Adherence to treatment — a pivotal issue in long-term treatment of patients with cardiovascular diseases. An expert standpoint

Abstract

The adherence to treatment is defined as the extent to which a person’s behaviour, including taking medication, following a diet, and/or executing lifestyle changes, corresponds with agreed recommendations from a health-care provider. Non-adherence to medication may lead to increased morbidity, mortality, and costs to the healthcare system. Therefore, it is pivotal to know the patient’s true adherence to medication, understand the causes of low adherence, and take actions to improve adherence. The authors assumed that individual, complex health education started during hospitalisation and continued after discharge, explaining the pathophysiology and symptoms of the disease, elucidating goals and potential benefits of treatment, and highlighting the risk of premature termination of therapy, with use of additional methods helping patients to remember treatment schedule will enhance adherence to treatment. There is an urgent need to develop and test a dedicated procedure covering all these activities. Introduction. A substantial proportion of patients with cardiovascular diseases do not respond to the treatment sufficiently [1–3]. Several factors of poor response to medication should be taken into ac-count, including inadequate drug intake [4–6]. To systematise the phenomenon of following medical recommendations, the term “adherence” was proposed. The World Health Organisation (WHO) defines “adherence” as “the extent to which a person’s behaviour, including taking medication, following a diet, and/or executing lifestyle changes, corresponds with agreed recommendations from a healthcare pro-vider” [7]. Adherence has been also defined as the “active, voluntary, and collaborative involvement of the patient in a mutually acceptable course of behaviour to produce a therapeutic result” [8]. Previously the term ‘compliance’ was widely used, particularly in negative concord as ‘non-compliance’. Nowadays ‘compliance’ is associated with a more pejorative connotation than ‘adherence’ because ‘non-compliance issues’ are mostly patient-oriented without a deeper view into the different set of factors, e.g. obstacles identified in the healthcare system. Thus, currently in scientific deliberations we usually prefer usage of the term ‘adherence’ [9].
