Abstract(s)
A Ressonância Magnética (RM) é uma ferramenta de diagnóstico poderosa e amplamente utilizada na imagiologia médica. Contudo, o processo de realização de uma RM pode ser complexo, envolvendo múltiplas etapas, tais como o agendamento dos exames, a preparação do doente, a aquisição de imagem e a sua interpretação. Este trabalho tem como objetivo analisar as tarefas do técnico superior de radiologia num exame de ressonância magnética. Trata-se de um estudo prospetivo, que inclui uma análise PERT (Program Evaluation and Review Technique) e CPM (Critical Path Method). Foi realizada uma análise e quantificação temporal das tarefas executadas em dois equipamentos de RM de 1,5 T de um hospital privado. Foram obtidos 151 exames a diferentes regiões anatómicas. No total, foram consideradas 9 tarefas, que definiram o tempo e o percurso do paciente antes, durante e após o exame de RM. Por meio desta pesquisa, foi possível verificar que, em média, um exame de RM nesta instituição em concreto, tem a duração aproximada de 42 minutos e 16 segundos. O exame com maior representatividade na amostra foi à coluna lombar (29 exames), seguido do joelho (24 exames). 35 dos 151 exames necessitaram de injeção de contraste intravenoso. No que respeita ao cumprimento da hora agendada, obteve-se que aproximadamente 72% dos exames tiveram início após a hora programada. Verificou-se que a injeção de contraste influência os tempos de tarefas como o posicionamento do doente e a remoção do doente do equipamento e encaminhamento ao vestiário. Otimizar o fluxo deste exame é essencial para melhorar a experiência do paciente e aumentar a eficiência e eficácia geral do processo de diagnóstico, bem como a gestão do equipamento, tornando-o disponível para quem dele necessita. Esta investigação permitiu aprofundar conhecimentos sobre os mecanismos de gestão da unidade de RM em estudo, que têm potencial de utilização em unidades/serviços de RM semelhantes.
ABSTRACT - Magnetic Resonance Imaging (MRI) is a powerful diagnostic tool widely used in medical imaging. However, the process of performing an MRI can be complex, involving multiple steps such as scheduling exams, preparing the patient, acquiring images, and interpreting them. This work aims to analyze the tasks of a radiographer during an MRI exam. This is a prospective study that includes a PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) analysis. Temporal analysis and quantification of the tasks performed on two 1.5 T MRI machines at a private hospital were carried out. A total of 151 exams were obtained for different anatomical regions. In total, nine tasks were considered, which defined the time and patient path before, during, and after the MRI exam. Through this research, it was possible to verify that, on average, an MRI exam at this institution lasts approximately 42 minutes and 16 seconds. The most represented exam in the sample was the lumbar spine (29 exams), followed by the knee (24 exams). 35 of the 151 exams required intravenous contrast injection. Regarding compliance with scheduled times, it was found that approximately 72% of exams started after the scheduled time. It was found that the injection of contrast influences times in tasks such as patient positioning and removal, and directing to the changing room. Optimizing the flow of this exam is essential to improve the patient experience and overall efficiency and effectiveness of the diagnostic process, as well as equipment management, making it available for those who need it. This research allowed us to gain in-depth knowledge of the management mechanisms of the MRI units under study, which have the potential to be used in similar MRI units/services.
