Abstract

Background

A significant proportion of the atrial fibrillation (AF) population attending Australian primary care is not receiving guideline-adherent oral anticoagulant (OAC) treatment. This study aimed to explore reasons for non-adherence to thromboprophylaxis guidelines in AF from the perspectives of general practitioners (GPs) and to map these reasons to the Capability, Opportunity, Motivation-Behaviour (COM-B) model to identify potential opportunities to support practice change.
Methods

An exploratory qualitative descriptive study among GPs practising in Western Australia was conducted using semi-structured interviews, from November 2020 to February 2021. The Framework Method was employed to facilitate thematic analysis, using NVivo software. Interview responses were also mapped to the COM-B model.
Results

Nine of the 10 GPs initially consented participated in the semi-structured interview (Male = 56%, median age = 52 years, data saturation reached with 6 participants). Two themes emerged from analysis of the interview transcripts: (1) GPs' decision-making process and (2) Patient refusal to take OACs. The COM-B model mapping identified behavioural factors that could impact adherence: capability (GPs' knowledge and understanding of AF guideline recommendations), opportunity (access to a cardiologist, and patients' refusal to take OACs), and motivation (using formal bleeding risk assessment tools).
Conclusion

GPs identified various reasons contributing to non-adherence to thromboprophylaxis guidelines in patients with AF. Multifaceted interventions should consider behavioural opportunities to improve adherence, including education and training, electronic decision support, clinical audits by allied health professionals, partnership between general practices and local hospitals, and cardiologist-led interventions to support GPs. Further studies are needed to capture patients' reasons for refusing OACs.
