Assisted Partner Notification Services in Namibia: Comparison of Case-Finding in Persons With New and Previously Diagnosed Human Immunodeficiency Virus, and Success as a Platform for PrEP Referral.

Assisted partner notification services (APS) are widely implemented throughout sub-Saharan Africa. The effectiveness of APS among persons with previously diagnosed human immunodeficiency virus (HIV) infection is uncertain, and there are few published data on the success of integrating referrals for HIV preexposure prophylaxis (PrEP) into APS. Staff in 22 Namibian Ministry of Health and Social Service clinics offered APS to patients newly and previously diagnosed with HIV (index cases [ICs]) between October 2019 and June 2021. Counselors used a structured interview guide to elicit ICs' sex partners and biological children and assisted ICs to arrange testing of contacts. Contacts testing HIV-positive were linked to HIV services and those 14 years or older testing negative were offered PrEP. The primary outcome was the case-finding index (contacts testing HIV-positive ÷ ICs receiving APS). Staff provided APS to 1222 (78%) of 1557 newly diagnosed ICs eliciting 1155 sex partners and 649 biological children. Among 280 previously diagnosed ICs, 279 sex partners and 158 biological children were elicited. The case-finding index was higher among ICs with newly diagnosed HIV compared with previously diagnosed HIV (0.14 vs 0.09, P = 0.46), though this difference was not statistically significant. Most sex partners testing HIV-negative were initiated on PrEP (67% in sex partners from newly diagnosed ICs; 74% in sex partners from previously diagnosed ICs). Assisted partner notification services successfully identified sex partners and biological children with undiagnosed HIV infection when provided to both newly and previously diagnosed ICs. Integration of referral to PrEP resulted in many HIV-negative partners initiating PrEP.

Assisted Partner Notification Services Are Safe and Effective as They Are Brought to Scale in Mozambique.

The World Health Organization recommends that persons diagnosed with HIV be offered assisted partner notification services (APS). There are limited data on the safety of APS as implemented in public health programs. Three public health centers in Maputo, Mozambique, 2016-2019. Counselors offered APS to persons with newly diagnosed HIV and, as part of a program evaluation, prospectively assessed the occurrence of adverse events (AEs), including (1) pushing, abandonment, or yelling; (2) being hit; and (3) loss of financial support or being expelled from the house. Eighteen thousand nine hundred sixty-five persons tested HIV-positive in the 3 clinics, 13,475 (71%) were evaluated for APS eligibility, 9314 were eligible and offered APS, and 9219 received APS. Index cases (ICs) named 8933 partners without a previous HIV diagnosis, of whom 6137 tested and 3367 (55%) were diagnosed with HIV (case-finding index = 0.36). APS counselors collected follow-up data from 6680 (95%) of 7034 index cases who had untested partners who were subsequently notified; 78 (1.2%) experienced an AE. Among 270 ICs who reported a fear of AEs at their initial APS interview, 211 (78%) notified ≥1 sex partner, of whom 5 (2.4%) experienced an AE. Experiencing an AE was associated with fear of loss of support (odds ratio [OR] 4.28; 95% confidence interval [CI]: 1.50 to 12.19) and having a partner who was notified, but not tested (OR 3.47; 95% CI: 1.93 to 6.26). Case-finding through APS in Mozambique is high and AEs after APS are uncommon. Most ICs with a fear of AEs still elect to notify partners with few experiencing AEs.

Descriptive study: Feasibility of integrating hypertension screening into HIV assisted partner notification services model in Kenya.

Prevalence of hypertension (HTN) and human immunodeficiency virus (HIV) are high among men while screening rates are low. Assisted partner notification service is a strategy recommended by the World Health Organization that aims to increase HIV testing and treatment uptake and may present an opportunity to offer integrated HIV/HTN screening and treatment services. In this prospective cohort study, we assessed the feasibility of integrating HTN screening for male sexual partners of females newly tested HIV-positive in 10 health facilities in Kenya. Participants were notified of the exposure and offered HIV testing and HTN screening; if they accepted and tested positive for either HTN, HIV, or both, they were referred for care. HTN was defined as systolic blood pressure ≥ 140 mm Hg, diastolic blood pressure ≥ 90, or the use of antihypertensive medication. Among 1313 male partners traced, 99% accepted HIV testing and HTN screening. Overall, 4% were found to have HTN, 29% were in the pre-HTN stage, and 9% were HIV-positive. Only 75% had previously been screened for HTN compared to 95% who had previously tested for HIV. A majority preferred non-facility-based screening. The participants who refused HTN screening noted time constraints as a significant hindrance. HIV and HTN screening uptake was high in this hard-to-reach population of men aged 25 to 50. Although HTN rates were low, an integrated approach provided an opportunity to detect those with pre-HTN and intervene early. Strategic integration of HTN services within assisted partners services may promote and normalize testing by offering inclusive and accessible services to men.

The Organization, Content, and Case-Finding Effectiveness of HIV Assisted Partner Services in High HIV Morbidity Areas of the United States.

The contemporary effectiveness of assisted partner notification services (APS) in the United States is uncertain. State and local jurisdictions in the United States that reported ≥300 new HIV diagnoses in 2018 and were participating in the Ending the Epidemic Initiative. The study surveyed health departments to collect data on the content and organization of APS and aggregate data on APS outcomes for 2019. Analyses defined contact and case-finding indices (i.e., sex partners named and newly diagnosed per index case receiving APS) and estimated staff case-finding productivity. Sixteen (84%) of 19 jurisdictions responded to the survey, providing APS outcome data for 14 areas (74%). Most health departments routinely integrated APS with linkage of cases and partners to HIV care (88%) and pre-exposure prophylaxis (88%). A total of 19,164 persons were newly diagnosed with HIV in the 14 areas. Staff initiated APS investigations on 14,203 cases (74%) and provided APS to 9937 cases (52%). Cases named 6799 partners (contact index = 0.68), of whom 1841 (27%) had previously diagnosed HIV, 2202 (32%) tested HIV negative, 541 (8% of named and 20% of tested partners) were newly diagnosed with HIV, and 2215 (33%) were not known to have tested. Across jurisdictions, the case-finding index was 0.054 (median = 0.05, range 0.015-0.12). Health departments employed 292 full-time equivalent staff to provide APS. These staff identified a median of 2.0 new HIV infections per staff per year. APS accounted for 2.8% of new diagnoses in 2019. HIV case-finding resulting from APS in the United States is low.

Strategies for Optimising Uptake of Assisted Partner Notification Services Among Newly Diagnosed HIV Positive Adults at Ndirande Health Centre, Malawi

ABSTRACT UNAIDS Fast-Track goals for 2025 include ensuring that 95% of the people with HIV know their HIV status. In 2019, the Malawi Ministry of Health introduced its approach for achieving this: an active index testing (AIT) policy with assisted partner notification services (APNS). Under this policy, health centers can actively reach out to a contact of newly-diagnosed HIV positive client (the index) to offer voluntary HIV testing services. However, APNS uptake has been sub-optimal at many health facilities. This qualitative study considers strategies to optimize the uptake of APNS among newly-diagnosed HIV positive clients at Ndirande Health Center in Blantyre, Malawi. We conducted in-depth interviews, between February and April 2020, with 24 participants, including new HIV positive index clients, their sexual partners, and key health workers. We employ a maximum variation purposive sampling technique. Thematic inductive and deductive data analysis was done manually according to the social-ecological model. Interviewees discussed various strategies for optimizing APNS uptake among newly diagnosed HIV-infected clients. Interpersonal strategies included maximizing the use of client profiling techniques and sensitization on APNS to create demand. Institutional-level strategies were also suggested, such as providing transportation for home visits, strengthening referral notification approaches, and additional training for health workers. Policy-level recommendations included introducing home-based partner testing and intensifying use of partner notification slips. APNS is a key strategy to maximize HIV case identification. However, achieving optimal APNS in Malawi requires strengthening existing strategies and conducting additional research to identify other APNS strategies tailored to the local context.

Brief Report: Active HIV Case Finding in the City of Kigali, Rwanda: Assessment of Voluntary Assisted Partner Notification Modalities to Detect Undiagnosed HIV Infections.

Voluntary assisted partner notification (VAPN) services that use contract, provider, or dual referral modalities may be efficient to identify individuals with undiagnosed HIV infection. We aimed to assess the relative effectiveness of VAPN modalities in identifying undiagnosed HIV infections. VAPN was piloted in 23 health facilities in Kigali, Rwanda. We identified individuals with a new HIV diagnosis before antiretroviral therapy initiation or individuals on antiretroviral therapy (index cases), who reported having had sexual partners with unknown HIV status, to assess the association between referral modalities and the odds of identifying HIV-positive partners using a Bayesian hierarchical logistic regression model. We adjusted our model for important factors identified through a Bayesian variable selection. Between October 2018 and December 2019, 6336 index cases were recruited, leading to the testing of 7690 partners. HIV positivity rate was 7.1% (546/7690). We found no association between the different referral modalities and the odds of identifying HIV-positive partners. Notified partners of male individuals (adjusted odds ratio 1.84; 95% credible interval: 1.50 to 2.28) and index cases with a new HIV diagnosis (adjusted odds ratio 1.82; 95% credible interval: 1.45 to 2.30) were more likely to be infected with HIV. All 3 VAPN modalities were comparable in identifying partners with HIV. Male individuals and newly diagnosed index cases were more likely to have partners with HIV. HIV-positive yield from index testing was higher than the national average and should be scaled up to reach the first UNAIDS-95 target by 2030.

HIV Positive status disclosure to sexual partners: a qualitative study to explore experiences and challenges among clients attending HIV care services in North-Western Tanzania

ABSTRACT HIV status disclosure rates to sexual partners are low in Tanzania, despite the benefits it confers to both partners. This qualitative study drew on the Disclosure Decision Model to explore the decision by people living with HIV (PLHIV) to disclose, or not, their HIV status to their partner. Six focus group discussions and thirty in-depth interviews were conducted in Mwanza, Tanzania in 2019 with PLHIV. Topics covered decision-making around disclosure and disclosure experiences. Thematic content analysis was conducted. Most respondents reported having disclosed their status to their partners. Disclosure was reported to facilitate or hinder the attainment of social goals including having intimate relationships, raising a family, relief from distress and accessing social support. Decisions made by PLHIV about whether to disclose their status were made after weighing up the perceived benefits and risks. The sense of liberty from a guilty conscious, and not “living a lie” were perceived as benefits of disclosure, while fears of stigma, family break-up or abandonment were perceived as risks. Many participants found disclosure was beneficial in promoting their adherence to treatment and clinic appointments. Interventions to support PLHIV with disclosure should include enhanced counselling, strengthening HIV support groups and enhanced assisted partner notification services.

Developing HIV assisted partner notification services tailored to Mexican key populations: a qualitative approach

BackgroundAssisted partner notification services (APNS) may increase HIV testing, early diagnosis, and treatment, but they are not formally implemented in Mexico, where the HIV epidemic is concentrated in men who have sex with men (MSM) and transwomen (TW). This study aimed to explore the awareness of and need for HIV partner notification, as well as to outline potential strategies for APNS based on identified barriers and facilitators.MethodsWe conducted semi-structured interviews to explore partner notification with MSM, TW, and counselors. Afterwards, brainstorm sessions were carried out to produce strategies for implementing APNS.ResultsMost participants reported experiences with informal partner notification and serostatus disclosure, but not with APNS. Only one counselor indicated assisting notification systematically. The main barriers for notifying or disclosing mentioned by both MSM and TW included fear of (violent) reactions, discrimination and lacking contact information of casual partners. Participants thought it was easier to inform a formal partner, conditional of being well informed about HIV. Given current stigma and lack of awareness, it was suggested that APNS should be preceded by HIV awareness efforts, and be provided by counselors or peers to mitigate potential rejection or violent reactions.ConclusionsWhile APNS are not formally implemented in Mexico, all participants supported the service, indicating that APNS could potentially enhance early HIV diagnosis in Mexico. Strategies to implement such services need to be flexible addressing the individual needs of participants, guaranteeing the safety of more vulnerable participants.

High Acceptability of Assisted Partner Notification Services Among HIV-Positive Females in Kenya: Results From an Ongoing Implementation Study.

Assisted partner services (aPS) involves notification and HIV testing for sexual partners of persons diagnosed HIV-positive (index clients). Because the impact of aPS is contingent on high acceptance, we assessed characteristics and reasons for nonenrollment among female index clients in an ongoing scale-up project. We analyzed data from HIV-positive females offered aPS in 31 facilities from May 2018 to August 2019. We compared sociodemographic characteristics by aPS enrollment (accepted, refused, and ineligible) and used multivariate binomial regression to assess associations between demographics and refusal. Twenty-four thousand four hundred eighteen females received HIV testing and 1050 (4.3%) tested HIV-positive; 839 females enrolled in aPS (80%), 59 refused (6%), and 152 were ineligible (14%). APS uptake did not differ by age, testing history, or testing type (provider initiated vs. client initiated). Females refusing aPS were more likely to have completed secondary school [adjusted relative risk (aRR) 2.03, 95% confidence interval (CI): 1.13 to 2.82] and be divorced/separated (aRR: 3.09, 95% CI: 1.39 to 6.86) or single (aRR: 2.66, 95% CI: 1.31 to 5.42) compared with married/cohabitating. Reasons for refusing aPS included not feeling emotionally ready (31%) and reporting no sexual partners in past 3 years (22%). Reasons for ineligibility included fear or risk of intimate partner violence (9%), previous HIV diagnosis (9%), or insufficient time for aPS provision (3%). APS has high acceptability among HIV-positive females regardless of age or testing history. More counseling may be needed to increase uptake among females with higher education and those who are separated/single. Follow-up for females not emotionally ready or who had insufficient time for aPS in their clinic visit can improve coverage.

Factors associated with Assisted Partner Notification Services in Seme and Kisumu west sub counties, Kenya.

Background: Assisted partner notification service (aPNS) is a public health strategy which entails a health worker interviewing persons identified with an STI (index cases) about their sexual partner(s) and/or contacts and then providing the index case with some level of assistance notifying their partner(s) and assuring their testing. Assisted partner notification services was implemented, as a public health intervention to identify individuals' new HIV infections and facilitate linkage to care. Methods: Participants aged 18 years and above were selected and enrolled in the study through simple random sampling. Participants provided written informed consent to participate in the study. Logistic regression (bivariate and multivariate) analysis was performed on data to determine factors associated with participation in aPNS. Backward stepwise elimination was used to select variables to be included in the multivariate level to estimate the odds ratios (OR). Results: We enrolled 423 participants of which 62.5 % were aged 18-25 and women (n=228, 54.5%) and men (n=190, 45.5%). Overall participation in aPNS was 69.1%. The predictors of participation in aPNS were occupation and residence. The odds of participating in aPNS was higher for those who practiced peasantry (aOR=2.04; 95% CI, 1.08-3.85, p=0.029). However, those in the urban were less likely to participate in aPNS compared to those in the rural setting notification (aOR=0.57; 95% CI, 0.33-0.98, p=0.042) and those employed were less likely to participate in aPNS compared to those unemployed (aOR=0.56; 95% CI, 0.33-0.95, p=0.032). Conclusion: There is need to target interventions targeting assisted partner notification in the urban settings and among those in the workforce.

A Novel HIV-1 RNA Testing Intervention to Detect Acute and Prevalent HIV Infection in Young Adults and Reduce HIV Transmission in Kenya: Protocol for a Randomized Controlled Trial

BackgroundDetection and management of acute HIV infection (AHI) is a clinical and public health priority, and HIV infections diagnosed among young adults aged 18 to 39 years are usually recent. Young adults with recent HIV acquisition frequently seek care for symptoms and could potentially be diagnosed through the health care system. Early recognition of HIV infection provides considerable individual and public health benefits, including linkage to treatment as prevention, access to risk reduction counseling and treatment, and notification of partners in need of HIV testing.ObjectiveThe Tambua Mapema Plus study aims to (1) test 1500 young adults (aged 18-39 years) identified by an AHI screening algorithm for acute and prevalent (ie, seropositive) HIV, linking all newly diagnosed HIV-infected patients to care and offering immediate treatment; (2) offer assisted HIV partner notification services to all patients with HIV, testing partners for acute and prevalent HIV infection and identifying local sexual networks; and (3) model the potential impact of these two interventions on the Kenyan HIV epidemic, estimating incremental costs per HIV infection averted, death averted, and disability-adjusted life year averted using data on study outcomes.MethodsA modified stepped-wedge design is evaluating the yield of this HIV testing intervention at 4 public and 2 private health facilities in coastal Kenya before and after intervention delivery. The intervention uses point-of-care HIV-1 RNA testing combined with standard rapid antibody tests to diagnose AHI and prevalent HIV among young adults presenting for care, employs HIV partner notification services to identify linked acute and prevalent infections, and follows all newly diagnosed patients and their partners for 12 months to ascertain clinical outcomes, including linkage to care, antiretroviral therapy (ART) initiation and virologic suppression in HIV-infected patients, and pre-exposure prophylaxis uptake in uninfected individuals in discordant partnerships.ResultsEnrollment started in December 2017. As of April 2020, 1374 participants have been enrolled in the observation period and 1500 participants have been enrolled in the intervention period, with 13 new diagnoses (0.95%) in the observation period and 37 new diagnoses (2.47%), including 2 AHI diagnoses, in the intervention period. Analysis is ongoing and will include adjusted comparisons of the odds of the following outcomes in the observation and intervention periods: being tested for HIV infection, newly diagnosed with prevalent or acute HIV infection, linked to care, and starting ART by week 6 following HIV diagnosis. Participants newly diagnosed with acute or prevalent HIV infection in the intervention period are being followed for outcomes, including viral suppression by month 6 and month 12 following ART initiation and partner testing outcomes.ConclusionsThe Tambua Mapema Plus study will provide foundational data on the potential of this novel combination HIV prevention intervention to reduce ongoing HIV transmission in Kenya and other high-prevalence African settings.Trial RegistrationClinicalTrials.gov NCT03508908; https://clinicaltrials.gov/ct2/show/NCT03508908International Registered Report Identifier (IRRID)DERR1-10.2196/16198

Exploring the acceptability of HIV partner notification in prisons: Findings from a survey of incarcerated people living with HIV in Indonesia.

Assisted HIV partner notification services provide a safe and effective way for people living with HIV (PLHIV) to inform their partners about the possibility of exposure and to offer them testing, treatment, and support. This study examined whether or not PLHIV in prison might be willing to participate in assisted HIV partner notification services and their reasons for and against disclosing their HIV-positive status to their partners. PLHIV (n = 150) recruited from Jakarta’s two largest all-male prisons completed an interviewer-administered questionnaire collecting demographic and risk behavior data, and attitudes toward HIV disclosure and partner services. Among those who were sexually active and/or injecting drugs before incarceration, two-thirds (66.4%, 91/137) endorsed provider referral as an acceptable way to notify their sex partners, and nearly three quarters (72.4%, 89/123) endorsed provider referral to notify their drug-injecting partners. Only a quarter (25.1%) of participants reported that their main sex partner had ever received an HIV test. Participants with anticipated stigma were less likely to endorse provider referral for sex partners (adjusted odds ratio [aOR] = 0.58, 95% CI: 0.35, 0.96) and drug-injecting partners (aOR = 0.54, 95% CI: 0.29, 1.00). Relationship closeness was associated with higher odds of endorsing provider referral for drug-injecting partners (aOR = 2.08, 95% CI: 1.25, 3.45). Protecting partners from infection and a moral duty to inform were main reasons to disclose, while stigma and privacy concerns were main reasons not to disclose. Most incarcerated PLHIV have at-risk partners in the community who they would be willing to notify if provided with assistance. Assisted partner notification for prison populations offers a promising public health approach to accelerate diagnosis, treatment, and prevention of HIV infection in the community, particularly among women.

Community-led HIV testing services including HIV self-testing and assisted partner notification services in Vietnam: lessons from a pilot study in a concentrated epidemic setting.

IntroductionThe HIV epidemic in Vietnam is concentrated in key populations and their partners – people who inject drugs, men who have sex with men, sex workers and partners of people living with HIV. These groups have poor access to and uptake of conventional HIV testing services (HTS). To address this gap, lay provider‐ and self‐testing and assisted partner notification (aPN) were introduced and delivered by the community. We explored the feasibility and effectiveness of implementing aPN as part of community testing services for key populations.MethodsLay provider testing and self‐testing was started in January 2017, and targeted key populations and their partners. Since July 2017, aPN was introduced. HTS was offered at drop‐in houses or coffee shops in Thai Nguyen and Can Tho provinces. All self‐testing was assisted and observed by peer educators. Both in‐person and social network methods were used to mobilize key populations to test for HIV and offer HTS to partners of people living with HIV. Client‐level data, including demographic information and self‐reported risk behaviour, were collected on site by peer educators.ResultsBetween January 2017 and May 2018, 3978 persons from key populations were tested through community‐led HTS; 66.7% were first‐time testers. Of the 3978 clients, 3086 received HTS from a lay provider and 892 self‐tested in the presence of a lay provider. Overall, 245 (6.2% of tested clients) had reactive results, 231 (94.3%) were confirmed to be HIV positive; 215/231 (93.1%) initiated antiretroviral therapy (ART). Of 231 adult HIV‐positive clients, 186 (80.5%) were provided voluntary aPN, and 105 of their partners were contacted and received HTS. The ratio of partners who tested for HIV per index client was 0.56. Forty‐four (41.9%) partners of index clients receiving HTS were diagnosed with HIV, 97.7% initiated ART during the study period. No social harm was identified or reported.ConclusionsIncluding aPN as part of community‐led HTS for key populations and their partners is feasible and effective, particularly for reaching first‐time testers and undiagnosed HIV clients. Scale‐up of aPN within community‐led HTS for key populations is essential for achieving the United Nations 90‐90‐90 targets in Vietnam.

Assisted partner notification services for patients receiving HIV care and treatment in an HIV clinic in Nairobi, Kenya: a qualitative assessment of barriers and opportunities for scale-up.

IntroductionIdentifying HIV‐positive individuals is increasingly recognized as one of the most important and most challenging of the UNAIDS 90‐90‐90 goals. Assisted partner notification services (aPNS) involves tracing and offering HIV testing to partners of HIV‐positive individuals, and is effective and safe when provided to newly diagnosed HIV‐positive patients. Voluntary aPNS is now part of the World Health Organization's guidelines for HIV prevention and care. However, uptake of aPNS is significantly lower among adults with established HIV infection already engaged in care compared to newly diagnosed individuals. We sought to describe barriers encountered and potential opportunities to providing aPNS to established patients living with HIV.MethodsWe conducted focus group discussions and in‐depth interviews at Nairobi's largest public HIV clinic in April to May 2016 to elucidate barriers to and opportunities for aPNS among established patients engaged in HIV care. Participants included HIV‐positive adults in care, their partners, and healthcare workers (HCWs). Qualitative data analysis took a grounded theory approach.ResultsBarriers to aPNS fell under three main categories. Fear of disclosure to partners included concerns over relationship repercussions, loss of trust, blame and violence. Stigma and discrimination were described in the healthcare setting, at church and in general society. Participants described difficulties approaching communication, including cultural barriers and differences in education. For almost every barrier a potential solution was also identified, and a barrier‐opportunity relationship emerged. Opportunities included using couples testing centres to aid in disclosure, focusing on the ambiguous introduction of the infection, and sensitization of HCWs and community leaders.ConclusionsaPNS among established HIV patients is associated with different barriers and opportunities than aPNS among newly diagnosed patients, and HCWs should build their capacity to support aPNS in this population. There is a strong need for increased training and sensitization on the use of aPNS in different circumstances and for different clients, taking into consideration factors such as timing of partner notification, characteristics of the relationship and duration of knowledge discordance. The overall success of this intervention among populations living with HIV may rely on customization of services and key messages to meet the patients’ specific needs.

Assisted HIV partner notification services in resource-limited settings: experiences and achievements from Cameroon.

IntroductionIn 2007, the Cameroon Baptist Convention Health Services (CBCHS) initiated an assisted partner notification services (aPNS) public health programme to increase HIV case identification and reduce HIV incidence in the most affected regions of Cameroon. We describe large‐scale implementation of aPNS and overall programmatic achievements in a resource‐limited setting through 2015.Methods CBCHS trained health advisors (HAs) from 16 CBCHS facilities and 22 non‐CBCHS facilities to integrate aPNS into their existing jobs in five of the ten Cameroon regions. HAs recorded basic demographic, clinical and risk factor information from consenting index persons (IPs) and similar information about their sexual partners’/contact persons (CPs) on interview records and aPNS registers. These data were entered into an Epi‐Info database. HAs provided pre‐test counselling to CPs and offered them HIV testing in their home or other location. HAs educated IPs and CPs on HIV prevention and risk reduction, and referred IPs and HIV positive CPs to HIV care and treatment centres. Starting in 2014, HAs re‐interviewed IPs 30 days after their initial aPNS interview to ascertain instances of social harms following partner notification. Continuous predictor and outcome variables were summarized using median and interquartile range, while categorical variables were summarized using percentages from 2007 to 2015.ResultsA total of 18,730 IPs (71% women) received aPNS over nine years. IPs identified 21,057 CPs (67% men) (mean CP/IP 1.12), of whom 12,867 (61.1%) were notified of their exposure to HIV. A total of 9202 (71.5% of notified CPs) tested for HIV, 4764 (51.8%) of whom tested HIV positive (number of IPs needed to interview = 3.9); 3112 (65.3%) HIV‐positive partners were referred to HIV care and treatment centres. Of the 976 IPs receiving aPNS in 2014 to 2015, for whom follow‐up data were available, 11 (1.1%) reported physical intimate partner violence from CPs. Thus, 44.3% of 1224 CPs were notified through provider referral. Of the 784 CPs who tested for HIV, 157 were newly diagnosed and the overall HIV prevalence was 41.6% (326/784).Conclusions aPNS is feasible, can be brought to scale, yields a high level of case identification, and is infrequently associated with social harms and intimate partner violence.

Assessing the Effectiveness and Feasibility of Voluntary Assisted Partner Notification Services

Assessing the Effectiveness and Feasibility of Voluntary Assisted Partner Notification Services

Improving HIV test uptake and case finding with assisted partner notification services.

Objective:Despite the enormous expansion of HIV testing services (HTS), an estimated 40% of people with HIV infection remain undiagnosed. To enhance the efficiency of HTS, new approaches are needed. The WHO conducted a systematic review on the effectiveness of assisted partner notification in improving HIV test uptake and diagnosis, and the occurrence of adverse events, to inform the development of normative guidelines.Methods:We systematically searched five electronic databases through June 2016. We also contacted experts in the field and study authors for additional information where needed. Eligible studies compared assisted HIV partner notification services to passive or no notification. Where multiple studies reported comparable outcomes, meta-analysis was conducted using a random-effects model to produce relative risks (RRs) or risk ratios and 95% confidence intervals (CIs).Results:Of 1742 citations identified, four randomized controlled trials and six observational studies totalling 5150 index patients from eight countries were included. Meta-analysis of three individually randomized trials showed that assisted partner notification services resulted in a 1.5-fold increase in HTS uptake among partners compared with passive referral (RR = 1.46; 95% CI: 1.22–1.75; I2 = 0%). The proportion of HIV-positive partners was 1.5 times higher with assisted partner notification than with passive referral (RR = 1.47; 95% CI: 1.12–1.92; I2 = 0%). Few instances of violence or harm occurred.Conclusion:Assisted partner notification improved partner testing and diagnosis of HIV-positive partners, with few reports of harm. WHO strongly recommends voluntary assisted HIV partner notification services to be offered as part of a comprehensive package of testing and care.

Assisted partner notification services to augment HIV testing and linkage to care in Kenya: study protocol for a cluster randomized trial.

BackgroundHIV case-finding and linkage to care are critical for control of HIV transmission. In Kenya, >50% of seropositive individuals are unaware of their status. Assisted partner notification is a public health strategy that provides HIV testing to individuals with sexual exposure to HIV and are at risk of infection and disease. This parallel, cluster-randomized controlled trial will evaluate the effectiveness, cost-effectiveness, and feasibility of implementing HIV assisted partner notification services at HIV testing sites (clusters) in Kenya.Methods/designEighteen sites were selected among health facilities in Kenya with well-established, high-volume HIV testing programs, to reflect diverse communities and health-care settings. Restricted randomization was used to balance site characteristics between study arms (n = 9 per arm). Sixty individuals testing HIV positive (‘index partners’) will be enrolled per site (inclusion criteria: ≥18 years, positive HIV test at a study site, willing to disclose sexual partners, and never enrolled for HIV care; exclusion criteria: pregnancy or high risk of intimate partner violence). Index partners provide names and contact information for all sexual partners in the past 3 years. At intervention sites, study staff immediately contact sexual partners to notify them of exposure, offer HIV testing, and link to care if HIV seropositive. At control sites, passive partner referral is performed according to national guidelines, and assisted partner notification is delayed by 6 weeks. Primary outcomes, assessed 6 weeks after index partner enrollment and analyzed at the cluster level, are the number of partners accepting HIV testing and number of HIV infections diagnosed and linked to care per index partner. Secondary outcomes are the incremental cost-effectiveness of partner notification and the costs of identifying >1 partner per index case. Participants are closely monitored for adverse outcomes, particularly intimate partner violence. The study is unblinded due to practical limitations.DiscussionThis rigorously designed trial will inform policy decisions regarding implementation of HIV partner notification services in Kenya, with possible application to other parts of sub-Saharan Africa. Examination of effectiveness and cost-effectiveness in diverse settings will enable targeted application and define best practices.Trial registrationClinicalTrials.gov NCT01616420.
