OBJECTIVES: This study examines the effects of depression and cognitive impairment in elderly hip fracture patients receiving inpatient rehabilitation. Our goal was to determine whether any association of depression and cognitive impairment with rehabilitation outcome is accounted for by more immediate effects of these variables on rehabilitation participation.
METHODS: We measured depression using the Hamilton Rating Scale for Depression (Ham-D), cognition using the Mini Mental State Examination (MMSE), and rehabilitation outcomes using the motor scale of the Functional Independence Measure (motor FIM) in a prospective observational study of 57 elderly rehabilitation hospital patients admitted to a university-affiliated, freestanding rehabilitation hospital with primary diagnosis of hip fracture. We also assessed rehabilitation participation, to determine whether this accounted for (mediated) any relationship of depression and cognitive impairment with rehabilitation outcome.
RESULTS: Baseline Ham-D and MMSE scores were correlated with motor FIM efficiency-those with higher depressive symptoms had lower efficiency (r = -0.44, p < 0.001); similarly, those with more cognitive impairment had lower motor FIM efficiency (r = 0.52, p < 0.001). Rehabilitation participation was a mediator of this association: greater depressive symptoms and cognitive impairment predicted poorer rehabilitation participation which, in turn, predicted lower motor FIM efficiency. Ham-D and MMSE scores were predictors of discharge location: subjects with high depressive symptoms and greater cognitive impairment were more likely to go to a nursing home or personal care home upon discharge.
CONCLUSIONS: Depression and cognitive impairment are predictive of negative outcomes in elderly patients' rehabilitation from hip fracture. This effect is mediated by rehabilitation participation, and ratings in this area may serve as a potentially useful clinical and research tool for the rehabilitation environment.
