Differences in automated and manual blood pressure measurement in hospitalized psychiatric patients.

Few studies have been conducted recently with noncritically ill patients evaluating commonly used automated blood pressure (BP) devices. The purpose of this study was to compare BP values obtained using a manual sphygmomanometer versus an oscillometric automated electronic BP device on an acute care psychiatry unit. A method-comparison design was used, and data were analyzed using the Bland-Altman method.
