Plain English Summary
Background and study aims
Hypertension (high blood pressure) is a long term medical condition in which the pressure in the arteries is higher than it should be. It is major risk factor for cardiovascular disease (disease of the heart and blood vessels), which can lead to heart attack and stroke. Although there is a wide range of medications available that help lower blood pressure, many patient's still have poorly controlled blood pressure. In addition, for effective blood pressure control, many patients need to take more than one blood pressure medication. Having to take a lot of pills increases the risk that patients may not stick to their treatment program, leading to poor blood pressure control. The aim of this study is to complete a large-scale survey to investigate the motivation and key drivers in the therapeutic decision making process to improve (simplify or intensify) blood pressure medication treatment in patients with poorly controlled high blood pressure at general practitioners in Belgium and Luxembourg.
Who can participate?
Adults with high vlood pressure who are taking at least one blood pressure medication, are seen by a general practitioner in Belgium or Luxembourg.
What does the study involve?
Participants attend an appointment with their GP, who records information about their background, current medical treatment, and blood pressure. Based on this information the GP decides whether any changes are needed in the current medical treatment. The information is then collated in order to find out whether there are any patterns in a GPs decision to simplify or intensify blood pressure medication treatment.
What are the possible benefits and risks of participating?
There are no direct benefits or risks involved to those taking part in the study.
Where is the study run from?

When is the study starting and how long is it expected to run for?
January 2017 to September 2017

Cross-sectional survey evaluating the motivation and key drivers of general practitioners to SIMPLIFY or intensify antihypertensive treatment in the general uncontrolled hypertensive population treated with at least one antihypertensive agent in Belgium and Luxembourg
The aim of this study is to evaluate the motivation and key drivers of general practitioners to simplify or intensify antihypertensive treatment in uncontrolled hypertensive patients already treated with at least one antihypertensive drug.
Due to the observational nature of this study, it does not require ethics approval according to the European directive and Belgian law. Nonetheless, the study has been approved by pharma.be (Bureau Des Visas Études Scientifiques Décision, 31/01/2017, ref: 17/01/20/01)

Patient information sheet
Not available in web format, please use the contact details below to request a patient information sheet
All participants attend an appointment to see their general practitioner, who is asked to record the following information:
1. Age, sex, weight and height of the patient
2. number of years previously being treated with antihypertensive drug(s)
3. Presence of comorbidities (specify: diabetes, renal insuffisciency, prior CV complications, heart failure, arritmia, renal insufficiency, dyslipidemia or other)
4. Systolic and diastolic blood pressure
5. compliance to antihypertensive treatment
6. Medical treatment before consultation /
6.1 need to change current medical treatment? (yes/no)
6.2 if 6.1 yes: Medical treatment after consultation
6. If the patient has been prescribed a single pill combination, for which reason? (better compliance, better prognosis, cheaper, better control of blood pressure, simpler for the patient?)
The information collected by the GP is data collected routinely by the GP during a standard consultation for hypertension. No other data than data needed for the patient file is collected. Based on the collected patient information and the performed medical decision making, it will be calculated which variables are the main drivers for simplification or intensification of the antihypertensive treatment.
Primary outcome measure
Change in antihypertensive treatment (yes or no) in relation to blood pressure values (controlled or uncontrolled blood pressure) is assessed using information collected at the GP appointment.
Secondary outcome measures
1. Change in antihypertensive treatment (yes or no) in relation to therapeutic compliance is assessed using information collected at the GP appointment
2. Change in antihypertensive treatment (yes or no) in relation to total pill burden is assessed using information collected at the GP appointment
3. Change in antihypertensive treatment (yes or no) in relation to antihypertensive pill burden is assessed using information collected at the GP appointment
4. Change in antihypertensive treatment (yes or no) in relation to type of antihypertensive treatment is assessed using information collected at the GP appointment
5. Change in antihypertensive treatment (yes or no) in relation to comorbidities/CV risk is assessed using information collected at the GP appointment
6. Change in antihypertensive treatment (yes or no) in relation to patient demographics is assessed using information collected at the GP appointment
