The PRECISE (PREgnancy Care Integrating translational Science, Everywhere) Network’s first protocol: Deep phenotyping in three sub-Saharan African countries

listen audio

Study Justification:
The PRECISE Network’s first protocol aims to investigate the social determinants of health, demographic and clinical parameters, placental biology, and agnostic discovery biology in pregnant women in sub-Saharan African countries. The study seeks to understand how these factors interact and contribute to either a resilient or compromised pregnancy outcome for both mother and fetus/newborn. By deep phenotyping women throughout pregnancy and the postpartum period, the study aims to generate a comprehensive understanding of pregnancy complications and their implications for maternal and child health. This knowledge is crucial for achieving the Sustainable Development Goals related to women’s and children’s health.
Highlights:
– The study will recruit non-pregnant women of reproductive age and pregnant women from three sub-Saharan African countries: The Gambia, Kenya, and Mozambique.
– A total of 600 non-pregnant women and approximately 10,000 pregnant women will be recruited over a period of 2 years.
– The study will collect a wide range of data, including social, demographic, clinical, and biological information, to create highly-phenotyped representative cohorts of African women.
– The protocol includes the use of innovative tools and technologies, such as the TraCer app for accurate gestational age dating and the CRADLE VSA device for blood pressure measurements.
– The study will also establish a biorepository for future hypothesis-generated and generating research.
Recommendations:
– The study recommends further funding to maintain the cohort and expand the research to include intervention studies for pregnant and postpartum women and their offspring.
– The findings from this study will inform clinical improvements and interventions to improve maternal and child health outcomes in sub-Saharan Africa.

Background: The PRECISE (PREgnancy Care Integrating translational Science, Everywhere) Network is a new and broadly-based group of research scientists and health advocates based in the UK, Africa and North America. Methods: This paper describes the protocol that underpins the clinical research activity of the Network, so that the investigators, and broader global health community, can have access to ‘deep phenotyping’ (social determinants of health, demographic and clinical parameters, placental biology and agnostic discovery biology) of women as they advance through pregnancy to the end of the puerperium, whether those pregnancies have normal outcomes or are complicated by one/more of the placental disorders of pregnancy (pregnancy hypertension, fetal growth restriction and stillbirth). Our clinical sites are in The Gambia (Farafenni), Kenya (Kilifi County), and Mozambique (Maputo Province). In each country, 50 non-pregnant women of reproductive age will be recruited each month for 1 year, to provide a final national sample size of 600; these women will provide culturally-, ethnically-, seasonally-and spatially-relevant control data with which to compare women with normal and complicated pregnancies. Between the three countries we will recruit ≈10,000 unselected pregnant women over 2 years. An estimated 1500 women will experience one/more placental complications over the same epoch. Importantly, as we will have accurate gestational age dating using the TraCer device, we will be able to discriminate between fetal growth restriction and preterm birth. Recruitment and follow-up will be primarily facility-based and will include women booking for antenatal care, subsequent visits in the third trimester, at time-of-disease, when relevant, during/immediately after birth and 6 weeks after birth. Conclusions: To accelerate progress towards the women’s and children’s health-relevant Sustainable Development Goals, we need to understand how a variety of social, chronic disease, biomarker and pregnancy-specific determinants health interact to result in either a resilient or a compromised pregnancy for either mother or fetus/newborn, or both. This protocol has been designed to create such a depth of understanding. We are seeking funding to maintain the cohort to better understand the implications of pregnancy complications for both maternal and child health.

This phase of the planned PRECISE initiative is a prospective observational cohort design. Where health issues are identified for individual women and newborns, then they will be referred into existing health system pathways. The funding mechanism for this cohort study specifically precluded clinical trials, enforcing the purely observational design. Once biomarker data become available for women after the clinical phase is completed, important clinical data (e.g., hyperglycaemia) will be provided to women and their caregivers. We are seeking further funding to begin intervention studies for pregnant and puerperal women, and their offspring, in these communities (e.g., stepped-wedge cluster randomised controlled trials). The PRECISE sites have been chosen in locations with research excellence and where data collection will produce representative cohorts of West, East and Southern African women. Given the transition towards increasingly urban populations in Africa and elsewhere in less-developed countries, PRECISE has been designed to recruit women living in both urban and rural settings in the three geographies (Figs. ​(Figs.2,2, ​,33 and ​and44). Gambian sites Kenyan sites Mozambican sites Specific variations on protocol implementation were made to respond to individual country scientific and ethical review boards’ recommendations. To maximise the quality of the biorepositories, each country’s selection of sites was undertaken to ensure rapid access to definitive biorepository facilities. Our primary partner in The Gambia is the MRC Unit The Gambia at LSHTM. The field research will occur at the Farafenni Hospital (urban hospital) and associated rural primary health centres (PHCs) in Illiasa and Ngayen Sanjal; these health facilities cover a population under demographic surveillance since the 1980s. Our primary partner in Kenya is the Aga Khan University (East Africa) (AKU). The field research will be conducted through the Mombasa field station, with field activity in Mariakani Subcounty Hospital (urban) and Rabai Health Centre (rural). Our primary partner in Mozambique is the Centro de Investigação de Saúde de Manhiça (CISM). The field research will occur in the Manhiça District Hospital (primarily urban population) and Xinavane Rural Hospital (primarily rural population), with some laboratory activity at Eduardo Mondlane University, Physiological Science and Pathology Departments in Maputo. While PRECISE is designed to answer specific research questions, a major legacy will be the highly-phenotyped representative cohorts of West, East and Southern African women and the creation of an incomparable Africa-based biorepository for future hypothesis-generated and generating research. The core activity will be to collect environmental, social, geographical, demographic, clinical and biological data related to three populations of women. Specific details of the planned cohorts are provided below. The PRECISE Network clinical sites have been working in these communities for many years and have built strong relationships of trust with their communities. The local PRECISE leadership and study teams have informed participating communities of the study and, particularly, had in-depth discussions on the best approach within a given community for the collection of samples that may have cultural or religious significance such as maternal blood, cord blood and placental samples. In addition, the team has discussed with communities the best approach for collecting specimens immediately following childbirth (cord blood and placental tissue) and will return the placenta to the family (if that is their wish) after it is weighed and photographed, and small samples are taken from it. Community engagement activities will be conducted in all study sites to ensure the women and communities in which they live are aware of the PRECISE programme of work. A brief overview of planned activity is presented in Table 1. Community engagement Faith leaders Non-religious community leaders Women attending antenatal clinic (ANC) Community leaders Pregnant women Women of reproductive age Mothers and mothers-in-law Partners Stakeholders (Ethical committees, investigators, policy makers) Nurses Health care workers Community leaders Community health volunteers (CHV) Community-wide meetings Pregnant women, partners, family members Go out into the community to engage with community leaders Open days at health facilities to explain to the women attending ANC Health talks in the health facility Community meetings Informal conversations Discussion boards Health talks (baraza) or videos on loop at ANC Community meetings (this will tag on to existing community-based meetings) Additional community meetings may be convened for target audiences (pregnant women, mothers, other in-laws, partners) Introduction to research Introduction to informed consent When/how/why storing biological samples Assess the acceptability of the biorepository Promote early disclose of pregnancy and early attendance to the ANC visits. Promote birth preparedness and hospital delivery Identification of a health unit to give birth in Identification of skilled birth attendants Introduction to research Introduction to informed consent When/how/why storing biological samples Sensitisation activities will occur before recruitment starts and continue during the recruitment period At the end of the study, we will communicate the results to the community following the same procedures Health talks will be conducted twice a week during the morning with pregnant women in the health facility In the community meetings with specific groups will be conducted One meeting per month with the stakeholders Initiate activities 2 months before data collection. Activities will be heightened in communities closest to the health facilities as they will have the largest number of women from these areas Activities will occur throughout the study. Each community will be approached roughly once per month Women enrolled in the PRECISE study will have an opportunity to read or be read the informed consent in their native language and to ask any questions they may have. Consent will be confirmed with the participant’s signature or a thumbprint. In the absence of a signature, a witness (other than the member of the research team obtaining consent) will be asked to sign. Finally, the member of the research team obtaining consent will sign the form. For recruitment of women aged 14 - 17 years old, the consent and assent processes will be guided by in-country ethics boards. We will request tiered consent, whereby women will be asked to provide general consent, as well as specific vaginal swab consent, genetic study consent, the sharing of samples between African sites, the sharing of data and samples beyond Africa, and the sharing of data and samples with industry. It is specified that samples are only being taken for research purposes and will have no impact on their clinical care. The informed consent documents permit future research related to pregnancy and birth and their complications. This study involves pregnant women and newborns. In most sites, potential participants do not speak English. In these sites, consent will be taken in the local language to ensure that the potential participant understands the research. Every effort will be made to ensure their voluntary participation. It will be explained that participation is voluntary and can be terminated at any time without reason and without any penalty. If the potential participant has any questions, they will be answered in their native language to ensure that they understand the research and their potential role in it. To ensure privacy, consenting will take place in a private room at the local health facilities. Hard copies of any study-related forms, e.g. patient logs, will be stored in a locked cabinet in a storage room under supervision of the principal investigators (and destroyed after entering the database and performing the relevant quality control checks performed through the monthly data monitoring reports). Electronic records will be stored in password-protected computers and tablets and only approved study personnel will have access to entire level of information (e.g. laboratory technicians will have access only to a subset of data, thus reducing the risk for a major level breach). Access to the entire dataset will be restricted to the main PI and the site PIs, to keep a strict control of the data. All specimens and associated phenotypic data will be de-identified and given a unique participant identifier code and no personal information will be stored in the data management systems. As described, the PRECISE research programme will collect 360° data that place women in their social, geographic, health services, nutritional and chronic disease contexts, as well as collecting important biophysical and biomarker data that will explain risks for, and pathways to, placental disorders and other complications of pregnancy. Details of the data fields being collected are in the complementary database paper [2]. Using mixed methods, we will assess women in terms of their beliefs and practices around pregnancy, access to care and the acceptability of novel diagnostic tools and interventions. Similarly, we will assess these factors in men’s groups, mothers and mothers-in-law, faith and community leaders, and health service providers and administrators. Much of this work has already been completed in Mozambique during the CLIP trial feasibility study [3–6]. This activity will be supplemented in Mozambique and replicated in The Gambia and Kenya. Additional details are provided in the qualitative methods paper [7]. Non-clinical data will relate to their nutritional status, demographics and women’s natural and built environment, this includes data on the women’s home including the structure, building materials, proximity to a toilet as well as the environment including cooking facilities and water availability. In addition, we will capture data on available health services (and an assessment of the quality of care provided by them). All data will be entered into the PRECISE data platform. These data will largely be collected during the enrolment visit for all women, whether non-pregnant or pregnant. Clinical data will be collected using an electronic data collection platform with the additional PRECISE data fields. At enrolment, these data will include limited information about past obstetric, medical, and surgical history for all women. For pregnant women, best estimates of pregnancy dating will be obtained at the first visit. At all visits, women will have their weight, blood pressure (BP) and SpO2 measured. Full details on the data being captured are outlined in the database paper [2]. Specific clinical tools to be tested and validated within PRECISE include: (i) the TraCer (transcerebellar diameter) app that will date all pregnancies using the highly-conserved and growth restriction-resistant transcerebellar diameter (separate in-country, sub-project-specific ethics approval for the development and utility testing of the app has been granted) (pregnancy only); (ii) the CRADLE VSA semi-automated and validated BP device will be used for all clinical measurements of blood pressure (BP) in the study [8–14] (non-pregnancy and pregnancy); (iii) pulse oximetry will be used to assess the impact of cardiorespiratory disease [15–21] (non-pregnancy, pregnancy and neonates); (iv) the PIERS On the Move (POM) platform to provide time-of-disease risk estimates to hypertensive pregnant women using the PIERS (Pre-eclampsia Integrated Estimate of RiSk) models [15, 22–35] (non-pregnancy and pregnancy); and, possibly, (v) WOICE, the WHO Maternal Morbidity Working Group Tool [36–39] at visits in the third trimester. Standards for the use of the CRADLE BP device, pulse oximetry and TraCer platform will be detailed in the relevant portions of the clinical SOP. In all countries, women aged 18 years old or older can provide informed consent for research, and pregnant women aged 16 and 17 years old can provide informed consent. In Mozambique, pregnant women aged 14 and 15 years old can provide assent for research with consent provided by a custodial adult. The Department of Health in Kilifi Country has asked us to replicate this in their jurisdiction, and the required ethical amendments are in progress. For all cohorts, we have set an upper age limit at 49 years of age. We will exclude any women who have already been approached and declined participation in PRECISE. Flow and sampling of nonpregnant women of reproductive age In each country, 50 women will be recruited each month for 1 year, to provide a total national sample size of 600 non-pregnant women of reproductive age. These women will provide culturally, ethnically and spatially-relevant control data with which to compare women with normal and complicated pregnancies (PRECISE Objective 2b). Recruitment will occur throughout the year to provide seasonal data, with the associated fluctuations in geographical (due to seasonal migration) and infectious disease burdens of risk. These women will be approached either in the community (in The Gambia) or when attending the facility for the care of someone else (e.g. for infant vaccinations) or for their own care (family planning assessment) (Mozambique and Kenya), and asked to provide data and samples at a single time point. Non-clinical and clinical data as well as biological samples will be collected during the first year of the clinical phase of the project. At the encounter, consenting women will be asked to provide: Flow and sampling of unselected pregnant women We are aiming for approximately 10,000 women to be recruited to this cohort across the three countries. These women will be approached when visiting the clinic for antenatal care and will be asked to provide data and biological samples to derive normative ranges for pregnant women in less-developed countries (PRECISE Objective 2b). We will recruit women age 14*- 49 years-old (*as pregnant adolescents are at increased risk of placental disease) [40]. For recruitment of women aged 14 – 17 years old we will be guided by the consent and assent processes advised by in-country ethics boards. Research partners in the study countries have advised that pregnant women aged 16 years and over will not require parental consent to participate but can provide consent themselves. It is anticipated that the median gestational age at booking in each country will be about 24–27 weeks of pregnancy (unpublished data from the Community-Level Interventions for Pre-eclampsia [CLIP] trials). Whenever possible, at the booking visit women will be approached for participation. Consenting women will have their pregnancies dated using, in order of accuracy, ultrasound dating (recognised to be very uncommon in these settings), certain last menstrual period, estimated last menstrual period and symphysis-fundal height (supplemented, for study purposes, by the ultrasound-based transcerebellar diameter (TraCer) device that determines gestational age using the highly-conserved transcerebellar diameter [41]); the TraCer dating will be used as the gold standard for the academic enterprise. As the TraCer device does not yet have a CE mark it is not appropriate that these data be used to direct clinical care; however, if during the scan there are concerns about the fetus or pregnancy, the women will be referred down the standard clinical care pathway for further investigation. If TraCer is CE marked during the clinical phase of PRECISE, these data will then begin being shared with clinical teams. Thereafter, the women will be asked to provide: Should a woman not be identified and recruited at her booking visit (and not declined participation), she will be approached at her next visit and, if informed consent is obtained, she will be recruited into PRECISE and the above-described data and samples obtained. Between 28 weeks’ gestation and the onset of labour, and at least 4 weeks after the study recruitment visit, participating pregnant women will be asked to provide: Intrapartum, the following will be collected: Participating women will be asked to provide: Prior to discharge home, and up to 48 h postpartum, participating women will be asked to provide: In addition, permission will be requested to gather the following neonatal data and samples: At, or soon as possible after, 6 weeks postpartum, participating women will be asked to provide: In addition, permission will be requested to gather the following neonatal data and samples: Flow and sampling of pregnant women with suspected/confirmed placental disease Cohort 3 will include women who have pregnancies complicated by pregnancy hypertension (systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg) or FGR (as suspected by the clinician undertaking their care). Cohort 4 includes women with who are either experiencing an intrauterine fetal death or who have delivered a stillborn infant. These women will be approached when visiting the clinic for antenatal care or if they have been referred for care due to suspected or diagnosed placental complications. We will recruit women age 14*-49 (*as pregnant adolescents are at high risk of placental disease). Research partners in the study countries have advised that pregnant women aged 16 and over will not require parental consent to participate but can provide consent themselves. With the first diagnosis of pregnancy hypertension ≥20+ 0 weeks, clinical suspicion of fetal growth restriction, or fetal death in utero, women will be approached for recruitment and consent. Health workers will be trained in appropriate and sensitive recruitment of women in the time-of-disease cohort, acknowledging the emotional distress that women may be feeling at this time. Consenting pregnant women will be asked to provide: Between 28 weeks’ gestation and the onset of labour, and at least four weeks after the study recruitment visit, participating pregnant women will be asked to provide: Intrapartum, the following will be collected: Participating women will be asked to provide: Prior to discharge home, and up to 48 h postpartum, participating women will be asked to provide: In addition, permission will be requested to gather the following neonatal data and samples: Prior to discharge home, and up to 48 h postpartum, participating women will be asked to provide: In addition, permission will be requested to gather the following fetal/neonatal data: At, or soon as possible after, 6 weeks postpartum, participating women will be asked to provide: In addition, permission will be requested to gather the following neonatal data and samples: At, or soon as possible after, 6 weeks postpartum, participating women will be asked to provide: Flow and sampling of women with stillbirths recruited postpartum For women who have been referred to the facility with IUFD and for whom it will not be possible or appropriate to approach and consent before delivery, consent to collect retrospective data and samples will be sought postpartum. We will recruit women age 14*-49 (*as pregnant adolescents are at high risk of placental disease) in the delivery suites of the PRECISE facilities. As for Cohorts 3 & 4, for recruitment of women aged 14 - 17 years old we will be guided by the consent and assent processes advised by in-country ethics boards. Research partners in the study countries have advised that pregnant women aged 16 and over will not require parental consent to participate but can provide consent themselves. Participating women will be asked to provide: Prior to discharge home, and up to 48 h postpartum, participating women will be asked to provide: At, or soon as possible after, 6 weeks postpartum, participating women will be asked to provide: Women are not offered incentives to attend the follow up visit, however, in The Gambia and Mozambique, if needed, transport will be arranged to bring the woman and her baby to the unit but no money is given. Sampling from Cohort 1 (non-pregnant women of reproductive age) Sampling from Cohort 2 (unselected pregnant women) and Cohorts 3 & 4 (women at time-of-disease) and their infants aCohorts 2 and 3 in Kenya only Sampling from Cohort 5 (women with stillbirth recruited postpartum) Plasma samples will be used for placental growth factor and nutritional status assessments. All samples will be stored for later use in discovery science using semi-agnostic proteomics, genomics, epigenomics and metagenomics. Cohort 1: We anticipate that each participant enrolled in the non-pregnant cohort will provide one blood sample to the PRECISE Study at the time of enrolment. The blood draw will be approximately 16 mL. Cohort 2 We anticipate that each participant enrolled in the pregnancy cohort will provide at least four blood samples to the PRECISE Study: one at booking; one later in pregnancy between 28+ 1–36+ 6 weeks’ gestation (at least 4 weeks after the initial biological sampling); one within 48 h postpartum and one at or after 6 weeks postpartum. Each blood draw will be approximately 16 mL (roughly equivalent to 1 tablespoon). Cohorts 3 & 4 We anticipate that each participant enrolled in the pregnancy at ‘time-of-disease’ cohort will provide from one to four blood samples to the PRECISE study, depending upon when they present with complications: one at enrolment; and/or one later in pregnancy between 28+ 1–36+ 6 weeks gestation (at least 4 weeks after the initial biological sampling); one within 48 h postpartum and one at or after 6 weeks postpartum. Each blood draw will be approximately 16 mL (roughly equivalent to 1 tablespoon). All blood collection is intended to qualify as minimal risk. The total volume and frequency, when considered in the context of the clinical encounter, will not exceed the following parameters (OHRP (45 CFR 46.110): Cohort 5: We anticipate that participants enrolled in the stillbirth cohort who are recruited postpartum will provide two blood samples to the PRECISE Study: one at enrolment and one at or after 6 weeks postpartum. Each blood draw will be approximately 16 mL (roughly equivalent to 1 tablespoon). Up to 20 mL of urine will be collected up to four times, at the same time the blood sample is collected for Cohorts 2, 3 and 4. For Cohort 1 (the Non-Pregnancy Cohort), one urine sample will be collected once at the time of enrolment. All samples will be stored for later use in discovery science using semi-agnostic proteomics and metagenomics. With explicit additional consent, mid-vaginal swabs will be collected at the booking visit and when the women present to deliver. For Cohort 1 (the Non-Pregnancy Cohort), vaginal swabs will be collected once at the time of enrolment. For cohort 5, we will not collect vaginal swabs. All samples will be stored for later use, primarily related to metagenomics to gain insights into the interaction between the vaginal microbiome and pregnancy, newborn and puerperal outcomes. After delivery of the baby, the umbilical cord is clamped and cut. The umbilical cord (including the cord blood within it) is generally discarded along with the placenta. After the cord is clamped and cut, the cord blood will be collected. The amount of cord blood drawn will be approximately 16 mL (roughly equivalent to 1 tablespoon). All samples will be stored for later use in discovery science using semi-agnostic proteomics, genomics and epigenomics. The placenta will be trimmed and weighed and photographed using a digital camera in a fixed position. Eight small coin-sized tissue samples will be taken from the placenta, five 5 mm-long sections taken from the cord and one strip of membrane. Four samples will be processed in formalin for histology and the rest will be flash frozen in liquid nitrogen for proteomic and metabolomic analyses. All samples will be stored for later use in discovery science correlating placental findings with clinical outcomes and the outputs from the ‘omics science platforms. Only if the cord blood collection is missed, 2–3 drops of blood for DNA will be collected from a heel stick prior to discharge from the facility. All samples will be stored for later use in discovery science using semi-agnostic proteomics, genomics and epigenomics. The stool will be collected to examine the newborn microbiome. The neonatal stool sample will be collected from the baby’s nappy at the 6 weeks postpartum follow-up visit. The samples will be collected, processed and stored in adherence to the PRECISE Network biorepository standard operating procedures (SOPs) across all sites. Study personnel at each site will receive initial and ongoing training as needed to ensure SOPs are followed and samples are of the highest quality. As PRECISE will improve the quality of antenatal care provision, with accurate blood pressure measurement, a focus on stillbirth, and routine pulse oximetry, the research team recognises that defined clinical responses are incumbent on us, primarily through referral into existing clinical pathways. We are determining if and how to add mental health elements to the protocol through qualitative research. An important piece of prior work is to identify the clinical pathways for women identified with mental health emergencies. Academic co-ordination and general oversight are shared between the central PRECISE teams located at KCL and UBC. In-country clinical co-ordination is supplied by the research teams located in Farafenni (The Gambia), Mombasa (Kenya) and Manhiça (Mozambique), with central support in Fajara and Nairobi, in The Gambia and Kenya, respectively. Details of the monitoring and quality assurance plans are included in the database and biorepository papers (Craik R, et al.: Baobab Laboratory Information Management System, submitted). Our two principal analytical approaches will be to identify factors that predict the onset of placental disorders and factors that identify women, fetuses and newborns at incrementally increased risk at time-of-disease with pregnancy hypertension and FGR. We will prioritise modifiable factors to accelerate clinical improvements. The detailed statistical plan is being developed and will be published in due course.

The PRECISE (PREgnancy Care Integrating translational Science, Everywhere) Network’s first protocol aims to improve access to maternal health by conducting a prospective observational cohort study in three sub-Saharan African countries (The Gambia, Kenya, and Mozambique). The study will collect comprehensive data and biological samples from women throughout pregnancy and the postpartum period to better understand the social, demographic, clinical, and biological factors that contribute to normal and complicated pregnancies. The study will also assess the acceptability of novel diagnostic tools and interventions and engage with the community to ensure awareness and understanding of the research. The collected data and samples will be used for future hypothesis-generated and generating research to improve maternal and child health.
AI Innovations Description
The recommendation to improve access to maternal health based on the provided description is the development of the PRECISE (PREgnancy Care Integrating translational Science, Everywhere) Network’s protocol. This protocol aims to gather comprehensive data on women’s health during pregnancy and the postpartum period, including social determinants of health, demographic and clinical parameters, placental biology, and agnostic discovery biology. The protocol involves recruiting women from three sub-Saharan African countries (The Gambia, Kenya, and Mozambique) and collecting data and biological samples at various stages of pregnancy and postpartum. The data collected will be used to better understand the factors that contribute to both normal and complicated pregnancies, with the goal of improving maternal and child health outcomes. The protocol also includes community engagement activities to ensure that the women and communities involved are aware of the study and its goals. The development of this protocol is a crucial step towards developing innovative interventions and improving access to maternal health in these regions.
AI Innovations Methodology
Based on the provided information, here are some potential recommendations for innovations to improve access to maternal health:

1. Mobile Health (mHealth) Applications: Develop and implement mobile applications that provide pregnant women with access to information and resources related to maternal health. These apps can provide guidance on prenatal care, nutrition, and common pregnancy complications. They can also offer reminders for appointments and medication adherence.

2. Telemedicine Services: Establish telemedicine services that allow pregnant women in remote or underserved areas to consult with healthcare professionals remotely. This can help overcome geographical barriers and provide timely access to prenatal care and medical advice.

3. Community Health Workers: Train and deploy community health workers who can provide basic prenatal care, health education, and support to pregnant women in their communities. These workers can also facilitate referrals to healthcare facilities for more specialized care.

4. Maternal Health Vouchers: Implement voucher programs that provide pregnant women with financial assistance to access maternal health services. These vouchers can cover costs related to antenatal care, delivery, and postnatal care, ensuring that financial constraints do not prevent women from seeking necessary care.

5. Transportation Support: Develop transportation initiatives that address the challenge of accessing healthcare facilities. This can include providing transportation vouchers or arranging transportation services for pregnant women to attend antenatal visits and deliver their babies in healthcare facilities.

To simulate the impact of these recommendations on improving access to maternal health, a methodology could include the following steps:

1. Define the target population: Identify the specific population that will benefit from the innovations, such as pregnant women in rural areas or low-income communities.

2. Collect baseline data: Gather data on the current state of maternal health access in the target population, including metrics such as the percentage of women receiving antenatal care, the percentage of facility-based deliveries, and maternal mortality rates.

3. Define indicators: Determine key indicators that will be used to measure the impact of the innovations, such as the increase in antenatal care coverage or the reduction in maternal mortality rates.

4. Simulate the implementation of innovations: Use modeling techniques to simulate the implementation of the recommended innovations. This can involve estimating the potential reach and adoption of mHealth applications, telemedicine services, or other interventions.

5. Estimate impact: Based on the simulation, estimate the potential impact of the innovations on the defined indicators. This can be done by comparing the projected outcomes with the baseline data.

6. Sensitivity analysis: Conduct sensitivity analysis to assess the robustness of the results and explore different scenarios or assumptions.

7. Interpret and communicate results: Analyze the findings and communicate the potential impact of the innovations on improving access to maternal health. This can help inform decision-making and resource allocation for implementing the recommended interventions.

It is important to note that the methodology for simulating the impact may vary depending on the specific context and available data. It is recommended to involve relevant stakeholders, such as healthcare professionals and policymakers, in the process to ensure the methodology is appropriate and the results are actionable.
