预测 HIV 暴露前预防 (PrEP) 的影响和成本效益的模型必须具体说明 PrEP 的使用如何与 HIV 暴露保持一致。我们假设,根据个人层面的伙伴关系动态来改变 PrEP 的使用,而不是根据平均风险对人群亚组进行优先排序,将导致更大的发病率降低和更高的效率。我们使用基于斯威士兰 HIV 动态的基于个体的网络传播模型来模拟 2022 年至 2031 年间 15-34 岁个体在 PrEP 交付的两种模式下的 PrEP 使用情况:“风险组”和“伙伴关系”。在“风险组”范式中,我们根据平均合作频率和并发性定义的风险组(低、中和高)改变了 PrEP 覆盖范围。在“伙伴关系”范式中,所有个人都有可能符合 PrEP 资格,但我们假设仅在伙伴关系期间使用,并且根据伙伴 HIV 状况确定不同的优先级(对于 HIV 阳性伙伴,没有优先级到高优先级)。我们计算了相对于无 PrEP 情况的 PrEP 人次和发病率,并估计了避免一种额外感染所需的 PrEP 人年数 (NNT) 的效率。在风险组范式中,将 PrEP 限制在高风险组是最有效的(NNT = 17),但避免的感染数量受到高风险组规模较小的限制。将 PrEP 的使用范围扩大到所有风险人群可避免的感染数量增加三倍,但效率较低 (NNT = 202)。合作伙伴范式下的 PrEP 使用效率比风险组范式高 2-6 倍(NNT = 33-102),所有组均符合 PrEP 资格。在风险组范式中,PrEP 覆盖率为 46%(95% CI:39-52%),在伙伴范式中,15 至 34 岁人群的发病率降低了 33%,为 6%(95% CI:5-7%)至 17%(95% CI:14-20%)。基于风险群体的 PrEP 使用建模导致 PrEP 效率和影响之间的尖锐权衡,而基于伙伴关系的 PrEP 使用则导致广泛 PrEP 可用性的效率更高。 PrEP 在普遍流行病中的影响和成本效益的模型估计受到关于 PrEP 使用如何与个体水平的 HIV 暴露异质性相一致的假设的强烈影响。
Models that project the impact and cost‐effectiveness of HIV pre‐exposure prophylaxis (PrEP) must specify how PrEP use aligns with HIV exposure. We hypothesized that varying PrEP use according to individual‐level partnership dynamics rather than prioritization to population subgroups based on average risk will result in larger incidence reductions and greater efficiency. We used an individual‐based network transmission model calibrated to HIV dynamics in Eswatini to simulate PrEP use among individuals ages 15–34 between 2022 and 2031 under two paradigms of PrEP delivery: “Risk Group” and “Partnership.” In the “Risk Group” paradigm, we varied PrEP coverage by risk groups (low, medium and high) defined by average partnership frequency and concurrency. In the “Partnership” paradigm, all individuals are potentially eligible for PrEP, but we assumed use occurs only during partnerships and varied prioritization by partner HIV status (no prioritization to high prioritization with HIV‐positive partners). We calculated person‐time on PrEP and incidence relative to a no PrEP scenario and estimated efficiency as the person‐years of PrEP needed to avert one additional infection (NNT). In the Risk Group paradigm, restricting PrEP to the high‐risk group was the most efficient (NNT = 17), but the number of infections averted was limited by the small size of the high‐risk group. Expanding PrEP use to all risk groups averted up to three times more infections but with lower efficiency (NNT = 202). PrEP use under the Partnership paradigm was 2–6 times more efficient (NNT = 33–102) than the Risk Group paradigm with all groups eligible for PrEP. A 33% reduction in incidence among 15‐ to 34‐year‐olds was achieved at 46% (95% CI: 39–52%) PrEP coverage in the Risk Group paradigm and 6% (95% CI: 5–7%) to 17% (95% CI: 14–20%) in the Partnership paradigm. Modelling PrEP use based on risk groups resulted in a sharp trade‐off between PrEP efficiency and impact, whereas PrEP use predicated on partnerships resulted in much higher efficiency for widespread PrEP availability. Model estimates of PrEP impact and cost‐effectiveness in generalized epidemics are strongly influenced by assumptions about how PrEP use aligns with individual‐level HIV exposure heterogeneity.
