FIGURE 2.

This figure is a bar chart showing the proportion of deaths occurring during delivery hospitalization with a documented diagnosis code of a hypertensive disorder in pregnancy in the United States during 2017–2019— according to the National Inpatient Sample.

Proportion of deaths* occurring during delivery hospitalization with a documented diagnosis code of a hypertensive disorder in pregnancy†— National Inpatient Sample, United States, 2017–2019

Abbreviation: HDP = hypertensive disorder in pregnancy.

* This study did not assign cause of death but instead examined the proportion of in-hospital deaths with an HDP diagnosis code documented among delivery hospitalizations.

† HDPs are defined as chronic hypertension, pregnancy-associated hypertension (i.e., gestational hypertension, preeclampsia, eclampsia, and chronic hypertension with superimposed preeclampsia), and unspecified maternal hypertension. Proportions for chronic and unspecified maternal hypertension are combined to conform to the Agency for Healthcare Research and Quality’s data use agreement, which prohibits reporting estimates based on fewer than 11 unweighted observations.
