Does mental estimation of home blood pressure means from paper charts accurately reflect electronically calculated means in hypertensive patients?
Mental calculation of home blood pressure means from paper charts can lead to diagnostic errors in 15% of cases, highlighting the utility of blood pressure devices with automated analytical capacities.
Ouattara et al. (2018) conducted a cross-sectional in Hypertension (n=109). Mental calculation of home blood pressure means vs. Electronic calculation was evaluated on Diagnostic performance (determination of therapeutic systolic and diastolic BP goals attained or not) and BP means. Mental calculation of home blood pressure means from paper charts resulted in diagnostic disagreement in 15% of cases compared to electronic calculation.
