Prevent Group B Strep App for Obstetric and Neonatal Providers

On June 25, 2019, the American College of Obstetricians and Gynecologists (ACOG) released updated guidance for prevention of early-onset group B Streptococcus (GBS) disease in newborns. On July 8, 2019, the American Academy of Pediatrics (AAP) released a new clinical report for management of infants at risk for GBS disease. This app does not yet reflect the changes incorporated into the new guidance. Please review ACOG’s 2019 Committee Opinionexternal icon and AAP’s Clinical Reportexternal icon to read what changes were made. Developers plan to update the app in the coming months and apologize for any inconvenience this delay may cause.
