Comparison of two strategies for administering nevirapine to prevent perinatal HIV transmission in high-prevalence, resource-poor settings

The study aimed to compare two strategies for administering nevirapine (NVP) to prevent perinatal HIV transmission in high-prevalence, resource-poor settings. The two strategies were universal therapy (provision of NVP without HIV testing) and targeted therapy (provision of NVP to seropositive patients identified through voluntary HIV counseling and testing [VCT]). The authors wanted to determine which strategy would result in higher uptake and better adherence, ultimately leading to more effective perinatal HIV prevention.
– Uptake: 67% of pregnant women offered participation accepted. Of those offered enrollment in the universal strategy, 71% accepted, while 64% accepted enrollment in the targeted strategy.
– Uptake Comparison: Uptake was similar at both clinics for the universal strategy, but differed significantly between clinics for the targeted strategy.
– Factors Affecting Uptake: Increased uptake correlated with being offered the universal strategy, attending clinic A, and maternal report of a prior fetal or infant death.
– Adherence: In the universal strategy, 39% of women were nonadherent compared to 26% in the targeted strategy.
– Factors Affecting Adherence: Nonadherence correlated with participation in the universal strategy and illiteracy.
1. Combination Approach: Programs should consider a combination approach where women who desire HIV testing can access NVP through a targeted strategy, and women who do not desire testing can access NVP through a universal strategy. This approach can help save the greatest possible number of infants from perinatal HIV acquisition.
2. Improving VCT Services: Clinics with less well-functioning VCT services may benefit from implementing the universal strategy, as it resulted in better uptake compared to the targeted strategy. Policy makers should focus on improving VCT services to ensure effective implementation of targeted therapy.
1. Healthcare Providers: Responsible for offering and administering NVP therapy, conducting VCT, and providing counseling.
2. Clinic Staff: Involved in the coordination and management of the clinics, ensuring proper implementation of the strategies.
3. Policy Makers: Responsible for developing and implementing policies related to perinatal HIV prevention, including the provision of NVP therapy.
4. Community Health Workers: Play a crucial role in educating and mobilizing pregnant women about the importance of HIV testing and NVP therapy.
1. Training and Capacity Building: Budget for training healthcare providers and clinic staff on the implementation of both the universal and targeted strategies, including counseling and VCT services.
2. Infrastructure and Equipment: Allocate funds for improving clinic infrastructure, including VCT facilities, equipment for NVP administration, and storage of NVP tablets.
3. Supplies and Medications: Budget for the procurement and supply of NVP tablets, HIV testing kits, and other necessary medications and supplies.
4. Community Outreach and Education: Allocate funds for community health workers to conduct outreach activities, educate pregnant women about HIV testing and NVP therapy, and promote the combination approach.
5. Monitoring and Evaluation: Set aside funds for monitoring and evaluating the implementation and effectiveness of the strategies, including data collection and analysis.
Note: The actual cost will depend on the specific context and resources available in each setting.
