Why the study?

Does wrist blood pressure measurement accurately reflect upper arm blood pressure and avoid 'hidden undercuffing' in obese patients?

Population

261 consecutive patients at an outpatient hypertension clinic, mean age 62.1, 51.3% male, obese.

Comparison

Wrist blood pressure measurement using an… vs Upper arm blood pressure measurement using…

Design

Cross-sectional, Randomized starting site for alternating measurements

Discussion

Member takes

Implication

Wrist BP overestimates arm values with poor concordance; leaves open its role in obese patients pending prospective validation.

Structured PICO

Does wrist blood pressure measurement accurately reflect upper arm blood pressure and avoid 'hidden undercuffing' in obese patients?

Population

261 consecutive patients at an outpatient hypertension clinic, mean age 62.1, 51.3% male, obese (mean BMI 30.6 kg/m2).

Intervention

Wrist blood pressure measurement using an oscillometric wrist cuff (HoMedics BPW-200)

Comparator

Upper arm blood pressure measurement using auscultation with an appropriate-sized cuff

Outcome

Difference between mean systolic and diastolic blood pressures measured at the arm and wristsurrogate

Wrist blood pressure measurements show poor concordance with standard upper arm measurements, even in obese patients, and should not be routinely substituted in clinical practice.

Limitations

Did not compare with intra-arterial BP readings
Used only one specific wrist monitor model
