Area of Science:

  • Public Health
  • Biostatistics
  • Health Informatics

Background:

  • The National Center for Health Statistics (NCHS) prioritizes data quality since 1960.
  • Comparing statistics across data systems is crucial for monitoring data quality.

Purpose of the Study:

  • To focus on between-data-systems comparisons for evaluating data quality.
  • To describe methodological analyses for assessing statistical consistency and comparability.

Main Methods:

  • Evaluation of time trends in statistical data.
  • Estimation of survey method effects on data.
  • Assessment of response error and its impact.
  • Measurement of definitional and conceptual effects.
  • Detection of inconsistencies between different data systems.

Main Results:

  • Methodological analyses provide tools to evaluate data quality across systems.
  • Comparisons help ensure consistency and comparability of NCHS statistics.
  • Identified potential sources of error and inconsistency in statistical data.

Conclusions:

  • Between-data-systems comparisons are complex but essential for robust statistical agencies.
  • These comparisons offer net benefits for maintaining high-quality health statistics.
  • The described methods aid in comprehensive data quality monitoring.
