Is Ending AIDS in Thailand feasible and implementable ? Yes, But……….
5
Several Factors Support “Yes” 1.The national AIDS committee has approved this policy together with a significant supported budget 2.HIV treatment and care system have been well established and continuingly improved in Thailand 3.Thailand does have a very powerful e-registry database “National AIDS Program plus pr NAP+” and it has been used to monitor and improve the quality of care 4.Key relevant information are available: HIV care cascade, key-affected populations, key geographical targets 5.A large implementing research on test &treat in MSM among 8 provinces have been started. This will help to guide the other 27major effected provinces to implement their Test&Treat policy 1.The national AIDS committee has approved this policy together with a significant supported budget 2.HIV treatment and care system have been well established and continuingly improved in Thailand 3.Thailand does have a very powerful e-registry database “National AIDS Program plus pr NAP+” and it has been used to monitor and improve the quality of care 4.Key relevant information are available: HIV care cascade, key-affected populations, key geographical targets 5.A large implementing research on test &treat in MSM among 8 provinces have been started.

How to detect failure and DR? Time-course of HAART Failure Clinical Started HAART 1 234 5 Non- Adherence Non- Adherence Viral load Resistance CD4 drop Time (months –years) Thai NHSO guidelines: VL q 6 mo, until VL<50, then q 1 yr CD4: q 6 mo, until CD4 >350, q 1 yr Thai NHSO guidelines: VL q 6 mo, until VL<50, then q 1 yr CD4: q 6 mo, until CD4 >350, q 1 yr

Current Thailand NAP policy for free CD4 and VL monitoring support Lab testNumber of free tests per year Viral load2 /yr until undetectable then 1 yearly CD42 /yr until CD4 ≥350, then 1 /yr (Remark: in practice if CD4>500, we may not need to FU CD4, as long as the VL is <50 c/ml) HIV Resistant test When VL>1000 c/ml

Key steps to Test and Treat Effective MSM CSWs+ Clients CSWs+ Clients PWIDs Spousal Tm New Diagnosed Cases With high CD4 count Media Reach Out Routine Testing Annual Check up How to significantly increase testing uptake? In at least 25 of 76 provinces (contributing to 2/3 of total new infection) Getting ART Indicators No. of case BL CD4 increased Retained on ART with good VC New infection rate monitoring Time to Dx to ART % on ART % Drop out % VL tested % VL<50 % VF with 2 nd Line New infection <1000/y Normalize HIV
13
How academia can contribute in the National Ending AIDS Policy? 1.Implementation research : to identify proper and effective ways to improve the current HIV care cascade 1.Reach out approaches : applicability of different settings 2.Which POC test (CD4, VL) should be used in different settings 3.Researches to optimize ARV doses or regimens that will further improve treatment adherence 2.National HIV treatment guidelines 2014 3.AIDS expert committee to work with regional/ provincial M&E committee to support improving quality of the TnT services by the use of data generated from the NAP+ db 4.The Thai AIDS Society (TAS) together with the NAP to support a friendly online consultation system for doctors and nurses from less experienced clinic and comminity-services 1.Implementation research : to identify proper and effective ways to improve the current HIV care cascade 1.Reach out approaches : applicability of different settings 2.Which POC test (CD4, VL) should be used in different settings 3.Researches to optimize ARV doses or regimens that will further improve treatment adherence 2.National HIV treatment guidelines 2014 3.AIDS expert committee to work with regional/ provincial M&E committee to support improving quality of the TnT services by the use of data generated from the NAP+ db 4.The Thai AIDS Society (TAS) together with the NAP to support a friendly online consultation system for doctors and nurses from less experienced clinic and comminity-services

How a Country-program Manager Should Design their Proper ART Lab Monitoring Services ? Central Laboratory Clinical settings Community- based settings Conventional flow cytometry-based CD4 count Conventional VL testing HIV drug resistance testing Safety lab profiles POC diagnostic test POC CD4 test POC VL test (+/-) Simple safety lab tests?

19
Lessen Learnt from Bangkok AIDS Committee (BAC) How NAP data-Driven Model can help to Improve HIV Care Quality?
20
BAC Strategies to Improve the hospital Performances on HIV Care in Bangkok BAC has meeting q 3-4 months to review and monitor the key indicators of each hospital Any hospitals with a defined “red alert” indicator especially on low % VL control will be arrange for a supervision visit Each year, the best performed hospitals by “the targeted criteria : >75% of patients had VL tested and with >75% have VL <50 c/ml” will be awarded during the annual meeting BAC has meeting q 3-4 months to review and monitor the key indicators of each hospital Any hospitals with a defined “red alert” indicator especially on low % VL control will be arrange for a supervision visit Each year, the best performed hospitals by “the targeted criteria : >75% of patients had VL tested and with >75% have VL <50 c/ml” will be awarded during the annual meeting

Proportion Patients with VL 100 patients) Overall VL<50 = 71% National AIDS Program (NAP), Thailand. As of October 9, 2008 N= 124 N= 182 376
22
Reality: Not All Services are Performing Well Thailand NAP, Bangkok Region -Achievements Bangkok AIDS Program Treatment targets 1.≥75% of patients are tested for VL once a year, plus 2.≥ 75% of patients tested have VL<50 c/ml 18% (11/59) achieved this ≥75% target Only 5% of hospitals achieved ≥ 85% of VL<50% 18% (11/59) achieved this ≥75% target Only 5% of hospitals achieved ≥ 85% of VL<50% Bangkok NHSO, March 2012 N=13,280 in 59 hospitals
23
Latest performance of hospitals in Bangkok Overall % patients with VL tested was >75% And the latest overall % with undetectable VL was >80% There were however a few hospitals that still require site visit and further support Overall % patients with VL tested was >75% And the latest overall % with undetectable VL was >80% There were however a few hospitals that still require site visit and further support

Options after First-line Failure NRTI in the failing regimen NRTI optionThird ARV option TDF failure Guided by resistance test results, or Consider : AZT/3TC Preferred : Lopinavir/ritonavir (LPV/r)* Alternative: Atazanavir/ritonavir (ATV/r), darunavir/ritonavir (DRV/r) AZT or ABC failure Guided by resistance test results, or Consider :TDF/FTC or TDF/3TC
