From 2016–2022 in U.S. delivery hospitalizations, nontransfusion severe maternal morbidity rose from 72.0 to 93.0 per 10,000 deliveries, alongside increasing diabetes prevalence.
- Why it matters: Diabetes in pregnancy is common and linked to serious complications, but population-level trends and how different diabetes types relate to severe maternal morbidity are not well characterized across recent years.
- What they did: Using a retrospective analysis of 25,138,817 U.S. delivery hospitalizations (women ages 12–55) from the Healthcare Cost and Utilization Project National Inpatient Sample, the study estimated relative risks with modified Poisson regression for overall and nontransfusion SMM.
- The result: Compared with women without diabetes, nontransfusion SMM risk was highest for pregestational type 1 diabetes (RR 4.94; 95% CI 4.55–5.35), then type 2 (RR 2.58; 95% CI 2.43–2.74) and GDM (RR 1.12; 95% CI 1.08–1.15).
