Given its potential for reducing the proportion of people with human immunodeficiency virus (HIV) unaware of their diagnosis, partner notification for HIV has been underutilized. This study aimed to determine if the implementation of opt-out referral of men who have sex with men, newly diagnosed with HIV, to partner notification officers (PNO) increased the proportion of sexual partners notified.
In April 2013, all individuals newly diagnosed with HIV at the Melbourne Sexual Health Centre, Australia were referred to Department of Health PNO to facilitate partner notification. The number of sexual partners reported by men and the proportion contacted in the 12 months before (opt-in period) and after (opt-out period) this policy change were determined through review of the clinical PNO records.
Overall, 111 men were diagnosed with HIV during the study period. Compared with men in the opt-in period (n = 51), men in the opt-out period (n = 60) were significantly more likely to accept assistance from the PNO (12 [24%] vs 51 [85%]; P < 0.001). A significantly higher proportion of reported partners were notified with opt-out referral (85/185, 45.9%; 95% confidence interval, 38.6-53.4) compared with opt-in referral (31/252, 12.3%; 95% confidence interval, 8.5-17.0) (P < 0.001).
Opt-out referral to PNO was associated with a substantially higher proportion of partners at risk of HIV being contacted.
鉴于其在降低未意识到自身感染人类免疫缺陷病毒（HIV）的人群比例方面的潜力，HIV的性伴通知一直未得到充分利用。本研究旨在确定将新诊断为HIV的男男性行为者转介给性伴通知官员（PNO）并采用退出式转介方式是否会增加被通知的性伴比例。
2013年4月，澳大利亚墨尔本性健康中心所有新诊断为HIV的个体均被转介至卫生部的PNO，以促进性伴通知。通过查阅PNO的临床记录，确定在这一政策变更前（加入式时期）和后（退出式时期）12个月内男性报告的性伴数量以及被联系上的性伴比例。
总体而言，在研究期间有111名男性被诊断为HIV。与加入式时期的男性（n = 51）相比，退出式时期的男性（n = 60）明显更有可能接受PNO的协助（12 [24%] 对51 [85%]；P < 0.001）。与加入式转介相比，退出式转介被通知的报告性伴比例显著更高（85/185，45.9%；95%置信区间，38.6 - 53.4），而加入式转介为（31/252，12.3%；95%置信区间，8.5 - 17.0）（P < 0.001）。
转介给PNO的退出式方式与联系上更多有HIV感染风险的性伴比例相关。
