In 2019, CPQCC launched a maternal substance exposure database to improve understanding of care for infants with neonatal abstinence syndrome (NAS). By collecting data on all maternal substance exposures (including but not limited to opioids), we aim to improve healthcare for infants exposed in-utero and expand our knowledge on treatment and outcomes across the state. This webinar provides details of how to begin using MatEx data to learn about the infants in your unit and see how they compare to all MatEx participants. MatEx participant, UC Irvine, shares how they use the database and why they feel it is such a critical aspect of care.
