State of the Science: Health Care Provider Communication of Cannabis Use Among Adults Living with Cancer

Abstract

Despite medicinal cannabis gaining popularity for managing symptoms in cancer patients, a knowledge gap exists in patient-provider communication crucial for monitoring outcomes, optimizing dosing, and educating healthcare providers to integrate cannabis into treatment plans. Our goal is to understand communication dynamics, identify gaps, and pave the way for effective cannabis communication for individuals living with cancer (PLWC). We searched PubMed, CINAHL, and EBSCO for articles published between 2013 and July 2023, capturing the key concepts of cannabis use in cancer patients and their communication with healthcare providers in oncology settings. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guided the review. Studies were appraised by applying the Johns Hopkins Evidence-Based Practice Model for Nursing and Healthcare Professionals. Of the 2384 articles reviewed, 14 met the inclusion criteria. Three were qualitative studies, and 11 were cross-sectional surveys. All studies were level III evidence. Studies captured patients’ and providers’ perspectives; five were conducted among cancer patients, and nine were among healthcare providers in oncology settings. Findings revealed variations in healthcare provider recommendations, patient-initiated discussions, and barriers to discussing medical cannabis (MC). The synthesis of this evidence highlights the complexities surrounding MC in oncology settings, including knowledge gaps among healthcare providers, patient-initiated discussions, and challenges in accessing and prescribing medicinal cannabis. This review contributes valuable insights into the current landscape of MC use in cancer care, emphasizing the need for improved communication, education, and support for both patients and healthcare providers.
