Éxito TAR adherencia

• La adherencia es un factor predictor de:

– Supresión viral mantenida

– Reducción riesgo de desarrollar resistencias

– Menor progresión de infección

– Menor tasa de hospitalización

– Mayor supervivencia

Factores relacionados con la adherencia

complejidad, efectos adversos e interacciones

mala relación médico‐paciente

toxicomanías

enfermedad mental, deterioro neurocognitivo

bajo nivel educativo

barrera idiomática,

falta de apoyo social

Choosing a Single-Tablet Regimen for HIV Therapy

Summary: Observational Studies of STRs vs Multicomponent RegimensStudy Main Finding

LifeLink Database[1]

(N = 7073)STRs associated with higher rate of adherence and lower risk of hospitalization

Commercially insured US HIV pts[2]

(N = 6938)

Non STRs associated with 1.5 x risk of incomplete dosing; partial adherence associated with increased rate of hospitalization

Quebec Cohort[3]

(N = 4996)Higher proportion of STR pts adherent to therapy; STRs also associated with lower rate of hospitalization and healthcare utilization

VA Cohort[4]

(n = 15,602)STRs associated with significantly better adherence, lower hospitalization rate

CANOC Cohort[5]

(N = 2965)RAL + 2 NRTIs had lower risk of discontinuation vs EFV/TDF/FTC

� Limitation: cannot control for all factors leading to selection of STRs that may also be associated with good outcomes (first-line regimens, lack of psychiatric disease/substance abuse, provider-perceived good adherence, low risk of resistance)
