Strategies associated with higher postpartum glucose tolerance screening rates for gestational diabetes mellitus patients.

BACKGROUND Most women with histories of gestational diabetes mellitus do not receive a postpartum screening test for type 2 diabetes, even though they are at increased risk. The objective of this study was to identify factors associated with high rates of postpartum glucose screening. METHODS This cross-sectional analysis assessed characteristics associated with postpartum diabetes screening for patients with gestational diabetes mellitus (GDM)-affected pregnancies self-reported by randomly sampled licensed obstetricians/gynecologists (OBs/GYNs) in Ohio in 2010. RESULTS Responses were received from 306 OBs/GYNs (56.5% response rate), among whom 69.9% reported frequently (always/most of the time) screening women with GDM-affected pregnancies for abnormal glucose tolerance at the postpartum visit. Compared to infrequent screeners, OBs/GYNs who frequently screen for postpartum glucose tolerance were statistically (p<0.05) more likely to have a clinical protocol addressing postpartum testing (67.2% vs. 26.7%), an electronic reminder system for providers (10.8% vs. 2.2%) and provide reminders to patients (16.4% vs. 4.4%). Frequent screeners were more likely to use recommended fasting blood glucose or 2-hour oral glucose tolerance test (61.8% vs. 34.6%, p<0.001) than infrequent screeners. CONCLUSIONS Strategies associated with higher postpartum glucose screening for GDM patients included clinical protocols for postpartum testing, electronic medical records to alert providers of the need for testing, and reminders to patients.
