RESUMO
BACKGROUND: Factors contributing to non-adherence have become a priority for clinicians, healthcare policy makers, and healthcare payers alike. Patients who are non-adherent to their medication regimen appear to have poor health outcomes, with evidence of both high mortality rates and high morbidity in the form of more frequent emergency room admissions, recurrent exacerbations of disease, and poor overall well-being. The primary objective of this study was to identify and describe patient-identified factors associated with non-adherence in patients maintained on chronic hemodialysis. METHODS: A 23-item questionnaire was developed and validated for use in the hemodialysis population. This questionnaire was administered to patients undergoing chronic hemodialysis in a single center during the period of October to December 2013. RESULTS: A total of 156/183 eligible patients consented. Of these 156 patients, 36 (23%) patients reported being non-adherent. The most common non-adherent behaviors were changing the frequency of taking medications and skipping doses. Patients identified information gaps around medication interactions, the flexibility around drug timings, and how best to manage medications that needed to be taken apart from, with, or without food. CONCLUSIONS: Our study shows that, despite an intensive drug education program, almost one quarter of patients continue to have problems with taking medication and that traditional education around medications is insufficient. We propose that clinicians customize education to the patient-driven gaps in knowledge, in particular focusing on the education needed to empower patients to recognize which aspects of their care they can and should modify and which aspects require further clinician input.
