Impact of an Electronic Clinical Decision Support Tool on Early Maternal Glucose Screening in Pregnancy

Gestational diabetes mellitus (GDM), diabetes diagnosed in the second or third trimester of
pregnancy that is not clearly overt diabetes, has become more common as the rates of obesity in women of childbearing age have increased. Undiagnosed, uncontrolled diabetes in pregnancy can lead to maternal and infant health comorbidities as well as have adverse long-term effects for mother or baby. Although routine screening for gestational diabetes mellitus (GDM) occurs between 24 and 28 weeks gestation, the American Congress of Obstetricians and Gynecologists (ACOG) recommends screening earlier in pregnancy for women at risk for undiagnosed type 2 diabetes. Risk factors include previous history of GDM, known impaired glucose metabolism, or obesity (BMI > 30).

The purpose of this project is to implement the clinical practice guideline for early maternal glucose screening during pregnancy in women with risk factors through the integration of a clinical decision support (CDS) tool in an electronic health record (EHR). CDS tools can be utilized as a point of care strategy to remind providers of the clinical practice guidelines and to assist providers in decision-making related to screening. Participating providers (n=18) utilized the CDS tool during the initial obstetrical visit for at risk women without a pre-pregnancy diabetes diagnosis and entering prenatal care prior to 24 weeks. The impact of
implantation of the CDS tool shows that an increase in screening was statistically significant (p<.001).
