2021 Periodicity Schedule updates

February 16, 2021

Screening for hepatitis C virus infection at least once after age 18 was among changes to the 2021 Bright Futures/AAP Recommendations for Preventive Pediatric Health Care (Periodicity Schedule). The change aligns the Periodicity Schedule with recommendations of the U.S. Preventive Services Task Force and Centers for Disease Control and Prevention.

The Periodicity Schedule delineates the recommended screenings and assessments at each well-child visit from birth to age 21. It is developed by the AAP Committee on Practice and Ambulatory Medicine and the Bright Futures Periodicity Schedule Workgroup.

Other changes were made to the Periodicity Schedule footnotes. Footnote 11 was updated to reflect the recommendations and resources in the 2020 AAP clinical report Promoting Optimal Development: Identifying Infants and Young Children with Developmental Disorders Through Developmental Surveillance and Screening. Footnote 12 was updated to reflect the recommendations and resources related to screening for autism spectrum disorder in the 2020 clinical report Identification, Evaluation, and Management of Children With Autism Spectrum Disorder.
