The cost of medical care for preeclampsia is estimated to be $2.18 billion for the first year surrounding delivery, split almost evenly between care for mothers and infants, according to a new report.
Preeclampsia is increasing at a more rapid rate than diabetes, ischemic heart failure, Alzheimer’s disease, obesity, and chronic kidney disease – disorders for which substantially more funding has been allocated for research and treatment, said Warren Stevens, PhD, of Precision Health Economics, Los Angeles, and his associates.

To quantify the health care costs associated with preeclampsia, the investigators performed secondary analyses of several datasets and extrapolated from approximately 2 million births (1,918,498 without preeclampsia and 69,193 with preeclampsia) to derive nationally representative estimates. They focused on 18 major maternal and 13 major infant sequelae of preeclampsia, including maternal hemorrhage, thrombocytopenia, stroke, pulmonary edema, neurologic impairment, and renal injury, as well as infant respiratory distress, sepsis, intraventricular hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, and retinopathy.Compared with a healthy pregnancy, preeclampsia increased the probability that a mother would have at least one adverse outcome from 4.6% to 10.1%, and it increased the probability that an infant would have at least one adverse outcome from 7.9% to 14.2%. For mothers, preeclampsia was estimated to raise costs by $6,583 per birth, which translates to an increase of $1.03 billion for U.S. mothers during a single year (2012). For infants, the disorder raised costs by $1.15 billion during that year.
Infant costs varied according to the gestational age at delivery, ranging from $1,311 per birth at 36 weeks’ gestation to $150,000 per birth at 26 weeks’ gestation, Dr. Stevens and his associates reported (Am J Obstet Gynecol. 2017 Jul 11. doi: 10.1016/j.ajog.2017.04.032).
This study could not take into account longer-term adverse outcomes associated with preeclampsia. Women with a history of the disorder are at double the risk of developing ischemic heart disease or cerebrovascular disease compared with women without such a history, and at three times the risk of developing hypertension. Infants are at increased risk of developing stroke, metabolic syndrome, and chronic heart disease, the investigators noted.
