Identifying key drivers of the impact of an HIV cure intervention in sub-Saharan Africa
BACKGROUND:  The properties required of an intervention that results in eradication or control of HIV in absence of antiretroviral therapy (ART-free viral suppression) to make it cost-effective in low income settings are unknown. METHODS:  We used a model of HIV and ART to investigate the effect of introducing an ART-free viral suppression intervention in 2022 in an example country of Zimbabwe. We assumed that the intervention (cost: 300 million (8.7% saving). An intervention of this efficacy costing anything up to $1400 is likely to be cost-effective in this setting. CONCLUSION:  Interventions aimed at curing HIV have the potential to improve overall disease burden and to reduce costs. Given the effectiveness and cost of ART, such interventions would have to be inexpensive and highly effective
Implementation of Antiretroviral Therapy for Life in Pregnant/Breastfeeding HIV+ Women (Option B+) Alongside Rollout and Changing Guidelines for ART Initiation in Rural Zimbabwe: The Lablite Project Experience.
BACKGROUND: Lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women (Option B+) was rolled out in Zimbabwe from 2014, with simultaneous raising of the CD4 treatment threshold to 500 cells per cubic millimeter in nonpregnant/breastfeeding adults and children 5 years and over. METHODS: Lablite is an implementation project in Zimbabwe, Malawi, and Uganda evaluating ART rollout. Routine patient-level data were collected for 6 months before and 12 months after Option B+ rollout at a district hospital and 3 primary care facilities in Zimbabwe (2 with outreach ART and 1 with no ART provision before Option B+). RESULTS: Between September 2013 and February 2015, there were 1686 ART initiations in the 4 facilities: 91% adults and 9% children younger than 15 years. In the 3 facilities with established ART, initiations rose from 300 during 6 months before Option B+ to 869 (2.9-fold) and 463 (1.5-fold), respectively, 0-6 months and 6-12 months after Option B+. Post-Option B+, an estimated 43% of pregnant/breastfeeding women needed ART for their own health, based on World Health Organization stage 3/4 or CD4 ≤350 per cubic millimeter (64% for CD4 ≤500). Seventy-four men (22%) and 123 nonpregnant/breastfeeding women (34%) initiated ART with CD4 >350 after the CD4 threshold increase. Estimated 12-month retention on ART was 79% (69%-87%) in Option B+ women (significantly lower in younger women, P = 0.01) versus 93% (91%-95%) in other adults (difference P < 0.001). CONCLUSIONS: There were increased ART initiations in all patient groups after implementation of World Health Organization 2013 guidelines. Retention of Option B+ women was poorer than retention of other adults; younger women require attention because they are more likely to disengage from care
Assessment of the Potential Impact and Cost-effectiveness of Self-Testing for HIV in Low-Income Countries
Patient-level benefits associated with decentralization of antiretroviral therapy services to primary health facilities in Malawi and Uganda
Background The Lablite project captured information on access to antiretroviral therapy (ART) at larger health facilities (‘hubs’) and lower-level health facilities (‘spokes’) in Phalombe district, Malawi and in Kalungu district, Uganda. Methods We conducted a cross-sectional survey among patients who had transferred to a spoke after treatment initiation (Malawi, n=54; Uganda, n=33), patients who initiated treatment at a spoke (Malawi, n=50; Uganda, n=44) and patients receiving treatment at a hub (Malawi, n=44; Uganda, n=46). Results In Malawi, 47% of patients mapped to the two lowest wealth quintiles (Q1–Q2); patients at spokes were poorer than at a hub (57% vs 23% in Q1–Q2; p<0.001). In Uganda, 7% of patients mapped to Q1–Q2; patients at the rural spoke were poorer than at the two peri-urban facilities (15% vs 4% in Q1–Q2; p<0.001). The median travel time one way to a current ART facility was 60 min (IQR 30–120) in Malawi and 30 min (IQR 20–60) in Uganda. Patients who had transferred to the spokes reported a median reduction in travel time of 90 min in Malawi and 30 min in Uganda, with reductions in distance and food costs. Conclusions Decentralizing ART improves access to treatment. Community-level access to treatment should be considered to further minimize costs and time
The Lablite project: A cross-sectional mapping survey of decentralized HIV service provision in Malawi, Uganda and Zimbabwe
Abstract
Background
In sub-Saharan Africa antiretroviral therapy (ART) is being decentralized from tertiary/secondary care facilities to primary care. The Lablite project supports effective decentralization in 3 countries. It began with a cross-sectional survey to describe HIV and ART services.
Methods
81 purposively sampled health facilities in Malawi, Uganda and Zimbabwe were surveyed.
Results
The lowest level primary health centres comprised 16/20, 21/39 and 16/22 facilities included in Malawi, Uganda and Zimbabwe respectively. In Malawi and Uganda most primary health facilities had at least 1 medical assistant/clinical officer, with average 2.5 and 4 nurses/midwives for median catchment populations of 29,275 and 9,000 respectively. Primary health facilities in Zimbabwe were run by nurses/midwives, with average 6 for a median catchment population of 8,616. All primary health facilities provided HIV testing and counselling, 50/53 (94%) cotrimoxazole preventive therapy (CPT), 52/53 (98%) prevention of mother-to-child transmission of HIV (PMTCT) and 30/53 (57%) ART management (1/30 post ART-initiation follow-up only). All secondary and tertiary-level facilities provided HIV and ART services. In total, 58/81 had ART provision. Stock-outs during the 3 months prior to survey occurred across facility levels for HIV test-kits in 55%, 26% and 9% facilities in Malawi, Uganda and Zimbabwe respectively; for CPT in 58%, 32% and 9% and for PMTCT drugs in 26%, 10% and 0% of facilities (excluding facilities where patients were referred out for either drug). Across all countries, in facilities with ART stored on-site, adult ART stock-outs were reported in 3/44 (7%) facilities compared with 10/43 (23%) facility stock-outs of paediatric ART. Laboratory services at primary health facilities were limited: CD4 was used for ART initiation in 4/9, 5/6 and 13/14 in Malawi, Uganda and Zimbabwe respectively, but frequently only in selected patients. Routine viral load monitoring was not used; 6/58 (10%) facilities with ART provision accessed centralised viral loads for selected patients.
Conclusions
Although coverage of HIV testing, PMTCT and cotrimoxazole prophylaxis was high in all countries, decentralization of ART services was variable and incomplete. Challenges of staffing and stock management were evident. Laboratory testing for toxicity and treatment effectiveness monitoring was not available in most primary level facilities
Impact of decentralisation of antiretroviral therapy services on HIV testing and care at a population level in Agago District in rural Northern Uganda : results from the Lablite population surveys
Background: We conducted unlinked cross-sectional population-based surveys in Northern Uganda before and after antiretroviral therapy (ART) provision (including Option B+ [lifelong ART for pregnant/breast-feeding women]) at a local primary care facility (Lira Kato Health Centre [HC]). Prior to decentralisation, people travelled 56-76 km round-trip for ART; we aimed to evaluate changes in uptake of HIV-testing, ART coverage and access to ART following decentralisation. Methods: A total of 2124 adults in 1351 households in two parishes closest to Lira Kato HC were interviewed using questionnaires between March and April 2013 and 2123 adults in 1229 households between January and March 2015. Results: Adults reporting HIV-testing in the last year increased from 1077/2124 (50.7%) to 1298/2123 (61.1%) between surveys (p<0.001). ART coverage increased from 74/136 (54.4%) self-reported HIV-positive adults in 2013 to 108/133 (81.2%) in 2015 (p<0.001). Post-decentralisation, 47/108 (43.5%) of those on ART were in care at Lira Kato HC (including 37 new initiations). Most of the remainder (47/61, 77%) started ART prior to any ART provision at Lira Kato HC; the most common reason given for not accessing ART locally was concern about drug-stock-outs (30/59, 51%). Conclusions: HIV-testing and ART coverage increased after decentralisation combined with Option B+ roll-out. However, patients on ART before decentralisation were reluctant to transfer to their local facility
