Background  Timely palliative care in frail older persons remains challenging. Scales to identify older patients at risk of functional decline already exist. However, factors to predict short term mortality in older hospitalized patients are scarce.    Methods  In this prospective study, we recruited patients of 75 years and older at the department of cardiology and geriatrics. The usual gait speed measurement closest to discharge was chosen. We used the risk of dying within 1 year as parameter for starting palliative care. ROC curves were used to determine the best cut-off value of usual gait speed to predict one-year mortality. Time to event analyses were assessed by COX regression.    Results  On the acute geriatric ward ( n  = 60), patients were older and more frail (assessed by Katz and iADL) in comparison to patients on the cardiology ward ( n  = 82); one-year mortality was respectively 27 and 15% ( p  = 0.069). AUC on the acute geriatric ward was 0.748 ( p  = 0.006). The best cut-off value was 0.42 m/s with a sensitivity and specificity of 0.857 and 0.643. Slow walkers died earlier than faster walkers (HR 7.456,  p  = 0.011), after correction for age and sex. On the cardiology ward, AUC was 0.560 ( p  = 0.563); no significant association was found between usual gait speed and survival time.    Conclusions  Usual gait speed may be a valuable prognostic factor to identify patients at risk for one-year mortality on the acute geriatric ward but not on the cardiology ward.
