BMJ Open 2021 11 (7) e047017 INTRODUCTION: Daily pre-exposure prophylaxis (PrEP) for HIV prevention is highly effective, but not yet widely deployed in sub-Saharan Africa. We describe how Zambia developed PrEP health policy and then successfully implemented national PrEP service delivery. POLICY DEVELOPMENT: Zambia introduced PrEP as a key strategy for HIV prevention in 2016, and established a National PrEP Task Force to lead policy advocacy and development. The Task Force was composed of government representatives, regulatory agencies, international donors, implementation partners and civil society organisations. Following an implementation pilot, PrEP was rolled out nationally using risk-based criteria alongside a national HIV prevention campaign. NATIONAL SCALE-UP: In the first year of implementation, ending September 2018, 3626 persons initiated PrEP. By September 2019, the number of people starting PrEP increased by over sixfold to 23 327 persons at 728 sites across all ten Zambian provinces. In the first 2 years, 26 953 clients initiated PrEP in Zambia, of whom 31% were from key and priority populations. Continuation remains low at 25% and 11% at 6 and 12 months, respectively. LESSONS LEARNT: Risk-based criteria for PrEP ensures access to those most in need of HIV prevention. Healthcare worker training in PrEP service delivery and health needs of key and priority populations is crucial. PrEP expansion into primary healthcare clinics and community education is required to reach full potential. Additional work is needed to understand and address low PrEP continuation. Finally, a task force of key stakeholders can rapidly develop and implement health policy, which may serve as a model for countries seeking to implement PrEP. |

BMC Urol 2020 20 (1) 45 BACKGROUND: Male circumcision confers partial protection against heterosexual HIV acquisition among men. The President's Emergency Plan for AIDS Relief (PEPFAR) has supported > 18,900,000 voluntary medical male circumcisions (VMMC). Glans injuries (GIs) are rare but devastating adverse events (AEs) that can occur during circumcision. To address this issue, PEPFAR has supported multiple interventions in the areas of surveillance, policy, education, training, supply chain, and AE management. METHODS: Since 2015, PEPFAR has conducted surveillance of GIs including rapid investigation by the in-country PEPFAR team. This information is collected on standardized forms, which were reviewed for this analysis. RESULTS: Thirty-six GIs were reported from 2015 to 2018; all patients were < 15 years old (~ 0.7 per 100,000 VMMCs in this age group) with a decreasing annual rate (2015: 0.7 per 100,000 VMMCs; 2018: 0.4 per 100,000 VMMC; p = 0.02). Most (64%) GIs were partial or complete amputations. All amputations among 10-14 year-olds occurred using the forceps-guided (FG) method, as opposed to the dorsal-slit (DS) method, and three GIs among infants occurred using a Mogen clamp. Of 19 attempted amputation repairs, reattached tissue was viable in four (21%) in the short term. In some cases, inadequate DS method training and being overworked, were found. CONCLUSION: Following numerous interventions by PEPFAR and other stakeholders, GIs are decreasing; however, they have not been eliminated and remain a challenge for the VMMC program. Preventing further cases of complete and partial amputation will likely require additional interventions that prevent use of the FG method in young patients and the Mogen clamp in infants. Improving management of GIs is critical to optimizing outcomes. |
Supporting the massive scale-up of antiretroviral therapy: the evolution of PEPFAR-supported treatment facilities in South Africa, 2005-2009
Larson E , O'Bra H , Brown J , Mbengashe T , Klausner JD . BMC Public Health 2012 12 173 BACKGROUND: South Africa has an estimated 1.5 million persons in need of antiretroviral therapy (ART). In 2004, the South African government began collaborating with the United States President's Emergency Plan for AIDS Relief (PEPFAR) to increase access to ART. We determined how PEPFAR treatment support changed from 2005-2009. METHODS: In order to describe the change in number and type of PEPFAR-supported ART facilities, we analyzed routinely collected program-monitoring data from 2005-2009. The collected data included the number, type and province of facilities as well as the number of patients receiving ART at each facility. RESULTS: The number of PEPFAR-supported facilities providing ART increased from 184 facilities in 2005 to 1,469 facilities in 2009. From 2005-2009 the number of PEPFAR-supported government facilities increased 10.1 fold from 54 to 546 while the number of PEPFAR-supported NGO facilities (including general practitioner and NGO facilities) increased 6.2 fold from 114 to 708. In 2009 the total number of persons treated at PEPFAR-supported NGO facilities was 43,577 versus 501,089 persons at PEPFAR-supported government facilities. Overall, the median number of patients receiving ART per site increased from 81 in 2005 to 136 in 2009. CONCLUSIONS: To mitigate the gap between those needing and those receiving ART, more facilities were supported. The proportion of government facilities supported and the median number of persons treated at these facilities increased. This shift could potentially be sustainable as government sites reach more individuals and receive government funding. These results demonstrate that PEPFAR was able to support a massive scale-up of ART services in a short period of time. |
Scale-up and continuation of antiretroviral therapy in South African treatment programs, 2005-2009
Klausner JD , Serenata C , O'Bra H , Mattson CL , Brown J , Wilson M , Mbengashe T , Goldman TM . J Acquir Immune Defic Syndr 2011 56 (3) 292-5 BACKGROUND: South Africa has the greatest burden of HIV-infection in the world with about 5.2 million HIV-infected adults. In 2003, the South African Government launched a comprehensive HIV and AIDS care treatment program supported by the United States in 2004 through the President's Emergency Plan for AIDS Relief (PEPFAR). METHODS: To describe the scale-up and continuation of antiretroviral therapy in South African Government and PEPFAR-supported sites in South Africa, we conducted a retrospective analysis of routinely collected program reporting data, 2005-2009. RESULTS: From 2005 through 2009, the average rate of persons initiated on antiretroviral therapy in PEPFAR-supported South African Government treatment programs increased nearly four-fold from 6,327 a month in 2005-2006 to 24,622 a month in 2008-2009 resulting in an increase from 33,543 patients on continued treatment in April-June 2005 to 631,985 patients in July-September 2009. Of those 631,985 patients receiving treatment, 65% were women. Men were more likely to be lost to follow-up (9.2% vs. 7.8%, PR 1.18, 95% CI 1.17-1.19) and more likely to die (5.6% vs. 4.1%, PR 1.36, 95% CI 1.35-1.37) than women. CONCLUSIONS: Scale-up and continuation of antiretroviral therapy in South Africa has been a remarkable medical accomplishment. Because more women receive and continue treatment, more efforts are needed to treat and retain men. |
The associations of voluntary counseling and testing acceptance and the perceived likelihood of being HIV-infected among men with multiple sex partners in a South African township
Johnston L , O'Bra H , Chopra M , Mathews C , Townsend L , Sabin K , Tomlinson M , Kendall C . AIDS Behav 2010 14 (4) 922-31 This paper examines the socio-demographic factors and sexual risk behaviors (condom use, number of sexual partners, STI symptoms) associated with voluntary counselling and testing (VCT) acceptance and self-perceived risk of being HIV-infected among black men with multiple and younger sex partners in a South African township outside of Cape Town. Using respondent driven sampling, we interviewed 421 men, of whom 409 (97.3%) consented to provide a dried blood spot, 12.3% were HIVinfected (95% confidence intervals [CI.] 8.3, 16.9) and 47.2% (CI. 41.1, 53.6) accepted on site VCT. Twenty six percent (CI. 20.2, 30.7) reported having an HIV test in the past year. Few men perceived themselves as very likely to be infected with HIV (15.6%; CI. 10.4, 20.5). VCT acceptance was significantly associated with being older, married or living with a partner, having higher education, having four to six partners in the past three months and testing HIV positive. Self-perceived likelihood of being HIV infected was significantly associated with low condom use and having seven or more partners in the past three months, and testing HIV positive. These findings indicate that men correctly understand that engaging in certain HIV risk behaviors increases the likelihood of HIV-infection. However, those who perceive themselves at high risk of having HIV do not seek testing. Further investigation into the psychological and cultural barriers to reducing risky sexual behaviors and accessing VCT and other HIV services is recommended. |
