Systematic review and meta-study synthesis of qualitative studies evaluating facilitators and barriers to participation in colorectal cancer screening
A partir d'une revue systématique de la littérature publiée jusqu'en février 2015 (94 études), cette étude identifie les facteurs favorisant ou entravant la participation au dépistage du cancer colorectal
Screening reduces the incidence, morbidity and mortality of colorectal cancer (CRC) yet participation tends to be low. We undertook a systematic review and meta-study synthesis of qualitative studies to identify facilitators and barriers to CRC screening participation. We searched major bibliographic databases for records published in all languages from inception to February 2015. Included primary studies that elicited views and perceptions towards CRC screening were appraised for relevance and quality. We used a two-stage synthesis to create an interpretation of CRC screening decisions grounded in primary studies; a thematic analysis to group themes and systematically compare studies and a meta-synthesis to generate an expanded theory of CRC screening participation. 94 studies were included. The decision to participate in CRC screening depended on an individual's awareness of CRC screening. Awareness affected views of cancer, attitudes towards CRC screening modalities, and motivation for screening. Factors mediating awareness included public education to address misconceptions, primary care physician (PCP) efforts to recommend screening, and the influence of friends and family. Specific barriers to participation in populations with lower participation rates included language barriers, logistical challenges to attending screening tests, and cultural beliefs. This study identifies key barriers, facilitators, and mediators to CRC screening participation.
