Análise da distribuição de tomógrafos no Brasil e avaliação do grau de utilização e usabilidade dos tomógrafos de um estabelecimento assistencial de saúde público

Abstract

Computed tomography (CT) is an important area in medicine that offers images with greater diagnostic potential, besides being used in the planning of radiotherapy. Considering the importance of the tomography scanner in the health care establishment (HCE), it is necessary to carry out an evaluative study to guarantee access to the entire population to health services in an egalitary way, beside to offer security, effectivity and satisfaction of technology's operator. Thus, the objective of this study was to verify if the distribution of tomography scanners in Brazil, in the year 2015, was in accordance with the parameters approved by Administrative Rule nº 1631, in comparison with the Municipal Human Development indexes (MHDI) of each region. Furthermore, was carried out a case study to evaluate the utilization degree and the tomography scanners's usability of a public health care establishment. As a result, it was found that there is an inequality in accessibility to tomography scanners, especially in regions where the HDI is lower. Concerning the case study, the calculated data indicated an underutilization the tomography scanners of the HCE, being the main factor that contributed to this underutilization, the failures occurrence in the tomography scanners of the Image sector and the impossibility of the using the Oncology's tomography scanners in both periods, to avoid electric overload and, consequently, energy fall in the sector. Regarding to usability measure, although the calculated data from the SUS questionnaire has been satisfatory for all tomography scanners, the heuristic evaluation performed to image sector tomography scanners's, pointed out usability problems with need to correction.
