Description of intervention(s) / exposure
This study of women diagnosed with Gestational Diabetes Mellitis (GDM) will investigate the feasibility, acceptability and patient satisfaction with the use of the Net-Health smartphone application (app).
The app will collect baseline information at time of registration including age, ethnicity, family history of type 2 diabetes, height, pre pregnancy weight, gestational weight gain, gestation, number of previous pregnancies and previous GDM (including type of treatment).
After registration, the mobile app will be linked via bluetooth to the blood glucose meter and used to transfer fingerprick BGLs automatically to a secure central server for remote monitoring by the treating team.
The app contains some instructions about its use and women will have direct contact details for the diabetes educators if there are any questions about its use. It has the capacity to transfer blood pressure (BP) results from linked home BP machines.
The Net-Health server will notify the treating team if 3 or more BGLs are out of range within 1 week via an automatically generated email to prompt expedited phone or clinic review.
Duration of the intervention will be from time of consent (after diagnosis between 24-30 weeks gestation) to and will cease after delivery.
Adherence will be assessed at clinic appointments with the number of BGL's reviewed and at completion of the study with number of BGL's submitted (compared with expected 4 per day from consent to delivery). Text reminders may be sent at routine follow up of BGL's at prespecified time points in care.

Treatment: Devices
Comparator / control treatment
We will generate a historical control group containing 100 women with GDM matched for type of treatment required. These will be identified from hospital records of women attending the group education session in January 2017 to January 2018 and may incorporate data from a current database of women with GDM.

Outcomes
Primary outcome [1] 320722 0
To assess the feasibility of the Net-Health software application for blood glucose monitoring in a group of patients with gestational diabetes mellitus (GDM) in a tertiary hospital setting.
Feasibility for the diabetes service will be assessed by the occasions of service to determine workload on the diabetes service. These include clinic, phone or email reviews as well as messages sent to or received from the participant via the app.
Timepoint [1] 320722 0
Four months post enrollment (post delivery - maximum of 18 weeks post enrollment given earliest gestation of inclusion 24 weeks and latest delivery 42 weeks).
Primary outcome [2] 320723 0
To assess the acceptability and patient satisfaction with the Net-Health software application using a validated questionnaire to be completed in the peri/post-partum period. The questionnaire is 'The Oxford Maternity Diabetes Treatment Satisfaction Questionnaire '(OMDTSQ) which has been developed to assess satisfaction of women with GDM care, technology and the perceived relationship with their diabetes team and validated in this population.
Timepoint [2] 320723 0
Four months post enrollment (post delivery - maximum of 18 weeks post enrollment given earliest gestation of inclusion 24 weeks and latest delivery 42 weeks).
Primary outcome [3] 320724 0
To determine the health resource utilisation as assessed by data linkage to medical records including occasions of service by the diabetes team.
Timepoint [3] 320724 0
Four months post enrollment (post delivery - maximum of 18 weeks post enrollment given earliest gestation of inclusion 24 weeks and latest delivery 42 weeks).
Secondary outcome [1] 372615 0
To determine mean weekly blood glucose level as assessed by app analytics.
Timepoint [1] 372615 0
Four months post enrollment (post delivery - maximum of 18 weeks post enrollment given earliest gestation of inclusion 24 weeks and latest delivery 42 weeks).
Secondary outcome [2] 372616 0
To assess a composite of neonatal outcomes (assessed by data linkage to medical records and perinatal data collection application) including:
- gestation at and mode of delivery
- birthweight
- neonatal complications (including shoulder dystocia, neonatal hypoglycaemia, jaundice and requirement for higher level nursery care)
Timepoint [2] 372616 0
Six months post enrollment
