Abstract

BACKGROUND:

The accuracy of vaccine administration information recorded in administrative claims databases is uncertain.

METHODS:

We conducted a retrospective cohort study using the HealthCore Integrated Research Database(SM) among infants who received at least 1 RotaTeq (RV5) dose during the first year of life between February 1, 2006 and November 30, 2012 and were enrolled in the health plan at birth. We reviewed medical records for a sample of infants to validate vaccine administration information.

RESULTS:

We identified 169,560 infants who received at least 1 RV5 dose. Medical records were obtained for 85 infants, of which 74 (PPV1 87.1%; 95% CI 78.0-93.4%) had a corresponding first RV5 vaccination in the medical record with the same or similar administration date.

CONCLUSIONS:

Administrative claims contained inaccuracies in dose number or administration date for 13% of RV5 first doses identified.
