Impact of Frailty on Gait Speed Improvements in Home Health after Hospital Discharge: Secondary Analysis of Two...

More than half of older adults are frail or prefrail in the United States, and hospital-associated deconditioning likely increases this risk. However, the impact of frailty on potential functional improvements after hospital discharge is poorly understood. We sought to identify the influence of baseline frailty on gait speed change in older adults receiving home health physical therapy (PT) after hospital discharge. The severity of frailty was assessed using Cardiovascular Health Study frailty criteria (weakness, slowness, weight loss, physical inactivity, and exhaustion). Gait speed was measured at baseline and 60-days post-hospital discharge. Upon admission to home health rehabilitation services, half of older adults (total N=250) were considered frail, with slowness (90%) and weakness (75%) being the most common characteristics. Older adults, whether pre-frail or frail, demonstrated similar and clinically meaningful improvements in gait speed after receiving home health rehabilitation for 60 days following hospital discharge. These results suggest that clinicians caring for older adults in the hospital can counsel both pre-frail and frail patients that, with home health rehabilitation, clinically significant improvements in function can be expected over the 2 months following discharge. Furthermore, we observed encouraging gait speed improvement with physical therapy following hospitalization in older adults. Results can inform anticipatory guidance on hospital discharge.
