Adherence and concordance
Patients make important contributions to rational prescribing decisions. Their beliefs and expectations affect the goals of therapy and help in judging the acceptable benefit/harm balance when selecting treatments. They will often play a key role in monitoring treatment, not least by providing early warning of adverse events. Patients who have been involved in clear communication with prescribers concerning reasons for drug selection, goals, duration of treatment, and potential adverse effects have improved adherence to treatments, more confidence in prescribers, and greater satisfaction with health-care services. Thus, patients should, whenever possible, be fully informed about their medicines.
