Objective: The objective of the present study was to
determine the differences in FIM improvement
(corrected FIM-M effectiveness) in proximal femoral
fracture patients due to age.
Methods: The subjects were 886 proximal femoral
fracture patients. For the formula, Corrected FIM-M
effectiveness = FIM-M gain / (A - FIM-M at admission),
we determined values of A that would yield a mean
FIM-M effectiveness of roughly 0.65. We divided the
subjects into seven groups each covering an age range
of five-year increments, and we determined the mean
corrected FIM-M effectiveness for each group.
Results: For FIM-M of 13-18, 19-24, 25-30, and 31-
90 points at admission, the value of A was 47, 70, 85, and
91 points, respectively. Corrected FIM-M effectiveness
declined with advancing age, especially above 80 years
old.
Conclusion: Mean FIM improvement in proximal
femoral fracture patients begins to decline at age 80,
while it was reported to be at age 70 in stroke patients.
