Maternal, Neonatal and Infant Outcomes at Kawempe National Referral Hospital (PREPARE)
Prevention of Invasive Group B Streptococcus Disease in Young Infants: a Pathway for the Evaluation & Licensure of an Investigational Maternal GBS Vaccine (Work Package 2)
Maternal immunisation is an evolving field that deserves special attention given its potential to have a significant positive impact on the health of women and children globally, and the potential safety and risk considerations associated with research in this population.
The goal of maternal immunisation is to boost maternal levels of specific antibodies to provide the newborn and young infant with sufficient immunity at birth, through trans placental transfer in-utero, to protect them through the period of increased vulnerability. Protection should be adequate to last until they are able to respond to their own active immunisations or infectious challenges. The success of the maternal neonatal tetanus immunisation program demonstrates the utility of this approach. Several other vaccines are recommended in pregnancy, including influenza and pneumococcal vaccines. Promising new vaccines for group B streptococcus (GBS) , respiratory syncytial virus (RSV) and cytomegalovirus are under development. They are targeted for use in pregnant women in high-, middle-, and low-income countries. However, these vaccines are likely to be of most benefit in LMICs that have high rates of vaccine preventable diseases.
The second work-package (WP2) of the PREPARE portfolio will describe the baseline maternal and neonatal outcomes using anonymised data collected using the routine Kawempe electronic medical records (EMR) system.
Furthermore, comprehensive data on pregnancy, neonatal and infant outcome will also be collected in a prospective cohort of women enrolled in the first and second trimesters while attending antenatal care at Kawempe Hospital with follow-up of the mother-infant pair(s) up until at least 14 weeks postpartum to establish longer term outcomes. Standardised case definitions will be used to classify the outcomes.

Detailed Description
Maternal Immunisation research in LMICs
Maternal immunisation is an evolving field that deserves special attention given its potential to have a significant positive impact on the health of women and children globally, and the potential safety and risk considerations associated with research in this population.
Prior to undertaking any maternal vaccine study, it is vital that the background rates of pregnancy and neonatal outcomes are clearly documented as these vary by setting, so that safety signals during vaccine trials can be correctly assessed . Given the important contribution that maternal immunisations could make to reducing maternal and neonatal morbidity, efforts are underway to standardise case definitions used to classify adverse events in maternal vaccine trials. Historically, this has not been the case, limiting comparability between countries and pre and post-licensure. In 2014, in response to a call from the World Health Organisation (WHO) and with funding from the Bill & Melinda Gates Foundation, the GAIA (Global Alignment on Immunisation Safety Assessment in pregnancy) consortium was formed, with the goal of developing a harmonised, globally concerted approach to actively monitor the safety of clinical trials, vaccines and immunization programs in pregnancy. The group have developed 21 standardised case definitions for the classification of adverse obstetric and neonatal events including the need to follow up vaccinated women for 6 months and infants for one year following vaccination.
Study Setting Uganda has a long history of conducting prevention of mother to child HIV transmission (PMTCT) trials as well as vaccine trials for Ebola and Human Immunodeficiency Virus 9. The established National Drug Authority (NDA) and National Immunisation Technical Advisory Group (NITAG) provide pharmacovigilance capacity and an effective platform for monitoring drug and vaccine safety. Makerere University John Hopkins University Research Collaboration (MUJHU) has led multiple PMTCT and HIV therapeutic trials 10. This collaboration with St George's University, who are leaders in immunisation research, presents a unique opportunity to develop a maternal vaccination platform for future trials in Uganda.
Funding has been provided from the European Developing Countries Clinical Trials Partnership (EDCTP) to develop a maternal vaccine trial platform at Kawempe National Referral Hospital. It is anticipated that a tetanus, diptheria and acellular pertussis (Tdap) study will be conducted in 2020 followed by two GBS vaccine trials.
The study site, Kawempe National Referral Hospital, is developing as a centre of excellence for maternal and child health studies in Uganda with several large studies of neonatal encephalopathy, neonatal resuscitation (Clinical Trials - NCT03133572) and birth defects 11 being conducted at the site. Capacity building activities in Kawempe have included implementation and piloting of an electronic medical record (EMR) system to enhance routine data collection. This system provides an opportunity for embedding vaccine surveillance activities for adverse pregnancy outcomes into routine data capture systems which support clinical care.
Kawempe Electronic Medical Record The Uganda Electronic Medical Record (UgandaEMR) is an electronic health record system developed to capture patient level data collected during service delivery. The system is supported by Uganda's Ministry of Health through its Department of Health Informatics (DHI) with technical support from the CDC funded Monitoring and Evaluation Technical support program (METs) under the Makerere University School of Public Health. The system was developed based on open source technology, OpenMRS, and was initially implemented to capture patient level data for HIV care and treatment programs. The system has been rolled out to more than 600 health facilities countrywide and METS aim to rollout it out to 1000 health facilities by the end of 2019. Makerere University John's Hopkins University Research Collaboration (MUJHU) pioneered extension of the system to capture Maternal and Child Health (MCH) information through a pilot implementation initiated in February 2017 in the high-volume national referral hospital in Kawempe, Kampala. Additional data entrants were deployed to capture the e-data in parallel to the standard paper register-based data collection coupled with training and continuous quality improvement measures to support and promote complete and accurate recording in the hospital source forms. An evaluation of the pilot implementation found significant improvement in completeness of both paper and electronic data collected during service delivery from an average of 60% at baseline to over 90% at the end of the pilot implementation period.
GBS Vaccine Research The PREPARE project is an international collaboration that aims to accelerate GBS vaccine development and licensure. It is composed of five work packages (WP). As part of the EDCTP funded PREPARE project two GBS vaccine trials (PREPARE WP4 and 5) will be conducted at Kawempe National Referral Hospital.
In preparation for GBS clinical trials, PREPARE WP2 aims to characterise the Kawempe National Referral hospital baseline pregnancy, neonatal and infant outcomes in preparation for future GBS vaccine trial studies. Pregnancy is associated with complications which must be differentiated from adverse events associated with the administration of vaccines. The frequency of such pregnancy related complications varies significantly by geographical location and the prevalence of such pregnancy and neonatal outcomes are poorly documented in majority of developing countries.
