Walking speed is a powerful predictor of mortality and adverse health consequences (e.g. fall or hospitalization) in older adults. Knowledge of individuals' walking speed can provide unique insight into current physical function and need for healthcare services. Furthermore, walking speed is a modifiable risk factor such that early recognition of physical function decline allows for appropriate and timely intervention prior to the occurrence of adverse health events. Therefore, this proposal seeks to implement routine measures of walking speed into VHA primary care as a 'vital sign' to routinely monitor Veteran physical function and help guide provider referrals.
