Background And ObjectiveAlthough up to 85% of patients with cancer use complementary and alternative medicine (CAM), they commonly do not disclose this information to their healthcare providers. Cancer-related pain (CRP) is one of the most common symptoms among those who may seek CAM. This study was conducted to identify the quantity and assess the quality of CAM recommendations across clinical practice guidelines (CPGs) for the treatment and/or management of CRP, as this has not been explored in the literature.MethodsA systematic review was conducted to identify cancer pain CPGs. MEDLINE, EMBASE, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched from 2009 to 2020. The Guideline International Network and the National Centre for Complementary and Integrative Health websites were also searched. Eligible CPGs on CRP in adults were assessed using the Appraisal of Guidelines, Research and Evaluation II (AGREE II) instrument.ResultsOf 771 unique search results, 13 mentioned CAM and 11 made CAM recommendations. Eligible CPGs were published in 2009 or later and focused on the treatment/management of CRP. Scaled domain percentages from highest to lowest ranged from (overall, CAM): 88.1%, 88.1% (for scope and purpose) to 21.0%, 8.5% (for applicability). Quality varied within and across CPGs. One CPG was recommended by both appraisers; 6 were recommended as "Yes" or "Yes with modifications."ConclusionsThe present study has identified and summarized a number of CPGs that clinicians may consult to understand what CAMs are recommended in the context of the treatment and/or management of CRP.© 2020 World Institute of Pain.
