Performance of an automated blood pressure measurement device in a stroke rehabilitation unit.

Valid blood pressure (BP) measurements are needed in post-stroke rehabilitation hospital units for the management of hypertension. Automated devices could be used to improve on usual care BP measurement. However, more information is needed about the performance of these devices in such a context.
This prospective nonrandomized study was performed in stroke patients with hypertension hospitalized in a stroke rehabilitation unit. Two in-hospital BP assessment strategies were compared: usual care BP and in-hospital automated office BP (AOBP) standardized measurements. In-office AOBP and ambulatory BP monitoring (ABPM) were also performed on these patients. The main outcome was SBP. Study follow-up was until discharge, up to a maximum of 4 weeks.
Sixty-two patients with stroke hospitalized in a rehabilitation unit were included. Usual care BP was 130 ± 12/79 ± 9 mmHg and differed from an in-hospital AOBP of 117 ± 14/75 ± 12 mmHg (P < 0.001/P < 0.001). In-hospital and in-office AOBP measurements did not differ. Twenty percent of patients reached SBP therapeutic goals according to in-hospital AOBP but not according to usual care BP measurements.
This study shows that in a post-stroke rehabilitation unit, standardized in-hospital AOBP estimates are on average much lower than the usual care BP correlates and similar to the in-office AOBP estimates. In-hospital AOBP devices in a stroke rehabilitation unit could add important information for the management of hypertension.
