Ambulatory blood pressure monitoring and the primary care physician.

The primary care physician welcomes technology that will reduce overlabelling and overtreatment of hypertension. Three concerns with respect to ambulatory blood pressure monitoring are: the clear identification of those patients who will benefit from monitoring; the potential for labelling patients prematurely as having technical abnormalities (i.e., 'hypervariability'), which may have little clinical significance; and the inaccessibility of ambulatory monitoring. To determine patient acceptance of ambulatory monitoring, a follow-up survey of 37 patients who used the Spacelab 5200 device was conducted. Twenty-four percent said they would not be agreeable to further monitoring. While newer devices may be less disruptive, the point is made that it is important to include patient assessments in the evaluation of these devices. A comparison is undertaken between ambulatory monitors and the more accessible self-monitoring devices which involve the patient to a greater degree in his/her own care.
