          Long-term acute care hospitals (LTACHs) have emerged for patients requiring medical care beyond a short stay. Minimal data have been reported on functional outcomes in this setting. The purposes of this study were: (1) to measure the clinical utility of the Functional Status Score for the Intensive Care Unit (FSS-ICU) in an LTACH setting and (2) to explore the association between FSS-ICU score and discharge setting. Data were obtained from 101 patients (median age=70 years, interquartile range [IQR]=61-78; 39% female, 61% male) who were admitted to an LTACH. Participants were categorized into 1 of 5 groups by discharge setting: (1) home (n=14), (2) inpatient rehabilitation facility (n=26), (3) skilled nursing facility (n=23), (4) long-term care/hospice/expired (n=13), or (5) transferred to a short-stay hospital (n=25). Data were prospectively collected from a 38-bed LTACH in the United States over 8 months beginning in September 2010. Functional status was scored using the FSS-ICU within 4 days of admission and every 2 weeks until discharge. The FSS-ICU consists of 5 categories: rolling, supine-to-sit transfers, unsupported sitting, sit-to-stand transfers, and ambulation. Each category was rated from 0 to 7, with a maximum cumulative FSS-ICU score of 35. Cumulative FSS-ICU scores significantly improved from a median (IQR) of 9 (3-17) to 14 (5-24) at discharge. Median (IQR) cumulative discharge FSS-ICU scores were significantly different among the discharge categories: home=28 (22-32), inpatient rehabilitation facility=21 (15-24), skilled nursing facility=14 (8-21), long-term care/hospice/expired=5 (0-11), and transfer to a short-stay hospital=4 (0-7). Patients receiving therapy at an LTACH demonstrate significant improvements from admission to discharge using the FSS-ICU. This outcome tool discriminates among discharge settings and successfully documents functional improvements of patients in an LTACH setting.
