Summaries for patients. Screening for gestational diabetes mellitus: U.S. Preventive Services Task Force recommendation statement.

DESCRIPTION Update of 2003 U.S. Preventive Services Task Force (USPSTF) recommendation about screening for gestational diabetes. METHODS The USPSTF weighed the evidence on maternal and neonatal benefits (reduction in preeclampsia, mortality, brachial plexus injury, clavicular fractures, admission to the neonatal intensive care unit for serious illnesses) and harms (physical and psychological harms) of screening for gestational diabetes identified for their 2003 recommendation and the accompanying systematic review of articles published since the 2003 review for screening after 24 weeks' gestation. Additional searches were performed for evidence published from 1966 to 1999 on screening before 24 weeks. RECOMMENDATION Current evidence is insufficient to assess the balance of benefits and harms of screening for gestational diabetes mellitus, either before or after 24 weeks' gestation. (I statement.).
