RESUMEN

BACKGROUND: To quantify the impact of the US President's Emergency Plan for AIDS Relief (PEPFAR) on the risk of HIV transmission through infected blood donations in countries supported by PEPFAR blood safety programs. METHODS: Data reported to the World Health Organization Global Database on Blood Safety were analyzed from 28 countries in sub-Saharan Africa (SSA), Asia, and the Caribbean during 2004-2015. We used the Goals model of Spectrum Spectrum System Software, version 5.53, to perform the modeling, assuming laboratory quality for HIV testing had 91.9% sensitivity and 97.7% specificity irrespective of testing method based on results of two external quality assurance and proficiency testing studies of transfusion screening for HIV in SSA blood centers. We calculated the number of new HIV infections from the number of transfusions and the prevalence of HIV infection acquired from blood transfusions with infected blood donations. We determined the impact of laboratory testing programs by estimating the number of new HIV infections averted since PEPFAR implementation. RESULTS: Assuming that HIV testing would not be performed in any of these countries without PEPFAR funding, the number of new HIV infections acquired from blood transfusions averted by laboratory testing increased over time in all 28 countries. The total number of HIV infections averted was estimated at 229 278 out of 20 428 373 blood transfusions during 2004-2015. CONCLUSION: Our mathematical modeling suggests a positive impact achieved over 12 years of PEPFAR support for blood safety. Standardized HIV testing of donated blood has reduced the risk of HIV transmission through blood transfusions in SSA, Asia, and the Caribbean.

RESUMEN

OBJECTIVE: While the Global Database on Blood Safety (GDBS) helps to monitor the status of adequate and safe blood availability, its presence alone does not serve as a solution to existing challenges. The objective of this evaluation was to determine the GDBS usefulness in improving the availability of adequate safe blood and its ability to function as a surveillance system. METHODS: The GDBS was evaluated using methods set out by the Centers for Disease Control and Prevention (CDC) Guidelines for assessing surveillance systems. Six recommended tasks were used to evaluate if the GDBS met the requirements of a surveillance system in a public health context. RESULTS: The majority of stakeholders engaged with GDBS found it was unique and useful. The GDBS answered all six questions essential for determining a blood safety surveillance system's usefulness. The GDBS fully met the needs to six of the eleven attributes used for evaluating the usefulness of a surveillance system. CONCLUSION: The GDBS is a unique global activity that provides vital data on safety of blood transfusion services across countries and regions. However, aspects of the GDBS such as timeliness of reporting and improvement of WHO Member States national blood information systems could enhance its effectiveness and potential to serve as a global surveillance system for blood safety.

RESUMEN

Male circumcision (MC) is a key HIV prevention intervention for men in countries with high HIV prevalence. Women's understanding of MC is important but poorly understood. We conducted a systematic review including women's knowledge of MC's biomedical impacts and its association with female sexual satisfaction and function through October 2017. Thirty-eight articles were identified: thirty-two with knowledge outcomes, seven with sexual satisfaction, and four with sexual function (N = 38). Respondent proportions aware MC protects men from HIV were 9.84-91.8% (median 60.0%). Proportions aware MC protects men from STIs were 14.3-100% (72.6%). Proportions aware MC partially protects men from HIV were 37.5-82% (50.7%). Proportions aware MC is not proven to protect women from infection by an HIV-positive partner were 90.0-96.8% (93.0%). No increases over time were noted. Women's MC knowledge is variable. Education could help women support MC and make better-informed sexual decisions.

RESUMEN

Ensuring availability of safe blood products through recruitment of voluntary, nonremunerated, blood donors (VNRDs) and prevention of transfusion-transmissible infections (TTIs), including human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis, is important for public health (1,2). During 2004-2016, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) provided approximately $468 million in financial support and technical assistance* to 14 sub-Saharan African countries† with high HIV prevalence to strengthen national blood transfusion services (NBTSs)§ and improve blood safety and availability. CDC analyzed these countries' 2014-2016 blood safety surveillance data to update previous reports (1,2) and summarize achievements and programmatic gaps as some NBTSs begin to transition funding and technical support from PEPFAR to local ministries of health (MOHs) (2,3). Despite a 60% increase in blood supply since 2004 and steady declines in HIV prevalence (to <1% among blood donors in seven of the 14 countries), HIV prevalence among blood donors still remains higher than that recommended by the World Health Organization (WHO) (4). PEPFAR support has contributed to significant reductions in HIV prevalence among blood donors in the majority of PEPFAR-supported countries, and linking donors who screen HIV-positive to confirmatory testing and indicated treatment, as well as further reducing TTIs, remains a public health priority (5).

RESUMEN

Male circumcision reduces the risk for female-to-male human immunodeficiency virus (HIV) transmission by approximately 60% (1) and has become a key component of global HIV prevention programs in countries in Eastern and Southern Africa where HIV prevalence is high and circumcision coverage is low. Through September 2017, the President's Emergency Plan for AIDS Relief (PEPFAR) had supported 15.2 million voluntary medical male circumcisions (VMMCs) in 14 priority countries in Eastern and Southern Africa (2). Like any surgical intervention, VMMC carries a risk for complications or adverse events. Adverse events during circumcision of males aged ≥10 years occur in 0.5% to 8% of procedures, though the majority of adverse events are mild (3,4). To monitor safety and service quality, PEPFAR tracks and reports qualifying notifiable adverse events. Data reported from eight country VMMC programs during 2015-2016 revealed that bleeding resulting in hospitalization for ≥3 days was the most commonly reported qualifying adverse event. In several cases, the bleeding adverse event revealed a previously undiagnosed or undisclosed bleeding disorder. Bleeding adverse events in men with potential bleeding disorders are serious and can be fatal. Strategies to improve precircumcision screening and performance of circumcisions on clients at risk in settings where blood products are available are recommended to reduce the occurrence of these adverse events or mitigate their effects (5).

RESUMEN

BACKGROUND: Male circumcision provides men with approximately 60% protection from acquiring HIV infection via heterosexual sex, and has become a key component of HIV prevention efforts in sub-Saharan Africa. Possible mechanisms for this protection include removal of the inflammatory anaerobic sub-preputial environment and the high concentration of Langerhans cells on the inside of the foreskin, both believed to promote local vulnerability to HIV infection. In people who do acquire HIV, viral load is partially determined by infecting partner viral load, potentially mediated by size of infecting inoculum. By removing a portal for virion entry, prior male circumcision could decrease infecting inoculum and thus viral load in men who become HIV-infected, conferring the known associated benefits of slower progression to disease and decreased infectiousness. METHODS: We performed an as-treated analysis of plasma samples collected under a randomized controlled trial of male circumcision for HIV prevention, comparing men based on their circumcision status at the time of HIV acquisition, to determine whether circumcision is associated with lower viral load. Eligible men were seroconverters who had at least one plasma sample available drawn at least 6 months after infection, reported no potential exposures other than vaginal sex and, for those who were circumcised, were infected more than 6 weeks after circumcision, to eliminate the open wound as a confounder. Initial viral load testing indicated that quality of pre-2007 samples might have been compromised during storage and they were excluded, as were those with undetectable or unquantifiable results. Log viral loads were compared between groups using univariable and multivariable linear regression, adjusting for sample age and sexually transmitted infection diagnosis with 3.5 months of seroconversion, with a random effect for intra-individual clustering for samples from the same man. A per-protocol analysis was also performed. RESULTS: There were no viral load differences between men who were circumcised and uncircumcised at the time of HIV infection (means 4.00 and 4.03 log10 copies/mL respectively, p = .88) in any analysis. CONCLUSION: Circumcision status at the time of HIV infection does not affect viral load in men. TRIAL REGISTRATION: The original RCT which provided the samples was ClinicalTrials.gov trial NCT00059371 .

RESUMEN

BACKGROUND: The burden of sexually transmitted infections (STIs) has been increasing in Kenya, as is the case elsewhere in sub-Saharan Africa, while measures for control and prevention are weak. The objectives of this study were to (1) describe healthcare provider (HCP) knowledge and practices, (2) explore HCP attitudes and beliefs, (3) identify structural and environmental factors affecting STI management, and (4) seek recommendations to improve the STI program in Kenya. METHODS AND FINDINGS: Using individual in-depth interviews (IDIs), data were obtained from 87 HCPs working in 21 high-volume comprehensive HIV care centers (CCCs) in 7 of Kenya's 8 regions. Transcript coding was performed through an inductive and iterative process, and the data were analyzed using NVivo 10.0. Overall, HCPs were knowledgeable about STIs, saw STIs as a priority, reported high STI co-infection amongst people living with HIV (PLHIV), and believed STIs in PLHIV facilitate HIV transmission. Most used the syndromic approach for STI management. Condoms and counseling were available in most of the clinics. HCPs believed that having an STI increased stigma in the community, that there was STI antimicrobial drug resistance, and that STIs were not prioritized by the authorities. HCPs had positive attitudes toward managing STIs, but were uncomfortable discussing sexual issues with patients in general, and profoundly for anal sex. The main barriers to the management of STIs reported were low commitment by higher levels of management, few recent STI-focused trainings, high stigma and low community participation, and STI drug stock-outs. Solutions recommended by HCPs included formulation of new STI policies that would increase access, availability, and quality of STI services; integrated STI/HIV management; improved STI training; increased supervision; standardized reporting; and community involvement in STI prevention. The key limitations of our study were that (1) participant experience and how much of their workload was devoted to managing STIs was not considered, (2) some responses may have been subject to recall and social desirability bias, and (3) patients or clients of STI services were not interviewed, and therefore their inputs were not obtained. While considering these limitations, the number and variety of facilities sampled, the mix of staff cadres interviewed, the use of a standardized instrument, and the consistency of responses add strength to our findings. CONCLUSIONS: This study showed that HCPs understood the challenges of, and solutions for, improving the management of STIs in Kenya. Commitment by higher management, training in the management of STIs, measures for reducing stigma, and introducing new policies of STI management should be considered by health authorities in Kenya.

RESUMEN

BACKGROUND: Identifying and treating genital infections, including sexually transmitted infections (STI), among newly diagnosed human immunodeficiency virus (HIV)-infected individuals may benefit both public and individual health. We assessed prevalence of genital infections and their correlates among newly diagnosed HIV-infected individuals enrolling in HIV care services in Namibia. METHODS: Newly diagnosed HIV-infected adults entering HIV care at 2 health facilities in Windhoek, Namibia, were recruited from December 2012 to March 2014. Participants provided behavioral and clinical data including CD4+ T lymphocyte counts. Genital and blood specimens were tested for gonorrhea, Chlamydia, trichomoniasis, Mycoplasma genitalium, syphilis, bacterial vaginosis, and vulvovaginal candidiasis. RESULTS: Among 599 adults, 56% were women and 15% reported consistent use of condoms in the past 6 months. The most common infections were bacterial vaginosis (37.2%), trichomoniasis (34.6%) and Chlamydia (14.6%) in women and M. genitalium (11.4%) in men. Correlates for trichomoniasis included being female (adjusted relative risk, [aRR], 7.18; 95% confidence interval [CI], 4.07-12.65), higher education (aRR, 0.58; 95% CI, 0.38-0.89), and lower CD4 cell count (aRR, 1.61; 95% CI, 1.08-2.40). Being female (aRR, 2.39; 95% CI, 1.27-4.50), nonmarried (aRR, 2.30; (95% CI, 1.28-4.14), and having condomless sex (aRR, 2.72; 95% CI, 1.06-7.00) were independently associated with chlamydial infection. Across all infections, female (aRR, 2.31; 95% CI, 1.79-2.98), nonmarried participants (aRR, 1.29; 95% CI, 1.06-1.59), had higher risk to present with any STI, whereas pregnant women (aRR, 1.16, 95% CI 1.03-1.31) were at increased risk of any STI or reproductive tract infection.

RESUMEN

Voluntary medical male circumcision (VMMC) decreases the risk for female-to-male HIV transmission by approximately 60%, and the President's Emergency Plan for AIDS Relief (PEPFAR) is supporting the scale-up of VMMC for adolescent and adult males in countries with high prevalence of human immunodeficiency virus (HIV) and low coverage of male circumcision. As of September 2015, PEPFAR has supported approximately 8.9 million VMMCs.

RESUMEN

BACKGROUND: Namibia's HIV prevalence is 13.3%. Alcohol is associated with sexual risk-taking, leading to increased HIV risk. Baseline sexual behaviors, HIV and alcohol knowledge, and self-perceived HIV risk were examined among men reporting high-risk drinking in Katutura, Namibia. METHODS: HIV negative men, ≥ 18 years, were screened for harmful or hazardous levels of drinking and >1 recent sex partner prior to randomization into control or intervention arm. SAS 9.3 and R 3.01 were used for descriptive baseline cohort analyses. RESULTS: A total of 501 participants who met criteria were included in analysis (mean Alcohol Use Disorders Identification Test [AUDIT] =12.4). HIV and alcohol knowledge were high with the majority (>85 and 89.8-98%, respectively) of respondents correctly answering assessment questions. Despite high knowledge levels, 66.7% of men felt they were at some or high risk of HIV acquisition. Among those respondents, 56.5% stated often wanting to have sex after drinking and 40.3% stated sex was better when drunk. Among respondents with non-steady partners [n = 188], 44.1% of last sexual encounters occurred while the participant was drunk and condoms were not used 32.5% of those times. Among persons who were not drunk condoms were not used 13.3% of those times. CONCLUSIONS: Sex with casual partners was high. Inconsistent condom use and alcohol use before sex were frequently reported. Increased emphasis on alcohol risk-reduction strategies, including drinking due to peer pressure and unsafe sexual behaviors, is needed.

RESUMEN

Fourth-generation HIV rapid tests (RTs) claim to detect both p24 antigen (Ag) and HIV antibodies (Ab) for early identification of acute infections, important for targeting prevention and reducing HIV transmission. In a nationally representative household survey in Swaziland, 18,172 adults, age 18 to 49 years, received home-based HIV rapid testing in 2010 and 2011. Of the 18,172 individuals, 5,822 (32.0%) were Ab positive (Ab(+)) by the Determine HIV-1/2 Ab/Ab combo test, and 5,789 (99.4%) of those were confirmed to be reactive in the Uni-Gold test. Determine combo identified 12 individuals as having acute infections (Ag(+)/Ab negative [Ab(-)]); however, none had detectable HIV-1 RNA and 8 of 12 remained HIV negative at their 6-week follow-up visit (4 were lost to follow-up). All RT-nonreactive samples were pooled and tested by nucleic acid amplification testing (NAAT) to identify acute infections. NAAT identified 13 (0.1%) of the 12,338 HIV antibody-negative specimens as HIV RNA positive, with RNA levels ranging from 300 to >10,000,000 copies/ml. However, none of them were Ag(+) by Determine combo. Follow-up testing of 12 of the 13 NAAT-positive individuals at 6 months demonstrated 12 seroconversions (1 individual was lost to follow-up). Therefore, the Determine combo test had a sensitivity of 0% (95% confidence interval, 0 to 28) and positive predictive value of 0% for the detection of acute infections. The ability of the 4th-generation Determine combo to detect antigen was very poor in Swaziland. Thus, the Determine combo test does not add any value to the current testing algorithm; rather, it adds additional costs and complexity to HIV diagnosis. The detection of acute HIV infections may need to rely on other testing strategies.

RESUMEN

BACKGROUND: Voluntary medical male circumcision (VMMC) reduces HIV acquisition among heterosexual men by approximately 60%. VMMC is a surgical procedure and some adverse events (AEs) are expected. Swaziland's Ministry of Health established a toll-free hotline to provide general information about VMMC and to manage post-operative clinical AEs through telephone triage. METHODS: We retrospectively analyzed a dataset of telephone calls logged by the VMMC hotline during a VMMC campaign. The objectives were to determine reasons clients called the VMMC hotline and to ascertain the accuracy of telephone-based triage for VMMC AEs. We then analyzed VMMC service delivery data that included date of surgery, AE type and severity, as diagnosed by a VMMC clinician as part of routine post-operative follow-up. Both datasets were de-identified and did not contain any personal identifiers. Proportions of AEs were calculated from the call data and from VMMC service delivery data recorded by health facilities. Sensitivity analyses were performed to assess the accuracy of phone-based triage compared to clinically confirmed AEs. RESULTS: A total of 17,059 calls were registered by the triage nurses from April to December 2011. Calls requesting VMMC education and counseling totaled 12,492 (73.2%) and were most common. Triage nurses diagnosed 384 clients with 420 (2.5%) AEs. According to the predefined clinical algorithms, all moderate and severe AEs (153) diagnosed through telephone-triage were referred for clinical management at a health facility. Clinicians at the VMMC sites diagnosed 341 (4.1%) total clients as having a mild (46.0%), moderate (47.8%), or severe (6.2%) AE. Eighty-nine (26%) of the 341 clients who were diagnosed with AEs by clinicians at a VMMC site had initially called the VMMC hotline. The telephone-based triage system had a sensitivity of 69%, a positive predictive value of 83%, and a negative predictive value of 48% for screening moderate or severe AEs of all the AEs. CONCLUSIONS: The use of a telephone-based triage system may be an appropriate first step to identify life-threatening and urgent complications following VMMC surgery.

RESUMEN

BACKGROUND: Identifying sexually transmitted infections (STI) in HIV-infected individuals has potential to benefit individual and public health. There are few guidelines regarding routine STI screening in sub-Saharan African HIV programs. We determined sexual risk behavior and prevalence and correlates of STI in a national survey of large HIV treatment programs in Kenya. METHODS: A mobile screening team visited 39 (95%) of the 42 largest HIV care programs in Kenya and enrolled participants using population-proportionate systematic sampling. Participants provided behavioral and clinical data. Genital and blood specimens were tested for trichomoniasis, gonorrhea, chlamydia, syphilis, and CD4 T-lymphocyte counts. RESULTS: Among 1661 adults, 41% reported no sexual partners in the past 3 months. Among those who reported sex in the past 3 months, 63% of women reported condom use during this encounter compared with 77% of men (P < 0.001). Trichomoniasis was the most common STI in women (10.9%) and men (2.8%); prevalences of gonorrhea, chlamydia, and syphilis were low (<1%-2%). Among women, younger age (adjusted odds ratio [OR], 0.96 per year; 95% confidence interval [CI], 0.94-0.98) and primary school education or lower level (adjusted OR, 2.16; 95% CI, 1.37-3.40) were independently associated with trichomoniasis, whereas CD4 count, cotrimoxazole use, and reported condom use were not. Reported condom use at last sex was associated with reporting that the clinic provided condoms among both women (OR, 1.7; 95% CI, 1.17-2.35) and men (OR, 2.4; 95% CI, 1.18-4.82). CONCLUSIONS: Women attending Kenyan HIV care programs had a 10.9% prevalence of trichomoniasis, suggesting that screening for this infection may be useful. Condom provision at clinics may enhance secondary HIV prevention efforts.

RESUMEN

INTRODUCTION: Voluntary medical male circumcision (VMMC) for HIV prevention began in Nyanza Region, Kenya in 2008. By 2014, approximately 800,000 VMMCs had been conducted, and 84.9% were among males aged 15-24 years. We evaluated the impact of interpersonal communication (IPC) and dedicated service outlets (DSO) on VMMC uptake among men aged 25-39 years in Nyanza Region. MATERIALS AND METHODS: We conducted a cluster randomized controlled trial in 45 administrative Locations (clusters) in Nyanza Region between May 2014 and June 2016 among uncircumcised men aged 25-34 years. In arm one, an IPC toolkit was used to address barriers to VMMC. In the second arm, men were referred to DSO that were modified to address their preferences. Arm three combined the IPC and DSO arms, and arm four was standard of care (SOC). Randomization was done at Location level (11-12 per arm). The primary outcome was the proportion of enrolled men who received VMMC within three months. Generalized estimating equations were used to evaluate the effect of interventions on the outcome. RESULTS: At baseline, 9,238 households with men aged 25-39 years were enumerated, 9,679 men were assessed, and 2,792 (28.8%) were eligible. For enrollment, 577 enrolled in the IPC arm, 825 in DSO, 723 in combined IPC + DSO, and 667 in SOC. VMMC uptake among men in the SOC arm was 3.2%. In IPC, DSO, and combined IPC + DSO arms, uptake was 3.3%, 4.5%, and 4.4%, respectively. The adjusted odds ratio (aOR) of VMMC uptake in the study arms compared to SOC were IPC aOR = 1.03; 95% CI: 0.50-2.13, DSO aOR = 1.31; 95% CI: 0.67-2.57, and IPC + DSO combined aOR = 1.31, 95% CI: 0.65-2.67. DISCUSSION: Using these interventions among men aged 25-39 years did not significantly impact VMMC uptake. These findings suggest that alternative demand creation strategies for VMMC services are needed to reach men aged 25-39 years. TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT02497989.

RESUMEN

INTRODUCTION: Voluntary medical male circumcision (VMMC) uptake has been slow in some countries, including Botswana. To inform demand creation efforts, we examined sociodemographic characteristics and referral procedures associated with VMMC uptake in the Botswana Combination Prevention Project (BCPP) and examined the effectiveness of referral of men to MC services from HIV testing venues. DESIGN: BCPP was a community-randomized trial evaluating the impact of a combination HIV prevention package which included VMMC on community HIV incidence. We conducted a sub-analysis of VMMC uptake in intervention communities. METHODS: During the initial VMMC campaign in 15 intervention communities, baseline male circumcision (MC) status was assessed among men eligible for HIV testing. Uncircumcised male community residents aged 16-49 years with negative/unknown HIV status were mobilized and linked to study VMMC services. Outcomes included MC baseline status and uptake through study services. Univariate and multivariate logistic regressions were performed to identify factors associated with MC uptake. RESULTS: Of 12,864 men eligible for testing, 50% (n = 6,448) were already circumcised. Among the uncircumcised men (n = 6,416), 10% (n = 635) underwent MC. Of the 5,071 men identified as eligible for MC through HIV testing services, 78% declined referral and less than 1% of those were circumcised. Of those accepting referral (n = 1,107), 16% were circumcised. Younger (16-24 years) (aOR: 1.51; 95%CI:1.22,1.85), unemployed men (aOR:1.34; 95%CI: 1.06,1.69), and those undergoing HIV testing at mobile venues (aOR: 1.88; 95%CI: 1.53,2.31) were more likely to get circumcised. Fear of pain was the most prevalent (27%) reason given for not being circumcised. CONCLUSION: Younger, unemployed men seeking HIV testing at mobile sites in Botswana were more likely to get VMMC. Addressing unique barriers for employed and older men may be necessary. Given the simplicity of VMMC as an intervention, the HIV testing programs offer a platform for identifying uncircumcised men and offering information and encouragement to access services.

RESUMEN

Voluntary medical male circumcision (VMMC) reduces female-to-male HIV transmission by approximately 60%; modeling suggests that scaling up VMMC to 80% of men 15- to 49-years-old within five years would avert over 3.3 million new HIV infections in 14 high priority countries/regions in southern and eastern Africa by 2025 and would require 20.33 million circumcisions. However, the shortage of health professionals in these countries must be addressed to reach these proposed coverage levels. To identify human resource approaches that are being used to improve VMMC volume and efficiency, we looked at previous literature and conducted a program review. We identified surgical efficiencies, non-surgical efficiencies, task shifting, task sharing, temporary redeployment of public sector staff during VMMC campaign periods, expansion of the health workforce through recruitment of unemployed, recently retired, newly graduating, or on-leave health care workers, and the use of volunteer medical staff from other countries as approaches that address human resource constraints. Case studies from Kenya, Tanzania, and Swaziland illustrate several innovative responses to human resource challenges. Although the shortage of skilled personnel remains a major challenge to the rapid scale-up of VMMC in the 14 African priority countries/regions, health programs throughout the region may be able to replicate or adapt these approaches to scale up VMMC for public health impact.

RESUMEN

Since the World Health Organization and the Joint United Nations Programme on HIV/AIDS recommended implementation of medical male circumcision (MC) as part of HIV prevention in areas with low MC and high HIV prevalence rates in 2007, the government of Kenya has developed a strategy to circumcise 80% of uncircumcised men within five years. To facilitate the quick translation of research to practice, a national MC task force was formed in 2007, a medical MC policy was implemented in early 2008, and Nyanza Province, the region with the highest HIV burden and low rates of circumcision, was prioritized for services under the direction of a provincial voluntary medical male circumcision (VMMC) task force. The government's early and continuous engagement with community leaders/elders, politicians, youth, and women's groups has led to the rapid endorsement and acceptance of VMMC. In addition, several innovative approaches have helped to optimize VMMC scale-up. Since October 2008, the Kenyan VMMC program has circumcised approximately 290,000 men, mainly in Nyanza Province, an accomplishment made possible through a combination of governmental leadership, a documented implementation strategy, and the adoption of appropriate and innovative approaches. Kenya's success provides a model for others planning VMMC scale-up programs.

RESUMEN

INTRODUCTION: The scale-up of Universal Test and Treat has resulted in reductions in HIV morbidity, mortality and incidence. However, healthcare system and personal challenges have impacted the levels of treatment coverage achieved. We implemented interventions to improve linkage to care, retention, viral load (VL) coverage and service delivery, and describe the HIV care cascade over the course of the Botswana Combination Prevention Project (BCPP) study. METHODS: BCPP was designed to evaluate the impact of prevention interventions on HIV incidence in 30 communities in Botswana. We followed a longitudinal cohort of newly identified and known HIV-positive persons not on antiretroviral therapy (ART) identified through community-based testing activities through BCPP and referred with appointments to local HIV clinics in 15 intervention communities. Those who did not keep the first or follow-up appointments were tracked and traced through phone and home contacts. Improvements to service delivery models in the intervention clinics were also implemented. RESULTS: A total of 3,657 newly identified or HIV-positive persons not on ART were identified and referred to their local HIV clinic; 90% (3,282/3,657) linked to care and of those, 93% (3,066/3,282) initiated treatment. Near the end of the study, 221 persons remained >90 days late for appointments or missing. Tracing efforts identified 54/3,066 (2%) persons who initiated treatment but died, and 106/3,066 (3%) persons were located and returned to treatment. At study end, 61/3,066 (2%) persons remained missing and were never reached. Overall, 2,951 (98%) persons living with HIV (PLHIV) who initiated treatment were still alive, retained in care and still receiving ART out of the 3,001 persons alive at the end of the study. Of those on ART, 2,854 (97%) had current VL results and 2,784 (98%) of those were virally suppressed at study end. CONCLUSIONS: This study achieved high rates of linkage, treatment initiation, retention and VL coverage and suppression in a cohort of newly identified and known PLHIV not on ART. Tracking and tracing interventions effectively identified those persons who needed more resource intensive follow-up. The interventions implemented to improve service delivery and data quality may have also contributed to high linkage and retention rates. Clinical trial number: NCT01965470.
