[BDSP. Notice produite par INIST NZ7GCR0x. Diffusion soumise à autorisation]. Context In July 1999, due to concerns about thimerosal content, the American Academy of Pediatrics (AAP) and the Public Health Service (PHS) recommended suspending hepatitis B virus (HBV) vaccination at birth except for mothers who had positive or unknown hepatitis B surface antigen (HBsAg) status. In September 1999, the Centers for Disease Control and Prevention recommended that hospitals resume HBV vaccination at birth with a new thimerosal-free vaccine. Whether the 2 changes in recommendations within 3 months led to less-than-optimal compliance in hospital nurseries is unknown. Objective To determine hospital HBV vaccination policy before the recommendation for delay of HBV vaccination and 1 year later. Design, Setting, and Participants Survey of all 46 hospitals with obstetric services and neonatal nurseries in Cook County, Illinois. Main Outcome Measures Hepatitis B virus immunization practices before July 1999 and in August 2000 ; hospital factors associated with routine HBV immunization and compliance with AAP and PHS recommendations. Results Before July 1999,74% of surveyed hospital nurseries offered HBV vaccine to all neonates ; only 39% did so in August 2000. Being located in the Chicago city limits (88% vs 57% ; P=02) and having an academic affiliation (93% vs 66% ; P=05) were positively associated with routine neonatal immunization before July 1999.
