Comparison of Blood Pressure Measurement With an Omron HEM-907 Device in a Clinical Setting and a Research Setting (OMRONHEM-907)

April 10, 2018 updated by: Maxime Lamarre-Cliche, Institut de Recherches Cliniques de Montreal
Automated office blood pressure (AOBP) devices are recommended for high blood pressure diagnosis. One of those devices is the Omron HEM-907 (Omron Healthcare). It is currently not known if blood pressure measurements performed with this device in a clinical setting are equivalent to those made in a research setting. Therefore, this randomized-controlled trial was designed. It aims to compare the blood pressure measurements performed in a clinical and a research setting. Seventy patients will be included and randomized to a clinical/research or research/clinical sequence.

Detailed Description

Hypertension is a common condition, with an estimated prevalence around 20 percent in Canada. It is a major risk factor for cardiovascular disease. Recently, Hypertension Canada has updated its guidelines and recommend we should consider a 120 mm Hg systolic blood pressure target in high-risk patients aged 50 years or older. This recommendation derives mainly from the SPRINT trial. In this trial, blood pressure was measured with an automated oscillometric blood pressure (AOBP) device, the Omron HEM-907 (Omron Healthcare). However, it is not known if measurements performed with this device in a clinical setting are equivalent to those made in a research setting. Therefore, this randomized-controlled trial was designed. It aims to compare the blood pressure measurements of 70 patients in a clinical and a research setting. Patients will be randomized to a clinical/research or a research/clinical sequence.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Sequence: Clinical/Research
Participants assigned to this arm will have their blood pressure measured in a clinical setting first, and in a research setting second. The sequence randomization corresponds to the intervention. Visits will be at least a day apart but within a two-week period. During the clinical visit, they will have their blood pressure measured with the Omron HEM-907, an automated office blood pressure (AOBP) device. During the research setting, participants will be guided through a series of research-driven steps such as study questionnaires and completion of consent forms. They will have their blood pressure measured in both arms with a mercury sphygmomanometer, and then 3 measurements with a mercury sphygmomanometer. AOBP measurements (Omron HEM-907) will be performed at the end of the visit.
Other: Sequence: Clinical/Research
Participants will be assigned to a sequence of: research visit first/clinical visit second.
Active Comparator: Sequence: Research/Clinical
Participants assigned to this arm will go through the same measurements and procedures exception made of the research-first and clinical-second sequence. The intervention to which they are randomized corresponds to the sequence of the visits.
Other: Sequence: Research/Clinical
Participants will be assigned to a sequence of: clinical visit first/research visit second.
