Prevalence of frailty and frailty outcomes within the inpatient rehabilitation setting: use of routinely collected electronic health information.

Aims: Frailty within the older adult rehabilitation population is relatively under-explored. We aimed to derive a frailty index (FI) from electronic routinely collected data to determine frailty prevalence, and to assess its ability to predict adverse outcomes in the rehabilitation setting.

Methods: A FI was derived and retrospectively applied to electronically recorded health information of older adults admitted for inpatient rehabilitation.
