We developed a point-of-care tool indicating risk categories for colorectal cancer (CRC) based on family history (FH) and management recommendations tailored to risk. The study objective was to determine if this CRC Risk Triage/Management Too would enable family physicians (FPs) to appropriately triage and make screening and genetics referral recommendations for patients with CRC FH. Baseline questionnaires were mailed to a random sample of FPs in Ontario and Newfoundland, Canada. Participants were asked to use the tool for 3 months and then complete a follow-up questionnaire. The primary outcomes were correct responses to questions regarding CRC risk category, screening method, starting age, frequency, and decision to refer to genetics, for eight clinical vignettes. The study was completed by 75/121 (62 %) participating FPs. Most (77 %) agreed they routinely recommended fecal occult blood testing for average risk patients age ≥50. This did not change significantly following the intervention. There was a significant increase in confidence in CRC risk assessment (52 % pre; 88 % post; p < 0.001), correct management recommendations for patients with CRC FH (51 % pre; 84 % post; p < 0.001), and improvement in total mean scores on outcome measures for all vignettes. Most (90 %) agreed the tool would improve practice. Receipt of the CRC Risk Triage/Management Tool was associated with improvement in FPs' CRC risk assessment, screening, and genetics referral recommendations for clinical vignettes. This demonstrates the value of point-of-care tools and illustrates a process for development, evaluation, and dissemination of tools needed by FPs if potential impacts of genomic advances are to be achieved.
