Content comparison of health-related quality of life measures used in stroke based on the international classification of functioning, disability and health (ICF): a systematic review

Content comparison of utility and effectiveness instruments to the Prosthetic Interventions Core Outcome Set: a step to inform the benefits measured in lower-limb prosthetic health economic evaluations

PURPOSE

Health Economic Evaluations (HEEs) calculate a cost-benefit ratio using utility and effectiveness instruments. It is unknown whether existing instruments measure the items of the Prosthetic Interventions Core Outcome Set (PI-COS) that represent the benefits most important to lower-limb prosthesis users and funders. Comparing the content of existing instruments against the PI-COS will support instrument selection for future prosthetic HEEs.

MATERIALS AND METHODS

Utility and effectiveness instruments used to evaluate prosthetic interventions were identified and their International Classification of Functioning, Disability and Health framework (ICF) linking results were extracted. Content of each instrument was compared to the PI-COS through three metrics: content density, content diversity and bandwidth.

RESULTS

Of the 130 utility and effectiveness instruments, 24 had previously been linked to the ICF. The instrument with the greatest bandwidth (i.e., broadest content coverage of the PI-COS) was the SF-36 given it linked to 6 of the 14 items of the PI-COS. Combining PROMIS subscales and short-forms allow measurement of a greater range of the PI-COS items.

CONCLUSIONS

There is no perfect fit instrument providing coverage of the PI-COS using the metrics of content density, content diversity and bandwidth. The PROMIS instrument may provide increase coverage of the PI-COS in future HEEs.

How well do we measure the impact of bowel dysfunction on health-related quality of life after rectal cancer surgery?

BACKGROUND

Rectal cancer surgery risks causing bowel dysfunction, which has an important impact on health-related quality of life. The validity of generic tools used to measure health-related quality of life after bowel dysfunction is unclear. This study aimed to determine the content validity of health-related quality-of-life measurement tools in rectal cancer.

METHODS

This was a qualitative single-center study in which adult patients who underwent rectal cancer surgery with sphincter preservation from July 2017 to October 2020 were recruited. Patients were excluded if they developed local metastasis, required a permanent stoma, or had surgery <1 year since recruitment. Telephone-based semi-structured interviews were conducted. Bowel dysfunction was measured using the Low Anterior Resection Syndrome score. Content analysis was achieved using the International Classification of Functioning framework.

RESULTS

Recurrent bowel dysfunction-related concepts included "Mental functions," "Defecation functions," "Emotional functions," "Recreation and leisure," "Intimate relationships," and "Remunerative employment." A mean of 7.5 recurrent bowel dysfunction-related concepts were identified within the health-related quality of life instruments analyzed. The European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire-C30 (n = 11) and the 36-Item Short Form Health Survey (n = 9) covered the greatest number of recurrent bowel dysfunction-related concepts. Concepts such as "Mental functions," "Urination functions," "Sexual functions," "Driving," and "Mobility" were not covered by any instrument.

CONCLUSION

The content of traditional health-related quality-of-life instruments is missing important areas that represent the impact of bowel dysfunction after rectal cancer surgery on health-related quality of life. These findings could help improve patient-centered care in rectal cancer surgery.

Assessing the Adequacy of the Physical, Social, and Attitudinal Environment to the Specific Needs of Young Adults With Cerebral Palsy: The European Adult Environment Questionnaire

OBJECTIVES

To present the development of the European Adult Environment Questionnaire (EAEQ), to assess to what extent it covers the International Classification of Functioning, Disability and Health (ICF), and to describe the adequacy of the physical, social, and attitudinal environment to the specific needs of young adults with cerebral palsy (CP).

DESIGN

Cross-sectional.

SETTING

Administrative regions in France, Germany, Italy, Portugal, and Sweden.

PARTICIPANTS

Young adults with CP (N=357), with varying severity profiles, aged 19-28 years at time of interview (2018-20).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

Physical, social, and attitudinal environment unmet needs.

RESULTS

Relevant environmental factors (EFs) for young adults with CP were identified during focus groups in England and Portugal. EFs were mapped to the ICF environmental classification and the EAEQ analytical structure resulted from this linking procedure. It comprised 61 items, linked to 31 ICF environmental classification categories, and covered 4 of its 5 chapters. Content validity assessed with the bandwidth index (percentage coverage of ICF Core Sets for adults with CP) was satisfactory (79.3%). A descriptive analysis was carried out. Participants had a mean age of 24 years, 56% were men, 38% had severely limited mobility. Less than 16% reported unmet needs for EFs relating to home, college/work/day placement, and communication in the Products and technology chapter. Unmet needs were higher (>20%) for the other items in the Public use and Land development categories. Social support, attitudes, and understanding of relatives were often adequate to the participants' needs. The proportion of unmet needs varied by sex (women were more often concerned) and raised with increasing gross motor impairment.

CONCLUSION

The EAEQ describes in detail the adequacy of the environment to the specific needs of young adults with CP. Its ICF-based structure opens up possibilities for use in a universal conceptual framework.

Post-stroke Cognition is Associated with Stroke Survivor Quality of Life and Caregiver Outcomes: A Systematic Review and Meta-analysis

Disability arising from post-stroke cognitive impairment is a likely contributor to the poor quality of life (QoL) stroke survivors and their carers frequently experience, but this has not been summarily quantified. A systematic literature review and meta-analysis was completed examining the association between general and domain-specific post-stroke cognitive functioning and adult stroke survivor QoL, caregiver QoL, and caregiver burden. Five databases were systematically searched, and eligibility for inclusion, data extraction, and study quality were evaluated by two reviewers using a standardised protocol. Effects sizes (r) were estimated using a random effects model. Thirty-eight studies were identified, generating a sample of 7365 stroke survivors (median age 63.02 years, range 25-93) followed for 3 to 132 months post-stroke. Overall cognition (all domains combined) demonstrated a significant small to medium association with QoL, r = 0.23 (95% CI 0.18-0.28), p < 0.001. The cognitive domains of speed, attention, visuospatial, memory, and executive skills, but not language, also demonstrated a significant relationship with QoL. Regarding caregiver outcomes, 15 studies were identified resulting in a sample of 2421 caregivers (median age 58.12 years, range 18-82) followed for 3 to 84 months post-stroke. Stroke survivor overall cognitive ability again demonstrated a significant small to medium association with caregiver outcomes (QoL and burden combined), r = 0.17 (95% CI 0.10-0.24), p < 0.001. In conclusion, lower post-stroke cognitive performance is associated with significant reductions in stroke survivor QoL and poorer caregiver outcomes. Cognitive assessment is recommended early to identify those at risk and implement timely interventions to support both stroke survivors and their caregivers.

Effects of whole-body vibration training on physical function, activities of daily living, and quality of life in patients with stroke: a systematic review and meta-analysis

Purpose: This systematic review and meta-analysis aimed to evaluate the efficacy of whole-body vibration training (WBVT) in patients with stroke, specifically focusing on its effects on physical function, activities of daily living (ADL), and quality of life (QOL). Additionally, potential moderators influencing WBVT outcomes were explored. Methods: We conducted a systematic search of PubMed, Embase, and Cochrane Library from inception to September 2022. Eligible studies were randomized controlled trials employing WBVT in patients with stroke. Two investigators independently extracted the data and calculated the standardized mean difference (SMD) using random-effect models. Results: Twenty-five studies involving 991 patients were included in this meta-analysis. WBVT demonstrated significant reductions in spasticity (SMD = -0.33, 95% CI = -0.61 to -0.06, p = 0.02), improvements in motor function (SMD = 0.39, 95% CI = 0.16 to 0.61, p < 0.01), and enhancements in balance function (SMD = 0.28, 95% CI = 0.09 to 0.47, p < 0.01) in patients with stroke. However, no significant effects were observed for gait (SMD = -0.23, 95% CI = -0.50 to 0.04, p = 0.10), ADL (SMD = -0.01, 95% CI = -0.46 to 0.44, p = 0.97), or QOL (SMD = 0.12, 95% CI = -0.30 to 0.53, p = 0.59). Subgroup analyses revealed that variable frequency vibration and side-alternating vibration exhibited significant efficacy in reducing spasticity and improving motor and balance functions, while fixed frequency vibration and vertical vibration did not yield significant therapeutic benefits in these domains. Conclusion: Our findings indicate that WBVT may serve as a viable adjunct therapy for stroke patients to alleviate spasticity and enhance motor and balance functions. Variable frequency and side-alternating vibration appear to be crucial factors influencing the therapeutic effects of WBVT on these dysfunctions. Nonetheless, WBVT did not show significant effects on gait, ADL, or QOL in stroke patients. Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO/, identifier (CRD42022384319).

Self-management strategies for people with epilepsy: An overview of reviews

OBJECTIVE

This overview of systematic reviews aimed to appraise evidence regarding self-management strategies on health-related quality of life, self-efficacy, medication compliance, seizure status and psychosocial outcomes compared to usual care for people with epilepsy.

METHODS

Databases were searched until September 2022 using MeSH terms included OVID Medline, Embase and Cochrane. Following application of eligibility criteria, data were extracted and quality of articles was assessed using the AMSTAR2 checklist. A narrative synthesis of evidence included certainty of evidence evaluated using a Grading of Recommendations, Assessment, Development and Evaluation approach.

RESULTS

The 12 selected reviews contained three meta-analyses and 91 unique primary studies. One review considered only epilepsy with intellectual disability and three considered paediatrics. Interventions included technologically-based interventions, small group discussion, or counselling and educational programs. There was high certainty evidence to suggest self-management is associated with improvement in health-related quality of life and moderate certainty evidence to suggest improvement in depression symptoms. There was low certainty evidence to suggest a modest reduction in negative health events and a minimal increase in the satisfaction with life. There was no evidence of benefit favouring self-management on measures of adherence epilepsy self-management, perception of self-efficacy, medication adherence or seizure status.

SIGNIFICANCE

Despite high certainty evidence to suggest that self-management strategies for people with epilepsy improve health-related quality of life, benefits have not been demonstrated for outcomes that would be expected to be associated with these improvements, such as seizure status. These results provide support for self-management strategies to supplement usual care for people with epilepsy.

The Effectiveness of Telerehabilitation on Balance and Functional Mobility in Patients with Stroke: A Systematic Review and Meta-Analysis

Objective

The aim of this systematic review and meta-analysis was to investigate the effectiveness of telerehabilitation on improving balance and functional mobility in stroke survivors.

Methods

Comprehensive searching was conducted from inception to May 2022. The inclusion criteria were studies evaluating the effectiveness of telerehabilitation in stroke survivors. Data regarding participants, intervention, outcome measures, and main results were extracted. PEDro scale and the Grading of Recommendations Assessment Development and Evaluation (GRADE) were used to assess the methodological quality and quality of evidence, respectively.

Data Analysis

A total of fourteen articles) 594 patients) were included. A meta-analysis using a random-effect model was performed on thirteen studies )530 patients). Standardized mean difference (SMD) with 95% confidence interval (CI) was calculated for balance and functional mobility. Results: PEDro scale revealed ten good-quality studies, three fair-quality studies, and one poor-quality study. According to the available evidence, telerehabilitation has a small effect size in improving both balance (SMD 0.33 [95% CI 0.03 to 0.63]; P =0.03; low quality of evidence) and functional mobility (SMD 0.27 [95% CI 0.02 to 0.52]; P =0.03; low quality of evidence).

Conclusion

Telerehabilitation may improve balance and functional mobility in stroke survivors. However, it is evident that more high-quality research is required due to the existence of low to very low-quality evidence with limited confidence in the effect estimate.

Registration

Health-Related Quality of Life (HRQOL) Instruments and Mobility: A Systematic Review

Physical function is one of the most important constructs assessed in health-related quality of life (HRQOL), and it could be very useful to assess movement ability from the perspective of the patient. The objective of this study was to compare the content of the domains related to mobility covered by the HRQOL questionnaires based on the International Classification of Functioning, Disability and Health (ICF) and to evaluate their quality according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidance. For this, a systematic review was carried out in the databases Scopus, Web of Science and Science Direct. The inclusion criteria were development and/or validation studies about generic HRQOL measures, and the instruments had to include items related to mobility and studies written in English or Spanish. The comparison of content was performed using the ICF coding system. A total of 3614 articles were found, 20 generic HRQOL instruments were identified and 120 (22.4%) mobility-related items were found. Walking was the most represented category. Low-quality evidence on some measurement properties of the generic HRQOL instruments was revealed. The CAT-Health is a useful questionnaire to be used in rehabilitation due to its psychometric properties and its content.

Use of the International Classification of Functioning, Disability and Health (ICF) to expand and standardize the assessment of quality-of-life following a stroke: proposal for the use of codes and qualifiers

PURPOSE

Propose a way of coding and qualifying HRQoL following a stroke using the codes and qualifiers of the International Classification of Functioning, Disability and Health (ICF).

METHODS

An observational, cross-sectional study was conducted involving 51 individuals with hemiparesis resulting from a stroke. ICF codes related to the Stroke Specific Quality of Life (SS-QOL) scale were listed and subsequently classified using the generic ICF qualifiers, which range from .0 - no impairment to .4 - complete impairment. A simple mathematic calculation was proposed to convert the SS-QOL scores into ICF qualifiers.

RESULTS

The use of the ICF qualifiers revealed that the individuals exhibited a moderate level (.2) of quality of life, with mild impairment (.1) regarding upper limb function, language, self-care, and vision as well as severe impairment (.3) regarding social relations.

CONCLUSIONS

The proposal presented in this study allowed qualifying 43 ICF codes related to quality of life after a stroke in a simple, standardized manner, enabling the identification of different levels of impairment on each of the domains of the SS-QOL scale. This coding standardizes the evaluation, facilitates communication between healthcare providers, and systematizes the collection of data and information on health.Implications for rehabilitationProposal for qualifying concepts related to body functions, activity & participation, and environmental factors in a simple, standardized manner.The proposed mathematic calculation is simple and easy to understand, which minimizes the occurrence of errors.Possibility to identify different levels of impairment in each of the domains of the Stroke Specific Quality of Life scale, facilitating the establishment of individualized, longitudinal care.The ICF codes standardize the evaluation, facilitate communication between healthcare providers, and systematize the collection of data and information on health and functioning.

Assessment of Functioning in Older Adults Hospitalized in Long-Term Care in Portugal: Analysis of a Big Data

Background

Functioning assessment is a key tool for health professionals to characterize the person's degree of dependence and plan care.

Objectives

The objectives were: (1) know the functioning components of older adults hospitalized in the National Network of Continuous Integrated Health Care (NNCIHC) in Portugal; and (2) compare the conceptual frameworks used in this network with the International Classification of Functioning, Disability and Health (ICF).

Methods

A longitudinal retrospective study is made with 171,414 individuals aged 65 years and over. The Principal Components Analysis (PCA) was realized to reduce the number of variables, previously suggested by a scoping review, about the concepts that characterize the functionality. Then, a consensus meeting was held, where the items were matched with the ICF.

Results

The average age of the sample is 80.17 years old (SD = 7.383), predominantly female (59%), without a spouse (54%), and with <6 years of education (56.4%). Four concepts were grouped: mobility, life daily activities, instrumental activities, and cognitive status that demonstrated good internal consistency. Most items correspond to ICF, except for the item "taking medication."

Conclusion

Theoretical and conceptual similarities support the use of instruments based on the ICF in Portugal's healthcare network. We suggest that ICF also encompasses a specific dimension related to medication management, given its importance for people's health.

Self-reported quality of life following stroke: a systematic review of instruments with a focus on their psychometric properties

PURPOSE

To evaluate the psychometric properties of common health-related quality-of-life instruments used post stroke and provide recommendations for research and clinical use with this diagnostic group.

METHODS

A systematic review of the psychometric properties of the five most commonly used quality-of-life measurement tools (EQ-5D, SF-36, SF-6D, AQoL, SS-QOL) was conducted. Electronic searches were performed in MEDLINE, CINAHL, and EMBASE on November 27th 2019. Two authors screened papers against the inclusion criteria and where consensus was not reached, a third author was consulted. Included papers were appraised using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist and findings synthesized to make recommendations.

RESULTS

A total of n = 50,908 papers were screened and n = 45 papers reporting on 40 separate evaluations of psychometric properties met inclusion criteria (EQ-5D = 19, SF-36 = 16, SF-6D = 4, AQoL = 2, SS-QOL = 4). Studies reported varied psychometric quality of instruments, and results show that psychometric properties of quality-of-life instruments for the stroke population have not been well established. The strongest evidence was identified for the use of the EQ-5D as a quality-of-life assessment for adult stroke survivors.

CONCLUSIONS

This systematic evaluation of the psychometric properties of self-reported quality-of-life instruments used with adults after stroke suggests that validity across tools should not be assumed. Clinicians and researchers alike may use findings to help identify the most valid and reliable measurement instrument for understanding the impact of stroke on patient-reported quality of life.

Measures of movement and mobility used in clinical practice and research: a scoping review

OBJECTIVE

The first objective of this scoping review was to identify all the tools designed to measure movement or mobility in adults. The second objective was to compare the tools to the conceptual definitions of movement and mobility by mapping them to the International Classification of Functioning, Disability and Health (ICF).

INTRODUCTION

The concepts of movement and mobility are distinct concepts that are often conflated, and the differences are important to patient care. Movement is a change in the place or position of a part of the body or of the whole body. Mobility is derived from movement and is defined as the ability to move with ease. Researchers and clinicians, including nurses, physiotherapists, and occupational therapists who work with adults and in rehabilitation, need to be confident that they are measuring the outcome of interest.

INCLUSION CRITERIA

This scoping review considered studies that included participants who are adults, aged 19 and older, with any level of ability or disability. The concepts of interest were tools that measured movement or mobility relative to the human body. Studies were considered regardless of country of origin, health care setting, or sociocultural setting.

METHODS

CINAHL, Health and Psychosocial Instruments, MEDLINE, and Embase were searched in June 2018 and OpenGrey, Dissertation Abstracts International, and Google Scholar were searched in November 2018. The searches were limited to articles in English, and the date range was from the inception of the database to the current date. Data were extracted from the studies using a custom data extraction tool. Once tools were identified for analysis, they were coded using the table format developed by Cieza and colleagues.

RESULTS

There were 702 unique tools identified, with 651 of them available to be coded for the ICF. There were 385 ICF codes used when coding the tools. From these codes, the percentage of codes of the defining attributes of movement and mobility that were covered could be calculated, as well as the percentage of tool items that were linked to the antecedents, consequences, or defining attributes of movement or mobility.

CONCLUSIONS

Although there are many tools that measure only movement or mobility, there are many that measure a mixture of the defining attributes as well as the antecedents and consequences. The tool name alone should not be considered a guarantee of the concept measured, and tool selection should be done with a critical eye. This study provides a starting point from which clinicians and researchers can find tools that measure the concepts of movement and mobility of interest and importance to their patient population.

Efficacy of task-specific circuit training on physical activity levels and mobility of stroke patients: A randomized controlled trial

BACKGROUND

Impaired mobility is related to low physical activity (PA) levels observed after stroke. Therapeutic approaches, such as task-specific circuit training (TSCT), used to improve mobility in individuals with stroke, could also improve PA levels.

OBJECTIVE

To investigate the efficacy of TSCT, focused on both upper (UL) and lower (LL) limbs, in improving PA levels and mobility (primary outcomes), as well as muscle strength, exercise capacity, and quality of life (secondary outcomes) in subjects with stroke.

METHODS

A randomized controlled trial with 36 subjects with chronic stroke was conducted. Experimental group: TSCT, involving both UL and LL.

CONTROL GROUP

global stretching, memory exercises, and education sessions. Both groups received 60 minute sessions/week over 12 weeks. Outcomes were measured at baseline, post-intervention and 16 week follow-up.

RESULTS

No changes were found for primary and secondary outcomes (0.11≤p≤0.99), except for quality of life, which improved in the experimental group post-intervention and 16 week follow-up (p = 0.02).

CONCLUSION

TSCT focused on both UL and LL was not effective on PA levels and mobility of individuals with chronic stroke, however, improvements in quality of life were observed. Since this is the first study to investigate this combined training aimed at improving PA levels, future studies are necessary to better understand the impact of this type of intervention.

Collaborative Care Model Based Telerehabilitation Exercise Training Program for Acute Stroke Patients in China: A Randomized Controlled Trial

BACKGROUND

Early rehabilitation has been proved very important for stroke patients. However, the effective model of transitioning from early in-hospital rehabilitation to discharge rehabilitation using the collaborative remote rehabilitation nursing model has not been thoroughly studied.

OBJECTIVE

To explore the feasibility and effectiveness of collaborative care model based telerehabilitation exercise training for acute stroke patients.

METHODS

A randomized controlled clinical trial was conducted. Patients were recruited and randomly divided into intervention and control group. Both groups were given regular treatment and acute rehabilitation nursing instructions during hospitalization. The control group was followed by regular telephone follow-up after discharge. The intervention group received Internet-based remote rehabilitation project after discharge. Motor function, balance ability and quality of life were measured at the day of discharge, the 4^th week, 8^th week and 12^th week after patients were discharged. The CONSORT checklist was used to check the procedure.

RESULTS

A total of 61 patients completed the study, 30 cases in the intervention group and 31 cases in the control group. Both groups were significantly improved in terms of motor function and quality of life, but the intervention group showed greater improvement in Fugl-Meyer Motor Function Assessment (intervention group = 83.70 ± 4.44, control group = 75.29 ± 2.89), Berg Balance Scale (intervention group = 43.13 ± 2.32, control group = 38.29 ± 2.70) and Stroke-Specific Quality of Life Scale (intervention group = 190.57 ± 5.09, control group = 175.90 ± 5.78). Group-time interaction was significant in motor function and quality of life.

CONCLUSION

Collaborative care model based telerehabilitation exercise training program can safely and effectively improve the recovery of motor function and improve the quality of life in patients with stroke.

Instrumentos da prática clínica com versão em português e a abrangência de seus conteúdos usando a CIF como referência: uma revisão sistemática

RESUMO A prática clínica tem sido subsidiada por instrumentos que permitem acessar e registrar informações de funcionalidade e saúde dos indivíduos. Uma forma de conhecer qual conteúdo da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) os instrumentos contemplam é usá-la como referência para auxiliar o profissional na escolha do mais adequado para acessar informações biopsicossociais. O objetivo foi identificar instrumentos da prática clínica em saúde que tiveram seu conteúdo ligado com a CIF e a existência de versão na língua portuguesa deles. Para tanto foi realizada uma revisão sistemática nas bases de dados SciELO Brasil, Lilacs e PubMed com os descritores “CIF”, “questionário” e “regra de ligação” em português e inglês. Três pesquisadores independentes realizaram a seleção, e o nível de concordância foi obtido pelo coeficiente Kappa. Os critérios de elegibilidade foram: estudos primários de ligação de conteúdo de questionários, escalas, índices e checklists com a CIF publicados após 2001 em língua portuguesa ou inglesa. Foram incluídos 61 artigos, sendo 19 de origem brasileira. Dos 250 instrumentos ligados à CIF, 158 (63,2%) apresentaram versão em português sendo que dos 37 que mais se repetiram nos estudos, dois não apresentam essa versão. O coeficiente Kappa mostrou concordância entre moderada e boa (p<0,001). Este estudo apresentou um panorama da ligação de conteúdo de instrumentos da prática clínica à CIF identificando quais têm versão em língua portuguesa, o que contribuirá para o potencial fortalecimento da abordagem biopsicossocial dos profissionais de saúde.

Content Comparison of Aquatic Therapy Outcome Measures for Children with Neuromuscular and Neurodevelopmental Disorders Using the International Classification of Functioning, Disability, and Health

Currently, aquatic exercise is among the most common physical activity modalities for children with neuromuscular and neurodevelopmental disorders. However, the outcome measures that should be routinely used by therapists working in this specific health-care context have not been widely studied. The purpose of the study was to identify and compare the content of outcome measures used in aquatic physiotherapy for children, employing the International Classification of Functioning, Disability and Health (ICF) as a framework. A literature review was used to identify aquatic functioning outcome measures for children with neuromuscular and neurodevelopmental disorders. Content comparison of outcome measures identified was linked to the ICF following the linking guidelines, and content-related metrics were used to analyze them. Four outcome measures were identified (HAAR, Conatser, WOTA 1 and 2, and SWIM), which contained a total of 116 meaningful concepts and were linked to 35 ICF 2nd level categories. The greatest number of items assessed activity and participation categories. Large differences were found in reference to the density of content. For content diversity, the measures were all below 0.5. The identified outcome measurements showed homogeneity with respect to the theoretical foundation; however, some differences were found in terms of content analysis.

The content comparison of health-related quality of life measures in heart failure based on the international classification of functioning, disability, and health: a systematic review

Introduction: Due to the necessity of assessing the health-related quality of life (HRQOL) in heart failure (HF) and the increased use of the International Classification of Functioning, Disability, and Health (ICF) for making a content comparison of measurement instruments, the present study aimed to evaluate the relationship between the instruments and ICF. To this aim, the disease-specific HRQOL instruments in HF were identified, and then psychometric properties and content comparison of included instruments were conducted by linking to ICF. Methods: Disease-specific HRQOL instruments in HF were identified through a comprehensive and systematic search strategy. Then, the psychometric properties of included instruments were determined, and their contents were analyzed and compared based on the ICF coding system. In addition, each instrument was independently linked to ICF by two researchers based on standardized linking rules, and finally their degree of agreement was assessed by the Cohen's kappa coefficient. Results: Ten instruments including a total of 247 items and 417 concepts were linked to 124 different ICF categories. Further, 39 (31.5%), 65 (52.5%), 13 (10.4%), and 7 (5.6%) categories were linked to body function, activity and participation, environmental factors, and body structure, respectively. According to the content analysis approach and psychometric properties, the appropriate measurement instruments were Kansas City Cardiomyopathy and Minnesota living with HF questionnaires, respectively. Conclusion: Content comparison provides researchers with valuable information on the instrument heterogeneity and overlapping, which results in selecting the most appropriate measurement instrument based on a specific clinical context.

Disabled life expectancy with and without stroke: a 10-year Japanese prospective cohort study

PURPOSE

A stroke is a debilitating condition that can cause lifelong disability, severely limiting the ability of individuals to perform daily activities. In Japan, strokes are the fourth leading cause of death; however, no previous studies have examined the influence of strokes on a disabled or disability-free life for older Japanese residents. This study aims to address this gap.

METHODS

The study used data from the Nihon University Japanese Longitudinal Study of Aging (NUJLSOA) and incidence-based multistate life tables to estimate disabled and disability-free life expectancy based on the stroke status of Japanese residents aged 65 and older.

RESULTS

Japanese stroke survivors aged 65 who experienced an initial disability-free state could expect to live approximately 3 fewer total years of life, 4-5 fewer years in a disability-free state, and 1-2 more years in a disabled state compared to those without history of a stroke (p < 0.05). For those disabled at the beginning of the survey interval, the differences between individuals with and without stroke history were also similar to those disability-free at the beginning of the survey interval (2-4 and 5-6 fewer total and disability-free years, respectively) (p < 0.05). The same pattern was observed for older age groups.

CONCLUSION

Older adults who have experienced a stroke could experience a shorter total life expectancy, shorter disability-free life expectancy, and longer disabled life expectancy than those who have not experienced a stroke. These results can inform policymakers and rehabilitation practitioners on stroke survivor long-term care needs and their post-stroke health status.

Application of the refinements of ICF linking rules to the Visual Analogue Scale, Roland Morris questionnaire and SF-36

The Visual Analogue Scale (VAS), Roland Morris Disability Questionnaire (RMDQ), Short Form Health Survey (SF-36) are broadly used and had their content linked to ICF by the linking rules of 2002 and 2005. In 2016 were refined and were not applied yet. To apply the refinements of ICF linking rules to VAS, RMDQ, and SF-36. Two health professionals identified the meaningful concepts and linked to the most precise ICF categories and a third triggered in divergences. The degree of agreement was calculated by kappa statistic. There was almost perfect agreement (Kappa=0.93 p<0,001). The main concept of VAS was linked to ICF category b280, the 24 main concepts of RMDQ linked to b28013, and 27 additional linked to other categories. The SF-36 had 36 main concepts and 30 additional concepts identified which 27 were definable by the ICF and 17 do not. From the total of ICF linked concepts, 39 refer to Body Functions, 57 to Activities and Participation and 4 to Environmental Factors. The refinements of linking rules propitiated more clarity in the process to identify, to link instruments content with ICF and to expose the results. Thus, increased the number of identified and linked concepts as well as the categories in the instruments.

Disability and health outcomes - from a cohort of people on long-term anti-retroviral therapy

Human-immunodeficiency virus (HIV)/Acquired immunodeficiency Syndrome (AIDS) remains a major health problem in South Africa - even after two decades since the introduction of antiretroviral therapy (ART). Long-term survival with HIV is associated with new health-related issues and a risk of functional limitation/disability. The aim of this study was to assess functional limitation associated with HIV/AIDS among people living with HIV (PLHIV) in South Africa. This study is a cross-sectional survey using a cohort in an urban area in Gauteng province, South Africa. Data were collected using questionnaires through an interview process. The information collected included aspects such as demographics, livelihood, the state of mental and physical health, adherence and disability. A total of 1044 participants with an average age of 42 ± 12 years were included in the study, with 51.9% of the participants reporting functional limitations (WHODAS ≥ 2). These were reported mainly in the domains of participation (40.2%) and mobility (38.7%). In addition, adherence to ART, symptoms of poor physical health and depression were strongly associated with their functional limitations/disability. HIV as a chronic disease is associated with functional limitations that are not adequately addressed and pose a risk of long-term disability and negative adherence outcomes. Therefore, wellness for PLHIV/AIDS needs to include interventions that can prevent and manage disability.

Applying modern measurement approaches to constructs relevant to evidence-based practice among Canadian physical and occupational therapists

BACKGROUND

Evidence-based practice (EBP) is a complex process. To quantify it, one has to also consider individual and contextual factors using multiple measures. Modern measurement approaches are available to optimize the measurement of complex constructs. This study aimed to develop a robust measurement approach for constructs around EBP including practice, individual (e.g. knowledge, attitudes, confidence, behaviours), and contextual factors (e.g. resources).

METHODS

One hundred eighty-one items arising from 5 validated EBP measures were subjected to an item analysis. Nominal group technique was used to arrive at a consensus about the content relevance of each item. Baseline questionnaire responses from a longitudinal study of the evolution of EBP in 128 new graduates of Canadian physical and occupational therapy programmes were analysed. Principles of Rasch Measurement Theory were applied to identify challenges with threshold ordering, item and person fit to the Rasch model, unidimensionality, local independence, and differential item functioning (DIF).

RESULTS

The nominal group technique identified 70/181 items, and modified Delphi approach identified 68 items that fit a formative model (2 related EBP domains: self-use of EBP (9 items) and EBP activities (7 items)) or a reflective model (4 related EBP domains: attitudes towards EBP (17 items), self-efficacy (9 items), knowledge (11 items) and resources (15 items)). Rasch analysis provided a single score for reflective construct. Among attitudes items, 65% (11/17) fit the Rasch model, item difficulties ranged from - 7.51 to logits (least difficult) to + 5.04 logits (most difficult), and person separation index (PSI) = 0.63. Among self-efficacy items, 89% (8/9) fit the Rasch model, item difficulties ranged from - 3.70 to + 4.91, and PSI = 0.80. Among knowledge items, 82% (9/11) fit the Rasch model, item difficulties ranged from - 7.85 to 4.50, and PSI = 0.81. Among resources items, 87% (13/15) fit the Rasch model, item difficulties ranged from - 3.38 to 2.86, and PSI = 0.86. DIF occurred in 2 constructs: attitudes (1 by profession and 2 by language) and knowledge (1 by language and 2 by profession) arising from poor wording in the original version leading to poor translation.

CONCLUSIONS

Rasch Measurement Theory was applied to develop a valid and reliable measure of EBP. Further modifications to the items can be done for subsequent waves of the survey.

Identification of categories of the International Classification of Functioning, Disability and Health in functional assessment measures for stroke survivors: a systematic review

Objective: Perform a systematic review to identify the categories of the International Classification of Functioning, Disability and Health linked to the concepts measured by functional assessment tools validated for Brazilian Portuguese: Timed Up and Go test, Functional Independence Measure, Barthel Index, and Rivermead Mobility Index and Modified Rankin Scale.Methods: The Medline, Embase and CINAHL databases were consulted using a standardized search strategy. The studies were summarized using a pre-established set of specific criteria for the adequate linkage between the concepts identified in the assessment measures and the International Classification of Functioning, Disability and Health categories. Two independent reviewers performed the selection of the studies, data extraction and evaluation of the results.Results: The search of the databanks led to the retrieval of 99 studies. However, only six articles were included in the present review. The linkage results of the studies included in the review were divergent, likely due to the taxonomic complexity of the International Classification of Functioning, Disability and Health, the difficulty in clearly relating the concepts of the assessment measures to the classifications and the fact that not all linkage rules were followed. "Activities and participation" was the most evaluated component, with mobility the most frequently covered category in the measures, followed by self-care. Among the measures analyzed, the Functional Independence Measure addresses a greater number of categories and therefore has the most concepts related to the International Classification of Functioning, Disability and Health, followed by the Barthel Index, Modified Rankin Scale, Rivermead Mobility Index and Timed Up and Go test. The Modified Rankin Scale was the assessment tool that most evaluated categories related to environmental factors.Conclusion: The Functional Independence Measure has more concepts related to the International Classification of Functioning, Disability and Health, since it addresses a greater number of categories. These findings can help guide health professionals in the selection of assessment tools for the evaluation of post-stroke functioning, making viable the use of the International Classification of Functioning, Disability and Health categories in clinical practice and public health services.Implications for rehabilitationThis study standardized identification of the International Classification of Functioning, Disability and Health categories in the main outcome measures used to assess post-stroke functional capacity.Functional Independence Measure has more concepts related to the International Classification of Functioning, Disability and Health compared to other functional assessment instruments.Findings can enable physiotherapists and researchers choose the most appropriate measure that best corresponds to their field of interest.These results facilitate the implementation of the International Classification of Functioning, Disability and Health in clinical practice.Use of International Classification of Functioning, Disability and Health categories can standardize information on functional health.

Examination of the relevance of the ICF cores set for stroke by comparing with the Stroke Impact Scale

PURPOSE

To examine if the International Classification of Functioning (ICF) core set for stoke contains problems that are relevant for the persons living with stroke as expressed in the Stroke Impact Scale (SIS).

METHODS

Cross-sectional study of 242 persons with previous stroke. The agreement between the perceived problems in the SIS items and problems in the categories of Comprehensive ICF Core Set for stroke were analyzed using percent of agreement and Kappa statistic.

RESULTS

The analyses between 57 items of the SIS and 31 second-level categories of the ICF were conducted. The problems in domains of "Mobility", "Activities of daily living", "Hand function", "Strength" in the SIS had moderate agreement when compared to ICF categories. The SIS domains of "Emotion" and "Communication", as well as some aspects of the "Memory" had slight or fair agreement with corresponding ICF categories. The results of the study suggest that there is acceptable agreement between persons after stroke and health professionals in the physical aspects, but rather poor agreement in the cognitive and emotional aspects of functioning.

CONCLUSIONS

Health professionals do not fully capture the magnitude of emotional or social problems experienced by persons after stroke when using the ICF Core Set as a framework for evaluation. Implications for Rehabilitation The ICF Core Set for Stroke provides comprehensive list of possible health and health related outcomes for persons after stroke. Problems reported in condition-specific patient-reported outcome scales can be important in decision making in rehabilitation. Patients and health professionals tend to agree more on physical than cognitive problems. Examination of the relevance of the ICF cores set for stroke by comparing with the Stroke Impact Scale.

Content comparison of guideline-recommended instruments used in treatment for alcohol use disorders

PURPOSE

Practice guidelines recommend the use of standardized instruments in the treatment of alcohol use disorders (AUDs); however, the extent to which these instruments assess patients' functioning is unclear. The aim of this study was to examine the domains of functioning and contextual factors contained in guideline-recommended instruments, using the International Classification of Functioning, Disability, and Health (ICF) as a reference.

MATERIALS AND METHODS

We identified instruments by reviewing AUD treatment guidelines used in Germany, Canada, Australia and New Zealand, United Kingdom, and United States. We included instruments which were available in English free of charge, we excluded instruments developed solely for diagnostic or epidemiological purposes and those for children or adolescents. Following a standardized set of rules, two health care researchers identified the concepts contained in the items on the instruments and independently linked them to ICF categories.

RESULTS

A total of 10 instruments were included. Among 517 items, 752 meaningful concepts (MCs) were derived, and 622 of them were linked to the ICF. Inter-rater agreement was κ = 0.61. One hundred eighty eight MCs referred to personal factors, 175 to body functions, 168 to activity and participation, and 91 to environmental factors. The most frequently linked ICF chapter was b1 (mental functions).

CONCLUSIONS

Instruments recommended in AUD treatment guidelines vary considerably in their assessment of patients' functioning and contextual factors. Within the investigated instruments, environmental factors are under-represented in comparison to body functions and personal factors. ICF linkage provides guidance for clinicians and researchers in the selection of appropriate instruments. Implications for rehabilitation Since instruments that are recommended in alcohol treatment guidelines vary considerably in respect the functioning domains and context factors they cover, it may be challenging for clinicians to select instruments relevant to their treatment context. Using the ICF as framework, our results provide guidance for clinicians in how to select appropriate instruments. Within the investigated instruments, environmental factors and activities and participation are under-represented in comparison to body functions and personal factors. Clinicians may employ AUD-unspecific or ICF-based instruments to cover these components if needed.

Applying the ICF linking rules to compare population-based data from different sources: an exemplary analysis of tools used to collect information on disability

BACKGROUND

Data on disability are regularly collected by different institutions or ministries using specific tools for different purposes, for instance to estimate the prevalence of disability or eligibility of specific populations for social benefits. The interoperability of disability data collected in countries is essential for policy making and to monitor the implementation of the Convention on the Rights of Persons with Disabilities. The first objective of this paper is to map and compare tools that collect data on disability for different purposes, more specifically the Brazilian National Health Survey and the Brazilian Functioning Index to the World Health Organization (WHO) and the World Bank Model Disability Survey (MDS), currently recommended as a standard tool for disability measurement. The second objective is to demonstrate the usefulness and value of the International Classification of Functioning, Disability and Health Linking Rules to map and compare population-based surveys and other content-related tools collecting data on disability, even when these have already been developed based on the International Classification of Functioning, Disability and Health.

METHODS

Disability information collected with the three different tools was mapped and compared using the International Classification of Functioning, Disability and Health Linking Rules.

RESULTS

Although the disability module in the Brazilian National Health Survey is fundamentally different from the MDS, the mapping disclosed that several modules of the Brazilian National Health Survey already cover many aspects necessary to estimate prevalence and understand disability as currently recommended by the WHO and the World Bank. The Brazilian Functioning Index and the MDS are both based on the International Classification of Functioning, Disability and Health and are very similar in the approach and content of their questions on functioning. Specific information on environmental factors is essential to identify needs and barriers, as well as to devise procedures to reduce injustice and inequalities. This information is still not targeted broadly enough in both the Brazilian National Health Survey and the Brazilian Functioning Index.

CONCLUSIONS

Overall, this mapping exercise showed that applying the International Classification of Functioning, Disability and Health linking rules to population-based data coming from different sources provides researchers and stakeholders involved in decision-making with standardized and straightforward information about overlaps and gaps. Implications for Rehabilitation Data on functioning and disability regularly collected with different purposes and by different institutions or ministries within a country can be compared using the International Classification of Functioning, Disability and Health as a reference framework and the International Classification of Functioning, Disability and Health linking rules. The recently published refinements of the International Classification of Functioning, Disability and Health Linking Rules go beyond the sole linking to International Classification of Functioning, Disability and Health categories and provide standardized procedures to document the perspective of linked questions or the categorization of response options. They are therefore useful to compared tools that have been developed based on the International Classification of Functioning, Disability and Health. The current disability module of the Brazilian Health Survey needs a revision to be suitable to collect data on disability that is Convention on the Rights of Persons with Disabilities conform and guarantees interoperability with disability data from other sources in Brazil, especially from disability assessment for social benefits and implementation of policies.

Linking of the quality of life in neurological disorders (Neuro-QoL) to the international classification of functioning, disability and health

BACKGROUND

The quality of life in neurological disorders (Neuro-QoL) is a U.S. National Institutes of Health initiative that produced a set of self-report measures of physical, mental, and social health experienced by adults or children who have a neurological condition or disorder.

OBJECTIVE

To describe the content of the Neuro-QoL at the item level using the World Health Organization's international classification of functioning, disability and health (ICF).

METHODS

We assessed the Neuro-QoL for its content coverage of functioning and disability relative to each of the four ICF domains (i.e., body functions, body structures, activities and participation, and environment). We used second-level ICF three-digit codes to classify items into categories within each ICF domain and computed the percentage of categories within each ICF domain that were represented in the Neuro-QoL items.

RESULTS

All items of Neuro-QoL could be mapped to the ICF categories at the second-level classification codes. The activities and participation domain and the mental functions category of the body functions domain were the areas most often represented by Neuro-QoL. Neuro-QoL provides limited coverage of the environmental factors and body structure domains.

CONCLUSIONS

Neuro-QoL measures map well to the ICF. The Neuro-QoL-ICF-mapped items provide a blueprint for users to select appropriate measures in ICF-based measurement applications.

Functioning in patients with schizophrenia: a systematic review of the literature using the International Classification of Functioning, Disability and Health (ICF) as a reference

PURPOSE

To identify and quantify the main concepts included in published studies focusing on individuals with schizophrenia using the International Classification of Functioning, Disability and Health (ICF).

METHODS

Searches (limited to those published from 2008 to 2012) were performed in MEDLINE, PsycINFO and CINAHL. Included studies described participants with schizophrenia, were original articles and included only subjects who were at least 18 years of age at study entry. All concepts underlying the measures and the text of the articles were extracted, and they were linked to ICF categories using standardized rules.

RESULTS

From the 3584 abstracts retrieved, 348 were randomly selected, and of these, 206 studies met the inclusion criteria. A total of 17,141 concepts were extracted, 84.8% of which could be linked to 491 ICF categories: 222 (45.21%) of the categories referred to Body Functions, 29 (5.91%) to Body Structures, 186 (37.88%) to Activities and Participation and 54 (11%) to Environmental Factors. Seventy second-level categories were reported in at least 5% of all studies: 30 of these categories referred to Body Functions, 2 to Body Structures, 34 to Activities and Participation and 4 to Environmental Factors.

CONCLUSION

The study has allowed us to identify and quantify the main concepts included in studies focusing on people with schizophrenia using the ICF. The majority of the concepts refer to Body Functions and Activities and Participation, rather than to Body Structures and Environmental Factors.

Mapping the Effect of Psoriatic Arthritis Using the International Classification of Functioning, Disability and Health

Objective.

The effect of a disease can be categorized by a standardized reference system: the International Classification of Functioning, Disability and Health (ICF). The objective was to map the effect of psoriatic arthritis (PsA) from the patient’s perspective to the ICF.

Methods.

A systematic literature review was performed. Qualitative publications reporting domains of impact important for patients with PsA were identified using the following terms: (“psoriatic arthritis”) AND (“quality of life” OR “impact”). Meaningful concepts were extracted from the publications, grouped into domains and linked to the ICF categories. The number of concepts linked to each ICF category and to each ICF level was calculated. The number of concepts not linkable was also calculated.

Results.

Eleven studies (13 articles) were included in the analysis. Twenty-five domains of impact were cited, of which the ability to work/volunteer and social participation were the most cited (both by 10 studies). In total, 258 concepts were identified, of which 217 could be linked to 136 different ICF categories; 41 concepts, mostly personal factors, could not be precisely linked. The most represented ICF component was activities and participation (42.6%) rather than body structures (10.3%) or body functions (29.4%). Ten studies (90.9%) reported impairments in the ability to work/volunteer and social participation, and 7 (63.6%) reported leisure activities, family and intimacy, pain, skin problems, and body image.

Conclusion.

PsA widely affects all aspects of patients’ lives, in particular aspects related to activities and participation. The ICF is a useful approach for the classification of disease effect.

Is health-related quality of life between 90 and 180 days following stroke associated with long-term unmet needs?

PURPOSE

Understanding the relationship between health-related quality of life (HRQoL) and long-term unmet needs is important for guiding services to optimise life following stroke. We investigated whether HRQoL between 90 and 180 days following stroke was associated with long-term unmet needs.

METHODS

Data from Australian Stroke Clinical Registry (AuSCR) registrants who participated in the Australian Stroke Survivor Needs Survey were used. Outcome data, including the EQ-5D, are routinely collected in AuSCR between 90 and 180 days post-stroke. Unmet needs were assessed at a median of 2 years and categorised into: health; everyday living; work/leisure; and support domains. Multivariable regression was used to determine associations between the EQ-5D dimensions and the likelihood of experiencing unmet needs and the visual analogue scale (VAS) (rating 0-100) and number of reported unmet needs.

RESULTS

In total, 173 AuSCR registrants completed the Needs Survey (median age 69 years, 67 % male; 77 % ischaemic stroke). VAS scores were negatively associated with the number of reported long-term unmet needs [irr 0.98, (95 % CI 0.97, 0 99) p < 0.001]. Having EQ-5D activity limitations was associated with unmet living needs (aOR 4.5, 95 % CI 1.1, 18.8). Requiring living supports at 90-180 days was associated with unmet health needs (aOR 4.9, 95 % CI 1.5, 16.1). Those with pain at 90-180 days were less likely to report unmet health (aOR 0.09, 95 % CI 0.02, 0.4) and support needs (aOR 0.2, 95 % CI 0.06, 0.6).

CONCLUSION

Routinely collected HRQoL data can identify survivors at risk of experiencing long-term unmet needs. This information is important for targeting service delivery to optimise outcomes following stroke.

Toward the Development of a Universal Outcome Instrument for Spine Trauma: A Systematic Review and Content Comparison of Outcome Measures Used in Spine Trauma Research Using the ICF as Reference

STUDY DESIGN

A systematic literature review.

OBJECTIVE

The aim of this study was (1) to identify patient-reported and clinician-based outcome measures most frequently used to evaluate the function and health of spine trauma patients, (2) to identify and quantify the concepts of these measures using the International Classification of Functioning, Disability, and Health (ICF) as reference, and (3) to describe their clinimetric properties.

SUMMARY OF BACKGROUND DATA

There is a real need for a disease-specific outcome instrument to measure the effect size of various treatment options in a variety of traumatic spinal column injuries.

METHODS

A systematic literature search was conducted in several databases. From the included studies, outcome measures were extracted. The items and underlying concepts of the identified outcome measures were specified and linked to the ICF categories. Finally, as far as available in literature, the clinimetric properties of the obtained measures were analyzed.

RESULTS

Out of 5117 screened references, 245 were included, and 17 different frequently used outcome measures were identified. Meaningful concepts of the items and response options of the retrieved outcome measures were linked to a total of 105 different ICF categories, aggregated to 57 first- or second-level categories. The categories were linked to the components activities and participation (n = 31), body functions (n = 17), environmental factors (n = 8), and body structures (n = 1). Overall, there is only limited evidence on the measurement properties, except for some disease-specific questionnaires, such as Oswestry Disability Index, Roland-Morris Disability Questionnaire, Neck Disability Index, and Cervical Spine Outcome Questionnaire.

CONCLUSION

The current systematic literature review revealed great diversity in the use and content of outcome measures to evaluate the functioning and health of spine trauma patients, with 17 different outcome measures linked to 57 unique ICF categories. This study creates an evidence base for a consensus meeting during which a core set of ICF categories for outcome measurement in spine trauma will be decided.

Functioning in lymphoedema from the health professionals' perspective using the international classification of functioning, disability and health as a reference

PURPOSE

To capture the views of different health care providers involved in the treatment of patients with lymphoedema from various countries around the world on the functioning of lymphoedema patients and the factors influencing functioning of these patients using the international classification of functioning, disability and health (ICF).

METHOD

A worldwide e-mail survey with questions based on components of the ICF.

RESULTS

In total, 142 health professionals from seven different health professions and 20 different countries answered the questions. The aspects of functioning that were named by the health professionals could be linked to 359 different ICF categories. Of these categories, 109 belonged to body functions (30.4%), 55 to body structures (15.3%), 121 to activities and participation (33.7%) and 74 to environmental factors (20.6%). Overall, the most mentioned items were health services, systems and policies, immunological system functions, looking after one's health, products and technology for personal use in daily life and dressing.

CONCLUSIONS

The ICF provided a valuable reference for identifying concepts in statements from international health care professionals experienced in the treatment of lymphoedema patients. The results of this research will be used in the development of ICF core sets for lymphoedema.

Correlation between upper limb function and oral health impact in stroke survivors

[Purpose] The aim of the present study was to evaluate the relationship between upper limb impairment and oral health impact in individuals with hemiparesis stemming from a stroke. [Subjects and Methods] The study subjects were conducted with a sample of 27 stroke survivors with complete or partial hemiparesis with brachial or crural predominance. The 14-item short version of the Oral Health Impact Profile was used to evaluate perceptions of oral health. The Brazilian version of the Stroke Specific Quality of Life Scale was used to evaluate perceptions regarding quality of life. [Results] A statistically significant association was found between the upper extremity function subscale of the SSQOL-Brazil and the impact of oral health evaluated using the OHIP-14, with a strong correlation found for the physical pain subscale, moderate correlations with the functional limitation, psychological discomfort, physical disability, social disability and social handicap subscales as well as a weak correlation with the psychological disability subscale. Analyzing the OHIP-14 scores with regard to the impact of oral health on quality of life, the most frequent classification was weak impact, with small rates of moderate and strong impact. [Conclusion] Compromised upper limb function and self-perceived poor oral health, whether due to cultural resignation or functional disability, exert a negative impact on the quality of life of individuals with hemiparesis stemming from a stroke.

Using the international classification of functioning, disability and health to expand understanding of paralysis in the United States through improved surveillance

BACKGROUND

Surveillance on paralysis prevalence has been conceptually and methodologically challenging. Numerous methods have been used to approximate population-level paralysis prevalence estimates leading to widely divergent prevalence estimates.

OBJECTIVE/HYPOTHESES

To describe three phases in use of the International Classification of Functioning, Disability and Health (ICF) as a framework and planning tool for defining paralysis and developing public health surveillance of this condition.

METHODS

Description of the surveillance methodology covers four steps: an assessment of prior data collection efforts that included a review of existing surveys, registries and other data collection efforts designed to capture both case definitions in use and prevalence of paralysis; use of a consensus conference of experts to develop a case definition of paralysis based on the ICF rather than medical diagnostic criteria; explanation of use of the ICF framework for domains of interest to develop, cognitively test, validate and administer a brief self-report questionnaire for telephone administration on a population; and development and administration of a Paralysis Prevalence and Health Disparities Survey that used content mapping to back code items from existing national surveys to operationalize key domains.

RESULTS

ICF coding led to a national population-based survey of paralysis that produced accurate estimates of prevalence and identification of factors related to the health of people in the U.S. living with paralysis.

CONCLUSIONS

The ICF can be a useful tool for developing valid and reliable surveillance strategies targeting subgroups of individuals with functional disabilities such as people with paralysis and others.

Evaluation of post-stroke functionality based on the International Classification of Functioning, Disability, and Health: a proposal for use of assessment tools

This study aimed to identify the International Classification of Functioning, Disability, and Health categories addressed by the assessment tools commonly used in post-stroke rehabilitation and characterize patients based on its evaluation model. [Subjects and Methods] An exploratory, descriptive, cross-sectional study was conducted involving 35 individuals with chronic post-stroke hemiparesis. Handgrip strength was assessed to evaluate body functions and structures. The 10-meter gait speed test and Timed Up and Go test were administered to evaluate activity. The Stroke Specific Quality of Life scale was used to evaluate participation. Moreover, a systematic review of the literature was performed to identify studies that have associated these assessment tools with the International Classification of Functioning, Disability, and Health categories. [Results] The tools employed in this study for evaluating function addressed 63 International Classification of Functioning, Disability, and Health categories: 24 related to body functions and structures; 36 related to activity and participation; and 3 related to environmental factors. [Conclusion] The assessment tools employed in this study addressed 63 International Classification of Functioning, Disability, and Health categories and allowed a more complete evaluation of stroke survivors with hemiparesis. Use of this classification can therefore be more easily incorporated into clinical practice.

Functioning in lymphedema from the patients' perspective using the International Classification of Functioning, Disability and health (ICF) as a reference

PURPOSE

To identify and quantify meaningful concepts in lymphedema from the patients' perspectives using the International Classification of Functioning, Disability and Health (ICF).

METHODS

Six focus group interviews in five different centers were organized, audiotaped, transcribed verbatim and analyzed.

RESULTS

A total of 2681 relevant ICF linkings were performed with the focus group data, resulting in 130 different second-level categories. Of these 130 second-level categories, 41 (31.5%) categories were categorized as Body Functions, 20 (15.5%) as Body Structures, 41 (31.5%) as Activities and Participation, and 28 (21.5%) as Environmental Factors. Overall, the most important issues according to the patients were the use of hosiery and bandages, support and relationships, and the shape of structures related to movement.

CONCLUSION

Based on their experiences with lymphedema, patients reported activity limitations and participation restrictions combined with impaired body functioning. Anatomical changes (Body Structures) were also often mentioned as a problem in daily life. Environmental factors may act as a barrier or facilitator for patient functioning. The ICF provides a valuable reference to identify concepts in statements from lymphedema patients. The results of this research will be used in the development of ICF Core Sets for lymphedema.

Feasibility of Applying the Extended ICF Core Set for Stroke to Clinical Settings in Rehabilitation: A Preliminary Study

Objective

To evaluate the potential feasibility of application of the extended International Classification of Functioning, Disability and Health (ICF) Core Set for stroke.

Methods

We retrospectively reviewed the medical records of 40 stroke outpatients (>6 months after onset) admitted to the Department of Rehabilitation Medicine for comprehensive rehabilitation. Clinical information of the patients were respectively evaluated to link to the 166 second-level categories of the extended ICF Core Set for stroke.

Results

Clinical information could be linked to 111 different ICF categories, 58 categories of the body functions component, eight categories of the body structures component, 38 categories of the activities and participation component, and seven categories of the environmental factors component.

Conclusion

The body functions component might be feasible for application of the extended ICF Core Set for stroke to clinical settings. The activities and participation component and environmental factors component may not be directly applied to clinical settings without additional evaluation tools including interview and questionnaire.

Conceptualizing disability in US national surveys: application of the World Health Organization's (WHO) International Classification of Functioning, Disability, and Health (ICF) framework

PURPOSE

Disability data inform resource allocation and utilization, characterize functioning and changes over time, and provide a mechanism to monitor progress toward promoting and protecting the rights of individuals with disability. Data collection efforts, however, define and measure disability in varied ways. Our objective was to see how the content of disability measures differed in five US national surveys and over time.

METHODS

Using the WHO ICF as a conceptual framework for measuring disability, we assessed the National Health Interview Survey (NHIS), Current Population Survey (CPS), Survey of Income and Program Participation (SIPP), National Survey of SSI Children and Families (NSCF), and American Community Survey (ACS) for their content coverage of disability relative to each of the four ICF components (i.e., body functions, body structures, activities and participation, and environment). We used second-level ICF three-digit codes to classify question content into categories within each ICF component and computed the proportion of categories within each ICF component that was represented in the questions selected from these five surveys.

RESULTS

The disability measures varied across surveys and years. The NHIS captured a greater proportion of the ICF body functions and body structures components than did other surveys. The SIPP captured the most content of the ICF activities and participation component, and the NSCF contained the most content of the ICF environmental factors component.

CONCLUSIONS

This research successfully illustrated demonstrated the utility of the ICF in examining the content of disability measures in five national surveys and over time.

Developing item banks for measuring pediatric generic health-related quality of life: an application of the International Classification of Functioning, Disability and Health for Children and Youth and item response theory

The purpose of this study was to develop item banks by linking items from three pediatric health-related quality of life (HRQoL) instruments using a mixed methodology. Secondary data were collected from 469 parents of children aged 8-16 years. The International Classification of Functioning, Disability and Health-Children and Youth (ICF-CY) served as a framework to compare the concepts of items from three HRQoL instruments. The structural validity of the individual domains was examined using confirmatory factor analyses. Samejima's Graded Response Model was used to calibrate items from different instruments. The known-groups validity of each domain was examined using the status of children with special health care needs (CSHCN). Concepts represented by the items in the three instruments were linked to 24 different second-level categories of the ICF-CY. Eight item banks representing eight unidimensional domains were created based on the linkage of the concepts measured by the items of the three instruments to the ICF-CY. The HRQoL results of CSHCN in seven out of eight domains (except personality) were significantly lower compared with children without special health care needs (p<0.05). This study demonstrates a useful approach to compare the item concepts from the three instruments and to generate item banks for a pediatric population.

Cross-sectional analysis of the reporting of continuous outcome measures and clinical significance of results in randomized trials of non-pharmacological interventions

Background

Reporting the scoring details of continuous outcome measures in randomized trials allows readers to interpret the size of any effect of the intervention. This study aimed to determine, in a sample of randomized trials: 1) the completeness of reporting of scoring details for continuous outcome measures, and 2) whether trial authors comment on the clinical significance of statistically significant trial results.

Methods

A descriptive analysis of randomized trials of non-pharmacological interventions published during 2009 in the six leading general medical journals (n = 138), and which used at least one continuous outcome measure (n = 85). From each trial report, two authors independently extracted the following information about each continuous outcome measure: the reporting of its scoring details, presentation of its results, and the reporting and justification of the clinical significance of the results.

Results

Across the 84 trials, we identified 336 continuous outcome measures. A total of 146 (44%) were published measures, 12 (4%) were adapted from published measures, 5 (1%) were developed for the trial, and 173 (51%) were ‘conventional measures’ for which scoring details are not necessary (such as weight). For 57 (35%) of the 163 non-conventional outcome measures no scoring details or reference to the outcome measure were provided in the trial report. Of the 159 outcome measures with a statistically significant result, clinical significance was not mentioned for 81 (51%) and was reported without any elaboration or justification for 39 (25%) of them.

Conclusions

Scoring details of continuous outcome measures used in this sample of randomized trials of non-pharmacological interventions were incompletely reported, which hampers interpretation of a trial’s results. Complete reporting of scoring details is important when considering the clinical significance of the results. When deciding about an intervention, having this information may help clinicians in their conversations with patients about the possible benefits and harms, and their size, of the intervention.

Content verification of the EORTC QLQ-C30/EORTC QLQ-BR23 with the International Classification of Functioning, Disability and Health

PURPOSE

The aims of this study were to estimate the extent to which the content of the EORTC QLQ-C30 and EORTC QLQ-BR23 goes beyond functioning and include global feeling of well-being.

METHODS

Respectively, 21 and 13 healthcare professionals agreed to link the EORTC QLQ-C30 and EORTC QLQ-BR23 to the ICF. Mappers were asked to independently identify appropriate codes for the corresponding items of the EORTC QLQ-C30 and EORTC QLQ-BR23 following standardized linking rules and methodology. A Delphi technique was used in order to reach consensus. The threshold of agreement was 70 %. Rounds were stopped when the threshold was obtained or when it was clear that no consensus would be reached.

RESULTS

A total of 25 items out of 30 were endorsed for the EORTC QLQ-C30: 8 items were endorsed at the 4-digit level, 15 items at the 3-digit level, and 2 items reach the consensus that the items were not cover within the ICF. Only 2 items out of 23 did not reach consensus in the EORTC QLQ-BR23. Of the 21 items endorsed, 3 items were endorsed at the 5-digit level, 10 items at the 4-digit level, and 8 at the 3-digit level.

CONCLUSION

This study demonstrates that the content of the EORTC QLQ-C30 goes beyond functioning and includes global feeling of well-being and that the content of the EORTC QLQ-BR23 is related to functioning. Furthermore, linking items to the ICF framework could be an additional method to validate the content of health-related questionnaires.

Health outcome after major trauma: what are we measuring?

Importance

Trauma is a global disease and is among the leading causes of disability in the world. The importance of outcome beyond trauma survival has been recognised over the last decade. Despite this there is no internationally agreed approach for assessment of health outcome and rehabilitation of trauma patients.

Objective

To systematically examine to what extent outcomes measures evaluate health outcomes in patients with major trauma.

Data Sources

MEDLINE, EMBASE, and CINAHL (from 2006–2012) were searched for studies evaluating health outcome after traumatic injuries.

Study selection and data extraction

Studies of adult patients with injuries involving at least two body areas or organ systems were included. Information on study design, outcome measures used, sample size and outcomes were extracted. The World Health Organisation International Classification of Function, Disability and Health (ICF) were used to evaluate to what extent outcome measures captured health impacts.

Results

34 studies from 755 studies were included in the review. 38 outcome measures were identified. 21 outcome measures were used only once and only five were used in three or more studies. Only 6% of all possible health impacts were captured. Concepts related to activity and participation were the most represented but still only captured 12% of all possible concepts in this domain. Measures performed very poorly in capturing concepts related to body function (5%), functional activities (11%) and environmental factors (2%).

Conclusion

Outcome measures used in major trauma capture only a small proportion of health impacts. There is no inclusive classification for measuring disability or health outcome following trauma. The ICF may provide a useful framework for the development of a comprehensive health outcome measure for trauma care.
