The influence of dementia on injury-related hospitalisations and outcomes in older adults

The Ability of Physical Performance Measures to Identify Fall Risk in Older Adults Living With Dementia: A Systematic Review and Meta-Analysis

OBJECTIVES

To determine whether physical performance measures commonly used in clinical settings can discriminate fallers from nonfallers and predict falls in older adults with dementia.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Older adults with dementia residing in the community, hospitals, and residential care facilities.

METHODS

MEDLINE, Embase, PsycINFO, CINAHL, SPORTDiscus, the Cochrane Library, and the PEDro databases were searched from inception until December 27, 2023 (PROSPERO registration number: CRD42022303670). Retrospective or prospective studies that evaluated the associations between physical performance measures and falls in older adults with dementia were included. A random effects model was used to calculate the standardized mean difference (SMD) and 95% CI for each physical performance measure between fallers and nonfallers. Sensitivity analyses were conducted on the longitudinal studies to determine the ability of physical performance measures to predict future falls.

RESULTS

Twenty-eight studies were included in this review (n = 3542). The 5-time chair stand test [SMD = 0.23 (0.01, 0.45)], the Berg Balance Scale [SMD = -0.52 (-0.87, -0.17)], postural sway when standing on the floor [SMD = 0.25 (0.07, 0.43)] and on a foam surface [SMD = 0.45 (0.25, 0.66)], and the Short Physical Performance Battery total score [SMD = -0.46 (-0.66, -0.27)] could discriminate fallers from nonfallers. Sensitivity analyses showed that gait speed could predict future falls in longitudinal cohort studies [SMD = -0.29 (-0.49, -0.08)]. Subgroup analyses showed that gait speed [SMD = -0.21 (-0.38, -0.05)] and the Timed Up and Go test [SMD = 0.54 (0.16, 0.92)] could identify fallers staying in residential care facilities or hospitals.

CONCLUSIONS AND IMPLICATIONS

The 5-time chair stand test, the Berg Balance Scale, postural sway when standing on the floor and a foam surface, and the Short Physical Performance Battery can be used to predict falls in older adults with dementia. Gait speed and the Timed Up and Go test can be used to predict falls in institutionalized older adults with dementia. Clinicians are recommended to use these physical performance measures to assess fall risk in older adults with dementia.

The Health Outcomes of a Telegeriatrics Follow-Up Model on Dementia Patients and Their Caregivers in Cairo

Background/Purpose: Older patients living with dementia and their caregivers are ideal beneficiaries of telemedicine, cost-effectiveness, caregiver satisfaction, and physician acceptance. The aim is to study the effect of a telemedicine dementia enabled program on the health outcome of dementia patients and their caregivers, as regard the patient outcome, caregiver stress, and caregiver satisfaction. Methods: Ninety-seven (n = 97) elderly subjects were recruited from the outpatient clinics and inpatient ward of Geriatrics Hospital, Ain Shams University Hospitals. Seventy subjects completed 6 months of follow-up using a telegeriatrics model. Patient outcomes (delirium, behavioral and psychological symptoms of dementia [BPSD], and need for home consultations, emergency room [ER] visits, clinic visits, and hospital admissions) were assessed and followed. Caregiver stress was evaluated and monitored using the abridged Arabic version of the Zarit Burden Interview ZBI-A. Caregiver satisfaction was assessed using dedicated satisfaction questionnaire designed by Ain Shams Virtual Hospital. Results: elirium episodes, BPSD episodes, and the need for home consultations, clinic visits, ER visits, and hospital admissions. This was statistically significant after the second, fourth, and sixth months of follow-up (p-value <0.001). In addition, the telegeriatrics follow-up model had a positive effect on both caregiver stress and caregiver satisfaction. Conclusions: The telegeriatrics follow-up model is a useful tool in the improvement of health outcomes of dementia patients, reduction of caregiver stress, and achievement of caregiver satisfaction.

Short-Term Medication Effect on Fall Risk in Multimorbid Inpatients with Dementia

INTRODUCTION

Dementia increases the risk of falls and fall-related injuries, which may be caused by inappropriate medication use. To date, there is little evidence on which medications are more likely to cause falls. We therefore investigated the effects of medication use and medication changes 48 h before falls in hospitalised patients with dementia.

METHODS

This matched case-control study included 74 patients with a mean age of 83 years (38% women) who had been hospitalised for at least 7 days. Information on medications, diagnoses, disease severity, use of walking aids, falls, and demographics was collected from electronic medical records. The effects of the number of medications and psychotropics, equivalent daily doses of antidepressants, antipsychotics and benzodiazepines, anticholinergic burden, medication initiation, dose change, medication discontinuation, as-needed medications, opioid use and the presence of fall-increasing diseases were examined separately for the periods 0 h-24 h and 24 h-48 h before the falls using binomial logistic regression analyses.

RESULTS

Falls increased significantly with higher daily antipsychotic doses 24 h before the fall. In addition, the rate of falls increased with higher anticholinergic burden and prevalence of medication discontinuation 24-48 h before the fall. Notably, the total number of medications and psychotropic medications had no effect on the incidence of falls.

CONCLUSION

With regard to the short-term effects of medication on fall risk, particular attention should be paid to the daily dose of antipsychotics, anticholinergic burden and medication discontinuation. Further studies with larger samples are needed to confirm the results of this study.

Cross-Lagged Panel Analysis between Physical Frailty, Cognitive Function, and Falls by Sex

OBJECTIVES

This study investigated the reciprocal longitudinal relationships between physical frailty (PF), cognitive function (CF), and falls among community-dwelling older adults, according to sex. The study proposed hypotheses that present PF and CF will affect the occurrence of falls 2 years later.

DESIGN

Secondary data analysis using the first (T1, 2016-2017) and second (T2, 2018-2019) waves of the Korean Frailty and Aging Cohort Study (KFACS).

SETTING AND PARTICIPANTS

A total of 2318 community-dwelling older adults aged 70-84 years in South Korea; mean (SD) age: 75.72 (3.83) years; 47.7% men.

METHODS

PF and CF were measured with the modified version of the Fried Frailty Phenotype and the Korean version of the Mini-Mental State Examination, respectively. The number of falls were assessed. Multigroup cross-lagged panel analysis was used.

RESULTS

The results showed that relationships between PF, CF, and falls were maintained over time through an autoregressive effect. PF at T1 had a statistically significant longitudinal relationship with fall experience at T2 [standardized regression coefficient (β) = 0.087, 95% CI 0.045-0.129; P < .001], and fall experience at T1 had a significant longitudinal relationship with PF at T2 (β = 0.041, 95% CI 0.006-0.076; P = .020). There was no statistically significant relationship between CF and fall experience. PF and CF had statistically significant reciprocal longitudinal relationships (all P < .001). Based on sex, there was a statistically significant longitudinal relationship between fall experience at T1 and PF at T2 for men only (β = 0.063, 95% CI 0.012-0.114; P = .015).

CONCLUSIONS AND IMPLICATIONS

Findings highlight that health care providers should plan fall prevention programs through early intervention for PF improvement along with improvement and maintenance of CF. Specifically, even if older men are currently healthy and have a low risk of falls, it is important to prevent future fatal PF through prior interventions, such as risk activities attention and concerns about falls.

Alzheimer's disease and its associated risk of bone fractures: a narrative review

Background

Alzheimer's disease (AD) is a neurodegenerative disorder that is the major cause of dementia in the aged population. Recent researches indicate that patients with AD have a significantly increased fracture risk, but the pathological mechanisms are still unclear.

Objective

We systematically reviewed studies regarding bone fracture risk in AD to uncover links between the pathologies of osteoporosis and AD.

Methods

We searched the literature using the databases of PubMed, Web of Science, Embase and Cochrane Library. Studies were included if they evaluated bone fracture risk in AD patients and if they explored the pathogenesis and prevention of bone fractures in these patients.

Results

AD patients had a significantly higher risk of bone fractures than age-matched controls. Multiple factors contributed to the increased risk of bone fractures in AD patients, including the direct effects of amyloid pathology on bone cells, abnormal brain-bone interconnection, Wnt/β-catenin signalling deficits, reduced activity, high risk of falls and frailty, and chronic immune activity. Exercise, prevention of falls and fortified nutrition were beneficial for reducing the fracture risk in AD patients. However, the efficacy of anti-osteoporotic agents in preventing bone fractures should be further evaluated in AD patients as corresponding clinical studies are very scarce.

Conclusion

Alzheimer's disease patients have increased bone fracture risk and decreased bone mineral density owing to multiple factors. Assessment of anti-osteoporotic agents' efficacy in preventing bone fractures of AD patients is urgently needed.

IMOVE: Protocol for a randomized, controlled 2x2 factorial trial of improvisational movement and social engagement interventions in older adults with early Alzheimer's disease

Background

In addition to cognitive impairment, people with Alzheimer's disease (PWAD) experience neuropsychiatric symptoms (e.g., apathy, depression), altered gait, and poor balance that further diminish their quality of life (QoL). Here, we describe a unique, randomized, controlled trial to test the hypothesis that both movement and social engagement aspects of a group dance intervention alter the connectivity of key brain networks involved in motor and social-emotional functioning and lead to improved QoL in PWAD.

Methods

IMOVE (NCT03333837) was a single-center, randomized, controlled 2x2 factorial trial that assigned PWAD/caregiver dyads to one of 4 study conditions (Movement Group, Movement Alone, Social Group, or Usual Care control). The Movement Group participated in twice-weekly group improvisational dance (IMPROVment® Method) classes for 12 weeks. The Movement Alone intervention captured the same dance movement and auditory stimuli as the group class without social interaction, and the Social Group used improvisational party games to recapitulate the fun and playfulness of the Movement Group without the movement. The primary outcome was change in QoL among PWAD. Key secondary outcomes were functional brain network measures assessed using graph-theory analysis of resting-state functional magnetic resonance imaging scans, as well as neuropsychiatric symptoms, gait, and balance.

Results

A total of 111 dyads were randomized; 89 completed the study, despite interruption and modification of the protocol due to COVID-19 restrictions (see companion paper by Fanning et al.). The data are being analyzed and will be submitted for publication in 2023.

Injury-related emergency department use among assisted living residents with Alzheimer's disease and related dementias

BACKGROUND

Injuries are a leading cause of emergency department (ED) visits among older adults, and individuals with Alzheimer's disease and related dementias (ADRD) may be at particular risk. We compared injury-related ED use among assisted living (AL) residents with and without ADRD and assessed differences in the risk of injury-related ED visits among individuals with ADRD residing in ALs with memory care designation versus general AL.

METHODS

Using Medicare claims, we identified a cohort of fee-for-service beneficiaries who lived in AL in 2018 and resided in one of 20 states with site-specific information on memory care designation (n = 116,754). Outcomes included all injury-related ED visits and injury-related ED visits resulting in hospitalization in the calendar year 2018. We fit multilevel models of the association between ADRD and outcomes, adjusting for resident demographic characteristics and chronic conditions, license type characteristics, and AL characteristics, with random intercepts at the AL and license type levels. Among residents with ADRD, we examined whether memory care licensure was associated with injury-related ED visits.

RESULTS

The adjusted risk of injury-related ED use during the year was 20.1% (95% CI: 19.6%, 20.6%) for residents with ADRD compared to 16.1% for residents without ADRD (95% CI: 15.7%, 16.5%; p < 0.001). The adjusted risk of injury-related ED use ending in hospitalization was 4.9% (95% CI: 4.6%, 5.1%) for AL residents with ADRD and 3.9% for residents without ADRD (95% CI: 3.8%, 4.1%; p < 0.001). There were no significant differences in injury-related ED visits between residents with ADRD in ALs with memory care designation and residents in general AL.

CONCLUSIONS

Injury-related ED visits are common among AL residents with ADRD and residents in memory care, but residents in memory care AL experienced similar risks of injury as those in general AL. Further research should identify modifiable factors that can prevent injury among AL residents with ADRD.

The Effect of Exercise on Falls in People Living with Dementia: A Systematic Review

BACKGROUND

People living with dementia (PWD) are at a heightened risk for falls. However, the effects of exercise on falls in PWD are unclear.

OBJECTIVE

To conduct a systematic review of randomized controlled trials (RCTs) examining the efficacy of exercise to reduce falls, recurrent falls, and injurious falls relative to usual care among PWD.

METHODS

We included peer-reviewed RCTs evaluating any exercise mode on falls and related injuries among medically diagnosed PWD aged ≥55years (international prospective register of systematic reviews (PROSPERO) ID:CRD42021254637). We excluded studies that did not solely involve PWD and were not the primary publication examining falls. We searched the Cochrane Dementia and Cognitive Improvement Group's Specialized Register and grey literature on 08/19/2020 and 04/11/2022; topical categories included dementia, exercise, RCTs, and falls. We evaluated the risk of bias (ROB) using the Cochrane ROB Tool-2 and study quality using the Consolidated Standards of Reporting Trials.

RESULTS

Twelve studies were included (n = 1,827; age = 81.3±7.0 years; female = 59.3%; Mini-Mental State Examination = 20.1±4.3 points; intervention duration = 27.8±18.5 weeks; adherence = 75.5±16.2%; attrition = 21.0±12.4%). Exercise reduced falls in two studies [Incidence Rate Ratio (IRR) range = 0.16 to 0.66; fall rate range: intervention = 1.35-3.76 falls/year, control = 3.07-12.21 falls/year]; all other studies (n = 10) reported null findings. Exercise did not reduce recurrent falls (n = 0/2) or injurious falls (n = 0/5). The RoB assessment ranged from some concerns (n = 9) to high RoB (n = 3); no studies were powered for falls. The quality of reporting was good (78.8±11.4%).

CONCLUSION

There was insufficient evidence to suggest that exercise reduces falls, recurrent falls, or injurious falls among PWD. Well-designed studies powered for falls are needed.

Clinical Quality Indicators for Monitoring Hospitalizations Among Older People with Dementia Accessing Aged Care Services

BACKGROUND

There is a need for clinical quality indicators (CQIs) that can be applied to dementia quality registries to monitor care outcomes for people with Alzheimer's disease and other forms of dementia.

OBJECTIVE

To develop tertiary and primary care-based dementia CQIs for application to clinical registries for individuals with dementia accessing aged care services and determine 1) annual trends in CQI incidence between 2011-2012 and 2015-2016, 2) associated factors, and 3) geographic and facility variation in CQI incidence.

METHODS

This retrospective repeated cross-sectional study included non-Indigenous individuals aged 65-105 years who lived with dementia between July 2008-June 2016, were assessed for government-funded aged care services, and resided in New South Wales or Victoria (n = 180,675). Poisson or negative binomial regression models estimated trends in annual CQI incidence and associated factors. Funnel plots examined CQI variation.

RESULTS

Between 2011-2012 and 2015-2016, CQI incidence increased for falls (11.0% to 13.9%, adjusted incidence rate ratio (aIRR) 1.05 (95% CI 1.01-1.06)) and delirium (4.7% to 6.7%, aIRR 1.09 (95% CI 1.07-1.10)), decreased for unplanned hospitalizations (28.7% to 27.9%, aIRR 0.99 (95% CI 0.98-0.99)) and remained steady for fracture (6.2% to 6.5%, aIRR 1.01 (95% CI 0.99-1.01)) and pressure injuries (0.5% to 0.4%, aIRR 0.99 (95% CI 0.96-1.02)). Being male, older, having more comorbidities and living in a major city were associated with higher CQI incidence. Considerable geographical and facility variation was observed for unplanned hospitalizations and delirium CQIs.

CONCLUSIONS

The CQI results highlighted considerable morbidity. The CQIs tested should be considered for application in clinical quality registries to monitor dementia care quality.

The value of compassion: Healthcare savings of palliative care consults in trauma

BACKGROUND

The effects of palliative care (PC) consultation on patient costs and hospitalization metrics in the adult trauma population are unclear.

STUDY DESIGN

We interrogated our Level I trauma center databases from 1/1/19 to 3/31/21 for patients age ≥18 admitted to the trauma service. Patients undergoing PC consult were matched using propensity scoring to those without PC consultation based on age, admission Glasgow Coma Scale score, Injury Severity Score and Head Abbreviated Injury Scale. Total costs, total cost per day, hospital length of stay (LOS), ICU LOS, intubation days, discharge disposition, and rates of nephrology consultation and tracheostomy/feeding tube placements were compared.

RESULTS

140 unique patients underwent PC consultation and were matched to a group not receiving PC consult during the same period. Median total costs in the PC cohort were $39,532 compared to $70,330 in the controls (p<0.01).  Median costs per day in the PC cohort were $3,495 vs $17,970 in the controls (p<0.01).  Median costs per ICU day in the PC cohort were $3,774 vs $17,127 in the controls (p<0.01).  Mean hospital LOS (15.7 vs 7 days), ICU LOS (7.9 vs 2.9 days), and ventilator days (5.1 vs 1.5) were significantly higher in the PC cohort (all p<0.01).  Rates of nephrology consultation (8.6 vs 2.1%, p = 0.03) and tracheostomy/feeding tube placements (12.1 vs 1.4%, p<0.01) were also higher in the PC group.  Patients were more likely to discharge to hospice if they received a PC consult (33.6 vs 2.1%, p<0.01).  Mean time to PC consult was 7.2 days (range 1 hour to 45 days). LOS post-consult correlated positively with time to PC consultation (r = 0.27, p<0.01).

CONCLUSION

Expert PC services are known to alleviate suffering and avert patient goal- and value-incongruent care. While trauma patients demand significant resources, PC consultation offered in concordance with life-sustaining interventions is associated with significant savings to patients and the healthcare system. Given the correlation between LOS following PC consult and time to PC consult, savings may be amplified by earlier PC consultation in appropriate patients.

Risk factors for in-hospital death in elderly patients over 65 years of age with dementia: A retrospective cross-sectional study

As the population continues to age, dementia is becoming a huge social, economic, and healthcare burden. However, the risk factors for in-hospital death in elderly patients over 65 years of age with dementia are not well understood. Identifying factors that affect their prognosis could help clinicians with scientific decision-making. To examine the risk factors for in-hospital death in elderly patients over 65 years of age with dementia in the Geriatric Department of West China Hospital. In this retrospective, cross-sectional study, we analyzed inpatients aged ≥65 years with dementia between 2010 and 2016 using electronic medical records from the Information Center of West China Hospital. The risk factors for death were assessed using multivariable logistic regression. Out of a total of 2986 inpatients with dementia, 3.4% died. Patient deaths were related to digestive diseases, respiratory diseases, circulatory diseases, urinary diseases, and chronic obstructive pulmonary disease, whereas patient survival was associated with osteoporosis and Parkinson disease. Patients with a mean length of hospital stay of ≥60 days had an increased risk of death (all P <.05). In the multiple logistic regression analysis, age ≥80 years, digestive diseases, respiratory diseases, urinary diseases, diabetes, chronic obstructive pulmonary disease, and ≥7 comorbidities were risk factors for death. Mortality in hospitalized older patients with dementia is low, but some risk factors may be easily ignored. These findings could raise awareness among clinicians and caregivers about risk factors in hospitalized older patients, particularly hospitalized elderly patients with multiple comorbidities. Therefore, to reduce mortality, early prevention and management of potential risks are necessary.

A framework for rehabilitation for older adults living with dementia

Introduction & Background

The aging of the population assures increased prevalence of Individuals Living with Dementia (ILwD) and there will be an increased representation of this cohort requiring physical rehabilitation. If physical therapists (PTs) manage these patients as they do their age-matched, cognitively-intact peers, they will likely be unsuccessful. ILwD have unique needs related to interpersonal and pragmatic components of rehabilitation. Therapeutic nihilism (doubting the benefit of therapy) is well-documented in PTs, either because of existing biases about dementia or previous challenges in working with ILwD. Physical rehabilitation eligibility and placement decisions are often made by PTs without special training in dementia, based upon brief exposure to patients in environments not well-designed for their best functioning. This can lead to underestimation of rehabilitation potential and denial of future PT services. PTs who work with ILwD desire more practical knowledge and targeted skills. Those with more education and training have a more positive attitude and outlook related to ILwD.

Purpose

The purpose of this paper is to introduce a framework for rehabilitation with ILwD equipped with pragmatic ideas to facilitate therapeutic success. The four primary components of the model are: (1) Establish a personal RELATIONSHIP, (2) Use intentional verbal and nonverbal COMMUNICATION, (3) Understand and optimize MOTOR LEARNING capabilities, and (4) Create a safe, purposeful ENVIRONMENT. Specific strategies to help PTs optimize each component are provided with supporting evidence. The model is intended to be dynamic, encouraging PTs to capitalize on the most accessible strategies within their control for a given patient and setting.

Implications

This framework provides a practical resource for working with ILwD with immediate implications for facilitating therapeutic success. The model is displayed in a schematic that reminds the reader of ideas at a glance within the context of each of the components. If an appreciation for this content was among core competencies required among PTs working with ILwD, perhaps there would be significantly fewer patients written off as “uncooperative” or “unable to participate” in PT.

Testing the sensitivity of two dementia knowledge instruments in dementia workforce education

BACKGROUND

The importance of dementia education in improving the care and support that people living with dementia is well established. Previous research has shown ceiling effects in pre and post educational intervention measures of dementia knowledge using Knowledge in Dementia Scale (KIDE) on post-registered health and social care staff in Scotland. The aim was to test the sensitivity of two dementia knowledge instruments, namely the (KIDE) and the Dementia Knowledge Assessment Scale (DKAS).

DESIGN

A pre and post evaluation comparison of two dementia knowledge scales.

SETTING

The tenth cohort of Scotland's National Dementia Champions Education Programme, September 2019-March 2020.

PARTICIPANTS

Post-registered Health and Social Care staff (n = 117).

METHODS

Both the DKAS and KIDE scales were administered pre and post programme delivery. Wilcoxon signed-rank tests were performed to examine T1 - T2 differences in dementia knowledge for both validated measures.

RESULTS

Ceiling effects continued to be present for the KIDE scale at T1 and T2. The DKAS responses showed a different score distribution than that achieved by the KIDE. Ceiling effects noted for KIDE at T1 were not present for the DKAS. Further, at T2, only 6% of respondents scored the maximum on the DKAS.

CONCLUSIONS

The DKAS appears to be a more useful instrument for measuring knowledge in post-registered health and social care staff; however, there was some evidence of ceiling effects post-intervention. There is a need for both scales to be tested in more educationally diverse populations, so educators and researchers can make informed decisions about the instrument's target range. Additionally, further research is needed to develop new sets of dementia knowledge items suitable for use in trained health and social care staff.

Risk factors for falls in older people with cognitive impairment living in the community: Systematic review and meta-analysis

PURPOSE

This systematic review aimed to identify risk factors for prospectively ascertained falls, focusing on those that are potentially modifiable (physical and neuropsychological factors), in older people with cognitive impairment living in the community.

RESULTS

A comprehensive search of five databases identified 16 high quality (Newcastle-Ottawa Scale ≥8/9) relevant articles. Meta-analyses were undertaken for five potential fall risk factors. Of these, fallers had significantly poorer balance (standardized mean difference = 0.62, 95 %CI 0.45, 0.79) with low heterogeneity. Global cognition was not significantly associated with faller status in a meta-analysis with low heterogeneity. Meta-analyses of mobility (Timed Up-and-Go), gait speed and depressive symptoms had high heterogeneity and were not statistically significant or were borderline significant (p = 0.05). Sensitivity analyses (removing one study sample's results that differed markedly from the other included samples) reduced heterogeneity to 0% and revealed fallers had significantly poorer mobility and more depressive symptoms than non-fallers. Fallers also walked significantly slower, but heterogeneity remained high.

CONCLUSIONS

In older people with cognitive impairment, fallers presented with balance deficits, poor mobility, slow gait speed and depressive symptoms. Reduced global cognition was not associated with falls. These findings suggest that interventions should target balance impairment and reveal that more high-quality research is needed.

A Scoping Review of Care Trajectories across Multiple Settings for Persons with Dementia

Multiple transitions across care settings can be disruptive for older adults with dementia and their care partners, and can lead to fragmented care with adverse outcomes. This scoping review was conducted to identify and classify care trajectories across multiple settings for people with dementia, and to understand the prevalence of multiple transitions and associated factors at the individual and organizational levels. Searches of three databases, limited to peer-reviewed studies published between 2007 and 2017, provided 33 articles for inclusion. We identified 26 distinct care trajectories. Common trajectories involved hospital readmission or discharge from hospital to long-term care. Factors associated with transitions were identified mainly at the level of demographic and medical characteristics. Findings suggest a need for investing in stronger community-based systems of care that may reduce transitions. Further research is recommended to address knowledge gaps about complex and longitudinal care trajectories and trajectories experienced by sub-populations of people living with dementia.

Exploring The Background, Context And Stressors Of Caregiving To Elderly Burned Patients: A Qualitative Inquiry

Elderly persons are at risk of experiencing burns and require support from both formal and informal caregivers. Informal caregiving in this situation has been minimally explored. Guided by the Stress Process Model, this study aimed at exploring the background, context, and stressors of informal caregivers of elderly burned persons during hospitalisation. A qualitative descriptive design was utilised. Purposive sampling approach was used to recruit fourteen (14) informal caregivers who rendered care to elderly burned persons during hospitalisation. Interviews were conducted and transcribed verbatim following which directed content analysis was undertaken deductively. Three categories and six sub-categories emerged which characterise the background, context, and stressors of informal caregiving to elderly burn patients. All the injuries occurred in the home setting and its sudden nature led to varied post-burn emotional responses which characterised the context of burns caregiving. Primary stressors that emerged were related to the injury, actual caregiving demand, and concerns regarding increasing frailty levels. Secondary stressors identified were financial concerns and lifestyle changes. The findings suggest that the occurrence of burn injury served as a precursor to post-burn stress response among informal caregivers. Increasing frailty levels, adequacy of household safety measures and financial issues were key concerns which emphasise the need for psychosocial/ transitional support, innovative healthcare financing measures and continuing education on burns prevention in the home setting.

Dementia and patient outcomes after hip surgery in older patients: A retrospective observational study using nationwide administrative data in Japan

OBJECTIVE

To investigate whether dementia is associated with incidence of adverse events and longer hospital stays in older adults who underwent hip surgery, after adjusting for individual social and nursing care environment.

DESIGN AND SETTING

Retrospective observational study using the linked data between the Japanese Diagnosis Procedure Combination database and the reports of the medical functions of hospital beds database in Japan (April 2016-March 2017).

PARTICIPANTS

A total of 48,797 individuals aged 65 and older who underwent hip surgery and were discharged during the study period.

METHODS

Outcomes included in-hospital death, in-hospital pneumonia, in-hospital fracture, and longer hospital stay. We performed two-level, multilevel models adjusting for individual and hospital characteristics.

RESULTS

Among all participants, 20,638 individuals (42.3%) had dementia. The incidence of adverse events for those with and without dementia included in-hospital death: 2.11% and 1.11%, in-hospital pneumonia: 0.15% and 0.07%, and in-hospital fracture: 3.76% and 3.05%, respectively. The median (inter quartile range) length of hospital stay for those with and without dementia were 26 (19-39) and 25 (19-37) days, respectively. Overall, the odds ratios (95% confidence interval (CI)) of dementia for in-hospital death, in-hospital pneumonia, and in-hospital fracture were 1.12 (0.95-1.33), 0.95 (0.51-1.80), and 1.08 (0.92-1.25), respectively. Dementia was not associated with the length of hospital stay (% change) (-0.7%, 95% CI -1.6-0.3%). Admission from home, discharge to home, and lower nurse staffing were associated with prolonged hospital stays.

CONCLUSIONS

Although adverse events are more likely to occur in older adults with dementia than in those without dementia after hip surgery, we found no evidence of an association between dementia and adverse events or the length of hospital stay after adjusting for individual social and nursing care environment.

Cognitive Domain Associations with Balance Performance in Community-Dwelling Older People with Cognitive Impairment

BACKGROUND

In older people with cognitive impairment (CI), executive function (EF) has been associated with motor performance including balance and gait. The literature examining and supporting a relationship between balance performance and other cognitive domains is limited.

OBJECTIVE

To investigate the relationship between global cognition and cognitive domain function and balance performance in older people with CI.

METHODS

The iFOCIS randomized controlled trial recruited 309 community-dwelling older people with CI. Baseline assessments completed before randomization were used for analyses including the Addenbrooke's Cognitive Examination-III (ACE-III; global cognition) and its individual cognitive domains (attention; memory; verbal fluency; language; visuospatial ability) and the Frontal Assessment Battery (FAB), a measure of EF. A composite balance score was derived from postural sway and leaning balance tests.

RESULTS

In linear regression analyses adjusted for covariates, global cognition and each cognitive domain were significantly associated with balance performance. EF (verbal fluency; β= -0.254, p < 0.001, adjusted R2 = 0.387) and visuospatial ability (β= -0.258, p < 0.001, adjusted R2 = 0.391) had the strongest associations with balance performance. In a comprehensively adjusted multivariable model including all of the ACE-III cognitive domains, visuospatial ability and EF (verbal fluency) were independently and significantly associated with balance performance.

CONCLUSION

Poorer global cognition and cognitive domain function were associated with poorer balance performance in this sample of people with CI. Visuospatial ability and EF were independently associated with balance, highlighting potential shared neural networks and the role higher-level cognitive processes and spatial perception/processing play in postural control.

The associations between social, built and geophysical environment and age-specific dementia mortality among older adults in a high-density Asian city

Background

Although socio-environmental factors which may affect dementia have widely been studied, the mortality of dementia and socio-environmental relationships among older adults have seldom been discussed.

Method

A retrospective, observational study based on territory-wide register-based data was conducted to evaluate the relationships of four individual-level social measures, two community-level social measures, six short-term (temporally varying) environmental measures, and four long-term (spatially varying) environmental measures with dementia mortality among older adults in a high-density Asian city (Hong Kong), for the following decedents: (1) all deaths: age >= 65, (2) “old-old”: age > = 85, (3) “mid-old”: aged 75–84, and (4) “young-old”: aged 65–74.

Results

This study identified 5438 deaths (3771 old-old; 1439 mid-old; 228 young-old) from dementia out of 228,600 all-cause deaths among older adults in Hong Kong between 2007 and 2014. Generally, regional air pollution, being unmarried or female, older age, and daily O₃ were associated with higher dementia mortality, while more urban compactness and greenness were linked to lower dementia mortality among older adults. Specifically, being unmarried and the age effect were associated with higher dementia mortality among the “old-old”, “mid-old” and “young-old”. Regional air pollution was linked to increased dementia mortality, while urban compactness and greenness were associated with lower dementia mortality among the “old-old” and “mid-old”. Higher daily O₃ had higher dementia mortality, while districts with a greater percentage of residents whose native language is not Cantonese were linked to lower dementia mortality among the “old-old”. Economic inactivity was associated with increased dementia mortality among the “young-old”. Gender effect varied by age.

Conclusion

The difference in strengths of association of various factors with dementia mortality among different age groups implies the need for a comprehensive framework for community health planning. In particular, strategies for air quality control, usage of greenspace and social space, and activity engagement to reduce vulnerability at all ages are warranted.

Specific Motor and Cognitive Performances Predict Falls during Ward-Based Geriatric Rehabilitation in Patients with Dementia

The aim of this study was to identify in-hospital fall risk factors specific for multimorbid hospitalized geriatric patients with dementia (PwD) during hospitalization. Geriatric inpatients during ward-based rehabilitation (n = 102; 79.4% females; 82.82 (6.19) years of age; 20.26 (5.53) days of stay) were included in a comprehensive fall risk assessment combining established clinical measures, comprehensive cognitive testing including detailed cognitive sub-performances, and various instrumented motor capacity measures as well as prospective fall registration. A combination of unpaired t-tests, Mann-Whitney-U tests, and Chi-square tests between patients with ("in-hospital fallers") and without an in-hospital fall ("in-hospital non-fallers"), univariate and multivariate regression analysis were used to explore the best set of independent correlates and to evaluate their predictive power. In-hospital fallers (n = 19; 18.63%) showed significantly lower verbal fluency and higher postural sway (p < 0.01 to 0.05). While established clinical measures failed in discriminative as well as predictive validity, specific cognitive sub-performances (verbal fluency, constructional praxis, p = 0.01 to 0.05) as well as specific instrumented balance parameters (sway area, sway path, and medio-lateral displacement, p < 0.01 to 0.03) significantly discriminated between fallers and non-fallers. Medio-lateral displacement and visuospatial ability were identified in multivariate regression as predictors of in-hospital falls and an index combining both variables yielded an accuracy of 85.1% for fall prediction. Results suggest that specific cognitive sub-performances and instrumented balance parameters show good discriminative validity and were specifically sensitive to predict falls during hospitalization in a multimorbid patient group with dementia and an overall high risk of falling. A sensitive clinical fall risk assessment strategy developed for this specific target group should include an index of selected balance parameters and specific variables of cognitive sub-performances.

Tailored Exercise and Home Hazard Reduction Program for Fall Prevention in Older People With Cognitive Impairment: The i-FOCIS Randomized Controlled Trial

Background

The evidence to support effective fall prevention strategies in older people with cognitive impairment (CI) is limited. The aim of this randomized controlled trial (RCT) was to determine the efficacy of a fall prevention intervention in older people with CI.

Method

RCT involving 309 community-dwelling older people with CI. The intervention group (n = 153) received an individually prescribed home hazard reduction and home-based exercise program during the 12-month study period. The control group (n = 156) received usual care. The primary outcome was rate of falls. Secondary outcomes included faller/multiple faller status, physical function, and quality of life.

Results

Participants’ average age was 82 years (95% CI 82–83) and 49% were female. There was no significant difference in the rate of falls (incidence rate ratio [IRR] 1.05; 95% confidence interval [95% CI] 0.73–1.51). A sensitivity analysis, controlling for baseline differences and capping the number of falls at 12 (4 participants), revealed a nonsignificant reduction in fall rate in the intervention group (IRR 0.78; 95% CI 0.57–1.07). Analyses of secondary outcomes indicated the intervention significantly reduced the number of multiple fallers by 26% (RR 0.74; 95% CI 0.54–0.99) when adjusting for baseline differences. There was a differential impact on falls in relation to physical function (interaction term p-value = .023) with a significant reduction in fall rate in intervention group participants with better baseline physical function (IRR 0.60; 95% CI 0.37–0.98). There were no significant between-group differences for other secondary outcomes.

Conclusions

This intervention did not significantly reduce the fall rate in community-dwelling older people with CI. The intervention did reduce the fall rate in participants with better baseline physical function.

Frailty and risk of re-hospitalisation and mortality for aged care residents following a fall injury hospitalisation

OBJECTIVES

To examine the role of frailty in risk of re-hospitalisation and mortality for aged care residents following a fall injury hospitalisation.

METHODS

Retrospective analysis of linked hospitalisation and aged care data of adults aged ≥65 years residing in aged care. A semi-competing risk analysis examined risk of hospital readmission.

RESULTS

Residents who had intermediate or high frailty, who were aged 70-79 or 80-89 years, who had 1-2 or ≥3 comorbidities, sustained a hip fracture, and who had either low, moderate or high complex health-care requirements had a higher risk of being readmitted to hospital. Frailty was not associated with mortality for those with no hospital readmission or mortality after readmission.

CONCLUSION

Frailty is an important prognostic factor associated with readmission for residents of aged care hospitalised for a fall injury. Frailty screening could assist to identify people at a high risk of re-hospitalisation following a fall injury.

Scale-up of the Stepping On fall prevention program amongst older adults in NSW: Program reach and fall-related health service use

ISSUE ADDRESSED

We describe the reach of the scale-up of Stepping On, a fall prevention program targeting community-dwellers aged ≥65 years in NSW, along with fall-related ambulance service use and fall-related hospitalisations after scale-up.

METHODS

Data on program provision were received from Local Health Districts. Routinely collected fall-related ambulance usage and hospital admissions in NSW residents aged ≥65 years between 2009 and 2015 were compared within Statistical Local Areas prior to and following the implementation of Stepping On using multilevel models.

RESULTS

Between 2009 and 2014 the program was delivered in 1077 sites to 10 096 older adults. Rates of fall-related ambulance use and hospital admissions per 100-person-years were 1-2 in people aged 66-74, 4-5 in people aged 75-84 and 12-13 in people aged ≥85. These rates increased over time (P < .001). The interaction between time and program delivery was not significant for fall-related ambulance use or hospital admissions. The time-related increase in fall-related ambulance usage in people aged 75-84 years may have been moderated by the Stepping On program (rate ratio 0.97, 95% CI 0.93-1.00, P = .045).

CONCLUSIONS

There was no indication of a reduced rate of fall-related ambulance use or hospital admissions across the entire sample. Ambulance call-outs for falls in people aged 75-84 years may have reduced following program participation. SO WHAT?: Program scale-ups need to reach a large proportion of the target population with a focus on those groups contributing most to fall-related health service utilisation. Linking individual participants' health data as part of large-scale evaluations may provide better insights into program outcomes.

Binocular Vision, Visual Function, and Pupil Dynamics in People Living With Dementia and Their Relation to the Rate of Cognitive Decline and Structural Changes Within the Brain: Protocol for an Observational Study

BACKGROUND

Visual impairment is a common comorbidity in people living with dementia. Addressing sources of visual difficulties can have a significant impact on the quality of life for people living with dementia and their caregivers. Depth perception problems are purportedly common in dementia and also contribute to falls, visuomotor task difficulties, and poorer psychosocial well-being. However, depth perception and binocular vision are rarely assessed in dementia research. Sleep fragmentation is also common for people living with dementia, and binocular cooperation for depth perception can be affected by fatigue. Pupillary responses under cognitive load also have the potential to be a risk marker for cognitive decline in people living with dementia and can be combined with the above measures for a comprehensive evaluation of clinical visual changes in people living with dementia and their relation to changes in cognitive status, sleep quality, and cortical structure or function.

OBJECTIVE

This study aims to characterize the nature of clinical visual changes and altered task-evoked pupillary responses that may occur in people living with dementia and evaluate whether these responses relate to changes in cognitive status (standardized Mini Mental State Examination [MMSE] score), Pittsburgh sleep quality index, and cortical structure or function.

METHODS

This proposed exploratory observational study will enroll ≤210 people with recently diagnosed dementia (within the last 24 months). The following parameters will be assessed on 3 occasions, 4 months apart (plus or minus 2 weeks): visual function (visual acuity and contrast sensitivity), binocular function (motor fusion and stereopsis), task-evoked pupillary responses (minimum and maximum pupil size, time to maximum dilation, and dilation velocity), cognitive status (MMSE score), and sleep quality (Pittsburgh Sleep Quality Index). A subset of patients (n=30) with Alzheimer disease will undergo structural and functional magnetic resonance imaging at first and third visits, completing a 10-day consensus sleep diary to monitor sleep quality, verified by sleep actimetry.

RESULTS

This research was funded in February 2018 and received National Health Service Research Ethics Committee approval in September 2018. The data collection period was from October 1, 2018, to November 30, 2019. A total of 24 participants were recruited for the study. The data analysis is complete, with results expected to be published before the end of 2020.

CONCLUSIONS

Findings will demonstrate how often people with dementia experience binocular vision problems. If frequent, diagnosing and treating them could improve quality of life by reducing the risk of falls and fine visuomotor task impairment and by relieving psychosocial anxiety. This research will also demonstrate whether changes in depth perception, pupillary responses, and quality of vision relate to changes in memory or sleep quality and brain structure or function. If related, these quick and noninvasive eye tests help monitor dementia. This would help justify whether binocular vision and pupillary response testing should be included in dementia-friendly eye-testing guidelines.

Hospitalization and discharge routes of elderly hip fracture patients with and without dementia: a nationwide cross-sectional exploratory study using the Japanese Diagnostic Procedure Combination database

PURPOSE

The characteristics of elderly hip fracture patients in acute care hospitals were analyzed based on hospitalization and discharge route and the presence or absence of a dementia diagnosis.

METHODS

The study was conducted as a cross-sectional exploratory study using data from the Diagnosis Procedure Combination database in Japan from April 2014 to March 2016. Patients aged 65 years or older who had surgery for a hip fracture were identified. We subsequently extracted patients whose home, medical institution (including convalescent rehabilitation wards), or elderly care facility was both the admission and discharge route. A total of 105 122 patients were included.

RESULTS

19% of patients were diagnosed with dementia. Patients with dementia had a shorter length of acute care hospital stay than those without dementia. The hospitalization route for dementia patients was 51% at home and 40% at a care facility. Dementia patients were discharged to hospital and care facilities at 41% each. Nearly all patients received hospital-based postoperative rehabilitation regardless of dementia but patients with dementia had lower gains in activities of daily living.

CONCLUSION

Hip fracture patients with dementia have less opportunity for continuous hospital-based rehabilitation and need an environment that allows for continuous elderly care facility-based and community-based rehabilitation.IMPLICATIONS FOR REHABILITATIONIn Japan, an aging society, one in five elderly patients undergoing hip fracture surgery was diagnosed with dementia.Many hip fracture patients with dementia have a shorter length of hospital stay and may have fewer opportunities to change hospitals to receive rehabilitation.It is necessary to establish an ongoing and proactive community- and elderly care facility-based rehabilitation system for patients with hip fracture with dementia after acute care hospital discharge.

Health outcomes of patients with dementia in acute care settings-A systematic review

BACKGROUND

An ageing population has resulted in increased numbers of people with dementia attending acute care services; however, the impact of hospitalisation on this population is uncertain.

PURPOSE

This systematic review aimed to synthesise the available evidence on adverse health outcomes for people with dementia in acute care settings.

METHODS

A systematic search of CINAHL, PubMed, MEDLINE, EMBASE and Scopus databases for primary research articles in English language, published from 2000 to 2017, was conducted. A protocol for the review was registered on the PROSPERO database.

RESULTS

The initial search identified 5,520 records. Following removal of duplicates and assessment against inclusion criteria, 13 studies were included in the final review. Findings identify associations between patients with dementia, longer length of hospital stay and higher mortality in some situations. Heterogeneity across studies in data reporting and outcomes prevented meta-analysis; therefore, results are presented narratively.

CONCLUSIONS

Certainty of findings from this review is impacted by variation in patient condition and data reporting. Additional rigorous studies on health outcomes for people with dementia during acute hospitalisation will contribute to the evidence.

IMPLICATIONS FOR PRACTICE

These findings along with further research examining outcomes for patients with dementia in acute care settings will inform provision of safer, quality care and optimal health outcomes for this vulnerable population.

White matter hyperintensities are associated with falls in older people with dementia

White Matter Hyperintensities (WMHs) are associated with impaired gait, balance and cognition and increased fall risk in cognitively healthy older people. However, few studies have examined such relationships in older people with dementia. Understanding the role of WMHs in falls may assist in developing effective fall prevention strategies. We investigated the relationship between baseline WMHs, cognitive and sensorimotor function and prospective falls in older people with dementia. Twenty-eight community-dwelling older people with mild-moderate dementia (MMSE 11-23; ACE-R < 83) underwent magnetic resonance imaging and assessment of sensorimotor and cognitive (global and processing speed) function at baseline. WMHs, were quantified using a fully automated segmentation toolbox, UBO Detector ( https://cheba.unsw.edu.au/group/neuroimaging-pipeline ). Falls were ascertained prospectively for 12-months using monthly calendars with the assistance of carers. The median age of the participants was 83 years (IQR 77-86); 36% were female; 21 (75%) fell during follow-up. Using Generalized Linear Models, larger volumes of total WMHs were found to be significantly associated with poorer global cognitive and sensorimotor function. Using modified Poisson regression, total, periventricular and deep WMHs were each associated with future falls while controlling for age, sex, intracranial volume and vascular risk. Each standard deviation increase in total and periventricular WMH volume resulted in a 33% (RR 1.33 95%CI 1.07-1.66) and 30% (RR 1.30 95%CI 1.06-1.60) increased risk of falling, respectively. When the deep WMH volume z-scores were dichotomized at the median, individuals with greater deep WMH volumes had an 81% (RR 1.81 95% CI 1.02-3.21) increased risk of falling. WMHs were associated with poorer sensorimotor and cognitive function in people with dementia and total, periventricular and deep WMHs were associated with falls. Further research is needed to confirm these preliminary findings and explore the impact of vascular risk reduction strategies on WMHs, functional performance and falls.

Structure and process of dementia care and patient outcomes after hip surgery in elderly people with dementia: A retrospective observational study in Japan

BACKGROUND

Japan introduced the financial incentives for dementia special care at hospitals in the fee schedule in April 2016.

OBJECTIVE

To investigate whether the financial incentives for dementia special care contributed to better patient outcomes after hip surgery for older adults with dementia.

DESIGN

Retrospective observational study using the Diagnosis Procedure Combination database and the Reporting on medical functions of hospital beds data.

SETTING

Acute care hospitals adopting the Diagnosis Procedure Combination system in Japan.

PARTICIPANTS

A total of 20,393 eligible patients aged 65 years or older with dementia who underwent hip surgeries and discharged from 405 hospitals from April 2016 to March 2017.

METHODS

There are two levels of dementia care quality categories in the financial incentives for dementia special care as follows: Type 1 requires a multidisciplinary team with geriatric and dementia care expertise and Type 2 requires to assign trained nurses who underwent dementia training at every general ward. The outcomes were in-hospital mortality, readmission within 30 days, and length of hospital stay. We performed generalized estimating equation model or logistic generalized estimating equation models adjusting for individual and hospital characteristics.

RESULTS

Among the 405 hospitals, the numbers of hospitals without dementia care incentive, those with Type 1, and those with Type 2 were 207, 99, and, 99, respectively. Overall, the prevalence of in-hospital death and readmission within 30 days was 2.01% and 2.70%, respectively. Overall, the mean (standard deviation, SD) length of hospital stay was 32.0 (20.0) days. There were no significant associations between dementia special care and in-hospital mortality in Type 1 (adjusted OR [odds ratio] =0.87, 95% confidence interval [CI] = 0.66-1.16) and Type 2 (adjusted OR = 1.18, 95% CI = 0.92-1.52), and readmission within 30 days in Type 1 (adjusted OR = 1.11, 95% CI = 0.89-1.38) and Type 2 (adjusted OR = 1.03, 95% CI = 0.83-1.29). Length of hospital stay was not significantly different among hospitals with and without incentive, Type 1 (coefficient -0.23, 95% CI = -2.64-2.18.), and Type 2 (coefficient 0.87, 95% CI = -1.54-3.28). An increase in patient-to-nurse ratio was significantly associated with 2.25 days longer length of hospital stay (95% CI 1.00-3.51).

CONCLUSION

Dementia care incentive was not associated with better outcomes in elderly with dementia who underwent hip surgery in Japan, but the worse nurse workload was associated with longer length of hospital stay. Further long-term assessment is necessary.

[Dementia-specific characteristics of patients with fall-related femur fractures : A case study based on routine hospital data of patients with unspecified dementia]

BACKGROUND

A fall-related femur fracture is one of the most frequent reasons for hospital admission of patients with dementia. The aim of the study was to identify dementia-specific characteristics of patients with fall-related femur fractures and additionally an unspecified dementia in order to gain further knowledge about this particular patient group.

METHODS

A descriptive explorative case study with a single case-embedded design based on routine hospital data from a university hospital was performed. A total number of 34 patient records from 2015 were analyzed. In the embedded unit of analysis I the data of selected items of the nursing assessment AcuteCare (ePA-AC©) were descriptively analyzed for the time of admission and discharge. In the embedded unit of analysis II a summarizing inductive content analysis was conducted.

RESULTS

The results of the embedded unit of analysis I showed that this patient group is characterized by a high need for care, changes of cognition and behavioral symptoms. The status of cognition, behavior and reciprocity as well as the self-care index stagnated or deteriorated in many patients from admission to discharge. The embedded unit of analysis II identified observable (social)behavior, (non)compliance and orientation as central dementia-specific characteristics.

CONCLUSION

The results reflect the complexity of the care situation of patients with unspecified dementia in acute care hospitals. The results showed that a higher awareness for this particular patient group is needed to improve outcomes.

Fracture Experiences and Long-Term Care Initiation among Older Population: Analysis of Korean National Health Insurance Service-Senior Cohort Study

BACKGROUND

Long-term care is a burden on individuals, families, and society. It is important to find ways to delay the onset of disability to lessen the burden of long-term care in aging societies. Fracture is one of the risk factors that affect physical functions and make older people dependent. This study aimed to examine how much more often older adults who experienced fractures initiated long-term care compared to those who did not, and whether the risk of entering long-term care differed significantly by fracture site.

METHODS

The analyses included insurants aged 65 years and over from the Korean National Health Insurance Service-senior cohort study (2002-2013). Cox proportional hazard models were used to calculate the hazard ratios of the first certification of initiation of long-term care after fracture, by fracture site, and for multiple recurrent fractures.

RESULTS

The incidence rate of initial long-term care beneficiaries was approximately 2.5 times higher when older people had experienced fractures; these individuals entered long-term care beneficiary status 3 years earlier compared to those who had no fracture events. Lower extremity fracture and multiple recurrent fractures more than doubled the risk for long-term care.

CONCLUSION

Additional attention to fracture sites in prevention and rehabilitation settings is warranted to reduce disability and the related long-term care burden.

The Impact of Hospitalization on Readmission, Institutionalization, and Mortality of People with Dementia: A Systematic Review and Meta-Analysis

BACKGROUND

People with dementia (PwD) are at a high risk of hospitalization. Hospitals are often not adequately equipped for PwD and discharges often come unexpected. Therefore, PwD are at a risk of adverse outcomes. However, information about those outcomes is rare but crucial for the development of preventive strategies.

OBJECTIVES

To conduct a quantitative systematic review and meta-analyses on the impact of a hospitalization on readmission, institutionalization, and mortality in PwD. To identify factors associated with these outcomes.

METHODS

PubMed, CENTRAL, and ScienceDirect were searched for studies including terms for dementia, hospital, readmission, institutionalization, and mortality. Relevant were assessed by a quality criteria sheet. Results were summarized in a table. Meta-analysis was conducted with Review Manager 5.3.

RESULTS

The search yielded 1,108 studies; 20 fulfilled the inclusion criteria and 10 studies were eligible for meta-analyses. The incidence and relative risk (RR) of mortality (RR 1.74 CI95 % 1.50, 2.05) and institutionalization (RR: 2.16 CI95 % 1.31, 3.56) of PwD was significantly higher when compared to people without dementia. Results according to readmission rate were inconsistent. Factors significantly associated with the examined adverse outcomes were severity of dementia, number of medications, and deficits in daily living activities.

CONCLUSION

Hospitalization of PwD lead to adverse outcomes. An improvement in the identification of and care for PwD in the acute setting as well as in after care in the community setting, especially in the interface between both settings, is required to prevent adverse outcomes in hospitalized PwD.

Incidence of head injury and traumatic brain injury among people with Alzheimer’s disease

Background

Injuries caused by falling are a major health concern among older population. For older people, falls are the leading cause of head injuries; especially, persons with cognitive disorders have an increased risk of falling.

Objective

To compare the incidence of head injury and traumatic brain injury (TBI) among persons with Alzheimer’s disease (AD) with persons without AD.

Methods

This register-based study was conducted on a nationwide cohort, which includes all community-dwelling persons diagnosed with AD in Finland in 2005–2011. Persons with previous head injuries were excluded, leaving 67 172 persons with AD. For each person with AD, a matching person without AD and previous head injury were identified with respect to age, sex and university hospital district. The Cox proportional hazard model and competing risk analyses were used to estimate HR for head injury and TBI.

Results

Persons with AD had 1.34-fold (95% CI 1.29 to 1.40) risk of head injuries and 1.49-fold (95% CI 1.40 to 1.59) risk of TBIs after accounting for competing risks of death and full adjustment by socioeconomic status, drug use and comorbidities.

Conclusion

Persons with AD are more likely to have a head injury or TBI incident than persons without AD.

Length of hospital stay and dementia: A systematic review of observational studies

OBJECTIVE

Hospitalizations of people with dementia (PWD) are often accompanied by complications or functional loss and can lead to adverse outcomes. Unsystematic findings suggest an influence of comorbidities on the extent of differences in the length of hospital stay (LOS). This systematic review aimed to identify and evaluate all studies reporting LOS in PWD as compared to PwoD in general hospitals.

METHODS

A systematic review of observational studies using PubMed and ISI Web of Knowledge. Inclusion criteria comprised original studies written in English or German, assessment of diagnosis of dementia, measurement of LOS, and comparison of people with and without dementia.

RESULTS

Fifty-two of 60 studies reported a longer hospitalization time for PWD compared to PwoD. The extent of the difference in LOS varied between and within countries as well as by type of primary morbidity (eg, injuries, cardiovascular diseases). The range of the LOS difference for studies without restriction to a primary morbidity was -2 to +22 days after matching or adjustment for a variable number and selection of potentially relevant covariates. For studies with injuries/fractures/medical procedures and infectious/vascular disease as the primary morbidity, the range was -2.9 to +12.4 and -11.2 to +21.8 days, respectively.

CONCLUSIONS

The majority of studies reported a longer hospitalization of PWD compared to PwoD. Length of hospital stay seems to be influenced by a variety of medical, social, organizational factors, including reasons for hospital admission, whose role should be explored in detail in further research.

Integrated care for adults with dementia and other cognitive disorders

The importance of better care integration is emphasized in many national dementia plans. The inherent complexity of organizing care for people with dementia provides both the justification for improving care integration and the challenges to achieving it. The prevention, detection, and early diagnosis of cognitive disorders mainly resides in primary care, but how this is best integrated within the range of disorders that primary care clinicians are expected to screen is unclear. Models of integrated community dementia assessment and management have varying degrees of involvement of primary and specialist care, but share an emphasis on improving care coordination, interdisciplinary teamwork, and personalized care. Integrated care strategies in acute care are still in early development, but have been a focus of investigation in the past decade. Integrated care outreach strategies to reduce transfers from long-term residential care to acute care have been consistently effective. Integrated long-term residential care includes considerations of end-of-life care. Future directions should include strategies for training and education, early detection in anticipation of disease modifying treatments, integration of technological developments into dementia care, integration of dementia care into general health and social care, and the encouragement of a dementia-friendly society.

Determinants of hospitalization and length of stay among people with dementia - An analysis of statutory health insurance claims data

OBJECTIVE

Dementia is a crucial challenge in acute care hospitals. Using a retrospective claims data cohort, this paper explores dementia patients' acute hospitalization rates, risk factors, and length of stay.

METHODS

The study used claims data from AOK PLUS, the largest statutory health insurance service (SHI) in Saxony, a federal state of Germany. The analysis included 61,239 people with dementia and 183,477 control subjects, all 65 years and older. Control subjects were age, gender, and regionally matched in a 1:3 ratio. Negative binomial hurdle regression was used to compare differences in hospitalization for the year 2014.

RESULTS

People with dementia had 1.49 times higher adjusted odds of being hospitalized at least once (95% confidence interval [CI], 1.46-1.52). Among those individuals hospitalized at least once, dementia increased the number of readmissions by 18% (95% CI, 1.15-1.20). Dementia patients also had a 1.74 times higher odds for at least one emergency admission compared to individuals without dementia (95% CI, 1.70-1.78). Dementia patients' admission risk factors included having care dependency, being recently diagnosed with dementia and living outside a metropolitan region. The increased length of stay for people with dementia per year was mainly attributable to higher admission rates.

CONCLUSIONS

Dementia patients are at higher risk for hospitalization, especially if they live outside the metropolitan region. Healthcare systems need to respond to the challenges resulting from the predicted demographic developments and increasing burden of dementia in the general population.

Dementia

Dementia is a syndrome seen most commonly in older people and characterized by a decline in cognitive performance which impacts on the person's ability to function. There are approximately 47 million people worldwide with dementia and there are 10 million new cases every year. It is a major cause of disability and dependence and impacts on the physical, psychologic, and social well-being of families and carers. Alzheimer's disease is the most common form of dementia. Gait and balance impairments are common in people with dementia and contribute to the significantly elevated risk of falls. Older people with dementia are at increased risk of injury, institutionalization, hospitalization, morbidity, and death after a fall. There is preliminary evidence, predominantly from relatively small studies, that falls and disability can be prevented in this population. However, more good-quality research is needed, both to provide some certainty around the existing evidence base as well as to explore alternate approaches to prevention, including combined cognitive-motor training and cognitive pharmacotherapy.

Trauma Consults by Geriatricians: Looking Into the Black Box

The conceptual framework, targeting of older adults, and content of a targeted geriatric trauma consult (GTC) performed by geriatricians at a Level 1 trauma center are highlighted. The GTC is designed to optimize patient care through comprehensive assessment and to interrupt the disablement process. In a performance improvement study, fellowship-trained and certified geriatricians conducted the GTC in 98 patients ranging in age from 68 to 100 years. Most common recommendations by the geriatricians were for transitions of care (e.g., home health, skilled nursing facility, hospice), changes in medications (e.g., antihypertensives, antidepressants/antipsychotics), advanced care planning, and specialist referral. Targeted GTC performed by a geriatrician is an efficient approach to comanagement of complex older trauma patients, in contrast to mandated geriatric team consultation. In settings of value-based care, GTC by a geriatrician has potential to reduce patient disability and health care costs compared with usual care of older trauma patients.

Cognitive enhancers associated with decreased risk of injury in patients with dementia: a nationwide cohort study in Taiwan

This study aimed to investigate the associations among dementia, psychotropic medications and the risk of overall injuries. In this nationwide matched cohort study, a total of 144 008 enrolled patients ≥age of 50, with 36 002 study subjects who suffered from dementia and 108 006 controls matched for sex and age, from the Inpatient Dataset, for the period 2000-2010 in Taiwan were selected from the National Health Insurance Research Database, according to International Classification of Diseases, 9th Revision, Clinical Modification. When adjusting for the confounding factors, a Cox proportional hazards analysis was used to compare the risk of developing psychiatric disorders during the 10 years of follow-up. Of the study subjects, 6701 (18.61%) suffered injury when compared with 20 919 (19.37%) in the control group. The Cox regression analysis revealed that the study subjects were more likely to develop an injury (HR: 2.294, 95% CI=2.229 to 2.361, P<0.001) after adjusting for sex, age, monthly income, urbanization level, geographic region, and comorbidities. Psychotropic medications in the subjects with dementia were associated with the risk of injury (adjusted HR=0.217, 95% CI: 0.206 to 0.228, P<0.001). Cognitive enhancers, including acetylcholinesterase inhibitors and memantine, were associated with the risk of injury in the study subjects after being adjusted for all comorbidities and medications (adjusted HR=0.712(95% CI=0.512 to 0.925, P<0.01)). In conclusion, patients who suffered dementia had a higher risk of developing injury, and the cognitive enhancers were associated with the decreased risk of injury.

Risk factors associated with residential aged care, respite and transitional aged care admission for older people following an injury-related hospitalisation

OBJECTIVES

To identify factors associated with admission to residential aged care (RAC), respite RAC and transitional care (TC) for older individuals following an injury hospitalisation.

METHOD

A retrospective analysis was conducted of individuals aged ≥65 years who had an injury hospitalisation and who were admitted to RAC during 1 July 2008 and 30 June 2013 in New South Wales, Australia. Multinominal logistic regression was used to examine the factors associated with admissions to aged care services compared to returning to the community.

RESULTS

Of 191,301 injury hospitalisations, 41,085 (21.5%) individuals either returned or were new admissions to long-term or respite RAC and 3,218 individuals were admitted to TC. Older individuals newly admitted to long-term RAC were four times more likely (OR: 4.36; 95%CI 4.15-4.57), those admitted to respite RAC were twice as likely (OR: 2.37; 95%CI 2.21-2.54) and people admitted to TC were less likely (OR: 0.60; 95%CI 0.53-0.68) to have dementia compared to individuals who returned to the community. Overall, individuals who were admitted to long-term or respite RAC had a higher likelihood of experiencing limitations associated with their physical, cognitive or social abilities, with individuals admitted to TC having a higher likelihood of issues with hygiene and mobility, compared to individuals returning to the community.

CONCLUSION

Understanding the profile and predictive risk factors for injured older individuals using RAC (long-term, respite or TC services) can inform current and future aged care service resource use needs and can be used to understand factors associated with service use.

Informed Consent to Research with Cognitively Impaired Adults: Transdisciplinary Challenges and Opportunities

Due to issues related to informed research consent, older adults with cognitive impairments are often excluded from high-quality studies that are not directly related to cognitive impairment, which has led to a dearth of evidence for this population. The challenges to including cognitively impaired older adults in research and the implications of their exclusion are a transdisciplinary issue. The ethical challenges and logistical barriers to conducting research with cognitively impaired older adults are addressed from the perspectives of three different fields-social work, emergency medicine, and orthopaedic surgery. Issues related to funding, study design, intervention components, and outcomes are discussed through the unique experiences of three different providers. A fourth perspective-medical research ethics-provides alternatives to exclusion when conducting research with cognitively impaired older adults such as timing, corrective feedback and plain language, and capacity assessment and proxy appointments. Given the increasing aging population and the lack of evidence on cognitively impaired older adults, it is critical that researchers, funders, and institutional review boards not be dissuaded from including this population in research studies.

Risk Factors for In-Hospital Complications of Fall-Related Fractures among Older Chinese: A Retrospective Study

Purpose. The aim of this study was to investigate the risk factors and the efficacy of the preventive measurements for the in-hospital complications of fall-related fractures. Methods. The data on older Chinese patients with fall-related fractures were collected, including information on the patients, diseases, and preventive measurements. The potential risk factors for the in-hospital complications included health status on admission, comorbidity, fractures, preventive measures of the complications, and drugs use for the comorbidity. After univariate analyses, multivariate logistic regression analyses were applied to investigate the impact of the potential risk factors on the number of the complications and each individual complication, respectively, and the efficacy of the preventive measurements. Results. A total of 525 male and 1367 female were included in this study. After univariate analyses, multiple logistic regression showed that dementia, pneumonia, antidepressant, postural hypotension, and cerebral infarction could increase the incidence and number of comorbidities. Meanwhile, dementia has shown the strongest association with each individual complication. Conclusions. Different combinations of comorbidity, medication use, and preventive measurements were related to the in-hospital complications of fall-related fractures. Dementia emerged as the most important risk factor for these complications, while most of the preventive measurements could not reduce their incidences.
