  1. IMPLEMENTING CLINICAL RECOMMENDATIONS: ART STRATEGIES, TOOLS, AND HEALTHY SYSTEMS/SERVICE DELIVERYRECOMMENDATIONS 11-14: ADHERENCEJohn G. BartlettJohns Hopkins UniversitySchool of Medicine 

  2. The Continuum of HIV Care -- US 80% 77% 66% 89% 77% Of all with HIV infection, 850,000 individuals do not have suppressed HIV RNA (72%) MMWR (60), 2011

  3. ART Strategies • Among regimens of similar efficacy and tolerability, once-daily regimens are recommended for treatment-naivepatients beginning ART (II B). • Switching treatment-experienced patients receiving complex or poorly tolerated regimens to once-daily regimens is recommended, given regimens with equivalent efficacy (III B). • Among regimens of equal efficacy and safety, fixed-dose combinations are recommended to decrease pill burden (III B).

  4. Adherence Tools for Patients • Reminder devices and use of communication technologies with an interactive component are recommended (I B). • Education and counseling using specific adherence-related tools is recommended (I A).

  5. Education and Counseling Interventions • Individual one-on-one ART education is recommended (II A). • Providing one-on-one adherence support to patients through 1 or more adherence counseling approaches is recommended (II A). • Group education and group counselingare recommended; however, the type of group format, content, and implementation cannot be specified on the basis of the currently available evidence (II C). • Multidisciplinary education and counselingintervention approaches are recommended (III B). • Offering peer support may be considered (III C).

  6. THE NON-VALUE OF PILL COUNTS: FEM-PrEP (Van Damme. NEJM 2012) Trial: Randomized, double-blind placebo-controlled trial in 2,120 HIV negative women in South Africa. Results Placebo TDF/FTC n=1,058 n=1,062 Adherence report 95% 95% Pill counts 88% 88% TDF levels >10 ng/mL Failure ----- 15% No failure ----- 24%

  7. WHAT TO START Guideline Backbone 3rd Drug DHHS, IAS-USA TDF/FTC EFV, RAL, British ATV/r, DRV/r European TDF/FTC EFV, NVP ABC/3TC ATF/r DRV/r LPV/r, RAL WHO TDF/3TC EFV, NVP AZT/3TC

  8. ART REGIMEN: REGIMEN SELECTION Goal: NDV, avoid resistance, ADR Factors in the decision: • Baseline resistance test • Co-morbidities: Core, Renal, HBC, Pregnancy, Psychological issues • Potency: Undefeated regimens • Urgency: Pregnancy, HIVAN, AIDS, Primary HIV • Resistance to resistance: FOTO (EFV) and PI/r • Cost and coverage

  11. COST OF CARE Contemporary costs/yr. (AIDS 2010;24:2705) • HAART $12,000 (72%) • Meds (other) $ 2,100 • In-patient $ 600 • Out-patient $ 400 Total (Meds) $ 16,600 Growth: 40,000/yr survival + T&T all: $800 million

  15. P4P4P: THE STATUS OF PAYING PATIENTS FOR SELF CARE Practice: Widespread and international Incentives: Cash, groceries, lottery tickets, meal tickets. Conditions: Chronic – smoking, obesity , BP control, diabetes, HIV HIV trial: HPTN 65 – Controlled trial, (unblinded) HIV test – $25, Enroll in care – $70, NDV – $280/yr (1.7% of HIV care cost) Status: Widely practiced, no one wants to talk about it.

  16. A TEST OF FINANCIAL INCENTIVES TO IMPROVE WARFARIN ADHERENCE(Volpp KG. BMC Health Sys Res 2008;8:272)

  17. THE POWER OF HOPE (Harris J, De Angelis. JAMA 2012;300:2912) “With a deeper understanding of the science of care, physicians will increasingly realize that a meaningful patient-physician relationship leaves each patient better able to adhere to the treatment plan.”

  18. HEALTHCARE OUTCOMES IN HIV:REDUCING DISPARITIES (Moore R. CID; in press) Issue: Major issue in HIV care is retention in care and adherence Method: Moore Clinic data 1995-2010 N=6,366 Pt/yrs 27,941 Demographics: B – 77%, F – 34% Risk: IDU-45%; MSM – 30% Insurance: Private – 15% Results: Calculated life expectancy at age 28 yrs = 73.4 yrs for all groups – race, gender and risk

  21. ART ADHERENCE IAPAC GUIDANCE: Scientifically validated systematic approaches Regimen selection: • Drugs that will work (science) • Drugs patients will take (art) Factors to consider: • Documentation metric: VL • Impact of patent expiration • Cost-support services • P4P4P • Clinic viral load
