Obstetricians seldom provide postpartum diabetes screening for women with gestational diabetes.

Objective: We aimed to determine whether obstetrician-gynecologists provided postpartum type 2 diabetes mellitus screening for women with a history of gestational diabetes.

Study Design: We identified women diagnosed with gestational diabetes, and then assessed whether obstetrician-gynecologists provided postpartum diabetes mellitus screening by ordering American Diabetes Association-recommended glucose tests or by referring women to primary care physicians for such testing.

Results: Of 2617 gravid women with a 1-hour glucose challenge test, 90 had gestational diabetes and postpartum follow-up.
