Is a cuffless blood pressure device feasible, reproducible, and user-friendly for ambulatory systolic blood pressure measurement in patients with hypertension?
A cuffless blood pressure device demonstrated good intrauser reproducibility and high user-friendliness, suggesting it is a feasible alternative for frequent home blood pressure monitoring in hypertensive patients.
Effect estimate: R=0.86

BACKGROUND: Frequent home blood pressure (BP) measurements result in a better estimation of the true BP. However, traditional cuff-based BP measurements are troublesome for patients. OBJECTIVE: This study aimed to evaluate the feasibility of a cuffless device for ambulatory systolic blood pressure (SBP) measurement. METHODS: This was a mixed method feasibility study in patients with hypertension. Performance of ambulatory SBPs with the device was analyzed quantitatively by intrauser reproducibility and comparability to a classic home BP monitor. Correct use by the patients was checked with video, and user-friendliness was assessed using a validated questionnaire, the System Usability Scale (SUS). Patient experiences were assessed using qualitative interviews. RESULTS: A total of 1020 SBP measurements were performed using the Checkme monitor in 11 patients with hypertension. Duplicate SBPs showed a high intrauser correlation (R=0.86, P<.001). SBPs measured by the Checkme monitor did not correlate well with those of the different home monitors (R=0.47, P=.007). However, the mean SBPs measured by the Checkme and home monitors over the 3-week follow-up were strongly correlated (R=0.75, P=.008). In addition, 36.4% (n=4) of the participants performed the Checkme measurements without any mistakes. The mean SUS score was 86.4 (SD 8.3). The most important facilitator was the ease of using the Checkme monitor. Most important barriers included the absence of diastolic BP and the incidental difficulties in obtaining an SBP result. CONCLUSIONS: Given the good intrauser reproducibility, user-friendliness, and patient experience, all of which facilitate patients to perform frequent measurements, cuffless BP monitoring may change the way patients measure their BP at home in the context of ambulant hypertension management.
Ogink et al. (Mon,) conducted a observational in Hypertension (n=11). Checkme Pro Health Monitor vs. Conventional home blood pressure monitor was evaluated on Intrauser correlation of duplicate systolic blood pressure measurements (R=0.86, p=<0.001). The Checkme cuffless blood pressure monitor demonstrated high intrauser correlation for duplicate systolic blood pressure measurements (R=0.86) and strong correlation with mean home monitor readings over 3 weeks (R=0.75).
