2.2.0.0 Preconception Care
Recommendations
14.4 Women with preexisting type 1 or type 2 diabetes who are planning pregnancy or who have become pregnant should be counseled on the risk of development and/or progression of diabetic retinopathy. Dilated eye examinations should occur ideally before pregnancy or in the first trimester, and then patients should be monitored every trimester and for 1-year postpartum as indicated by the degree of retinopathy and as recommended by the eye care provider. B
14.5 Women with preexisting diabetes should ideally be managed in a multidisciplinary clinic including an endocrinologist, maternal-fetal medicine specialist, dietitian, and diabetes educator, when available. B
Preconception visits should include rubella, syphilis, hepatitis B virus, and HIV testing, as well as Pap test, cervical cultures, blood typing, prescription of prenatal vitamins (with at least 400 mg of folic acid), and smoking cessation counseling if indicated. Diabetes-specific testing should include A1C, thyroid-stimulating hormone, creatinine, and urinary albumin-to-creatinine ratio; review of the medication list for potentially teratogenic drugs, i.e., ACE inhibitors (10), angiotensin receptor blockers (10), and statins (11,12); and referral for a comprehensive eye exam. Women with preexisting diabetic retinopathy will need close monitoring during pregnancy to ensure that retinopathy does not progress (13). Preconception counseling should include an explanation of the risks to mother and fetus related to pregnancy and the ways to reduce risk and include glycemic goal setting, lifestyle management, and medical nutrition therapy.
Several studies have shown improved diabetes and pregnancy outcomes when care has been delivered from preconception through pregnancy by a multidisciplinary group focused on improved glycemic control (14-16). One study showed that care of preexisting diabetes in clinics that included diabetes and obstetric specialists improved care (17). However, there is no consensus on the structure of multidisciplinary team care for diabetes and pregnancy, and there is a lack of evidence on the impact on outcomes of various methods of health care delivery (18).
