Emergency department use after pediatric pharmaceutical ingestion: comparison of two national databases

Abstract

These results are close suggesting that the actual number is near these numbers. The NPDS number is greater than NEISS-AIP point estimate but within the 95% confidence interval. As NPDS is an actual count and NEISS-AIP is an extrapolation from a sample, to the extent that every child presenting to an ED following a medication exposure is not reported to a poison center, both databases may underestimate the problem. The NEISS-AIP extrapolation tool may need to be reassessed.
