“…Such difficulties might be partially attributable to the observed association of cognitive impairment with poor admission and discharge function in older adults admitted to inpatient rehabilitation services (Fitz & Teri, 1994;Musicco, Emberti, Nappi, & Caltagirone, 2003;Resnick & Daly, 1998;Sahadevan, Lim, & Choo, 1999). However, the meaning of such an association has been increasingly challenged because of an observed lack of association between cognitive impairment and functional gain, that is, the change in function from admission to discharge as an outcome of rehabilitation services (Barnes, 1984;Baztán, Forcano, González, & Ruipérrez, 2003;Diamond, Felsenthal, Macciocchi, Butler, & Lally-Cassady, 1996;Goldstein, Strasser, Woodard, & Roberts, 1997;Jackson, 1984;Morris et al, 1999;Ruchinskas, Singer, & Repetz, 2000;Sahadevan et al, 1999;Tappen, 1994). Other than functional gain, the effect of cognitive impairment on other rehabilitation outcomes (e.g., rehabilitation efficiency, length of stay (LOS), and discharge location) is largely inconclusive because of the scarcity of studies and variation in measurements.…”
