Purpose The Hlabisa pregnancy cohort was established to evaluate the effectiveness of prevention of mother-to-child transmission (PMTCT) guideline revisions. The objectives of the Hlabisa pregnancy cohort are to: (1) provide cohort-level information on maternal health up to 6 weeks postpartum in a high HIV prevalence setting; and to (2) evaluate aspects of PMTCT care that have policy relevance. Participants The pregnancy cohort is located in primary health clinics in the Hlabisa subdistrict of rural KwaZulu-Natal, South Africa. Baseline data collection between 2010 and 2014 has been completed with the enrolment of 25 608 pregnancies; age ranged from 15-49 years. Pregnant women were assessed during routine antenatal visits: first visit, follow-up 1 week later, 32 weeks (HIV test), infant delivery and 6 weeks postpartum. Demographic, pregnancy, clinical, laboratory and HIV data were collected through Department of Health interviews, laboratory tests and routine data linkage. Treatment data for HIV-infected pregnant women were linked to the Africa Centre Hlabisa HIV Treatment and Care Programme for detailed antiretroviral therapy (ART) history and laboratory tests. Findings to date The proportion of women initiated on ART post-2013 were higher (n=437; 100%) than pre-2013 (n=768; 84.2%). The proportion of women in care at 6 weeks (73.8%) was also higher post-2013 relative to earlier years (58.5%). The majority of HIV-infected pregnant women were either on lifelong ART or ART prophylaxis; pre-2013, ∼ 9.6% of women were not on any ART. Pregnancy viral load monitoring was inadequate. Future plans This cohort will be used to: (1) determine HIV acquisition risk during pregnancy and postpartum; (2) determine the effect of HIV and ART on birth outcomes; (3) examine the effect of pregnancy on virological response to ART; and (4) characterise the effect of sequential pregnancies on access to clinical care, response to prolonged ART and birth outcomes.

N/A

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

1. Mobile health (mHealth) interventions: Develop mobile applications or text messaging services to provide pregnant women with information on antenatal care, PMTCT guidelines, and reminders for clinic visits and medication adherence.

2. Telemedicine: Implement telemedicine services to enable remote consultations between pregnant women and healthcare providers, reducing the need for travel and improving access to specialized care.

3. Community health workers: Train and deploy community health workers to provide education, support, and follow-up care to pregnant women in rural areas, bridging the gap between healthcare facilities and the community.

4. Integrated healthcare services: Establish integrated healthcare facilities that offer comprehensive maternal health services, including antenatal care, HIV testing and treatment, family planning, and postpartum care, to ensure continuity of care and reduce fragmentation.

5. Task-shifting: Train and empower nurses and midwives to perform tasks traditionally done by doctors, such as initiating and managing antiretroviral therapy for pregnant women with HIV, to increase access to essential services.

6. Quality improvement initiatives: Implement quality improvement programs to address gaps in pregnancy viral load monitoring, ensuring that pregnant women receive regular monitoring to assess the effectiveness of their antiretroviral therapy and prevent mother-to-child transmission of HIV.

7. Health information systems: Strengthen health information systems to enable better data collection, analysis, and monitoring of maternal health outcomes, allowing for evidence-based decision-making and targeted interventions.

These innovations have the potential to improve access to maternal health services, enhance the effectiveness of PMTCT care, and ultimately contribute to better maternal and child health outcomes.
AI Innovations Description
Based on the information provided, the recommendation to improve access to maternal health would be to implement a comprehensive and integrated maternal health program that focuses on the following areas:

1. Strengthening Prevention of Mother-to-Child Transmission (PMTCT) Guidelines: Continuously evaluate and update PMTCT guidelines to ensure they are evidence-based and aligned with the latest research and recommendations. This will help improve the effectiveness of PMTCT interventions and reduce the risk of HIV transmission from mother to child.

2. Enhancing Antenatal Care: Improve the quality and coverage of antenatal care services by providing comprehensive assessments and interventions during routine antenatal visits. This includes regular monitoring of maternal health indicators, such as viral load, to ensure timely interventions and appropriate management of HIV-infected pregnant women.

3. Increasing Access to Antiretroviral Therapy (ART): Ensure that all HIV-infected pregnant women have access to ART, either as lifelong therapy or as prophylaxis, based on their individual needs and the latest treatment guidelines. This will help improve maternal health outcomes and reduce the risk of vertical transmission of HIV.

4. Strengthening Postpartum Care: Extend the focus on maternal health beyond delivery by providing comprehensive postpartum care up to 6 weeks postpartum. This includes regular follow-up visits, monitoring of maternal health indicators, and support for adherence to ART and other postpartum interventions.

5. Promoting Continuity of Care: Develop strategies to ensure that women receive continuous and uninterrupted care throughout their reproductive journey, including during subsequent pregnancies. This includes addressing barriers to accessing care, such as transportation, stigma, and financial constraints.

6. Conducting Research and Evaluation: Utilize cohort studies, like the Hlabisa pregnancy cohort, to gather data and evaluate the impact of interventions on maternal health outcomes. This will help identify areas for improvement and guide future policy and programmatic decisions.

By implementing these recommendations, it is expected that access to maternal health services will be improved, leading to better health outcomes for both mothers and their infants.
