Abstract

Introduction: Out-of-office blood pressure (BP) monitoring is increasingly valuable in the diagnosis and management of hypertension. With advances in wearable BP technologies, the ability to gain insight into BP outside of traditional centers of care has expanded greatly.

Methods: Here we explore the usability of a novel, wrist-worn BP cuff monitor for out-of-office data collection with participants following digital cues rather than in-person instruction. Transmitted measurements were used to evaluate BP variation with the time of day and day of week, BP variation with mood, and orthostatic measurements.

Results: Fifty participants, with a mean age of 44.5 years, were enrolled and received the BP monitor. 82% of the participants transmitted data via the smartphone application, and the median wear time of the device during the 4-week study was 11 days (IQR 8-17).

Discussion: This prospective digital pilot study illustrates the usability of wearable oscillometric BP technology combined with digital cues via a smartphone application to obtain complex out-of-office BP measurements, including orthostatic vital signs and BP associated with emotion. 25 out of 32 participants who attempted orthostatic vital signs based on in-app instruction were able to do so correctly, while 24 participants transmitted BP readings associated with emotion, with a significant difference in BP noted between calm and stressed emotional states.

Blood pressure variation with day of the week. Average daily blood pressure was calculated from the 37 individuals who transmitted at least 10 total measurements. Wednesday was associated with the highest average systolic and diastolic BP while Saturday was associated with the lowest average systolic and diastolic BP. Error bars represent standard error of the mean (SEM).

Bp associated with emotion. * = p < 0.005. The above box and whisker plots represent the median, interquartile range and standard deviation of the difference between participants average daily BP and BP associated with emotion, with the blue plot representing calm and the red plot representing stressed. The blue plus sign (+) represents the mean difference between participants average daily BP and BP associated with calm (−4.6 mmHg), while the red plus sign (+) represents the mean difference between participants average daily BP and BP associated with stressed (+5.0 mmHg). The associated mean differences were statistically significant as indicated above.
