We have read with interest the study by Johnson et al1 on the reliability of self-reported blood pressure (BP) measurements. The authors studied 29 subjects and found that 68% of subjects' reports of recorded systolic BP (SBP) and diastolic BP (DBP) measurements were identical to electronically stored results, although a significant percentage of recorded BP readings differed from the stored BP, especially in cases of elevated BP (P<.001). The authors concluded that if a disparity is perceived between home and office readings, it is necessary to validate the accuracy of the monitor and consider "white-coat" hypertension and false reporting.
