Team-Based Approach to Managing Postpartum Screening of Women with Gestational Diabetes for Type 2 Diabetes

Approximately 6% of pregnant women develop gestational diabetes mellitus (GDM), which is a strong risk factor for developing type 2 diabetes mellitus. It is recommended that women with GDM complete a 75-g oral glucose tolerance test (OGTT) 4 to 12 weeks postpartum to screen for type 2 diabetes. A 3-month retrospective chart review in 2 patient-centered medical homes found that postpartum screening for type 2 diabetes was performed in only 39% of eligible women, despite recommendations from the American College of Obstetricians and Gynecologists (ACOG) and the American Diabetes Association. Thus, a quality improvement project was initiated to improve the postpartum type 2 diabetes screening rate.

This quality improvement project involved an education session that described current ACOG recommendations for diabetes screening. The education session included a pretest and posttest that evaluated participants' understanding about development of type 2 diabetes after GDM. A team-based postpartum guideline designed to enable women to complete a 75-g OGTT at the 4-to-12-week postpartum appointment was implemented. A postintervention chart review was conducted to determine the postintervention rate of type 2 diabetes screening.

The mean pretest score for the clinical team was 57%, and the mean posttest score was 99%. Postpartum screening for women with GDM was improved from 39% of women for whom screening was indicated to 77% with the implementation of the team-based guideline.

The quality improvement project results demonstrated that improved understanding of ACOG recommendations combined with the implementation of a team-based guideline significantly improved postpartum screening for type 2 diabetes. Team-based management of care, including education of team members about the rationale for change, may also improve outcomes in other quality improvement projects.
