Overview of NCHS Data Access Tool Ease Level Available DATAFERRETT 15 Datasets, including NAMCS, NHANES, Mortality (UCOD), NHIS ICSPR Many datasets, including most NCHS surveys (Vital Stats available in ASCII only) SETS Selected NCHS sets: Over 80 Available!

Using Health Insurance Data: Non-Tools Data are released from NHIS and others Ø In ASCII (raw data files—you need your own statistical package to use, like SAS, SPSS, or STATA) Ø On the Internet, as an Early Release Ø 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/relea sed 200609. 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: üHealth Data for All Ages üSLAITS data from the CAMHI Data Resource Center üData 2010 (Healthy People 2010 Objectives) Please Note: You can also find health insurance data from Trends in Health and Aging, SETS, Data. Ferrett and ICPSR

HDAA has health insurance tables (pretabulated data)

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.

Charting and Exporting the Customized Data

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)

Creating a chart (with presentation selections)

DATA 2010: üAnother query system--very similar to WONDER and WISQARS ümost recent data for Healthy People 2010 ü 467 objectives üNational 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) Ø In ASCII (raw data files—you need your own statistical package to use, like SAS, SPSS, or STATA) Ø On the Internet, such as a FASTSTAT Ø 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: üthe Office on Women’s Health (Quick Health Data Online) tool üthe Vital. Stats site (this site is note live yet, but wanted to give you all a preview of it…) üthe 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.

Vital. Stats: A Site Not Yet Available, but Coming Soon! Another site with tables, ready for customization. This site also has data files and mapping. State and national data are available.

Using Vital. Stats 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 Vital. Stats Again, please note these data are not live…this is a DRAFT site!

Mapping on Vital. Stats (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 When you C-Section Data 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 Access C-Section Data

Using SETS to search for Suffolk County

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. ”

You can also chart and export your data

Data. Ferrett: A Tool from the Census Bureau

Interactive Data Tables Advantages: ü Pretabulated, don’t have to worry about misusing data—all concerns are addressed! ü Lots of data from many data sources, organized by topics ü Nice presentation capabilities (Vital. Stats will have mapping) ü Not as fast as online queries, but still fairly fast Disadvantages: ü May not contain the data needed ü Can only use options already in table (or data file, on Vital. Stats) ü A little learning curve

Simple Queries Advantages: ü Fast, easy and online! ü Lots of data from many data sources, organized by topics ü Lots of data available Disadvantages: ü May not contain the data needed ü Can only use options available ü Generally descriptive

Complex Queries Disadvantages: Advantages: ü Complete access to data ü Some learning curve ü SETS and FERRETT set (in SETS—also require downloads and documentation) ü More flexibility with the ICPSR requires log in ü May not have all the data analytic capabilities for ü Encourages greater complete analysis understanding (export) but better than ü Good searching the other tools capabilities ü May require more ü Access to other data knowledge about the sources data
