Should the measurement of blood pressure in the office be redefined?:

Clinician accountability in a primary care clinic time-interval blood pressure measurements study: Practice implications

BACKGROUND

Accurate blood pressure measurements (BPM) are important, as clinicians are tasked daily with using such measurements to make clinical diagnoses and patient care judgments. Research studies and controlled trials hold such measurements to a higher standard than everyday clinical practice.

OBJECTIVE

The aim of this study was to evaluate difference in BPM outcomes of individuals in a clinic setting when clinicians collect BPM as usual vs BPM after 5- (USPSTF recommendation) and 10- minute (study unique intervention) timed rest interval.

METHODS

A repeated-measures design was used to examine individual BPMs at the intervals of baseline, after a 5-minute rest interval post-baseline, and after a 10-minute rest interval post-baseline. Results Pairwise comparisons indicated that baseline SBP was the highest when compared to SBP measured at both 5- and 10-minutes post-baseline. SBP measured at 5-minutes was also significantly higher compared to SBP collected at 10-minutes post-baseline (ps < .05). For DBP, the repeated-measures ANOVA indicated that there was no significant difference across BPMs, F(2,198) = 1.25, p = .29.

CONCLUSIONS

Results from this study revealed that implementing a 5-minute rest interval before BPMs are taken in a clinic setting produces a "clinically observable" reduction in the overall mean systolic BPs as seen at both 5- and 10-minute BPM intervals. It is important for all healthcare clinicians to recognize the importance of accurate BPM and the need to encourage better regulated BPM standard in everyday practice.
