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.

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.

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.

Daily life among the oldest old with and without previous hip fractures

The aim of this cross-sectional study was to describe the oldest old, with and without previous hip fracture with regard to their ability to perform personal and instrumental activities of daily living (ADL); home adaptations received; possession of assistive devices; perceived health and morale. A random sample drawn from the population of 85-year-olds, all 90-year-olds and all ≥95-year-olds (n=253) in Umeå, a city in northern Sweden, were examined. Data obtained from assessments and interviews carried out in the participants’ homes, as well as data from medical charts, were analysed. Those with an earlier hip fracture (n=58) had more difficulties in performing both personal and instrumental ADLs than those without (n=195) but regarding individual home adaptations and the possession of assistive devices for personal care, no differences were detected between the groups. Self-perceived health and morale were equally good in both groups. The conclusion drawn is that lifelong consequences, in the form of reduced abilities to perform ADLs and wheelchair dependency are common among the oldest old after a hip fracture. Therefore, trials concerning the effects of more extensive and prolonged rehabilitation following hip fracture would be of great interest

“The balancing act”— Licensed practical nurse experiences of falls and fall prevention: a qualitative study

BackgroundFalls are common in old age and may have serious consequences. There are many strategies to predict and prevent falls from occurring in long-term care and hospitals. The aim of this study was to describe licensed practical nurse experiences of predicting and preventing further falls when working with patients who had experienced a fall-related fracture. Licensed practical nurses are the main caretakers that work most closely with the patients.MethodsA qualitative study of focus groups interviews and field observations was done. 15 licensed practical nurses from a rehabilitation ward and an acute ward in a hospital in northern Sweden were interviewed. Content was analyzed using qualitative content analysis.ResultsThe result of the licensed practical nurse thoughts and experiences about risk of falling and fall prevention work is represented in one theme, “the balancing act”. The theme includes three categories: “the right to decide”, “the constant watch”, and “the ongoing negotiation” as well as nine subcategories. The analysis showed similarities and differences between rehabilitation and acute wards. At both wards it was a core strategy in the licensed practical nurse work to always be ready and to pay attention to patients’ appearance and behavior. At the rehabilitation ward, it was an explicit working task to judge the patients’ risk of falling and to be active to prevent falls. At the acute ward, the words “risk of falling” were not used and fall prevention were not discussed; instead the licensed practical nurses used for example “dizzy and pale”. The results also indicated differences in components that facilitate workplace learning and knowledge transfer.ConclusionsDifferences between the wards are most probably rooted in organizational differences. When it is expected by the leadership, licensed practical nurses can express patient risk of falling, share their observations with others, and take actions to prevent falls. The climate and the structure of the ward are essential if licensed practical nurses are to be encouraged to routinely consider risk of falling and implement risk reduction strategies.

The development of a virtual reality system to study tendency of falling among older people

Injuries related to falls are a major threat to older persons health. A fall may not only result in an injury, but also in a decreased sense of autonomy in the persons daily life. In order to be able to prevent such falls there is a need to further understand the complex mechanisms involved in balance and walking. Here we present an immersive virtual reality system in which a person can move around, while being subjected to various events, which may influence balance and walking.

Development of dementia in patients with femoral neck fracture who experience postoperative delirium : A three-year follow-up study

It remains unclear to what extent postoperative delirium (POD) affects the incidence of dementia in hip fracture patients, and the methods used to detect delirium and dementia require validation. The aim of this study was to investigate the development of dementia within 3 years of femoral neck fracture repair surgery, with a focus on POD as a potential predictive factor.

Effects of geriatric interdisciplinary home rehabilitation on complications and readmissions after hip fracture: a randomized controlled trial:

Objective: This pre-planned secondary analysis of geriatric interdisciplinary home rehabilitation, which was initially found to shorten the postoperative length of stay in hospital for older individuals following hip fracture, investigated whether such rehabilitation reduced the numbers of complications, readmissions, and total days spent in hospital after discharge during a 12-month follow-up period compared with conventional geriatric care and rehabilitation. Design: Randomized controlled trial. Setting: Geriatric department, participants’ residential care facilities, and ordinary housing. Subjects: Individuals aged ⩾70 years with acute hip fracture (n = 205) were included. Intervention: Geriatric interdisciplinary home rehabilitation was individually designed and aimed at early discharge with the intention to prevent, detect, and treat complications after discharge. Main measures: Complications, readmissions, and days spent in hospital were registered from patients’ digital records and interviews conducted during hospitalization and at 3- and 12-month follow-up visits. Results: No significant difference in outcomes was observed. Between discharge and the 12-month follow-up, among participants in the geriatric interdisciplinary home rehabilitation group (n = 106) and control group (n = 93), 57 (53.8%) and 44 (47.3%) had complications (P = 0.443), 46 (43.4%) and 38 (40.9%) fell (P = 0.828), and 38 (35.8%) and 27 (29.0%) were readmitted to hospital (P = 0.383); the median total days spent in hospital were 11.5 and 11.0 (P = 0.353), respectively. Conclusion: Geriatric interdisciplinary home rehabilitation for older individuals following hip fracture resulted in similar proportions of complications, readmissions, and total days spent in hospital after discharge compared with conventional geriatric care and rehabilitation.
