Abstract

Abstract: There has been an increase in hepatitis B (HBV) detection during pregnancy in the United States and an emphasis on measures to decrease mother‐to‐child transmission of HBV. We performed a multicentre retrospective study (2015–2018) evaluating care among all women with HBV during pregnancy. We determined rates and predictors of adherence to key maternal care measures including: (1) referral to HBV specialty care, (2) assessment of HBV DNA, and (3) initiation of antiviral therapy, and (4) rates of HBIG and HBV vaccine completion in infants. We evaluated two interventions to improve HBV care: (1) clinical decision support with best practice alert and (2) co‐location of HBV care in obstetrics department. We identified 372 women with HBV during pregnancy. Patients had a median age of 33 (IQR 29, 36), were mostly of Asian (49%) or Black (36%) race, HBeAg‐negative (83%) with HBV DNA ≤2000 IU/mL (65%) and maximum ALT ≤25 (66%). Regarding care measures, 62% were referred to an HBV specialist, 85% had HBV DNA checked during pregnancy and 68% with HBV DNA ≥200, 000 were initiated on antiviral therapy. Co‐located obstetric‐liver diseases clinics appeared to improve adherence to maternal care measures. All infants received HBIG and the first HBV vaccine dose, 106 (81%) received the second, 94 (74%) received the 3rd dose, but fewer at the recommended time intervals. We identified clear gaps in adherence to HBV care measures for both mothers and infants. Co‐location of HBV care in the obstetrics department shows promise in improving adherence to maternal care measures.
