Introduction: Colorectal cancer (CRC) is the 2nd leading cause of cancer deaths worldwide. Colonoscopy has been deemed the gold standard of CRC screening, yet many other tests remain available. Lack of knowledge regarding CRC screening tests has been a theme amongst individuals, and patient decision aids (PDAs) may address this gap. The International Patient Decision Aid Standards Collaboration (IPDAS) has worked to enhance the quality of PDAs, as their use may increase equitable access to health related information. The aim of this review was to understand the current state of PDAs to facilitate informed decision-making for CRC screening, focusing on whether PDAs are available to help patients decide which CRC screening test to use.



Methods: A review was conducted utilizing PubMed. Search terms included but were not limited to decision aid, decision support techniques, colorectal neoplasms, screening, and early diagnosis. This search strategy returned 79 studies published from 2005-2021. Studies that did not mention or include a PDA were eliminated from evaluation, leaving 24 studies for analysis. Articles were evaluated based on PDA objective, delivery method (e.g.: online, paper, DVD), endorsement of following IPDAS criteria, and availability of the PDA. Data was then quantified to determine relative percentages of each criterion.

Results: Overall, 50% of publications stated their primary objective was promotion of CRC screening participation. CRC screening test selection comprised 8% of the objectives stated by authors. The most common method of deliverance was through a web-based module, with paper, DVD, booklet, iPad, and both paper + web-based cited less commonly. Only 12% of articles freely shared their PDA, and 29% of articles shared incomplete versions of their PDA. A total of 33% of articles mentioned following IPDAS criteria; however, none of these were created for selecting a specific CRC screening test. Only half of the articles that mentioned following IPDAS criteria were published during or after the most recent IPDAS guideline update in 2018, and only two articles were published after the most recent USPSTF CRC screening guidelines published in 2021.



Discussion: There is a clear deficit of PDAs created following IPDAS criteria to assist patients in selecting a specific CRC screening test. The new USPSTF CRC screening guidelines and updated IPDAS criteria provide an impetus for the development of specific PDAs to benefit patients in their decision-making related to CRC screening.
