This Healthcare Cost and Utilization Project (HCUP) Statistical Brief presents statistics on treat-and-release ED visits (i.e., visits that result in discharge from the ED and do not result in admission to the same hospital) for pregnant women aged 12–55 years using weighted estimates from the 2019 Nationwide Emergency Department Sample (NEDS). The distribution of ED visits and aggregate ED costs by primary expected payer is presented overall as well as by patient age group and race and ethnicity. Corresponding statistics for ED visits for nonpregnant women aged 12–55 years are provided for comparison. Because of the large sample size of the NEDS data, small differences can be statistically significant. Thus, only differences greater than or equal to 10 percent are discussed in the text.
