Multidisciplinary Group Education for Gestational Diabetes Mellitus: A Prospective Observational Cohort Study.

The value of diabetes education, focusing on lifestyle measures, in women with gestational diabetes mellitus (GDM) is acknowledged, but requires intensive education and input of resources if done on an individual basis. Group education could be a valuable alternative to individual education. This study aims to investigate the impact of multidisciplinary group education on women's knowledge about GDM, education, treatment satisfaction, and emotional status. Two hundred women with GDM were enrolled in a prospective observational study. Dutch speaking women were offered group education at their first visit after GDM diagnosis. Non-Dutch speaking women or women for whom group education was not possible received individual education. Individual follow-up with a dietitian was planned within two weeks for all women. Women receiving individual education (n = 100) were more often from an ethnic minority background compared to women in group education (n = 100) (32.0% (n = 31) vs. 15.3% (n = 15), p = 0.01). Knowledge about GDM significantly improved after education, with few differences between the two education settings. Both patients in group and individual education were equally satisfied with the content and duration of the initial and follow-up education. Of all group participants, 91.8% (n = 90) were satisfied with group size (on average three participants) and 76.5% (n = 75) found that group education fulfilled their expectations. In conclusion, women diagnosed with GDM were overall satisfied with the education session's content leading to a better understanding of their condition, independent of the education setting. Group education is a valuable alternative to better manage the increasing workload and is perceived as an added value by GDM patients.

The 2019 Flemish consensus on screening for overt diabetes in early pregnancy and screening for gestational diabetes mellitus.

Screening for gestational diabetes mellitus (GDM) is important to improve pregnancy outcomes and to prevent type 2 diabetes after pregnancy. The 'International Association of Diabetes and Pregnancy Study Groups' (IADPSG) recommends a universal one-step approach with the 75 g oral glucose tolerance test (OGTT) for screening of GDM. The IADPSG recommendation remains controversial due to the important increase in GDM prevalence and increased workload. After review of the latest evidence and based on data from the 'Belgian Diabetes in Pregnancy' study, members of the Diabetes Liga, the Flemish associations of general physicians (Domus Medica), obstetricians (VVOG), midwives (VVOB), diabetes nurse educators (BVVDV) and clinical chemists (RBSLM) have reached a new consensus on screening for GDM in Flanders. This new consensus recommends universal screening for overt diabetes when planning pregnancy or at the latest at first prenatal contact, preferably by measuring the fasting plasma glucose by using the same diagnostic criteria as in the non-pregnant state. In women with impaired fasting glycaemia, but also in normoglycemic obese women and women with a previous history of GDM, lifestyle counselling is advised with screening for GDM with a 75 g OGTT at 24 weeks. In all other women, we recommend a two-step screening strategy with a 50 g glucose challenge test (GCT) at 24 weeks followed by a 75 g OGTT when the glucose level 1 hour after the GCT ≥130 mg/dl. Diagnosis of GDM is made using the IADPSG criteria for GDM. Postpartum screening for subsequent glucose abnormalities should be advocated and organized for every woman with GDM.

Glucose intolerance after a recent history of gestational diabetes.

Aim. Our aim was to evaluate the uptake of our current screening strategy postpartum and the risk factors for glucose intolerance in women with a recent history of gestational diabetes (GDM). Methods. Retrospective analysis of files of women with a recent history of GDM diagnosed with the Carpenter and Coustan criteria from 01-01-2010 till 31-12-2013. Multivariable logistic regression was used to adjust for confounders. Results. Of all 231 women with a recent history of GDM, 21.4% (46) did not attend the scheduled postpartum OGTT. Of the women tested, 39.1% (66) had glucose intolerance and 5.3% (9) had diabetes. These women were more often overweight (39.7% versus 25.3%, P = 0.009), were more often treated with basal-bolus insulin injections (52.0% versus 17.4%, P = 0.032), and had a lower beta-cell function and lower insulin sensitivity, remaining significant after adjustment for age, BMI, and ethnicity (insulin secretion sensitivity index-2 (ISSI-2) in pregnancy 1.5 ± 0.5 versus 1.7 ± 0.4, P = 0.029; ISSI-2 postpartum 1.5 (1.2-1.9) versus 2.2 (1.8-2.6), P = 0.020; Matsuda index postpartum 3.8 (2.6-6.2) versus 6.0 (4.3-8.8), P = 0.021). Conclusion. Glucose intolerance is frequent in early postpartum and these women have a lower beta-cell function and lower insulin sensitivity. One fifth of women did not attend the scheduled OGTT postpartum.
