Treatment of Hypertension: an Interventional Approach to Improve Blood Pressure Control (DRIVE)

August 27, 2019 updated by: Ulla Hjørnholm, Oslo University Hospital
The purpose of the study is to access the change in mean daytime systolic blood pressure in participants with essential hypertension not adequately controlled (defined as mean systolic daytime ambulatory blood pressure ≥ 135 mmHg) and randomly assigned to either an intervention group with one-time only Direct Observed Therapy (DOT) immediately followed by ABPM or a control group with standard ABPM.

Detailed Description

More than 1 billion people world wide suffer from hypertension (HT), leaving it the world´s top rank risk factor and contributor to global disease burden. Cardiac disease, stroke, kidney disease and dementia are diseases related to HT with high economic burden on societies and each year 9.4 million people die as a direct consequence of HT.

Estimated < 50 % of hypertensive patients adhere to preventive hypertensive medication after 1 year of treatment.

Poor adherence to antihypertensive treatment have by many been explained partly by the silent nature of hypertension, the risk of side effects from antihypertensive medication, treatment expenditures and the patient health perspectives.

In a randomized controlled trial design we plan to enrol 20 subjects, the limited number explained by the study being part of the initial planning of a larger scale trial organized by the research group, to invistigate the change in ambulatory bloodpressure with or with out Direct Observed Theraphy prior to meassurement, as a one-time-only medication adherence check.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control
Standard care
Experimental: Direct Observed Therapy
Direct Observed Therapy immediately followed by mounting of ambulatory blood pressure device and measurement of ambulatory blood pressure according to ESH 2013 guidelines.
Other: Direct Observed Therapy
Patients allocated to the intervention group take their medication (from original blister packaged) in front of the invistigator who observe the patient swallowing the medication. To secure the principals of Direct Observed Therapy, the patient do not leave the clinic for two hours.
Other Names:
  • DOT
