Administrative intervention to support testing after gestational diabetes and hypertensive disorders in pregnancy

The intervention consists of personalised administrative assistance to attend the recommended postpartum 6-week GP review and undergo recommended postpartum testing after gestational diabetes (GDM) and hypertensive disorders of pregnancy (HDP) in keeping with current recommendations. This will include: 1. Booking the appointment with the participant's GP at a day and time of their choosing 2. Provision of pathology forms for oral glucose tolerance test (OGTT) (if GDM); and for 24 hour blood pressure monitor, urinary protein:creatinine ratio and blood tests for fasting lipids and glucose (if HDP). 4. Booking of OGTT (if GDM) at pathology centre of participant's choice at 12 weeks postpartum. The participant will be provided with a single page summary of the appointments. The personalised administrative assistance is provided by the PhD student investigator on the study team. This is provided either at or after 36 weeks for those recruited antenatally, and within one week postpartum for those recruited postpartum. Fidelity to the intervention will be assessed primarily at the four month survey for all participants. A subset will also undergo validation by correspondence with the participant's GP, for those who provide consent to do so during the participant recruitment and consent process. Validation involves the following: no active participation from participants. Contact with consenting participants' primary care practitioner will be performed for this subset, and data on a. whether a six week visit was performed; b. whether an OGTT or other diabetes screening test has been performed postpartum, and when (for those with GDM); and c. whether additional testing after hypertensive disorder in pregnancy has been performed, and which tests these are. The timing of this subset validation will be: six months postpartum, i.e. two months following the participant's four month survey.
