GDM, RECRUITMENT
This study demonstrates a significant increase in participation in screening among women with prior GDM who receive an email reminder in comparison with women who receive only standard care. Our results thereby corroborate the growing body of evidence that reminding women to be screened after birth are effective [Contextual factors may explain the variations in effect found between this study and previous studies [Our study also found a stronger effect of the reminder among urban women. However, it is important to notice that women from rural areas in general seems to participate in screening more than women from urban areas but might not be especially responsive to a reminder.The reminder nevertheless seems to support continuity of care for women with previous GDM, a group that has expressed discontent about fragmented care and little opportunity to receive elaboration on health risks and recommendations [Drawing on the unique possibility offered by Denmark’s civil registration number system to link individual data across multiple nationwide registers, our simple intervention design enabled us to identify and recruit participants, despatch the reminders, and assess outcomes without causing any significant disturbances for current practices. This ensured sufficient recruitment and retention rates with no loss to follow-up, a frequent challenge to the feasibility of executing interventions studies [Reflection on coverage of an intervention in a specific service setting gives indications of its integration [However, as poor communication across sectors and GP clinics’ insufficient information on risks and recommendations may challenge participation in follow-up screening [
