Abstract

Medication nonadherence is common and results in avoidable morbidity, mortality, and burdens on healthcare systems. This paper proposes a preventative approach to medication nonadherence. We consider existing evidence on the prevalence and determinants of nonadherence early in a patient’s medication-taking journey, and map these to potential opportunities for intervention. Many patients stop taking a new medication soon after they are prescribed it, often not collecting the medication. Early patterns of nonadherence are linked to later nonadherence via processes such as habit formation and symptom experiences. Known predictors of nonadherence may be present before someone starts a new treatment, when patients experience disruption to their lives and identity due to illness. Healthcare professionals typically have contact with patients around this time. We argue that it may be possible to prevent medication nonadherence: at the population level; by optimising the prescription process; and through low- and high-intensity interventions for patients with identified early barriers. We give examples of specific interventions and tools that might be needed to operationalise this approach in practice and propose new directions for research to promote early engagement with medication to prevent nonadherence.
