Predictors of discharge to acute care after inpatient rehabilitation in severely affected stroke patients

They still are just using secondary effects rather than primary ones like penumbra damage and dead brain area.

Abstract: Study identified predictors of discharge to acute care after inpatient rehabilitation in severely affected stroke patients. Participants included 223 of the most severely affected stroke patients: 86 were discharged to acute care and 137 were discharged to the community after inpatient medical rehabilitation. The variables examined were Functional Independence Measure (FIM) ratings, co-morbid medical conditions, and four groups of stroke-related neurologic deficits (hemiparesis, dysphagia, language deficits, and other stroke-related neurologic deficits). Results showed there were no significant demographic differences between those discharged to the acute care hospital and those discharged to the community. There was a difference in admission FIM ratings, whereby patients discharged to acute care were significantly lower on admission motor and cognitive function than were patients discharged to the community. After controlling for 19 groups of co-morbid medical conditions and 4 groups of stroke-related neurologic deficits, there was no significant difference between patients being discharged to an acute care hospital and those discharged to the community. The only variable predictive of discharge to the acute care hospital from an inpatient rehabilitation facility was function at admission, mainly the admission FIM motor rating.
