"Drugs Don't Work in Patients Who Don't Take Them"

The more recent term "adherence" is now taking the place of the earlier notion of "compliance," as it emphasizes the physician-patient partnership. To date, however, it has not been clearly defined. There are many limitations to measuring adherence, and presently no standard methods have been established. Even in clinical trials throughout medicine, the reported rates for adherence range only between 43 % and 78 %. Particularly medication adherence is highly relevant to the treatment of mentally ill adolescents, as they make up a population especially vulnerable to nonadherence - and high rates thereof have been reported. Factors influencing adherence are poorly understood and researched, especially in adolescents with mental illness. Physicians can currently rely only on concepts from other populations and expert recommendations. Concepts for children or adults should not directly be transferred to adolescent patients. Results from the current "SEMA" study should contribute to guiding future research in the development of interventions to improve medication adherence, in particular for this juvenile population.
