Study Overview
Brief Summary
Hypertension is the leading modifiable risk factor for cardiovascular disease and is implicated in half of all strokes and myocardial infarctions. One-third of adults in Scotland have hypertension yet only one-quarter of these have their blood pressure (BP) controlled to target (<140/90 mmHg). Reasons for the low rate of control are varied but include individuals lack of confidence, knowledge and understanding of the condition and treatment strategy, non-adherence to medication and infrequent BP monitoring. These issues have been compounded by the ongoing COVID-19 pandemic which has brought changes in routine BP screening, access to medical care and chronic disease management in primary and secondary care, shielding of the highest risk groups and a change in health and research focus. Shared decision making and issues around health literacy were highlighted by the Scottish Government Cross Party Group on Heart Disease and Stroke: High Blood Pressure Task Force in 2019. Empowering patients to have a better understanding of their condition and becoming actively involved in the monitoring and management of hypertension may lead to improved patient satisfaction, improved BP control and health outcomes and reduction in the use of primary/secondary care hypertension clinics.
