Background: Long-acting reversible contraception (LARC) is highly effective at preventing pregnancy. However, in sub-Saharan Africa, LARC education for clients is relatively limited and providers are often not skilled in their insertion. Before 2009, only 1% of family planning clients in Rwanda received an LARC. Materials and Methods: We trained Rwandan government clinic nurses to promote, insert, and remove copper intrauterine devices (IUDs) and hormonal implants. Training started in two large urban clinics, and those nurses trained three successive waves of clinic nurses. Initial LARC promotions were clinic based, but in 2015 included community-based promotions in eight clinics. We compare IUD and implant insertions by year and clinic and discuss implementation successes/obstacles. Results: From 2009 to 2016, 222 nurses from 21 government clinics were LARC trained. The nurses performed 36,588 LARC insertions (19% IUD, 81% implant). LARC insertions increased over time, peaking at 8,897 in 2013. However, in 2014, the number dropped to 4,018 after closure of one large clinic, funding discontinuation, and supply stock-outs. With new funding in 2015, insertions increased reaching 8,218 in 2016. Catholic and non-Catholic and rural and urban clinics performed similarly, whereas clinics affiliated with community-based promotions performed better (p > 0.05). Between 2012 and 2014, 13% of family planning initiators chose the implant and 4% the IUD. Conclusions: LARC supply–demand services increased the proportion of family planning initiators choosing LARC to 17%. Challenges included inconsistent funding, irregular supplies, and staff turnover. Rural and Catholic clinics performed as well as urban and non-Catholic clinics. Concerted efforts to improve IUD uptake are needed.

BACKGROUND: Few family planning programs in Africa base demand creation and service delivery on theoretical models. Motivational interviewing (MI) is a counseling modality that facilitates reflection on the benefits and disadvantages of a health outcome to encourage behavior change. OBJECTIVES: We evaluate a couples-focused joint family planning and HIV counseling intervention using motivational interviewing (MI) to enhance uptake of long acting reversible contraception (LARC, Paragard copper intra-uterine device (IUD) or Jadelle hormonal implant) among Rwandan couples. STUDY DESIGN: In this experimental study, couples receiving care at eight government health clinics in Kigali, the capital city, were referred from a parent study of couples that did not want more children or wanted to wait at least two years for their next pregnancy. LARC methods were offered on site following joint HIV testing and family planning counseling. At the first follow-up visit one month after enrollment in the parent study, couples who had not yet chosen a LARC method were interviewed separately using MI, then brought together and again offered LARC. RESULTS: Following MI, 78/229 (34%) couples requested a LARC method (68 implant and 10 IUD). LARC uptake after MI was associated with the woman being Catholic (vs. Protestant/Muslim/Other, aOR 2.87, 95% C.I. 1.19-6.96, p=0.019) or having an income (vs. no income aOR 2.54, 95% C.I. 1.12-5.73, p=0.025); the couple having previously discussed LARC (aOR 8.38, 95% C.I. 2.54-27.59, p=0.0005); either partner believing that unplanned pregnancy was likely with their current method (aOR 6.67, 95% C.I. 2.77-16.11, p<0.0001) or that they might forget to take or make an appointment for their current method (aOR 4.04, 95% C.I. 1.32-12.34, p=0.014). Neither partner mentioning that condoms also prevent HIV/sexually transmitted infection (STI) was associated with LARC uptake (aOR 2.86, 95% C.I. 1.17-7.03, p=0.022), as was the woman citing long-term duration of action of the implant as an advantage (aOR ...

Introduction: Most HIV infections in Africa are acquired by married/cohabiting adults and WHO recommends couple's voluntary HIV counseling and testing (CVCT) for prevention. The handover from NGO-sponsored weekend CVCT to government-sponsored services in routine weekday antenatal care (ANC) and individual voluntary testing and counseling (VCT) services in Zambia's two largest cities from 2009–2015 is described. Methods: Government clinic counselors were trained to provide CVCT, and along with community health workers they promoted CVCT services in their clinic and surrounding areas. When client volume exceeded the capacity of on-duty staff in ANC and VCT, non-governmental organization (NGO) subsidies were offered for overtime pay. Results: Implementation of routine CVCT services varied greatly by clinic and city. The 12 highest volume clinics were examined further, while 13 clinics had CVCT numbers that were too low to warrant further investigation. In Lusaka, the proportion of pregnant women whose partners were tested rose from 2.6% in 2009 to a peak of 26.2% in 2012 and 24.8% in 2015. Corresponding reports in Ndola were 2.0% in 2009, 17.0% in 2012 and 14.5% in 2015. Obstacles to CVCT included: limited space and staffing, competing priorities, record keeping not adapted for couples, and few resources for promotion and increasing male involvement. Conflicting training models for 'partner testing' with men and women separately vs. CVCT with joint post-test counseling led to confusion in reporting to district health authorities. Discussion: A focused and sustained effort will be required to reach a meaningful number of couples with CVCT to prevent heterosexual and perinatal HIV transmission. Establishing targets and timelines, funding for dedicated and appropriately trained staff, adoption of standardized data recording instruments with couple-level indicators, and expansion of community and clinic-based promotions using proven models are recommended.

Background: Though the Rwandan Ministry of Health (MOH) prioritizes the scale-up of postpartum family planning (PPFP) programs, uptake and sustainability of PPFP services in Rwanda are low. Furthermore, highly effective long-acting reversible contraceptive method use (LARC), key in effective PPFP programs, is specifically low in Rwanda. We previously pilot tested a supply-demand intervention which significantly increased the use of postpartum LARC (PPLARC) in Rwandan government clinics. In this protocol, we use an implementation science framework to test whether our intervention is adaptable to large-scale implementation, cost-effective, and sustainable. Methods: In a type 2 effectiveness-implementation hybrid study, we will evaluate the impact of our PPFP intervention on postpartum LARC (PPLARC) uptake in a clinic-randomized trial in 12 high-volume health facilities in Kigali, Rwanda. We will evaluate this hybrid study using the RE-AIM framework. The independent effectiveness of each PPFP demand creation strategy on PPLARC uptake among antenatal clinic attendees who later deliver in a study facility will be estimated. To assess sustainability, we will assess the intervention adoption, implementation, and maintenance. Finally, we will evaluate intervention cost-effectiveness and develop a national costed implementation plan. Discussion: Adaptability and sustainability within government facilities are critical aspects of our proposal, and the MOH and other local stakeholders will be engaged from the outset. We expect to deliver PPFP counseling to over 21,000 women/couples during the project period. We hypothesize that the intervention will significantly increase the number of stakeholders engaged, PPFP providers and promoters trained, couples/clients receiving information about PPFP, and PPLARC uptake comparing intervention versus standard of care. We expect PPFP client satisfaction will be high. Finally, we also hypothesize that the intervention will be cost-saving relative to the standard of care. This ...

OBJECTIVE: To present the incremental cost from the payer's perspective and effectiveness of couples' family planning counseling (CFPC) with long-acting reversible contraception (LARC) access integrated with couples' voluntary HIV counseling and testing (CVCT) in Zambia. This integrated program is evaluated incremental to existing individual HIV counseling and testing and family planning services. DESIGN: Implementation and modeling SETTING: 55 government health facilities in Zambia SUBJECTS: Patients in government health facilities INTERVENTION: Community health workers and personnel promoted and delivered integrated CVCT+CFPC from March 2013-September 2015. MAIN OUTCOME MEASURES: We report financial costs of actual expenditures during integrated program implementation and outcomes of CVCT+CFPC uptake and LARC uptake. We model primary outcomes of cost-per-: adult HIV infections averted by CVCT, unintended pregnancies averted by LARC, couple-years of protection against unintended pregnancy by LARC, and perinatal HIV infections averted by LARC. Costs and outcomes were discounted at 3%/year. RESULTS: Integrated program costs were $3,582,186 (2015 USD), 82,231 couples received CVCT+CFPC, and 56,409 women received LARC insertions. The program averted an estimated 7,165 adult HIV infections at $384/adult HIV infection averted over a 5-year time horizon. The program also averted 62,265 unintended pregnancies and was cost-saving for measures of cost-per-unintended pregnancy averted, cost-per-couple-year of protection against unintended pregnancy, and cost-per-perinatal HIV infection averted assuming 3 years of LARC use. CONCLUSIONS: Our intervention was cost-savings for CFPC outcomes and CVCT was effective and affordable in Zambia. Integrated couples-focused HIV and family planning was feasible, affordable, and leveraged HIV and unintended pregnancy prevention.

INTRODUCTION: Postpartum (PP) family planning is critical to reduce maternal-child mortality, abortion, and unintended pregnancy. As in most countries, the majority of PP women in Rwanda have an unmet need for postpartum family planning (PPFP). In particular, increasing use of the highly effective PP long-acting reversible contraceptive (LARC) methods (the intrauterine device [IUD] and implant) is a national priority. We developed a muti-level intervention to increase supply and demand for PPFP services in Kigali, Rwanda. METHODS: We implemented our intervention (which included PPFP promotional counseling for clients, training for providers, and Ministry of Health stakeholder involvement) in six government health facilities from Aug 2017-Oct 2018. While increasing knowledge and uptake of the IUD was a primary objective, all contraceptive method options were discussed and made available. Here, we report a secondary analysis of PP implant uptake and present already published data on PP IUD uptake for reference. RESULTS: Over a 15-month implementation period, 12,068 women received PPFP educational counseling and delivered at a study facility. Of these women, 1252 chose a PP implant (10.4% uptake) and 3372 chose a PPIUD (27.9% uptake). On average providers at our intervention facilities inserted 83.5 PP implants/month and 224.8 PPIUDs/month. Prior to our intervention, 30 PP implants/month and 8 PPIUDs/month were inserted at our selected facilities. Providers reported high ease of LARC insertion, and clients reported minimal insertion anxiety and pain. CONCLUSIONS: PP implant and PPIUD uptake significantly increased after implementation of our multi-level intervention. PPFP methods were well-received by clients and providers.

BACKGROUND: When integrated with couples' voluntary HIV counselling and testing (CVCT), family planning including long acting reversible contraceptives (LARC) addresses prongs one and two of prevention of mother-to-child transmission (PMTCT). METHODS: In this observational study, we enrolled equal numbers of HIV concordant and discordant couples in four rural and four urban clinics, with two Catholic and two non-Catholic clinics in each area. Eligible couples were fertile, not already using a LARC method, and wished to limit or delay fertility for at least 2 years. We provided CVCT and fertility goal-based family planning counselling with the offer of LARC and conducted multivariate analysis of clinic, couple, and individual predictors of LARC uptake. RESULTS: Of 1290 couples enrolled, 960 (74%) selected LARC: Jadelle 5-year implant (37%), Implanon 3-year implant (26%), or copper intrauterine device (IUD) (11%). Uptake was higher in non-Catholic clinics (85% vs. 63% in Catholic clinics, p < 0.0001), in urban clinics (82% vs. 67% in rural clinics, p < 0.0001), and in HIV concordant couples (79% vs. 70% of discordant couples, p = .0005). Religion of the couple was unrelated to clinic religious affiliation, and uptake was highest among Catholics (80%) and lowest among Protestants (70%) who were predominantly Pentecostal. In multivariable analysis, urban location and non-Catholic clinic affiliation, Catholic religion of woman or couple, younger age of men, lower educational level of both partners, non-use of condoms or injectable contraception at enrollment, prior discussion of LARC by the couple, and women not having concerns about negative side effects of implant were associated with LARC uptake. CONCLUSIONS: Fertility goal-based LARC recommendations combined with couples' HIV counselling and testing resulted in a high uptake of LARC methods, even among discordant couples using condoms for HIV prevention, in Catholic clinics, and in rural populations. This model successfully integrates prevention of HIV and ...

AbstractIntroductionThe chemokine receptor CCR5 is the main co‐receptor for R5‐tropic HIV‐1 variants. We have previously described a novel 24‐base pair deletion in the coding region of CCR5 among individuals from Rwanda. Here, we investigated the prevalence of hCCR5Δ24 in different cohorts and its impact on CCR5 expression and HIV‐1 infection in vitro.MethodsWe screened hCCR5Δ24 in a total of 3232 individuals which were either HIV‐1 uninfected, high‐risk HIV‐1 seronegative and seropositive partners from serodiscordant couples, Long‐Term Survivors, or HIV‐1 infected volunteers from Africa (Rwanda, Kenya, Guinea‐Conakry) and Luxembourg, using a real‐time PCR assay. The role of the 24‐base pair deletion on CCR5 expression and HIV infection was assessed in cell lines and PBMC using mRNA quantification, confocal analysis, flow and imaging cytometry.Results and DiscussionAmong the 1661 patients from Rwanda, 12 individuals were heterozygous for hCCR5Δ24 but none were homozygous. Although heterozygosity for this allele may not confer complete resistance to HIV‐1 infection, the prevalence of the mutation was 2.41% (95%CI: 0.43; 8.37) in 83 Long‐Term Survivors (LTS) and 0.99% (95%CI: 0.45; 2.14) in 613 HIV‐1 exposed seronegative members as compared with 0.35% (95% Cl: 0.06; 1.25) in 579 HIV‐1 seropositive members. The prevalence of hCCR5Δ24 was 0.55% (95%CI: 0.15; 1.69) in 547 infants from Kenya but the mutation was not detected in 224 infants from Guinea‐Conakry nor in 800 Caucasian individuals from Luxembourg. Expression of hCCR5Δ24 in cell lines and PBMC showed that the hCCR5Δ24 protein is stably expressed but is not transported to the plasma membrane due to a conformational change. Instead, the mutant receptor was retained intracellularly, colocalized with an endoplasmic reticulum marker and did not mediate HIV‐1 infection. Co‐transfection of hCCR5Δ24 and wtCCR5 did not indicate a transdominant negative effect of CCR5Δ24 on wtCCR5.ConclusionsOur findings indicate that hCCR5Δ24 is not expressed at the cell surface. This could explain the higher prevalence of the heterozygous hCCR5Δ24 in LTS and HIV‐1 exposed seronegative members from serodiscordant couples. Our data suggest an East‐African localization of this deletion, which needs to be confirmed in larger cohorts from African and non‐African countries.

From its capacity for deploying joint operations in conflict zones to its status as a standard-bearing forum for international behaviour, the United Nations has asserted its relevance in a diverse array of issues and conflicts around the world. Equally as diverse has been the scholarship surrounding the United Nations over the past several decades. This collection of essays provides a snapshot of these diverse lines of scholarship, highlighting existing scholarship on a range of topics, as well as identifying areas of opportunity for future scholarly work on these topics. Taken as a whole, this forum more broadly provides insight into core pillars of the United Nations' mission--including the maintenance of peace and security; fostering friendly relations between nations; promoting human rights and humanitarian goals; and encouraging cooperation and harmonization of interests between nations. Moving forward, it is our hope that this collection will serve as a sprigboard for inspiring future work to both build and expand upon the insights from the past several decades of scholarship on the United Nations.

AbstractIntroductionCouples' voluntary HIV counselling and testing (CVCT) is a high‐impact HIV prevention intervention in Rwanda and Zambia. Our objective was to model the cost‐per‐HIV infection averted by CVCT in six African countries guided by an HIV prevention cascade framework. The HIV prevention cascade as yet to be applied to evaluating CVCT effectiveness or cost‐effectiveness.MethodsWe defined a priority population for CVCT in Africa as heterosexual adults in stable couples. Based on our previous experience nationalizing CVCT in Rwanda and scaling‐up CVCT in 73 clinics in Zambia, we estimated HIV prevention cascade domains of motivation for use, access and effectiveness of CVCT as model parameters. Costs‐per‐couple tested were also estimated based on our previous studies. We used these parameters as well as country‐specific inputs to model the impact of CVCT over a five‐year time horizon in a previously developed and tested deterministic compartmental model. We consider six countries across Africa with varied HIV epidemics (South Africa, Zimbabwe, Kenya, Tanzania, Ivory Coast and Sierra Leone). Outcomes of interest were the proportion of HIV infections averted by CVCT, nationwide CVCT implementation costs and costs‐per‐HIV infection averted by CVCT. We applied 3%/year discounting to costs and outcomes. Univariate and Monte Carlo multivariate sensitivity analyses were conducted.ResultsWe estimated that CVCT could avert between 54% (Sierra Leone) and 62% (South Africa) of adult HIV infections. Average costs‐per‐HIV infection averted were lowest in Zimbabwe ($550) and highest in South Africa ($1272). Nationwide implementations would cost between 7% (Kenya) and 21% (Ivory Coast) of a country's President's Emergency Plan for AIDS Relief (PEPFAR) budget over five years. In sensitivity analyses, model outputs were most sensitive to estimates of cost‐per‐couple tested; the proportion of adults in heterosexual couples and HIV prevention cascade domains of CVCT motivation and access.ConclusionsOur model indicates that nationalized CVCT could prevent over half of adult HIV infections for 7% to 21% of the modelled countries' five‐year PEPFAR budgets. While other studies have indicated that CVCT motivation is high given locally relevant promotional and educational efforts, without required indicators, targets and dedicated budgets, access remains low.

BackgroundMany HIV voluntary testing and counselling centres in Africa use rapid antibody tests, in parallel or in sequence, to establish same‐day HIV status. The interpretation of indeterminate or discrepant results between different rapid tests on one sample poses a challenge. We investigated the use of an algorithm using three serial rapid HIV tests in cohabiting couples to resolve unclear serostatuses.MethodsHeterosexual couples visited the Rwanda Zambia HIV Research Group testing centres in Kigali, Rwanda, and Lusaka, Zambia, to assess HIV infection status. Individuals with unclear HIV rapid antibody test results (indeterminate) or discrepant results were asked to return for repeat testing to resolve HIV status. If either partner of a couple tested positive or indeterminate with the screening test, both partners were tested with a confirmatory test. Individuals with indeterminate or discrepant results were further tested with a tie‐breaker and monthly retesting. HIV‐RNA viral load was determined when HIV status was not resolved by follow‐up rapid testing. Individuals were classified based on two of three initial tests as "Positive", "Negative" or "Other". Follow‐up testing and/or HIV‐RNA viral load testing determined them as "Infected", "Uninfected" or "Unresolved".ResultsOf 45,820 individuals tested as couples, 2.3% (4.1% of couples) had at least one discrepant or indeterminate rapid result. A total of 65% of those individuals had follow‐up testing and of those individuals initially classified as "Negative" by three initial rapid tests, less than 1% were resolved as "Infected". In contrast, of those individuals with at least one discrepant or indeterminate result who were initially classified as "Positive", only 46% were resolved as "Infected", while the remainder was resolved as "Uninfected" (46%) or "Unresolved" (8%). A positive HIV serostatus of one of the partners was a strong predictor of infection in the other partner as 48% of individuals who resolved as "Infected" had an HIV‐infected spouse.ConclusionsIn more than 45,000 individuals counselled and tested as couples, only 5% of individuals with indeterminate or discrepant rapid HIV test results were HIV infected. This represented only 0.1% of all individuals tested. Thus, algorithms using screening, confirmatory and tie‐breaker rapid tests are reliable with two of three tests negative, but not when two of three tests are positive. False positive antibody tests may persist. HIV‐positive partner serostatus should prompt repeat testing.

AbstractIntroductionGiven intersecting biological, network and structural risks, men who have sex with men (MSM) and transgender women (TGW) consistently have a high burden of HIV. Although MSM are a key population in Rwanda, there are limited epidemiologic data to guide programming. This study aimed to characterize HIV prevalence and care cascade among MSM and TGW in Kigali.MethodsMSM and TGW ≥ 18 years were recruited using respondent‐driven sampling (RDS) from March–August 2018 in Kigali. Participants underwent a structured interview including measures of individual, network and structural determinants. HIV and sexually transmitted infections (STI) including syphilis, Neisseria gonorrhoea (NG) and Chlamydia trachomatis (CT) were tested. Viral load was measured for MSM living with HIV. Robust Poisson regression was used to characterize the determinants of HIV infection and engagement in the HIV treatment cascade.ResultsA total of 736 participants were enrolled. The mean age was 27 years (range:18 to 68) and 14% (106) were TGW. HIV prevalence was 10% (RDS‐adjusted: 9.2% (95% CI: 6.4 to 12.1)). Unadjusted prevalence of any STI was 20% (147); syphilis: 5.7% (42); CT: 9.1% (67) and NG: 8.8% (65). Anticipated (41%), perceived (36%) and enacted stigmas (45%) were common and higher among TGW (p < 0.001). In multivariable RDS adjusted analysis, higher age (aPR: 1.08 (95% CI: 1.05 to 1.12)) and ever having sex with women (aPR: 3.39 (95% CI: 1.31 to 8.72)) were positively associated with prevalent HIV. Being circumcised (aPR: 0.52 (95% CI: 0.28 to 0.9)) was negatively associated with prevalent HIV infection.Overall, 61% (45/74) of respondents reported knowing their HIV‐positive status. Among these, 98% (44/45) reported antiretroviral therapy use (ART); 75% (33/44) were virally suppressed using a cut‐off of <200 copies/mL. Of the 29 participants who did not report any previous HIV diagnosis or ART use, 38% (11/29) were virally suppressed. Cumulatively, 59% (44/74) of all participants living with HIV were virally suppressed.ConclusionsThese data show a high burden of HIV among MSM/TGW in Kigali, Rwanda. Bisexual concurrency was common and associated with prevalent HIV infection, demonstrating the need of comprehensive screening for all sexual practices and preferences in the provision of comprehensive HIV prevention services in Rwanda. Viral suppression was below the UNAIDS target suggesting poor adherence and potential ART resistance. There is a need for adherence support, screening for primary and secondary ART resistance and stigma mitigation interventions to optimize HIV‐related outcomes for MSM in Rwanda.

Background: The impact and cost-effectiveness of couples' voluntary HIV counselling and testing (CVCT) has not been quantified in real-world settings. We quantify cost-per-HIV-infection averted by CVCT in Zambia from the donor's perspective. Methods: From 2010 to 2016, CVCT was established in 73 Zambian government clinics. The cost-per-HIV-infection averted (CHIA) of CVCT was calculated using observed expenditures and effectiveness over longitudinal follow-up. These observed measures parameterized hypothetical 5-year nationwide implementations of: 'CVCT'; 'treatment-as-prevention (TasP) for discordant couples' identified by CVCT; and 'population TasP' for all HIV+ cohabiting persons identified by individual testing. Results: In all, 207 428 couples were tested (US $52/couple). Among discordant couples in which HIV+ partners self-reported antiretroviral therapy (ART), HIV incidence was 8.5/100 person-years before and 1.8/100 person-years after CVCT (79% reduction). Corresponding reductions for non-ART-using discordant and concordant negative couples were 63% and 47%, respectively. CVCT averted an estimated 58% of new infections at US $659 CHIA. In nationwide implementation models, CVCT would prevent 17 times the number of infections vs 'TasP for discordant couples' at 86% of the cost, and nine times the infections vs 'population TasP' at 28% of the cost. Conclusions: CVCT is a cost-effective, feasible prevention strategy in Zambia. We demonstrate the novel, added effectiveness of providing CVCT to ART users, for whom ART use alone only partially mitigated transmission risk. Our results indicate a major policy shift (supporting development of CVCT indicators, budgets and targets) and have clinical implications (suggesting promotion of CVCT in ART clinics as a high-impact prevention strategy).
