A field-based evaluation is conducted of a Clinical Computerized Information System (CCIS). Following training, the use of the CCIS database, word processing and other programs by thirteen full-time practicing emergency physicians in two urban emergency departments of a University-associated teaching hospital was studied over a one-year period. A tracking program automatically logged frequency and duration of use by the physicians, and user satisfaction was assessed by a reliable and validated questionnaire instrument. Based on utilization data and verbal reports of these physicians, CCIS database searching was not only found to be easy-to-learn but was readily accessible during emergency shifts. Individual physicians were found to perform an average of 3.5 searches per month lasting a mean search time of 8 min. Positive notes about the CCIS system included ease-of-use, accuracy of data, accessibility of system, and value of output while negative perceptions included a lack of integration with other systems, a lack of system completeness, and a high subscription cost. It was suggested that a less costly telephone link to a high-volume Centre would be desirable in actual implementation of the system.
对一个临床计算机信息系统（CCIS）进行了基于实地的评估。在培训之后，研究了一所大学附属医院的两个城市急诊科的13名全职执业急诊医师在一年时间里对CCIS数据库、文字处理及其他程序的使用情况。一个跟踪程序自动记录医师的使用频率和时长，通过一份可靠且经过验证的问卷调查工具评估用户满意度。基于这些医师的使用数据和口头报告，发现CCIS数据库搜索不仅易于学习，而且在急诊轮班期间很容易访问。发现每位医师平均每月进行3.5次搜索，平均搜索时间为8分钟。对CCIS系统的正面评价包括易用性、数据准确性、系统可访问性和输出价值，而负面看法包括与其他系统缺乏整合、系统不完整以及订阅成本高。建议在系统的实际实施中，采用成本较低的电话链接连接到一个大容量中心是可取的。
