Using Data from NCHS: An Overview of NCHS Data Access Tools Monitoring the Public's Health: Using Data from the National Center for Health Statistics APHAContinuing Education Institute: Session 1007.0November 4, 2006 Ann Aikin
Accessing NCHS Data: Kinds of Tools Interactive Data Tables (Powered by Beyond 20/20) Online Queries (Simple) • Healthy People DATA2010 • CDC WONDER • WISQARS • Office on Women's Health’s Quick Health Data Online • National Survey of Children with Special Health Care Needsand National Survey of Children’s Health(SLAITS) • Health Data for All Ages • Trends in Health and Aging • VitalStats: Coming Soon!
Accessing NCHS Data: Kinds of Tools…(Continued) Complex queries: Data Set Access • Statistical Export and Tabulation System (SETS) • DataFerrett • Inter-university Consortium for Political and Social Research (ICPSR)
Using Health Insurance Data: Non-Tools Data are released from NHIS and others • In ASCII (raw data files—you need your own statistical package to use, like SAS, SPSS, or STATA) • On the Internet, as an Early Release • In publications, such as Health, United States
Early Release of Selected Estimates Based on Data From the January-March 2006 National Health Interview Survey From: http://www.cdc.gov/nchs/about/major/nhis/released200609.htm
Health Insurance Coverage: NHIS data in Health, U.S. From: http://www.cdc.gov/nchs/hus.htm
Using NCHS Data Tools to Find Data on Health Insurance To find data on health insurance, we will look at 3 tools: • Health Data for All Ages • SLAITS data from the CAMHI Data Resource Center • Data2010 (Healthy People 2010 Objectives) Please Note: You can also find health insurance data from Trends in Health and Aging, SETS, DataFerrett and ICPSR
In this pretabulated table, NHIS data years are combined to make the statistics more reliable and more useful for breakdowns by age, sex, race/ethnicity and geography.
The view is now the percentage (with upper and lower bound confidence intervals and standard error) of uninsured children (ages 0-17) by sex.

An online query system, with national and State data available
Creating a table with %, CI, n, and a weighted estimate (you can also compare one subgroup at a time)
DATA2010: • Another query system--very similar to WONDER and WISQARS • most recent data for Healthy People 2010 • 467 objectives • National and state data (if available)
All of the outputs contain a baseline, target and available data
Finding Data on C-Sections: Non-Tools Data are released from Natality Branch (Birth Certificate Data) • In ASCII (raw data files—you need your own statistical package to use, like SAS, SPSS, or STATA) • On the Internet, such as a FASTSTAT • In publications, such as Health, United States, etc.
Using NCHS Data Tools to Find Data on C-Sections To find data on c-sections, we will look at 3 tools: • the Office on Women’s Health (Quick Health Data Online) tool • the VitalStats site (this site is note live yet, but wanted to give you all a preview of it…) • the Statistical Export and Tabulation System (SETS)—the only tool not available online yet
An online query system. Find data by topics (11), some State data is available.
VitalStats: A Site Not Yet Available, but Coming Soon! Another site with tables, ready for custom-ization. This site also has data files and mapping. State and national data are available.
Using VitalStats data files and tables Here, I created a table from a data file. I used a c-section variable, a race recode and state of residence. Again, please note these data are not live…this is a DRAFT site!
Mapping on VitalStats Again, please note these data are not live…this is a DRAFT site!
Mapping on VitalStats (zoom) I changed the view to look at only “primary” c-sections and then panned an zoomed the view and highlighted the lovely state of Massachusetts.
Using SETS to Access C-Section Data When you use SETS, one of the database systems, you have full access to the complete data set. You can even also browse the data record by record or variable by variable.
Using SETS to create Primary C-Section Table for Suffolk County, MA
Using SETS to Create a Cesarean Delivery Table- Recodes You can recode the variables in the data set for your needs. For instance, if you wanted to look at a different age group than what’s provided on the data file, you could recode age groups. I combined two groups for two new categories of age: “Under age 20 years” and “40-49 years.”
Advantages: Pretabulated, don’t have to worry about misusing data—all concerns are addressed! Lots of data from many data sources, organized by topics Nice presentation capabilities (VitalStats will have mapping) Not as fast as online queries, but still fairly fast Disadvantages: May not contain the data needed Can only use options already in table (or data file, on VitalStats) A little learning curve Interactive Data Tables
Advantages: Fast, easy and online! Lots of data from many data sources, organized by topics Lots of data available Disadvantages: May not contain the data needed Can only use options available Generally descriptive Simple Queries
Advantages: Complete access to data set (in SETS—also documentation) More flexibility with the data Encourages greater understanding Good searching capabilities Access to other data sources Disadvantages: Some learning curve SETS and FERRETT require downloads and ICPSR requires log in May not have all the analytic capabilities for complete analysis (export) but better than the other tools May require more knowledge about the data Complex Queries
