Randomised, clinically controlled trial of intensive geriatric rehabilitation in patients with hip fracture: subgroup analysis of patients with dementia

OBJECTIVE: To evaluate the effect of intensive geriatric rehabilitation on demented patients with hip fracture. DESIGN: Preplanned subanalysis of randomised intervention study. SETTTING: Jyväskylä Central Hospital, Finland. PARTICIPANTS: 243 independently living patients aged 65 years or older admitted to hospital with hip fracture. INTERVENTION: After surgery patients in the intervention group (n=120) were referred to the geriatric ward whereas those in the control group were discharged to local hospitals. MAIN OUTCOME MEASURES: Length of hospital stay, mortality, and place of residence three months and one year after surgery for hip fracture. RESULTS: The median length of hospital stay of hip fracture patients with moderate dementia (mini mental state examination score 12-17) was 47 days in the intervention group (n=24) and 147 days in the control group (n=12, P=0.04). The corresponding figures for patients with mild dementia (score 18-23) were 29 days in the intervention group (n=35) and 46.5 days in the control group (n=42, P=0.002). Three months after the operation, in the intervention group 91% (32) of the patients with mild dementia and 63% (15) of the patients with moderate dementia were living independently. In the control group, the corresponding figures were 67% (28) and 17% (2). There were no significant differences in mortality or in the lengths of hospital stay of severely demented patients and patients with normal mini mental state examination scores. CONCLUSIONS: Hip fracture patients with mild or moderate dementia can often return to the community if they are provided with active geriatric rehabilitation.
