The degree and timing of orthostatic blood pressure changes in relation to falls in nursing home residents

Abstract

Orthostatic hypotension (OH) is traditionally defined as a decline in systolic or diastolic blood pressure of >20 or >10 mm Hg, respectively, after 1 or 3 minutes of upright posture. OH is common in the elderly, but has not been consistently demonstrated to be an independent risk factor for falls in nursing home residents. Previous studies have used the standard definition of OH in assessing fall risk. No study has sought to determine if the timing of postural changes in blood pressure adds prognostic value; if changes in systolic, diastolic, or mean blood pressure are equivalent in predicting subsequent falls; and what degree of decline in blood pressure has the best predictive value. We sought to define the timing and degree of orthostatic changes in blood pressure in a cohort of elderly nursing home residents during active standing and to explore the relationship to subsequent falls to test the hypothesis that orthostatic changes in blood pressure with noninvasive beat-to-beat technology would predict falls in nursing home residents better than the standard definition of OH. One hundred eleven elderly (88 +/- 7 years) residents of a long-term care facility had measurement of orthostatic blood pressure changes during active s...Continue Reading
