Hepatitis B Birth Dose Vaccination Improvement Initiative: The 24-Hour Baby Bundle.

Background: An estimated 25,000 infants are born to mothers diagnosed with hepatitis B virus (HBV) each year in the United States. Administration of the birth dose HBV vaccine prevents transmission during delivery. Despite national guidelines promoting vaccination within 24 hours of birth, fewer than 70% of infants receive the dose in their first 3 days of life. To improve compliance with national recommendations, Northwestern Medicine implemented a bundled care initiative in the well newborn nursery, entitled the 24-hour baby bundle (24-HBB).

Purpose: Evaluate the 24-HBB's effect on improving time to HBV vaccine administration.

Methods: The 24-HBB was created by an interdisciplinary team and implemented on February 17, 2020. Bundled care begins at 23 hours of life, starting with the HBV vaccine, followed by bath, weight, and congenital heart disease screening, and ending with metabolic screening. We conducted a retrospective cohort study of 22,057 infants born at Northwestern Medicine Prentice Women's Hospital in Chicago, Illinois. Our sample included preintervention birthdates between February 16, 2019, and January 16, 2020, and postintervention birthdates between March 17, 2020, and February 16, 2021, with a 2-month washout education period between January 17, 2020, and March 16, 2020.

Results: Hepatitis B virus immunization within 24 hours increased significantly from 43.83% to 66.90% (P < .0001). In addition, overall hepatitis B immunization prior to discharge significantly increased after implementation of the 24-HBB (98.18% vs 98.82%, P < .0001).

Implications for practice and research: The 24-HBB is effective at increasing rates of HBV immunization within 24 hours of birth. Newborn nurseries may benefit from similar initiatives to prevent hepatitis B infection, satisfy national recommendations, and promote childhood vaccination compliance.
