OBJECTIVE Prospective evaluation of pregnancy outcomes in women with pregestational diabetes over 6 years.

RESEARCH DESIGN AND METHODS The ATLANTIC Diabetes in Pregnancy group provides care for women with diabetes throughout pregnancy. In 2007, the group identified that women were poorly prepared for pregnancy and outcomes were suboptimal. A change in practice occurred, offering women specialist-led, hub-and-spoke evidence-based care. We now compare outcomes from 2005 to 2007 with those from 2008 to 2010.

RESULTS There was an increase in the numbers attending preconception care (28–52%, P = 0.01). Glycemic control before and throughout pregnancy improved. There was an overall increase in live births (74–92%, P < 0.001) and decrease in perinatal mortality rate (6.2–0.65%, P < 0.001). There was a decrease in large-for-gestational-age babies in mothers with type 1 diabetes mellitus (30–26%, P = 0.02). Elective caesarean section rates increased, while emergency section rates decreased.

CONCLUSIONS Changing the process of clinical care delivery can improve outcomes in women with pregestational diabetes.
