Perception of the usability of Health Information Systems in Brazil

This dataset contains the data and the R code of the study described below. Title Perception of the usability of Health Information Systems in Brazil Abstract Purpose: Validate the National Usability Focused Health Information Systems Scale (NuHISS) in the Brazilian context, measure the overall assessment of these systems, and identify the factors that influence this Health Information Systems (HIS) assessment in Brazil. Method: We conducted a survey with 262 doctors and nurses from February to May 2020. To measure usability, we used the validated National Usability-focused HIS Scale (NuHISS). Findings: The results show adequate validity and reliability for the validation of the NuHISS scale in the Brazilian context. The survey indicated an overall percentage of 38.9% of users rated the system they used as a high-quality system. Still, technical quality, ease of use, and benefits explain 43.5% of the user’s overall assessment of systems. Conclusion: This study validated the NuHISS scale for the Brazilian context and therefore it will be possible to use this scale to measure the usability of the HIS of Brazilian doctors and nurses. Furthermore, the results suggest that there is dissatisfaction with the usability of the HIS systems and, for this reason, usability is a factor that those responsible for health systems must observe.本数据集包含下述研究的相关数据与R代码。 研究标题：巴西医疗信息系统可用性感知 摘要 研究目的：在巴西语境下验证以可用性为核心的国家医疗信息系统量表（National Usability Focused Health Information Systems Scale, NuHISS），评估此类医疗信息系统的整体使用评价，并识别影响巴西医疗信息系统（Health Information Systems, HIS）使用评价的相关因素。 研究方法：本研究于2020年2月至5月间面向262名医生与护士开展问卷调查。本研究采用已验证的以可用性为核心的国家医疗信息系统量表（NuHISS）对系统可用性进行测评。 研究结果：结果表明，在巴西语境下对NuHISS量表进行验证时，其具备良好的效度与信度。调查显示，共有38.9%的用户将其所使用的系统评定为高质量系统。此外，技术质量、易用性与系统收益可解释医护人员对医疗信息系统整体评价的43.5%。 研究结论：本研究完成了针对巴西语境的NuHISS量表验证工作，后续可依托该量表对巴西医护人员所使用的医疗信息系统可用性进行测评。此外，研究结果显示医护人员对巴西医疗信息系统的可用性存在不满，因此医疗系统负责人需将系统可用性作为重点关注的优化方向。
