Background: Untreated syphilis in pregnancy is associated with adverse clinical outcomes to the infant. The study aimed to estimate the public health burden resulting from adverse pregnancy outcomes due to syphilis infection among pregnant women not screened for syphilis in 43 countries in sub-Saharan Africa. Methods: Estimated country-specific incidence of syphilis was generated from annual number of live births, the proportion of women with at least 1 antenatal care (ANC) visit, the syphilis prevalence rate, and the proportion of women screened for syphilis during ANC. Adverse pregnancy outcome data (stillbirth, neonatal death, low birth weight, and congenital syphilis) were obtained from published sources. Disabilityadjusted life-year (DALY) estimateswere calculated using undiscounted local life expectancy, the neonatal standard loss function, and relevant disability weights. The model assessed the potential impact of raising ANC coverage to at least 95% and syphilis screening to at least 95% (World Health Organization targets). Results: For all 43 sub-Saharan Africa countries, the estimated incidence of adverse pregnancy outcomes was 205,901 (95% confidence interval [CI], 113,256-383,051) per year, including stillbirth (88,376 [95% CI, 60,854-121,713]), neonatal death (34,959 [95% CI, 23,330-50,076]), low birth weight (22,483 [95% CI, 0-98,847]), and congenital syphilis (60,084 [95% CI, 29,073-112,414]), resulting in approximately 12.5 million DALYs. Countries with the greatest burden are (in DALYs, millions) Democratic Republic of the Congo (1.809), Nigeria (1.598), Ethiopia (1.466), and Tanzania (0.961). Attaining World Health Organization targets could reduce the burden by 8.5 million DALYs. Conclusions: Substantial infant mortality and morbidity results from maternal syphilis infection concentrated in countries with low access to ANC or low rates of syphilis screening.

Innovation recommendations to improve access to maternal health based on the study findings:

1. Strengthen Antenatal Care (ANC) Coverage: Increase efforts to ensure that at least 95% of pregnant women have access to ANC services. This can be achieved by improving healthcare infrastructure, increasing the number of skilled healthcare providers, and implementing community-based ANC programs.

2. Enhance Syphilis Screening: Increase the proportion of pregnant women screened for syphilis during ANC visits to at least 95%. This can be achieved by training healthcare providers on syphilis screening and treatment, improving the availability of testing kits, and implementing routine syphilis screening protocols.

3. Improve Health Education: Implement comprehensive health education programs to raise awareness about the importance of ANC and syphilis screening during pregnancy. This can include community outreach programs, educational campaigns, and targeted messaging to pregnant women and their families.

4. Strengthen Healthcare Systems: Invest in strengthening healthcare systems in sub-Saharan Africa countries, particularly in areas with high burden and low access to ANC. This can involve improving healthcare infrastructure, increasing the availability of essential medicines and supplies, and ensuring an adequate number of skilled healthcare providers.

5. Collaborative Efforts: Foster collaboration between governments, international organizations, non-governmental organizations, and other stakeholders to address the public health burden associated with adverse pregnancy outcomes due to syphilis infection. This can involve sharing best practices, coordinating efforts, and mobilizing resources to support maternal health initiatives.

Implementing these innovations can help reduce the burden of adverse pregnancy outcomes resulting from syphilis infection and improve access to maternal health in sub-Saharan Africa.
AI Innovations Description
Based on the description provided, the recommendation to improve access to maternal health and address the burden of adverse pregnancy outcomes resulting from syphilis infection in sub-Saharan Africa is as follows:

1. Strengthen Antenatal Care (ANC) Coverage: Increase the proportion of pregnant women receiving at least one ANC visit to at least 95%. This can be achieved by implementing strategies such as community-based ANC services, mobile clinics, and outreach programs to reach remote and underserved areas.

2. Enhance Syphilis Screening: Increase the proportion of pregnant women screened for syphilis during ANC to at least 95%. This can be accomplished by training healthcare providers on syphilis testing and treatment, ensuring the availability of rapid diagnostic tests, and integrating syphilis screening into routine ANC services.

3. Improve Health System Infrastructure: Invest in healthcare infrastructure, including facilities, equipment, and supplies, to support the delivery of quality ANC services and syphilis screening. This may involve upgrading existing healthcare facilities, establishing new clinics in underserved areas, and ensuring a reliable supply chain for essential medicines and diagnostic tools.

AI Innovations Methodology
To improve access to maternal health and address the burden of adverse pregnancy outcomes resulting from syphilis infection, the following innovations and recommendations can be considered:

1. Strengthening Antenatal Care (ANC) Services: Enhance ANC services by increasing the number of visits, improving the quality of care, and ensuring comprehensive screening for syphilis and other infections. This can be achieved by training healthcare providers, implementing standardized protocols, and promoting community awareness about the importance of ANC.

2. Integrated Testing and Treatment: Implement integrated testing and treatment programs that combine screening for syphilis with other routine antenatal tests, such as HIV and malaria. This approach can streamline the process, reduce costs, and improve overall access to maternal health services.

3. Mobile Health (mHealth) Solutions: Utilize mobile technologies to enhance access to maternal health services. This can include sending reminders for ANC visits, providing educational information about syphilis prevention, and facilitating teleconsultations for remote areas with limited healthcare facilities.

4. Community-Based Interventions: Engage community health workers and local organizations to raise awareness about syphilis prevention, promote ANC attendance, and encourage early detection and treatment. This can involve conducting community outreach programs, organizing health education sessions, and providing support for pregnant women in accessing healthcare services.

To simulate the impact of these recommendations on improving access to maternal health, a methodology can be developed as follows:

1. Data Collection: Gather data on the current status of ANC coverage, syphilis prevalence, and adverse pregnancy outcomes related to syphilis infection in the target countries or regions. This can be obtained from national health surveys, published studies, and relevant health databases.

2. Model Development: Develop a mathematical model that incorporates the collected data and simulates the impact of the recommendations. The model should consider variables such as ANC coverage, syphilis screening rates, and the effectiveness of interventions in reducing adverse pregnancy outcomes.

3. Parameter Estimation: Estimate the parameters required for the model, such as the probability of adverse outcomes in the absence of interventions, the effectiveness of ANC services, and the impact of the recommended innovations. This can be done through literature review, expert consultation, and statistical analysis of available data.

4. Simulation and Analysis: Run simulations using the developed model to estimate the potential impact of the recommendations on improving access to maternal health and reducing adverse pregnancy outcomes. Analyze the results to determine the projected reduction in disability-adjusted life-years (DALYs) and identify countries or regions that would benefit the most from implementing the recommendations.

5. Sensitivity Analysis: Conduct sensitivity analysis to assess the robustness of the model and evaluate the impact of uncertainties in the input parameters. This can help identify key factors that influence the outcomes and guide decision-making regarding resource allocation and prioritization of interventions.

By following this methodology, policymakers and healthcare stakeholders can gain insights into the potential benefits of implementing the recommended innovations and make informed decisions to improve access to maternal health and reduce the burden of adverse pregnancy outcomes resulting from syphilis infection.
