Why the study?

Does blood pressure measurement using an automated device with the patient alone reduce the white coat effect compared to physician-measured blood pressure?

Population

Patients undergoing blood pressure measurement

Comparison

Blood pressure measurement using an automated BP… vs Blood pressure taken by the patient's family…

Design

Implication

Automated unattended BP yields lower readings than physicians; hypothesis-generating for white coat mitigation, needs prospective validation before practice change.

Key Points

To evaluate whether physician presence triggers the white coat effect by comparing blood pressure readings from an automated device taken with the patient alone against standard clinical measurements.
Measured blood pressure with an automated recording device (BpTRU) while the patient was alone in an ambulatory blood pressure (ABP) research unit.
Compared automated readings to blood pressure measurements taken by family physicians, a hypertension specialist, a trained research technician, and mean awake ABP monitoring.
Blood pressure readings (mean ± SEM) were lower with the automated device (155 ± 5/88 ± 2 mm Hg) than with the family physician (166 ± 4/89 ± 3 mm Hg) and the hypertension specialist (174 ± 5/92 ± 2 mm Hg; P < .001).
Trained technician readings (158 ± 4/90 ± 2 mm Hg) were similar to automated values, whereas mean awake ABP was significantly lower than all four clinical measurement types (P < 0.01).

Structured PICO

Does blood pressure measurement using an automated device with the patient alone reduce the white coat effect compared to physician-measured blood pressure?

Population

Patients undergoing blood pressure measurement

Intervention

Blood pressure measurement using an automated BP recording device (BpTRU) with the patient alone in the examining room

Comparator

Blood pressure taken by the patient's family physician, on the first visit to a hypertension specialist, by a trained research technician, and mean awake ambulatory BP (ABP)

Outcome

Blood pressure readings (mm Hg)surrogate

Automated blood pressure recording with the patient alone can partly eliminate the white coat effect associated with physician-measured readings, providing a more accurate estimate of blood pressure status.
