Estudo e proposta de catálogo para avaliação de usabilidade de sistemas de informação em saúde

Abstract

The usability assessment of Health Information Systems (HIS) is intricate due to the complex nature of the health care domain. Several studies have conducted different ways of assessing the usability of these systems. It has been found that the authors do not make clear what aspects were taken into consideration in the assessment of the user, the context of use and the task. Therefore, based on ISO 9241 and IEC 62366, a catalog was developed containing a comprehensive list of issues to be considered in a usability assessment of SIS. The catalog is composed of 137 elements and is divided into three parts (user, context and task), where each part is separated into categories that are subdivided by level of importance. Each item was justified based on the most varied aspects published in the literature on the subject. The catalog also presents for each element the parameters to be evaluated and a scale to assist the designer in the evaluation. The application of the catalog will support a better treatment of an evaluation study, potentially leading to a higher quality of SIS usability analysis studies. The catalog is an important step in building the most appropriate clinical systems.
