Mother-Infant Dyad program in primary care: evidence-based postpartum care following gestational diabetes

Gestational diabetes mellitus (GDM), a common complication of pregnancy, is associated with a 10-fold increased risk of type 2 diabetes mellitus (T2DM) compared to the general population. Evidence-based guidelines recommend that patients with GDM receive postpartum care for T2DM risk reduction including an oral glucose tolerance test (OGTT) 4-12 weeks after delivery, yet half of patients with GDM did not return for their postpartum visits by 12 weeks postpartum. Additionally, only 10% utilize primary care within 12 months of delivery and one-third of GDM patients receive timely postpartum OGTT.

To determine if the Mother-Infant Dyad postpartum primary care program provides a framework to link well-child visits with postpartum primary care visits to increase postpartum clinical interactions promoting longitudinal care, such as postpartum visit attendance and T2DM screening.

All patients with a diagnosis of GDM that received care at a postpartum mother-infant dyad program at a Midwestern academic medical center internal medicine and pediatrics primary care clinic were enrolled. Clinic level data was obtained by baseline and 6-month post-enrollment surveys and chart review. A comparison population was identified from Medicaid claims data using propensity score matching to enable a comparison of program participants' outcomes to a population comprised of similar individuals diagnosed with GDM that received care at sites not participating in the Dyad program. Our primary outcome was completion of T2DM screening in the 4-12 week postpartum period. The secondary outcomes were postpartum visit attendance with a prenatal provider, and prediabetes diagnoses.

A total of 75 mother-infant dyads were seen by the clinic. Of the enrolled women, 43% were Non-Hispanic White and 30% were Non-Hispanic Black; mean age was 30.75 years. The matched comparison group (n = 62) had a mean age of 30.75 years, were 43% Non-Hispanic White and 30% Non-Hispanic Black. Women who participated in the program were more likely to receive T2DM screenings than women who did not participate (87 vs. 79%, p<.001) and complete postpartum visits (95 vs. 58%, respectively; p<.001). Additionally, a higher rate of new prediabetes diagnoses was observed (12 vs. 6%, p < .001).

The Mother-Infant Dyad postpartum primary care program improved T2DM screenings and postpartum visit attendance. In addition, a greater proportion of Dyad program participants experienced new prediabetes diagnoses that those in the comparison group. Our findings suggest that the dyad care model, in which women with GDM engage in postpartum primary care concurrent with well-child visits, can improve longitudinal postpartum care after a GDM diagnosis.
