A new study from Vanderbilt University Medical Center researchers finds that new mothers who receive opioids after uncomplicated vaginal births face an increased risk of serious opioid-related events regardless of the opioid dosage, a finding that could significantly impact care delivery.

Andrew Wiese, PhD, MPH, assistant professor of Health Policy in the Division of Pharmacoepidemiology, authored the paper published online April 15 in Women’s Health Issues, with Sarah Osmundson, MD, MPH, associate professor of Obstetrics and Gynecology, and other researchers in the departments of Biostatistics and Health Policy.

The study examined roughly 147,000 women enrolled in TennCare — Tennessee’s Medicaid program — between 2007 and 2014 who gave birth and had received one or fewer opioid prescriptions prior to delivery.
