Linha de cuidado em saÃde do trabalhador: uma tecnologia para a organizaÃÃo do cuidado ao trabalhador com LER/DORT / Line in health care worker: a technology for the organisation of the worker with caution workers with repetitive strain injuries and work-related musculoskeletal disorders

AmÃlia Romana Almeida Torres 26 April 2013 (has links)
O presente estudo nasce da necessidade de melhorar a integralidade da atenÃÃo à saÃde dos trabalhadores, destacando o trabalhador com lesÃes por esforÃos repetitivos e distÃrbios osteomusculares relacionados ao trabalho - LER/DORT. Assim tivemos como objetivo construir participativamente uma linha de cuidado integral para o trabalhador com LER/DORT no Ãmbito do SUS a partir da experiÃncia dos profissionais, gestores e usuÃrios que compÃem as redes de atenÃÃo à saÃde. Desenvolvida no municÃpio de Sobral- CearÃ, esta pesquisa à de natureza qualitativa do tipo exploratÃria. A pesquisa aÃÃo foi a metodologia de escolha por constitui-se como uma metodologia que visa à aÃÃo e promove a capacidade de transformaÃÃo da realidade pelos sujeitos da pesquisa. Para tal, utilizamos a pesquisa em grupo, onde os participantes, profissionais das redes de atenÃÃo à saÃde de Sobral, foram os responsÃveis pela construÃÃo da linha de cuidado em um processo que levou à formulaÃÃo, dos fluxos e atribuiÃÃes que os prÃprios participantes da pesquisa e seus pares deverÃo desenvolver nos serviÃos em que trabalham com o objetivo de promover a integralidade da atenÃÃo à saÃde do trabalhador. Ressaltamos que estas aÃÃes da linha de cuidado foram construÃdas no ano de 2012 coletivamente, apÃs quatro encontros do grupo. O primeiro encontro foi para debater sobre integralidade e definir as aÃÃes prioritÃrias apontadas pelo grupo, o segundo encontro foi uma oficina que teve como objetivo construir o fluxo da linha de cuidado, o terceiro encontro a segunda oficina que teve como objetivo definir as atribuiÃÃes dos profissionais dos serviÃos que atendem o trabalhador, e o quarto encontro, e Ãltima oficina, tiveram como objetivos apresentar o fluxo construÃdo pelo grupo e validar as atribuiÃÃes da rede de serviÃos que atende o trabalhador com LER/DORT. Como mÃtodo de tratamento dos dados obtidos utilizamos a anÃlise do discurso. Os resultados apontam que trabalhadores com a doenÃa podem buscar diversos pontos da rede de atenÃÃo, dentre eles serviÃos da AtenÃÃo Primaria a SaÃde, da AtenÃÃo Ambulatorial Especializada, da AtenÃÃo Hospitalar e da UrgÃncia e EmergÃncia. Surgiram apÃs a validaÃÃo 36 atribuiÃÃes para os profissionais. As atribuiÃÃes identificadas incluÃram aÃÃes promocionais, preventivas, curativas e de reabilitaÃÃo. Ressaltamos que para construir a linha de cuidado pensamos na necessidade do trabalhador como o aspecto central para seu fluxo de atendimento e assistÃncia. Dessa forma, a linha de cuidado proposta demonstra uma possibilidade da garantia da integralidade relacionada à organizaÃÃo dos serviÃos de saÃde, mostrando o caminho a ser percorrido por um usuÃrio, desde a APS e passando por diferentes serviÃos na busca de um leque de cuidados necessÃrios para resolver seu problema de saÃde. Para o funcionamento da linha de cuidado proposta à necessÃrio à existÃncia de um trabalho compartilhado entre os profissionais da APS e os demais serviÃos de saÃde. Nesse processo, alÃm da construÃÃo e pactuaÃÃo do fluxo da atenÃÃo, à necessÃrio a elaboraÃÃo de estratÃgias para efetivar esse caminho a ser percorrido pelo trabalhador na rede de atenÃÃo, estabelecer e negociar responsabilidades para garantir a qualidade e continuidade do cuidado.

Validade fatorial do Maslach Burnout Inventory-Human Services Survey (MBI-HSS) em uma amostra brasileira de auxiliares de enfermagem de um hospital universitário: influência da depressão / Factorial validity of the Maslach Burnout inventory - human services survey (MBI-HSS) among Brazilian nurse assistants of a university hospital: the influence of depression

Telma Ramos Trigo 18 February 2011 (has links)
A Síndrome de Burnout entre os profissionais da área da saúde vem sendo estudada em vários países e sua associação com transtornos depressivos tem sido relatada por vários estudos. Os resultados indicam validade para o burnout, diferenciando-o da depressão e por outro lado, associação dos índices de burnout e a sintomatologia depressiva. O Maslach Burnout Inventory-Human Service Survey (MBI-HSS) é o instrumento mais utilizado para avaliar o burnout. A estrutura de três fatores do MBI tem sido confirmada em várias amostras de diversos países. Entretanto, não encontramos estudos investigando a influência da depressão nas características psicométricas do MBI-HSS. Portanto, neste estudo, investigamos a validade do MBI-HSS em uma amostra de 521 auxiliares de enfermagem de um hospital universitário utilizando a análise fatorial exploratória, análise fatorial confirmatória e consistência interna pelo alfa de Cronbach. A amostra total foi dividida em um grupo com depressão maior e outro sem depressão maior. Tanto a amostra total, quanto as subamostras apresentaram elevados valores de alfa de Cronbach para a subescala de esgotamento emocional e valores intermediários para as subescalas de realização pessoal e de despersonalização. A análise do gráfico Scree plot, diferente da análise fatorial exploratória sem fixar os fatores, indicou a solução de três fatores, como na versão original da MBI-HSS. Fixando-se em três fatores, a análise fatorial exploratória revelou maior carga fatorial em Esgotamento Emocional (EE) de dois itens de Despersonalização (DE) na subamostra com depressão maior, mas não na subamostra sem depressão maior. Diferentemente, os itens 6 e 16 de EE apresentaram maior carga fatorial em DE na subamostra sem depressão mas não a amostra com depressão. Nossos resultados indicam que a presença de depressão maior pode influenciar as propriedades psicométricas da MBI-HSS. Sugerimos que pesquisadores considerem a avaliação da validade da MBI-HSS na amostra em questão anteriormente ao uso do MBI-HSS, incluindo a avaliação dos indivíduos com e sem depressão separadamente. / The burnout syndrome among health professionals has been studied in several countries and its association with depressive disorders have been reported by several studies. The results indicate validity for burnout, differentiating it from depression and on the other hand, association between burnout and depressive symptomatology. The Maslach Burnout Inventory-Human Service Survey (MBI-HSS) has been the most used instrument to evaluate burnout. The three-factor structure of the MBI has been confirmed in several samples from different countries. However, we did not find studies investigating the influence of depression on the psychometric characteristics of the MBI-HSS. Therefore, we investigated the validity of the MBI-HSS in a sample of 521 nursing assistants in a university hospital using exploratory factor analysis, confirmatory factor analysis and internal consistency (Cronbachs alpha coefficient). The total sample was divided into a group with major depression and one without major depression. Both the total sample and the subsamples showed high values of Cronbach\'s alpha for the subscale of emotional exhaustion and intermediate values for the subscales of personal accomplishment and depersonalization. The Scree plot analysis, unlike exploratory factor analysis without fixing the factors, indicated the three-factor solution, as in the original MBI-HSS. Settling into three factors, the exploratory factor analysis revealed the highest load factor in Emotional Exhaustion (EE) of two items in the subsample of Depersonalization (DE) with major depression but not in the subsample without major depression. In contrast, items 6 and 16 of EE had higher factor loading in DE in the subsample without depression but not in the sample with depression. Our results indicate that the presence of major depression may influence the psychometric properties of the MBI-HSS. We suggest that researchers consider the evaluation of the validity of the MBI-HSS in the sample prior to the use of the MBI-HSS, including assessment of individuals with and without depression separately

Arbetsrelaterad stress bland enhetschefer. : En kvantitativ studie om hur olika stressfaktorer påverkar upplevelsen av arbetsrelaterad stress för enhetschefer inom kommunal äldre- och funktionshinderomsorg. / Work-related stress among middle managers in social services.

Persson, Julia, Sandoval, Bianca January 2019 (has links)
Enhetschefer är benämningen på den yrkesverksamma grupp som ansvarar för verksamheter som drivs enligt socialtjänstlagen och lagen om stöd och service till vissa funktionshindrade. De befinner sig i en politiskt styrd organisation med socialnämnden som uppdragsgivare. Enhetschefer är identifierade som en yrkesverksam grupp med hög arbetsbelastning och högre risk att utsättas för stress, i jämförelse med andra yrkesgrupper i ledande position. Syftet med studien är att undersöka hur olika stressfaktorer bidrar till upplevelsen av arbetsrelaterad stress hos enhetschefer inom kommunal äldre- och funktionshinderomsorg. Metodvalet är en kvantitativ enkätundersökning med syfte i att nå ut till fler personer och på så sätt få en bred överblick av enhetschefernas arbetssituation. Studien har genomförts i en medelstor svensk kommun där samtliga enhetschefer inom kommunal äldre- och funktionshinderomsorg valts ut. Av resultatet framkommer att de faktorer som i störst utsträckning bidrar till upplevd arbetsrelaterad stress, är för hög arbetsbelastning i förhållande till arbetstiden samt  bristande möjlighet att uppfylla önskemål från brukare. / Middle managers is the name of the professional group who is responsible for institutions that are run by the Social Service Act and Act concerning Support and Service for Persons with Certain Functional impairments. They work in a politically controlled organization with the municipal social welfare committee as the outsourcer. Middle managers are identified as a profession with a high workload and a higher risk of being exposed to stress, in comparison with other occupational groups with a leading position. The aim of the study is to examine how various stressors contribute to work-related stress. The method is a quantitative survey with the aim of reaching out to more people and to get a larger overview of the middle managers work situation. The study has been carried out in a medium-sized Swedish municipality, where all middle managers in municipal elderly and disability care were selected. The result shows that the stressors that contribute most to work-related stress are the high workload in relation to working time and a lack of opportunity to fulfill the client’s wishes.

Perícia ou imperícia: laudos da justiça do trabalho sobre LER/Dort / Expertise or malpractice in Labour Justice on RSI [Thesis]. São Paulo (BR): Faculdade de Saúde Pública da Universidade de São Paulo

Maeno, Maria 14 March 2018 (has links)
Introdução: O Código de Processo Civil determina que nos processos judiciais em que a matéria depender de conhecimento técnico ou científico, o juiz será assistido por perito, que produzirá um laudo. Foram analisados 83 laudos de processos judiciais do Tribunal Regional do Trabalho da 2ª Região (TRT-2), referentes a reclamantes com Lesões por Esforços Repetitivos ou Distúrbios Osteomusculares Relacionados ao Trabalho (LER/Dort), que abrangem afecções crônicas do sistema musculoesquelético de origem ocupacional e são decorrentes, dentre outros motivos, da execução de movimentos repetitivos por tempo prolongado e sobrecarga estática, sem que haja tempo para uma recuperação fisiológica. Deveriam abordar os vários aspectos do adoecimento para auxiliar a decisão judicial quanto à existência de agravo à saúde relacionado ao trabalho, assim como sua extensão e repercussões sobre a vida e capacidade laboral do trabalhador. Objetivos: Identificar e analisar, nos laudos, conceitos sobre adoecimento ocupacional e incapacidade laboral, bem como as principais linhas de argumentação, para a descaracterização do nexo causal nos casos em que havia nexo causal presumido pelo critério epidemiológico. Material e método: O material de estudo (83 laudos) foi buscado dentre os processos arquivados no período de 2012 a 2016 na Coordenadoria de Gestão de Arquivo do TRT-2, que abrange 30 municípios da região metropolitana de São Paulo e Baixada Santista. Atributos associados aos grandes temas da pesquisa foram codificados com o objetivo de melhor sistematização para uma análise de conteúdo. Resultados: Os laudos periciais foram elaborados, na sua quase totalidade por médicos, dentre os quais 56 (67,47%) médicos do trabalho, 13 (15,66%) médicos sem especificação de especialidade, 9 (10,84%) médicos com especialização em perícia ou legistas e 4 ortopedistas (4,82%). Um deles (1,21%) foi elaborado por fisioterapeuta. Do total de laudos, 25 (30,12%) não tinham quaisquer informações sobre o processo de adoecimento e apenas 23 (27,71%) contemplaram uma história clínica abrangente. Em 34 (40,96%) não havia qualquer informação sobre as características da atividade de trabalho e em 30 (36,15%) havia a citação de alguns aspectos biomecânicos. Apenas 19 (22,89%) apresentaram uma análise da atividade de trabalho, incluindo aspectos biomecânicos e organizacionais. Nenhum laudo continha uma análise da incapacidade para o trabalho de forma ampla, sendo que em 50 laudos (60,24%), o perito considerou apenas o diagnóstico para se pronunciar sobre a incapacidade. Do total dos laudos, apenas 13 (15,66%) utilizaram o conceito de multicausalidade e 12 (14,46%) o de concausalidade. Dos 15 laudos com nexo causal presumido pelo critério epidemiológico, descaracterizados no caráter ocupacional na perícia, nenhum continha uma análise da atividade de trabalho, embora 9 deles tenham utilizado argumentos biomecânicos, 8 tenham utilizado o argumento de que se tratava de doença degenerativa e 3 de que o quadro era de fibromialgia não ocupacional. Foram discutidos conceitos de adoecimento ocupacional, nexo causal e incapacidade, além da relação de desigualdade, presenteísmo, individualização do adoecimento e culpabilização. Conclusão: A maioria dos laudos periciais peca pela falta de consistência conceitual, metodológica e argumentos fundamentados, deixando lacunas na área clínica, na análise da atividade de trabalho e na avaliação de incapacidade. / Introduction: The Civil Code Procedure determines that in judicial proceedings in which the matter depends on technical or scientific knowledge, the judge will be assisted by experts, who will produce a forensic report. A total of 83 reports, from the Regional Labor Court of the 2nd Region (TRT-2), were analysed, concerning claimants suffering from Repetitive Strain Injury or Work-Related Musculoskeletal Disorders (RSI/WRMD), which include occupational chronic conditions of the musculoskeletal system, that are due, among other reason to the execution of repetitive movements for a prolonged time and static overload without pause foa a physiological recoevery. They should address the various aspects of illness in order to assist the judge in his decision regarding the existence of as aggravated health related to work, as well as its extent and repercussions on the life and work capacity of the worker. Objectives: To identify and analyse concepts about occupational illness and disability to work, expressed in the reports, as well as the main lines of argument, for the de-characterization of the causal nexus in cases where there was causal nexus presumed by the epidemiological criterion. Material and method: The study material was searched from the archived processes from 2012 to 2016 in the File Management Coordination of TRT-2, which covers 30 municipalities in the metropolitan region of São Paulo and Baixada Santista. Attributes associated with the major themes of the research were codified with the aim of better systematization for a content analysis. Results: The expert reports were elaborated almost entirely by physicians, among them 56 (67.47%) occupational physicians, 13 (15.66%) doctors without a declared specialty, 9 (10.84%), forensic doctors, 4 orthopedists (4,82%). One of the reports (1.21%) was elaborated by a physiotherapist. Of the total reports, 25 (30.12%) did not have information about the illness process and only 23 (27.71%) contemplated a comprehensive medical history. In 34 (40.96%) there was no information about the characteristics of the work activity and in 30 (36.15%) there were citation of some biomechanical aspects. Only 19 (22.89%) presented an analysis of the work activity, including biomechanical and organizational aspects. No report contained an embrancing analysis of disability to work comprehensively, and in 60.24% of them, the expert considered only the diagnosis to pronounce on the disability. Of the total reports, only 13 (15.66%) used the concept of multicausality and 12 (14.46%) the concept of concausality. Of the 15 reports with a presumed causal nexus by the epidemiological criterion, which were not characterized in the occupational character, none contained an analysis of the work activity, although 9 of the 15 reports used biomechanical arguments to de-characterize the occupational character, 8 used the argument that it was degenerative disease and 3 that the condition was non-occupational fibromyalgia. Concepts of occupational illness, causal nexus and disability were discussed, as well as the relationship of inequality, presenteism, individualization of illness and blame. Conclusions: Most of the expert reports are lacking in conceptual, methodological and reasoned arguments, leaving relevant gaps in the clinical area, in the analysis of the work activities and in the assessment of disability.

Job demands-resources theory, health and well-being in South Africa / Leon Tielman de Beer

De Beer, Leon Tielman January 2012 (has links)
Work stress has a substantial impact on employees, organisations and economies; especially in the fragile economic environment since the ‘Great Recession’ of 2008; which has seen employment levels drop and employees willing to endure more stress at work to avoid retrenchment. These impacts include serious health and financial consequences. Attempts should therefore be made to effectively manage and address work stress to lessen these dire consequences. Many models have been developed and theorised to assist in explaining work stress, the pinnacle of these being the job demands-resources (JD-R) model. In JD-R theory, the dual process explains that work-related well-being follows the following processes: An energetic, also called the health impairment process, in which job demands leads to ill health outcomes through burnout; and then a motivational process which presents that job resources leads to positive organisational outcomes, e.g. organisational commitment, through engagement. The main objectives of this research were 1) to investigate a JD-R model in a large South African sample with a categorical estimator; 2) to investigate the reversed causal hypotheses of burnout and engagement in job demands-resources theory over time; 3) to investigate the likelihood of reporting treatment for health conditions based on burnout and engagement, and 4) to investigate the link between burnout and objective financial outcomes, i.e. by medical aid provider expenditure. To achieve the first objective a cross-sectional design was used (n = 15 633) covering numerous sectors in South Africa. A dual process model was specified with job demands (work overload) leading to ill health through burnout, and job resources (colleague and supervisor support, communication, growth opportunities and role clarity) leading to organisational commitment through engagement. Results of structural equation modelling indicated that the proposed JD-R model was a good fit to the sample. Furthermore, burnout was found to mediate the relationship between job demands and ill health with a medium effect. Engagement was found to mediate the relationship between job resources and organisational commitment with a large effect. The second objective, concerning reversed causality, was achieved with a longitudinal design (n = 593). The hypothesized model included burnout and engagement at time one, and at time two work overload as indicator of job demands, and colleague and supervisor support, communication, growth opportunities and role clarity as indicators of job resources. Results indicated that burnout had a significant negative reversed causal effect to supervisor support and colleague support. Engagement showed only one significant result, i.e. a small negative reversed causal relationship with supervisor support. To achieve the third objective, a cross-sectional design was used (n = 7 895). Results for logistic regression analyses showed that an increase in burnout was associated with a significant increase in the estimated odds for reporting an affirmative answer for receiving treatment for any of the health conditions, i.e. cardiovascular conditions, cholesterol, depression, diabetes, hypertension and irritable bowel syndrome. In contrast, an increase in engagement was associated with a decrease in affirmative reporting for cardiovascular conditions, cholesterol and depression; but not for diabetes, hypertension or irritable bowel syndrome. Addressing the link between burnout and financial outcomes was the fourth objective; and met with a cross-sectional design (n = 3 182). Participants were divided into a high and low burnout group based on the comorbidity of exhaustion and cynicism Analysis of covariance (ANCOVA) was implemented, controlling for age and gender, to investigate the difference in medical aid provider expenditure of the two groups. Results revealed that expenditure in the high burnout group was consistently more in all cases, compared to the low burnout group. By way of conclusion, the implications of the research were discussed and recommendations for managers and for future research were made. / Thesis (PhD (Industrial Psychology))--North-West University, Potchefstroom Campus, 2013

Repetitive strain injury among South African employees : prevalence and the relationship with exhaustion and work engagement / Gillian Schultz

Schultz, Gillian January 2010 (has links)
The work environment of today is synonymous with stress, fatigue and exhaustion. As a result, the incidence of workplace injury and disease is increasingly commonplace. Repetitive Strain Injury (RSI) is the most common form of work–related ill–health. If the symptoms are not recognised and addressed early, serious and more chronic manifestations of the symptoms can emerge, subsequently affecting the quality and duration of a persons' working life. RSI also has significant implications for organisations in terms of lost productivity, drops in work quality and costly compensation claims. Although there is ongoing international research available concerning workplace injury and disease to inform business and the employee, there is less comprehensive and regularly updated research within the South African context. Considering employers can be held accountable for diseases that have arisen out of and in the course of an individual's employment, this research adds value in ascertaining the magnitude of RSI in South Africa. Bearing in mind international research has expanded its focus to include the potential influence of ergonomic and psychosocial factors in the development of RSI, it has become necessary to consider additional factors that may play a role in the development and maintenance of RSI. The objectives of this study were to 1) determine the frequency of RSI experienced amongst South African employees; 2) examine the frequency of RSI across three well–being groups; and 3) identify whether there are significant differences across the three well–being groups. An availability sample (N = 15 664) was utilised to determine the frequency of experience of RSI in a sample of South African employees. Frequencies were used to determine the incidence of RSI symptoms for the total sample. Participants were then selected into groups based on their experience of vitality, work devotion and exhaustion (n = 4 411) in order to determine the frequency of RSI experienced for three well–being groups. ANOVA was used to determine if there were significant RSI differences between these three well–being groups. The results of this study highlight that RSI is prevalent amongst the South African population. Of those participants who responded 'sometimes' and 'frequently' (experiencing RSI), 47% indicated experiencing neck, shoulder and back discomfort, followed by 42% reporting eyestrain, and 24% muscle stiffness. These results are comparable with international statistics, indicating that a relatively large percentage of South African employees experience RSI. The results further showed that the frequency of experience of RSI symptoms does differ across the three well–being groups. It is evident that RSI is more prevalent in the well–being group that demonstrates vital exhaustion when compared to those who are work engaged yet exhausted, and those who are truly work engaged. Secondly, the results clearly revealed statistically significant differences between all of these groups. Thus, those individuals who are vitally exhausted experience significantly greater RSI symptoms than those who are truly work engaged or engaged with exhaustion. In addition, those individuals who are work engaged with exhaustion demonstrate significantly more RSI symptoms than those who are truly work engaged. Thus, this study suggests the potential role of exhaustion in the development of RSI. Recommendations were made for the organisation and for future research. / Thesis (M.Com.
