Low dose mobility and functional status outcomes in hospitalized older general medicine patients

Emerging evidence suggests hospitalized older adults should walk at least 20-minutes daily to minimize functional decline. A single-institution case study conducted in a tertiary-referral centre in Melbourne, Australia, aimed to examine functional change and describe characteristics of older patients' in-hospital mobility. From 526 older patients vulnerable to functional decline, a sample of 41 patients (Mean age = 83.6, SD = 6.1 years) participated in 6-hour naturalistic observations. Functional change was measured at 2-weeks preadmission, admission and discharge with the revised Measurement System of Functional Autonomy (SMAF). Nearly 25% (n = 10) of observed patients functionally declined between preadmission and discharge and five patients died (12.2%). Thirty-two patients (78%) mobilized in 133 episodes accounting for 3.1% of the 246-hours observed. A daily walking-exercise dose equivalent to 20-min was associated with less functional decline in older adults with moderate to high walking capability supporting the effectiveness of this daily walking-exercise dose in minimizing functional decline.
