Post-exposure Prophylaxis (PEP) is an effective yet underutilized HIV prevention tool. PEPTALK developed and evaluated a media campaign to drive demand for PEP among men who have sex with men (MSM) and transgender women (TW) living in high HIV prevalence areas in New York City. Formative qualitative research (38 in-depth interviews and five focus groups [N = 48]) with Black or African-American MSM or TW who reported condomless sex with a HIV-positive/unknown status man was conducted to inform campaign design. We assessed the impact of the campaign, 15 bus shelter ads and low or no-cost social media, by assessing change in the proportions of new PEP patient visits, to the clinical site where the campaign directed consumers, using one-sided z-test for proportions, before and after the media campaign. The proportion of new PEP patients increased significantly after the media campaign in the periods examined, suggesting that such campaigns may increase PEP demand.

“这就像 B 计划，但针对的是 HIV！” 设计和评估媒体活动以推动 PEP 需求。

暴露后预防 (PEP) 是一种有效但未得到充分利用的艾滋病毒预防工具。PEPTALK 制定并评估了一项媒体宣传活动，以推动居住在纽约市艾滋病毒高发地区的男男性行为者 (MSM) 和变性女性 (TW) 对 PEP 的需求。对报告与 HIV 阳性/身份不明的男性发生无安全套性行为的黑人或非裔美国 MSM 或 TW 进行了形成性定性研究（38 次深度访谈和 5 个焦点小组 [N = 48]），为活动设计提供信息。我们使用单边 z 检验评估了该活动、15 个公交候车亭广告和低成本或免费社交媒体的影响，方法是评估新 PEP 患者到该活动引导消费者的临床站点就诊的比例变化媒体宣传活动之前和之后的比例。在调查期间的媒体宣传活动后，新 PEP 患者的比例显着增加，表明此类宣传活动可能会增加 PEP 需求。
