Do Physician Recommendations for Colorectal Cancer Screening Differ by Patient Age?
Bibliographic record
Abstract
Colorectal cancer screening is underutilized, resulting in preventable morbidity and mortality. In the present study, age-related and other disparities associated with physicians' delivery of colorectal cancer screening recommendations were examined. The present cross-sectional study included 43 physicians and 618 of their patients, aged 50 to 80 years, without past or present colorectal cancer. Of the 285 screen-eligible patients, 45% received a recommendation. Multivariate analyses revealed that, compared with younger nondepressed patients, older depressed patients were less likely to receive fecal occult blood test recommendations, compared with no recommendation (OR=0.31, 95% CI 0.09 to 1.02), as well as less likely to receive colonoscopy recommendations, compared with no recommendation (OR=0.14; 95% CI 0.03 to 0.66). Comorbidity and marital status were associated with delivery of fecal occult blood test and colonoscopy recommendations, respectively, compared with no recommendation. In summary, patient age and other characteristics appeared to influence physicians' delivery of colorectal cancer screening and choice of modality.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
