MAT-LINK: MATernaL and Infant NetworK to Understand Outcomes Associated with Medication for Opioid Use Disorder during Pregnancy

MAT-LINK is a surveillance system to monitor maternal, infant, and child health outcomes associated with medication for opioid use disorder during pregnancy.

  • Opioid use during pregnancy increases the risk of neonatal abstinence syndrome (NAS). Recent evidence suggests that children born with NAS may be at increased risk for developmental delays.1,2
  • Opioid use during pregnancy has also been associated with other adverse health effects, including poor fetal growth, preterm birth, stillbirth, and specific birth defects.3
  • Health outcomes, including long-term outcomes, have not been systematically studied for children with prenatal opioid exposure.
  • Through funding from the Assistant Secretary for Planning and Evaluation’s Patient-Centered Outcomes Research Trust Fund, CDC’s National Center on Birth Defects and Developmental Disabilities established MAT-LINK.


  • Improve understanding of the range of maternal, infant, and child health outcomes through six years of age associated with medication for opioid use disorder during pregnancy.
  • Examine the possible effects of exposure to multiple substances and other risk factors on maternal and infant outcomes.

How These Data Are Collected and Used

  • Data on maternal, infant, and child health outcomes associated with medication for opioid use disorder during pregnancy are being collected across seven clinical sites: Boston Medical Center Corporation, Kaiser Foundation Research Institute (Center for Health Research-Northwest), The Ohio State University, University of New Mexico, University of Rochester, University of South Florida, and University of Utah.
  • Results from MAT-LINK will be used to inform clinical practice recommendations and clinical decision-making around medication for opioid use disorder among pregnant people.
  • In addition, this project will develop and pilot a data platform to collect and link maternal, infant, and child data across clinical sites. This can serve as a model for collecting data on other exposures during pregnancy.

Opportunities for the Future

An evaluation of MAT-LINK was done in 2021 to look at the system’s timeliness, flexibility, acceptability, data quality, and interoperability. This work will help improve the performance of the system in the years ahead.
