Determining Infant Age from Claims Data without a Birth Date

DLH research scientists Julia Ward, Casey Pierce, John Lim, and Lydia Feinstein were authors of a poster presented at the 2018 International Conference on Pharmacoepidemiology & Therapeutic Risk Management. The poster described a validation study that suggested that enrollment date likely provides a valid estimate of birth date among infants enrolled in private insurance during their birth year. As a result, age granularity can be retained when exact birth date is not present in administrative claims data. Poster coauthors were affiliated with the Gillings School of Global Public Health at the University of North Carolina and Johns Hopkins University School of Medicine.
