Parental reports of timing of MMR receipt 6 months or more prior to biopsy were in accord with pediatric provider immunization charts for the final study population with the exception of one control boy whose immunization record revealed receipt of a second MMR 3.5 months prior to biopsy.

Specifically, the study objectives were firstly to assess levels of agreement between automated immunization registries and medical chart abstractions of vaccine refusals.
The study collected refusal information found in the medical record and in the HMO immunization registry of our chart review sample.
The immunization registry, compared to chart review, had negative predictive values of 85 92% and 90 97% for 2- and 6-year olds, and positive predictive values of only 52 74% and 59 62% to identify vaccine refusals.
Our results indicate that there is poor agreement between refusal status in charts and immunization registries.
