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 DatabaseSM 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.
