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 d emented patients with hip fracture. Design Preplanned subanalysis of randomised intervention study. Setting-Jyvaskyla Central Hospital, Finland, Participants 243 independently living patients aged 65 years or older admit ted to hospital with hip fracture. Intervention After surgery patients in the intervention group (n = 120) wer e referred to the geriatric ward whereas those in the control group were di scharged to local hospitals. Main outcome measures Length of hospital stay, mortality, and place of resi dence three months and one year after surgery for hip fracture. Results The median length of hospital stay of hip fracture patients with mo derate 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 th e control group (n = 42, P = 0.002). Three months after the operation, in t he intervention group 91% (32) of the patients with mild dementia and 63% ( 15) of the patients with moderate dementia were living independently. Ln th e 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 st ate examination scores. Conclusions Hip fracture patients with mild or moderate dementia can often return to the community if they are provided with active geriatric rehabili tation.
