Background: Early access to diagnosis and care is essential to improve rates of survival from childhood cancer, particularly in low-income and middle-income countries (LMICs). Composite indices are increasingly used to compare country performance in many health fields. We aimed to develop a composite vulnerability index of risk of mortality associated with delays in care for childhood cancer in LMICs, and to compare the vulnerability index scores across countries. Methods: The composite vulnerability index was built in ten steps. A previous systematic review of determinants of delays in cancer care for children guided data selection. We collected exposure variables (determinants of delays in care) and outcome variables (childhood cancer-related mortality) from several large datasets. Data were analysed with regression models to identify determinants of delays in care that contribute to childhood cancer mortality. Significant indicators were aggregated into domains according to the socio-ecological model. We used geospatial tools to summarise and compare the composite vulnerability index scores across countries. Findings: We found that life expectancy, maternal education, fertility rate, availability of pathology services, bone marrow transplantation capacity, availability of treatment services (chemotherapy, radiotherapy, or surgery), number of pharmacists per 10 000 population, country income level, and out-of-pocket health expenditure were significantly associated with cancer mortality for children in LMICs. The highest levels of vulnerability were found in sub-Saharan Africa. Interpretation: Our composite vulnerability index can potentially serve as a valuable policy decision tool to help monitor country performance and guide interventions to reduce delays in care for children with cancer in LMICs.

Based on the provided description, here are some potential innovations that could improve access to maternal health:

1. Telemedicine: Implementing telemedicine services can help overcome geographical barriers and provide remote access to healthcare professionals for prenatal care, consultations, and monitoring.

2. Mobile health (mHealth) applications: Developing user-friendly mobile applications that provide information, reminders, and educational resources for pregnant women can enhance access to maternal health services and promote self-care.

3. Community health workers: Training and deploying community health workers who can provide essential maternal health services, including prenatal care, health education, and referrals, especially in remote or underserved areas.

4. Maternal health clinics: Establishing dedicated maternal health clinics that offer comprehensive services, including prenatal care, antenatal screenings, vaccinations, and postnatal care, to ensure accessible and specialized care for pregnant women.

5. Transportation solutions: Implementing innovative transportation solutions, such as mobile clinics or ambulances, to facilitate the transportation of pregnant women to healthcare facilities, particularly in rural or hard-to-reach areas.

6. Financial incentives: Introducing financial incentives, such as conditional cash transfers or subsidies, to encourage pregnant women to seek timely and regular maternal health services, including prenatal check-ups and skilled birth attendance.

7. Health information systems: Developing robust health information systems that enable efficient data collection, analysis, and monitoring of maternal health indicators, facilitating evidence-based decision-making and targeted interventions.

8. Public-private partnerships: Collaborating with private sector entities, such as pharmaceutical companies or technology providers, to leverage their resources, expertise, and networks to improve access to maternal health services and technologies.

9. Maternal health education programs: Implementing comprehensive maternal health education programs in schools, communities, and healthcare facilities to raise awareness, promote healthy behaviors, and empower women to make informed decisions regarding their maternal health.

10. Quality improvement initiatives: Implementing quality improvement initiatives in healthcare facilities to enhance the overall quality of maternal health services, including training healthcare providers, improving infrastructure, and ensuring the availability of essential supplies and equipment.
AI Innovations Description
The recommendation to improve access to maternal health based on the described study is to develop a similar composite vulnerability index specifically focused on maternal health in low-income and middle-income countries (LMICs). This index would identify determinants of delays in accessing maternal health care and assess the risk of maternal mortality associated with these delays. The index would be built using a similar methodology as described in the study, including data collection from various sources and analysis using regression models.

The determinants of delays in accessing maternal health care could include factors such as availability of healthcare facilities, skilled birth attendants, prenatal and postnatal care services, transportation infrastructure, education level of women, and healthcare expenditure. These determinants would be aggregated into domains based on the socio-ecological model.

By developing and using this composite vulnerability index, policymakers and healthcare providers can monitor country performance in addressing delays in accessing maternal health care and guide interventions to reduce these delays. This index can serve as a valuable tool to prioritize resources, target interventions, and improve access to maternal health services in LMICs, ultimately reducing maternal mortality rates.

To improve access to maternal health, the following innovations could be considered:

1. Telemedicine: Implementing telemedicine solutions can help overcome geographical barriers and improve access to maternal health services. This technology allows healthcare providers to remotely monitor and provide consultations to pregnant women, reducing the need for travel and increasing access to healthcare expertise.

2. Mobile health (mHealth) applications: Developing mobile applications that provide maternal health information, reminders for prenatal care appointments, and access to teleconsultations can empower pregnant women to take control of their health and access necessary care conveniently.

3. Community health workers: Training and deploying community health workers who can provide basic maternal health services, education, and referrals in remote or underserved areas can improve access to care for pregnant women who may face transportation or financial barriers.

4. Maternal health clinics: Establishing dedicated maternal health clinics in underserved areas can ensure that pregnant women have access to comprehensive prenatal care, including regular check-ups, screenings, and counseling services.

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

1. Data collection: Gather data on the current state of maternal health access, including indicators such as distance to healthcare facilities, availability of healthcare providers, and utilization rates of maternal health services.

2. Define simulation parameters: Determine the specific variables and metrics that will be used to measure the impact of the recommendations. For example, the number of telemedicine consultations conducted, the increase in the number of community health workers, or the establishment of maternal health clinics.

3. Model development: Develop a simulation model that incorporates the collected data and simulates the implementation of the recommendations. This model should consider factors such as population demographics, healthcare infrastructure, and resource availability.

4. Scenario testing: Run simulations using different scenarios to assess the potential impact of each recommendation on improving access to maternal health. This could involve adjusting variables such as the number of telemedicine consultations or the distribution of community health workers.

5. Analyze results: Evaluate the simulation results to determine the potential impact of each recommendation on improving access to maternal health. This analysis can help identify the most effective strategies and prioritize their implementation.

6. Refine and iterate: Based on the simulation results, refine the recommendations and simulation model as necessary. Repeat the simulation process to further optimize the strategies for improving access to maternal health.

By following this methodology, policymakers and healthcare stakeholders can gain insights into the potential impact of different innovations on improving access to maternal health and make informed decisions on their implementation.
