Why the study?

Does wrist oscillometric blood pressure measurement accurately reflect conventional upper arm sphygmomanometry in cardiology outpatients?

Population

255 consecutive patients admitted to a cardiology outpatient clinic, mean age 65 +/- 13 years, 149 males.

Comparison

Oscillometric blood pressure measurement at the… vs Conventional mercury sphygmomanometer applied at…

Implication

Wrist devices overestimate arm BP in outpatients; leaves open their reliability for clinical decisions pending prospective validation.

Structured PICO

Does wrist oscillometric blood pressure measurement accurately reflect conventional upper arm sphygmomanometry in cardiology outpatients?

P
Population
255 consecutive patients admitted to a cardiology outpatient clinic (after excluding 78 from an initial 333), mean age 65 +/- 13 years, 149 males.
I
Intervention
Oscillometric blood pressure measurement at the wrist using the 'Klock' device.
C
Comparator
Conventional mercury sphygmomanometer applied at the upper arm.
O
Outcome
Accuracy of blood pressure readings (mean difference between wrist and upper arm measurements).surrogate

Wrist blood pressure measurement shows low reliability and significant overestimation compared to conventional upper arm sphygmomanometry, limiting its clinical utility.
