Patients were assigned randomly to 4 groups: reminders sent to both physician and patient, to physician but not patient, or to patient but not physician or no reminders were sent. The primary outcome was the proportion of patients who underwent an OGTT within 1 year after delivery. The secondary outcome was the performance of other postpartum screening tests.
OGTT rates were significantly increased in the physician/patient reminder group (49/81 women; 60.5 % ), in the patient-only reminder group (42/76 women; 55.3 % ), and in the physician-only reminder group (16/31 women; 51.6 % ) compared with the no reminder group (5/35 women; 14.3 % ; P < .05).
Postpartum reminders greatly increased screening rates for women with gestational diabetes mellitus.
