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

Table 2 Differences in mean systolic and diastolic BP and daytime ABPM^a by type of BP monitoring (N = 117)

Type of BP monitoring	Systolic BP (mm Hg)		P
Type of BP monitoring	Mean (SD)	Mean difference in BP daytime ABPM (95% CI)	P
Daytime ABPM (reference)	136.0 (12.9)	NA	NA
Kiosk^b	142.2 (13.8)	6.2 (3.8–8.6)	< 0.001
Nurse measured ^c	138.1 (13.2)	2.0 (−0.2–4.2)	0.071
Physician-measured, at enrollment ^d	143.6 (15.4)	7.6 (4.5–10.2)	< 0.001
Type of BP monitoring	Diastolic BP (mm Hg)		P
Type of BP monitoring	Mean (SD)	Mean difference in BP daytime ABPM (95% CI)	P
Daytime ABPM (reference)	77.4 (9.5)	NA	NA
Kiosk	85.3 (10.2)	7.9 (6.2–9.6)	< 0.001
Nurse-measured	84.6 (8.9)	7.2 (5.9–9.6)	< 0.001
Physician-measured at enrollment	83.3 (11.1)	5.8 (4.1–7.6)	< 0.001

Analyses performed with paired t-test, daytime ABPM reference.
^aDaytime ABPM, mean of ambulatory registrations from 06 A.M. until 22 P.M, every 30 minutes
^b Kiosk for self-directed BP monitoring
^c Nurse-measured: mean of 4 BP measurements, two before and two after ABPM
^dPhysician-measured at enrollment: mean of 2 BP measurements Abbreviations: ABPM ambulatory blood pressure monitoring, BP blood pressure, CI confidence interval, SD standard deviation
