Inclusion criteria

Inclusion criteria: Primary Care Practitioners: 1. Have to provide hypertension care according to a practice protocol based on the guidelines for cardiovascular risk management from the Dutch Association for General Practitioners 2. Should not participate in any similar study to improve cardiovascular risk management Patients: 1. Self-identified as Afro-Surinamese or Ghanaian 2. Aged 20 years and older, either sex 3. Diagnosis of hypertension with International Classification of Diseases, tenth edition (ICD-10) codes I10: Essential (primary) hypertension 4. Uncontrolled blood pressure (BP) (greater than or equal to 140/90 mmHg) at the last office visit. In addition all patients must have an uncontrolled BP at the time of the baseline assessment.

Exclusion criteria

Exclusion criteria: Patients: 1. No diabetes type 1 or type 2 2. No current participation in other cardiovascular disease-related trials 3. The general practitioner who treats the patients judges him/her unfit for participation (e.g., due to co-morbidity) 4. Unable/unwilling to provide informed consent

Design outcomes

Primary

MeasureTime frame
Proportion of patients with a significant reduction in the systolic blood pressure (10 mmHg [standard deviation = 15]), at 8 months after inclusion. We have chosen to use baseline SBP minus SBP after 8 months as the primary outcome measure because SBP is the most important factor in determining a patient's cardiovascular risk profile. In almost all cases the DBP will become lower if the SBP becomes lower.

Secondary

MeasureTime frame
1. The proportion of patients with adequate adherence to prescribed medication at 8 months after inclusion 2. The proportion of patients with adequate adherence to lifestyle recommendations at 8 months after inclusion Data will also be collected with respect to factors that characterise the patient group (baseline demographics, baseline medical chart data) and factors that may influence patients' hypertension management (perceptions of hypertension, perceptions of medications, self efficacy, experienced social support in hypertension management, satisfaction with care).
