Merging these datasets enhances the reliable identification of oncologic surgeries; extends methodological confidence for using linked.
Observational (n=149,970)
Effect estimate: kappa 0.70-0.90
SEER and Medicare data show good agreement for major surgical procedures, and combining both sources enhances the identification of cancer-directed surgeries.
Cooper et al. (2002) conducted an observational in Breast, colorectal, endometrial, lung, pancreatic, and prostate cancer (n=149,970). Medicare claims data (inpatient, physician, and outpatient) vs. SEER files was evaluated on Agreement between SEER and Medicare files for measuring cancer-related surgery (kappa 0.70-0.90). Agreement between Medicare claims and SEER data for identifying major cancer-directed surgical procedures was high (kappa 0.70-0.90).
