In 1998, The Canadian Diabetes Association published guidelines that recommended women diagnosed with gestational diabetes mellitus (GDM,) should be screened postpartum for Type 2 diabetes using a glucose tolerance test. We determined the rate of screening for Type 2 diabetes at the Ottawa Hospital before and after the publication of this guideline and found that none of the women in either period had been screened following this recommendation. We believe a reminder letter outlining the recommended screening test sent to the patient and/or her family physician would increase screening for Type 2 diabetes in women with previous GDM.
