Cost Effectiveness of Mailed Outreach Programs for Colorectal Cancer Screening: Analysis of a Pragmatic, Randomized Trial
Clinical guidelines for colorectal cancer (CRC) screening suggest use of either stool-based tests or colonoscopy. We conducted a cost-effectiveness analysis to compare 2 mailed outreach strategies to increase CRC screening.

Too Good to Be True? Evaluation of Colonoscopy Sensitivity Assumptions Used in Policy Models
This paper examines the validity of the CRC-SPIN model and colonoscopy sensitivity assumptions. We find that colonoscopy may be less accurate than currently assumed, especially for diminutive adenomas.

Cost-Effectiveness of Community-to-Clinic Tailored Navigation for Colorectal Cancer Screening in an Underserved Population: Economic Evaluation Alongside a Group-Randomized Trial
Adding community-to-clinic tailored navigation to a community-based colorectal cancer screening promotion program may be highly cost-effective.

Black and White Differences in Colorectal Cancer Screening and Screening Outcomes: A Narrative Review
Higher rates of colorectal cancer incidence among black patients are primarily driven by lower rates of colorectal cancer screening. Our findings highlight the need to increase black patients' access to quality screening to reduce colorectal cancer incidence and mortality.

Use of Common Cancer Screenings Rebounded Quickly After Dropping at Start of the Pandemic
Screenings for breast cancer and colon cancer dropped dramatically during the early months of the coronavirus pandemic, but use of the procedures returned to near-normal levels by the end of July 2020.

Association of Primary and Specialty Care Integration on Physician Communication and Cancer Screening in Safety-Net Clinics
This study aimed to describe strategies CHCs use to integrate care with specialists and examine whether more strongly integrated CHCs have higher rates of screening for colorectal and cervical cancers and report better communication with specialists.

Effect of Time to Diagnostic Testing for Breast, Cervical, and Colorectal Cancer Screening Abnormalities on Screening Efficacy: A Modeling Study
Even relatively small delays in diagnostic testing after an abnormal cancer screening test can reduce screening effectiveness, though the impact varies by cancer type.

Accounting for Misclassification in Electronic Health Records-derived Exposures Using Generalized Linear Finite Mixture Models
Exposures derived from EHRs may be misclassified, leading to biased estimates of their association with outcomes of interest: finite mixture models can correct biases with no loss of efficiency.

Follow-up of Positive Fecal Test Results: Sooner Is Better, but How Much Better?
Patients prefer less invasive approaches such as fecal immunochemical test (FIT) for colorectal cancer screening, but the effectiveness of FIT depends on annual screenings for those with negative test results and colonoscopy if FIT tests are positive.

Association Between Primary Care Visits and Colorectal Cancer Screening Outcomes in the Era of Population Health Outreach
Patients who visited their primary care provider one or more times were almost twice as likely to be screened for colorectal cancer and about 30 percent more likely receive a follow-up colonoscopy after a positive screening result.

Estimation of Benefits, Burden, and Harms of Colorectal Cancer Screening Strategies: Modeling Study for the US Preventive Services Task Force
Comparative modeling of colorectal cancer screening methods for previously unscreened adults found that the use of four strategies over different intervals between the ages of 50 and 75 years yielded a comparable balance of benefit and burden.
