BACKGROUND: Undiagnosed human immunodeficiency virus (HIV) infection remains a public health challenge. We explore Facebook (FB) advertisement (Ads) cost per new HIV diagnosis using non-targeted Ads, a routine testing model against targeted Ads, and a focused testing model in Texas. METHODS: On 14 October 2021, we created (without launching) Texas-based, USD 10 targeted (using criteria matching HIV populations at risk) and non-targeted FB Ads for 10 days. In the process of creating the Ads, we collected estimated audience size, daily reach, and daily clicks. We estimated Ad cost for each new HIV diagnosis for targeted and non-targeted Ads using new HIV diagnosis rates from focused and routine testing campaigns. RESULTS: The Ad costs per new HIV diagnosis from the targeted model were 4.74, 2.86, 5.28, and 2.88 times lower for men, Black, Hispanic, and all age groups, respectively, when compared to the non-targeted model. The wider the gap was between new HIV diagnosis rates in a population for focused and routine testing, the more cost-effective targeted Ads became. CONCLUSIONS: Among HIV populations at risk, targeted FB Ads are more cost-effective for detecting new HIV infections than non-targeted Ads. This cost-effectiveness increases in locations where focused testing increases new HIV diagnosis rates, compared to routine testing.
背景:未确诊的人类免疫缺陷病毒(HIV)感染仍然是一项公共卫生挑战。我们在德克萨斯州探索使用非定向广告、针对定向广告的常规检测模型以及重点检测模型来计算每例新HIV诊断的脸书(FB)广告成本。 方法:2021年10月14日,我们创建了(未投放)以德克萨斯州为基础、10美元的定向(使用与HIV高危人群匹配的标准)和非定向FB广告,为期10天。在创建广告的过程中,我们收集了估计的受众规模、每日覆盖范围和每日点击量。我们使用重点检测和常规检测活动中的新HIV诊断率来估算定向和非定向广告每例新HIV诊断的广告成本。 结果:与非定向模型相比,定向模型每例新HIV诊断的广告成本在男性、黑人、西班牙裔和所有年龄组中分别低4.74倍、2.86倍、5.28倍和2.88倍。重点检测和常规检测人群中新HIV诊断率的差距越大,定向广告就越具成本效益。 结论:在HIV高危人群中,与非定向广告相比,定向FB广告在检测新HIV感染方面更具成本效益。与常规检测相比,在重点检测提高新HIV诊断率的地区,这种成本效益会增加。
