Study type
Description of intervention(s) / exposure
The specific intervention for this trial is in the use of a smart phone and internet based app. The app will enable women with a diagnosis of gestational diabetes mellitus to enter their recorded blood sugar levels into the app on their smart phone. This will be used in lieu of a paper diary. Clinicians providing care to the patient will be able to view the blood sugar levels on a regular basis through an online portal. This reduces the number of time the woman is required to present to the hospital to provider her blood sugar levels to the clinicians. Any intervention required based on the levels are still able to be made through direct contact with the patient and the Diabetes Educator. Intervention will be determined by the patients individual blood sugar levels and care tailored as required. Women will be required to use the app each time their blood sugar levels are taken through the course of a day. On average for a woman diagnosed with GDM blood sugar level readings are taken 3-4 times per day. Each patient is provided a plan for the monitoring of her blood sugar levels with the Diabetes Educator. Frequency is dependent on a number of contributors.
The app usage is monitored by the treating clinician and blood sugar levels reviewed weekly. Should the patient not enter their blood sugar levels into the app, she will be phoned by the diabetes Educator and regular outpatient visits to the antenatal clinic will be required.

Primary outcome [1] 322458 0
The composite primary endpoints include:
i. Uptake and usage of the M?THer App. This is monitored through the clinician portal.
ii. Acceptance of the App by women, and clinical portal by treating clinicians. Focus groups will be held with the patients and clinical staff to ascertain the benefits of the app and if it reached its primary outcomes.
iii. Perceptions on the impact of using M?THer on multidisciplinary care co-ordination by healthcare practitioners. This will be assessed through the abovementioned focus groups and participation questionnaires for patients and staff.

Secondary outcome [3] 379005 0
Frequency of antenatal contact and occasions of service attended by women, related to GDM. This is assessed by the number of physical hospital appointments attended. Appointments are scheduled in the integrated electronic medical record (ieMR) and clinical notes recorded for each visit. Clinical notes will also be recorded by the reviewing clinician in the ieMR when reviewing sugar levels in the app.

Statistical methods / analysis
Women recruited into the study who opt to use the M?THer app will receive usual care as well as access to the M?THer App. Usual care varies at the different study sites and local procedures will be considered during recruitment, patient monitoring and follow-up. The women will be assisted on downloading the App from the Apple App Store or the Google Play Store and automatically receive login details as soon as they are registered through the Clinician Portal. A video embedded in the App will guide the women on the use of all its features. In addition, all participants will be provided with an illustrated user manual.
All women who consent to participate in the study will be provided with a link to the research trial software, RedCap, and through the software be invited to complete a short satisfaction survey at 4 weeks after commencement on the M?THer App and again within two weeks post their gestational period. All women will be advised to regularly test their BGL’s as per clinical guidelines.

Brief summary
Gestational Diabetes mellitus (GDM) is becoming more common in Australia, affecting thousands of pregnant women. Between 12% and 14% of pregnant women will develop GDM, with diagnosis usually occurring around the 24th to 28th week of pregnancy. Scientific evidence shows that controlling glucose levels can result in reduced risk of foetal complications (such as macrosomia) and increased maternal quality of life. However, due to increasing rates, and earlier diagnosis of GDM, and a number of systemic (associated increased health care costs, finite economic and staffing resources;) and patient barriers (non-adherence to blood glucose level (BGL) testing as per clinical guidelines; inconvenience in attending clinic visits), impediments to optimal maternal health exist.

The project aims to evaluate the real-world implementation of a smartphone- and Internet-based interactive system (called M?THer) to support women with diagnosis of GDM. The project will evaluate the adoption and acceptability of the platform, as well as the impact of using the system on service delivery. The project will implement and evaluate a previously piloted and enhanced M?THer system at Metro South Health Antenatal Services (including Redland, Logan and Beaudesert Hospitals) as well as at the Mater Mother’s Public Hospital.
