Severe maternal morbidity (SMM) refers to unintended, serious complications of labor and delivery that sharply raise a mother's risk of death. In the United States, the SMM rate during childbirth nearly doubled between 1999 and 2021, rising from 0.8% to 1.8%.

What they work on
- Test whether the 2010 ACA Dependent Coverage Provision, which expanded private insurance to people under 26, is associated with lower severe maternal morbidity during childbirth, using Healthcare Cost and Utilization Project data.
- Test whether the 2014 ACA Medicaid expansion for low-income adults is associated with lower severe maternal morbidity during childbirth, using difference-in-difference-in-differences analysis of national and state hospital data.
- Assess whether extending Medicaid from 60 days to one year postpartum under the 2020 Families First Coronavirus Response Act is associated with lower severe maternal morbidity after delivery.
More about the research
Continuous health insurance from before pregnancy to one year after birth has been suggested as a way to prevent these complications. However, up to 80% of pregnant individuals lack such coverage, and little evidence links insurance policy changes to lower SMM rates. The project addresses this gap by treating major insurance policy changes as natural experiments.
Why it matters
Severe complications of childbirth are rising in the United States and raise the risk of maternal death. By measuring whether expanded private insurance, Medicaid expansion and extended postpartum Medicaid lowered SMM rates, this work could give policymakers evidence on which coverage policies protect pregnant and postpartum people, especially young and low-income individuals.
