The association between patients' cognitive status and rehabilitation outcome in a geriatric day hospital

Peripheral Parenteral Nutrition and Activities of Daily Living in Hospitalized Older Frail Patients

BACKGROUND

Frail older adults require nursing care following hospitalization for acute illnesses. Frailty is reversible, and appropriate nutritional management and rehabilitation during hospitalization are essential. However, optimal nutritional management for patients who are unable to obtain adequate nutrition via oral intake has not been established. We aimed to determine whether peripheral parenteral nutrition (PPN) promotes the recovery of activities of daily living (ADLs) in frail older patients.

METHODS

This was a retrospective, observational cohort study conducted at the General Medicine Department of Aomori Prefectural Central Hospital in Aomori, Japan. The primary outcome was recovery of the Barthel index (BI) from the beginning of rehabilitation to discharge, and the secondary outcomes were the proportion of patients transferred for rehabilitation and the nutritional status.

RESULTS

In total, 342 patients hospitalized during the period of April 2018 to January 2022 were included, of whom 127 (37.1%) received PPN and 215 (62.9%) did not. Contrary to our expectations, recovery of the BI was lower in the PPN group than that in the non-PPN group (12.2 (95% confidence interval (CI): 8.5-16.0) vs. 22.4 (18.8-23.0); p < 0.01). Multivariable analysis revealed PPN as an independent risk factor for poor BI recovery (mean difference = -7.3 (95% CI = -12.7 to -1.9)).

CONCLUSION

Nutritional management through PPN for frail older adults may not improve physical activity. The nutritional management of frail patients with inadequate oral intake remains challenging.

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.

Impact of a Geriatric Day Hospital Program on Older Adults' Functional Independence and Caregiver Stress: A Non-Experimental, Single Group Pre-/Posttest Study

Objective: To evaluate the impact of a geriatric day hospital program on older adults’ functional independence and on caregiver stress. Methods: We used a single group pre- and posttest design. The data were collected through chart reviews and follow-up phone calls. Outcomes included fear of falling, balance, functional exercise capacity (walking distance), and caregiver stress. Descriptive statistics were used for sociodemographic data, dependent t test for paired samples of normally distributed data, and the Wilcoxon signed-rank test for determining differences between nonnormally distributed data sets. Results: We found a statistically significant difference in pre (33.54) and post (27.47) mean rank scores for fear of falling (Z = −3.895, P < .001), pre (49.5) and post (59.42) scores for balance (Z = −8.725, P < .001), and pre (250.07 m) and post (291.20 m) for functional exercise capacity (P < .001). No statistically significant difference was found with respect to caregiver stress pre (22.05) and post (19.90) scores (Z = −0.422, P = .673). Discussion: Future research may consider approaching evaluative studies of a similar type using not only quantitative but also qualitative methods to obtain a more comprehensive understanding of older adults’ functional ability and caregiver stress before and after participating in a geriatric day hospital program.

How much do combined affective and cognitive impairments worsen rehabilitation outcomes after hip fracture ?

Background

To investigate the association between isolated and combined affective and cognitive impairments with functional outcomes and discharge destination in older patients admitted to rehabilitation after a hip fracture.

Methods

Prospective study in 612 community-dwelling patients aged 65 years and over, admitted to rehabilitation after surgery for hip fracture. Information on socio-demographics, medical, functional, affective, and cognitive status was systematically collected at admission. Functional status, length of stay and destination were assessed at discharge. Functional improvement was defined as any gain on the Barthel Index score between admission and discharge from rehabilitation.

Results

At admission, 8.2% of the patients had isolated affective impairment, 27.5% had cognitive impairment only, and 7.5% had combined impairments. Rate of functional improvement steadily decreased from 91.2% in patients with no cognitive nor affective impairment to 73.8% in those with combined impairments. Compared to patients without any impairment, those with combined impairments had lower odds of functional improvement, even after adjustment for age, gender, health and functional status at admission (adjOR: 0.40; 95%CI: 0.16–1.0; p = .049). The proportion of patients discharged back home gradually decreased from 82.8% among patients without any impairment to only 45.6% in patients with combined impairments. In multivariate analysis, the odds of returning home remained significantly reduced in these latter patients (adjOR: 0.31; 95%CI:0.15–0.66; p = .002).

Conclusions

Affective and cognitive impairments had both independent, and synergistic negative association with functional outcome and discharge destination in patients admitted to rehabilitation after a hip fracture. Nevertheless, patients with combined affective and cognitive impairments still achieved significant functional improvement, even though its magnitude was reduced. Further studies should investigate whether these patients would benefit from better targeted, longer, or more intensive rehabilitation interventions to optimize their functional recovery.

Understanding the Connection between Cognitive Impairment and Mobility: What Can Be Gained from Neuropsychological Assessment?

The ability of neuropsychological tests to predict rehabilitation outcome is unclear, particularly when other ratings of cognition are available. Neuropsychological test scores and functional ratings of cognition (Functional Independence Measure (FIM) Cognition score) were used to predict improvement in patient mobility and self-care skill, as measured by the FIM Motor score. Regression models used both raw neuropsychology test scores and age-adjusted scores. Retrospective chart review was performed for patients on an inpatient rehabilitation unit and referred for neuropsychological assessment. The group included 126 subjects (average age 64.2 ± 17.1 years) and a variety of medical diagnoses. Neuropsychological tests included the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). After forcing the Admission FIM Cognition score into the model, RBANS scores and duration of rehabilitation predicted FIM Motor improvements (F = 11.42, p < 0.0001). Raw neuropsychological test scores performed better than the model with age-adjusted test scores. FIM Cognition alone did not predict FIM Motor improvements. Neuropsychological tests, combined with duration of rehabilitation, predicted mobility gains for patients undergoing inpatient rehabilitation beyond what was predicted by another, readily available, assessment of cognition. Neuropsychology raw scores performed better than age-adjusted scores, raising questions about the standard use of demographic adjustments for predicting real-world function.

Medical day hospital care for older people versus alternative forms of care

BACKGROUND

The proportion of the world's population aged over 60 years is increasing. Therefore, there is a need to examine different methods of healthcare provision for this population. Medical day hospitals provide multidisciplinary health services to older people in one location.

OBJECTIVES

To examine the effectiveness of medical day hospitals for older people in preventing death, disability, institutionalisation and improving subjective health status.

SEARCH METHODS

Our search included the Cochrane Effective Practice and Organisation of Care (EPOC) Group Register of Studies, CENTRAL (2013, Issue 7), MEDLINE via Ovid (1950-2013 ), EMBASE via Ovid (1947-2013) and CINAHL via EbscoHost (1980-2013). We also conducted cited reference searches, searched conference proceedings and trial registries, hand searched select journals, and contacted relevant authors and researchers to inquire about additional data.

SELECTION CRITERIA

Randomised and quasi-randomised trials comparing medical day hospitals with alternative care for older people (mean/median > 60 years of age).

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial eligibility and risk of bias and extracted data from included trials. We used standard methodological procedures expected by the Cochrane Collaboration. Trials were sub-categorised as comprehensive care, domiciliary care or no comprehensive care.

MAIN RESULTS

Sixteen trials (3689 participants) compared day hospitals with comprehensive care (five trials), domiciliary care (seven trials) or no comprehensive care (four trials). Overall there was low quality evidence from these trials for the following results.For the outcome of death, there was no strong evidence for or against day hospitals compared to other treatments overall (odds ratio (OR) 1.05; 95% CI 0.85 to 1.28; P = 0.66), or to comprehensive care (OR 1.26; 95% CI 0.87 to 1.82; P = 0.22), domiciliary care (OR 0.97; 95% CI 0.61 to 1.55; P = 0.89), or no comprehensive care (OR 0.88; 95% CI 0.63 to 1.22; P = 0.43).For the outcome of death or deterioration in activities of daily living (ADL), there was no strong evidence for day hospital attendance compared to other treatments (OR 1.07; 95% CI 0.76 to 1.49; P = 0.70), or to comprehensive care (OR 1.18; 95% CI 0.63 to 2.18; P = 0.61), domiciliary care (OR 1.41; 95% CI 0.82 to 2.42; P = 0.21) or no comprehensive care (OR 0.76; 95% CI 0.56 to 1.05; P = 0.09).For the outcome of death or poor outcome (institutional care, dependency, deterioration in physical function), there was no strong evidence for day hospitals compared to other treatments (OR 0.92; 95% CI 0.74 to 1.15; P = 0.49), or compared to comprehensive care (OR 1.05; 95% CI 0.79 to 1.40; P = 0.74) or domiciliary care (OR 1.08; 95% CI 0.67 to 1.74; P = 0.75). However, compared with no comprehensive care there was a difference in favour of day hospitals (OR 0.72; 95% CI 0.53 to 0.99; P = 0.04).For the outcome of death or institutional care, there was no strong evidence for day hospitals compared to other treatments overall (OR 0.85; 95% CI 0.63 to 1.14; P = 0.28), or to comprehensive care (OR 1.00; 95% CI 0.69 to 1.44; P = 0.99), domiciliary care (OR 1.05; 95% CI 0.57 to1.92; P = 0. 88) or no comprehensive care (OR 0.63; 95% CI 0.40 to 1.00; P = 0.05).For the outcome of deterioration in ADL, there was no strong evidence that day hospital attendance had a different effect than other treatments overall (OR 1.11; 95% CI 0.68 to 1.80; P = 0.67) or compared with comprehensive care (OR 1.21; 0.58 to 2.52; P = 0.61), or domiciliary care (OR 1.59; 95% CI 0.87 to 2.90; P = 0.13). However, day hospital patients showed a reduced odds of deterioration compared with those receiving no comprehensive care (OR 0.61; 95% CI 0.38 to 0.97; P = 0.04) and significant subgroup differences (P = 0.04).For the outcome of requiring institutional care, there was no strong evidence for day hospitals compared to other treatments (OR 0.84; 95% CI 0.58 to 1.21; P = 0.35), or to comprehensive care (OR 0.91; 95% CI 0.70 to 1.19; P = 0.49), domiciliary care (OR 1.49; 95% CI 0.53 to 4.25; P = 0.45), or no comprehensive care (OR 0.58; 95% CI 0.28 to 1.20; P = 0.14).

AUTHORS' CONCLUSIONS

There is low quality evidence that medical day hospitals appear effective compared to no comprehensive care for the combined outcome of death or poor outcome, and for deterioration in ADL. There is no clear evidence for other outcomes, or an advantage over other medical care provision.

Rehabilitation therapies for older clients of the Ontario home care system: regional variation and client-level predictors of service provision

PURPOSE

To examine regional variation in service provision and identify the client characteristics associated with occupational therapy (OT) and physiotherapy (PT) services for older adults in the Ontario Home Care System.

METHODS

Secondary analyses of a provincial database containing comprehensive assessments (RAI-HC) linked with service utilization data from every older long-stay home care client in the system between 2005 and 2010 (n = 299 262). Hierarchical logistic regression models were used to model the dependent variables of OT and PT service use within 90 d of the initial assessment.

RESULTS

Regional differences accounted for 9% of the variation in PT service provision and 20% of OT service provision. After controlling for the differences across regions, the most powerful predictors of service provision were identified for both OT and PT. The most highly associated client characteristics related to PT service provision were hip fracture, impairments in activities of daily living/instrumental activities of daily living, cerebrovascular accidents, and cognitive impairment. For OT, hazards in the home environment was the most powerful predictor of future service provision.

CONCLUSIONS

Where a client lived was an important determinant of service provision in Ontario, raising the possibility of inequities in access to rehabilitation services. Health care planners and policy makers should review current practices and make adjustments to meet the increasing and changing needs for rehabilitation therapies of the aging population. Implications for Rehabilitation For older adults in home care, the goal of rehabilitation therapy services is to allow individuals to maintain or improve physical functioning, quality of life and overall independence while living within their community. Previous research has demonstrated that a large proportion of home care clients specifically identified as having rehabilitation potential do not receive it. This article used clinical assessment data to identify the predictors of and barriers to rehabilitation services for older adults in the Ontario Home Care System. Barriers of PT included dementia diagnosis and French as a first language. Barriers to OT included dementia diagnosis. Policies and practices related to service provision for older adults should be reconsidered if we are going to meet the demands of aging populations and increasing rates of functional and cognitive impairments.

Rehabilitation impact indices and their independent predictors: a systematic review

OBJECTIVES

To (1) identify all available rehabilitation impact indices (RIIs) based on their mathematical formula, (2) assess the evidence for independent predictors of each RII and (3) propose a nomenclature system to harmonise the names of RIIs.

DESIGN

Systematic review.

DATA SOURCES

PubMed and references in primary articles.

STUDY SELECTION

First, we identified all available RII through preliminary literature review. Then, various names of the same formula were used to identify studies, limited to articles in English and up to 31 December 2011, including case-control and cohort studies, and controlled interventional trials where RIIs were outcome variable and matching or multivariate analysis was performed.

RESULTS

The five RIIs identified were (1) absolute functional gain (AFG)/absolute efficacy/total gain, (2) rehabilitation effectiveness (REs)/Montebello Rehabilitation Factor Score (MRFS)/relative functional gain (RFG), (3) rehabilitation efficiency (REy)/length of stay-efficiency (LOS-EFF)/efficiency, (4) relative functional efficiency (RFE)/MRFS efficiency and (5) revised MRFS (MRFS-R). REy/LOS-EFF/efficiency had the most number of supporting studies, followed by REs and AFG. Although evidence for different predictors of RIIs varied according to the RII and study population, there is good evidence that older age, lower prerehabilitation functional status and cognitive impairment are predictive of poorer AFG, REs and REy.

CONCLUSIONS

5 RIIs have been developed in the past two decades as composite rehabilitation outcome measures controlling premorbid and prerehabilitation functional status, rate of functional improvement, each with varying levels of evidence for its predictors. To address the issue of multiple names for the same RII, a new nomenclature system is proposed to harmonise the names based on common mathematical formula and a first-named basis.

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.

[The neurological state and cognition of patients after a stoke]

The objective of this study was to have a multidisciplinary team investigate the neurological state and cognitive performance of patients after a stroke, through a cross-sectional study with 45 patients in rehabilitation after having an acute stroke. The data collection instruments used were an assessment sheet, the Mini Mental-MEEM, and the National International Health Stroke Scale-NIHSS. The sample consisted mostly of women (55.6%), Ischemic Stroke (86.7%), right hemisphere of the brain (60%) and Educated (68.8%). The mean MEEM for educated and illiterate patients was 19.3 ± 5.0 and 15.92 ± 3.7, respectively. The overall mean of the neurological state was 13.0±4.8. A significant difference was found between the cognitive means of patients in terms of education (p value=0.017), and there was a significant relationship between the neurological state and cognitive performance (r=-0.44 p value=0.002). It appears to be a direct relationship between the neurological state and cognition performance of patients after an acute stroke, which evinces the need for greater attention to the cognitive issue involved early in rehabilitation.

Identification of factors associated with a need for rehabilitation for patients over 65 years following admission to a general and vascular surgical service

AIM

  To identify factors that predict admission to a rehabilitation hospital for patients over 65 years of age.

METHODS

  This study reviewed the destinations of all patients over 65 years admitted to a Department of General and Vascular Surgery over 1 year to analyse factors associated with subsequent admission to a rehabilitation hospital. Data recorded included demographic characteristics, type of admission, length of stay at the primary hospital, operation, speciality type, previous admission to rehabilitation hospital, diagnoses and procedures.

RESULTS

  Of the 2632 patients examined, 8.7% were subsequently admitted to a rehabilitation hospital. Multivariate analysis showed that previous admission to the rehabilitation hospital, increasing age, number of diagnoses and admission under vascular service were all independently associated with admission for rehabilitation.

CONCLUSIONS

  Factors associated with increased risk of requiring transfer to a rehabilitation hospital can be identified. This allows early recognition of at-risk patients.

The Montreal Cognitive Assessment (MoCA) in geriatric rehabilitation: psychometric properties and association with rehabilitation outcomes

BACKGROUND

Cognitive status has been reported to be an important predictor of rehabilitation outcome. The Montreal Cognitive Assessment (MoCA) was designed to overcome some of the limitations of established cognitive screening tools such as the Mini-Mental State Examination (MMSE). The purpose of this study is to evaluate the psychometric characteristics of the MoCA as a screening tool in a geriatric rehabilitation program and its ability to predict rehabilitation outcome.

METHODS

Forty-seven geriatric rehabilitation program patients participated in the study. Assessments of each patient's functional (Functional Independence Measure) and cognitive status (MMSE and MoCA) were performed. Information on discharge destinations were obtained and rehabilitation efficacy and efficiency scores were calculated.

RESULTS

Significant correlations were found between the MoCA and other cognitive status measures. Cognitive status at admission and successful rehabilitation were also associated. Defining rehabilitation success on the basis of relative functional efficacy (an indicator that includes the patient's potential for improvement), the sensitivity and specificity of the MoCA were 80% and 30% respectively. The attention subscale of the MoCA was also uniquely predictive of rehabilitation success. The attention subscale (cutoff 5/6) of the MoCA had a sensitivity of 40% and specificity of 90%, as did the MMSE.

CONCLUSIONS

As a cognitive screening tool, the MoCA appears to have acceptable psychometric properties. Results suggest that the MoCA can have a considerable advantage over the MMSE in sensitivity and equivalence in specificity using both total and attention scale scores. The MoCA may be a more useful measure for detecting cognitive impairment and predicting rehabilitation outcome in this population.

Predicting functional outcomes in patients suffering from ischaemic stroke using initial admission variables and physiological data: a comparison between tree model and multivariate regression analysis

PURPOSE

This study was aimed to compare the application of a tree model and regression approach for developing data-driven models that identified frisk factors related to functional outcomes among ischaemic stroke patients.

METHODS

Data were derived from 271 hospitalised patients with a first-ever ischaemic stroke. The Barthel Index (BI) and Modified Rankin Scale (MRS) were used to assess the functional outcomes. The stroke severity at admission and related information from 2006 to December 2007 were extracted retrospectively from a chart review.

RESULTS

In the regression approach, including age, the National Institutes of Health Stroke Scale (NIHSS) score and glucose level were the most significant predictors affecting both the BI and MRS. After applying the tree model, different tree structures were found. For the BI score, the NIHSS score interact with glucose, age and systolic blood pressure to form the tree structure. By contrast, the NIHSS score mainly interact with patients' age to form the tree model for MRS.

CONCLUSION

Both models have their pros and cons. The tree model otherwise provides risk interactions, and can effectively discriminate the risk groups for different functional outcomes. Applying both models to specific situations will provide a different angle for functional assessment and intervention in stroke rehabilitation.

Do cognitively impaired patients benefit from rehabilitation?

Rehabilitation in broad terms is a process aimed at restoring a person's functional capacity particularly in relation to activities of daily living. Studies have shown that hospitalization of older patients is a major risk factor for an often irreversible decline in function, and that functional decline from baseline occurs as early as day two of admission. Rehabilitation is therefore often required for older patients following an admission to an acute hospital. Older patients admitted for rehabilitation are more likely to be functionally impaired and are more medically complex than younger patients.

Factors Affecting Short-Term Rehabilitation Outcomes of Disabled Elderly Patients With Proximal Hip Fracture

OBJECTIVE

To identify factors associated with postacute rehabilitation outcome of disabled elderly patients with proximal hip fracture.

SETTING

Geriatric rehabilitation center.

PARTICIPANTS

One hundred thirty-three older patients.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

FIM instrument, motor FIM score, absolute functional gain on the FIM and motor FIM scores, relative functional gain on the FIM and motor FIM scores, rate of improvement on the FIM and motor FIM scores, proportion of patients discharged to home, and length of stay (LOS).

RESULTS

Mean FIM score improved by 14 points (22%) with a functional gain rate of .56 point per day. No significant differences (P>.05) were found between weight-bearing and non-weight-bearing patients regarding the above outcome measures. Functionally independent and cognitively intact patients achieved significantly better score changes and rates of improvement and showed a higher ability to extract their rehabilitation potential than dependent and cognitively impaired patients. Their LOSs were significantly shorter. Patients with latency time (time delay from fracture to operation) of more than 5 days and patients with a history of stroke had significantly longer LOSs. Mini-Mental State Examination score, albumin levels on admission, and prefracture functional status were the most important parameters associated with FIM discharge scores (r=.756) and relative functional gain on the FIM (r=.583). Depression was the most important factor associated with LOS in patients with weight-bearing instructions on admission. The presence of a caregiver was the significant predictive value variable for returning home.

CONCLUSIONS

Cognitive function, nutritional status, preinjury functional level, and depression were the most important prognostic factors associated with rehabilitation success of older patients with proximal hip fracture. Of these, depression and nutritional status are correctable, and early intervention may improve rehabilitation outcome.
