Referral to telephonic nurse management improves outcomes in women with gestational diabetes.

Objective: We sought to determine whether, among women with gestational diabetes mellitus, referral to a telephonic nurse management program was associated with lower risk of macrosomia and increased postpartum glucose testing.

Study Design: There was medical center-level variation in the percent of patients referred to a telephonic nurse management program at 12 Kaiser Permanente medical centers, allowing us to examine in a quasi-experimental design the associations between referral and outcomes.

Results: Compared with women from centers where the annual proportion of referral nurse management was <30%, women who delivered from centers with an annual referral proportion >70% were less likely to have a macrosomic infant and more likely to have postpartum glucose testing (multiple-adjusted odds ratio, 0.

The risk of large for gestational age across increasing categories of pregnancy glycemia.

Objective: We sought to estimate the risk of large for gestational age (LGA) across categories of glucose tolerance.

Study Design: In a cohort of 89,141 participants, women without gestational diabetes mellitus (GDM) were categorized by their screening and diagnostic test results; those with GDM were categorized as meeting the National Diabetes Data Group or only the American Diabetes Association (ADA) criteria. Multivariable logistic regression models estimated the risk of LGA; screening values 5.
