Resumo(s)
Em resultado da crescente digitalização dos serviços hospitalares, a relevância do serviço de informática tem aumentado significativamente. Isto tem também contribuído para um aumento do número de trabalhadores afetos a este serviço, assim como da respetiva carga de trabalho, o que pode ter potenciado a exposição dos trabalhadores de informática a fatores de riscos ocupacionais específicos, sobretudo de natureza biomecânica e física, organizacional e psicossocial. Este relatório de estágio tem como objetivo principal descrever o trabalho realizado numa Unidade Local de Saúde pública do Norte do País, nomeadamente no que se refere ao estudo ergonómico dos postos de trabalho no Serviço de Informática desta unidade hospitalar, identificação de fatores de risco associados ao uso intensivo de equipamentos dotados de visor (EDV) e proposta de soluções preventivas inovadoras, com destaque para o desenvolvimento de uma aplicação móvel destinada à promoção de comportamentos seguros e saudáveis. A metodologia adotada combinou diferentes abordagens: observação direta das condições de trabalho e tarefas realizadas, avaliação do risco de desenvolvimento de Lesões Musculoesqueléticas Relacionados com o Trabalho (LMERT) através da aplicação do método Rapid Upper Limb Assessment (RULA) e aplicação de um questionário para a avaliação subjetiva das condições de conforto e exigências laborais. Os resultados revelaram a existência de fatores de risco relevantes, nomeadamente no que respeita à adoção de posturas incorretas, ausência de ajuste entre o mobiliário e as características dos utilizadores e requisitos das tarefas, iluminação inadequada e ausência de pausas regulares. Os resultados da aplicação do RULA revelaram níveis de risco que exigem intervenção a curto prazo em diversos postos de trabalho, confirmando a necessidade de melhorias estruturais e organizacionais. No que respeita à avaliação subjetiva, os resultados mostraram que os trabalhadores reconhecem a existência de diversos constrangimentos associados ao local e ambiente de trabalho. Os resultados obtidos enfatizam a importância de estratégias preventivas, como são aquelas baseadas em ferramentas digitais. Neste sentido, foi concebida uma proposta de aplicação móvel em língua portuguesa, orientada para a monitorização postural, pausas ativas, gamificação e disponibilização de recomendações personalizadas.
As a result of the increasing digitalization of hospital services, the relevance of the Information Technology (IT) department has risen significantly. This has also contributed to an increase in the number of workers assigned to this service, as well as in their workload, which may have enhanced IT workers’ exposure to specific occupational risk factors, particularly of a biomechanical, physical, organizational, and psychosocial nature. The main objective of this internship report is to describe the work carried out in a public Local Health Unit in the North of Portugal, specifically regarding the ergonomic assessment of workstations in the IT department of this healthcare unit, the identification of risk factors associated with the intensive use of display screen equipment (DSE), and the proposal of innovative preventive solutions, with a special focus on the development of a mobile application aimed at promoting safe and healthy behaviours. The adopted methodology combined different approaches: direct observation of working conditions and performed tasks, risk assessment of work-related musculoskeletal disorders (WMSDs) through the application of the Rapid Upper Limb Assessment (RULA) method, and the administration of a questionnaire to evaluate workers’ subjective perceptions of comfort conditions and job demands. The results revealed the existence of relevant risk factors, particularly concerning the adoption of inadequate postures, the lack of adjustment between furniture and users’ characteristics and task requirements, insufficient lighting, and the absence of regular breaks. The application of the RULA method indicated risk levels requiring short-term intervention in several workstations, confirming the need for structural and organizational improvements. Regarding the subjective assessment, the results showed that workers acknowledge the existence of various constraints associated with their workplace and work environment. The findings highlight the importance of preventive strategies, especially those supported by digital tools. In this context, a proposal was developed for a mobile application in Portuguese, designed to support postural monitoring, active breaks, gamification, and the provision of personalized recommendations.
