Expanding Medicaid coverage has proved beneficial to postpartum women and may even help reduce disparities, say two new papers.
In the first study, expansion of Medicaid coverage under the Affordable Care Act was associated with higher rates of postpartum coverage and outpatient visits, according to results published in JAMA Health Forum.
Racial and ethnic disparities were also reduced in postpartum coverage, although these disparities remained between Black and White women for outpatient visits.
In the second study, published in JAMA Network Open, researchers found that when postpartum care is covered as part of Emergency Medicaid, women who have been denied access because of their citizenship status are able to use these services, which includes contraception.
Federal law currently prohibits undocumented and documented immigrants who have been in the United States for less than 5 years from receiving full-benefit Medicaid. Coverage is limited to Emergency Medicaid, which offers benefits only for life-threatening conditions, including hospital admission for childbirth. Coverage is not available for prenatal or postpartum care, including contraception.
For the first article, lead author Maria W. Steenland, SD, of Brown University, Providence, R.I., and colleagues point out that compared with other high-income countries, maternal mortality is higher in the United States and largely driven by persistent racial disparities. Compared with non-Hispanic White women, the rates of maternal death are more than twice as high among American Indian and Alaska Native women, and more than threefold greater in non-Hispanic Black women.
“To be clear, visits increased by around the same amount for Black and White individuals after Medicaid expansion, it is just that visits started off lower among Black women, and remained lower by a similar degree,” said Dr. Steenland.
One explanation is that Black women experience racial discrimination during pregnancy-related health care including childbirth hospitalizations and this may make them more reticent to seek postpartum care, she explained. “In addition, the ability to seek health care is determined by insurance as well as other social factors such as paid leave from work, childcare, and transportation, and these other factors may have remained a larger barrier for Black women after expansion.”
In this cohort study, they looked at the association of Medicaid expansion in Arkansas with continuous postpartum coverage, postpartum health care use, and change in racial disparities in the study outcomes. Using the Arkansas All-Payer Claims Database for persons with a childbirth between 2013 and 2015, the authors identified 60,990 childbirths. Of this group, 67% were White, 22% Black, and 7% Hispanic, and 72.3% were covered by Medicaid. The remaining 27.7% were paid for by a commercial payer.
Before Medicaid expansion, 50.6% of women with Medicaid had continuous coverage during the 6 months postpartum, and the share of women with Medicaid childbirth coverage who were continuously covered for 6 months postpartum increased to 69.3% in 2014 and 90.0% in 2015. Medicaid expansion was associated with a 27.8% increase in continuous coverage for 6-12 months postpartum, and 0.9 increase in visits or a relative increase of 75.0% in outpatient care compared with the visit rate of 1.2 visits within the first 6 months postpartum during the pre-expansion period.
A subgroup analysis was conducted to see if Medicaid expansion had any effect on the disparities between White and Black patients. In the 2-year period after expansion, the percentage of both Black and White women with continuous 6-month postpartum coverage increased to 87.9% and 85.9%, respectively. White individuals averaged 2 visits in the first 6 months postpartum versus 1.6 for Black individuals before expansion, and even though there was no difference in postpartum insurance coverage after expansion, racial disparities in the number of visits during the first 6 months postpartum remained after Medicaid expansion (2.5 vs. 2).
Commenting on the paper, Catherine Cansino, MD, MPH, associate clinical professor in the department of obstetrics and gynecology at the University of California, Davis, noted that she has seen the benefits of Medicaid expansion among obstetric population in California. “I’m glad to see similar expansion in other states,” she said. “But to address persistent health care inequities, I think concierge services or patient care navigation serve a role and can hopefully put a little dent in narrowing gaps.”
Dr. Cansino noted that there are many postpartum patients who need help arranging both pediatric and postpartum care, often prioritizing the newborn appointments. “They also need childcare help so they can focus on their own care as well as transportation,” she said, adding that “it would also be interesting to review racial/ethnic differences with regard to knowledge about contraceptive need immediately postpartum and also about the stigma related to postpartum mental health disorders. If patients don’t see the value of a postpartum visit, they would tend not to attend this visit especially given the many other challenges in the postpartum period.”
