Abstract:	The National Center for Health Statistics (NCHS) has developed an administrative records linkage program designed to enhance the usefulness of its major data collection systems. Currently, large population surveys such as the National Health Interview Survey and the National Health and Nutrition Examination Surveys are linked to death certificate records, Social Security Administration disability determination and payment records, and Centers for Medicare and Medicaid Services Medicare payment and utilization records. These data linkages provide the opportunity to conduct research on a wide variety of health outcomes that would not be otherwise possible. Evaluation studies are conducted to examine the validity of the probabilistic matching algorithms used to conduct the linkages and to identify any bias in the resultant data files. Linked data are reviewed for disclosure risk. Data items determined to increase respondent reidentification are made available only through the NCHS secure data center. This presentation provides an overview of NCHS' data linkage practices, evaluation studies, data release procedures, and available linked data products.
