Abstract
Adherence determines the effectiveness of a treatment or medication plan aimed at providing individuals with optimal health. In contrast, nonadherence occurs when a patient fails to follow the treatment plan by either intentional or unintentional nonadherence. Nonadherence rates vary across diseases, but, on average, 50% of patients are nonadherent. Nonadherence can have physical, emotional, and financial consequences for patients. There are numerous predictors of adherence that are sometimes grouped as patient-related factors, regimen-related factors, provider–patient interaction level factors, and healthcare system-related factors. No one intervention approach has proven to improve adherence in all cases; multifaceted interventions tend to be most effective.
