Development of a brief core set for knee dysfunction based on the International Classification of Functioning, Disability and Health: assessing construct validity and measurement potential.

BACKGROUND: The comprehensive core set for knee dysfunction was developed to classify the functioning of people with any knee dysfunction. To be used as a clinical instrument to measure the functioning of people with knee dysfunction, the construct validity of the core set still needs to be assessed. The purpose of this study was to analyze the construct validity of the comprehensive core set for knee dysfunction as an instrument to measure functioning. METHODS: A cross-sectional study with 200 participants with knee dysfunction with or without clinical diagnosis of knee pathology, with or without complaint of pain, with or without instability, and/or with or without knee movement restriction of any type. Participants were assessed using the comprehensive core set for knee dysfunction with 25 categories, the subjective form from the International Knee Documentation Committee scale, and measures of self-perceived general health and functioning. The construct validity of the core set was assessed by Rasch analysis, and the external construct validity was assessed by correlation between the score of the brief core set for knee dysfunction with the subjective form from the International Knee Documentation Committee scale, and scores of self-perception of health and functioning. RESULTS: Twelve categories were consistent with a unidimensional construct, with no difference in the response pattern for age, sex, educational level, and time of complaint. These categories were included in the brief core set for knee dysfunction. The mean score of the brief core set was 37 ± 21 points, a value classified as moderate impairment regarding functioning. Correlations with the subjective form from the International Knee Documentation Committee scale and scores of self-perception were adequate (p < 0.01; r > 0.5). CONCLUSION: The brief core set for knee dysfunction, a set with 12 categories, can be used as a clinical instrument to measure and score the functioning of people with knee dysfunction, aged between 18 and 89 years, with adequate construct validity.

Content validity of the International Classification of Functioning, Disability and Health core set for knee dysfunction: a Delphi study.

OBJECTIVE: To assess the content validity of the preliminary core set for knee dysfunction based on the opinion of experts. DESIGN: A panel of 180 experts in knee disorders or on the use of the International Classification of Functioning, Disability, and Health for musculoskeletal conditions was invited for this Delphi study. The experts gave their opinion on whether to include the categories of the preliminary core set for knee dysfunction in a more comprehensive core set, using a six-item Likert scale. Kappa coefficient was used to analyze the agreement between the experts, and a consensus of 75% among responses was considered acceptable. RESULTS: Nineteen experts participated in all rounds. Of the 24 categories from the preliminary core set for knee dysfunction, 15 remained in the comprehensive core set and one category was further detailed into three new categories. Seven new categories were included. Thus, the comprehensive core set for knee dysfunction was composed of 25 categories with an agreement of 81.5% among responses and a Kappa value of 0.63. CONCLUSION: After validation by experts, the comprehensive core set for knee dysfunction was composed of 25 categories that can be used to assess the functioning of patients with knee dysfunction.

Funcionalidade de pacientes oncológicos: um estudo transversal com o core set genérico da classificação internacional de funcionalidade, incapacidade e saúde / Functionality of oncologic patients: a cross-sectional study with the international classification of functioning, disability and health generic core set

Introdução: O câncer é considerado uma doença crônica e um dos principais problemas de saúde enfrentados pela população. Embora o tratamento possa melhorar a sobrevida dos pacientes oncológicos, os efeitos colaterais influenciam a qualidade de vida e impactam na capacidade funcional diária. Desde 2001, com a aprovação da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF), o entendimento da funcionalidade e o da incapacidade humana passaram a ser vistos sob nova dimensão. Objetivo: Classificar a funcionalidade de pacientes oncológicos em tratamento quimioterápico por meio do core set genérico da CIF. Método: Foi realizado um estudo transversal com 117 indivíduos em tratamento quimioterápico. Para classificar a funcionalidade foi aplicado o core set genérico da CIF, que possui sete categorias em três componentes da CIF. Resultados: Os maiores comprometimentos e deficiências relatados foram nas categorias: sensação de dor (69,2%); andar (61,5%); e funções emocionais (54,7%). Conclusão: Foi identificada uma amostra de pacientes oncológicos em tratamento quimioterápico com diferentes níveis de incapacidade funcional em todas as categorias classificadas.

Introduction: Cancer is considered a chronic disease and one of the main health problems faced by the population. Although treatment can improve the survival of cancer patients, side effects influence quality of life and impact on daily functional capacity. Since 2001, with the approval of the International Classification of Functioning, Disability and Health (ICF), the understanding of functionality and disability began to be seen under a new dimension. Objective: To classify the functionality of oncologic patients in chemotherapy using the ICF generic core set. Method: A cross-sectional was conducted with 117 patients in chemotherapy. To classify the functionality, the ICF generic core set was applied, which has seven categories in three ICF components. Results: The ICF categories with the highest reported impairments and disabilities were: sensation of pain (69.2%), walking (61.5%) and emotional functions (54.7%). Conclusion: The sample of cancer patients in chemotherapy showed different levels of functional disability in all classified categories.

O uso do core set da CIF para avaliação de pacientes com distúrbios cardiorrespiratórios / The use of the ICF core set for the evaluation of patients with cardiorespiratory disorders

Introdução: A Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) categoriza a saúde e deficiência do indivíduo considerando a funcionalidade e os fatores contextuais. No entanto, a CIF apresenta muitas categorias que dificultam o seu uso diário e, por isso, foram criados os core sets. Entre os diversos core sets propostos, existe um core set para condições cardiorrespiratórias pós-agudas. Objetivo: classificar os pacientes com alterações cardíacas, respiratórias e mistas, assistidos ambulatoriais por meio de um core sets para esta população, além de verificar se existem diferenças entre os grupos na aplicação deste core set. Métodos: Foram avaliados indivíduos com diagnóstico clínico de doenças cardiorrespiratórias em acompanhamento fisioterapêutico ambulatorial para reabilitação cardiopulmonar. A amostra foi dividida em três grupos: cardíacos, respiratórios e mistos. Os pacientes foram avaliados por meio da versão abreviada do core set para condições cardiorrespiratórios pós-agudas, funcionalidade, força de preensão palmar e dos músculos respiratórios. Resultados: A amostra foi composta por 67 indivíduos alocados de acordo com seu comprometimento. Verificou-se que apenas as funções de energia e impulso, cardíaca e de ingestão, estrutura do sistema respiratório e a atividade andar apresentaram respostas significativamente diferentes entres os grupos. Pacientes com distúrbios respiratórios, cardíacos e mistos apresentam perfis funcionais semelhantes, porém as categorias com diferença desse perfil foram as relacionadas ao sistema respiratório, atividades e funções relacionadas ao aumento da demanda metabólica como andar. Conclusão: Assim é possível afirmar que o core set auxilia a identificar as disfunções dos pacientes sem depender se sua disfunção é cardíaca, respiratória ou mista que pode ser uma ferramenta utilizada no meio clínico.

Introduction: The International Classification of Functioning, Disability and Health (ICF) categorizes an individual's health and disability considering functionality and contextual factors. However, the ICF has many categories that make it difficult to use daily, and that's why core sets were created. Among the various proposed core sets, there is a core set for post-acute cardiorespiratory conditions. Objective: to classify patients with cardiac, respiratory and mixed alterations assisted in outpatient clinics using a core set for this population, in addition to verifying whether there are differences between the groups in the application of this core set. Methods: Individuals with a clinical diagnosis of cardiorespiratory in outpatient physical therapy follow-up for cardiopulmonary rehabilitation diseases were evaluated. The sample was divided into three groups: cardiac, respiratory and mixed. Patients were evaluated using the abbreviated version of the core set for post-acute cardiorespiratory conditions, functionality, handgrip strength and respiratory muscles. Results: The sample consisted of 67 individuals allocated according to their commitment. It was found that only the energy and impulse, cardiac and ingestion functions, structure of the respiratory system and walking activity showed significantly different responses between the groups. Patients with respiratory, cardiac and mixed disorders have similar functional profiles, but the categories with difference in this profile were those related to the respiratory system, activities and functions related to increased metabolic demand such as walking. Conclusion: Thus, it is possible to affirm that the core set helps to identify the patients' dysfunctions without depending on whether their dysfunction is cardiac, respiratory or mixed, which can be a tool used in the clinical environment.

Using the ICF framework to evaluate the effects of environmental factors on physical disability among people with diabetes mellitus.

Objective: This study aimed to analyze the influence of environmental factors on the ICF activity-participation outcome, controlling for body function and personal factor dimensions of 75 diabetes patients. Method: Outcome measures included questionnaires on musculoskeletal pain (Nordic Questionnaire), physical and environment domains of World Health Organization Quality of Life version BRIEF (WHOQOL-brief) and clinical and personal data. Multiple linear regression with hierarchical entry of variables was used. Results: An assessment of WHOQOL-brief revealed a score of 66.6 (SD = 17.3) to physical domain and 58.8 (DP = 12.1) to environment domain. The factors associated with physical domain were lower limb pain, number of comorbidities, and environment barriers. The highest environmental barriers were financial constraints, availability of health services, deficiency of self-management, and inadequate family and social support. The final model explained 44.0% (F[12.02], p < 0.001) of variability of the physical domain. Conclusions: We confirmed the functional consequences of diabetes mellitus to be complex and multifactorial. An approach that considers the interaction between individual and environmental attributes is necessary due to the disabling nature of this health condition.

Experimentação animal e seus limites: core set e participação pública / Animal experimentation and its limits: core set and public participation

As controvérsias em ciência e tecnologia são cada vez mais reconhecidas como questões éticas e morais, e não somente técnicas. É o caso da experimentação animal, foco deste trabalho. Visando clarificar quais grupos tiveram seus interesses e reivindicações atendidos e quais foram ignorados, foi efetuada uma análise da legislação do estado de São Paulo sobre o assunto, a partir do referencial teórico dos Estudos Sociais da Ciência e Tecnologia. O estudo abordou aspectos como a relação entre a comunidade científica, a camada política e o público leigo, a autoridade da ciência e as estratégias para inclusão/exclusão de grupos. Concluiu-se que, apesar dos crescentes questionamentos sobre as consequências sociais, éticas e morais da prática científica, a ciência ainda desempenha um papel central na resolução de controvérsias, ocupando um lugar privilegiado dentro do core set...

Controversies in science and technology are increasingly recognized as ethical and moral issues, not just technical. It is the case of animal experimentation, the central issue of this work. Using the theoretical framework of Social Studies of Science and Technology, the work analyses the law of the State of São Paulo, Brazil, about animal experimentation, aiming to clarify which groups had their interests and demands met, and which were ignored. The study addressed issues such as the relationship between the scientific community, the lay public and the policy layer, the authority of science and the strategies for inclusion/exclusion of groups. It was concluded that, despite the growing doubts about the social, moral and ethical consequences of scientific practice, science still plays a central role in the resolution of controversies, occupying a privileged place within the core set...
