A study by UTMB researchers Steve R. Fisher, Yong-fang Kuo, James E. Graham, Kenneth J. Ottenbacher and Glenn V. Ostir examined the association between ambulation and length of stay in geriatric patients admitted for acute illnesses. They hypothesized that increase in ambulation within the 48 hours after admission would predict LOS after adjusting for risk factors. Patients 65 years or older admitted to an Acute Care for Elders unit were studied. “Patients who increased their walking by at least 600 steps from the first to second 24-hour day were discharged approximately two days earlier than those who did not. Results suggest accelerometers may be useful in creating clinical thresholds for ambulation in hospitalized persons. These thresholds may not be excessively high; 600 steps correspond to approximately 12 minutes of slow walking.
