A comprehensive psychometric evaluation of the UK FIM + FAM

The use of frailty questionnaires in inpatients in two neurorehabilitation units in the East Midlands - A cross-sectional cohort study with follow-up to 1-year after discharge from inpatient rehabilitation

BACKGROUND

Frailty correlates with poor clinical outcomes and is not routinely assessed in neurorehabilitation inpatient settings.

METHODS

We recruited adults from two neurorehabilitation units. We administered six validated tools for assessing frailty and collected data around length of stay, discharge, readmission and change in rehabilitation outcome measures.

RESULTS

Seventy-eight participants aged between 31 and 84 years were recruited with a range of neurological diagnoses. Frailty prevalence ranged between 23% and 46%, depending on the scale used, with little agreement between tools. Frailty status did not correlate with age, gender, length of stay, discharge destination and rehabilitation outcome measures. One-year readmission was higher in participants rated as frail by the Frail-Non-Disabled Questionnaire, the FRESH-screening questionnaire and the Clinical Frailty Scale.

CONCLUSION

Frailty ascertainment was variable depending on the tool used. Three frailty indices predicted readmission rate at 1 year but no other outcome measures. Therefore, frailty tools may have limited utility in this clinical population.

Development of a menu of recovery goals to facilitate goal setting after critical illness

OBJECTIVE

To develop an expert-informed (including end users) recovery goal menu for adults recovering from critical illness applicable to the community/home setting.

RESEARCH METHODOLOGY/DESIGN

Stage 1 Item generation: iterative development of domains, sub-domains, and goals in consultation with former intensive care patients, family members and expert clinicians. Stage 2 Content validity assessment: cognitive interviews and the content validity index.

SETTING

Virtual consultation meetings facilitated by the research team at King's College London and Guy's and St Thomas' NHS Foundation Trust.

MAIN OUTCOME MEASURES

Content validity as assessed by: the Item-Content Validity Index (I-CVI), Scale Level-Content Validity Index/Universal Agreement (S-CVI/UA) score, the Scale Level-Content Validity Index/Average (S-CVI/Ave) score and Average Content Validity Ratio (CVR).

RESULTS

Item generation resulted in a goal menu comprising 4 domains, 22 sub-domains and 95 goals assigned as follows: Self-care: 9 sub-domains with 37 goals, Productivity: 7 sub-domains with 13 goals, Leisure: 3 sub-domains with 25 goals, and Person domain 3 sub-domains with 20 goals. Cognitive interviews resulted in addition of 79 goals and modification of 7, addition of 4 new sub-domains and modification of 4, thus resulting in 4 domains, 26 sub-domains with a total of 174 goals. Twenty-four sub-domains (169 goals) were deemed relevant with Item-Content Validity Index (I-CVI) scores ranging from 0.72 to 1. Two sub-domains (5 goals) did not meet the 0.7 cut-off and were removed. The Scale Level-Content Validity Index/Universal Agreement (S-CVI/UA) score was 0.46; the Scale Level-Content Validity Index/Average (S-CVI/Ave) 0.91. Average Content Validity Ratio (CVR) was 0.93.

CONCLUSION

An expert informed recovery goal menu for former intensive care patients has been developed with excellent content validity. The final goal menu comprises 169 goals within 24 sub-domains grouped under 4 domains.

IMPLICATIONS FOR CLINICAL PRACTICE

This menu will help patients to set goals and increase our understanding of how individuals recover from critical illness.

Sex/gender differences in service use patterns, clinical outcomes and mortality risk for adults with acquired brain injury: a retrospective cohort study (ABI-RESTART)

OBJECTIVE

To identify sex/gender differences in functional, psychosocial and service use patterns in community-based post-acute care for acquired brain injury.  Design: Retrospective cohort study.

SUBJECTS/PATIENTS

Adults with acquired brain injury enrolled in post-acute neurorehabilitation and disability support in Western Australia (n = 1,011).

METHODS

UK Functional Independence Measure and Functional Assessment Measure (FIM + FAM), Mayo-Portland Adaptability Inventory-4, goal attainment, length of stay (LOS), number of episodes of care and deaths were evaluated using routinely collected clinical and linked administrative data.

RESULTS

At admission, women were older (p < 0.001) and displayed poorer functional independence (FIM + FAM; p < 0.05) compared with men. At discharge, there were no differences in goal attainment, psychosocial function or functional independence between men and women. Both groups demonstrated functional gains; however, women demonstrated clinically significant gains (+ 15.1, p < 0.001) and men did not (+ 13.7, p < 0.001). Women and men had equivalent LOS (p = 0.205). Aboriginal and/or Torres Strait Islander status predicted longer LOS for women but not for men. Being partnered predicted reduced LOS for women but not men. Women had a higher risk of multiple episodes of care (p < 0.001), but not death (p = 0.409), compared with that of men.

CONCLUSION

At admission to rehabilitation and disability support services for acquired brain injury, women have poorer functional independence and higher risk of multiple episodes of care, compared with men, suggesting greater disability in the community. By the time of discharge from these services, women and men make equivalent functional and psychosocial gains. The higher risk of multiple episodes of care for women relative to men suggest women may need additional post-discharge support, to avoid readmission.

Prediction of emergence from prolonged disorders of consciousness from measures within the UK rehabilitation outcomes collaborative database: a multicentre analysis using machine learning

PURPOSE

Predicting emergence from prolonged disorders of consciousness (PDOC) is important for planning care and treatment. We used machine learning to examine which variables from routine clinical data on admission to specialist rehabilitation units best predict emergence by discharge.

MATERIALS AND METHODS

A multicentre national cohort analysis of prospectively collected clinical data from the UK Rehabilitation Outcomes (UKROC) database 2010-2018. Patients (n = 1170) were operationally defined as "still in PDOC" or "emerged" by their total UK Functional Assessment Measure (FIM + FAM) discharge score. Variables included: Age, aetiology, length of stay, time since onset, and all items of the Neurological Impairment Scale, Rehabilitation Complexity Scale, Northwick Park Dependency Scale, and the Patient Categorisation Tool. After filtering, prediction of emergence was explored using four techniques: binary logistic regression, linear discriminant analysis, artificial neural networks, and rule induction.

RESULTS

Triangulation through these techniques consistently identified characteristics associated with emergence from PDOC. More severe motor impairment, complex disability, medical and behavioural instability, and anoxic aetiology were predictive of non-emergence, whereas those with less severe motor impairment, agitated behaviour and complex disability were predictive of emergence.

CONCLUSIONS

This initial exploration demonstrates the potential opportunities to enhance prediction of outcome using machine learning techniques to explore routinely collected clinical data. Implications for rehabilitationPredicting emergence from prolonged disorders of consciousness is important for planning care and treatment.Few evidence-based criteria exist for aiding clinical decision-making and existing criteria are mostly based upon acute admission data.Whilst acknowledging the limitations of using proxy data for diagnosis of emergence, this study suggests that key items from the UKROC dataset, routinely collected on admission to specialist rehabilitation some months post injury, may help to predict those patients who are more (or less) likely to regain consciousness.Machine learning can help to enhance our understanding of the best predictors of outcome and thus assist with clinical decision-making in PDOC.

Reliability and validity of the Spanish adaptation of the Functional Independence Measure + Functional Assessment Measure

BACKGROUND

The Functional Independence Measure + Functional Assessment Measure (FIM+FAM) Scale is one of the most widely used instruments to measure functional independence post-stroke, and features many cultural adaptations to various languages.

AIM

The aim of this study was to determine the psychometric properties of a Spanish cross-cultural adaptation of the FIM+FAM for use in the stroke population.

DESIGN

Observational study.

SETTING

Outpatient long-term service of a neurorehabilitation unit.

POPULATION

One hundred and twenty-two individuals with stroke.

METHODS

The functional independence of the participants was assessed with the adapted version of the FIM+FAM. Additionally, the functional, motor and cognitive condition of the participants was assessed with a battery of standardized clinical instruments. Finally, a group of 31 participants out of the total were evaluated a second time with the FIM+FAM by a different evaluator than the one who performed the first evaluation. Internal consistency, inter-rater reliability and convergent validity with other clinical instruments of the adapted version of the FIM+FAM were determined.

RESULTS

The internal consistency of the adapted version of the FIM+FAM was excellent, as evidenced by Cronbach's α values that exceeded 0.973. The inter-rater reliability was likewise excellent, with correlations above 0.990 in all domains and subscales. Additionally, the convergent validity of the scale adaptation with clinical instruments was variable, with values ranging from 0.264 to 0.983, but consistent with the construct assessed in the different instruments examined.

CONCLUSIONS

The internal consistency, inter-rater reliability and convergent validity of the Spanish-adapted version of the FIM+FAM Scale showed excellent reliability and validity of the adaptation, which supports its use to assess functional independence after stroke.

CLINICAL REHABILITATION IMPACT

Availability of a valid adaptation for the evaluation of functional independence after stroke in Spanish population.

Change in care hours, cost, and functional independence following continence and assistive technology intervention in an acquired brain injury population

PURPOSE

After acquired brain injury (ABI) dependence on intervention for continence management is common. This preliminary investigation aimed to (i) quantify toileting care hours and costs in a community-based ABI rehabilitation and disability setting, and (ii) measure change in care needs, costs, and functional independence after intervention with assistive technologies (ATs).

METHOD

Pragmatic pre-post intervention pilot study of 14 adults with ABI and toileting disability accessing community-based neurorehabilitation or disability support in Western Australia. Toileting and functional independence were assessed monthly from baseline (T₀) to 3-month follow-up (T₃). Basic and nursing care hours (Northwick Park Dependency Score), cost of care estimates (Northwick Park Care Needs Assessment), functional independence (Functional Independence and Assessment Measure), and cost of consumables were examined pre- and post-intervention with ATs. Multilevel mixed-effects models with bootstrap estimation were conducted.

RESULTS

Cost of consumables significantly declined (AU$69/week), and functional independence significantly improved following intervention (+23.5 points). There was a non-significant reduction in care needs for toileting (4 h/week) and in the cost of toileting care (AU$633/week).

CONCLUSION

Toileting disability substantially impacts care hours and costs. This study provides preliminary evidence that comprehensive continence management is beneficial in reducing costs and supporting people with an ABI to increase their independence.IMPLICATIONS FOR REHABILITATIONA comprehensive continence assessment and management plan reduces the number of care hours, cost of care, and cost of continence products in a neurorehabilitation and disability support sample for people with acquired brain injury (ABI).Assistive technologies for continence management are beneficial in supporting people with ABI to increase independence, and reduce costs.Providing comprehensive continence assessment and management plan reduces reliance on staff for continence care, and improves functional independence.

Prolonged disorders of consciousness: identification using the UK FIM + FAM and cohort analysis of outcomes from a UK national clinical database

PURPOSE

1: To determine whether Total UK FIM + FAM scores can identify patients in VS/MCS. 2: Using the identified cut-off points, to examine outcomes from specialist rehabilitation.

METHODS

Part 1: Retrospective analysis of a consecutive clinical cohort (n = 388) presenting to a single specialist PDOC evaluation programme 2007-2021. FIM + FAM scores were analysed by PDOC diagnosis to define cut-off points for vegetative (VS) and minimally conscious states (MCS). Part 2: Multicentre cohort analysis of prospectively-collected clinical outcomes data from the UK Rehabilitation Outcomes Collaborative database of adults in PDOC registered 2011-2020 (n = 2384 in 68 centres).

RESULTS

Cut-off points of ≤31 and 32-35 in FIM + FAM total scores respectively identified patients in VS/MCS-Minus and MCS-Plus. Approximately 365 PDOC patients are admitted to specialist rehabilitation units in England each year. By discharge, 43% have emerged into consciousness and demonstrate a wide range of disability. A few reached full independence, but the majority remained severely dependent. Nevertheless, those who emerged generated mean net life-time savings of over £436,000 (£400 million for this cohort).

CONCLUSION

In absence of a dedicated PDOC registry, FIM + FAM scores can identify patients in VS/MCS at population level. Identifying those who emerge and providing timely rehabilitation generates cost-savings well-exceeding the cost of the evaluation/rehabilitation programme.Implications for rehabilitationThe UK National Health Service currently collects no systematic data to identify patients in PDOC, so we have no accurate information on how many patients there are, where they are managed or what their outcomes are.In the absence of more direct data, total FIM + FAM scores of < =31 and 32-35 respectively can be used to identify patients in vegetative and minimally conscious states.Of the 365 or so patients admitted to specialist rehabilitation units per year, 43% emerge into consciousness leaving about 150 patients per year in PDOC states that are likely to be permanent.Identifying those who emerge and providing timely rehabilitation generates cost-savings that pay for the entire PDOC evaluation/rehabilitation programme many times over.

A Cross-Sectional Study: Determining Factors of Functional Independence and Quality of Life of Patients One Month after Having Suffered a Stroke

(1) Background: loss of quality of life (QoL) and functional independence are two of the most common consequences of suffering a stroke. The main objective of this research is to study which factors are the greatest determinants of functional capacity and QoL a month after suffering a stroke so that they can be considered in early interventions. (2) Methods: a cross-sectional study was conducted which sample consisted of 81 people who had previously suffered a stroke. The study population was recruited at the time of discharge from the Neurology Service and Stroke Unit of the hospitals of Burgos and Córdoba, Spain, through a consecutive sampling. Data were collected one month after participants experienced a stroke, and the main study variables were quality of life, measured with the Stroke-Specific Quality of Life Measure (NEWSQOL), and functional independence, measured with the Functional Independence Measure-Functional Assessment Measure (FIM-FAM). (3) Results: the factors associated with a worse QoL and functional capacity one month after having suffered a stroke were living in a different dwelling than the usual flat or house (p < 0.05), a worse cognitive capacity (p < 0.001) and a worse functional capacity of the affected upper limb (p < 0.001). A higher age was related to a worse functional capacity one month after suffering a stroke (p = 0.048). (4) Conclusions: the type of dwelling, age, cognitive ability and functional capacity of the affected upper limb are determining aspects in functional independence and QoL during the first weeks after a stroke.

The association between functional independence and quality of life for individuals with acquired brain injury undergoing community-based rehabilitation and disability support

BACKGROUND: Following acquired brain injury (ABI), cognitive and physical barriers can prevent access to a previously enjoyed lifestyle, reducing quality of life. OBJECTIVE: This study aimed to examine predictors of health-related quality of life (HRQoL) in adults with ABI receiving post-acute community-based rehabilitation and disability support services, using tools developed for this population. METHODS: Retrospective cross-sectional design. Main outcome measures were the Quality of Life after Brain Injury Inventory (QOLIBRI) and Functional Independence and Assessment Measure (FIM + FAM) for adults with ABI (n = 67) undergoing post-acute rehabilitation in Western Australia, 2015–2021. RESULTS: Mean QOLIBRI total score (±standard deviation) was 57.2±17.4, indicating impaired HRQoL, with mood disorders likely prevalent. Regression analysis demonstrated no differences in HRQoL between different age groups, sexes or brain injury types. Shorter time since injury and lower total FIM + FAM score significantly predicted poorer HRQoL in the model. CONCLUSION: This population appears vulnerable to psychological illness, although HRQoL is addressed for a minority of clients during routine post-acute care (19%). As improvement in quality of life is a fundamental goal of rehabilitation post-ABI, understanding the relationship between potentially modifiable factors such as functional independence and HRQoL is critical to improve outcomes and provide the best chance at a satisfying life.

Measuring functional outcomes in major trauma: can we do better?

PURPOSE

There is relatively limited large scale, long-term unified evidence to describe how quality of life (QoL) and functional outcomes are affected after polytrauma. The aim of this study is to review validated measures available to assess QoL and functional outcomes and make recommendations on how best to assess patents after major trauma.

METHODS

PubMed and EMBASE databases were interrogated to identify suitable patient-reported outcome measures (PROMs) for use in major trauma, and current practice in their use globally.

RESULTS

Overall, 81 papers met the criteria for inclusion and evaluation. Data from these were synthesised. A full set of validated PROMs tools were identified for patients with polytrauma, as well as critique of current tools available, allowing us to evaluate practice and recommend specific outcome measures for patients following polytrauma, and system changes needed to embed this in routine practice moving forward.

CONCLUSION

To achieve optimal outcomes for patients with polytrauma, we will need to focus on what matters most to them, including their needs (and unmet needs). The use of appropriate PROMs allows evaluation and improvement in the care we can offer. Transformative effects have been noted in cases where they have been used to guide treatment, and if embedded as part of the wider system, it should lead to better overall outcomes. Accordingly, we have made recommendations to this effect. It is time to seize the day, bring these measures even further into our routine practice, and be part of shaping the future.

Effects of the robot-assisted gait training device plus physiotherapy in improving ambulatory functions in subacute stroke patients with hemiplegia: An assessor-blinded, randomized controlled trial

OBJECTIVE

To investigate the effects of the robot-assisted gait training device (RAGTD) plus physiotherapy versus physiotherapy alone, in improving ambulatory functions in subacute stroke patients with hemiplegia.

DESIGN

A prospective, assessor-blinded, randomized controlled trial.

SETTING

Subacute stroke patients with hemiplegia admitted at the Rehabilitation Center.

PARTICIPANTS

Twenty-six subacute stroke patients with hemiplegia.

INTERVENTION

All patients received 30 training sessions (five days/week for six weeks) which included conventional physiotherapy training (60 min) and ambulation training (60 min). In the ambulation training session, the RAGTD group received robotic training (40 min) and ground ambulation training (20 min). The control group received only ground ambulation training (60 min). The outcomes were assessed at the initial session, the end of the 15^th and the 30^th sessions. Comparisons within group and between the groups were conducted.

MAIN OUTCOME MEASURES

Primary outcome variables were the Functional Independence Measure (FIM)-walk score and the efficacy of FIM-walk.

RESULTS

The RAGTD group showed greater improvements from baseline than control in: (1) the FIM-walk score, at the end of the 15^th session (p = 0.012), (2) the efficacy of FIM-walk, at the end of the 15^th session (p = 0.008), (3) walking distance in the 6-minute walk test (6MWT), at the end of the 15^th session (p = 0.018), (4) the Barthel Index for Activities of Daily Living (ADL), at the end of the 30^th session (p < 0.001), and (5) gait symmetry ratio, at the end of the 30^th session (p = 0.044). Other gait parameters showed tendencies of improvement in the RAGTD group, but there were no significant differences.

CONCLUSION

RAGTD plus physiotherapy showed early improvements in walking ability and Barthel ADL index compared to the ground level training plus physiotherapy in subacute stroke patients with hemiplegia.

Functional outcomes and cost-efficiency of specialist in-patient rehabilitation following spinal cord injury: a multi-centre national cohort analysis from the UK Rehabilitation Outcomes Collaborative (UKROC)

Purpose: To evaluate functional outcomes, care needs and cost-efficiency of specialist rehabilitation for a multi-centre cohort of inpatients with spinal cord injury (SCI)-comparison based on age and aetiology.Methods and materials: Retrospective analysis of prospectively collected data from the UK Rehabilitation Outcomes Collaborative (UKROC) national clinical database from 2012-2019. Adults with SCI admitted for a rehabilitation programme in levels 1 and 2 specialist rehabilitation Units in England, were included if they had valid UK Functional Assessment Measure (UK FIM + FAM) and Northwick Park Dependency Scale (NPDS) scores recorded on admission and discharge (n = 2506 of 3321 admissions).Results: Approximately 425 patients were admitted yearly. 1344(56%) patients were under 65. 736(29%) had traumatic aetiology. Older and Traumatic SCI patients were more likely to have cervical cord damage (X², p < 0.001). There was a significant improvement in all parameters of functional independence (UK FIM + FAM) (p < 0.001), with the reduction in dependency and care costs (NPDS/NPCNA) (p < 0.001). 1817(72.5%) patients were discharged home. Mean care-costs savings were £25 500/year per patient. Year-on-year trends showed admissions with increasing age, higher complexity and dependency with corresponding increasing episode costs (ANOVA p < 0.001). However, the time taken to offset the cost of rehabilitation did not change significantly (ANOVA p = 0.57).Conclusions: Specialist rehabilitation services provide effective and cost-efficient rehabilitation for patients with spinal cord injury.Implications for RehabilitationApproximately a third of patients who access specialist inpatient rehabilitation following spinal cord injury (SCI) in England are managed in the Specialist Level 1 and 2 neuro-rehabilitation units, rather than in the eight designated national SCI Centres.Despite admitting progressively more complex and dependent patients over eight years, these specialist rehabilitation units continue to provide highly cost-efficient care.The mean annual savings amount to £25,500 per patient. With a mean admission rate of 425 patients, this would generate total savings in excess of £10 million per year for the cohort.Specialist rehabilitation services play an important, but under-recognised, role in the spinal cord injury care pathway.

Are extracapsular and intracapsular hip-fracture patients two distinct rehabilitation subpopulations?

PURPOSE

To assess whether intracapsular and extracapsular hip fracture patients in a post-acute rehabilitation setting differ in their background characteristics and whether fracture type affects rehabilitation outcome.

METHODS

A retrospective cohort study.

OUTCOME MEASURES

Functional Independence Measure (FIM), motor FIM (mFIM), mFIM effectiveness, length of stay (LOS), and discharge destination. Various tests assessed associations (the Mann-Whitney U, the chi-square, logistic regression), population differences (t-test), and independent predictors of discharge FIM score (multiple linear regression model).

RESULTS

Six hundred and eighty-seven patients completed the rehabilitation program. The intracapsular hip fracture patient group was characterized by significantly higher percentages of males, higher education levels, and living with a caregiver compared with the extracapsular hip fracture patient group. Intracapsular hip fracture patients were younger, had longer latency time from fracture to surgery, exhibited higher functional levels on admission and upon discharge, higher cognitive function and shorter rehabilitation time than extracapsular hip fracture patients. Both study groups possessed similar comorbidities, rehabilitation achievements, and discharge destination. Regression analyses showed that the fracture type was not associated with discharge FIM score, nor with the probability of achieving a favorable functional gain.

CONCLUSIONS

Post-acute extracapsular and intracapsular hip fracture patients are demographically and clinically two distinct subpopulations. Nevertheless, given additional time, extracapsular hip fracture patients will attain similar functional achievements as intracapsular hip fracture patients.Implications for rehabilitationPost-acute extracapsular and intracapsular hip fracture patients are demographically and clinically two distinct subpopulations.Given additional time, extracapsular hip fracture patients can attain similar functional achievements as intracapsular hip fracture patients.

Community Rehabilitation Outcomes for Different Stroke Diagnoses: An Observational Cohort Study

Objective

To determine the differences in functional and cognitive rehabilitation gains made in community-based rehabilitation following a stroke based on stroke diagnosis (left or right hemisphere, hemorrhagic, or ischemic).

Design

A 12-month follow-up observational retrospective cohort study.

Setting

Staged community-based brain injury rehabilitation.

Participants

Clients (N=61) with hemorrhagic left brain stroke (n=10), hemorrhagic right brain stroke (n=8), ischemic left brain stroke (n=27), or ischemic right brain stroke (n=16) participating in rehabilitation for at least 12 months.

Intervention

Not applicable.

Main Outcome Measures

The Mayo-Portland Adaptability Inventory-4 (MPAI-4) was completed at admission and 12 months post admission to staged community-based brain injury rehabilitation by consensus of a multidisciplinary team.

Results

After 12 months in staged community-based brain injury rehabilitation, the study population made significant gains in Total (P<.001) and across Ability (P<.001) and Participation (P<.001) subscales of the MPAI-4. All diagnostic groups made significant gains in Participation T-scores, and no groups made significant gains in Adjustment. The ischemic left and right hemisphere stroke groups also made significant gains in Ability and Total T-scores from admission to 12 months. Clients with ischemic left hemisphere stroke had more severe limitations in motor speech (P<.05) than clients with right hemisphere stroke at admission and/or review and were also more impaired in verbal communication (P<.01) than the hemorrhagic right hemisphere group at admission.

Conclusions

There are some differences in outcomes on presentation to rehabilitation based on type of stroke; there are also differences in rehabilitation gains. Improvement in physical ability does not always translate to improvement in social participation and independence; those with right brain stroke need further assistance to translate physical gains into participatory outcomes.

Estimated Life-Time Savings in the Cost of Ongoing Care Following Specialist Rehabilitation for Severe Traumatic Brain Injury in the United Kingdom

Supplemental Digital Content is Available in the Text.

Objectives:

To evaluate cost-efficiency of rehabilitation following severe traumatic brain injury (TBI) and estimate the life-time savings in costs of care.

Setting/Participants:

TBI patients (n = 3578/6043) admitted to all 75 specialist rehabilitation services in England 2010–2018.

Design:

A multicenter cohort analysis of prospectively collated clinical data from the UK Rehabilitation Outcomes Collaborative national clinical database.

Main Measures:

Primary outcomes: (a) reduction in dependency (UK Functional Assessment Measure), (b) cost-efficiency, measured in time taken to offset rehabilitation costs by savings in costs of ongoing care estimated by the Northwick Park Dependency Scale/Care Needs Assessment (NPDS/NPCNA), and (c) estimated life-time savings.

Results:

The mean age was 49 years (74% males). Including patients who remained in persistent vegetative state on discharge, the mean episode cost of rehabilitation was £42 894 (95% CI: £41 512, £44 235), which was offset within 18.2 months by NPCNA-estimated savings in ongoing care costs. The mean period life expectancy adjusted for TBI severity was 21.6 years, giving mean net life-time savings in care costs of £679 776/patient (95% CI: £635 972, £722 786).

Conclusions:

Specialist rehabilitation proved highly cost-efficient for severely disabled patients with TBI, despite their reduced life-span, potentially generating over £4 billion savings in the cost of ongoing care for this 8-year national cohort.

Factors predicting rehabilitation outcomes after severe acquired brain injury in trauma, stroke and anoxia populations: A cohort study

Severe acquired brain injury has long-term physical and cognitive effects. Identifying patient variables predictive of recovery in different brain injury populations would generate improved prognostic information and help rehabilitation teams set appropriate therapeutic goals. This cohort study of 447 NHS neurorehabilitation inpatients aimed to identify functional and cognitive predictors of recovery following severe acquired brain injury caused by trauma, stroke and anoxia. Motor and cognitive impairment ratings were collected at admission and discharge using the Functional Independence Measure and Functional Assessment Measure (FIM+FAM), and injury-related and demographic data were collated from medical records. Predictors of physical, cognitive and overall recovery were identified via hierarchical regression analyses. Several key findings emerged. Firstly, on-admission motor skills predicted functional and overall outcomes across groups. Secondly, on-admission social interaction skills predicted cognitive discharge outcomes in stroke and trauma, and overall outcomes for stroke, but did not predict anoxia outcomes. Thirdly, age predicted all forms of recovery for stroke only. Further group-specific factors were also identified as predicting motor and cognitive recovery, indicating that factors key to the rehabilitation trajectory may differ between populations. These variables should be considered in rehabilitation goal planning, although further research is required to explore their contributions to recovery.

Following severe childhood stroke, specialised residential rehabilitation improves self-care independence but there are ongoing needs at discharge

Introduction

Stroke is a major cause of mortality and disability in childhood. There is a false belief that children will recover better than adults and recent research confirms that younger age at injury can have a negative impact on rehabilitation outcomes, resulting in lifelong disability. Self-care is a key rehabilitation outcome for children and young people.

Methods

This service evaluation reviews routinely collected clinical self-care data from one specialised residential rehabilitation centre in the United Kingdom. Admission and discharge scores from the United Kingdom Functional Independence Measure +Functional Assessment Measure, Rehabilitation Complexity Scale – E and Northwick Park Nursing Dependency Scale were analysed.

Results

Twenty-six children and young people age 8 years and over with severe stroke were included. Mean scores of independence increased and mean scores of complexity and dependency decreased. A proportion of the sample had ongoing self-care needs in relation to support needed in washing, dressing and bathing. A small number remained highly dependent, requiring assistance from two carers.

Conclusion

Children and young people make significant gains in self-care independence during specialised rehabilitation. However, a proportion return to the community with high self-care needs. Occupational therapists and the wider care team should address ongoing self-care needs in this population.

Patients' Measurement Priorities for Remote Measurement Technologies to Aid Chronic Health Conditions: Qualitative Analysis

Background

Remote measurement technology (RMT), including the use of mobile phone apps and wearable devices, may provide the opportunity for real-world assessment and intervention that will streamline clinical input for years to come. In order to establish the benefits of this approach, we need to operationalize what is expected in terms of a successful measurement. We focused on three clinical long-term conditions where a novel case has been made for the benefits of RMT: major depressive disorder (MDD), multiple sclerosis (MS), and epilepsy.

Objective

The aim of this study was to conduct a consultation exercise on the clinical end point or outcome measurement priorities for RMT studies, drawing on the experiences of people with chronic health conditions.

Methods

A total of 24 participants (16/24 women, 67%), ranging from 28 to 65 years of age, with a diagnosis of one of three chronic health conditions―MDD, MS, or epilepsy―took part in six focus groups. A systematic thematic analysis was used to extract themes and subthemes of clinical end point or measurement priorities.

Results

The views of people with MDD, epilepsy, and MS differed. Each group highlighted unique measurements of importance, relevant to their specific needs. Although there was agreement that remote measurement could be useful for tracking symptoms of illness, some symptoms were specific to the individual groups. Measuring signs of wellness was discussed more by people with MDD than by people with MS and epilepsy. However, overlap did emerge when considering contextual factors, such as life events and availability of support (MDD and epilepsy) as well as ways of coping (epilepsy and MS).

Conclusions

This is a unique study that puts patients’ views at the forefront of the design of a clinical study employing novel digital resources. In all cases, measuring symptom severity is key; people want to know when their health is getting worse. Second, symptom severity needs to be placed into context. A holistic approach that, in some cases, considers signs of wellness as well as illness, should be the aim of studies employing RMT to understand the health of people with chronic conditions.

Time between acquired brain injury and admission to community-based rehabilitation: differences in cognitive and functional gains

OBJECTIVE

To determine differences in rehabilitation gains made by people with an acquired brain injury undergoing staged community-based brain injury rehabilitation (SCBIR) at different times between injury and admission.

METHOD

Retrospective cohort analysis of routinely collected demographic and rehabilitation data from clients admitted to SCBIR service 2011-2017 (n=92). Outcome measures: Mayo-Portland Adaptability Inventory-4 (MPAI-4) and UK Functional Assessment Measure (UK FIM+FAM) collected on admission and annually thereafter until discharge. Analysis was stratified by time since injury on admission: 'Early' (<1 year (n=36)), 'Middle' (1-2 years (n=34)) and 'Late' (>2 years (n=22)). Between-group differences were tested using bootstrapped one-way ANOVA. Within-group differences were tested using paired T tests.

RESULTS

Total cohort made significant gains in MPAI-4 and UK FIM+FAM total and all subscales (p = .001). Early group made greatest change in all subscales of both outcome measures (p < .01). Middle cohort improved significantly in all subscales (p < .02) excluding MPAI-4 Adjustment. Late cohort still made statistically significant gains in all UK FIM+FAM subscales (p < .05) and MPAI-4 Participation (p < .01). Item level changes are presented.

CONCLUSION

More than 2 years after injury, people are able to make improvements in participation and functional independence following SCBIR.

Measurement of mobility and physical function in hospitalised trauma patients: A systematic review of instruments and their measurement properties

Introduction

It is well recognised that organised trauma systems reduce trauma patient mortality. As established systems mature, there is an increasing need to better understand the patient recovery trajectory. Mobility and physical function are key aspects of recovery, but the optimal instruments for measurement in the acute hospital setting remain unclear.

Methods

A systematic review was undertaken to identify and describe mobility and physical function instruments scored by direct patient assessment, in adult trauma patients in an acute hospital setting. Databases were searched with no date restrictions. Instruments that were specific to subgroups or related to individual conditions, diseases or joints were excluded. The consensus-based standards for the selection of health measurement instruments checklist was used to assess risk of bias where relevant. Clinimetric properties were reported where possible, including reliability, validity and responsiveness.

Results

Fourteen thousand one hundred and fourteen articles were identified with 37 eligible for final review, including six instruments. None had been specifically designed for use in a heterogeneous range of trauma patients. The Functional Independence Measure was the most commonly cited (n = 10 studies), with evidence of construct validity, responsiveness and minimal floor/ceiling effects (<3%). The Acute Care Index of Function (n = 1 study) was found to be valid and responsive whilst the modified Iowa Level of Assistance (n = 2 studies) was reliable and responsive, but ceiling effects ranged from 26% to 37%. Little clinimetric data were available for other measures.

Conclusion

Evidence from a few studies show promise for the use of the Functional Independence Measure, Acute Care Index of Function and modified Iowa Level of Assistance to measure mobility and physical function in trauma patients, however comprehensive clinimetric data are lacking. Future research should test these scores in specifically designed clinimetric property studies in defined trauma patient populations. This would enable the identification of a gold standard measure for evaluating treatment effectiveness, enabling benchmarking between centres, allow prediction of recovery pathways and optimise trauma patient outcomes.

Cost-efficiency of specialist inpatient rehabilitation for adults with multiple sclerosis: A multicentre prospective cohort analysis of the UK Rehabilitation Outcomes Collaborative national clinical dataset for rehabilitation centres in England

Background

Rehabilitation is effective for multiple sclerosis, but is it value for money?

Objectives

To evaluate functional outcomes, care needs and cost-efficiency of specialist inpatient rehabilitation for adults with multiple sclerosis (MS).

Methods

A multicentre cohort study of prospectively collected clinical data from the UK Rehabilitation Outcomes Collaborative national clinical database. Data included all adults with MS (n = 1007) admitted for specialist inpatient (Level 1 or 2) rehabilitation in England, 2010–2018.

Outcome measures

Dependency/care needs: Northwick Park Dependency Scale/Care Needs Assessment, Functional independence: UK Functional Assessment Measure (UK FIM+FAM). Cost-efficiency. Patients were analysed in three dependency groups (High/Medium/Low).

Results

All groups showed significant reduction in dependency between admission and discharge on all measures (paired t-tests: p < 0.001). Mean reduction in care costs/week was greatest in the most dependent patients: High: £519 (95% CI: 447–597), Medium: £148 (76–217), Low: £36 (12–83). Despite longer stays, time taken to offset the cost of rehabilitation was shortest in the most dependent patients: High: 12.9 (12.0–14.1) months; Medium: 29.3 (21.3–51.8); Low: 76.8 (0–36.1). Item-level changes corresponded with clinical experience.

Conclusions

Specialist rehabilitation provided good value for money in patients with MS, yielding improved outcomes and substantial savings in ongoing care costs, especially in high-dependency patients.

Outcomes for older adults in inpatient specialist neurorehabilitation

BACKGROUND

Inpatient specialist neurorehabilitation in the United Kingdom is based on providing a service to "working-age" adults (<65 years), with little evidence for outcomes for older adults involved with these services.

OBJECTIVE

The aim of this study is to determine any difference in outcome after inpatient neurorehabilitation between younger and older adults assessed as having rehabilitation potential.

METHODS

A two-centre retrospective review was performed comparing patients aged<65 and≥65 years by diagnostic group in terms of length of stay, changes in UK Functional Independence Measure+Functional Assessment Measure (UK FIM+FAM) scores and discharge destination.

RESULTS

Six hundred and sixteen patients (32%≥65 years) were included. The 2 age groups did not differ in length of stay (median difference 7 days, 95% confidence interval [CI] -2 to 15, P=0.112), but both UK FIM+FAM change and efficiency were higher for the older than younger group (median difference 7, 95% CI 2-13, P=0.006 and 0.10, 0.01-0.19, P=0.031 respectively). Older age was associated with discharge to long-term care (6%<65 years; 11%≥65 years, x²=4.10, P=0.043). Results and trends were similar in patients with acquired brain injury (n=429), spinal cord injury (n=59) and peripheral neuropathy (n=34) but not progressive neurological disorders (n=70).

CONCLUSION

Older adults considered to have rehabilitation potential may have greater functional gains from inpatient specialist inpatient rehabilitation than younger adults. Age alone should not exclude admission to inpatient specialist neurorehabilitation.

Overview of reviews of standardised occupation-based instruments for use in occupational therapy practice

INTRODUCTION

Using standardised instruments is one approach to support evidence-based practice. Referring to systematic reviews is an option to identify suitable instruments. However, with an abundance of systematic reviews available, therapists are challenged to identify an appropriate instrument to use. Therefore, this overview of reviews aimed to summarise relevant systematic review findings about standardised occupation-based instruments relevant for occupational therapy practice.

METHODS

An overview of reviews was conducted. A systematic search was performed on four databases up to March 2018. Included systematic reviews were analysed for quality using A MeaSurement Tool to Assess systematic Reviews (AMSTAR).

RESULTS

A total of 2187 articles were identified after removing duplicates. Ultimately, 58 systematic reviews were identified that yielded 641 instruments. From those, 45 instruments were selected for appraisal as they met the inclusion criteria of being developed mainly by occupational therapists and were recommended in the summarised findings from the systematic reviews. The instruments were classified according to the following occupation domains: (i) multidimensional, (ii) activities of daily living, (iii) productivity, (iv) social, (v) sleep/rest, (vi) sexuality and (vii) spirituality. No systematic review was identified that specifically focussed on occupations related to school/education, leisure and play.

DISCUSSION

Certain occupation domains such as activities of daily living, social and sleep/rest received high attention amongst researchers. There is a need for systematic reviews of instruments to measure education/school, play and leisure. Limited numbers of instruments were developed by occupational therapists outside the occupation domain of activities of daily living, and in areas of practice other than children and older people. Nevertheless, this overview can give some guidance for occupational therapists in selecting a suitable occupational therapy instrument for practice.

A comparison of patients managed in specialist versus non-specialist inpatient rehabilitation units in Australia

Aim: To compare the rehabilitation of patients with brain and spinal cord injury in specialist rehabilitation units and non-specialist rehabilitation units in Australia over a 10-year period.Method: A retrospective cohort study design was used. Epidemiological descriptive analysis was used to examine inpatient rehabilitation data held in the Australasian Rehabilitation Outcomes Centre Registry Database at four discrete time points: 2007, 2010, 2013 and 2016. Data sets included patient demographics, length of stay and the Functional Independence Measure. Data sets were examined for differences between specialist and non-specialist rehabilitation units.Results: Over the 10-year study period, compared to patients admitted to non-specialist rehabilitation units patients admitted to specialist rehabilitation units: (1) were younger and more likely to be male; (2) had a longer time between onset of illness/injury and rehabilitation admission; (3) had a longer median rehabilitation length of stay; (4) had a higher burden of care on admission to rehabilitation; however (5) had a greater functional gain. Patients in specialist rehabilitation units had a lower relative functional efficiency per day of rehabilitation, but higher percentage of Functional Independence Measure gain. In 2016, 66% of brain injury and 51% of spinal cord injury patients were not rehabilitated in specialist rehabilitation units.Conclusion: There are differences in the characteristics of patients admitted to specialist versus non-specialist rehabilitation units. Patients admitted to specialist rehabilitation units have greater functional gain. A noteworthy proportion of brain and spinal cord injury patients are not being rehabilitated in specialist rehabilitation units, particularly patients with non-traumatic injuries.Implications for rehabilitationPatients with a brain or spinal cord injury rehabilitated in specialist rehabilitation units achieve a greater functional gain than those in non-specialist units.Development of best practice admission guidelines would better enable the right care for the right patient in the right setting at the right time.There is a need for longitudinal examination of patient outcomes to better understand the long-term benefits of being rehabilitated in specialist rehabilitation units compared to non-specialist rehabilitation units.

Converting Functional Autonomy Measurement System Scores of Patients Post-Stroke to FIM Scores

Purpose: The Functional Independence Measure (FIM) is widely used to assess persons post-stroke. The Quebec government has selected the Functional Autonomy Measurement System (SMAF) for use in all care settings. In this article, we propose simple equations to convert SMAF scores to FIM scores for persons undergoing post-stroke rehabilitation. Method: Persons post-stroke (n=143) from three rehabilitation centres were assessed at admission and discharge using the FIM and SMAF. The sample was randomly split into derivation and validation data sets. Regression analysis was performed on the first data set to derive a conversion equation at each time point. The validity of the equations was measured using correlation coefficients, and differences between the observed and predicted FIM scores were computed from the second data set. Results: The relationship between the SMAF and FIM scores was linear at admission but quadratic at discharge. The proposed equations are, at admission, FIM=139-1.5×SMAF and, at discharge, FIM=118-0.018×SMAF². The observed and predicted FIM scores were highly correlated in the validation data set (rs=0.92 and 0.93 at admission and discharge, respectively). Furthermore, the equations performed well in classifying stroke severity compared with a classification based on the observed FIM scores. Conclusions: SMAF scores can be reliably converted to FIM scores using the proposed equations, thus facilitating international trials in stroke rehabilitation.

Evaluating the Functional and Cognitive Examination for patients with acute acquired brain injury

Background/Aims:

The Functional and Cognitive Examination is a cross-battery neuropsychological baseline assessment. It was designed specifically for patients with acquired brain injury in the acute rehabilitation stage. This investigation focused on the utility of the Functional and Cognitive Examination to identify the association between the functional and cognitive performance of acquired brain injury patients and the construct validity of the battery.

Methods:

The Functional and Cognitive Examination is administered as a standard for all patients admitted to the inpatient neurological assessment and specialist rehabilitation unit. Forty two patients had been recruited over a two year period. Raw scores have been analysed and descriptive data is provided. Spearman's correlations were used to observe associations between functional and cognitive performance. The Functional and Cognitive Examination was also correlated against the Functional Assessment Measure and the Northwick Park Therapy Dependency Assessment.

Findings:

There was a positive association between lower performance on the Functional and Cognitive Examination cognitive component and the Functional and Cognitive Examination functional task. Similarly, lower scores on the Functional Assessment Measure had positive associations with performance on the Functional and Cognitive Examination functional task.

Conclusions:

The Functional and Cognitive Examination is a useful neuropsychological baseline assessment. It illustrates that cognitive and functional components are associated and the Functional and Cognitive Examination outcomes are associated with the Functional Assessment Measure.

Identifying Unmet Rehabilitation Needs in Patients After Stroke With a Graphic Rehab-CompassTM

BACKGROUND

Unmet rehabilitation needs are common among stroke survivors. We aimed to evaluate whether a comprehensive graphic "Rehab-Compass," a novel combination of structured patient-reported outcome measures, was feasible and useful in facilitating a capture of patients' rehabilitation needs in clinical practice.

METHODS

A new graphic overview of broad unmet rehabilitation needs covers deficits in functioning, daily activity, participation, and quality of life. It was constructed by using 5 patient-oriented, well-validated, and reliable existing instruments with converted data into a 0 (worst outcome) to 100 (best outcome) scale but unchanged in terms of variable properties. Satisfaction of the Rehab-Compass^TM was studied by a qualitative interview of 9 patients with stroke and 3 clinicians. Practical feasibility and capacity of the instrument were evaluated in a cross-sectionalstudy with 48 patients at 5-month follow-ups after subarachnoid hemorrhage.

RESULTS

The Rehab-Compass^TM identified and graphically visualized a panoramic view of the multidimensional needs over time which was completed before clinical consultation. The Rehab-Compass^TM appeared to be feasible and time-efficientin clinical use. The interviews of both patients and clinicians showed high satisfaction when using the Rehab-Compass^TM graph. In the studied stroke patients, the Rehab-Compass^TM identified memory and processing information, fatigue, mood, and pain after subarachnoid hemorrhage as the most common problems.

CONCLUSIONS

The graphic Rehab-Compass^TM seems to be a feasible, useful, and time-saving tool for identification of unmet rehabilitation needs among stroke survivors in clinical practice. Further research is needed to make the Rehab-Compass^TM more concise and evaluate the instrument among different stroke subgroups.

Pain in Maintenance Hemodialysis Patients: A Multicenter Study

CONTEXT

Pain is a common complaint in maintenance hemodialysis (MHD) patients yet is often inadequately assessed and undertreated.

OBJECTIVES

The objective of this study was to evaluate the prevalence, characteristics, intensity, and impact of pain in MHD patients.

METHODS

In a cross-sectional study conducted between 2013 and 2015, 336 MHD patients from five hemodialysis units in hospitals owned by Clalit were interviewed and evaluated. Study tools included the Brief Pain Inventory, The Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale, and demographic and clinical characteristics. In addition, computerized pharmaceutical data were reviewed.

RESULTS

Pain was experienced by 82% of the study population (mean pain level: 7.2 ± 2.2) in the 24-hour period before the interview, while 61.5% experienced neuropathic pain characteristics. Of patients with pain, two-thirds reported being regularly treated with pain medications, while 24.5% received nondrug pain treatment. Mean pain relief due to Brief Pain Inventory was 62.5 ± 30%. In multivariate analysis, female gender, a high comorbidity index, and time on dialysis >24 months were associated with the presence of significant pain in the previous 24 hours. In addition, severe pain report was associated with female gender, depression, ≥4 painful sites, and unemployment. Finally, neuropathic pain was associated with time on dialysis >24 months, depression, ≥4 painful sites, and current intensity of pain >2.

CONCLUSION

Pain is common in MHD patients and is significantly associated with female gender, comorbidity, time on dialysis, and depression. Results of this study may serve as a starting point for palliative interventions for MHD patients.

Brain injury rehabilitation after road trauma in new South Wales, Australia - insights from a data linkage study

Background

Population-based patterns of care studies are important for trauma care but conducting them is expensive and resource-intensive. Linkage of routinely collected administrative health data may provide an efficient alternative. The aims of this study are to describe the rehabilitation pathway for trauma survivors and to analyse the brain injury rehabilitation outcomes in the two care settings (specialist brain injury and non-specialist general rehabilitation units).

Methods

This is an observational study using routinely collected registry data (New South Wales Trauma Registry linked with the Australasian Rehabilitation Outcomes Centre Inpatient Dataset). The study cohort includes 268 road trauma patients who were admitted to trauma services between 2009 and 2012 and received inpatient rehabilitation because of a brain injury.

Results

Of those who need inpatient rehabilitation, 62% (n = 166) were admitted to specialist units with the remainder (n = 102) admitted to non-specialist units. Those admitted to a specialist units were younger (p < 0.001), had a lower cognitive FIM score (p = 0.003) on admission than those admitted to non-specialist units. Specialist units achieved better overall FIM score improvements from admission to discharge (43 vs 30 points, p > 0.001) but at a cost of longer length of stay (median 47 vs 24 days, p < 0.001). There were very few discharges to residential aged care facilities from rehabilitation (2% in non-specialist units and none from specialist units). There was a long time lag between trauma and admission to inpatient rehabilitation with only a quarter of the patients admitted to a specialist unit by end of week four. Few older patients (19%) with brain injury were admitted to specialist units.

Conclusions

It is feasible to use routinely collected registry data to monitor inpatient rehabilitation outcomes of trauma care. There were differences in characteristics and outcomes of patients with traumatic brain injury admitted to specialist units compared with non-specialist units.

The patient categorisation tool: psychometric evaluation of a tool to measure complexity of needs for rehabilitation in a large multicentre dataset from the United Kingdom

PURPOSE

This first psychometric evaluation of the Patient Categorisation Tool examined its properties as an instrument to measure complexity of needs in a mixed population of patients presenting for specialist neurorehabilitation.

MATERIALS/METHODS

Analysis of a large multicentre cohort of patients (n = 5396) from the national clinical dataset representing 63 specialist rehabilitation services across England. Structural validity was examined using exploratory and confirmatory factor analysis. Concurrent and criterion-validity were tested through a priori hypothesized relationships with other validated measures of resource requirements and dependency.

RESULTS

All but two items loaded strongly onto a single principal component with Cronbach's alpha 0.88. A total score of ≥30 identified patients with complex (category A) needs with sensitivity 76% and specificity 75%. However, confirmatory factor analysis provided a better fit when the scale was split into two subscales - a 'Cognitive/psychosocial' and a 'Physical' sub-scale (alpha 0.83 and 0.84, respectively). Moderate convergent and discriminant correlations were consistent with hypothesized relationships.

CONCLUSIONS

The findings provide some overall support for the Patient Categorisation Tool as a unidimensional tool for measuring complexity of needs for neurorehabilitation, but the subscales may be more suitable for certain groups of patients. Further analysis is now required to evaluate its performance in different conditions. Implications for Rehabilitation A psychometrically robust tool for measuring the complexity of rehabilitation needs has potential value, both at an individual level for treatment planning, and at a population level for planning and commissioning rehabilitation services. The Patient Categorisation Tool now forms part of the United Kingdom national clinical dataset mandated by the National Health Service in England This psychometric analysis from a large national multicentre cohort representing a diverse range of conditions, provides evidence for its validity as a means to identity patients with complex rehabilitation needs requiring specialist rehabilitation.

Measuring changes in functional ability in older children and young people with acquired brain injury using the UK FIM + FAM

Introduction

There is a need for validated and responsive measurement tools to demonstrate changes in functional ability. Existing outcome measurement tools have significant limitations for children and young people with acquired brain injury (ABI).

Aim

This study examines the potential of the UK Functional Independence Measure + Functional Assessment Measure (UK FIM + FAM) to detect clinical change in older children and young people with ABI.

Method

This is a secondary retrospective pretest–post test analysis of 72 children and young people age 8–17 years. Internal responsiveness was examined using Wilcoxon signed-rank tests and effect sizes indices; external responsiveness was examined in relation to the Neurological Impairment Scale (NIS) using Spearman’s correlation coefficient.

Results

Highly significant changes were detected from admission to discharge on motor, cognitive and total UK FIM + FAM scores ( p < 0.001). Medium to large effect sizes were found on the total scale indicating good internal responsiveness. There was a significant, negative correlation between UK FIM + FAM change scores and NIS change scores ( p < 0.01) indicating good external responsiveness.

Conclusion

The UK FIM + FAM was able to detect clinically meaningful change in functional ability in children and young people with ABI over 8 years. Further validity and reliability must be established before recommending its use in this client group.

The Responsiveness of the Lucerne ICF-Based Multidisciplinary Observation Scale: A Comparison with the Functional Independence Measure and the Barthel Index

Background

Good responsive functional outcome measures are important to measure change in stroke patients. The aim of study was to compare the internal and external responsiveness, floor and ceiling effects of the motor, cognition, and communication subscales of the Lucerne ICF-based Multidisciplinary Observation Scale (LIMOS) with the motor and cognition subscales of the Functional Independence Measure (FIM), and the Barthel Index (BI), in a large cohort of stroke patients.

Methods

One hundred eighteen stroke patients participated in this study. Admission and discharge score distributions of the LIMOS motor, LIMOS cognition and communication, FIM motor and FIM cognition, and BI were analyzed based on skewness and kurtosis. Floor and ceiling effects of the scales were determined. Internal responsiveness was assessed with t-tests, effect sizes (ESs), and standardized response means (SRMs). External responsiveness was investigated with linear regression analyses.

Results

The LIMOS motor and LIMOS cognition and communication subscales were more responsive, expressed by higher ESs (ES = 0.65, SRM = 1.17 and ES = 0.52, SRM = 1.17, respectively) as compared with FIM motor (ES = 0.54, SRM = 0.96) and FIM cognition (ES = 0.41, SRM = 0.88) and the BI (ES = 0.41, SRM = 0.65). The LIMOS subscales showed neither floor nor ceiling effects at admission and discharge (all <15%). In contrast, ceiling effects were found for the FIM motor (16%), FIM cognition (15%) at discharge and the BI at admission (22%) and discharge (43%). LIMOS motor and LIMOS cognition and communication subscales significantly correlated (p < 0.0001) with a change in the FIM motor and FIM cognition subscales, suggesting good external responsiveness.

Conclusion

We found that the LIMOS motor and LIMOS cognition and communication, which are ICF-based multidisciplinary standardized observation scales, might have the potential to better detect changes in functional outcome of stroke patients, compared with the FIM motor and FIM cognition and the BI.

Cost-efficiency of specialist hyperacute in-patient rehabilitation services for medically unstable patients with complex rehabilitation needs: a prospective cohort analysis

OBJECTIVES

To evaluate functional outcomes, care needs and cost-efficiency of hyperacute (HA) rehabilitation for a cohort of in-patients with complex neurological disability and unstable medical/surgical conditions.

DESIGN

A multicentre cohort analysis of prospectively collected clinical data from the UK Rehabilitation Outcomes Collaborative (UKROC) national clinical database, 2012-2015.

SETTING

Two HA specialist rehabilitation services in England, providing different service models for HA rehabilitation.

PARTICIPANTS

All patients admitted to each of the units with an admission rehabilitation complexity M score of ≥3 (N=190; mean age 46 (SD16) years; males:females 63:37%). Diagnoses were acquired brain injury (n=166; 87%), spinal cord injury (n=9; 5%), peripheral neurological conditions (n=9; 5%) and other (n=6; 3%).

INTERVENTION

Specialist in-patient multidisciplinary rehabilitation combined with management and stabilisation of intercurrent medical and surgical problems.

OUTCOME MEASURES

Rehabilitation complexity and medical acuity: Rehabilitation Complexity Scale-version 13. Dependency and care costs: Northwick Park Dependency Scale/Care Needs Assessment (NPDS/NPCNA). Functional independence: UK Functional Assessment Measure (UK FIM+FAM).

PRIMARY OUTCOMES

(1) reduction in dependency and (2) cost-efficiency, measured as the time taken to offset rehabilitation costs by savings in NPCNA-estimated costs of on-going care in the community.

RESULTS

The mean length of stay was 103 (SD66) days. Some differences were observed between the two units, which were in keeping with the different service models. However, both units showed a significant reduction in dependency and acuity between admission and discharge on all measures (Wilcoxon: p<0.001). For the 180 (95%) patients with complete NPCNA data, the mean episode cost was £77 119 (bootstrapped 95% CI £70 614 to £83 894) and the mean reduction in 'weekly care costs' was £462/week (95% CI 349 to 582). The mean time to offset the cost of rehabilitation was 27.6 months (95% CI 13.2 to 43.8).

CONCLUSIONS

Despite its relatively high initial cost, specialist HA rehabilitation can be highly cost-efficient, producing substantial savings in on-going care costs, and relieving pressure in the acute care services.

Measurement of Function Post Hip Fracture: Testing a Comprehensive Measurement Model of Physical Function

BACKGROUND

Measurement of physical function post hip fracture has been conceptualized using multiple different measures.

PURPOSE

This study tested a comprehensive measurement model of physical function.

DESIGN

This was a descriptive secondary data analysis including 168 men and 171 women post hip fracture.

METHODS

Using structural equation modeling, a measurement model of physical function which included grip strength, activities of daily living, instrumental activities of daily living, and performance was tested for fit at 2 and 12 months post hip fracture, and among male and female participants. Validity of the measurement model of physical function was evaluated based on how well the model explained physical activity, exercise, and social activities post hip fracture.

FINDINGS

The measurement model of physical function fit the data. The amount of variance the model or individual factors of the model explained varied depending on the activity.

CONCLUSION

Decisions about the ideal way in which to measure physical function should be based on outcomes considered and participants.

CLINICAL RELEVANCE

The measurement model of physical function is a reliable and valid method to comprehensively measure physical function across the hip fracture recovery trajectory.

Cost-efficiency of specialist inpatient rehabilitation for working-aged adults with complex neurological disabilities: a multicentre cohort analysis of a national clinical data set

OBJECTIVES

To evaluate functional outcomes, care needs and cost-efficiency of specialist rehabilitation for a multicentre cohort of inpatients with complex neurological disability, comparing different diagnostic groups across 3 levels of dependency.

DESIGN

A multicentre cohort analysis of prospectively collected clinical data from the UK Rehabilitation Outcomes Collaborative (UKROC) national clinical database, 2010-2015.

SETTING

All 62 specialist (levels 1 and 2) rehabilitation services in England.

PARTICIPANTS

Working-aged adults (16-65 years) with complex neurological disability.

INCLUSION CRITERIA

all episodes with length of stay (LOS) 8-400 days and complete outcome measures recorded on admission and discharge. Total N=5739: acquired brain injury n=4182 (73%); spinal cord injury n=506 (9%); peripheral neurological conditions n=282 (5%); progressive conditions n=769 (13%).

INTERVENTION

Specialist inpatient multidisciplinary rehabilitation.

OUTCOME MEASURES

Dependency and care costs: Northwick Park Dependency Scale/Care Needs Assessment (NPDS/NPCNA). Functional independence: UK Functional Assessment Measure (UK Functional Independence Measure (FIM)+FAM). Cost-efficiency: (1) time taken to offset rehabilitation costs by savings in NPCNA-estimated costs of ongoing care, (2) FIM efficiency (FIM gain/LOS days), (3) FIM+FAM efficiency (FIM+FAM gain/LOS days). Patients were analysed in 3 groups of dependency.

RESULTS

Mean LOS 90.1 (SD 66) days. All groups showed significant reduction in dependency between admission and discharge on all measures (paired t tests: p<0.001). Mean reduction in 'weekly care costs' was greatest in the high-dependency group at £760/week (95% CI 726 to 794)), compared with the medium-dependency (£408/week (95% CI 370 to 445)), and low-dependency (£130/week (95% CI 82 to 178)), groups. Despite longer LOS, time taken to offset the cost of rehabilitation was 14.2 (95% CI 9.9 to 18.8) months in the high-dependency group, compared with 22.3 (95% CI 16.9 to 29.2) months (medium dependency), and 27.7 (95% CI 15.9 to 39.7) months (low dependency). FIM efficiency appeared greatest in medium-dependency patients (0.54), compared with the low-dependency (0.37) and high-dependency (0.38) groups. Broadly similar patterns were seen across all 4 diagnostic groups.

CONCLUSIONS

Specialist rehabilitation can be highly cost-efficient for all neurological conditions, producing substantial savings in ongoing care costs, especially in high-dependency patients.

Using reliability of change analysis to evaluate post-acute neuro-rehabilitation

BACKGROUND

It is important to evaluate change in order to re-assure commissioners, staff and patients of the effectiveness of interventions, but also in order to identify areas for improvement.

OBJECTIVE

To consider whether analysis of improvement at the level of the individual, taking into account measurement error, may offer a further valuable way to assess change and inform service development over considering change at the group level in a post-acute neuro-rehabilitation unit.

METHOD

Pre and post intervention Scores on the FIM+FAM Full Scale and Cognitive and Motor subscales were considered for eighteen patients aged between 35 and 81 with mixed diagnoses who attended a post-acute inpatient neuro-rehabilitation unit for treatment.

RESULTS

Statistically significant improvements were achieved on the FIM+FAM Full Scale and Cognitive and Motor subscales in a whole group analysis. Reliable change analyses for each patient within each subscale however identified only half of the sample achieved reliable improvement within the Motor domain and just one person within the Cognitive domain (5.6%).

CONCLUSIONS

Findings are consistent with the emphasis of the rehabilitation unit on physical/motor function, and unsurprising as many of those assessed had multiple sclerosis, an often deteriorative condition. Use of reliable change analysis allowed a more detailed understanding of intervention impact, potentially identifying what services reliably work for whom, thereby informing future planning.

The UK Functional Assessment Measure (UK FIM+FAM): Psychometric Evaluation in Patients Undergoing Specialist Rehabilitation following a Stroke from the National UK Clinical Dataset

The UK Functional Assessment Measure (UKFIM+FAM) is the principal outcome measure for the UK Rehabilitation Outcomes Collaborative (UKROC) national database for specialist rehabilitation. Previously validated in a mixed neurorehabilitation cohort, this study is the first to explore its psychometric properties in a stroke population, and compare left and right hemispheric strokes (LHS vs RHS). We analysed in-patient episode data from 62 specialist rehabilitation units collated through the UKROC database 2010-2013. Complete data were analysed for 1,539 stroke patients (LHS: 588, RHS: 566 with clear localisation). For factor analysis, admission and discharge data were pooled and randomised into two equivalent samples; the first for exploratory factor analysis (EFA) using principal components analysis, and the second for confirmatory factor analysis (CFA). Responsiveness for each subject (change from admission to discharge) was examined using paired t-tests and differences between LHS and RHS for the entire group were examined using non-paired t-tests. EFA showed a strong general factor accounting for >48% of the total variance. A three-factor solution comprising motor, communication and psychosocial subscales, accounting for >69% total variance, provided acceptable fit statistics on CFA (Root Mean Square Error of Approximation was 0.08 and Comparative Fit Index/ Tucker Lewis Index 0.922/0.907). All three subscales showed significant improvement between admission and discharge (p<0.001) with moderate effect sizes (>0.5). Total scores between LHS and RHS were not significantly different. However, LHS showed significantly higher motor scores (Mean 5.7, 95%CI 2.7, 8.6 p<0.001), while LHS had significantly lower cognitive scores, primarily in the communication domain (-6.8 95%CI -7.7, -5.8 p<0.001). To conclude, the UK FIM+FAM has a three-factor structure in stroke, similar to the general neurorehabilitation population. It is responsive to change during in-patient rehabilitation, and distinguishes between LHS and RHS. This tool extends stroke outcome measurement beyond physical disability to include cognitive, communication and psychosocial function.

The Northwick Park Therapy Dependency Assessment scale: a psychometric analysis from a large multicentre neurorehabilitation dataset

Purpose: To assess the internal reliability, construct and concurrent validity and responsiveness of the Northwick Park Therapy Dependency Assessment (NPTDA) scale. Method: A cohort of 2505 neurorehabilitation patients submitted to the UK Rehabilitation Outcomes Collaborative database. Cronbach’s coefficient-α was used to assess internal reliability and factor analysis (FA) to assess construct validity. We compared NPTDA scores at admission and discharge to determine responsiveness. Results: Coefficient-α for the whole scale was 0.74. The exploratory FA resulted in a four-factor model (Physical, Psychosocial, Discharge planning and Activities) that accounted for 43% of variance. This model was further supported by the confirmatory FA. The final model had a good fit: root-mean-square error of approximation of 0.069, comparative fit index/Tucker–Lewis index of 0.739/0.701 and the goodness of fit index of 0.909. The NPTDA scores at admission and discharge were significantly different for each of the factors. Expected correlations were seen between the admission scores for the NPTDA, the Rehabilitation Complexity Scale (r = 0.30, p < 0.01) and the Functional Independence Measure (r = −0.25, p < 0.01). Conclusions: The scale demonstrated acceptable internal reliability and good construct and concurrent validity. NPTDA may be used to describe and quantify changes in therapy inputs in the course of a rehabilitation programme.

Implications for Rehabilitation

The Northwick Park Therapy Dependency Assessment (NPTDA) is designed as a measure therapy intervention, which reflects both quantitative and qualitative aspects of the inputs provided (including staff time and the different types of intervention) during inpatient rehabilitation.

The scale demonstrated acceptable internal reliability and good construct and concurrent validity.

NPTDA is responsive to change in the therapy inputs provided during neurorehabilitation between admission and discharge.
