Identifying strategies to inform interventions for the secondary prevention of stroke in UK primary care
Stroke is a significant contributor to the global burden of disease in adults. With the risk of recurrent stroke high, preventative medicines aimed at risk factor reduction are the method of choice for addressing the challenge of increased morbidity and mortality and improving patient outcomes. Research in stroke has shown that adherence to medication is problematic and survivors face considerable practical and physical barriers to taking prescribed medicines. Understanding these challenges can inform the development of strategies to improve medication taking behaviour through delivery of interventions in the primary care setting. This thesis aims to identify potential strategies to inform interventions to improve medication taking in stroke. The research: identified key barriers and facilitators of medication adherence for the secondary prevention of stroke – firstly from within the primary care setting and then from the perspective of an online stroke forum; explored the appropriateness of the online forum as a method of data collection for conducting qualitative research compared with a traditional qualitative interview approach; investigated medication taking among community stroke survivors to characterise patients who receive help with medicines and estimate the proportion who have unmet needs and miss medicines; and examined attitudes from across the stroke spectrum towards a novel approach to medication taking for secondary prevention (i.e. fixed-dose combination polypill). Findings showed that survivors face considerable barriers to medicine taking, but that facilitators, particularly the caregiver role, can encourage good medication taking practice. The online forum has potential as a source of data to understand stroke survivors’ behaviour, and a novel strategy to taking stroke medicines has promise. These findings enhance current thinking around medicine taking behaviour in stroke and can inform the development of effective interventions to improve medication taking practices and address nonadherence among stroke survivors. Implications for clinical practice are discussed, and recommendations are provided for future research.
