The recommendation to improve access to maternal health is to develop and implement a risk score system to identify HIV-infected women who are at high risk of becoming lost to follow-up in the postpartum period. This recommendation is based on a study conducted in Lusaka, Zambia, which found that 25% of pregnant women who initiated combination antiretroviral therapy (cART) were lost to follow-up by 6 months postpartum.
The risk score system would use demographic, obstetric, and HIV-related factors to assess the likelihood of a woman being lost to follow-up. These factors include parity, education, employment status, WHO clinical stage, duration of cART during pregnancy, and number of antenatal care visits. By assigning scores to each factor and calculating a total risk score, healthcare providers can identify women who are at high risk of being lost to follow-up.
The study found that a risk score cut-point of 11 (42nd percentile) had 85% sensitivity and 22% specificity to detect women who were lost to follow-up. This means that the risk score system could accurately identify 85% of women who would become lost to follow-up, but it would also include a significant number of women who would not be lost to follow-up. On the other hand, a risk score cut-point of 18 (69th percentile) identified the 23% of women with the highest probability of being lost to follow-up and had 32% sensitivity and 80% specificity. This means that this cut-point could accurately identify 32% of women who would become lost to follow-up and exclude 80% of women who would not be lost to follow-up.
Implementing a risk score system could help healthcare providers target retention interventions to the subset of women who are most likely to be lost to follow-up. By identifying these women early on, appropriate interventions can be put in place to ensure their continued access to HIV care and treatment. This innovation has the potential to improve maternal HIV outcomes by enhancing retention in HIV care during the postpartum period.
The recommendation and findings of this study were published in the journal AIDS Care – Psychological and Socio-Medical Aspects of AIDS/HIV in 2016.

AI Innovations Methodology
To simulate the impact of the main recommendations of this abstract on improving access to maternal health, you can follow these steps:
1. Identify the target population: Determine the specific population of HIV-infected pregnant women who would benefit from the risk score system. This could include women receiving antenatal care and initiating cART in a specific region or healthcare facility.
2. Collect data: Gather data on the demographic, obstetric, and HIV-related factors mentioned in the abstract, such as parity, education, employment status, WHO clinical stage, duration of cART during pregnancy, and number of antenatal care visits. This data can be obtained through medical records or surveys.
3. Develop the risk score system: Use logistic regression or another appropriate statistical method to analyze the collected data and develop a risk score system. Assign scores to each factor based on their association with loss to follow-up (LTFU) and calculate a total risk score for each woman.
4. Determine risk score cut-points: Determine the appropriate risk score cut-points based on the sensitivity and specificity values mentioned in the abstract. These cut-points will help identify women at high risk of being lost to follow-up.
5. Apply the risk score system: Apply the risk score system to the target population by calculating the risk scores for each woman. Identify women who meet the risk score cut-points and are at high risk of LTFU.
6. Implement targeted retention interventions: Develop and implement targeted retention interventions for the subset of women identified as being at high risk of LTFU. These interventions could include personalized counseling, reminder systems, peer support, or community outreach programs.
7. Monitor and evaluate outcomes: Continuously monitor and evaluate the impact of the risk score system and targeted interventions on improving access to maternal health. Track the number of women who remain engaged in HIV care during the postpartum period and assess any changes in LTFU rates.
8. Adjust and refine the system: Based on the outcomes and feedback from healthcare providers and patients, make any necessary adjustments or refinements to the risk score system and targeted interventions to further improve access to maternal health.
By following this methodology, you can simulate the impact of the risk score system on improving access to maternal health for HIV-infected women in the postpartum period.
