UNAIDS 2014 “Ambitious Treatment Targets: Writing the final chapter of the AIDS epidemic” Critical intervention in the response: preventing premature mortality and new infections HIV treatment requires more resources than any other single area of the HIV and AIDS response UNAIDS : 39% of all resources for HIV Exciting time in the discussion on ART: call from UNAIDS: 90% diagnosed, 90% on ART; 90% virally suppressed by 2020 Why focus on HIV Treatment?
93 countries included in the analysis, based on criteria: More than 1,000 PLHIV in country Eligible for Global Fund funding for HIV in 2014 Countries grouped into the following 6 regions: Africa: West and Central (AWC) - 22 Africa: East and Southern (AES) - 20 Latin America and the Caribbean (LAC) - 14 Middle East and North Africa (MENA) - 9 Eastern Europe and Central Asia (EECA) - 12 Asia and the Pacific (AP) - 16 Country Inclusion Criteria
Projecting Global HIV Treatment Needs
* Depending on current country guidelines as preset in Spectrum. # HIV & TB co-infected with CD4 above 350 (or 500) are a very small proportion; not included in this round of analysis. Used AIM in Spectrum to estimate projected numbers of adult and pediatric patients that are eligible for ART from in each of the 93 countries. Spectrum AIM was used individually for each country Two eligibility scenarios: Current eligibility # : Adult: CD4<350 or 250* and Option B+ (all HIV+ PW) Children: CD4<350 for ages 5-14; CD4<750 for ages mo.; all under 24 mo. (irrespective of CD4) WHO 2013 eligibility # : Adult: CD4<500 and Option B+ (all HIV+ PW) Children: CD4<500 for ages 5-14; all under 5 (irrespective of CD4) a) ART Need: Methods

TUA Progress Report 2013, etc. Coverage: Number on ART on Dec. 31 st / Need for ART, Dec. 31 st Step 1: Established 2013 baseline coverage % for adults and children in each of 93 countries, looking at: Number on ART from 2013 UNGASS country reports; national reports & documents*, or value in Spectrum (in this order) Divided this by current need for ART on Dec. 31 st in the country Step 2: Set possible scale-up paths for countries from this base: 9.17 million on ART in 2012, a 19.8% increase on 2011* Two scale-up scenarios: Slow scale-up: 20% annual increase in coverage % e.g., country’s coverage in 2014: 40%; coverage in 2015: 48% Fast scale-up: 30% annual increase in coverage % b) ART Coverage: Methods

Step 1: Established 2013 split of patients on 1 st vs. 2 nd line ART, adults and children separately (if poss.) By country: UNGASS 2013 country reports, national data, global/regional reports. WHO regional average used for missing Step 2: Define region-specific annual migration rate ranges: % of 1 st line moving to 2 nd line, per year A region has countries classified into “high / med. / low.” This range differs by region. Overall range across regions: 0.5% to 3% p.a. Country designated within region based on resistance*, LTFU, etc. Step 3: Migration scenarios by country over : Base migration: As set above: assumes historical rates continue; increased detection with VL cancelled by lower proximal factors for failure Higher migration: Migration increases from base : Increased patient load stresses systems; higher detection with VL, etc. – greater switching E.g.: Country with low migration moves to medium; medium moves to high c) 1 st & 2 nd line ART: methods * Stanford Drug Resistance Database

Emerging Themes: E 2 in HIV Treatment
Need to increase cost-efficiency: Continue to reduce ARV prices and wider use of low-cost WHO- recommended regimens Example: A 5% reduction in ARV prices could save as much as $1.5 billion from Reduce facility-level costs Example: Reducing proportion of direct costs spent on personnel and overhead by 5% would save as much as $485 million from Reduce lab costs Example: Reducing unit costs of all lab tests to the lowest current price would save as much as $2.5 billion from Need to increase effectiveness: How to increase coverage by 20-30% per year on existing base? Better use of viral load testing to detect and switch on failure Prevent large rise in future 2 nd line treatment need Key Findings
Potential E 2 Gains across ART cascade Interventions that reduce ART costs Interventions that promote sustained viral suppression up to 90% Decentralize, but maintain viable facility- level patient loads Treatment simplification: new methods to deliver ARVs with lower pill burden; long-term dosing Task shifting: reduce per-patient personnel costs Better patient monitoring whether via virological or immunological testing Further expansion of FDC formulations Community-based models of patient monitoring and adherence support Consolidation of lower cost platforms for viral load testing, even at POC; reduction of reagent costs Treat comorbidities, including malnutrition, to keep patient healthy and in care Critical short-term investments (e.g., new VL equipment) may lead to long-term efficiency and effectiveness gains Interventions that help increase coverage up to 90% or more Reduce cross-cutting delivery challenges Eliminate losses across ART cascade (75% lost from test to treat?

HPP Studies on E 2
Lessons Learned from Kenya Efficient interventionsEffective interventions HIV testing; MoH switched testing algorithm to yield highest cost savings while maintaining accuracy Option B+; averts more infant and adult infections than Option B, but at a significant additional cost HCW training; harmonized in-service training curriculum with long-term mentoring is cost- efficient Harm reduction services for key populations; combination package (NSP, MAT, HCT, and ART for PWID) is cost-effective (ICER of $1,600) Screening blood supply for transfusions; cost- benefit ratio of 3 for additional costs to screen all blood vs. averted TTI treatment costs Oral PrEP for sex workers; cost-effectiveness ratio in Kenya is $25 per HIV infection averted; costs could decrease through task shifting New ART guidelines; adopting WHO 2013 guidelines would result in a significant reductions in new HIV infections and premature deaths Workplace interventions; mainstream HIV response, promote prevention programs, fight stigma and discrimination
Lessons Learned from Mozambique Need to increase allocative efficiency: Target geographic regions and population groups contributing the most to HIV incidence Need to scale-up biomedical and behavior change interventions to achieve greatest health impact Revised HIV acceleration plan could avert 113,927 new infections and 145,668 AIDS-related deaths Need both types of interventions to reach goal of halving HIV incidence by 2017
