Improving women's lifelong health after high-risk pregnancy

Cardiovascular diseases (CVDs), such as strokes and heart attacks, are the leading causes of death amongst women globally. A particular group of women at high risk of cardiovascular disease are those who experience a pregnancy complicated by gestational diabetes mellitus (GDM) and/or a hypertensive disorder of pregnancy (HDP). Following a pregnancy affected by GDM, within 5-years up to 50% of women will develop T2DM; and following HDP, 30% of women will develop hypertension.

Both these conditions greatly increase risk for CVD, however with timely detection and management these risks can be greatly reduced. The importance of breaking this link between high-risk pregnancy and CVD is widely acknowledged, yet to date there have been no trials demonstrating this can be achieved, and importantly whether it can be done affordably and at scale.

Three key actions are needed: (i) effective primary prevention; (ii) regular screening, and (iii) evidence-based management when disease is detected.

India is experiencing an epidemic of type 2 diabetes mellitus (T2DM) and hypertension. 73 million people have diabetes, and 207 million hypertension (2017 data). Rates of GDM and HDP are high, affecting 20% and 10% of pregnancies, respectively. There is an urgent need for effective and affordable preventative strategies to reduce the economic, social and health consequences of these conditions for women in India.

In the UK, GDM and HDP are the commonest complications of pregnancy. After a pregnancy with GDM, women should undergo screening with their GP 6 week after birth for persistent high blood glucose. Attendance however is generally poor, with rates between 30-70% across the country. Following HDP, evidence is needed to guide care.

The Fellowship will enable me to lead connected programs of work across two countries: India and the UK, determining the role digital innovations could play to deliver post-partum interventions in women globally. I will conduct two clinical studies, with active engagement with policy makers, clinicians, digital health companies and social enterprises throughout the Fellowship.

SMART Health is a digital platform, developed by the George Institute for Global Health, that has been implemented in India, Indonesia, China, and Myanmar, to improve detection and management of diabetes and hypertension. The platform is aimed at rural community health workers and primary care doctors, enabling task shifting, clinical decision support, automated referral, SMS reminders, and patient tracking.

Since 2017, I have been leading the group adapting this platform to improve the detection and management of anaemia, GDM and HDP in pregnant women living in rural India: SMART Health Pregnancy (SHP). Through this Fellowship I will extend SHP to facilitate prevention, screening, and early treatment of hypertension and T2DM in the years after a pregnancy complicated by GDM and/or HDP.

The effect of this on achieving target blood pressure and blood glucose control after high risk pregnancy will be assessed in a large clinical trial in rural India, following 960 women for 5-years.

In the UK, I was part of the team of clinicians and researchers in Oxford who developed a remote monitoring system for women with GDM (GDmHealth). We demonstrated in a clinical trial that this approach was safe, convenient and preferred by women and health workers. The technology was licensed to a commercial company (Sensyne) in 2018, and since then thousands of women have benefited from this innovation across the UK.

Through this Fellowship I will lead a program of work adapting this approach for women in the year after birth, assessing whether remote monitoring improves screening attendance, deliver effective lifestyle support, offer a potential cost savings to the NHS, whilst being acceptable and more convenient for new mums. Theis approach could improve their health, for future pregnancies and lifelon
