To the Editor We read with great interest the novel way of analyzing the Healthcare Cost and Utilization Project (HCUP) data for neonatal abstinence syndrome (NAS) by Strahan et al.1 They also reported that they were unable to compare past published studies because they adopted the “in-hospital births” restriction in their study. Therefore, we used the 2012 Kids’ Inpatient Database provided by HCUP, Agency for Healthcare Research and Quality (AHRQ), and their partners to compare briefly the key findings of overall incidence, racial/ethnic differences, and primary insurance form using the same selection criteria and appropriate International Classification of Diseases, Ninth Revision (ICD-9) code (https://www.hcup-us.ahrq.gov/kidoverview.jsp).
