02 Nov EHRN: Risk of Pregnancy Complications Also a Concern for Younger Patients
We continued to evaluate additional complication rates by maternal age for gestational hypertension, preterm delivery, low birth weight, and postpartum hemorrhage. We found rates for this subset of complications were higher for pregnant patients 21 and younger or 35 and older. For older patients, the rates begin to increase in the early 30s. We did not differentiate between first and subsequent pregnancies and deliveries in this investigation.
While our findings show the greatest rate of complication after age 35, we also found that pregnant patients 21 or younger show increased rates of certain complications, such as preterm delivery.
These data come from Cosmos, a HIPAA-defined Limited Data Set of more than 120 million patients from 141 Epic organizations including 832 hospitals and 13,421 clinics, serving patients in all 50 states. This study was completed by two teams, each composed of a clinician and research scientists who worked independently. The two teams came to similar conclusions.
