Relationships between initial motor assessment scale scores and length of stay, mobility at discharge and discharge destination after stroke
Purpose: This retrospective audit explored the relationships between Motor Assessment Scale (MAS) scores on admission and patient outcomes including length of stay (LOS), mobility at discharge and discharge destination from an Australian stroke unit.
Methods: The dataset included 239 individuals admitted to a stroke rehabilitation unit between June 2001 and January 2007, Associations between variables (admission and discharge scores for total MAS and MAS mobility items 1-5, LOS, discharge destination and mobility at discharge) were examined. Regression analyses were used to assess the ability of the MAS to predict discharge destination and mobility status at discharge and the influence of other factors such as age, type and side of stroke and gender.
Results: Poor mobility on admission was significantly associated with longer LOS (r =-,716, p<0,001 for mobility items). The likelihood of discharge to an institution increased with age (p=0,009) and with lower MAS on admission (p<0,001). Likewise, only age and total MAS admission scores were significantly related to the likelihood of walking independently on discharge. The regression model correctly predicted a greater percentage of those discharged home (with or without support) (86,4%) compared to discharge to an institution (51,4%).
Conclusions: This study provides further evidence for the utility of MAS admission scores to predict some outcomes in an older cohort of stroke survivors.
