Human immunodeficiency virus (HIV) partner services are an essential component of comprehensive HIV prevention and care. We examined factors associated with partner notification, HIV testing, and HIV positivity among partners of HIV-diagnosed persons (index persons) contacted by Centers for Disease Control and Prevention (CDC)-funded state and local health departments.
We analyzed partner service data submitted to the CDC by 61 state and local health departments from 2013 to 2017. Using multivariate Poisson regression-adjusted for clustering effects among partners reported by a common index person-we assessed associations between 3 outcomes of interest (partner notification, HIV testing, and HIV positivity) and the demographic characteristics, risk behaviors, geographic region, and service year of index persons and their partners.
A total of 51,368 sexual and/or needle-sharing partners were matched with 33,524 index persons. Of notifiable partners, 97.2% were notified of their potential HIV exposure, and 52.3% were tested for HIV. Among 21,842 notified and tested partners, 23.8% were newly diagnosed with an HIV infection. Partner notification, HIV testing, and HIV positivity were associated with both partner and index person characteristics (individually and interactively), geographic region, and year of service.
Partner service programs provided through CDC-funded health departments were effective in both partner notification and identification of undiagnosed HIV infection among partners. However, HIV testing rate among notified partners remained low. Implementing strategies to address gaps in HIV testing can contribute toward ending the HIV epidemic in the United States.
人类免疫缺陷病毒（HIV）伴侣服务是全面HIV预防与护理的重要组成部分。我们研究了疾病控制与预防中心（CDC）资助的州和地方卫生部门所联系的HIV确诊者（索引病例）的伴侣中，与伴侣通知、HIV检测及HIV阳性相关的因素。
我们分析了2013年至2017年61个州和地方卫生部门提交给CDC的伴侣服务数据。使用多变量泊松回归，并针对由同一索引病例报告的伴侣间的聚类效应进行调整，我们评估了3个感兴趣的结果（伴侣通知、HIV检测和HIV阳性）与索引病例及其伴侣的人口统计学特征、风险行为、地理区域和服务年份之间的关联。
总共51368名性伴侣和/或共用针头伴侣与33524名索引病例相匹配。在应通知的伴侣中，97.2%被告知其可能暴露于HIV，52.3%接受了HIV检测。在21842名被告知且接受检测的伴侣中，23.8%被新诊断出感染HIV。伴侣通知、HIV检测和HIV阳性与伴侣及索引病例的特征（单独和交互）、地理区域和服务年份均相关。
通过CDC资助的卫生部门提供的伴侣服务项目在伴侣通知和识别伴侣中未确诊的HIV感染方面均有效。然而，被告知的伴侣中的HIV检测率仍然较低。实施解决HIV检测差距的策略有助于在美国终结HIV流行。
