Estimation of National Colorectal-Cancer Incidence Using Claims Databases

Table 3

Algorithm 2 results in Côte d’Or by diagnostic year: sensitivity and positive predictive value of administrative data for identifying incident colorectal-cancer cases versus cancer registries used as the gold standard.

Year	Incident cases identified by Algorithm 2	Administrative data/registry discordances		Sensitivity (%) (95%CI)	PPV (%) (95%CI)
		False positives	False negatives
2004	457	180	55	83.4 (79.4–87.4)	60.6 (56.1–65.1)
2005	465	191	39	87.5 (83.8–91.2)	58.9 (54.4–63.4)
