Automated office blood pressure measurement yielded a significantly lower prevalence of systolic white-coat hypertension compared to routine manual blood pressure (7.3% vs 22.1%, P=0.005).

Does automated office blood pressure (AOBP) measurement accurately diagnose hypertension and reduce white-coat hypertension misdiagnosis compared to routine manual BP and 24-h ABPM in untreated patients?
Automated office blood pressure measurement provides readings similar to awake ambulatory blood pressure and significantly reduces the misdiagnosis of white-coat hypertension compared to routine manual office blood pressure.

OBJECTIVE: To validate an algorithm for the interpretation of automated office blood pressure (AOBP) measurement based upon data from untreated patients referred by physicians in the community for 24-h ambulatory blood pressure monitoring (ABPM). METHODS: An algorithm for interpreting AOBP readings was developed taking into account the previously documented equivalence of AOBP and mean awake ambulatory BP (ABP; mmHg), which were each classified as optimum BP (or=140/90). This classification was applied to data derived from 254 untreated patients undergoing 24-h ABPM, AOBP and routine manual BP taken at the patient's own family physician's office. RESULTS: The mean awake ABP (135.3 +/- 12.4/81.0 +/- 10.2) was similar to the mean AOBP (132.6 +/- 17.4/80.0 +/- 11.1) with both values being significantly (P < 0.001) lower than the routine manual BP (149.7 +/- 15.2/89.3 +/- 9.5). Of the 69 patients with a systolic AOBP at least 140, only five (7.3%) exhibited white-coat hypertension with a normal mean awake ambulatory systolic BP less than 130. Similarly, of the 47 patients with a diastolic AOBP at least 90, none had optimum BP (diastolic BP < 80 mmHg on ABPM). White-coat hypertension was significantly (P = 0.005/P = 0.006) more prevalent for systolic/diastolic BP (22.1%/13.4%) when routine, manual BP readings were analysed. CONCLUSION: In contrast to routine manual office BP, a diagnosis of hypertension by AOBP is unlikely to be associated with an optimum awake ABP.
Martin G. Myers (Tue,) conducted a cross-sectional in Hypertension (n=254). Automated office blood pressure (AOBP) measurement vs. Routine manual blood pressure measurement was evaluated on Prevalence of systolic white-coat hypertension (p=0.005). Automated office blood pressure measurement yielded a significantly lower prevalence of systolic white-coat hypertension compared to routine manual blood pressure (7.3% vs 22.1%, P=0.005).
