A multifactorial intervention program reduces the duration of delirium, length of hospitalization, and mortality in delirious patients

Objectives: To investigate whether an education program and a reorganization of nursing and medical care improved the outcome for older delirious patients.

Postoperative delirium in old patients with femoral neck fracture: a randomized intervention study

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.

Dementia after Delirium in Patients with Femoral Neck Fractures

Objectives: To investigate whether delirium in older patients with femoral neck fractures is associated with an increased risk of developing dementia and a higher mortality rate.

Delirium before and after operation for femoral neck fracture

The aim of this study was to investigate the differences between preoperative and postoperative delirium regarding predisposing, precipitating factors and outcome in older patients admitted to hospital with femoral neck fractures.

Clinical Profile of Delirium in Patients Treated for Femoral Neck Fractures

The incidence of delirium, its predisposing factors, clinical profile, associated symptoms and consequences were investigated in 54 consecutive patients, 19 men and 35 women, mean age 77.1 years, admitted to an ‘ortho-geriatric unit’ with femoral neck fractures. The incidence of postoperative delirium was 15/54 (27.8%) and a logistic regression model found that dementia and a prolonged waiting time for the operation increased the risk of postoperative delirium. Delirium during the night was most common but in 5 patients the delirium was worst in the morning. Patients with delirium suffered more anxiety, depressed mood, emotionalism, delusions and hallucinations. A larger proportion of patients with delirium could not return to their previous dwelling, and a larger proportion of delirious patients were either dead, wheelchair-bound or bedridden at the 6-month follow-up (p < 0.005). The conclusion is that delirium is common and has a serious impact on the outcome after hip fracture surgery.

IMPROVED PERFORMANCE IN ACTIVITIES OF DAILY LIVING AND MOBILITY AFTER A MULTIDISCIPLINARY POSTOPERATIVE REHABILITATION IN OLDER PEOPLE WITH FEMORAL NECK FRACTURE: A RANDOMIZED CONTROLLED TRIAL WITH 1-YEAR FOLLOW-UP

OBJECTIVE To investigate the short- and long-term effects of a multidisciplinary postoperative rehabilitation programme in patients with femoral neck fracture. DESIGN AND SUBJECTS A randomized controlled trial in patients (n = 199) with femoral neck fracture, aged >or= 70 years. METHODS The primary outcomes were: living conditions, walking ability and activities of daily living performance on discharge, 4 and 12 months postoperatively. The intervention consisted of staff education, individualized care planning and rehabilitation, active prevention, detection and treatment of postoperative complications. The staff worked in teams to apply comprehensive geriatric assessment, management and rehabilitation. A geriatric team assessed those in the intervention group 4 months postoperatively, in order to detect and treat any complications. The control group followed conventional postoperative routines. RESULTS Despite shorter hospitalization, significantly more people from the intervention group had regained independence in personal activities of daily living performance at the 4- and 12-month follow-ups; odds ratios (95% confidence interval (CI) ) 2.51 (1.00-6.30) and 3.49 (1.31-9.23), respectively. More patients in the intervention group had also regained the ability to walk independently indoors without walking aids by the end of the study period, odds ratio (95% confidence interval) 3.01 (1.18-7.61). CONCLUSION A multidisciplinary postoperative intervention programme enhances activities of daily living performance and mobility after hip fracture, from both a short-term and long-term perspective.

A multidisciplinary intervention program improved the outcome after hip fracture for people with dementia—Subgroup analyses of a randomized controlled trial

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.

Delirium in older patients admitted to general internal medicine.

Delirium on the day of admission to general internal medicine wards was studied in 400 consecutive patients aged 70 years and above regarding occurrence, associated factors, clinical profile, length of hospital stay, and mortality. The patients were assessed using the Organic Brain Syndrome Scale and the Mini-Mental State Examination, and delirium was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders (4th ed) criteria. Delirium on the day of admission occurred in 31.3% of the patients and was independently associated with old age, fever on the day of admission (≥ 38°C), treatment with neuroleptics, impaired vision, male sex, and previous stroke. Delirious patients had longer hospital stay (15.4 vs 9.5 days, P < .001), a higher mortality rate during hospitalization (11/125 vs 5/275, P < .001), and a higher 1-year mortality rate (45/125 vs 55/275, P = .001). Delirium is a common complication with often easily identified causes, and it has a serious impact on outcome for older medical patients.

Symptom Profile of Delirium in Older People With and Without Dementia

Clinical profiles of delirium in 717 older people with and without dementia age 75 years and older in 4 different types of care were studied. Delirium and dementia were diagnosed according to DSM-IV criteria. Delirious demented participants (n = 135) had more often had previous delirium episodes and were more often being treated with analgesics compared to delirious participants without dementia (n = 180). The clinical profile of delirium in the participants with dementia was more frequently characterized by aggressivity, latency in reaction to verbal stimuli, restlessness and agitation, delusions, anxiousness, hallucinations, and a poorer orientation and recognition. Delirium among demented participants more often had a fluctuating course during the day and was more common in the evening and at night. In conclusion, clinical profiles of delirium in participants with and without dementia are different, which might indicate a different etiology or pathophysiology, or both, and a need for different treatment strategies.

Symptom Profile of Postoperative Delirium in Patients With and Without Dementia

This study compares the symptom profile of patients with postoperative delirium after femoral neck fracture surgery in those with and without dementia. In this study, 129 patients of age ≥70 years (mean age ±SD, 86±6 yr, 72% women) with postoperative delirium, were included. Delirium and dementia were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) criteria. Of the 129 patients with delirium, 54 (42%) had a dementia disorder. Patients with delirium superimposed on dementia more often had any hyperactive and pure emotional delirium. Communication difficulties and symptoms such as restlessness/agitation, aggressive behavior, and irritability were more commonly found in the dementia group. In contrast, patients with delirium but without dementia were more often diagnosed with pure hypoactive and any psychotic delirium. The symptom profile of postoperative delirium varies according to whether it occurs in patients with or without dementia. This may indicate that postoperative delirium among patients with hip fracture differs based on the presence or absence of dementia.
