Hypertension at delivery hospitalization – United States, 2016–2017

In this study, hospital discharge data from the 2016–2017 Healthcare Cost and Utilization Project were analyzed to describe national and, where data were available, state-specific prevalences of chronic hypertension and pregnancy-associated hypertension at delivery hospitalization. In 2016–2017, the prevalence of chronic hypertension was 216 per 10,000 delivery hospitalizations nationwide, ranging from 125 to 400 per 10,000 delivery hospitalizations in individual states. The prevalence of pregnancy-associated hypertension was 1021 per 10,000 delivery hospitalizations nationwide, ranging from 693 to 1382 per 10,000 delivery hospitalizations in individual states. The burden of hypertensive disorders in pregnancy remains high and varies considerably by jurisdiction.
