of prescribed cannabinoid medications for up to 1 year from initial prescription in Manitoba, Canada and predictors of duration of use. DESIGN AND SETTING: A retrospective, population-based, cohort study using administrative data from the Manitoba Population Research Data Repository located at the Manitoba Centre for Health Policy, Canada. PARTICIPANTS: People without a record of a previous prescription who were prescribed a cannabinoid medication from 1 April 2004 to 1 April 2016 followed for 1 year from the date of first prescription. MEASUREMENTS: Continuous prescribed cannabinoid medication use was defined as use without a gap exceeding 60 days between prescriptions. The primary outcome was prevalence of continuous prescribed cannabinoid medication use for up to 1 year. A secondary outcome was duration of continuous use. Predictors were socio-demographic characteristics, medical diagnoses and type of cannabinoid medication. FINDINGS: Among 5452 new users, 18.1% [95% confidence interval (CI) = 17.08-19.12] were still using cannabinoids at 1 year. Median duration of use was 31 days [interquartile range (IQR) = 25-193]. This was highest for nabilone (33 days, IQR = 25-199) and lowest for nabiximols (20 days, IQR = 7-30). Use was longest among 19-45- and 46-64-year-old users and those with the highest socio-economic status. Fibromyalgia [hazard ratio (HR) = 0.89, 95% CI = 0.84-0.95], osteoarthritis (HR = 0.91, 95% CI = 0.82-0.97) and substance use disorder (HR = 0.85, 95% CI = 0.76-0.94) diagnoses were associated with longer use (HR for discontinuation-HR < 1 less discontinuation and longer use). A diagnosis of cancer was associated with shorter use (HR = 2.73, 95% CI = 2.02-3.67). CONCLUSIONS: In Manitoba, Canada approximately 18% of people prescribed cannabinoid medication continue using for at least 1 year. Duration of use varies with type of cannabinoid medication, age, socio-economic status and dagnosis.

BACKGROUND: Pharmaceutically derived cannabinoids are used for several indications, particularly pain management. The extent of their use from a population perspective is unknown; hence, the aim of this study was to evaluate trends in pharmaceutical cannabinoid use in Manitoba. METHODS: This was a retrospective population-based cross-sectional study using administrative data from the Manitoba Centre for Health Policy. Pharmaceutical cannabinoid users residing in Manitoba from Apr. 1, 2004, to Mar. 31, 2015 were identified. We assessed the annual prevalence and incidence of pharmaceutical cannabinoid use, and the sociodemographic characteristics and medical conditions of users. RESULTS: We identified 5181 people who received at least 1 prescription for a pharmaceutical cannabinoid over the study period, 5033 of whom received their first prescription after Apr. 1, 2004. Nabilone accounted for 73 650 (96.0%) of all prescriptions dispensed; dronabinol was discontinued during the study period. The annual prevalence rate of use increased by 527.2%, from 21.5 (95% confidence interval [CI] 21.4-21.6) users per 100 000 people in 2004/05 to 134.9 (95% CI 134.7-135.1) users per 100 000 people in 2014/15. The annual incidence rate increased by 413.3%, from 12.1 (95% CI 12.1-12.2) users per 100 000 person-years in 2004/05 to 62.2 (95% CI 62.1-62.4) users per 100 000 person-years in 2014/15. The highest use was among older adults aged 46-64 years, females and urban area residents. One-third of incident users (1775 [35.3%]) had a diagnosis of fibromyalgia in a 2-year period before their first cannabinoid prescription. General practitioners initiated almost half (2350 [46.7%]) of first prescriptions, and anesthesiologists/pain specialists initiated one-quarter (1299 [25.8%]). INTERPRETATION: The prevalence and incidence of pharmaceutical cannabinoid use increased over time. These findings provide insight into the use of cannabinoids before the introduction of recreational marijuana, which may affect this trend.
ABSTRACT
Pain and symptom control challenges are common in palliative care, and the search for other therapeutic strategies is ongoing. Unfortunately, patients and their caregivers are receiving little information or support from healthcare providers regarding the increasingly popular cannabinoid-based medicines (CBM). Clinicians, meanwhile, feel understandably perplexed by the discrepancy between the available evidence and the rapid interest in which patients and their families have demonstrated for CBM. There is an urgent need to address the many challenges that are delaying the appropriate integration of CBM into clinical practice, notwithstanding the obvious need for a solid general knowledge of pharmacology, mechanism of action and available clinical evidence supporting its use. The authors will address these challenges and provide practical recommendations regarding patient assessment for the use of CBM. The authors will also make suggestions regarding patient expectations in order to define clear objectives, review the necessary precautions prior to initiating treatment, aid in selecting the appropriate strain and route of administration as well as establishing proper titration and monitoring protocols. The authors will also discuss the lesser known but potentially therapeutic psychoactive effects of cannabis. As this class of therapeutic agents are likely to play a major role in palliative medicine in the near future, clinicians would benefit from familiarizing themselves with CBM and we can expect that patients and their caregivers will appreciate receiving support in their search for safe and effective therapeutic alternatives.

CONTEXT: Head and neck cancer patients with dysphagia frequently require tube feeding. Family members are often involved in caring for such patients but feel ill prepared to do so. Health professionals are in a key position to support family members who undertake caregiving responsibilities. The ability to provide support requires that the experiences of family caregivers (FCs) are well understood; however, few studies examining these experiences have been conducted. To address this gap, research is needed that examines and describes the caregiving experience from the perspective of family members themselves. Such work will provide an empirical base to guide health professionals' practice with FCs. OBJECTIVES: To explicate the lived experience of caring for a dysphagic relative with advanced head and neck cancer receiving tube feeding. METHODS: A descriptive phenomenological approach was used. Six FCs participated in two in-depth interviews each. Spiegelberg's three-step approach guided data analysis. RESULTS: The essence of FCs' experience was "negotiating a new normal" and includes the themes of 1) negotiating changing roles, 2) negotiating an altered lifestyle, 3) negotiating ways of coping, and 4) negotiating the meaning of the feeding tube. Themes 1 and 2 are reported on here. CONCLUSION: FCs experience significant challenges. Study findings provide direction for health professionals who work with FCs and underscore the need for future research geared toward developing and testing psychoeducational interventions aimed at supporting FCs in the important and difficult caregiving work they do.

PURPOSE/OBJECTIVES: To provide a preliminary determination of the prevalence rate of women who suffer from neuropathic pain post breast surgery (PPBS) and explore potential risk factors associated with its development. DESIGN: Prospective, quantitative, longitudinal survey. SETTING: Breast health clinic in western Canada. SAMPLE: A convenience sample of 17 women undergoing breast cancer surgery. METHODS: The Brief Pain Inventory was administered before surgery and 2 days, 10 days, and 3 months postsurgery. Demographic data also were collected preoperatively. Analysis included determining prevalence of PPBS; descriptive analyses on age, gender, and body mass index (BMI); presence of acute postoperative pain; type of surgery; and two-tailed t tests on age and BMI. MAIN RESEARCH VARIABLES: The symptom experience of chronic PPBS. FINDINGS: Twenty-three percent of the sample developed PPBS. Younger age (50 years or younger), more invasive surgery, acute postoperative pain, and less analgesic use during the acute postoperative period were factors associated with the development of PPBS. CONCLUSIONS: Additional research is required to confirm the significance of these potential risk factors in the development of PPBS. IMPLICATIONS FOR NURSING: Nurses are ideally situated to identify early signs of PPBS. In addition, nurses play a key role in the education of patients and healthcare professionals and can facilitate increased awareness about the possibility of developing PPBS, enabling earlier and more effective treatment of PPBS.

Chemotherapy-induced nausea and vomiting (CINV) in cancer patients places a significant burden on patients' function and quality of life, their families and caregivers, and healthcare providers. Despite the advances in preventing CINV, a substantial proportion of patients experience persistent nausea and vomiting. Nabilone, a cannabinoid, recently received Food and Drug Administration approval for the treatment of the nausea and vomiting in patients receiving cancer chemotherapy who fail to achieve adequate relief from conventional treatments. The cannabinoids exert antiemetic effects via agonism of cannabinoid receptors (CB1 and CB2). Clinical trials have demonstrated the benefits of nabilone in cancer chemotherapy patients. Use of the agent is optimized with judicious dosing and selection of patients.
ABSTRACT
Both conceptual and empirical evidence in the caregiving literature suggest that "how" informal caregivers are prompted to think about patient experiences can impact their ability to achieve perceptual agreement with patients on symptom events. Researchers have begun to test the effects of different clinical questions with caregivers or a proxy on their perceptual agreement with patient self-reports. However, there are gaps in understanding caregivers' underlying thoughts and feelings when they are prompted to take different vantage points on the patient's symptom experiences. To assess these thoughts and feelings, content analysis was performed on verbal responses to an open-ended interview schedule, in which caregivers were questioned about their thoughts and feelings in one of three randomly assigned instructional conditions-neutral, imagine-patient, and imagine-self perspective-taking. Responses were classified into one of five cue categories: patient-oriented, caregiver-oriented, generalized other, feeling distanced, and other. Caregivers tended to respond to patient symptom experiences in ways that suggest it is innate for caregivers in intimate relationships to make an effort to imagine the patient's viewpoint on symptom events. When caregivers were prompted to imagine the patient's perspective, "labeling" processes were also triggered that denote a categorization process in which caregivers interpreted the meaning of simple patient information arising in the care situation. A large portion of caregivers in the neutral and imagine-patient conditions reported feeling distanced from patients in light of perceived communication difficulties.

Recent conceptual work on multiple proxy perspectives indicates that clinicians should be more reflective in terms of how they question or prompt informal caregivers to report on patient illness experiences. There are different ways in which therapeutic questions might be posed that can influence perceptual agreement between patients and caregivers. The purpose of this randomized, between-subjects study was to test the hypothesis that "The interrater gap between patient self-assessment and caregiver assessment on patient multidimensional symptom experiences will be reduced when caregivers are prompted to imagine-patient perspective-take." We also tested the hypothesis that "Regardless of the perspective-taking prompt provided to the caregiver, gender will have no impact on patient and caregiver discrepancy scores on patient symptom experiences." This study comprised a convenience sample of 126 dyads consisting of breast and prostate cancer patients, and their informal caregivers. Patients provided self-reports on the abbreviated Memorial Symptom Assessment Scale (MSAS). Informal caregivers also completed the abbreviated MSAS under one of three randomly assigned instructional set conditions: neutral, imagine-patient perspective-taking, and imagine-self perspective-taking. The imagine-patient prompt was effective in reducing caregiver discrepancy across symptoms and underlying dimensions in comparison to the imagine-self prompt. However, the least discrepancy between patients and caregivers occurred in the neutral condition. The greatest discrepancy by caregivers occurred in imagine-self condition. For the most part, there was no significant interaction effect between caregiver gender and induced perspective-taking across each of the symptoms and underlying frequency, severity, and distress. These results lend support for Pickard and Knight's multiple proxy perspectives model in that different perspective-taking prompts can result in varying levels of perceptual agreement, of which clinicians need to be aware to deliver sensitive patient and family centered care.

INTRODUCTION: The cannabinoids nabilone (Cesamet) and dronabinol (Marinol) are indicated for the management of chemotherapy-induced nausea and vomiting (CINV) in cancer patients who have failed to respond adequately to conventional antiemetic therapy. DISCUSSION: The endocannabinoid (CB) system interacts with numerous other systems and pharmaceutical cannabinoids target ubiquitous CB1 and CB2 receptors in the central nervous system and periphery, relieving nausea and vomiting and pain. SUMMARY: The benefits of this novel class of medications in cancer may extend beyond CINV, as indicated by data from preclinical studies and animal models.

Patients with advanced illnesses suffer from a myriad of distressing symptoms. Palliative care aims to alleviate the distress caused by such symptoms. In extreme circumstances palliative sedation may be implemented to manage symptom distress that is not responsive to standard treatment modalities. Nurses are involved in the care of patients receiving palliative sedation as well as their families. To date, however, little research has been conducted examining the nurses' experiences with, and perceptions about the use of palliative sedation in end-of-life care. In order to redress this gap in the literature a descriptive-exploratory study guided by the theory of symbolic interactionism was conducted. Face-to-face interviews were conducted with 10 nurses working on an adult in-patient palliative care unit within a long-term care facility in Canada. The major theme emerging from content analysis of interview transcripts was that of 'Working your way through the quagmire'. The metaphor of the quagmire captured the difficult and complex issues nurses grappled with in instances where palliative sedation was used, and integrates the major categories into the key analytic model emerging from this study.

AIM: This paper reports the findings of a study that generated a conceptual model of the nursing behaviours and social processes inherent in the provision of quality end-of-life care from the perspective of nurses working in an acute care setting. BACKGROUND: The majority of research examining the issue of quality end-of-life care has focused on the perspectives of patients, family members and physicians. The perspective of nurses has generally received minimal research attention, with the exception of those working within palliative or critical care. The vast majority of hospitalized patients, however, continue to be cared for and die on medical units. To date, little research has been conducted examining definitions and determinants of quality end-of-life care from the perspective of nurses working in acute adult medical settings. METHOD: Grounded theory method was used in this study of 10 nurses working on acute medical units at two tertiary university-affiliated hospitals in central Canada. Data were collected during 2002 by interview and participant observation. FINDINGS: The basic social problem uncovered in the data was that of nurses striving to provide high quality end-of-life care on an acute medical unit while being pulled in all directions. The unifying theme of 'Creating a haven for safe passage' integrated the major sub-processes into the key analytic model in this study. 'Creating a haven for safe passage' represents a continuum of behaviours and strategies, and includes the sub-processes of 'facilitating and maintain a lane change'; 'getting what's needed'; 'being there'; and 'manipulating the care environment'. CONCLUSION: The ability of nurses to provide quality end-of-life care on an acute medical unit is a complex process involving many factors related to the patient, family, healthcare providers and the context in which the provision of end-of-life care takes place.

This paper describes the results of a Web survey on the use of personal digital assistants (PDAs) by physicians across Canada involved with the delivery of palliative medicine in different settings. Seventy-two physicians responded to the survey from April to July 2005. The survey revealed 58.3% of respondents currently use PDAs on a daily basis, mostly to organize their practice and to look up medical references. Some use their PDAs to store patient information and to access a central electronic patient record (EPR). In terms of potential PDA use in palliative medicine, six thematic areas are suggested: medical references, EPR, staying connected, personal productivity, clinical research, and issues/concerns. For implications, healthcare organizations should consider mobile technology as part of their information systems strategy. The feasibility of a portable EPR for palliative medicine should be explored, and an information-based approach can help advance palliative medicine research in Canada.
