The objective of this study was to evaluate the effects of data-source and adjudication on indication classification and on estimates of the effectiveness of screening colonoscopy on late-stage colorectal cancer diagnosis risk.
We also found fair-to-good agreement between adjudication and algorithm-based indication classification for each data source alone (78.8-87.6%, ĸ = 0.56-0.72), but very good agreement for all sources combined (93.0%, ĸ = 0.86).
After independent review, data extraction was compared, disagreement of coding and classification was resolved by consensus or third party adjudication (CK, MRK, or GMA), and overall agreement was calculated.
In our study, we found no single gold-standard source of information in the medical records for indication classification that agreed consistently with expert adjudication, and the data sources were complementary in achieving better indication classification.
Future larger studies in non-managed care settings and in different settings or populations are needed to establish the benefits of obtaining data from multiple sources and conducting adjudication for indication classification.

The primary objective was to compare CRP and PCT values in the four different categories of CAP level of certainty using the day-28 adjudication committee classification.
However, the lack of statistically significant differences in the mean CRP and PCT values in the definite CAP cases, whether or not these biomarkers were available for the adjudication committee, argues against a major impact of these results on adjudication committee classification.
We evaluated indication classification concordance before and after adjudication and used logistic regressions with the Wald Chi-square test to compare estimates of the effects of screening colonoscopy on late-stage colorectal cancer diagnosis risk for each of our data sources to the adjudicated indication.
