Rehabilitation outcomes of older Chinese patients with different cognitive function in a geriatric day hospital

The relationship between cognitive function and geriatric day hospital (GDH) rehabilitation has not been explored. This study investigated this association in 547 older Chinese patients attended GDH. Cognitive status was assessed by Cantonese version of mini-mental state examination (C-MMSE). Functional independence measure (FIM) upon GDH admission and discharge were measured, with FIM gain = FIM discharge-FIM admission while FIM efficiency = FIM gain/by number of GDH visits. FIM discharge ≥ 90 was defined as satisfactory outcome of rehabilitation. Positive correlation was observed between C-MMSE admission and FIM discharge (p0.001). There were significant differences in the FIM admission and FIM discharge among the three C-MMSE groups, with lower discharge scores in low C-MMSE groups (p0.001). The FIM gain and FIM efficiency during GDH rehabilitation were not different among different C-MMSE groups. C-MMSE admission (p = 0.03) and FIM admission (p0.001) were both positive independent predictors for a satisfactory rehabilitation outcomes (FIM discharge ≥90). Cognitive function was not associated with FIM gain and efficiency. This suggested that selected patients with impaired cognition could still benefit from GDH rehabilitation.
