Substantial attrition between testing and ART initiation 15-30% lost at each step Mugglinet al, Trop Med Int Health 2012
Still too many people start ART late 1 in 4 start ART at CD4<100 The IeDEA and ART cohort collaborations

Improving testing and linkage • Partner and couples testing • Community testing • Self-testing • Combination testing • DBS for early infant diagnosis Suthar et al, Plos Med 2013 [Accepted] Global Update on HIV treatment, WHO, 2013
Enrollment in pre-ART care Enrollment in pre-ART care Adherence clubs • Earlier initiation • PoC CD4 • CTX • Adherence clubs CTX prophylaxis PoC CD4 Wynberg et al, 2013 (submitted) Kohler et al, AIDS 2011 Wynberg et al, 2013 (submitted) Kohler et al, AIDS 2011
ART initiation Paediatric decentralization in Thailand • Task shifting • Decentralization • Service integration TB/HIV integration India Global Update on HIV treatment, WHO, 2013 Kredo et al, Cochrane Database of systematic reviews, 2013. PMTCT B+ in Malawi
Adherence support Fixed-dose combinations • FDCs • Optimized regimens • Viral load • Adherence support (sms, clubs…) Wilkinson, SAJHIV Med 2013; Ford et al, 2013 (submitted); Butler et al, IAS 2013
Summary • Successful scale up of ART poses continued challenges to current models of care • Evidence from research and programmes indicate ways to improve patient care at each step of the cascade • Future research is needed to identify approaches to enroll people earlier onto ART and support long-term retention in care
WHO’s ongoing workto support ART delivery • Support to regions for guideline rollout • Future of ART monitoring • Phasing out (d4T) and phasing in (viral load) • Early Infant Diagnosis • Paediatric treatment optimization • Cotrimoxazole prophylaxis • Implementation Science summit
