临床信息系统改善护理和患者治疗效果的有效性取决于人为因素，包括系统可用性、组织工作流程和用户满意度。研究居民、家庭成员和临床医生在多大程度上发现用于监测老年人活动水平的传感器数据接口在独立生活环境中可用和有用。三名独立专家评审员进行了初步启发式评估。随后，20名最终用户（5名居民、5名家庭成员、5名注册护士和5名医生）参与了评估。在评估过程中，每个参与者都被要求完成来自三名居民的三个场景。 Morae 记录器软件用于捕获用户交互过程中的数据。启发式评估提出了 26 条界面改进建议；这些被分类在内容、审美情趣、导航和建筑等标题下，这些标题是从启发式结果中得出的。老年居民完成场景的总时间比其他用户长得多。家庭成员花在完成场景上的时间比临床医生多，但比居民少。老年居民和家庭成员难以解释临床数据和图表，经历信息超载，并且不理解术语。所有用户都发现传感器数据接口对于识别不断变化的居民活动很有用。老年用户有特殊的需求，在为他们设计临床界面时应满足这些需求，特别是与健康信息一样重要的信息。在实施之前，应要求评估用户与临床信息系统交互过程中的人为因素。
Effectiveness of clinical information systems to improve nursing and patient outcomes depends on human factors including system usability, organizational workflow, and user satisfaction. To examine to what extent residents, family members, and clinicians find a sensor data interface used to monitor elder activity levels usable and useful in an independent living setting. Three independent expert reviewers conducted an initial heuristic evaluation. Subsequently, 20 end users (5 residents, 5 family members, 5 registered nurses, and 5 physicians) participated in the evaluation. During the evaluation each participant was asked to complete three scenarios taken from three residents. Morae recorder software was used to capture data during the user interactions. The heuristic evaluation resulted in 26 recommendations for interface improvement; these were classified under the headings content, aesthetic appeal, navigation, and architecture, which were derived from heuristic results. Total time for elderly residents to complete scenarios was much greater than for other users. Family members spent more time than clinicians, but less time than residents to complete scenarios. Elder residents and family members had difficulty interpreting clinical data and graphs, experienced information overload, and did not understand terminology. All users found the sensor data interface useful for identifying changing resident activities. Older adult users have special needs that should be addressed when designing clinical interfaces for them, especially information as important as health information. Evaluating human factors during user interactions with clinical information systems should be a requirement before implementation.
