Planned early delivery for late preterm pre-eclampsia in a low- and middle-income setting: a feasibility study

Background Pre-eclampsia is a leading cause of maternal and perinatal mortality and morbidity globally. Planned delivery between $ 34^{+0} $ and $ 36^{+6} $ weeks may reduce adverse pregnancy outcomes but is yet to be evaluated in a low and middle-income setting. Prior to designing a randomised controlled trial to evaluate this in India and Zambia, we carried out a 6-month feasibility study in order to better understand the proposed trial environment and guide development of our intervention. Methods We used mixed methods to understand the disease burden and current management of pre-eclampsia at our proposed trial sites and explore the acceptability of the intervention. We undertook a case notes review of women with pre-eclampsia who delivered at the proposed trial sites over a 3-month period, alongside facilitating focus group discussions with women and partners and conducting semi-structured interviews with healthcare providers. Descriptive statistics were used to analyse audit data. A thematic framework analysis was used for qualitative data. Results Case notes data (n = 326) showed that in our settings, 19.5% (n = 44) of women with pre-eclampsia delivering beyond 34 weeks experienced an adverse outcome. In women delivering between $ 34^{+0} $ and $ 36^{+6} $ weeks, there were similar numbers of antenatal stillbirths [n = 3 (3.3%)] and neonatal deaths [n = 3 (3.4%)]; median infant birthweight was 2.2 kg and 1.9 kg in Zambia and India respectively. Lived experience of women and healthcare providers was an important facilitator to the proposed intervention, highlighting the serious consequences of pre-eclampsia. A preference for spontaneous labour and limited neonatal resources were identified as potential barriers. Conclusions This study demonstrated a clear need to evaluate the intervention and highlighted several challenges relating to trial context that enabled us to adapt our protocol and design an acceptable intervention. Our study demonstrates the importance of assessing feasibility when developing complex interventions, particularly in a low-resource setting. Additionally, it provides a unique insight into the management of pre-eclampsia at our trial settings and an understanding of the knowledge, attitudes and beliefs underpinning the acceptability of planned early delivery..

Plain language summary Pre-eclampsia is a complication of pregnancy and is one of the major causes of pregnancy-related death and serious illness for women and babies around the world. Most of these deaths occur in lower income countries in Africa and Asia. Signs of pre-eclampsia include high blood pressure and protein in the urine. It is unpredictable and may affect different organs within the woman, leading to seizures, stroke and even death if not well managed. It can also affect the baby’s growth and in severe cases lead to stillbirth. We know that birth of the baby (and placenta) is the only cure for pre-eclampsia. Currently, it is recommended by the World Health Organisation that all women with pre-eclampsia are offered planned early birth once they reach 37 weeks of pregnancy, unless they develop severe complications needing intervention sooner than this. However, research from higher income countries has shown that planned early birth from 34 weeks of pregnancy may reduce serious complications in the woman, without causing harm to the baby. We are designing a clinical trial to find out whether, in women with pre-eclampsia between 34 and 37 weeks of pregnancy, it is better to offer planned early birth or to offer close monitoring until either they reach 37 weeks, or a complication develops requiring emergency intervention. Before designing this trial, we carried out a study in order to establish whether the main trial would be possible, and acceptable to the local community, at our potential trial sites in India and Zambia..
