Background: Malaria during pregnancy remains a major public health problem. A consortium from Africa and Europe is further advancing the clinical development of two PM vaccine candidates (PAMVAC-cVLP and PRIMVAC). These vaccines have previously been shown to be safe, well-tolerated and able to induce a strong and functional immune response. Monitoring pregnancy outcomes during pregnancy is very important in assessing the effectiveness of interventions against PM. The increased availability of mobile phones makes them a potential tool for improving quality of care for pregnant women, accurately collecting and reporting pregnancy outcomes in identified cohorts of pregnant women. Data on the feasibility and acceptability of the mobile applications for tracking pregnancy outcomes in the areas targeted for clinical testing of candidate PM vaccines is however limited. This study will explore the creation of electronic pregnancy registers and evaluate pregnancy mobile applications as a potential tool for monitoring pregnancy outcomes in future PM vaccine trials, as well as for the implementation of other future interventions in Ghana, Burkina Faso, Benin and Malawi.

Overall aim: To evaluate the feasibility and acceptability of open-source mobile applications in tracking pregnancy outcomes among pregnant women in sub- Saharan Africa.

Methods: The study will be carried out in two phases. The first phase will involve the mapping of health application tools, and the selection of one of the tools for the registration of pregnancies at each of the participating sites. The evaluation process will involve a two-level test namely alpha and beta. Prior to the selection of the electronic tool, the team will define the data characteristics and requirements of the pregnancy register. This will be followed by a description of the process flow and the expected functionality of the pregnancy register including visualization and reporting of outcomes of interest. After this, specifications of the interface technologies, the database technologies, and the network requirements will be determined. Each site will create a pregnancy register using REDCap. The second phase will involve the assessment of the feasibility and acceptability of mobile application. At the evaluation phase, qualitative methods will be used to assess the feasibility and acceptability of using the selected mobile application for tracking pregnancy outcomes. The selected app will be tested by pregnant women. In-depth interviews (IDIs) and focus group discussions (FGDs) will be used to explore the perceptions of pregnant women and health workers on the feasibility, usability, and acceptability of open-source mobile applications for tracking pregnancy outcomes among pregnant women. Pregnant women from rural and urban parts of the study areas who will be able to use the electronic application and are willing to participate in the interviews will be purposively selected from the pregnancy register, and health workers sampled from the health facilities.

Expected outcome: The assessment of mobile applications for monitoring pregnancy outcomes and development of pregnancy registers will build the base for future PM vaccine trials and any other interventions tackling PM. If acceptability and feasibility is demonstrated, mobile applications could be linked to other tools that will provide support to front line health care workers and patients to ensure uptake and continued access to essential maternal and neonatal care services through responsive customized needs of patients in view of routine care packages.
