Risk and reluctance: understanding impediments to colorectal cancer screening

Abstract

Purpose: Screening to detect and prevent colorectal cancer (CRC) is well below optimal, contributing to needless CRC-related morbidity and mortality. Little detailed information exists explaining why screening technologies are underutilized and why screening adherence rates are low. Prior to the design of an intervention study, we assessed knowledge about CRC among adult women and men with access to health care. We also investigated patterns of perceived risk for CRC, barriers and facilitators to screening, and experience and intentions with regard to both fecal occult blood testing and flexible sigmoidoscopy.

Methods: We analyzed data from semistructured focus group interviews with a small, nonrepresentative sample (n = 39) of community-dwelling adult men and women ages 50 to 64 and 65 plus.

Results: CRC-related knowledge is low, and misperceptions are common. Provider practices reinforce low levels of perceived risk. Multiple barriers to screening exist, of which many are remediable.

Conclusions: We are at an early stage in the diffusion of information about CRC. Screening utilization may be improved through development of appropriate public health awareness campaigns and by addressing service factors. Recommendations are provided.
