FIM scores at admission of 13 points (total assistance level) and those having a score of 40 points (moderate assistance level). In other words, in conventional methods [4][5][6][7][8][9][10][11][12], whether or not FIM score at discharge or FIM gain becomes greater than the fixed score depends on the FIM scores at admission, rather than the factors such as the amount of training.In this study, a logistic regression analysis was performed on data of patients with stroke hospitalized in a convalescent rehabilitation ward in Japan [14] with FIM at discharge (0 or 1) as the objective variable. We compared the following two methods: a conventional method that sets FIM scores at discharge of 80 points or above as a favorable outcome and a new method that stratifies FIM scores at admission into seven groups, and the median value or above of FIM scores at discharge in each group is set as a favorable outcome. The purpose of this study was to show that the new method can evaluate the factors influencing FIM improvement without being affected by FIM scores at admission.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
