Voluntarily reported immunization information system (IIS) data can reliably estimate regional immunization coverage in children. This study found moderate agreement between IIS and telephone survey data, confirming IIS feasibility for public health planning.

Area of Science:

  • Public Health
  • Epidemiology
  • Health Informatics

Background:

  • Accurate immunization coverage data is crucial for public health planning.
  • Immunization Information Systems (IISs) may have compromised reliability due to low provider participation in non-mandated reporting states.
  • Telephone surveys are resource-intensive alternatives for collecting immunization data.

Purpose of the Study:

  • To test the reliability of voluntarily reported IIS data.
  • To assess the feasibility of using IIS data for estimating regional immunization rates.
  • To compare IIS data with traditional telephone survey data.

Main Methods:

  • Matched 553 telephone survey records (19-35 months old, 2013) with 430 San Diego County IIS records.
  • Assessed data concordance using Cohen's kappa (κ) for agreement.

  • Employed multivariable logistic regression to identify demographic differences and construct predictive weights.

    • Main Results:

    • Moderate agreement (κ = 0.35–0.49) was found for diphtheria, tetanus, acellular pertussis, pneumococcal conjugate, and Haemophilus influenzae type b vaccines.
    • Fair agreement (κ = 0.39) was observed for varicella and polio vaccines.
    • Slight agreement (κ = 0.17) was noted for the hepatitis B vaccine.

    Conclusions:

    • Factors predicting immunization coverage were consistent between telephone surveys and IIS data.
    • Voluntarily reported IIS data are feasible for assessing immunization rates in young children (19-35 months).
    • IIS data can support public health program planning, even with voluntary participation.
