APPLICABILITY OF AN ASSESSMENT MODEL FOR HEALTHCARE INFORMATION SYSTEMS IN A PUBLIC HOSPITAL

ABSTRACT Assessment processes are essential to guarantee quality and continuous improvement of software in healthcare, as they measure software attributes in their lifecycle, verify the degree of alignment between the software and its objectives and identify unpredicted events. This article analyses the use of an assessment model based on software metrics for three healthcare information systems from a public hospital that provides secondary and tertiary care in the region of Ribeirão Preto. Compliance with the metrics was investigated using questionnaires in guided interviews of the system analysts responsible for the applications. The outcomes indicate that most of the procedures specified in the model can be adopted to assess the systems that serves the organization, particularly in the attributes of compatibility, reliability, safety, portability and usability.

【摘要】评估流程是保障医疗领域软件质量与持续迭代的核心环节，其可在软件全生命周期内量化软件属性、验证软件与既定目标的契合程度，并识别未预期的异常事件。本文针对巴西里贝朗普雷图（Ribeirão Preto）地区一家提供二级与三级医疗服务的公立医院的三套医疗信息系统，分析了基于软件度量（software metrics）的评估模型的应用实践。本研究通过面向各系统责任分析师的引导式访谈与问卷调研，对各系统的度量指标符合性进行了评估。研究结果显示，该模型中规定的绝大多数流程均可用于该机构医疗信息系统的评估工作，尤其在兼容性、可靠性、安全性、可移植性与可用性等属性维度上具备良好的适配性。
