Experience and satisfaction of participants in colorectal cancer screening programs : a qualitative evidence synthesis

Background: Experience and satisfaction of colorectal cancer screening program participants are among the key factors that determine adherence to these programs. Understanding them is crucial to ensure future participation. Objectives: To explore and gain understanding on the experience and satisfaction of the average-risk population participating in colorectal cancer screening programs. Methods: A Qualitative Evidence Synthesis. We conducted a literature search up to April 2023 in Medline, Embase, CINAHL, PsycINFO and ProQuest Dissertations and Thesis. We independently selected the studies for their inclusion, assessed their methodological quality (with CASP tool) and extracted data. Disagreements were solved by consensus. We thoroughly read the selected studies, and analyzed the data following a thematic synthesis approach. We evaluated the confidence in our findings with CERQUAL. Results: We included six studies: four had an appropriate quality, and two had some methodological limitations. We identified five main findings across studies: (1) Variability in the concerns about the results; (2) Challenges regarding procedure logistics; (3) Care received from the healthcare professionals; (4) Being adequately informed; (5) Expectations and experience with the program. All findings had a moderate level of confidence. Conclusions: Our qualitative review provides a picture of the experience and satisfaction of the average-risk population participating in colorectal cancer screening programs. Despite some logistical and expectation management issues, the overall satisfaction with the programs is high. More research is needed on the topic, as there are still important gaps in knowledge.
