MEDNAX Study of Neonatal Abstinence Syndrome Published in New England Journal of Medicine

FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--Apr. 27, 2015-- MEDNAX, Inc. (NYSE: MD) announced that a study of the increase in admissions to the neonatal intensive care unit (NICU) related to neonatal abstinence syndrome (NAS) has been published online in the New England Journal of Medicine.

NAS is a drug withdrawal syndrome that most commonly occurs after in utero exposure to opioids. From 2000 to 2009, the incidence of NAS in the United States nearly tripled, according to an article published in the Journal of the American Medical Association in 2012, concurrent with growth in the use of opioids by pregnant women.

Despite these increases, no study had yet evaluated changes in NICU utilization or management of infants with the syndrome. The study published by the NEJM, titled “Increasing Incidence of the Neonatal Abstinence Syndrome in U.S. Neonatal ICUs,” directly addresses this topic, relying on data from MEDNAX’s Clinical Data Warehouse, and found that NAS is responsible for a substantial and growing portion of resources dedicated to critically ill neonates in NICUs nationwide.

“This study highlights one of the most critical issues in neonatal medicine today, namely the increasing exposure of the fetus to narcotic drugs,” said Alan Spitzer, M.D., Senior Vice President for Research, Education and Quality at MEDNAX. “The rapidly rising rate of NICU admissions for neonates who are withdrawing from narcotic exposure during pregnancy is alarming and, most importantly, is a preventable problem. The study also highlights the value of ‘Big Data’ from the MEDNAX Clinical Data Warehouse in defining emerging issues such as this one.”

Using multiple cross-sectional analyses, researchers affiliated with MEDNAX’s Clinical Research, Education and Quality efforts analyzed infants with NAS from 2004 to 2013 in 299 NICUs across the United States from a de-identified dataset. During the study period, the rate of NICU admissions for NAS increased nearly four-fold, from 7 to 27 per 1,000 admissions; the median length of stay increased from 13 to 19 days; and the total percentage of nationwide NICU days devoted to care of NAS infants increased from 0.6% to 4.0%, representing a 6.7-fold increase.

In addition to publishing this study, MEDNAX has been an active participant in awareness efforts related to the rising burden of NAS on the United States healthcare system. In March, Dr. Stefan Maxwell, Chair of the West Virginia Perinatal Partnership, testified before a House of Representatives Committee on the topic in conjunction with the introduction of the Protecting Our Infants Act, which directs the Department of Health and Human Services to make recommendations for diagnosis and treatment of NAS.

Dr. Spitzer added, “It is important to note that while the neonatologist is the clinician confronted with this problem, by the time the infant arrives in the NICU, his or her pathway is already in motion. Women who are contemplating pregnancy must be made aware of the risks of narcotics to their fetus, so that the problem can be avoided.”

The study was a collaborative effort between MEDNAX and Baylor Scott & White Health. Veeral N. Tolia, M.D., a MEDNAX physician and faculty at Baylor University Medical Center’s Division of Neonatology and Department of Pediatrics, is the principal author, and Dr. Spitzer is senior author.
