Computerized alerts provided by health care information systems have been shown to enhance clinical practice. However, clinicians still override more than half of the alerts. This indicates that certain aspects of alerts need improvement to fulfill their purpose of supporting clinicians in decision making. This paper reports on a systematic review on studies evaluating alert specifications and their impact on clinicians' alert adherence. The review revealed that use of colors and icons to distinguish different alert severity levels and presenting high severity alerts in an interruptive fashion increases clinicians adherence to alert recommendations. Alert message contents that lack clinical importance or provide incorrect texts increase alert non-adherence. Few studies have yet focused on the impact of alert specifications on clinicians' adherence. A research agenda is needed on alert specifications and their impact on clinicians' adherence in order to develop alerts that truly support clinician decision making.
医疗保健信息系统提供的计算机化警报已被证明可改善临床实践。然而，临床医生仍会忽略超过一半的警报。这表明警报的某些方面需要改进，以实现其在支持临床医生决策方面的目的。本文报告了一项关于评估警报规范及其对临床医生警报遵守情况影响的研究的系统综述。该综述显示，使用颜色和图标来区分不同的警报严重程度级别，并以干扰性方式呈现高严重程度警报，可提高临床医生对警报建议的遵守情况。缺乏临床重要性或提供错误文本的警报消息内容会增加对警报的不遵守。很少有研究关注警报规范对临床医生遵守情况的影响。需要制定一项关于警报规范及其对临床医生遵守情况影响的研究议程，以便开发出真正支持临床医生决策的警报。
