[Applicability and limitations of physical performance tests for frailty screening on discharge from an intermediate...

Frailty screening can be performed with different tools and in multiple settings. Among the different evaluation systems, gait speed (GS) and Timed Up-and-Go (TUG) are postulated as simple and easy to apply systems. There are few data on the prevalence of frailty in intermediate care centre inpatients.

Descriptive study to determine the applicability of GS and TUG as frailty screening tools in an intermediate care hospital, as well as an estimate of frailty prevalence at discharge. Frailty was considered when GS<1m/s and / or TUG>12seconds. The study included all patients attending the rehabilitation unit of the centre throughout 2015.

A total of 909 patients were included (mean age of 80.12 years). Only 205 (22.6%) were able to perform GS and TUG at discharge from the rehabilitation unit. Frailty prevalence for this group was between 89.8% (GS) and 92.2% (TUG), with no statistical differences between both tools (P=.25).

The applicability of GS and TUG for frailty screening in intermediate care hospitals is limited. Despite this, the results obtained suggest a high prevalence of frailty. More studies will be necessary to corroborate this data.
