The National Center for Health Statistics conducts the National Health Care Surveys. Each survey targets a specific care setting. The data from these surveys must be weighted, sampled, and analyzed in order to provide information to support health care policy makers, public health professionals, and researchers.
Karna provides senior statistical programming support to NCHS, including weighting survey data, sampling, and producing national estimates and variances. This requires expert knowledge in the underlying coding standards, including HL7, SNOMED, LOINC, CPT, ICD-9, ICD-10, CDA, CDA IG, and RX NORM. Our team uses SAS, SQL, Java, XML, and Schematron tools to accomplish the work.
The result of this effort are data files and specification documents that allow the survey data to be available, including the NCHS Data Online Query System (DOQS), Healthy People 2020 (HP2020), the Health Indicators Warehouse (HIW), the Web-Based Injury Statistics Query and Reporting System (WISQARS), and the Wide-ranging Online Data for Epidemiologic Research (CDC WONDER).
