Development of a Practical Model for Targeting Patient Decision Support Interventions to Promote Colorectal Cancer Screening in Vulnerable Populations

We sought to develop a practical model for predicting probability of colorectal cancer (CRC) screening completion in a diverse safety-net population and a subsequent framework for targeting screening promotion interventions. Data used to construct the models was prospectively collected from a CRC screening intervention. Models were cross-validated by randomly splitting the data into training and validation samples. The predicted probabilities of screening completion from the final model were trichotomized into framework groups and cross-validated by defining cut-points in the training sample, applying them to the validation sample, and comparing across samples for homogeneity. The final model included demographic and simple psychosocial measures and predicted screening behavior adequately (AUROC=0.63). The framework groups (cut-points 0.62 (low), 0.74 (medium), and 1.0 (high)) were homogeneous across the two samples. The model and framework may be useful for designing and delivering targeted interventions to promote CRC screening. Future research should validate the framework groups

A Cost-Utility Analysis of Ablative Therapy for Barrett's Esophagus

Recommendations for patients with Barrett’s esophagus (BE) include endoscopic surveillance with esophagectomy for early-stage cancer, although new technologies to ablate dysplasia and metaplasia are available. This study compares the cost-utility of ablation with that of endoscopic surveillance strategies

Adherence to Competing Strategies for Colorectal Cancer Screening Over 3 Years

We have shown that, in a randomized trial comparing adherence to different colorectal cancer (CRC) screening strategies, participants assigned to either fecal occult blood testing (FOBT) or given a choice between FOBT and colonoscopy had significantly higher adherence than those assigned to colonoscopy during the first year. However, how adherence to screening changes over time is unknown
