Using the capabilities of the HELP medical information system at LDS Hospital, a Computerized Laboratory Alerting System (CLAS) was developed. CLAS monitors and alerts for the presence of life-threatening conditions in hospitalized patients which are indicated by laboratory test results. Alerts are posted on computer terminals on the hospital's nursing divisions, where they are reviewed and acknowledged by hospital staff so that appropriate treatment can be rapidly instituted. CLAS was evaluated to determine its effectiveness in relaying alerts to the clinical staff, and improvements were made to develop an effective user interface. Initial average alert response times on nursing divisions ranged from 5.1 to 58.2 hr. The average alert response time dropped to 3.6 hr when alert review was integrated with laboratory result review, and to 0.1 hr after installation of a flashing light to notify hospital staff of the presence of new alerts.
利用LDS医院HELP医学信息系统的功能，开发了一个计算机化实验室警报系统（CLAS）。CLAS监测住院患者中由实验室检查结果表明的危及生命状况的存在并发出警报。警报会发布在医院护理部门的计算机终端上，医院工作人员会在那里查看并确认警报，以便能够迅速采取适当的治疗措施。对CLAS进行了评估，以确定其向临床工作人员传达警报的有效性，并进行了改进以开发有效的用户界面。护理部门最初的平均警报响应时间为5.1至58.2小时。当警报审查与实验室结果审查相结合时，平均警报响应时间降至3.6小时，在安装了闪烁灯以通知医院工作人员有新警报后，平均警报响应时间降至0.1小时。
