The FIM™ as a measure of change in function after discharge from inpatient rehabilitation: a Canadian perspective.

Abstract

To examine the FIM™ as an outcome measure at follow-up following discharge from inpatient rehabilitation. Secondary analysis of the National Rehabilitation Reporting System (NRS) data from 13 facilities across Canada that collected follow-up data between 2001 and 2006. The study sample included all NRS records with a hospital length of stay of at least 3 days, for individuals 18 years and older. Outcomes included: mean total, motor and cognitive FIM™ scores at admission, discharge, and follow-up; change in FIM™ scores from admission to discharge and from discharge to follow-up; correlation between FIM™ scores at admission, discharge and follow-up, and predictors of the change in FIM™ scores between discharge and follow-up. The majority of the change in FIM™ scores is seen between admission and discharge with the higher FIM scores maintained, if not increased slightly, between discharge and follow-up. Discharge and follow-up total FIM™ scores are highly correlated indicating that collection of the follow-up FIM™ may not provide additional information that justifies the expense of data collection after a patient has been discharged from inpatient rehabilitation. The use of more appropriate rehabilitation follow-up outcomes needs to be considered.
