Clinical pharmacists' perspective of medication adherence support in Ethiopian hospital settings: a qualitative study

Abstract

Background: Hospital pharmacists can assist patients with medication adherence in a hospital setting. No studies have explored the views of hospital pharmacists on medication adherence. Objectives: The study aimed to explore Ethiopian clinical pharmacists' understanding of and experience with medication adherence, and identify strategies for medication adherence support. Methods: Semi-structured interviews were conducted via ZOOM/Skype. Hospital pharmacists were recruited through a professional network and snowball sampling. All interviews were audio recorded, transcribed verbatim, translated into English and analysed using thematic analysis techniques. The data coding followed a hybrid deductive and inductive approach. Key findings: Fourteen Ethiopian clinical pharmacists participated in the study. Analysis yielded five main themes including: medication adherence definition and measurement; pharmacists' perceived roles; enablers of medication adherence; barriers to medication adherence; and ways forward. Participants indicated that accurately assessing medication adherence was complicated because of an absence of cost-effective and validated tools. Pharmacist education, clinical pharmacy services, physical structure, sources of medication information, and government initiatives to reduce financial burdens were the facilitators identified. Eight barriers were identified, and these were broadly classified as factors intrinsic or extrinsic to the patient. Conclusions: Medication adherence support could face barriers intrinsic or extrinsic to patients. Strategies were proposed to overcome the identified barriers and to harness existing facilitators. These strategies included the need for validated local language medication adherence tools, instituting regular adherence measurement and prioritizing patients for available interventions. Patient's preferred dosage form should be considered along with medication complexity and medication knowledge when supporting medication adherence.
