OBJECTIVES: Few studies describe the trajectories of cognitive function for hip-fracture patients following hospital discharge and the treatment effects of interdisciplinary intervention on cognitive outcomes. The purpose of this study was to explore the 2-year postoperative trajectory for cognitive function of older hip-fracture patients and cognitive effects of an interdisciplinary intervention.
METHODS: Of 160 subjects randomly assigned to groups, 29 (35.8%) in the control group (n = 81) and 30 (38.0%) in the intervention group (n = 79) were cognitively impaired at admission. The intervention group received geriatric consultation, continuous rehabilitation, and discharge planning. Subjects' cognitive function was measured using the mini mental state examination Taiwan version at admission, 6, 12, 18, and 24 months after discharge and analyzed using hierarchical generalized linear models.
RESULTS: Patients who received the intervention program had 75% less likelihood of being cognitively impaired 6 months following discharge than those who received routine care (odds ratio = 0.25, p < 0.001). The difference between the control and intervention groups was small at admission, peaked at 18 months, and decreased from 18 to 24 months following discharge.
CONCLUSIONS: Our interdisciplinary intervention improved the long-term postoperative cognitive functioning of older persons with hip fracture in Taiwan.
Abstract: BACKGROUND: People with cognitive impairment and dementia have a poor outcome after a hip fracture surgery, about 30–50% of all those who sustain a hip fracture have dementia. Therefore the aim was to investigate whether a multidisciplinary postoperative intervention program could reduce postoperative complications and improve functional recovery among people with dementia. METHODS: A randomized controlled trial with subgroup analyses among patients with dementia. Sixty-four patients with femoral neck fracture, aged ≥70 years at Umeå University Hospital, Sweden. The intervention consisted of staff education, individualized care planning and rehabilitation, active prevention, detection and treatment of postoperative complications, especially delirium. The staff worked in teams to apply comprehensive geriatric assessment, management and rehabilitation, including a follow-up at 4 months postoperatively. The control group followed conventional postoperative routines. RESULTS: There were fewer postoperative complications in the intervention group such as urinary tract infections, p =0.001; nutritional problems, p =0.025; postoperative delirium, p =0.002; falls, p =0.006. At 4 months a larger proportion in the intervention group had regained their previous independent indoor walking ability performance, p =0.005. At 12 months a larger proportion in the intervention group had regained the activities of daily living (ADL) performance level they had before the fracture, p =0.027. CONCLUSION: This study demonstrates that patients with dementia who suffer a hip fracture can benefit from multidisciplinary geriatric assessment and rehabilitation and should not be excluded from rehabilitation programs.
OBJECTIVE: To determine the effectiveness of interdisciplinary rehabilitation for women with hip fracture who were residents of nursing homes.
DESIGN: Randomised controlled trial.
SUBJECTS: Eleven cognitively impaired women with hip fracture who were previously ambulant.
METHODS: Participants were randomly allocated to usual care (discharge back to the nursing home soon after surgery to the hip fracture) or an inpatient interdisciplinary rehabilitation program.
RESULTS: Participants were severely cognitively impaired and the majority used a walking aid prior to fracturing their hip. There was one early death, and at final follow up (4 months after hip fracture) median (range) Barthel Index was 28 (0-82) for control group and 68 (0-88) for the intervention group.
CONCLUSION: No definite conclusion can be drawn about the effectiveness of the intervention because of its premature termination. However, the study established that it is feasible to provide an interdisciplinary rehabilitation for older people with hip fracture and severe disablement.
BACKGROUND AND AIMS: Delirium is a common postoperative complication in elderly patients which has a serious impact on outcome in terms of morbidity and costs. We examined whether a postoperative multi-factorial intervention program can reduce delirium and improve outcome in patients with femoral neck fractures. METHODS: One hundred and ninety-nine patients, aged 70 years and over (mean age+/-SD, 82+/-6, 74% women), were randomly assigned to postoperative care in a specialized geriatric ward or a conventional orthopedic ward. The intervention consisted of staff education focusing on the assessment, prevention and treatment of delirium and associated complications. The staff worked as a team, applying comprehensive geriatric assessment, management and rehabilitation. Patients were assessed using the Mini Mental State Examination and the Organic Brain Syndrome Scale, and delirium was diagnosed according to DSM-IV criteria. RESULTS: The number of days of postoperative delirium among intervention patients was fewer (5.0+/-7.1 days vs 10.2+/-13.3 days, p=0.009) compared with controls. A lower proportion of intervention patients were delirious postoperatively than controls (56/102, 54.9% vs 73/97, 75.3%, p=0.003). Eighteen percent in the intervention ward and 52% of controls were delirious after the seventh postoperative day (p<0.001). Intervention patients suffered from fewer complications, such as decubitus ulcers, urinary tract infections, nutritional complications, sleeping problems and falls, than controls. Total postoperative hospitalization was shorter in the intervention ward (28.0+/-17.9 days vs 38.0+/-40.6 days, p=0.028). CONCLUSIONS: Patients with postoperative delirium can be successfully treated, resulting in fewer days of delirium, fewer other complications, and shorter length of hospitalization.
OBJECTIVES: Delirium (or acute confusional state) affects 35% to 65% of patients after hip-fracture repair, and has been independently associated with poor functional recovery. We performed a randomized trial in an orthopedic surgery service at an academic hospital to determine whether proactive geriatrics consultation can reduce delirium after hip fracture. DESIGN: Prospective, randomized, blinded. SETTING: Inpatient academic tertiary medical center. PARTICIPANTS: 126 consenting patients 65 and older (mean age 79 +/- 8 years, 79% women) admitted emergently for surgical repair of hip fracture. MEASUREMENTS: Detailed assessment through interviews with patients and designated proxies and review of medical records was performed at enrollment to ascertain prefracture status. Subjects were then randomized to proactive geriatrics consultation, which began preoperatively or within 24 hours of surgery, or 'usual care.' A geriatrician made daily visits for the duration of the hospitalization and made targeted recommendations based on a structured protocol. To ascertain study outcomes, all subjects underwent daily, blinded interviews for the duration of their hospitalization, including the Mini-Mental State Examination (MMSE), the Delirium Symptom Interview (DSI), and the Memorial Delirium Assessment Scale (MDAS). Delirium was diagnosed using the Confusion Assessment Method (CAM) algorithm. RESULTS: The 62 patients randomized to geriatrics consultation were not significantly different (P>.1) from the 64 usual-care patients in terms of age, gender, prefracture dementia, comorbidity, type of hip fracture, or type of surgical repair. Sixty-one percent of geriatrics consultation patients were seen preoperatively and all were seen within 24 hours postoperatively. A mean of 10 recommendations were made throughout the duration of the hospitalization, with 77% adherence by the orthopedics team. Delirium occurred in 20 /62 (32%) intervention patients, versus 32 / 64 (50%) usual-care patients (P =.04), representing a relative risk of 0.64 (95% confidence interval (CI) = 0.37-0.98) for the consultation group. One case of delirium was prevented for every 5.6 patients in the geriatrics consultation group. There was an even greater reduction in cases of severe delirium, occurring in 7/ 60 (12%) of intervention patients and 18 / 62 (29%) of usual-care patients, with a relative risk of 0.40 (95% CI = 0.18-0.89). Despite this reduction in delirium, length of stay did not significantly differ between intervention and usual-care groups (median +/- interquartile range = 5 +/- 2 days in both groups), likely because protocols and pathways predetermined length of stay. In subgroup analyses, geriatrics consultation was most effective in reducing delirium in patients without prefracture dementia or activities of daily living (ADL) functional impairment. CONCLUSIONS: Proactive geriatrics consultation was successfully implemented with good adherence after hip-fracture repair. Geriatrics consultation reduced delirium by over one-third, and reduced severe delirium by over one-half. Our trial provides strong preliminary evidence that proactive geriatrics consultation may play an important role in the acute hospital management of hip-fracture patients.
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.
