• Decade of NHIS technology change
• NHIS Re-engineering Project
• Impact of NHIS Re-engineering on user
• 2004 NHIS Draft Release Plan
• 2004 NHIS technology plans for NHIS
Decade of NHIS Technology Change
• 1997 Redesign
Questionnaire redesign – content & structure
Conversion from paper questionnaire to CAPI (computer assisted personal interview)
New post production systems
New data dissemination products – Internet and CD-ROM
Decade of NHIS Technology Change
• Consequences of adopting new technology for 1st time Timeliness issues – 2 year backlog of
production work
Efficiency issues – manual, redundant systems
Quality Issues – extensive clean-up/reformatting of data
• Ernst & Young - Evaluation of NHIS Redesign - 2000
NHIS Re-engineering Project
• Partnership with Census Bureau
• Components of Re-engineering CAPI Software conversion – DOS to
Windows• University of Michigan partnered on screen
design issues
Databases for specifications and analysis
New post production systems
NHIS Re-engineering Project
• Schedule 2001 – Work began 2003 – Pretest 2004 – January: data collection began 2005 – July release expected
• 1999-2003 NHIS production concurrent with Re-engineering
Impact of NHIS Re-engineering on the User
• Improve timeliness of micro data release: 6 months after data collection ends for most files
• Better documentation
• Reduce editing and recodes
• Reduce redundancy between files
2004 NHIS Draft Release Plan
• July 2005 – partial release
• October 2005 – complete release
Health Insurance – coded component
Maybe other files ???
Internet only
Future Technology Plans for NHIS
• Continuous Improvement Re-engineering provides foundation we will build
upon
• Analytic tools for the user SQL Server relational database technology
Data warehouses and data marts for specific analytic needs
• Historical NHIS Files on the Internet – prior to 1997
Provide feedback on National Health Interview Survey data product to the NHIS Listserve
