Objective Due to poor adherence for glucose testing at 6‐ to 12‐week postpartum among women with gestational diabetes, we sought to determine whether a 2‐hour glucose tolerance test (GTT) during postpartum hospitalization is predictive of 6‐ to 12‐week postpartum glucose testing. Study Design An institutional review board‐approved prospective cohort study was performed over 3 years. Patients underwent an inpatient fasting 75‐g, 2‐hour GTT on either postpartum days 2 through 4 and instructed to follow up in 6‐ to 12‐weeks for postpartum glucose testing. Sensitivity, specificity, positive predictive value (PPV), and negative predictive values (NPV) of the immediate GTT to predict abnormal 6‐ to 12‐week postpartum glucose testing were determined. Results Eighty women enrolled in the study completed the immediate GTT; of these, only 35 (44%) underwent 6‐ to 12‐week postpartum glucose testing. The sensitivity, specificity, PPV, and NPV of the immediate GTT were 100, 42.8, 30.4, and 100%, respectively. Conclusion More than 50% of our study patients did not undergo recommended postpartum glucose testing, coinciding with similar poor follow‐up reported in the literature. With a high NPV and high sensitivity, a negative immediate GTT may obviate the need for the 6‐ to 12‐week GTT, while a positive GTT may identify women who should follow up closely.
