February 1, 1999Blood Pressure Monitoring
The International Database of Self-Recorded Blood Pressures in normotensive and untreated hypertensive subjects
Why the study?
What are the operational thresholds for self-recorded blood pressure compared to conventional blood pressure in untreated subjects?
Population
4,668 untreated subjects pooled from 13 research groups
Comparison
Self-recorded blood pressure (SRBP) measurement vs Conventional blood pressure (CBP) measurement
Design
Meta-analysis

Implication
Supports self-recorded BP thresholds to refine hypertension diagnosis and reduce overdiagnosis; extends meta-analytic evidence for home monitoring in untreated patients.
Structured PICO
What are the operational thresholds for self-recorded blood pressure compared to conventional blood pressure in untreated subjects?
P
Population
4,668 untreated subjects (2,401 normotensive, 494 borderline hypertensive, and 1,773 definitely hypertensive) pooled from 13 research groups
I
Intervention
Self-recorded blood pressure (SRBP) measurement
C
Comparator
Conventional blood pressure (CBP) measurement
O
Outcome
Operational threshold for SRBP and proportion of CBP-diagnosed hypertensive subjects with SRBP within the normotensive rangesurrogate
A mean self-recorded blood pressure above 137/85 mmHg may be considered hypertensive, though a significant proportion of patients diagnosed by conventional measurement fall below these thresholds.
