In conclusion , decrease in muscle strength and muscle mass in older patients is dependent on the type of admission .
HIGHLIGHTSPhysical inactivity during hospitalization is associated with detrimental outcome .Muscle strength and muscle mass decreased in electively admitted older patients .Muscle strength and muscle mass did not change in acutely admitted older patients
ABSTRACT Hospitalization may induce a decrease of muscle strength and muscle mass in older patients due to physical inactivity , malnutrition and diseases , negatively affecting health outcome .
We aim ed to examine the literature on change in muscle strength and muscle mass in older patients during hospitalization .
The underrecognized epidemic of low mobility during hospitalization of older adults.
OBJECTIVES To examine the proportion of time spent in three levels of mobility ( lying , sitting , and st and ing or walking ) by a cohort of hospitalized older veterans as measured by vali date d wireless accelerometers . DESIGN A prospect i ve , observational cohort study . SETTING One hundred fifty-bed Department of Veterans Affairs hospital . PARTICIPANTS Forty-five hospitalized medical patients , aged 65 and older who were not delirious , did not have dementia , and were able to walk in the 2 weeks before admission were eligible . MEASUREMENTS Wireless accelerometers were attached to the thigh and ankle of patients for the first 7 days after admission or until hospital discharge , whichever came first . The mean proportion of time spent lying , sitting , and st and ing or walking  was determined for each hour after hospital admission using a previously vali date d algorithm . RESULTS Forty-five male patients ( mean age 74.2 ) with a mean length of stay of 5.1 days generated 2,592 one-hour periods of data . A baseline functional assessment indicated that 35 ( 77.8 % ) study patients were willing and able to walk a short distance independently . No patient remained in bed the entire measured hospital stay , but on average , 83 % of the measured hospital stay was spent lying in bed . The average amount of time that any one individual spent st and ing or walking ranged from a low of 0.2 % to a high of 21 % , with a median of 3 % , or 43 minutes per day . CONCLUSION This is the first study to continuously monitor mobility levels early during a hospital stay . On average , older hospitalized patients spent most of their time lying in bed , despite an ability to walk independently
