Key result
Blood pressure response to orthostatism showed significant within-day variability (p < .05) and poor reproducibility for diagnosing orthostatic hypotension (kappa < 0.47) in elderly patients.

Is the diagnosis of orthostatic hypotension reproducible within-day and day-to-day in elderly patients?
Population
53 consecutive elderly patients of an intermediate care geriatric ward
Design

Single orthostatic BP measurements may be unreliable in elderly patients; leaves open optimal diagnostic protocols for research.
Observational (n=53)
Is the diagnosis of orthostatic hypotension reproducible within-day and day-to-day in elderly patients?
Effect estimate: kappa < 0.47
p-value: p=< .05
The diagnosis of orthostatic hypotension based on conventional criteria exhibits poor within-day and day-to-day reproducibility in elderly patients, suggesting single measurements may be insufficient.
Belmin et al. (2000) conducted an observational in Orthostatic hypotension (n=53). Orthostatism was evaluated on Within-day and day-to-day variability of systolic BP response and reproducibility of OH diagnosis (kappa < 0.47, p=< .05). Blood pressure response to orthostatism showed significant within-day variability (p < .05) and poor reproducibility for diagnosing orthostatic hypotension (kappa < 0.47) in elderly patients.
