RESUMO
We intend for this article to provide a foundation toward the creation of a more patient-centric approach to the informed consent process. Our overall objectives are to promote ethical clinical research standards and procedures toward enhanced supportive systems for clinical trial participants. We provide a suggested format which multidisciplinary clinical trial researchers can adapt for their own clinical trial setting.
RESUMO
BACKGROUND: Diet is associated with colorectal cancer survival. Yet, adherence to nutrition guidelines is low among colorectal cancer survivors. METHODS: We conducted a pilot trial among colorectal cancer survivors to evaluate a 12-week remote dietary intervention. Participants received print materials and were randomized (1:1) to intervention (website, text messages) or wait-list control. Primary outcomes included feasibility and acceptability. We also explored change in diet from 0 to 12 and 24 weeks and change from 0 to 12 weeks in anthropometry and circulating biomarkers (Trial Registration: NCT02965521). RESULTS: We randomized 50 colorectal cancer survivors (25 intervention, 25 control). Retention was 90% at 12 weeks and 84% at 24 weeks. Participants had a median age of 55 years and were 66% female, 70% non-Hispanic white, and 96% had a college degree. The intervention arm responded to a median 15 (71%) of 21 text messages that asked for a reply [interquartile range (IQR) = 8, 19] and visited the website a median of 13 (15%) days (IQR = 1, 33) of the 84 study days. CONCLUSIONS: We developed a Web-based dietary intervention for colorectal cancer survivors. Our pilot results suggest that colorectal cancer survivors may engage more with text messages than a study website. Research to improve tailoring of text messages, while maintaining scalability, is needed. IMPACT: Remote dietary interventions using text messages may be feasible for colorectal cancer survivors.See all articles in this CEBP Focus section, "Modernizing Population Science."
