Does cognitive impairment affect rehabilitation outcome?

Post-Acute Care Rehabilitation for Persons Living With Dementia: A Systematic Review

OBJECTIVES

To identify the results of post-acute care (PAC) rehabilitation for persons living with dementia (PLWD).

DESIGN

Systematic review of published literature without date restrictions through April 2023.

SETTING AND PARTICIPANTS

PLWD undergoing rehabilitation in PAC facilities after an acute care hospitalization.

METHODS

A systematic search was carried out in PubMed, Scopus, Google Scholar, Embase, Medline, PsycINFO, CINAHL, Cochrane Library, and Web of Science. Included studies were peer-reviewed, available in English, and focused on PLWD admitted to rehabilitation facilities following hospitalization in the US and international settings. Studies on long-term care and acute inpatient rehabilitation units were excluded. Two reviewers independently screened articles and conducted a quality appraisal of selected studies. A narrative synthesis approach was used for analysis of results with rehabilitation themes encompassing "outcomes" and "experiences."

RESULTS

Forty-one articles met inclusion criteria, with a heterogeneity of study designs including observational (n = 33), randomized clinical trials (n = 3), and qualitative studies (n = 5). Narrative synthesis demonstrated that PAC rehabilitation for PLWD contained themes of "outcomes," including health service utilization and physical and cognitive function, providing evidence for a lower likelihood to return home and achieving less functional improvement compared to individuals without cognitive impairment. The second theme, "experiences," included health care transitions, knowledge and education, goal alignment, and care models. Findings detailed poor communication around care transitions, lack of dementia knowledge among health care workers, goal alignment strategies, and innovative rehabilitation models specific for PLWD.

CONCLUSIONS AND IMPLICATIONS

Overall, this systematic review covers a breadth of literature across time and international settings on PAC rehabilitation for PLWD. The findings highlight the importance of rehabilitation models specific for dementia care, with a need for personalized approaches around care transitions, goal setting, and increased dementia education. Addressing these aspects of rehabilitative care for PLWD may enhance the delivery of PAC and improve health care outcomes and experiences.

Impact of dementia and socioeconomic disadvantage on days at home after traumatic brain injury among older Medicare beneficiaries: A cohort study

INTRODUCTION

Time spent at home may aid in understanding recovery following traumatic brain injury (TBI) among older adults, including those with Alzheimer's disease and related dementias (ADRD). We examined the impact of ADRD on recovery following TBI and determined whether socioeconomic disadvantages moderated the impact of ADRD.

METHODS

We analyzed Medicare beneficiaries aged ≥65 years diagnosed with TBI in 2010-2018. Home time was calculated by subtracting days spent in a care environment or deceased from total follow-up, and dual eligibility for Medicaid was a proxy for socioeconomic disadvantage.

RESULTS

A total of 2463 of 20,350 participants (12.1%) had both a diagnosis of ADRD and were Medicaid dual-eligible. Beneficiaries with ADRD and Medicaid spent markedly fewer days at home following TBI compared to beneficiaries without either condition (rate ratio 0.66; 95% confidence interval [CI] 0.64, 0.69).

DISCUSSION

TBI resulted in a significant loss of home time over the year following injury among older adults with ADRD, particularly for those who were economically vulnerable.

HIGHLIGHTS

Remaining at home after serious injuries such as fall-related traumatic brain injury (TBI) is an important goal for older adults. No prior research has evaluated how ADRD impacts time spent at home after TBI. Older TBI survivors with ADRD may be especially vulnerable to loss of home time if socioeconomically disadvantaged. We assessed the impact of ADRD and poverty on a novel DAH measure after TBI. ADRD-related disparities in DAH were significantly magnified among those living with socioeconomic disadvantage, suggesting a need for more tailored care approaches.

Associations Between Patient Characteristics and Unplanned or Delayed Discharges From Geriatric Rehabilitation: A Retrospective Chart Review

ABSTRACT

Returning home is considered an indicator of successful rehabilitation for community-dwelling older adults. However, the factors associated with unplanned discharge remain uncertain. This retrospective chart review included patients 65 yrs and older admitted to a geriatric rehabilitation unit from medical and surgical wards in an academic hospital. Patient characteristics and outcomes were abstracted from the electronic medical record. The primary outcome was unplanned discharge destination defined as anything other than return to patients' preexisting residence. The associations between patient variables and unplanned discharge destination were analyzed using Pearson χ 2 and univariate logistic regression. Of the 251 charts screened, 25 patients (10.0%) had an unplanned discharge destination, and 74 of the remaining 226 (32.7%) experienced a delayed discharge (beyond 20 days). Requiring assistance for activities of daily living (odds ratio [OR], 2.80; 95% confidence interval [CI], 1.17-7.47), a diagnosis of chronic obstructive pulmonary disease (OR, 4.04; 95% CI, 1.63-9.71), and lower serum albumin level (OR, 1.67; 95% CI, 1.06-2.72) were associated with unplanned discharge. Variables commonly associated with worse outcomes such as age, cognitive scores, delirium, and number of comorbidities were not barriers to returning home and should therefore not be used on their own to limit access to geriatric rehabilitation.

Short-Term, Community-Based, Slow-Stream Rehabilitation Program for Older Adults Transitioning from Hospital to Home: A Mixed Methods Program Evaluation

Introduction

Shortened hospital stays have shifted the burden of care for older adults to community, informal (ie, family, caregiver) and formal post-acute care and services, highlighting the need for effective post-hospital stay services and programs. As there is a dearth of information related to community-based, slow-stream rehabilitation program models for older adults transitioning from hospital to home in the Canadian context, the paper describes a mixed methods evaluation of such a program.

Materials and Methods

A mixed methods program evaluation, with process- and outcome-related elements, included 1) review and analysis of program documents; 2) observations to examine fidelity. Observation data were coded and summarized using descriptive statistics. Coded information and data were compared to document review data; 3) quantitative assessment of pre-post changes in physical, social, and psychological outcome measure and instrument scores using descriptive statistics, paired t-tests and confidence intervals (p = 0.05); and 4) exploration of acceptability through interviews and focus groups with 41 of the older adult participants and 17 family caregivers. Thematic analysis was used to examine focus group and interview transcripts.

Results

Observational data indicated alignment with the program document information overall. Statistically and clinically significant positive trends in improvement for physical outcome measure scores were observed (6-minute Walk Test, Life Space Assessment, Short Physical Performance Battery, Rapid Assessment of Physical Activity). Participants and family caregivers identified several positives and benefits of the program, ie, improvement in physical, social and mental well-being, decreased caregiver burden; and areas for improvement ie, need for more information about the program prior to enrollment and individualization, several of which aligned with the observation and quantitative data.

Discussion/Conclusion

This mixed methods program evaluation provided a detailed description of a community-based, slow-stream rehabilitation program for older adults who are transitioning to home post-hospital stay and its participants. Evidence of program fidelity, acceptability, and positive trends in improvement in physical outcome measure scores were found. Information about program strengths and areas for improvement can be used by stakeholders to inform program refinement and enhancement.

Multidisciplinary inpatient rehabilitation for older adults with COVID-19: a systematic review and meta-analysis of clinical and process outcomes

BACKGROUND

Older adults are at increased risk for disease severity and poorer prognosis following COVID-19 infection. The aim of this systematic review and meta-analysis is to explore the impact of multidisciplinary rehabilitation in the acute or post-acute hospital setting for older adults with COVID-19.

METHODS

The Cochrane library, EMBASE, Cinahl and Medline (via EBSCO), PubMed, and Web of Science were systematically searched in June 2022 and a repeat search was completed in March 2023. Screening, data extraction and quality appraisal were conducted independently by two reviewers. Studies reporting outcomes for older adults following multidisciplinary rehabilitation (provided by two or more Health and Social Care Professionals) were included. Both observational and experimental study designs were included. The primary outcome was functional ability. Secondary outcomes included discharge disposition, acute hospital and rehabilitation unit length of stay, mortality, primary and secondary healthcare utilisation, and long-term effects of COVID-19.

RESULTS

Twelve studies met the inclusion criteria, comprising a total of 570 older adults. Where reported, older adults stayed in the acute hospital for a mean of 18 days (95%CI, 13.35- 23.13 days) and in rehabilitation units for 19 days (95%CI, 15.88-21.79 days). There was a significant improvement in functional ability among older adults with COVID-19 who received multidisciplinary rehabilitation (REM, SMD = 1.46, 95% CI 0.94 to 1.98). The proportion of older adults who were discharged directly home following rehabilitation ranged from 62 to 97%. Two studies reported a 2% inpatient mortality rate of older persons during rehabilitative care. No study followed up patients after the point of discharge and no study reported on long term effects of COVID-19.

CONCLUSIONS

Multidisciplinary rehabilitation may result in improved functional outcomes on discharge from rehabilitation units/centres for older adults with COVID-19. Findings also highlight the need for further research into the long-term effect of rehabilitation for older adults following COVID-19. Future research should comprehensively describe multidisciplinary rehabilitation in terms of disciplines involved and the intervention provided.

Tele-Medicine Based and Self-Administered Interactive Exercise Program (Tele-Exergame) to Improve Cognition in Older Adults with Mild Cognitive Impairment or Dementia: A Feasibility, Acceptability, and Proof-of-Concept Study

Improved life expectancy is increasing the number of older adults who suffer from motor-cognitive decline. Unfortunately, conventional balance exercise programs are not tailored to patients with cognitive impairments, and exercise adherence is often poor due to unsupervised settings. This study describes the acceptability and feasibility of a sensor-based in-home interactive exercise system, called tele-Exergame, used by older adults with mild cognitive impairment (MCI) or dementia. Our tele-Exergame is specifically designed to improve balance and cognition during distractive conditioning while a telemedicine interface remotely supervises the exercise, and its exercises are gamified balance tasks with explicit augmented visual feedback. Fourteen adults with MCI or dementia (Age = 68.1 ± 5.4 years, 12 females) participated and completed exergame twice weekly for six weeks at their homes. Before and after 6 weeks, participants' acceptance was assessed by Technology Acceptance Model (TAM) questionnaire, and participants' cognition and anxiety level were evaluated by the Montreal Cognitive Assessment (MoCA) and Beck Anxiety Inventory (BAI), respectively. Results support acceptability, perceived benefits, and positive attitudes toward the use of the system. The findings of this study support the feasibility, acceptability, and potential benefit of tele-Exergame to preserve cognitive function among older adults with MCI and dementia.

A non-randomised feasibility study of the Rehabilitation Potential Assessment Tool (RePAT) in frail older people in the acute healthcare setting

BACKGROUND

Rehabilitation potential involves predicting who will benefit from rehabilitation. Decisions about rehabilitation potential must take into account personal, clinical and contextual factors, a process which is complicated in the presence of acute ill-health and frailty. This study aimed to evaluate the feasibility and acceptability of the Rehabilitation Potential Assessment Tool (RePAT) - a 15 item holistic, person-centred assessment tool and training package - in the acute hospital setting.

METHODS

A non-randomised feasibility study with nested semi-structured interviews explored whether RePAT was feasible and acceptable. Feasibility was tested by recruiting physiotherapy and occupational therapy participants delivering the RePAT intervention to patients alongside usual clinical care. Acceptability was tested by conducting semi-structured interviews with staff, patient and carer participants. Staff and patient characteristics were analysed using descriptive statistics. Interview data were analysed thematically. Fidelity of completed RePAT items was assessed against a priori criteria on how closely they matched tool guidance by two researchers. Mean values of the two scores were calculated. RePAT content was analysed and supported with verbatim quotes.

RESULTS

Six staff participants were recruited and trained. They assessed 26 patient participants using RePAT. Mean (SD) patient age was 86.16 (±6.39) years. 32% were vulnerable or mildly frail, 42% moderately frail and 26% severely or very severely frail using the Clinical Frailty Scale. Mean (SD) time to complete RePAT was 32.7 (±9.6) minutes. RePAT fidelity was good where 13 out of 15 items achieved a priori fidelity. RePAT was acceptable and tolerated by staff and patients. Staff participants reported RePAT enabled them to consider rehabilitation decisions in a more structured and consistent way. Patients and carer participants, although unable to comment directly on RePAT, reported being satisfied with their rehabilitation assessments which were found to embrace a person-centred approach.

CONCLUSIONS

RePAT was found to be acceptable and feasible by staff, carers and patients. It allowed clinicians to make explicit their reasoning behind rehabilitation assessments and encouraged them to become more cognisant of factors which affected their clinical decision-making.

Characteristics and Outcome Determinants of Hospitalized Older Patients with Cognitive Dysfunction

Cognitive dysfunction commonly occurs among older patients during admission and is associated with adverse prognosis. This study evaluated clinical characteristics and outcome determinants in hospitalized older patients with cognitive disorders. The main outcomes were length of stay, readmission within 30 days, Barthel index (BI) score at discharge, BI score change (discharge BI score minus BI score), and proportion of positive BI score change to indicate change of activities of daily living (ADL) change during hospitalization. A total of 642 inpatients with a mean age of 79.47 years (76–103 years) were categorized into three groups according to the medical history of dementia, and Mini-Mental State Examination (MMSE) scores at admission. Among them, 74 had dementia diagnosis (DD), 310 had cognitive impairment (CI), and 258 had normal MMSE scores. Patients with DD and CI generally had a higher risk of many geriatric syndromes, such as multimorbidities, polypharmacy, delirium, incontinence, visual and auditory impairment, fall history, physical frailty. They had less BI score, BI score change, and proportion of positive BI score change ADL at discharge. (DD 70.0%, CI 79.0%), suggesting less ADL change during hospitalization compared with those with normal MMSE scores (92.9%; p < 0.001). Using multiple regression analysis, we found that among patients with DD and CI, age (p = 0.008) and walking speed (p = 0.023) were predictors of discharge BI score. In addition, age (p = 0.047) and education level were associated with dichotomized BI score change (positive vs. non-positive) during hospitalization. Furthermore, the number and severity of comorbidities predicted LOS (p < 0.001) and readmission (p = 0.001) in patients with cognitive disorders. It is suggested that appropriate strategies are required to improve clinical outcomes in these patients.

Rehabilitation potential in older people living with frailty: a systematic mapping review

Background

Following periods of acute ill-health and injury, older people are frequently assessed and provided with rehabilitation services. Healthcare practitioners are required to make nuanced decisions about which patients are likely to benefit from and respond to rehabilitation. The clinical currency in which these decisions are transacted is through the term “rehabilitation potential”. The aim of this study was to explore information about rehabilitation potential in older people to inform the development of an evidence-based assessment tool.

Methods

A systematic mapping review was completed to describe the extent of research and the concepts underpinning rehabilitation potential. We searched Medline, CINHAL, EMBASE, AMED, PsycINFO, PEDro, Cochrane Library, Web of Science, ProQuest, Trip and EThOS from inception to December 2020. We included studies which focused on rehabilitation potential and/or assessing for rehabilitation interventions for older people with comorbidities in the hospital and community setting. Reviewer pairs independently screened articles and extracted data against the inclusion criteria. A descriptive narrative approach to analysis was taken.

Results

13,484 papers were identified and 49 included in the review. Rehabilitation potential was found to encompass two different but interrelated concepts of prognostication and outcome measurement. 1. Rehabilitation potential for prognostication involved the prediction of what could be achieved in programmes of rehabilitation. 2. Rehabilitation potential as an outcome measure retrospectively considered what had been achieved as a result of rehabilitation interventions. Assessments of rehabilitation potential included key domains which were largely assessed by members of the multi-disciplinary team at single time points. Limited evidence was identified which specifically considered rehabilitation potential amongst older people living with frailty.

Conclusions

Current approaches to rehabilitation potential provide a snapshot of an individual’s abilities and conditions which fail to capture the dynamic nature and fluctuations associated with frailty and rehabilitation. New approaches to measures and abilities over time are required which allow for the prognostication of outcomes and potential benefits of rehabilitation interventions for older people living with frailty.

The relationship between common cognitive screening tests (Standardised Mini-Mental State Examination and Rowland Universal Dementia Assessment Scale) and the Cognitive Functional Independence Measure

OBJECTIVES

To assess whether the Cognitive Functional Independence Measure (Cog-FIM) is correlated with the Standardised Mini-Mental State Examination (SMMSE) and Rowland Universal Dementia Assessment Scale (RUDAS) and whether there is agreement between the Cog-FIM and these two tests.

METHODS

Functional Independence Measure assessments were undertaken on 98 subacute patients. Forty-eight (48) patients were administered the SMMSE, and 50 were administered the RUDAS. Agreement was examined using the Bland-Altman plot.

RESULTS

Correlation was observed between the Cog-FIM and both the SMMSE and the RUDAS. The Bland-Altman analysis demonstrated agreement between the Cog-FIM and RUDAS, but not the Cog-FIM and SMMSE. The limits of agreement between the Cog-FIM and RUDAS were -13 to 13.

CONCLUSION

The Cog-FIM is correlated with the RUDAS, but the agreement is unclear. Despite agreement of the means, the limits of agreement are large, which may suggest a clinically meaningful difference. The study should be repeated with a larger sample size.

Influence of Cognitive Impairment on Rehabilitation Received and Its Mediating Effect on Functional Recovery

BACKGROUND

Cognitive impairment (CI) has been reported to negatively impact rehabilitation outcomes. Knowledge about differences in rehabilitation received in dependence of CI as a potential mediating factor is limited.

OBJECTIVE

To analyze whether CI affects amount and frequency of rehabilitation received and if associations between CI and rehabilitation outcome are mediated by the provided amount of therapy.

METHODS

Observational cohort study in ward-based geriatric rehabilitation consecutively including 373 patients (mean age 82.0±6.69 years, mean MMSE 23.66±5.31). Outcome measures were amount, frequency, and type of multi-professional therapy sessions and rehabilitation outcome assessed with the Barthel Index (BI). Cognitive status was measured with the Mini-Mental-State Examination (MMSE) classifying three patient subgroups according to cognitive status.

RESULTS

Patients with more severe CI received least total therapy hours (TTH) (MMSE < 17, 13.67±6.58 versus MMSE 17-26, 16.12±7.19 and MMSE > 26, 17.79±8.88 h, p = 0.014) and were less often included in occupational therapy (MMSE < 17, 48.9%versus MMSE 17-26, 65.5%and MMSE > 26, 71.4%, p = 0.019) and group-based physiotherapy (MMSE < 17, 73.3%versus MMSE 17-26, 88.5%and MMSE > 26, 81.2%, p = 0.027). Regression models showed that CI negatively impacted TTH (β= 0.24, p = 0.003) and rehabilitation outcome (β= 0.41, p = 0.008). In the mediation model, TTH accounted for 23.18%(p < 0.001) of the relationship between CI and rehabilitation outcome.

CONCLUSION

Cognitive impairment negatively impacted rehabilitation received. The lower TTH partly mediated the negative association between CI and rehabilitation outcome. Future research should identify specific barriers to therapy provision and optimal length, intensity, and dosage of rehabilitation programs to optimize rehabilitation outcomes in CI.

Exploring rehabilitation potential in older people living with frailty: a qualitative focus group study

BACKGROUND

Rehabilitation interventions are frequently cited as key in supporting frail older people's recovery following periods of decompensation and acute ill-health. Clinicians are required to make decisions about a patient's potential to respond to rehabilitation. 'Rehabilitation potential' decisions can determine access to services. In acute settings clinicians have limited time to assess and work with patients, families and carers. The complexities of ageing, recovery, rehabilitation and frailty may not be fully appreciated. This study aimed to explore multiple perspectives of the concept of rehabilitation potential and how it is assessed in older people living with frailty in the acute healthcare setting.

METHODS

Five focus groups with a purposive sample of 28 participants which included clinicians and members of the public were conducted. Analysis comprised a thematic approach using the Framework method.

RESULTS

Rehabilitation potential was found to encapsulate a complex decision-making process where clinicians judged an individual's ability to benefit from and participate in targeted rehabilitation. They asked, "Will it work?", "Is it wanted?" and "Is it available?" In order to predict who would benefit from rehabilitation interventions, clinicians assessed a range of holistic clinical and non-clinical factors. An iterative approach to assessment delivered by a multi-disciplinary team, centred around patient and carer needs and wants was needed to accommodate complexity. Participants believed that everyone had some form of potential but this was dependent on availability of rehabilitation resources and conceptualisations of frailty and rehabilitation. Tensions between iterative approaches to rehabilitation potential assessment and the realities of rapid decision making in the acute hospital setting were found.

CONCLUSION

Rehabilitation potential decisions involve a complex process of multidisciplinary decision-making and prognostication on the likely outcome and benefit from rehabilitation programmes. These findings lay the foundation for developing structured approaches to rehabilitation potential decision making tools and guidance.

Rehabilitation of persons with dementia: using technology to improve participation

OBJECTIVES

The current study examined how a technology system, "It's Never 2 Late" (iN2L), may help augment traditional rehabilitation strategies for older adults with dementia by improving engagement in therapy sessions and achieving better functional outcomes.

METHOD

The study used a two group quasi-experimental design. Older adults with dementia (N = 96) were recruited from two rehabilitation departments housed within residential care communities. Participants received daily occupational and physical therapy sessions using treatment as usual (TAU) at one site (n = 49) or treatment with iN2L (n = 47) at the other site. A goal attainment approach was used to assess functional outcomes. It was hypothesized that patients whose therapists used iN2L in treatment will show greater attainment of therapy goals and greater engagement during OT and PT sessions than patients receiving TAU. It was also hypothesized that levels and improvement in engagement will mediate the association of treatment type (iN2L or TAU) with greater goal attainment.

RESULTS

Participants in the iN2L treatment had significantly higher goal attainment than TAU, significantly higher levels of engagement at baseline, and significantly steeper increases in engagement over the course of therapy. The effects of treatment on goal attainment was significantly mediated by increases in engagement.

CONCLUSION

Findings suggest that iN2L technology has the potential to increase treatment engagement and enhance rehabilitation outcomes among older adults with dementia.

Factors associated with improved walking in older people during hospital rehabilitation: secondary analysis of a randomized controlled trial

Background

Older people are often admitted for rehabilitation to improve walking, yet not everyone improves. The aim of this study was to determine key factors associated with a positive response to hospital-based rehabilitation in older people.

Methods

This was a secondary data analysis from a multisite randomized controlled trial. Older people (n= 198, median age 80.9 years, IQR 76.6- 87.2) who were admitted to geriatric rehabilitation wards with a goal to improve walking were recruited. Participants were randomized to receive additional daily physical therapy focused on mobility (n = 99), or additional social activities (n = 99). Self-selected gait speed was measured on admission and discharge. Four participants withdrew. People who changed gait speed ≥0.1 m/s were classified as ‘responders’ (n = 130); those that changed <0.1m/s were classified as ‘non-responders’ (n = 64). Multivariable logistic regression explored the association of six pre-selected participant factors (age, baseline ambulation status, frailty, co-morbidities, cognition, depression) and two therapy factors (daily supervised upright activity time, rehabilitation days) and response.

Results

Responding to rehabilitation was associated with the number of days in rehabilitation (OR 1.04; 95% CI 1.00 to 1.08; p = .039) and higher Mini Mental State Examination scores (OR 1.07, 95% CI 1.00 – 1.14; p = .048). No other factors were found to have association with responding to rehabilitation.

Conclusion

In older people with complex health problems or multi-morbidities, better cognition and a longer stay in rehabilitation were associated with a positive improvement in walking speed. Further research to explore who best responds to hospital-based rehabilitation and what interventions improve rehabilitation outcomes is warranted.

Post-stroke cognitive impairments and responsiveness to motor rehabilitation: A review

PURPOSE OF REVIEW

a)This review discusses the prevalence of cognitive deficits following stroke and their impact on responsiveness to therapeutic intervention within a motor learning context.

RECENT FINDINGS

b)Clinical and experimental studies have established that post-stroke cognitive and motor deficits may impede ambulation, augment fall risk, and influence the efficacy of interventions. Recent research suggests the presence of cognitive deficits may play a larger role in motor recovery than previously understood.

SUMMARY

c)Considering that cognitive impairments affect motor relearning, post-stroke motor rehabilitation therapies may benefit from formal neuropsychological testing. For example, early work suggests that in neurotypical adults, cognitive function may be predictive of responsiveness to motor rehabilitation and cognitive training may improve mobility. This sets the stage for investigations probing these topics in people post-stroke. Moreover, the neural basis for and extent to which these cognitive impairments influence functional outcome remains largely unexplored and require additional investigation.

[Preoperative cognitive function in very old patients : Influence on the complication rate and length of hospitalization]

BACKGROUND

Gastrointestinal cancer is a frequent diagnosis in older patients. A curative resection, possibly in combination with radiotherapy and/or chemotherapy, is the standard therapy. The advanced age of the patients with an increasing number of comorbidities and often the presence of cognitive impairment represents a high risk for perioperative complications and a longer stay in hospital. The challenge in the clinical routine is to recognize a cognitive impairment in older patients and to prepare these patients for the operative intervention in the best possible way.

OBJECTIVE

This retrospective analysis was carried out to find out whether preoperative cognitive impairment is a prognostic factor for the postoperative outcome.

METHODS

In patients over the age of 75 years who were prepared for abdominal surgery of gastrointestinal cancer in the preoperative consultation, the mini mental state examination (MMSE) and the clock test were carried out. The results of the tests were retrospectively compared with the complication rate and the duration of hospital stay.

RESULTS

Low MMSE values were significantly associated with the complication rate and the development of a severe complication (Clavien-Dindo grade ≥ 3a). A cut-off value of 24 points in the MMSE was predictive for the development of complications and a longer hospital stay. The age of the patients was not associated with the MMSE.

CONCLUSION

Cognitive impairment is an important prognostic factor for the development of perioperative complications and the duration of the hospital stay in patients undergoing extensive abdominal surgery for gastrointestinal cancer. Therefore, a preoperative assessment, for example with the MMSE, is recommended in order to identify high-risk patients.

Influence of Cognition on Length of Stay and Rehospitalization in Older Veterans Admitted for Post-Acute Care

OBJECTIVES

Evaluate the relative contribution of cognitive test performance to post-acute care (PAC) length of stay (LOS) and rehospitalization while controlling for key demographic, medical, and functional outcomes.

METHODS

Retrospective medical record review of 160 older Veterans, including cognitive test performance (Addenbrooke's Cognitive Examination-Revised [ACE-R]), on admission to a Veterans Administration Hospital Community Living Center (CLC) PAC.

RESULTS

Individuals with impaired scores on the ACE-R had a longer LOS (10 median days longer; U = 2,547.00, p = .028). Of those rehospitalized, 71.4% (n = 20) screened positive for cognitive impairment. Key medical factors explained the largest amount of variance in CLC-PAC LOS (29.8%), followed by admission ADL (activities of daily living) dependency (4.6%) and ACE-R total score (3.30%).

DISCUSSION

Cognitive screening should be considered on PAC admission, with impairment on ACE-R predicting geriatric rehabilitation outcomes such as risk of increased LOS and rehospitalization.

Vitamin K status and inflammation are associated with cognition in older Irish adults

Studies have shown associations between reduced vitamin K status and poor cognitive function. However, despite this apparent link, direct studies measuring cognitive function, vitamin K status and inflammation are lacking. In the current study, The ELDERMET cohort was investigated to identify associations between cognition, vitamin K status and inflammation. The primary aim of the ELDERMET study was to investigate the relationship between gut bacteria, diet, lifestyle and health in 500 older Irish adults. Significant differences in serum phylloquinone, dietary phylloquinone and inflammatory markers were found across varying levels of cognitive function, after controlling for sex, age, body mass index (BMI), triglycerides and blood pressure. In addition, significantly higher levels of dietary phylloquinone were found in those with better cognition compared to those with the poorest function. Higher levels of inflammatory were also associated with poor cognition. Furthermore, both dietary and serum phylloquinone were significant independent predictors of good cognitive function, after controlling for confounders. This study highlights the importance of dietary vitamin K as a potentially protective cognitive factor; it also provides evidence for the correlation between cognition and inflammation. Strategies should be devised by which elderly populations can access rich dietary sources of phylloquinone to maintain cognition.

Rehabilitation strategy for hip fracture, focused on behavioral psychological symptoms of dementia for older people with cognitive impairment: A nationwide Japan rehabilitation database

The aim is to investigate the relationship between a positive outcome on rehabilitation after hip fracture and behavioral psychological symptoms of dementia (BPSD) transition during rehabilitation. This study is a retrospective cohort study based on the Japan Rehabilitation Database. We recruited 756 subjects 65 years of age or older from 31 hospitals in the database. All subjects were in the hospital as patients undergoing rehabilitation for hip fracture. Functional independence measure (FIM), walking ability, Mini-Mental State Examination (MMSE), and BPSD were measured both at the beginning and at the end of rehabilitation. MMSE for 23 or under was defined as the cognitive-impaired group. MMSE for 24 or over was used as the cognitively intact group. Cognitive impaired participants were divided into four groups: participants presented no BPSD both at the beginning of rehabilitation and at the end of rehabilitation (Group (-/-)), participants presented BPSD at the beginning of rehabilitation but resolved at the end of rehabilitation (Group (+/-)), participants had no BPSD at the beginning of rehabilitation but appeared at the end of rehabilitation (Group (-/+)) and participants had sign of BPSD both at the beginning of rehabilitation and at the end of rehabilitation (Group (+/+)). The endpoints were waking ability, FIM gain. As results, one hundred thirty-seven cognitive-impaired older people patients out of 471 (29.1%) suffered from BPSD at the beginning of rehabilitation. FIM gains in cognitively intact group, Group (-/-), Group (+/-), Group (-/+) and Group (+/+) were 24.8 ± 18.7, 17.5 ± 16.9, 27.3 ± 19.7, 17.8 ± 12.2 and 12.2 ± 17.2, respectively. The Group (+/-) was significantly connected to a positive outcome for rehabilitation. The present study suggested that the management of BPSD can lead to better functional recovery during rehabilitation.

Exercise Intervention Associated with Cognitive Improvement in Alzheimer's Disease

Alzheimer's disease (AD) is a progressive neurodegenerative disease with the syndrome of cognitive and functional decline. Pharmacotherapy has always been in a dominant position for the treatment of AD. However, in most cases, drug therapy is accompanied with clinical delays when older adults have suffered from cognitive decline in episodic memory, working memory, and executive function. On the other hand, accumulating evidence suggests that exercise intervention may ameliorate the progression of cognitive impairment in aging ones while the standard strategy is lacking based on different levels of cognitive decline especially in mild cognitive impairment (MCI) and AD. MCI is the preclinical stage of AD in which neurodegeneration may be reversed via neuroplasticity. Therefore, taking exercise intervention in the early stage of MCI and healthy aging at the risk of AD could slow down the process of cognitive impairment and provide a promising cost-effective nonpharmacological therapy to dementia.

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.

Development of a home-based training program for post-ward geriatric rehabilitation patients with cognitive impairment: study protocol of a randomized-controlled trail

Background

Geriatric patients with cognitive impairment (CI) show an increased risk for a negative rehabilitation outcome and reduced functional recovery following inpatient rehabilitation. Despite this obvious demand, evidence-based training programs at the transition from rehabilitation to the home environments are lacking. The aim of this study is to evaluate the efficacy of a feasible and cost-effective home-based training program to improve motor performance and to promote physical activity, specifically-tailored for post-ward geriatric patients with CI.

Methods

A sample of 101 geriatric patients with mild to moderate stage CI following ward-based rehabilitation will be recruited for a blinded, randomized controlled trial with two arms. The intervention group will conduct a 12 week home-based training, consisting of (1) Exercises to improve strength/power, and postural control; (2) Individual walking trails to enhance physical activity; (3) Implementation of patient-specific motivational strategies to promote behavioral changes. The control group will conduct 12 weeks of unspecific flexibility exercise. Both groups will complete a baseline measurement before starting the program, at the end of the intervention, and after 24 weeks for follow-up. Sensor-based as well as questionnaire-based measures will be applied to comprehensively assess intervention effects. Primary outcomes document motor performance, assessed by the Short Physical Performance Battery, and level of physical activity (PA), as assessed by duration of active episodes (i.e., sum of standing and walking). Secondary outcomes include various medical, psycho-social, various PA and motor outcomes, including sensor-based assessment as well as cost effectiveness.

Discussion

Our study is among the first to provide home-based training in geriatric patients with CI at the transition from a rehabilitation unit to the home environment. The program offers several unique approaches, e.g., a comprehensive and innovative assessment strategy and the integration of individually-tailored motivational strategies. We expect the program to be safe and feasible in geriatric patients with CI with the potential to enhance the sustainability of geriatric rehabilitation programs in patients with CI.

A prospective observational study of outcomes from rehabilitation of elderly patients with moderate to severe cognitive impairment

Objectives:

To evaluate rehabilitation outcomes in patients with moderate to severe cognitive impairment.

Design:

Prospective observational cohort study.

Setting:

Rehabilitation unit for older people.

Subjects:

A total of 116 patients (70F) mean age (SD) 86.3 (6.4). Group 1: 89 patients with moderate cognitive impairment (Mini-Mental State Examination 11–20); and Group 2: 27 patients with severe cognitive impairment (Mini-Mental State Examination 0–10).

Intervention:

A personalised rehabilitation plan.

Main measures:

Barthel Activity of Daily Living score on admission and discharge, length of stay and discharge destination.

Results:

Of 116 patients, 64 (55.2%) showed an improvement in Barthel score. Mini-Mental State Examination was significantly higher in those who improved, 15.4 (SD 3.7) vs.13.2 (SD 5.1): p = 0.01. The mean Barthel score improved in both groups; Group 1 – 14.7 (SD 19.1) vs. Group 2 – 9.3 (SD 16.3): p = 0.17. Of 84 home admissions in Group 1, more patients returning home showed improvements of at least 5 points in the Barthel score compared with nursing/residential home discharges (32/37 – 86.5% vs. 10/28 – 35.7%: p = 0.0001). In Group 2 of 17 home admissions, 6/6 (100%) home discharges showed improvement compared with 3/7 (42.8%) discharges to nursing/residential home (p = 0.07). In Group 1, a discharge home was associated with significantly greater improvement in number of Barthel items than a nursing/residential home discharge (3.27 (SD 2.07) vs. 1.86 (SD 2.32): p = 0.007). A similar non-significant pattern was noted for severe cognitive impairment patients (3.5 (3.06) vs. 1.14 (1.06); p = 0.1).

Conclusion:

Patients with moderate to severe cognitive impairment demonstrated significant improvements in Barthel score and Barthel items showing that such patients can and do improve with rehabilitation.

Defining Rehabilitation Success in Older Adults with Dementia--Results from an Inpatient Geriatric Rehabilitation Unit

OBJECTIVE

To quantify the magnitude of functional recovery in older adults with and without dementia admitted to an inpatient geriatric rehabilitation program by measuring change in measures of global physical function and physical therapy treatment outcomes.

DESIGN

Retrospective cohort study.

SETTING

Rehabilitation academic hospital.

PARTICIPANTS

Consecutive subjects, with (N=65, age 81.9±6.0 y) and without (N=157, age 82.8±7.2 y) a dementia diagnosis, had assessment data at admission and discharge from inpatient geriatric rehabilitation unit.

INTERVENTIONS

Not applicable.

MEASUREMENTS

The Functional Independence Measure (FIM) was used to estimate level of independence on activities of daily living. The Berg Balance Scale (BBS), Timed Up and Go Test (TUG) and 2 Minute Walk Test (2MWT) were used to estimate functional mobility and endurance. The FIM (total, motor subscale, cognitive subscale scores) were used to calculate rehabilitation efficacy and efficiency scores.

RESULTS

After controlling for confounding, there was no group difference for gains on the BBS, TUG, 2MWT; there was no group difference on rehabilitation efficacy and efficiency values based on the FIM motor subscale. The magnitude of the rehabilitation gain using the total FIM score was statistically different between groups, people with dementia having smaller gains.

CONCLUSION

Older adults with a diagnosis of dementia are capable of making motor function recovery during inpatient sub-acute rehabilitation comparable to their peers without a dementia diagnosis. The metric used to evaluate functional recovery influences the determination of rehabilitation success between groups. Rehabilitation success should be defined among people with a dementia diagnosis by a change in the motor subscale of the FIM, rather than the total FIM score or the gain relative to the maximal FIM score.

Outcomes of cognitively impaired older people in Transition Care

AIM

The benefits of Transition Care Programs (TCPs) for patients with cognitive impairment are not well established. This study aimed to investigate the impact of TCP on patients according to their cognitive status.

METHODS

In this prospective cohort study, 351 patients were comprehensively assessed at TCP admission using the interRAI Home Care instrument and divided into two groups based on scores on the Cognitive Performance Scale.

RESULTS

Of 346 patients assessed for cognition, 242 (69.9%) were considered cognitively intact, and 104 (30.1%) were classified as cognitively impaired (Cognitive Performance Scale ≥ 2). There were no significant differences in TCP outcomes between the two groups, including community living at six months (P = 0.1), hospital readmission rates (P = 0.6), or achievement of TCP goals (P = 0.3).

CONCLUSIONS

Cognitively intact and cognitively impaired patients have similar outcomes post-TCP. Older patients should not be refused Transition Care based on the presence of cognitive impairment.

The management of hip fracture in the older population. Joint position statement by Gruppo Italiano Ortogeriatria (GIOG)

This document is a Joint Position Statement by Gruppo Italiano di OrtoGeriatria (GIOG) supported by Società Italiana di Gerontologia e Geriatria (SIGG), and Associazione Italiana Psicogeriatria (AIP) on management of hip fracture older patients. Orthogeriatric care is at present the best model of care to improve results in older patients after hip fracture. The implementation of orthogeriatric model of care, based on the collaboration between orthopaedic surgeons and geriatricians, must take into account the local availability of resources and facilities and should be integrated into the local context. At the same time the programme must be based on the best available evidences and planned following accepted quality standards that ensure the efficacy of the intervention. The position paper focused on eight quality standards for the management of hip fracture older patients in orthogeriatric model of care. The GIOG promotes the development of a clinic database with the aim of obtaining a qualitative improvement in the management of hip fracture.

Association of dementia with early rehospitalization among Medicare beneficiaries

Preventable hospital readmissions have been recognized as indicators of hospital quality, a source of increased healthcare expenditures, and a burden for patients, families, and caregivers. Despite growth of initiatives targeting risk factors associated with potentially avoidable hospital readmissions, the impact of dementia on the likelihood of rehospitalization is poorly characterized. Therefore, the primary objective of this retrospective cohort study was to investigate whether dementia was an independent predictor of 30-day readmissions. Administrative claims data for all admissions to Rhode Island hospitals in 2009 was utilized to identify hospitalizations of Medicare fee-for-service beneficiaries with a diagnosis of Alzheimer's Disease or other dementias. Demographics, measures of comorbid disease burden, and other potential confounders were extracted from the data and the odds of 30-day readmission to any United States hospital was calculated from conditional logistic regression models. From a sample of 25,839 hospitalizations, there were 3908 index admissions of Medicare beneficiaries who fulfilled the study criteria for a dementia diagnosis. Nearly 20% of admissions (n=5133) were followed by a readmission within thirty days. Hospitalizations of beneficiaries with a dementia diagnosis were more likely to be followed by a readmission within thirty days (adjusted odds ratio (AOR) 1.18; 95% CI, 1.08, 1.29), compared to hospitalizations of those of without dementia. Controlling for discharge site of care did not attenuate the association (AOR 1.21; 95% CI, 1.10, 1.33).

How does cognitive impairment impact on functional improvement following the rehabilitation of elderly patients?

AIMS

It has been suggested that patients with cognitive impairment do not benefit from rehabilitation or that rehabilitation gains are reduced. Most studies focus on absolute gain rather than gains in individual functional areas. The Barthel activities of daily living (ADL) score is a tool, which is used widely and comprises 10 functional domains. This study aimed to assess the response to rehabilitation based on improvement or deterioration on the Barthel ADL score for patients with different cognitive abilities

METHODS

This independence measure was assessed at specific time periods in an observational study of 241 patients undergoing in-patient rehabilitation. Therapy was delivered formally by physiotherapists and occupational therapists and also informally by nursing staff. Patients were divided into four groups according to cognition. Group 1 (MMSE, mini-mental state examination 27-30), normal cognition, Group 2 (MMSE 21-26) mild impairment, Group 3 (MMSE 11-20) moderate impairmentand Group 4 (MMSE 0-10) severe impairment.

RESULTS

Statistically significant improvement was made in most of the functional domains by patients with normal cognition and mild cognitive impairment (p < 0.0025). The exception to this for both groups was in the areas of feeding and bowels because of the fact that most patients were independent with these aspects on admission. Group 3 patients made improvements in the domains of grooming, dressing, toileting, transferring and mobility. Group 4 patients did not demonstrate statistically significant improvement in any domain although there were trends for improvement in mobility and transferring.

CONCLUSIONS

This study demonstrated that cognitive impairment did have an impact on the ADL that patients improved in following rehabilitation. However, even patients with moderate cognitive impairment made significant gains with many ADL.

Predictors of functional recovery in patients admitted to geriatric postacute rehabilitation

OBJECTIVE

To examine characteristics associated with functional recovery in older patients undergoing postacute rehabilitation.

DESIGN

Observational study.

SETTING

Postacute rehabilitation facility.

PARTICIPANTS

Patients (N=2754) aged ≥65 years admitted over a 4-year period.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Functional status was assessed at admission and again at discharge. Functional recovery was defined as achieving at least 30% improvement on the Barthel Index score from admission compared with the maximum possible room for improvement.

RESULTS

Patients who achieved functional recovery (70.3%) were younger and were more likely to be women, live alone, and be without any formal home care before admission, and they had fewer chronic diseases (all P<.01). They also had better cognitive status and a higher Barthel Index score both at admission (mean ± SD, 63.3±18.0 vs 59.6±24.7) and at discharge (mean ± SD, 86.8±10.4 vs 62.2±22.9) (all P<.001). In multivariate analysis, patients <75 years of age (adjusted odds ratio [OR]=1.51; 95% confidence interval [CI], 1.16-1.98; P=.003), women (adjusted OR=1.24; 95% CI, 1.01-1.52; P=.045), patients living alone (adjusted OR=1.61; 95% CI, 1.31-1.98; P<.001), and patients without in-home help prior to admission (adjusted OR=1.39; 95% CI, 1.15-1.69; P=.001) remained at increased odds of functional recovery. In addition, compared with those with moderate-to-severe cognitive impairment (Mini-Mental State Examination score <18), patients with mild-to-moderate impairment (Mini-Mental State Examination score 19-23) and those cognitively intact also had increased odds of functional recovery (adjusted OR=1.56; 95% CI, 1.13-2.15; P=.007; adjusted OR=2.21; 95% CI, 1.67-2.93; P<.001, respectively).

CONCLUSIONS

Apart from sociodemographic characteristics, cognition is the strongest factor that identifies older patients more likely to improve during postacute rehabilitation. Further study needs to determine how to best adapt rehabilitation processes to better meet the specific needs of this population and optimize their outcome.

Functional decline in older adults one year after hospitalization

We studied the change in personal ability to perform the activities of daily living (P-ADL) one year after hospitalization (T2) of patients at least 65 years old at baseline (T1). The study included 363 (175 men) medical inpatients with age range 65-98 (mean 80.2, SD 7.5) years. Information was collected at baseline and at a 12 month follow-up using Lawton and Brody's physical self-maintenance scale (PSMS) (termed the P-ADL score), as the dependent variable, and the mini-mental state examination (MMSE), the hospital anxiety and depression scale (HAD) and the WHOQOL-BREF questionnaire as independent variables. For the total sample, the mean P-ADL was significantly worsened from T1 to T2 (mean change 0.5, SD 2.8; p<0.01). In a fully adjusted linear regression analysis, worsened P-ADL from T1 to T2 was independently associated with cognitive impairment at T1, increasing cognitive impairment from T1 to T2, the tendency to fall between T1 and T2, increase in depressive symptoms from T1 to T2, poor physical QOL at T1 and change toward a poorer QOL from T1 to T2. In conclusion, worse P-ADL at T2 was, independently of age and baseline P-ADL, associated with impaired cognitive function and QOL related to physical ability at baseline, as well as worsening depression, cognition and QOL from T1 to T2. Our findings highlight the importance of applying results from screening measures of cognitive function and emotional health when planning care for older people after hospitalization.

Functional improvement in hospitalized older adults is independent of dementia diagnosis: experience of a specialized delirium management unit

BACKGROUND

Patients with delirium, especially when superimposed on dementia, are at high risk of functional decline.

OBJECTIVE

To examine the influence of a multicomponent delirium management program, the geriatric monitoring unit (GMU), on functional progress of delirious older patients and the impact of underlying dementia on functional recovery.

DESIGN

Prospective cohort study.

SETTING

The GMU is a specialized 5-bed unit for the care of delirious older adults within an acute tertiary hospital.

PATIENTS

Patients aged 65 years and older with delirium.

INTERVENTION

The GMU is a multifactorial delirium treatment program with core interventions focusing on early mobilization and rehabilitation.

MEASUREMENTS

Baseline measures included delirium severity (Delirium Rating Scale-98 and Confusion Assessment Method severity), Chinese Mini-Mental State Examination, functional status (modified Barthel Index [MBI]), comorbidity (Charlson's), and illness severity (modified Severity of Illness Index). Patients with and without dementia were compared for recovery in cognitive scores and functional status.

RESULTS

Of 122 patients with delirium who were admitted to the GMU over a 1-year period, 82 (67.2%) had underlying dementia. There were no significant differences in age, gender, delirium severity, illness severity, cognitive performance, and functional status at admission to the GMU between groups, although patients with dementia had significantly higher comorbidity (Charlson's 2.27 vs 1.75, P = 0.05). Significant cognitive and functional improvement was observed for the entire GMU cohort, with demented and nondemented groups capable of functional recovery (MBI gain of 20.43 vs 17.35, respectively, P = 0.35).

CONCLUSION

Elderly patients with dementia recovering from delirium have comparable potential for functional recovery as their cognitively intact counterparts in a delirium management unit focused on geriatric nursing care and rehabilitation.

Independence, institutionalization, death and treatment costs 18 months after rehabilitation of older people in two different primary health care settings

Background

The optimal setting and content of primary health care rehabilitation of older people is not known. Our aim was to study independence, institutionalization, death and treatment costs 18 months after primary care rehabilitation of older people in two different settings.

Methods

Eighteen months follow-up of an open, prospective study comparing the outcome of multi-disciplinary rehabilitation of older people, in a structured and intensive Primary care dedicated inpatient rehabilitation (PCDIR, n=202) versus a less structured and less intensive Primary care nursing home rehabilitation (PCNHR, n=100). Participants: 302 patients, disabled from stroke, hip-fracture, osteoarthritis and other chronic diseases, aged ≥65years, assessed to have a rehabilitation potential and being referred from general hospital or own residence. Outcome measures: Primary: Independence, assessed by Sunnaas ADL Index(SI). Secondary: Hospital and short-term nursing home length of stay (LOS); institutionalization, measured by institutional residence rate; death; and costs of rehabilitation and care. Statistical tests: T-tests, Correlation tests, Pearson’s χ², ANCOVA, Regression and Kaplan-Meier analyses.

Results

Overall SI scores were 26.1 (SD 7.2) compared to 27.0 (SD 5.7) at the end of rehabilitation, a statistically, but not clinically significant reduction (p=0.003 95%CI(0.3-1.5)). The PCDIR patients scored 2.2points higher in SI than the PCNHR patients, adjusted for age, gender, baseline MMSE and SI scores (p=0.003, 95%CI(0.8-3.7)). Out of 49 patients staying >28 days in short-term nursing homes, PCNHR-patients stayed significantly longer than PCDIR-patients (mean difference 104.9 days, 95%CI(0.28-209.6), p=0.05). The institutionalization increased in PCNHR (from 12%-28%, p=0.001), but not in PCDIR (from 16.9%-19.3%, p= 0.45). The overall one year mortality rate was 9.6%. Average costs were substantially higher for PCNHR versus PCDIR. The difference per patient was 3528€ for rehabilitation (p<0.001, 95%CI(2455–4756)), and 10134€ for the at-home care (p=0.002, 95%CI(4066–16202)). The total costs of rehabilitation and care were 18702€ (=1.6 times) higher for PCNHR than for PCDIR.

Conclusions

At 18 months follow-up the PCDIR-patients maintained higher levels of independence, spent fewer days in short-term nursing homes, and did not increase the institutionalization compared to PCNHR. The costs of rehabilitation and care were substantially lower for PCDIR. More communities should consider adopting the PCDIR model.
