South Africa’s initiatives to provide daily oral pre-exposure prophylaxis (PrEP) for HIV prevention reveal significant differences in both costs and effectiveness across various communities. A recent study examined how different delivery models impact the accessibility and sustainability of PrEP programs among key populations, including men who have sex with men, female sex workers, and young women.
Diverse Delivery Models Assessed
Researchers conducted a retrospective analysis across seven urban sites, evaluating both in-facility and community outreach programs. The study encompassed participants aged 15 and above who began PrEP between March 2018 and August 2019. By employing top-down and bottom-up microcosting methods, the team assessed the financial aspects from the provider’s perspective, focusing on the cost per client initiating PrEP and the sustainability of PrEP usage over time.
Variable Outcomes Highlight Challenges
The findings revealed a broad range in the proportion of participants maintaining PrEP access at the six-month mark, from as low as 0% in certain outreach settings to over 41% in specific clinics catering to men who have sex with men. Additionally, only a small fraction of participants continued PrEP use after a year, indicating potential issues with long-term adherence and program retention.
• In-facility programs generally incur higher costs compared to outreach initiatives.
• Cost per client varied dramatically, emphasizing the need for tailored financial strategies.
• Low long-term retention rates suggest barriers to sustained PrEP usage.
The economic analysis showed that initiating PrEP costs ranged from $29 to $590 per client, with monthly costs for maintaining PrEP access between $18 and $160. These variations underline the financial challenges in scaling up PrEP programs effectively across different settings and populations.
Optimizing PrEP delivery requires a nuanced understanding of local contexts to enhance both cost-efficiency and program effectiveness. Policymakers must consider these disparities to allocate resources strategically, ensuring that high-impact populations receive adequate support. Addressing the underlying factors that influence PrEP adherence and retention will be crucial in achieving long-term HIV prevention goals.
Future strategies should focus on integrating PrEP services with other health interventions to provide comprehensive support, thereby improving adherence rates. Additionally, leveraging community-based approaches may offer more sustainable and cost-effective solutions compared to traditional in-facility models. Continuous monitoring and adaptive management will be essential to respond to the evolving needs of diverse populations effectively.
Enhancing the scalability of PrEP programs in South Africa hinges on balancing financial constraints with the urgent need to prevent HIV transmission. By tailoring approaches to specific community needs and improving retention strategies, the country can make significant strides in combating the HIV epidemic.
