An estimated 30% of HIV cases in the European Union are not aware of their serological status. This study aimed to assess the effectiveness of a pilot HIV partner notification program.
HIV cases diagnosed between January 2012 and June 2013 at two healthcare settings in Barcelona were invited to participate in a prospective survey. We identified process and outcome measures to evaluate this partner notification program, including the number of partners identified per interviewed index case, the proportion of partners tested for HIV as a result of the partner notification, and the proportion of new HIV diagnoses among their sex or needle-sharing partners.
Of the 125 index cases contacted, 108 (86.4%) agreed to provide information about partners. A total of 199 sexual partners were identified (1.8 partners per interviewed index case). HIV outcome was already known for 58 partners (70.7% were known to be HIV-positive), 141 partners were tested as result of partner notification, and 26 were newly diagnosed with HIV. The case-finding effectiveness of the program was 18.4%.
This pilot program provides evidence of the effectiveness of a partner notification program implemented in healthcare settings. This active partner notification program was feasible, acceptable to the user, and identified a high proportion of HIV-infected patients previously unaware of their status.
欧盟约有 30%的艾滋病毒感染者不知道自己的血清学状况。本研究旨在评估一项试点艾滋病毒伙伴通知计划的有效性。
在巴塞罗那的两个医疗保健机构，邀请在 2012 年 1 月至 2013 年 6 月期间被诊断为艾滋病毒的病例参与前瞻性调查。我们确定了评估该伙伴通知计划的过程和结果指标，包括每例接受采访的索引病例所确定的伙伴数量、因伙伴通知而接受艾滋病毒检测的伙伴比例，以及他们的性伴侣或共用针头的伙伴中新诊断出的艾滋病毒病例比例。
接触的 125 例索引病例中，有 108 例（86.4%）同意提供有关伙伴的信息。总共确定了 199 个性伴侣（每个接受采访的索引病例 1.8 个伴侣）。58 个性伴侣的艾滋病毒结果已经知晓（70.7%已知为艾滋病毒阳性），141 个性伴侣因伙伴通知而接受了检测，26 个新诊断出艾滋病毒。该计划的病例发现效果为 18.4%。
该试点计划为在医疗保健环境中实施的伙伴通知计划的有效性提供了证据。这种主动的伙伴通知计划是可行的，为用户所接受，并发现了很大比例的以前不知道自己状况的艾滋病毒感染者。
