Purpose

The purpose of this paper is to validate and measure the overall evaluation of electronic health record (EHR) and identify the factors that influence the health information systems (HIS) assessment in Brazil.

Design/methodology/approach

From February to May 2020, this study surveyed 262 doctors and nurses who work in hospitals and use the EHR in their workplace. This study validated the National Usability-focused HIS Scale (NuHISS) to measure usability in the Brazilian context.

Findings

The results showed adequate validity and reliability, validating the NuHISS in the Brazilian context. The survey showed that 38.9% of users rated the system as high quality. Technical quality, ease of use and benefits explained 43.5% of the user’s overall system evaluation.

Research limitations/implications

This study validated the items that measure usability of health-care systems and identified that not all usability items impact the overall evaluation of the EHR.

Practical implications

NuHISS can be a valuable tool to measure HIS usability for doctors and nurses and monitor health systems’ long-term usability among health professionals. The results suggest dissatisfaction with the usability of HIS systems, specifically the EHR in hospital units. For this reason, those responsible for health systems must observe usability. This tool enables usability monitoring to highlight information system deficiencies for public managers. Furthermore, the government can create and develop actions to improve the existing tools to support health professionals.

Social implications

From the scale validation, public managers could monitor and develop actions to foster the system’s usability, especially the system’s technical qualities – the factor that impacted the overall system evaluation.

Originality/value

To the best of the authors’ knowledge, this study is the first to validate the usability scale of EHR systems in Brazil. The results showed dissatisfaction with HIS and identified the factors that most influence the system evaluation.

巴西卫生信息系统的可用性感知：医院卫生专业人员对电子健康记录的看法

目的

本文的目的是验证和衡量电子健康记录 (EHR) 的整体评估，并确定影响巴西健康信息系统 (HIS) 评估的因素。

设计/方法/方法

从 2020 年 2 月到 2020 年 5 月，这项研究调查了 262 名在医院工作并在工作场所使用 EHR 的医生和护士。本研究验证了以国家可用性为重点的 HIS 量表 (NuHISS) 来衡量巴西背景下的可用性。

发现

结果显示了足够的有效性和可靠性，在巴西的背景下验证了 NuHISS。调查显示，38.9%的用户认为该系统质量很高。技术质量、易用性和优势解释了 43.5% 的用户整体系统评价。

研究限制/影响

本研究验证了衡量医疗保健系统可用性的项目，并确定并非所有可用性项目都会影响 EHR 的整体评估。

实际影响

NuHISS 可以成为衡量医生和护士 HIS 可用性和监测卫生系统在卫生专业人员中的长期可用性的宝贵工具。结果表明对 HIS 系统的可用性不满意，特别是医院单位的 EHR。因此，卫生系统负责人必须注意可用性。该工具支持可用性监控，以突出公共管理人员的信息系统缺陷。此外，政府可以制定和制定行动来改进现有工具以支持卫生专业人员。

社会影响

从规模验证中，公共管理人员可以监控和制定措施以促进系统的可用性，尤其是系统的技术质量——影响整个系统评估的因素。

原创性/价值

据作者所知，这项研究首次验证了巴西 EHR 系统的可用性规模。结果表明对HIS的不满，并确定了对系统评估影响最大的因素。
