IMPLEMENTING CLINICAL RECOMMENDATIONS: ART STRATEGIES, TOOLS, AND HEALTHY SYSTEMS/SERVICE DELIVERY RECOMMENDATIONS 11-14: ADHERENCE John G. Bartlett Johns Hopkins University School of Medicine May 2012www.iapac.org

THE CONTINUUM OF HIV CARE -- US MMWR (60), 2011 Of all with HIV infection, 850,000 individuals do not have suppressed HIV RNA (72%) 100% 75% 50% 25% 80% 77% 66% 89% 77%

Among regimens of similar efficacy and tolerability, once-daily regimens are recommended for treatment-naive patients 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). ART STRATEGIES

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). ADHERENCE TOOLS FOR PATIENTS

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 counseling are 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 counseling intervention approaches are recommended (III B). Offering peer support may be considered (III C).

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.

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.”
