State-level abortion bans have significantly altered medical care for women who have miscarriages. Researchers from Oregon Health & Science University analyzed insurance data from more than 123,000 patients who miscarried before 10 weeks between 2018 and 2024 and found that medical professionals were less likely to offer evidence-based treatment in states with abortion bans. In states with restrictions, bans were associated with a 2.8% increase in “expectant management,” an approach where doctors closely monitor patients without immediate intervention. Spontaneous abortion is the most common complication of early pregnancy in the United States. The findings were published in JAMA.
