This regional prepregnancy care program is clinically effective. The cost of program delivery is less than the excess cost of managing adverse pregnancy outcomes.

The aim of this observational study was to evaluate screening and progression of diabetic retinopathy during pregnancy in women with pregestational diabetes attending five antenatal centres along the Irish Atlantic seaboard. An adequate frequency of screening was defined as at least two retinal evaluations in separate trimesters. Progression was defined as at least one stage of deterioration of diabetic retinopathy and/or development of diabetic macular edema on at least one eye. Women with pregestational diabetes who delivered after 22 gestational weeks (n = 307) were included. In total, 185 (60.3%) had an adequate number of retinal examinations. Attendance at prepregnancy care was associated with receiving adequate screening (odds ratio 6.23; CI 3.39–11.46 (P < 0.001)). Among those who received adequate evaluations (n = 185), 48 (25.9%) had retinopathy progression. Increasing booking systolic blood pressure (OR 1.03, CI 1.01–1.06, P = 0.02) and greater drop in HbA1c between first and third trimesters of pregnancy (OR 2.05, CI 1.09–3.87, P = 0.03) significantly increased the odds of progression. A significant proportion of women continue to demonstrate retinopathy progression during pregnancy. This study highlights the role of prepregnancy care and the importance of close monitoring during pregnancy and identifies those patients at the highest risk for retinopathy progression.

BackgroundPregnancy in women with type 1 (T1DM) or type 2 diabetes (T2DM) is associated with increased risk. These conditions are managed similarly during pregnancy, and compared directly in analyses, however they affect women of different age, body mass index and ethnicity.MethodsWe assess if differences exist in pregnancy outcomes between T1DM and T2DM by comparing them directly and with matched controls. We also analyze the effect of glycemic control on pregnancy outcomes and analyze predictive variables for poor outcome.ResultsWe include 323 women with diabetes and 660 glucose-tolerant controls. T2DM women had higher BMI, age and parity with a shorter duration of diabetes and better glycemic control. Preeclampsia occurred more in women with T1DM only. Rates of elective cesarean section were similar between groups but greater than in controls, emergency cesarean section was increased in women with type 1 diabetes. Maternal morbidity in T1DM was double that of matched controls but T2DM was similar to controls. Babies of mothers with diabetes were more likely to be delivered prematurely. Neonatal hypoglycemia occurred more in T1DM than T2DM and contributed to a higher rate of admission to neonatal intensive care for both groups. Adverse neonatal outcomes including stillbirths and congenital abnormalities were seen in both groups but were more common in T1DM pregnancies. HbA1C values at which these poor outcomes occurred differed between T1 and T2DM.ConclusionsPregnancy outcomes in T1DM and T2DM are different and occur at different levels of glycemia. This should be considered when planning and managing pregnancy and when counseling women.

OBJECTIVEProspective evaluation of pregnancy outcomes in pregestational diabetes along the Atlantic seaboard 2006–2007.RESEARCH DESIGN AND METHODSThe Atlantic Diabetes in Pregnancy group, representing five antenatal centers in a wide geographical location, was established in 2005. All women with diabetes for >6 months before the index pregnancy were included. Results were collected electronically via the DIAMOND Diabetes Information System. Pregnancy outcome was compared with background rates.RESULTSThere were 104 singleton pregnancies. The stillbirth rate (25/1,000) was 5 times, perinatal mortality rate (25/1,000) 3.5 times, and congenital malformation rate (24/1,000) 2 times that of the background population. A total of 28% of women received prepregnancy care, 43% received prepregnancy folic acid, and 51% achieved an A1C ≤7% at first antenatal visit.CONCLUSIONSWomen are not well prepared for pregnancy, and outcomes are suboptimal. A regional prepregnancy care program and centralized glucose management are urgently needed.
