This study observed PAI frequency and duration data for a representative sample (n=75) of hospitalized older adults. Subsequently, they determined the impact of PAIs on clinical and hospital parameters, and the influence of frailty and cognition on these outcome parameters.
PAI dosing was consistent in this sample, commencing after a median of 2 days, with a median of 0.4 PAIs per day. All clinical parameters (balance confidence, ADL indepence, handgrip strength and preferred gait speed) showed significant improvement during hospitalization episodes.
In the unimpaired subgroup, there were significant associations between time to first PAI or total PAI duration and clinical parameters. However, for subgroups with frailty or cognitive impairment, no statistically significant associations between PAI frequency and duration and clinical parameters were observed.
