Early Postpartum Glucose Testing in Women with Gestational Diabetes Mellitus.

Objective Given that most women with gestational diabetes mellitus (GDM) never undergo the recommended 6 to 12 weeks postpartum glucose tolerance test (GTT), we assessed the feasibility of performing GTTs on postpartum day 2. Study Design Women with abnormal postpartum day 2 results were similar to women with normal postpartum day 2 results except that more women with abnormal results required medicine to treat their GDM (Table 1). [corrected]. We assessed the feasibility of this GTT and compared the results to the standard of care GTT at 6 to 12 weeks postpartum. We also evaluated maternal and pregnancy characteristics of women who return for 6 to 12 weeks GTTs compared with those lost to follow-up. Results In this study, 98 of 106 participants (92%) completed the postpartum day 2 GTT; 59% had normal glucose values at that time. Only 49 women returned at 6 to 12 weeks postpartum. Among women who had testing at both time points, the 2 days postpartum GTT were 100% sensitive and 94% specific for diabetes mellitus but less sensitive and specific for milder forms of abnormal glucose. Women who did not return for testing at 6 to 12 weeks postpartum were more likely to have less education, have Medicaid, and to have GDM previously (Table 2). [corrected]. Conclusion Performing GTTs on postpartum day 2 is feasible and should be further investigated as an alternative postpartum testing regimen in GDM.
