Data Quality
Surveillance data are useful for program management and policy
development only if it is good quality data. Erroneous conclusions
about a health problem in a population may be drawn from poor quality
data. The CDC provides technical assistance to PedNSS and PNSS
contributors to ensure that good quality data are submitted to these
surveillance systems.
This How To section is specifically for contributors that submit data to
PedNSS and PNSS. The information presented in this How To section can be
used by contributors to
- identify potential data quality problems so that efforts can be made
to improve data quality at the contributor and local level and
- to help users understand the edit criteria that identified the data
quality error.
Data quality problems can be caused by
- data processing issues such as contributor computer information
system constraints,
- problems extracting the data from these systems into CDC transaction
files, and
- clinic reporting errors.
CDC generates two data quality reports to assist states in improving
the quality of data included in the annual surveillance reports. They
include the Periodic Summary of Record Volume and Data Quality and the
Annual Summary of Record Volume and Data Quality reports.
