Safety of Drugs Used in Hospitalized Infants

Examining the safety of more than 10 medications in hospitalized infants using a large database with information from electronic health records.

Summary

Only 25% of approved drugs marketed in the United States have sufficient pediatric data to support product labeling by the FDA for dosing, safety, or efficacy in children. As a result, the majority of drugs administered to children are used off-label. Clinical trials to evaluate the safety of these drugs are lacking across pediatric age groups, due, in part, to concerns about exposing pediatric patients to the risks of prospective drug studies.

Retrospective observational studies carry minimal risk for participants. The use of a large database usually provides samples sizes large enough to make inferences about the population in question. In this PTN study, we will use the Pediatrix Medical Group database—a database prospectively created from electronic health records of infants admitted to more than 300 neonatal intensive care units (NICUs) in the United States. It is one of the largest repositories of data in neonatal medicine; the database includes approximately 22% of NICU patients nationally and over 90,000 NICU admissions annually.

Using retrospective data analysis techniques, we will estimate the incidence of adverse events for hospitalized infants exposed to drugs of interest, including proton pump inhibitors, octreotide, and 8 additional therapeutics. These results will be compared against those from an FDA pediatric pilot study comprising a network of 6 hospitals seeking to better understand both indications for off-label use and incidences of adverse events. The comparison of frequency of adverse events from the Pediatrix database and the FDA pediatric pilot study will facilitate understanding of the most appropriate information system for studying drug use and adverse events in infants.
