Hepatitis B screening and vaccination for all pregnant women?
Is universal hepatitis B screening and vaccination for pregnant women an upcoming change in prenatal care? In a related editorial, Martina L. Badell, MD, of the division of maternal-fetal medicine and department of gynecology and obstetrics at Emory University School of Medicine in Atlanta, emphasized the hepatitis B vaccine’s safety and effectiveness during pregnancy based on prior studies and compared a universal hepatitis B screening and vaccination program for pregnant women to how clinicians screen universally for rubella as standard of care in this group.
“Owing to the success of rubella vaccination campaigns, today there are fewer than 10 cases of rubella in the United States annually, and, since 2012, all of these cases have been in persons infected when living in or traveling to other countries,” she wrote. “Approximately 850,000 people are living with hepatitis B infection in the United States, and approximately 21,900 acute hepatitis B infections occurred in 2015. Despite the very different prevalence in these infections, we currently screen pregnant and nonpregnant patients for rubella immunity but not hepatitis B.”
If real-world studies bear out that a hepatitis B universal screening and vaccination program is cost effective, guidelines on who should be screened and vaccinated might need to be reconsidered, Dr. Prabhu said. Although following women for decades to see whether hepatitis B screening and vaccination is cost effective is impractical, “a lot of medicine has been predicated on risk-based strategies and risk stratifying, and there is a lot of value to approaching patients like that,” she explained.
How an ob.gyn. determines whether a patient is high risk and qualifies for hepatitis B vaccination under current guidelines is made more complicated by the large amount of information covered in a prenatal visit. There is a “laundry list” of risk factors to consider, and “patients are just meeting you for the first time, and so they may not feel comfortable completely sharing what their risk factors may or may not be,” Dr. Prabhu said. In addition, they may not know the risk factors of their partners.
Under guidelines where all pregnant women are screened and vaccinated for hepatitis B regardless of risk, “it doesn’t harm a woman to check one extra blood test when she’s already having this bevy of blood tests at the first prenatal visit,” she said.
Clinicians may be more aware of the need to add hepatitis B screening to prenatal care given that routine hepatitis C screening for pregnant women was recently released by ACOG as a practice advisory. “I think hepatitis is a little bit more on the forefront of the obstetrician or prenatal care provider’s mind as a result of that recent shift,” she said.
“A lot of women only really access care and access consistent care during their pregnancy, either due to insurance reasons or work reasons. People do things for their developing fetus that they might not do for themselves,” Dr. Prabhu said. “It’s a unique opportunity to have the time to build a relationship, build some trust in the health care system and also educate women about their health and what they can do to keep themselves in good health.
“It’s more than just about the next 9 months and keeping you and your baby safe, so I think there’s a real opportunity for us to think about the public health and the long-term health of a woman.”
