The purpose of the Gestational Diabetes Group Program (GDGP) was to provide patients with diabetes self-management education that occurs in a supportive, prenatal group care setting. The Centering Pregnancy Interdisciplinary Model of Empowerment and the Chronic Care Model guided the program. The pilot project took place at an urban clinic that cares for a diverse, underserved population. The GDGP, a series of four prenatal group sessions after the diagnosis of gestational diabetes and one postpartum group, used an interprofessional/interdisciplinary approach to care with the groups cofacilitated by certified nurse-midwives, certified diabetes nurse-educators, and other community partners. The program was able to show statistically significant changes in knowledge and empowerment, optimal pregnancy outcomes, and high patient satisfaction.
