The evidence in the abstract is strong, with a rating of 9. The study is a population-based cohort study using data from three demographic surveillance sites in Eastern and Southern Africa. Verbal autopsy data was used, and cause of death was assigned using the InSilicoVA algorithm. The study reports direct maternal mortality rates by HIV status, and crude and adjusted rate ratios comparing HIV-infected and uninfected women. The study also conducted a meta-analysis to pool the rate ratios across the study sites. The results show a consistent increase in the rate of direct maternal mortality among HIV-infected women across all study sites. The study provides specific rate ratios and confidence intervals to support the findings. The conclusion suggests the need to improve access to quality maternity care for HIV-infected women. To improve the evidence, the study could consider including a larger sample size and conducting a longer follow-up period to strengthen the generalizability of the findings.

OBJECTIVE: To assess whether HIV is associated with an increased risk of mortality from direct maternal complications. DESIGN: Population-based cohort study using data from three demographic surveillance sites in Eastern and Southern Africa. METHODS: We use verbal autopsy data, with cause of death assigned using the InSilicoVA algorithm, to describe the association between HIV and direct maternal deaths amongst women aged 20-49 years. We report direct maternal mortality rates by HIV status, and crude and adjusted rate ratios comparing HIV-infected and uninfected women, by study site and by ART availability. We pool the study-specific rate ratios using random-effects meta-analysis. RESULTS: There was strong evidence that HIV increased the rate of direct maternal mortality across all the study sites in the period ART was widely available, with the rate ratios varying from 4.5 in Karonga, Malawi [95% confidence interval (CI) 1.6-12.6] to 5.2 in Kisesa, Tanzania (95% CI 1.7-16.1) and 5.9 in uMkhanyakude, South Africa (95% CI 2.3-15.2) after adjusting for sociodemographic confounders. Combining these adjusted results across the study sites, we estimated that HIV-infected women have 5.2 times the rate of direct maternal mortality compared with HIV-uninfected women (95% CI 2.9-9.5). CONCLUSION: HIV-infected women face higher rates of mortality from direct maternal causes, which suggests that we need to improve access to quality maternity care for these women. These findings also have implications for the surveillance of HIV/AIDS-related mortality, as not all excess mortality attributable to HIV will be explicitly attributed to HIV/AIDS on the basis of a verbal autopsy interview.

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

1. Integrated HIV and maternal health services: Implementing integrated healthcare services that combine HIV prevention, treatment, and care with maternal health services can improve access for HIV-infected women. This approach ensures that women receive comprehensive care and support during pregnancy, childbirth, and postpartum.

2. Task-shifting and training: Training and empowering non-specialist healthcare providers, such as nurses and midwives, to deliver quality maternal health services can help address the shortage of skilled healthcare professionals. Task-shifting can increase access to essential maternal health services, including HIV testing, antenatal care, and skilled birth attendance.

3. Mobile health (mHealth) interventions: Utilizing mobile technology to deliver maternal health information, reminders, and appointment notifications can help overcome barriers to accessing healthcare. Mobile health interventions can also provide HIV-infected women with access to virtual consultations, telemedicine services, and support networks.

4. Community-based interventions: Engaging communities and community health workers in maternal health promotion and education can improve access to care. Community-based interventions can include awareness campaigns, home visits, and support groups to ensure that HIV-infected women receive the necessary care and support throughout their pregnancy and beyond.

5. Strengthening health systems: Investing in health system strengthening, including infrastructure development, procurement of essential medical supplies, and improving referral systems, can enhance access to quality maternal health services. This includes ensuring the availability of antiretroviral therapy (ART) for HIV-infected pregnant women to prevent mother-to-child transmission of HIV.

It is important to note that these recommendations are general and may need to be tailored to specific contexts and resource constraints.
