Factors related to the mobility of hospitalized older adults: A prospective cohort study.

A low ambulation rate is common even among acutely ill hospitalized older adults. This prospective observational study conducted among 769 older adults (≥70) hospitalized in acute-care units tested the relationship of satisfaction with hospital environment, sleep-medication consumption, and in-hospital caloric intake to mobility levels during hospitalization on 3 consecutive hospitalization days. Approximately 20% of the patients did not walk, 30% walked only in their room, and 50% mobilized outside their room. A multinomial-logistic regression, controlling for potential intervening factors, showed that sleep-medication avoidance (AOR = 1.99; p < 0.01) and higher caloric intake (AOR = 9.69; p < 0.001) differentiated patients walking outside the room from non-walking patients. Satisfaction with the physical environment was lower in the non-mobile group than in the other two. Results suggest that hospital environment, sleep-medication consumption, and caloric intake during hospitalization need to be addressed in attempts to improve in-hospital mobility in older adults.
