17th IAS Conference on HIV Pathogenesis, Treatment and Prevention Kuala Lumpur, 1 July 2013Achieving Universal Access and Moving towards the Elimination of New HIV Infections in CambodiaFirst of all, I would like to express my sincere thanks to the organizer to invite me to speak in this plenary session. It is the great honor for me to share the experience of Cambodia in the last two decades and our perspective for achieving elimination of new HIV infections by 2020.Dr Mean Chhi VunNational Centre for HIV/AIDS, Dermatology and STD (NCHADS) Ministry of Health, Cambodia

3Health Infrastructure 90 Referral Hospitals8 National hospitals24 Provinces77 Operational DistrictsThe health service delivery system consists of two types of facilities – one is the health center providing basic care including ANC, Delivery, TB diagnosis and treatment; the other one is referral hospitals which provide a wider range of clinical care including ART and laboratory services.1,049 Health CentersEach cover 10–20,000 population
4Trends in the HIV Epidemic in Cambodia Cambodia, facing in the mid-1990s one of the fastest growing HIV epidemics in Asia, became within five years one of the few countries to have reversed its trend.We saw a 10 fold reduction in annual new infections in the last 20 years and an 3 fold reduction of annual AIDS related deaths in the last 10 years.The country received a millennium development goal (MDG) award in 2010 from the United Nations as a global recognition of the country’s response to HIV.Source: Conceptual Framework for Elimination of New HIV Infections in Cambodia by 2020 (NCHADS, 2012)4
5Mode of HIV Transmission in Cambodia: 1991 to 2015 Total 1,210Sex work used to be a dominant mode of transmission in 1990’s. The mode has changed over time and the transmissions between spouses and casual partnerships now account for around a half of the total new transmission.5

They include sex workers, brothel owners, local authority, and health workers particularly those involved in STI services.HCSpecial campaigns (Posters, leaflets, bill boards…)
8HIV, behavioral and STI trends among brothel-based sex workers, Phnom Penh We achieved a rapid increase of condom use among sex workers within a few years and we observed reduction of STI and HIV in this population.
9Strategic Expansion of HTC Cambodia 2.0: Rapid ExpansionStrategic Expansion of HTCVCT in all ODs and at ¼ of HCDuring the 2nd phase of the country’s response, we rapidly expanded VCT to cover all operational districts and even health center level.We also introduced PITC in most health centers as well as referral hospitals. In addition, we introduced outreach testing for MARPs recently.PITC for TB and PW in most Health CentersCommunity/Peer Initiated Testing and Counseling for MARPs
10Strategic Expansion of ART Sites For ART, we strategically targeted high burden operational districts for expansion. Out of the total of 77 ODs, ART are available in 55 ODs where 92% of PLHIV in the country were diagnosed.- ART sites in 55/77 ODs covering 92% of PLHIV found- Indicating the need of Satellite ART sites
11Not only expanding services, but systematically linking with the community and creating demand I just would like to highlight that we focused not only service expansion, but systematic linkages with the community and creation of demand among PLHIV.
12Continuum of Care Framework Facilitated Expansion of ART In 2003, we developed this CoC framework together with all the stakeholders including PLHIV network and development partners.This framework facilitated the systematic coordination and service linkages between the community, PLHIV, home-based care NGOs and district health based health services for accelerating access to HTC and maximizing retention in HIV treatment and care.The core of this continuum of care is “MMM” which is indicated in red at the center. What is MMM?(District Level)12
13MMM ActivitiesMMM is a PLHIV friendly mechanism which foster the local partnership among PLHIV, families, NGOs, health workers, religious leaders and local authority.When we were thinking of ART expansion strategy in 2002, we were considering different approaches for service delivery model. Among several options, through extensive consultations, we have concluded the model of partnership between PLHIV network, NGOs and health services should be the way to go.13

In around 2006, we realized that the development of a common “linkage model” would be essential to operationalize both PMTCT and TB/HIV.

18Linkages: Kirivong Operational District 20 HCs have only 2 VCCT sites,1 OI/ART servicesVCCTFor example, we introduced PITC at health center level building upon existing MCH and TB services and established common blood sample referral system linked to referral hospitals.In this district, only 2 sites offered ANC testing – because ANC testing was only offered at those sites co-located with a VCCT site.18
19Linkages: Kirivong Operational District New PMTCT14 HC refer blood samples to 5 sub-satellites &1 satelliteNewNew PMTCTNew VCCTNew PMTCTAfter introducing the ‘linking model’, 4 new VCCT sites were established. Then, health centres were geographically ‘linked’ to their nearest VCCT, allowing for universal ANC testing.New PMTCT19
20Linking Model Demonstration Results (2007-9) Linking Model startedAs a result, a rapid and sustained uptake of HIV testing at ANC was observed. As the green line shows, other MCH services such as syphilis testing can be added on - to achieve rapid ‘universal’ coverage also.* Introduction of syphilis testing in the first quarter of 2009** Percentage of pregnant women tested for HIV/ syphilis at antenatal care out of total expected pregnant women20
21PMTCT CoverageWe used this success in demonstration sites for resource mobilization to rapidly scale-up this approach nation-wide.Together with other elements of linkages, we are improving coverage of PMTCT cascades progressively over the last several years. For example, the coverage of HIV testing and triple ARV prophylaxis or ART in pregnant women doubled from 2009 to 2011.
22TB/HIV CoverageSimilarly, we achieved rapid expansion of TB/HIV collaborative activities. In particular, % of HIV positive TB cases who stated or continued on ART increased by 6 folds within 3 years.
23Moving Towards Integration between HIV-MCH-TBMoving towards integration, we are intensifying the synergies between the three programs. The photo at the top shows “shaking hands” by the dragon, tiger and lion of the three national programs.
24Responding to changing epidemics: Overcoming political, legal and social barriersReaching the most-at-risk populationsLinking them to health servicesLet us now come back to HIV prevention among MARPs. We have tackled multiple challenges, such as (i) Overcoming political, legal and social barriers; (ii) Reaching the most-at-risk populations; (iii) Linking them to health services, in the rapidly changing situation over the last decade.
25Changing conditionsOne big change is the shift from brothel based direct sex work to entertainment establishment based indirect sex work, as well as the increase of sex workers overall.
26Changing conditions (2) 2008 Law on Suppression of Human TraffickingMassive brothel closure, poorly organizedSex workers driven underground increasing vulnerability and riskVirtual collapse of 100% CUP as key partners and structures disappearIncreasing attentions to human rights marginalized populationsAnother change we faced was issuance of a new law of human trafficking. Most brothels were cracked down so that we had to explore new strategies to reach sex workers.

29Key Lessons Learned from Cambodia 2 Key Lessons Learned from Cambodia 2.0: How Cambodia Achieved Universal Access?Know your epidemic and response remains keyStarted with vertical responseCommon service delivery frameworks coordinated by NCHADS involving all stakeholders for strategic expansion“Real” involvement of community (PLHIV and MARPs)Systematic linkages and integration to maximize resourcesI would like to summarize how Cambodia achieved universal access;We invested in strategic information to know our epidemic and chose high impact and low cost interventionsTo control HIV epidemic, focused vertical response was necessary in early phases of the epidemic.I would like to tell you we had NO PILOT PROJECT for HIV in Cambodia because we did not want to see numerous “pilot projects” by different partners, which cannot be expanded. Instead, we WORKED WITH all the partners to develop A SINGLE COMMON service delivery framework for initial learning and then expanded the agreed model to cover the whole country quickly.In Cambodia, we do not have GIPA, but we have RIPA - “Real” involvement of community such as PLHIV and MARPs. They were involved not only service delivery, but also policy formulation, program design and monitoring and evaluation.As the epidemic and the response matured, we shifted from vertical response to linking model and then moving towards integrated approach to maximize resources.

35Current trends in HIV financing With regard to financing of the national HIV program;Given Cambodia’s Low-Income-Country status, our response is 90% dependent on international funding – mainly the Global Fund and PEPFAR.Since the external funding started to decline, it is urgent for our country to increase domestic contribution to achieve our elimination goal and sustain it.Source: NASA IV Report, 201335
