title: Linked claims and medical records for cancer case management : evaluation of mammography abnormalities.
abstract: BACKGROUND
  Failure to obtain the requisite follow-up of patients with abnormal mammograms may delay cancer diagnosis and impact outcome. Up to 20% of women do not receive timely recommended follow-up. The current study tested the accuracy of the linkage of payer claims and clinical data to identify the appropriate treatment for patients with abnormal mammograms.
  
  
  METHODS
  Electronic medical records in a staff model practice that was affiliated with a single health payer were scanned to identify the Breast Imaging Reporting and Data System (BI-RADS(R)) code for all mammograms. For each woman with a BI-RADS code 0, 3, 4, or 5 mammogram, the payer claims were searched for follow-up breast procedures (imaging, biopsy, and surgery) occurring within 2 months for BI-RADS code 0, 4, and 5 mammograms and within 8 months for BI-RADS code 3 mammograms. For women with >1 abnormal mammogram during the study period, only follow-up for the first abnormal mammogram was examined. The medical records of cases defined by claims as not having recommended follow-up care were reviewed to determine the accuracy of claims analyses.
  
  
  RESULTS
  A total of 17,329 women underwent 23,721 mammograms between January 1, 2001 and December 31, 2003. BI-RADS codes 0, 3, 4, or 5 occurred in 1,490 mammograms (6.3%). Among 1,206 women with a first abnormal mammogram who were eligible for claims follow-up, 16% did not receive recommended follow-up care. Medical record review demonstrated that the claims search accurately identified follow-up care in 97% of these cases.
  
  
  CONCLUSIONS
  Administrative claims supplemented with BI-RADS data were found to accurately identify the follow-up care of patients with abnormal mammograms. Case management using this method may assist physicians in ensuring that all patients receive appropriate care.
