Background and study aims
Even though many pregnant women in Malawi and Zambia receive regular healthcare during pregnancy and give birth in health centres, there are still many women who die from complications during childbirth. We have reliable evidence that these maternal deaths can be prevented with good quality healthcare that follows the guidance of the World Health Organisation (WHO). The WHO recommend that all pregnant women have regular health visits during pregnancy; the WHO also recommends that healthcare staff perform specific checks during each pregnancy visit so that any problems during pregnancy are found and treated before they become life-threatening to women or their babies.
This study will look at the healthcare pregnant women receive during their pregnancy and when they give birth in primary health centres in Malawi and Zambia. The researchers will compare important events during pregnancy and birth in facilities where staff provide women with standard pregnancy care versus those same important events in facilities where staff deliver an improved pregnancy healthcare service. The improved pregnancy health services include training for staff and pregnant women and supplies for health facilities.

Who can participate?
This study will include health facilities rather than individuals. The health centres will have 700 - 2000 visits per year from pregnant women. The health centres will also be able to provide emergency pregnancy care, provide services for free to pregnant women, and complete an assessment process to ensure that the site is ready for the trial.

What does the study involve?
The study will start with a baseline phase, where the researchers will measure key events during pregnancy and childbirth. Next, the facilities will be randomly assigned to either continue providing their standard pregnancy care with basic supplies or to deliver the study intervention to improve pregnancy care, with training for staff and pregnant women and with basic supplies.

What are the possible benefits of participating?
The researchers expect that the health centres receiving the study intervention to improve pregnancy will be better able to provide care that meets WHO standards. They expect these health facilities to have better results for women and babies in terms of avoiding complications during pregnancy that lead to preventable deaths amongst women.

Where is the study run from?
This study is run from the Malawi Liverpool Wellcome Institute in Blantyre (Malawi) and from Lusaka Apex Medical University in Lusaka (Zambia). The study teams also have support from the University of Liverpool (UK).

When is the study starting and how long will it run for?
August 2022 to July 2026

Scientific titleThe enhanced antenatal care bundle to improve maternal and newborn outcomes in pregnant women attending maternity health services in Malawi and Zambia: a multi-country, parallel cluster-randomised trial
Study acronymENHANCE
Study objectivesENHANCE will provide a comprehensive bundle of measures carefully developed for primary health centres in resource-limited settings, to support the consistent and comprehensive delivery of all aspects of antenatal care according to WHO guidelines. ENHANCE includes tools, leadership, mentorship, task shifting and basic antenatal care supplies.

This study will determine whether an ENHANCE strategy compared with standard antenatal care is acceptable to pregnant women and healthcare staff; whether ENHANCE improves the implementation of antenatal care services according to WHO guidance; and whether ENHANCE improves both the quality of antenatal care and the maternal and neonatal clinical outcomes for women and babies who receive the intervention.

Health condition(s) or problem(s) studiedDelivery of antenatal care services
InterventionThe study will implement a package designed to improve the quality and content of antenatal care delivered in resource-limited settings and compare this with the standard antenatal care offered to pregnant women in Malawi and Zambia.

This is a multi-country, parallel cluster-randomised controlled trial with a baseline period. There is an integrated implementation evaluation and health economic evaluation. The trial will include primary healthcare centres in Malawi and Zambia as clusters. During the first 3 months each cluster will provide standard care to establish weekly rates of maternal and newborn outcomes. After the baseline, the clusters will be randomly allocated in a 1:1 ratio to ENHANCE or standard care with the provision of basic ANC supplies, using a minimisation algorithm to account for the imbalance in location, hospital deliveries volume and distance to referral facility. Both quantitative and qualitative approaches will gather the data required to meet the objectives. The researchers will conduct an intention-to-treat analysis of the composite primary outcome. Descriptive statistics for continuous (mean and standard deviations), discrete (median and range or interquartile range) and categorical (frequency counts and percentages) variables will summarize baseline characteristics (demographic and clinical data) and outcome variables. Process evaluation surveys will be summarised using descriptive statistics as appropriate, and responses compared across PHCs and countries. Interviews will be analysed using combined deductive framework and inductive thematic analysis.
