Almost a decade has passed since the American Society of Clinical Oncology (ASCO) Choosing Wisely campaign identified costly diagnostic testing, radiographic imaging, and therapies that are routinely utilized in cancer care despite lacking evidence of benefit. We sought to evaluate the impact of ASCO Choosing Wisely guidelines and to identify barriers to and facilitators of guideline adherence. Methods: A systematic review of published literature from 2012-2021 was performed in accordance with PRISMA guidelines on the trend in use of low value oncology care. All ten of ASCO Choosing Wisely Guidelines were selected for inclusion; these included recommendations focused on cancer screening, staging and surveillance imaging, and systemic treatment and support. The following databases were searched for original research based in the United States: PubMed, CINAHL, Embase, Web of Science, Scopus, and ASCO Meeting abstracts. Eligible studies were examined for information on design, population, and study outcomes, which included guideline adherence and facilitators and barriers to implementation. All citations were independently dual-screened in a blinded fashion by authors (AG, MS). Results: 35 independent studies were identified from 3,590 unique citations and included n = 1,130,216 patients. Data sources captured large claims database analyses (13 studies, n = 1,069,289), institutional studies (14 studies, n = 53,358), patient-reported surveys (2 studies, n = 915), and interventional studies (6 studies, n = 6654). Adherence to ASCO Choosing Wisely guidelines ranged from 13% to 100% overall. Use of low value oncology care varied depending on the area of recommendation, such as cancer screening (44% to 77%), staging and surveillance imaging (30% to 100%), and systemic treatment and support (13% to 100%). Adherence was facilitated by: (a) physician awareness of and education around the recommendations; (b) patient engagement; (c) embedded EHR best practice alerts; (d) guideline alignment with insurance payer requirements; and (e) integrated healthcare systems. Barriers to guideline incorporation included perceived patient anxiety and concerns about patient satisfaction; illness-specific practices; and time needed for patient-provider conversations regarding low value care. Conclusions: Adherence to the ASCO Choosing Wisely guidelines is variable across the cancer care continuum. Health system and policy-level interventions are needed to further reduce the overuse of low value care in oncology.
