Predictors of institution admission in the year following acute hospitalisation of elderly people

Age Moderates Differences in Performance on the Instrumented Timed Up and Go Test Between People With Dementia and Their Informal Caregivers

BACKGROUND AND PURPOSE

The instrumented Timed Up and Go test (iTUG) affords quantification of the subelements of the Timed Up and Go test to assess fall risk and physical performance. A miniature sensor applied to the back is able to capture accelerations and velocities from which the subelements of the iTUG can be quantified. This study is the first to compare iTUG performance between people with dementia (PWD) and their age-matched caregivers. The aims of this study were to explore how age moderates the differences in performance on the iTUG between PWD and their informal caregivers.

METHODS

Eight-three community-dwelling older PWD and their informal caregivers were recruited for this cross-sectional, observational study. Participants were grouped by age: younger than 70 years, 70 to 79 years, and 80 years and older. Participants wore an inertial sensor while performing the iTUG in their home. The performance of the subelements sit-to-stand, walking, and turning were captured through an algorithm converting accelerations and velocities into performance metrics such as duration and peak velocity. Performance for PWD was compared with caregivers for each age-matched group, and multiple regression models incorporating age, gender, and presence or absence of dementia were computed.

RESULTS

People with dementia took longer to turn in the younger than 70-year group, suggesting this may be an early indicator of functional decline in this age group. People with dementia took longer to complete the whole iTUG compared with caregivers in the 70- to 79-year-old group. In the 80+-year-old group, PWD took longer to complete both walking phases, sit-to-stand, and the full iTUG along with displaying slower turning velocity. Multiple regression models illustrated that gender failed to contribute significantly to the model, but age and presence of dementia explained around 30% of the variance of time to complete walking phases, total iTUG, and turning velocity.

CONCLUSIONS

Differences were evident in performance of the iTUG between PWD and caregivers even after controlling for age. Age moderates the differences observed in performance.

Understanding health-care outcomes of older people with cognitive impairment and/or dementia admitted to hospital: a mixed-methods study

Background

Cognitive impairment is common in older people admitted to hospital, but previous research has focused on single conditions.

Objective

This project sits in phase 0/1 of the Medical Research Council Framework for the Development and Evaluation of Complex Interventions. It aims to develop an understanding of current health-care outcomes. This will be used in the future development of a multidomain intervention for people with confusion (dementia and cognitive impairment) in general hospitals. The research was conducted from January 2015 to June 2018 and used data from people admitted between 2012 and 2013.

Design

For the review of outcomes, the systematic review identified peer-reviewed quantitative epidemiology measuring prevalence and associations with outcomes. Screening for duplication and relevance was followed by full-text review, quality assessment and a narrative review (141 papers). A survey sought opinion on the key outcomes for people with dementia and/or confusion and their carers in the acute hospital (n = 78). For the analysis of outcomes including cost, the prospective cohort study was in a medical admissions unit in an acute hospital in one Scottish health board covering 10% of the Scottish population. The participants (n = 6724) were older people (aged ≥ 65 years) with or without a cognitive spectrum disorder who were admitted as medical emergencies between January 2012 and December 2013 and who underwent a structured nurse assessment. ‘Cognitive spectrum disorder’ was defined as any combination of delirium, known dementia or an Abbreviated Mental Test score of < 8 out of 10 points. The main outcome measures were living at home 30 days after discharge, mortality within 2 years of admission, length of stay, re-admission within 2 years of admission and cost.

Data sources

Scottish Morbidity Records 01 was linked to the Older Persons Routine Acute Assessment data set.

Results

In the systematic review, methodological heterogeneity, especially concerning diagnostic criteria, means that there is significant overlap in conditions of patients presenting to general hospitals with confusion. Patients and their families expect that patients are discharged in the same or a better condition than they were in on admission or, failing that, that they have a satisfactory experience of their admission. Cognitive spectrum disorders were present in more than one-third of patients aged ≥ 65 years, and in over half of those aged ≥ 85 years. Outcomes were worse in those patients with cognitive spectrum disorders than in those without: length of stay 25.0 vs. 11.8 days, 30-day mortality 13.6% vs. 9.0%, 1-year mortality 40.0% vs. 26.0%, 1-year mortality or re-admission 62.4% vs. 51.5%, respectively (all p < 0.01). There was relatively little difference by cognitive spectrum disorder type; for example, the presence of any cognitive spectrum disorder was associated with an increased mortality over the entire period of follow-up, but with different temporal patterns depending on the type of cognitive spectrum disorder. The cost of admission was higher for those with cognitive spectrum disorders, but the average daily cost was lower.

Limitations

A lack of diagnosis and/or standardisation of diagnosis for dementia and/or delirium was a limitation for the systematic review, the quantitative study and the economic study. The economic study was limited to in-hospital costs as data for social or informal care costs were unavailable. The survey was conducted online, limiting its reach to older carers and those people with cognitive spectrum disorders.

Conclusions

Cognitive spectrum disorders are common in older inpatients and are associated with considerably worse health-care outcomes, with significant overlap between individual cognitive spectrum disorders. This suggests the need for health-care systems to systematically identify and develop care pathways for older people with cognitive spectrum disorders, and avoid focusing on only condition-specific pathways.

Future work

Development and evaluation of a multidomain intervention for the management of patients with cognitive spectrum disorders in hospital.

Previous in-home physiotherapy prevents institutionalization after short-term hospitalization in community-dwelling older dependent people

AIMS

Short-term hospitalization of community-dwelling older dependent people in a geriatric acute care unit is sometimes needed to treat an acute health problem. Serious loss of independence can lead to difficulties in maintaining home care and is followed, at hospital discharge, to institutionalization in a long-term care home. We investigated the variables, particularly those related to the paramedical staff at home, predicting a return home or an institutionalization at hospital discharge.

METHODS

Retrospective observational study of 398 sixty and more year-old patients, living at home, having a natural caregiver, and hospitalized in an acute care unit of the State Geriatric Center.

RESULTS

289 (72.6%) patients returned home, 101 (25.3%) were admitted in a long-term care home, and 8 (2%) died. Independent predictors of institutionalization were length of stay in the acute care unit [adjusted OR (AOR) = 1.102, P < 0.001], disruptive behavioral and psychological symptoms of dementia (BPSD, AOR = 1.827, P = 0.039), caregiver burden (AOR = 1.976, P = 0.038), moderately severe-to-severe cognitive impairment (AOR = 2.121, P = 0.011), and living alone with a close or a remote caregiver (AOR = 2.620 and 4.446, P = 0.003 and 0.001, respectively). In-home physiotherapy was independently associated (AOR = 0.393, P = 0.002) with a lower risk of institutionalization.

CONCLUSION

In-home physiotherapy should be recommended to community-dwelling older dependent people, especially if they are living alone and/or if they present disruptive BPSD and/or moderately severe-to-severe cognitive impairment.

Randomised Controlled Trial Of The Effect Of Tai Chi On Postural Balance Of People With Dementia

Purpose

To investigate the effect of Tai Chi exercise on postural balance among people with dementia (PWD) and the feasibility of a definitive trial on falls prevention.

Patients and methods

Dyads, comprising community-dwelling PWD and their informal carer (N=85), were randomised to usual care (n=43) or usual care plus weekly Tai Chi classes and home practice for 20 weeks (n=42). The primary outcome was the timed up and go test. All outcomes for PWD and their carers were assessed six months post-baseline, except for falls, which were collected prospectively over the six-month follow-up period.

Results

For PWD, there was no significant difference at follow-up on the timed up and go test (mean difference [MD] = 0.82, 95% confidence interval [CI] = -2.17, 3.81). At follow-up, PWD in the Tai Chi group had significantly higher quality of life (MD = 0.051, 95% CI = 0.002, 0.100, standardised effect size [ES] = 0.51) and a significantly lower rate of falls (rate ratio = 0.35, 95% CI =0.15, 0.81), which was no longer significant when an outlier was removed. Carers in the Tai Chi group at follow-up were significantly worse on the timed up and go test (MD = 1.83, 95% CI = 0.12, 3.53, ES = 0.61). The remaining secondary outcomes were not significant. No serious adverse events were related to participation in Tai Chi.

Conclusion

With refinement, this Tai Chi intervention has potential to reduce the incidence of falls and improve quality of life among community-dwelling PWD [Trial registration: NCT02864056].

Cost-effectiveness of gastro-resistant risedronate tablets for the treatment of postmenopausal women with osteoporosis in France

The use of gastro-resistant risedronate, a convenient dosing regimen for oral bisphosphonate therapy, seems a cost-effective strategy compared with weekly alendronate, generic risedronate, and no treatment for the treatment of postmenopausal women with osteoporosis in France.

INTRODUCTION

Gastro-resistant (GR) risedronate tablets are associated with improved persistence compared to common oral bisphosphonates but are slightly more expensive. This study assessed its cost-effectiveness compared to weekly alendronate and generic risedronate for the treatment of postmenopausal women with osteoporosis in France.

METHODS

A previously validated Markov microsimulation model was used to estimate the lifetime costs (expressed in €2017) per quality-adjusted life-years (QALY) of GR risedronate compared with weekly alendronate, generic risedronate, and no treatment. Pooled efficacy data for bisphosphonates derived from a previous meta-analysis were used for all treatment options, and persistence data (up to 3 years) were obtained from a large Australian longitudinal study. Evaluation was done for high-risk women 60-80 years of age, with a bone mineral density (BMD) T-score ≤ - 2.5 and/or prevalent vertebral fractures.

RESULTS

In all of the simulated populations, GR risedronate was cost-effective compared to alendronate, generic risedronate, and no treatment at a threshold of €60,000 per QALY gained. In women with a BMD T-score ≤ - 2.5 and prevalent vertebral fractures, the cost per QALY gained of GR risedronate compared to alendronate, generic risedronate, and no treatment falls below €20,000 per QALY gained. In women aged 75 years and older, GR risedronate was even shown to be dominant (more QALYs, less costs) compared to alendronate, generic risedronate, and no treatment.

CONCLUSION

This study provides the first economic results about GR risedronate, suggesting that it represents a cost-effective strategy compared with weekly alendronate and generic risedronate for the treatment of postmenopausal women with osteoporosis in France.

Core elements of the interpersonal care relationship between nurses and older patients without cognitive impairment during their stay at the hospital: A mixed-methods systematic review

BACKGROUND

The fundamental importance of establishing an interpersonal care relationship for quality nursing care has been highlighted. However specific elements of the interpersonal care relationship of importance to older patients in the hospital have not been identified.

OBJECTIVES

The aim of this review was to explore and synthesise research findings regarding the elements of the interpersonal care relationship concept from the perspectives of older patients.

DESIGN

A systematic mixed-methods review.

DATA SOURCES

An extensive search was conducted up until October 2018 for articles without any publication date time limit in PubMed, Web of Science, Cochrane Database of Systematic Reviews and CINAHL.

REVIEW METHODS

Primary studies were included if they concerned patients aged 65 years or older and their perspectives on the elements of the interpersonal care relationship with nurses. Inclusion was limited to patients without cognitive impairment who were admitted to an acute hospital setting. The methodological quality of each study was assessed using the Critical Appraisal Skills Programme for qualitative studies, the Quality Assessment Tool for Quantitative Studies and the Mixed-Methods Appraisal Tool. Thematic analysis was used to structure the results of the included studies.

RESULTS

Of the 7596 studies found, 24 were included in this review. Twenty articles had a qualitative, three a quantitative and one a mixed methods design. Older patients consider dignity and respect as core values that need to be met in the interpersonal care relationship. Five core elements of the interpersonal care relationship were identified to meet these core values: elements related to caring behaviour and attitude, person-centred care, patient participation, communication and situational aspects. These core elements were structured according to three categories, identified in the literature, that determine the quality of the interpersonal care relationship: nurse-, older-patient-related elements and situational aspects.

CONCLUSIONS

The elements identified in this review can guide efforts to define the interpersonal care relationship between older patients and nurses. Nurses should be supported and motivated by education and practice to adapt their behaviour, attitudes and communication to meet older patients' expectations. Hospital management can also encourage nurses to communicate well. Investment in the current organisation of care is needed to improve nurses' work overload and presence. Further research is needed to clarify the underlying processes influencing the experience of the interpersonal care relationship from the perspectives of older patients, nurses, informal caregivers and hospital management.

A randomised controlled trial comparing the effectiveness of tai chi alongside usual care with usual care alone on the postural balance of community-dwelling people with dementia: protocol for the TACIT trial (TAi ChI for people with demenTia)

Background

Falls are a public health issue for the older adult population and more so for people with dementia (PWD). Compared with their cognitively intact peers, PWD are at higher risk of falls and injurious falls. This randomised controlled trial aims to test the clinical and cost effectiveness of Tai Chi to improve postural balance among community-dwelling PWD and to assess the feasibility of conducting a larger definitive trial to reduce the incidence of falls among PWD.

Methods

A 3-centre parallel group randomised controlled trial with embedded process evaluation. One hundred and fifty community-dwelling dyads of a person with dementia and their informal carer will be recruited and assessed at baseline and at six-month follow-up. Dyads will be randomised in a 1:1 ratio to either usual care or usual care plus a Tai Chi intervention for 20 weeks. The Tai Chi intervention will consist of weekly classes (45 min’ Tai Chi plus up to 45 min for informal discussion, with up to 10 dyads per class) and home-based exercises (20 min per day to be facilitated by the carer). Home practice of Tai Chi will be supported by the use of behaviour change techniques with the Tai Chi instructor at a home visit in week 3–4 of the intervention (action planning, coping planning, self-monitoring, and alarm clock reminder) and at the end of each class (feedback on home practice). The primary outcome is dynamic balance measured using the Timed Up and Go test, coinciding with the end of the 20-week intervention phase for participants in the Tai Chi arm. Secondary outcomes for PWD include functional balance, static balance, fear of falling, global cognitive functioning, visual-spatial cognitive functioning, quality of life, and falls. Secondary outcomes for carers include dynamic balance, static balance, quality of life, costs, and carer burden.

Discussion

This trial is the first in the UK to test the effectiveness of Tai Chi to improve balance among PWD. The trial will inform a future study that will be the first in the world to use Tai Chi in a trial to prevent falls among PWD.

Trial registration

NCT02864056.

Hospital outcomes of older people with cognitive impairment: An integrative review

OBJECTIVES

To summarise existing knowledge of outcomes of older hospital patients with cognitive impairment, including the type and frequency of outcomes reported, and the additional risk experienced by this patient group.

METHODS

Integrative literature review. Health care literature databases, reports, and policy documents on key websites were systematically searched. Papers describing the outcomes of older people with cognitive impairment during hospitalisation and at discharge were analysed and summarised using integrative methods.

RESULTS

One hundred four articles were included. A range of outcomes were identified, including those occurring during hospitalisation and at discharge. Older people with a dementia diagnosis were at higher risk from death in hospital, nursing home admission, long lengths of stay, as well as intermediate outcomes such as delirium, falls, dehydration, reduction in nutritional status, decline in physical and cognitive function, and new infections in hospital. Fewer studies examined the relationship of all-cause cognitive impairment with outcomes. Patient and carer experiences of hospital admission were often poor. Few studies collected data relating to hospital environment, eg, ward type or staffing levels, and acuity of illness was rarely described.

CONCLUSIONS

Older people with cognitive impairment have a higher risk of a variety of negative outcomes in hospital. Prevalent intermediate outcomes suggest that changes in care processes are required to ensure maintenance of fundamental care provision and greater attention to patient safety in this vulnerable group. More research is required to understand the most appropriate ways of doing this and how changes in these care processes are best implemented to improve hospital outcomes.

Public health impact and economic evaluation of vitamin D-fortified dairy products for fracture prevention in France

The recommended intake of vitamin D-fortified dairy products can substantially decrease the burden of osteoporotic fractures and seems an economically beneficial strategy in the general French population aged over 60 years.

INTRODUCTION

This study aims to assess the public health and economic impact of vitamin D-fortified dairy products in the general French population aged over 60 years.

METHODS

We estimated the lifetime health impacts expressed in number of fractures prevented, life years gained, and quality-adjusted life years (QALY) gained of the recommended intake of dairy products in the general French population over 60 years for 1 year (2015). A validated microsimulation model was used to simulate three age cohorts for both women and men (60-69, 70-79, and >80 years). The incremental cost per QALY gained of vitamin D-fortified dairy products compared to the absence of appropriate intake was estimated in different populations, assuming the cost of two dairy products per day in base case.

RESULTS

The total lifetime number of fractures decreased by 64,932 for the recommended intake of dairy products in the general population over 60 years, of which 46,472 and 18,460 occurred in women and men, respectively. In particular, 15,087 and 4413 hip fractures could be prevented in women and men. Vitamin D-fortified dairy products also resulted in 32,569 QALYs and 29,169 life years gained. The cost per QALY gained of appropriate dairy intake was estimated at €58,244 and fall below a threshold of €30,000 per QALY gained in women over 70 years and in men over 80 years.

CONCLUSION

Vitamin D-fortified dairy products have the potential to substantially reduce the burden of osteoporotic fractures in France and seem an economically beneficial strategy, especially in the general population aged above 70 years.

Are health assets associated with improved outcomes for hospitalised older adults? A systematic review

OBJECTIVE

Health assets are protective factors that support health and wellbeing, rather than risk factors that are associated with disease. This concept was developed in the community setting. In hospitalised older adults, the dominant approach has been to identify risk factors, with little examination of health assets. The purpose of this systematic review was to determine whether, in hospitalised older people, individual health assets decrease the risk of post hospital mortality, functional decline, new need for residential care, readmission or longer length of stay.

METHODS

MEDLINE, EMBASE, CINAHL and PsycINFO were searched to identify studies examining outcomes for hospitalised older adults. Included studies examined at least one potential individual health asset, which was a psychosocial characteristic or health characteristic. Study quality was assessed, and findings are narratively described.

RESULTS

Nine prospective cohort and two retrospective cohort studies were identified. subjective, functional and biological health assets were identified. Health assets were associated with decreased risk of post-hospital mortality, functional decline, new need for residential care and readmission.

CONCLUSION

The complex interplay between health status and psychological and social factors is incompletely understood. Health assets are associated with improved outcomes for hospitalised older adults. The small number of studies suitable for inclusion indicates the need for further research in this area.

One-Year Outcomes in Caregivers of Critically Ill Patients

BACKGROUND

Few resources are available to support caregivers of patients who have survived critical illness; consequently, the caregivers' own health may suffer. We studied caregiver and patient characteristics to determine which characteristics were associated with caregivers' health outcomes during the first year after patient discharge from an intensive care unit (ICU).

METHODS

We prospectively enrolled 280 caregivers of patients who had received 7 or more days of mechanical ventilation in an ICU. Using hospital data and self-administered questionnaires, we collected information on caregiver and patient characteristics, including caregiver depressive symptoms, psychological well-being, health-related quality of life, sense of control over life, and effect of providing care on other activities. Assessments occurred 7 days and 3, 6, and 12 months after ICU discharge.

RESULTS

The caregivers' mean age was 53 years, 70% were women, and 61% were caring for a spouse. A large percentage of caregivers (67% initially and 43% at 1 year) reported high levels of depressive symptoms. Depressive symptoms decreased at least partially with time in 84% of the caregivers but did not in 16%. Variables that were significantly associated with worse mental health outcomes in caregivers were younger age, greater effect of patient care on other activities, less social support, less sense of control over life, and less personal growth. No patient variables were consistently associated with caregiver outcomes over time.

CONCLUSIONS

In this study, most caregivers of critically ill patients reported high levels of depressive symptoms, which commonly persisted up to 1 year and did not decrease in some caregivers. (Funded by the Canadian Institutes of Health Research and others; ClinicalTrials.gov number, NCT00896220.).

Evaluating Siebens Domain Management Model for inpatient rehabilitation to increase functional independence and discharge rate to home in geriatric patients

OBJECTIVE

To evaluate the Siebens Domain Management Model (SDMM) for geriatric inpatient rehabilitation (IR) to increase functional independence and dispositions to home.

DESIGN

Before and after study.

SETTING

IR facility.

PARTICIPANTS

During 2010 (preintervention), 429 patients aged ≥75 years who were on average admitted to IR 8.2 days postacute care, and during 2012 (postintervention), 524 patients aged ≥75 years who were on average admitted to IR 5.5 days postacute care. Case-mix group (CMG) comorbidity tier severity, preadmission living setting, and living support were similar in both groups.

INTERVENTION

The SDMM involving weekly adjustments of IR care focused on potential barriers to discharge home.

MAIN OUTCOME MEASURES

FIM efficiency, length of stay (LOS), and disposition rates to community/home, acute care, and long-term care (LTC) to compare pre-/postintervention facility data and comparison of facility to national CMG-adjusted data from the Uniform Data System for Medical Rehabilitation for both years (2010/2012).

RESULTS

Pre-/postintervention group admission FIM scores were similar (t=2.96, P<.003), but the preintervention group had on average 2.6 days greater LOS during IR and greater time to onset of IR (8.2 vs 5.5d) from acute care. Preintervention FIM efficiency was 2.1, whereas postintervention FIM efficiency was 2.76, a significant difference (t=4.1, P<.0001). There were significantly more discharges to the community in the postintervention group (74.4%) than the preintervention group (58.5%, χ(2)=26.2, P<.0001). There were significantly fewer patients discharged to LTC in the postintervention group (χ(2)=30.47, P<.0001). The preintervention group did not significantly differ from the 2010 national data, but the postintervention group significantly differed from the 2012 national data for both greater FIM efficiency (t=-5.5, P<.0001) and greater discharge to community (χ(2)=34, P<.0001). LOS decreased by 2.6 days in the postintervention group compared with the preintervention group, whereas LOS decreased by only 0.6 days nationally from 2010 to 2012, a significant difference with postintervention LOS lower than the national data (t=31.1, P<.0001).

CONCLUSIONS

Use of the SDMM during IR in geriatric patients is associated with increased functional independence and discharges to home/community and reduced institutionalization.

Risk factors and screening instruments to predict adverse outcomes for undifferentiated older emergency department patients: a systematic review and meta-analysis

OBJECTIVES

A significant proportion of geriatric patients experience suboptimal outcomes following episodes of emergency department (ED) care. Risk stratification screening instruments exist to distinguish vulnerable subsets, but their prognostic accuracy varies. This systematic review quantifies the prognostic accuracy of individual risk factors and ED-validated screening instruments to distinguish patients more or less likely to experience short-term adverse outcomes like unanticipated ED returns, hospital readmissions, functional decline, or death.

METHODS

A medical librarian and two emergency physicians conducted a medical literature search of PubMed, EMBASE, SCOPUS, CENTRAL, and ClinicalTrials.gov using numerous combinations of search terms, including emergency medical services, risk stratification, geriatric, and multiple related MeSH terms in hundreds of combinations. Two authors hand-searched relevant specialty society research abstracts. Two physicians independently reviewed all abstracts and used the revised Quality Assessment of Diagnostic Accuracy Studies instrument to assess individual study quality. When two or more qualitatively similar studies were identified, meta-analysis was conducted using Meta-DiSc software. Primary outcomes were sensitivity, specificity, positive likelihood ratio (LR+), and negative likelihood ratio (LR-) for predictors of adverse outcomes at 1 to 12 months after the ED encounters. A hypothetical test-treatment threshold analysis was constructed based on the meta-analytic summary estimate of prognostic accuracy for one outcome.

RESULTS

A total of 7,940 unique citations were identified yielding 34 studies for inclusion in this systematic review. Studies were significantly heterogeneous in terms of country, outcomes assessed, and the timing of post-ED outcome assessments. All studies occurred in ED settings and none used published clinical decision rule derivation methodology. Individual risk factors assessed included dementia, delirium, age, dependency, malnutrition, pressure sore risk, and self-rated health. None of these risk factors significantly increased the risk of adverse outcome (LR+ range = 0.78 to 2.84). The absence of dependency reduces the risk of 1-year mortality (LR- = 0.27) and nursing home placement (LR- = 0.27). Five constructs of frailty were evaluated, but none increased or decreased the risk of adverse outcome. Three instruments were evaluated in the meta-analysis: Identification of Seniors at Risk, Triage Risk Screening Tool, and Variables Indicative of Placement Risk. None of these instruments significantly increased (LR+ range for various outcomes = 0.98 to 1.40) or decreased (LR- range = 0.53 to 1.11) the risk of adverse outcomes. The test threshold for 3-month functional decline based on the most accurate instrument was 42%, and the treatment threshold was 61%.

CONCLUSIONS

Risk stratification of geriatric adults following ED care is limited by the lack of pragmatic, accurate, and reliable instruments. Although absence of dependency reduces the risk of 1-year mortality, no individual risk factor, frailty construct, or risk assessment instrument accurately predicts risk of adverse outcomes in older ED patients. Existing instruments designed to risk stratify older ED patients do not accurately distinguish high- or low-risk subsets. Clinicians, educators, and policy-makers should not use these instruments as valid predictors of post-ED adverse outcomes. Future research to derive and validate feasible ED instruments to distinguish vulnerable elders should employ published decision instrument methods and examine the contributions of alternative variables, such as health literacy and dementia, which often remain clinically occult.

Evaluating use of the Siebens Domain Management Model during inpatient rehabilitation to increase functional independence and discharge rate to home in stroke patients

OBJECTIVE

To evaluate use of the Siebens Domain Management Model (SDMM) during stroke inpatient rehabilitation (IR) to increase functional independence and rate of discharge to home.

DESIGN

Before and after study.

SETTING

IR facility.

PARTICIPANTS

Before the intervention: 154 patients with ischemic/hemorrhagic strokes who were admitted to an IR facility in 2010; on average, they were admitted 9.1 days after receiving acute care. After the intervention: 151 patients with ischemic/hemorrhagic strokes who were admitted to an IR facility in 2012; on average they were admitted 7.3 days after receiving acute care. The comorbidity tier severity and prestroke living setting and living support appeared to be similar in both the preintervention and postintervention groups.

INTERVENTION

Use of the SDMM involving weekly adjustments of IR care focused on potential barriers to discharge home including medical/surgical issues, cognitive/emotional coping issues, physical function, and living environment/community re-entry needs.

MAIN OUTCOME MEASURES

Use of Functional Independence Measure (FIM) score change during IR length of stay (LOS; FIM-LOS efficiency) and rates of discharge to community/home, acute care, and long-term care (LTC) to compare 2010/preintervention data with postintervention data from 2012, along with comparison of facility data to national aggregate data from the Uniform Data System for Medical Rehabilitation (UDSMR) for both years.

RESULTS

Preintervention 2010 FIM-LOS efficiency was 1.44 compared with a 2012 postintervention FIM-LOS efficiency of 2.24, which was significant (t = 4.3; P < .0001). Comparison of the UDSMR 2012 national FIM-LOS efficiency score (1.72) to the 2012 postintervention score of 2.24 reached significance (t = 2.6; P < .01). In addition, a significant difference was found between groups for discharge location: In the preintervention group, 57.8% were discharged to home/community, 14.9% to LTC, and 27.3% back to acute care compared with the postintervention group, in which 81.2% were discharged to home/community, 9.4% to LTC, and 9.4% back to acute care (χ(2) = 8.98; P < .001). Also significant was comparison between the 2012 postintervention group and the 2012 national UDSMR data for the same 3 discharge locations (χ(2) = 3.94; P < .05). Comparison of 2010 to 2012 facility data then shows a 23.4% increase in discharge to the community compared with an increase of 5.8% for the UDSMR 2010 to 2012 data, representing a community discharge rate that is 4 times greater for the 2012 facility postintervention group (χ(2) = 83.596; P < .0001).

CONCLUSIONS

Use of the SDMM during stroke IR may convey improvement in functional independence and is associated with an increased discharge rate to home/community and a reduction in institutionalization and acute-care transfers.

Can nurses tell the future? Creation of a model predictive of 30-day readmissions

The estimated cost for hospital readmissions in 2011 was more than $41 billion, but the costs to patients in terms of quality of life are immeasurable. The purpose of this study was to determine if there are variables available to nurses at the time of the patient's admission that could be predictive of a 30-day hospital readmission. Logistic regression was used in a stepwise approach to determine the variable combinations most predictive for 30-day readmission. Thirty-two variables were found to be significantly predictive of 30-day readmissions from the more than 1400 examined.

Nursing home admission during the first year after hospitalization - the contribution of cognitive impairment

OBJECTIVE

The importance of cognitive and physical functioning for nursing home admission among medically hospitalized older patients is rarely studied in a one-year follow-up perspective. This study aims to explore the association between patient characteristics and nursing home admission within one year after hospitalization in persons 65 years or more.

DESIGN

A one-year longitudinal study.

METHODS

We included 463 (234 women) persons aged 65 years or more from internal medical wards in a rural area of Norway. Cognitive function was assessed using the Mini Mental State Examination; physical and instrumental functional status was assessed using the physical self-maintenance scale and instrumental activities of daily living scale of Lawton and Brody. Comorbidity was measured with the Charlson index. Admission to nursing home within one year (yes versus no) was analyzed using logistic regression analysis and Cox proportional hazard regression analysis.

RESULTS

The mean age of the sample was 80.5 (SD 7.4) years, mean Mini Mental State Examination score was 24.1 (SD 3.8) (maximum score is 30). In adjusted analysis participants with cognitive impairment (a Mini Mental State Examination score <25) or impaired physical functioning at baseline had higher risk of admission to nursing home within one year (OR 3.0, 95%CI 1.5-6.2 and OR 3.5, 95%CI 1.8-9.6, respectively). The time before admission was also associated with cognitive impairment and impaired physical functioning in the adjusted analysis (HR 2.6 95%CI 1.4-4.8 and HR 3.7, 95%CI 1.5-8.9, respectively).

CONCLUSION

Impaired cognitive and physical functioning increased the risk for nursing home admission within one year after hospitalization. However, putative regressors, such as education and social network were not included in the analysis.

A follow-up intervention in severely demented patients after discharge from a special Alzheimer acute care unit: impact on early emergency room re-hospitalization rate

BACKGROUND

Emergency room (ER) re-hospitalizations are prevalent in severe Alzheimer's disease affected older patients.

DESIGN

Quasi-experimental before and after study.

SETTING

Discharge of severely demented patients from a Special Alzheimer Acute Care Unit.

PARTICIPANTS

A total of 390 patients hospitalized in the unit from 2007 through 2009, with at least one of the following characteristics: severe disruptive behavioral and psychological symptoms of dementia (BPSD) (agitation, aggressiveness, and psychotic symptoms), change of living arrangement related to BPSD, exhaustion of the principal caregiver, and discharge of a subject with anosognosia living alone in the community.

INTERVENTION

The intervention consisted of an individualized care plan, targeting the problems observed during the hospital stay, implemented by the means of regular telephone contacts (in the first week after discharge, before the end of the first month, and then at 3 and 6 months) between a geriatric team and the patient's caregiver. Information was gathered on functional decline, BPSD, change of living arrangement and treatment. The calls were followed by a telephone intervention providing advice, support, and information to the caregiver. When required, these calls were followed by a consultation with a physician or psychologist, or by a consultation in the patient's home.

MEASUREMENTS

The primary outcome measure was the ER re-hospitalization rate, defined as occurring within 31 days of discharge.

RESULTS

The early ER re-hospitalization rate was 8.39% in 2007 versus 8.02% in 2008 (p = 0.818) and 7.47% in 2009 (p = 0.563). Vocal disruptive behavior are more prevalent in re-hospitalized patients (9.64% versus 3.97%, p = 0.05) than in non re-hospitalized patients.

CONCLUSION

We found a nonsignificant decrease of early ER re-hospitalization rate at 1 month after discharge. Interventions addressing severe dementia affected patients with BPSD are needed, as this is a major issue in the organization of health care systems.

Rapid cognitive decline, one-year institutional admission and one-year mortality: analysis of the ability to predict and inter-tool agreement of four validated clinical frailty indexes in the SAFEs cohort

OBJECTIVES

To evaluate the predictive ability of four clinical frailty indexes as regards one-year rapid cognitive decline (RCD - defined as the loss of at least 3 points on the MMSE score), and one-year institutional admission (IA) and mortality respectively; and to measure their agreement for identifying groups at risk of these severe outcomes.

DESIGN

One-year follow-up and multicentre study of old patients participating in the SAFEs cohort study.

SETTING

Nine university hospitals in France.

PARTICIPANTS

1,306 patients aged 75 or older (mean age 85±6 years; 65% female) hospitalized in medical divisions through an Emergency department.

MEASUREMENTS

Four frailty indexes (Winograd; Rockwood; Donini; and Schoevaerdts) reflecting the multidimensionality of the frailty concept, using an ordinal scoring system able to discriminate different grades of frailty, and constructed based on the accumulation of identified deficits after comprehensive geriatric assessment conducted during the first week of hospital stay, were used to categorize participants into three different grades of frailty: G1 - not frail; G2 - moderately frail; and G3 - severely frail. Comparisons between groups were performed using Fisher's exact test. Agreement between indexes was evaluated using Cohen's Kappa coefficient.

RESULTS

All patients were classified as frail by at least one of the four indexes. The Winograd and Rockwood indexes mainly classified subjects as G2 (85% and 96%), and the Donini and Schoevaerdts indexes mainly as G3 (71% and 67%). Among the SAFEs cohort population, 250, 1047 and 1,306 subjects were eligible for analyses of predictability for RCD, 1-year IA and 1-year mortality respectively. At 1 year, 84 subjects (34%) experienced RCD, 377 (36%) were admitted into an institutional setting, and 445 (34%) had died. With the Rockwood index, all subjects who experienced RCD were classified in G2; and in G2 and G3 when the Donini and Schoevaerdts indexes were used. No significant difference was found between frailty grade and RCD, whereas frailty grade was significantly associated with an increased risk of IA and death, whatever the frailty index considered. Agreement between the different indexes of frailty was poor with Kappa coefficients ranging from -0.02 to 0.15.

CONCLUSION

These findings confirm the poor clinimetric properties of these current indexes to measure frailty, underlining the fact that further work is needed to develop a better and more widely-accepted definition of frailty and therefore a better understanding of its pathophysiology.

Reducing "iatrogenic disability" in the hospitalized frail elderly

BACKGROUND

Hospitalization is the first cause of functional decline in the elderly: 30 to 60% of elderly patients lose some independence in basic activities of daily living (ADL) during a stay in hospital. This loss of independence results from the acute condition that led to admission, but is also related to the mode of management.

OBJECTIVE

This paper is a review of the literature on functional decline in elderly hospitalized patients. It is the first stage in a project aiming to prevent dependence that is induced during the course of care.

METHODS

During a 2-day workshop in Monaco, a task force of 20 international experts discussed and defined the concept of "iatrogenic disability".

RESULTS

1- "Iatrogenic disability" was defined by the task force as the avoidable dependence which often occurs during the course of care. It involves three components that interact and have a cumulative effect: a) the patient's pre-existing frailty, b) the severity of the disorder that led to the patient's admission, and lastly c) the hospital structure and the process of care. 2- The prevention of "iatrogenic disability" involves successive stages. - becoming aware that hospitalization may induce dependence. Epidemiological studies have identified at-risk populations by the use of composite scores (HARP, ISAR, SHERPA, COMPRI, etc). - considering that functional decline is not a fatality. Quality references have already been defined. Interventions to prevent dependence in targeted populations have been set up: simple geriatric consultation teams, single-factor interventions (aimed for example at mobility, delirium, iatrogenic disorders) or multidomain interventions (such as GEM and ACE units, HELP, Fast Track, NICHE). These interventions are essentially centered on the patient's frailty and have limited results, as they take little account of the way the institution functions, which is not aimed at prevention of functional decline. The process of care reveals shortcomings: lack of geriatric knowledge, inadequate evaluation and management of functional status. The group suggests that interventions must not only identify at-risk patients so that they may benefit from specialized management, but they must also target the hospital structure and the process of care. This requires a graded "quality approach" and rethinking of the organization of the hospital around the elderly person.
