Introduction: Due to various influences such as white-coat hypertension, white-coat normotension, or fluctuating compliance between visits to the office ("treatment holidays"), it has been suspected that office bp measurements do not accurately represent the course of a patients (pts) bp curve. A better view may be obtained from the pts self-measurements, provided these are recorded correctly.

To ensure the desired correct documentation and also to enable doctors to do frequent checks of the course of the pts bp, an uncomplicated telemonitoring method would be most useful. A pilot study was undertaken to determine the feasibility of bp telemonitoring.

Methods: Every patient was given a bp measuring device fitted with an upper arm cuff and a built-in modem. Pts were asked to measure their bp twice daily. Obliterating the need for the pts intervention, the data were regularly transmitted to a competence centre where the bp values were interpreted and graphically depicted. The processed data were then retransmitted to doctors. In an additional survey, doctors were asked for their assessment of the procedure.

Results and conclusion: 74 patients (male 43, mean age 61 ys; female 31, mean age 54 ys) and 22 doctors (GP or cardiologists) participated for 4 weeks in this pilot-project. The compliance concerning daily blood pressure measurements of nearly all patients was about 90%. About 80% answered an evaluation questionnaire at the end showing that 89% considered handling of bp-monitor devices as good or very good. The new technology was very well accepted by patients and participating doctors. Detailed analysis will be presented. In future it has to be proven if consequent use of telemonitoring device will improve long-term blood pressure control.
