Objective Current guidelines recommend that self monitoring of blood
pressure at home should only be performed using validated devices. This
study assessed the accuracy of the Microlife WatchBP Home device for
self home blood pressure measurement according to the European Society
of Hypertension International Protocol.
Methods Thirty-three participants were included (15 in phase 1 and an
additional 18 in phase 2). Simultaneous blood pressure measurements were
taken by two observers (Y-tube-connected mercury sphygmomanometers) four
times sequentially, with three measurements taken using the tested
device. Absolute differences between observer and device measurements
were classified into three zones (within 5, 10 and 15 mmHg). The number
of measurements with a difference within 5 mmHg was calculated for each
individual.
Results In phase 1, the device produced 38, 43 and 43 measurements
within 5, 10 and 15 mmHg, respectively, for systolic blood pressure and
35, 45 and 45 for diastolic blood pressure. In phase 2.1, the device
produced 75, 91 and 97 measurements within 5, 10 and 15 mmHg for
systolic, and 74, 93 and 99 for diastolic blood pressure. In phase 2.2,
30 participants had at least two of their differences within 5 mmHg and
two participants had no differences within 5 mmHg for systolic blood
pressure, whereas for diastolic blood pressure the number of
participants were 27 and three, respectively. Mean difference for
systolic blood pressure was -0.3 +/- 5.6 mmHg and for diastolic -2.4 +/-
4.8 mmHg.
Conclusions The Microlife WatchBP Home device for self home blood
pressure measurement fulfills all the validation criteria of the
International Protocol and can, therefore, be recommended for clinical
use in the adult population.
