A dádiva de sangue constitui um elemento indispensável para o bom funcionamento dos sistemas de saúde. Porém, a garantia de reservas adequadas enfrenta obstáculos crescentes, sobretudo em territórios com baixa densidade populacional e acentuado envelhecimento demográfico, como sucede no Alentejo Central. Neste enquadramento, a Organização Mundial da Saúde tem destacado as sessões de colheita móveis como uma medida eficaz para estimular a participação dos cidadãos e assegurar a autossuficiência em componentes sanguíneos. O estudo, de caráter observacional, quantitativo e retrospetivo, analisou as dádivas de sangue registadas no Serviço de Imunohemoterapia da Unidade Local de Saúde do Alentejo Central E.P.E.(ULSAC) entre 2021 e 2024, com base em dados institucionais e no Sistema de Informação de Bancos de Sangue (SIBAS). Foram consideradas variáveis sociodemográficas (sexo e idade) e operacionais (tipo, frequência e número de dádivas), comparando colheitas fixas e móveis. Verificou-se uma redução de 35,32% nas dádivas no serviço, compensada por um aumento de 102,51% nas sessões de colheita móveis, resultando num crescimento global de 18,97%. Destaca-se o aumento superior a 900% das sessões de colheita móveis em dias úteis. Os homens mantêm-se como principais dadores (≈60%), embora as mulheres apresentem maior participação nas sessões móveis. Observou-se ainda menor presença de jovens nas colheitas no serviço, compensada por um aumento expressivo deste grupo nas sessões de colheita móveis, confirmando o seu potencial para atrair novos dadores. Os resultados alinham-se com as orientações internacionais, evidenciando que as sessões de colheita móveis têm um papel estratégico e não só logístico, mas também social, ao promoverem a solidariedade e a sensibilização comunitária. Persistem, contudo, desafios relacionados com a fidelização dos dadores, o envolvimento dos jovens e a inovação logística e tecnológica. Conclui-se que as sessões de colheita móveis são fundamentais para a sustentabilidade do sistema transfusional da ULSAC, assegurando reservas adequadas e renovação de dadores, sendo essencial o seu reforço através de campanhas direcionadas e gestão eficiente de recursos.
ABSTRACT Blood donation is essential for the proper functioning of healthcare systems. However, ensuring adequate supplies faces increasing obstacles, especially in areas with low population density and marked demographic aging, such as Central Alentejo. In this context, the World Health Organization has highlighted mobile blood donations as an effective measure to encourage citizen participation and ensure self-sufficiency in blood components. The observational, quantitative, and retrospective study analysed blood donations recorded at the ULSAC Immunohemotherapy Service between 2021 and 2024, based on institutional data and the SIBAS system. Sociodemographic (sex and age) and operational (type, frequency, and number of donations) variables were considered, comparing fixed and mobile blood donations. There was a 35.32% reduction in donations at the facility, offset by a 102.51% increase in mobile collection sessions, resulting in an overall growth of 18.97%. Of note is the over 900% increase in mobile collections on weekdays. Men remain the main donors (≈60%), although women have a greater participation in mobile sessions. A lower presence of young people in collections at the facility was also observed, offset by a significant increase in this group in mobile collections, confirming their potential to attract new donors. The results align with international guidelines, demonstrating that mobile collections play a strategic role not only logistically but also socially, by promoting solidarity and community awareness. However, challenges remain related to donor loyalty, youth engagement, and logistical and technological innovation. It is concluded that mobile blood collection sessions are essential for the sustainability of the ULSAC transfusion system, ensuring adequate donor reserves and renewal. Strengthening these resources through targeted campaigns and efficient resource management is essential.
