  1. Fulltext. Quality of HMO vaccination databases used to monitor childhood vaccine safety.

    Article - En anglais


    The availability of large, population-based, automated, medical care databases provides unique opportunities for monitoring the safety of childhood vaccines.

    The authors assessed the quality of automated vaccination databases by comparing them with vaccinations documented in paper-based medical records at three large US West Coast health maintenance organizations (HMOs) participating in the Vaccine Safety DataLink (VSD) study, a Centers for Disease Control and Prevention collaborative study of childhood vaccine safety.

    The authors randomly selected 1% or 2% samples of VSD study populations (n=1,224-2,577) for data quality analyses.

    Agreement between automated and abstracted vaccinations required identical triads of child identification number, vaccination date, and vaccine type.

    Separate analyses were conducted for each HMO and for each vaccine type administered between 1991 and 1995.

    Agreement was measured by three matching proportions : 1) the proportion of automated vaccinations present in the abstracted source, 2) the proportion of abstracted vaccinations present in the automated source, and 3) the proportion of vaccinations from either source present in both sources.

    Overall, for common childhood vaccines, proportion 1 ranged from 83% to 99%, proportion 2 ranged from 82% to 98%, and proportion 3 ranged from 70% to 97%. Lack of automated data was the most frequent type of discrepancy, followed by date mismatches and vaccine type mismatches. (...)
