Abstract(s)
A diálise é um tratamento utilizado como principal forma de resposta à doença renal crónica
(DRC). Contudo, este procedimento está associado a problemas de sustentabilidade,
nomeadamente aos elevados consumos de água e de energia. Perante a necessidade crescente
de otimizar os recursos dos serviços de saúde, é importante criar planos que equilibrem a
eficiência técnica com um desenvolvimento mais sustentável. Neste sentido, a presente
dissertação teve como principal objetivo formular um protocolo de diálise mais sustentável
através da apresentação de soluções para melhorar a gestão e o funcionamento dos
equipamentos envolvidos neste tratamento, verificando a sua aplicabilidade.
Inicialmente, a metodologia consistiu na comparação dos consumos de água e energia antes e
após a implementação de diferentes medidas de sustentabilidade em cinco clínicas da
Diaverum. Os dados foram normalizados de modo a representar os consumos por tratamento
e garantir que as comparações entre clínicas de diferentes dimensões não fossem influenciadas
por este fator. Com base nos resultados obtidos nessas clínicas foi desenvolvido um modelo de
extrapolação que permitiu prever o efeito global destas medidas quando aplicadas a doze
clínicas na região Norte de Portugal.
As medidas abordadas ao longo da pesquisa incluem o sistema de osmose térmica, o sistema
Testomat, o sistema de reaproveitamento da água rejeitada pela osmose para usos não clínicos
e a integração de painéis fotovoltaicos.
Os resultados revelaram reduções significativas nos consumos por tratamento: até 42 % no
consumo de água e até 48 % no consumo energético das clínicas iniciais. Quando aplicadas às
restantes unidades verificou-se uma poupança média de 29 % e 33 % nos consumos de água e
energia, respetivamente, o que equivale a cerca de 22 502 m³ de água e 453 040 kWh de energia
poupados por ano.
Conclui-se que a integração de inovações tecnológicas e de procedimentos operacionais
sustentáveis minimiza significativamente o impacto ambiental da diálise, favorecendo uma
utilização mais eficiente dos recursos e a consequente sustentabilidade do setor da saúde.
Dialysis is a treatment used as the main response to chronic kidney disease (CKD). However, this procedure is associated with sustainability issues, namely high water and energy consumption. Given the growing need to optimise healthcare resources, it is important to create plans that balance technical efficiency with more sustainable development. In this sense, the main objective of this dissertation was to formulate a more sustainable dialysis protocol by presenting solutions to improve the management and operation of the equipment involved in this treatment, verifying its applicability. Initially, the methodology consisted of comparing water and energy consumption before and after the implementation of different sustainability measures in five Diaverum clinics. The data were normalised to represent consumption per treatment and ensure that comparisons between clinics of different sizes were not influenced by this factor. Based on the results obtained in these clinics, an extrapolation model was developed to predict the overall effect of these measures when applied to twelve clinics in northern Portugal. The measures addressed throughout the research include the thermal osmosis system, the Testomat system, the system for reusing water rejected by osmosis for non-clinical uses, and the integration of photovoltaic panels. The results revealed significant reductions in consumption per treatment: up to 42 % in water consumption and up to 48 % in energy consumption in the initial clinics. When applied to the remaining units, there was an average saving of 29 % and 33 % in water and energy consumption, respectively, which is equivalent to approximately 22 502 m³ of water and 453 040 kWh of energy saved per year. It can be concluded that the integration of technological innovations and sustainable operational procedures significantly minimises the environmental impact of dialysis, promoting a more efficient use of resources and the consequent sustainability of the health sector.
