title: Postpartum diabetes screening in women with a history of gestational diabetes.
abstract: OBJECTIVE
  Women with a history of gestational diabetes mellitus (GDM) are at high risk for developing type 2 diabetes (diabetes mellitus, DM). The American Diabetes Association recommends regular postpartum diabetes screening for women with a history of GDM, but the American College of Obstetricians and Gynecologists (ACOG) is not as directive. We sought to examine postpartum glycemic testing in women diagnosed with GDM.
  
  
  METHODS
  We conducted an observational cohort study of women diagnosed with GDM at one of two large academic medical centers between 2000 and 2001. Kaplan-Meier estimates of the time from delivery to the first postpartum DM screening tests were determined, and predictors of postpartum DM screening were examined using Cox proportional hazards testing.
  
  
  RESULTS
  Only 37% of eligible women underwent the postpartum diabetes screening tests recommended by the American Diabetes Association (fasting glucose or oral glucose tolerance test [OGTT]), with a median time from delivery to the first such testing of 428 days. By comparison, 94% of women underwent postpartum cervical cancer screening using a Papanicolaou (Pap) test, with a median time from delivery to Pap testing of 49 days. Even when random glucose testing was included in a broad definition of postpartum DM screening (random or fasting glucose, glycosylated hemoglobin, or OGTT), only two thirds of women (67%) received a postpartum glycemic assessment.
  
  
  CONCLUSIONS
  In the population studied, only 37% of women with a history of GDM were screened for postpartum DM according to guidelines published by the American Diabetes Association. Efforts to improve postpartum DM screening in this high-risk group are warranted.
