Summary
Colorectal cancer screening quality varied. While cecal intubation and adenoma detection rates were good, follow-up of positive fecal occult blood tests and colonoscopy reporting need improvement for better screening quality.
Area of Science:
- Public Health
- Gastroenterology
- Cancer Screening
Background:
- Community colorectal cancer screening quality has documented gaps.
- The Colorectal Cancer Screening Demonstration Program (CRCSDP) provided services from 2005-2009 to underserved populations.
- The study evaluated screening quality indicators within the CRCSDP.
Purpose of the Study:
- To assess the quality of colorectal cancer screening within the CRCSDP.
- To identify areas for improvement in screening and diagnostic services.
Main Methods:
- Collected standardized clinical data for screened individuals.
- Analyzed data on client demographics, screening history, risk, test results, and follow-up.
- Evaluated colonoscopy-specific quality metrics like cecal intubation and polyp removal.
Main Results:
- 53% of fecal occult blood tests (FOBTs) were completed and returned.
- Follow-up colonoscopy rates after positive FOBTs were 77% and 97% at two sites.
- Cecal intubation rates ranged from 90%-98%; adenoma detection rates were 32% (men) and 21% (women).
- Colonoscopy reporting lacked detail on bowel preparation and polyp removal completeness in some cases.
Conclusions:
- Cecal intubation and adenoma detection rates met recommended standards.
- Improvements are needed in FOBT follow-up, colonoscopy reporting, and rescreening interval recommendations.
- Continuous monitoring of quality indicators is crucial for enhancing colorectal cancer screening quality.
