For
changes in the questionnaires: See Chapter 3 on ‘Content of NIS
Questionnaires’ in the Data User’s Guide (1995-2001).
For
changes in the data editing procedures: See Chapter 4, section on ‘Limitations
of Data Editing Procedures’ in the Data User’s Guide (1995-2001); some
provider-data editing procedures were not implemented in 1995-2001 NIS.
Changes
in the estimation procedure: For 1998, a new estimation procedure was
implemented to obtain vaccination coverage rates from the provider data.
For consistency, this procedure was applied to the NIS data for the years
1995-1997, and the resulting estimates are published on the
NIS Web site.
Published estimates of vaccination coverage
based on NIS data for years prior to 1998 (e.g., estimates published in
MMWR articles) may differ slightly from the estimates published on the NIS
Web site for the same NIS data. All Public-Use Data Files include the
sampling weight (W0) for the new estimation procedure. See Chapter 6,
section on ‘Adjustment for Provider Nonresponse’ in the Data User’s
Guide (1995-2001).
