Researchers Evaluate One-Step vs. Two-Step Gestational Diabetes Screenings

Many healthcare facilities recently switched from a two-step gestational diabetes screening to a one-step process. At one facility, in particular, gestational diabetes diagnoses increased by up to 41% after this change, but there were no identifiable benefits to newborns or mothers.

This study was completed at the Kaiser Permanent Washington Health Research Institute and found that despite the increase in diagnoses with a one-step test, adverse outcomes also increased. For example, insulin use nearly quadrupled from 1.2% to 4.4%, while labor induction increased from 25.2% to 28.6%. Increases were also noted in neonatal hypoglycemia and non-stress testing, although differences were not identified in risk for macrosomia or cesarean delivery.

These findings were published in Obstetrics and Gynecology on September 27, 2018.7
