Kiosk devices for unsupervised self-measurement of blood pressure (BP) are being used in public spaces and healthcare settings in several countries. This statement by the European Society of Hypertension (ESH) Working Group on BP Monitoring and Cardiovascular Variability provides a review of the published evidence on kiosk BP devices and consensus recommendations for their requirements and clinical use. A systematic literature search identified 54 relevant studies. Kiosk BP measurements appeared to be close to office BP [mean difference systolic 0.2 mmHg (95% confidence intervals -1.3 to 1.8); diastolic -0.4 mmHg (-3.5 to 2.7)], and higher than daytime ambulatory and home BP [mean difference 6.0 mmHg (1.6-10.4)/5.0 (2-8) and 8.1 mmHg (-2.6 to 18.9)/0.2 (-9.6 to 10.0), respectively]. Randomized or observational studies using kiosk BP measurements for hypertension screening or for assessing hypertension control were also included, as well as studies investigating users' and healthcare professionals' opinions, acceptability, and perspectives regarding kiosk BP measurements, and validation studies of kiosk BP devices. These studies had considerable heterogeneity in design, setting, methodology, measurement protocol, and sample size. Thus, at present, the clinical utility of kiosk BP measurements is uncertain. This ESH consensus statement acknowledges the potential of kiosk BP measurement as an emerging method for unsupervised self-measurement in the context of opportunistic screening for hypertension in apparently healthy people and the long-term monitoring of people with diagnosed hypertension. Requirements for the design, validation, function, and use of kiosk BP monitors are provided, together with the pending research questions on their optimal implementation in clinical practice.
