A comparative trial of blood pressure monitoring in a self-care kiosk, in office, and with ambulatory blood pressure monitoring

Table 3 Differences between systolic and diastolic BP monitoring performed in office or in a kiosk (N = 117)

Type of BP monitoring	Systolic BP (mm Hg)		P
Type of BP monitoring	Mean (SD)	Mean difference in office – kiosk BP (95% CI)	P
Kiosk^a (reference)	142.2 (13.8)	NA	NA
Nurse-measured^a	138.1 (13.2)	−4.1 (−5.5 to −2.8)	< 0.001
Physician-measured at enrolment^b	143.6 (15.4)	1.4 (−0.8–3.7)	0.215
Type of BP monitoring	Diastolic BP (mm Hg)		P
Type of BP monitoring	Mean (SD)	Mean difference in office – kiosk BP (95% CI)	P
Kiosk (reference)	85.3 (10.2)	NA	NA
Nurse-measured	84.6 (8.9)	−0.7 (−1.9–0.4)	0.205
Physician-measured at enrolment	83.3 (11.1)	−2.1 (−4.0 to −0.2)	0.032

Analyses performed with paired t-tests with kiosk BP as reference.
Abbreviations: ABPM ambulatory blood pressure monitoring, BP blood pressure, CI confidence interval, SD standard deviation
^aMean of four measurements in BP kiosk or nurse-measured, 2 BP measurements each day, before and after ABPM
^bMean of 2 BP measurements in office by a physician at the enrollment visit
