CT Colonography Registry

The CTC registry provides evidence-based health outcomes and process data for decision-making purposes. The registry allows facilities to compare results to regional and national benchmarks for quality improvement.

Process measures include rate of adequacy of diagnostic CTC examination and rate of adequacy of screening CTC examination. Outcome measures include rate of colonic perforation, true positive rate and extracolonic findings.

Participating facilities and physicians receive quarterly reports based on aggregated benchmarks to facilitate patient safety and quality improvement efforts.

The CTC registry offers participants additional ways to fulfill reporting requirements for the Merit-based Incentive Payment System (MIPS). Participation also allows credit for Maintenance of Certification (MOC) Part IV requirements of the American Board of Radiology (ABR).

Announcement: CTC Registry Publication Shows Access Barriers Related to Medicare Noncoverage: A new study, based on data from the CT Colonography Registry, concludes the number of screening CTC exams decreased after age 65. This is likely due, at least in part, to lack of Medicare coverage. The study, published in the JACR, also indicates a large impact on minority patients. Read the full study
