Optimized retrieval of test results is important to patient care and patient safety. The time during which a physician is retrieving results is a vital aspect of the diagnostic process since it is when the preliminary diagnosis is confirmed or the differential is adjusted. Better characterization of the time spent while results are displayed allows for more accurate and appropriate study of this human-computer interaction and visualization in future studies. Using screen-recording and eye-tracking software, this study's primary objective was to determine the time spent by physicians (1) displaying lab results on the screen, (2)looking at lab results, and (3) fixating on specific values in a live clinical setting. We performed in-situ eye tracking with retrospective glances and time on task measurement. A total of 6171 minutes of data were collected, with mean individual lab result screen display time of 34.7 seconds, mean viewing time of 13.9 seconds, and mean fixation time of 9.9 seconds. We found that time spent looking at specific data is only small fraction of time data is shown onscreen.
优化检查结果的检索对患者护理和患者安全至关重要。医生检索结果的时间是诊断过程的一个重要方面，因为正是在这个时候初步诊断得到确认或鉴别诊断得以调整。更好地描述显示结果时所花费的时间，有助于在未来的研究中对这种人机交互和可视化进行更准确、恰当的研究。本研究使用屏幕录制和眼动追踪软件，主要目的是确定医生在实际临床环境中（1）在屏幕上显示实验室结果、（2）查看实验室结果以及（3）注视特定值所花费的时间。我们进行了带有回顾性扫视和任务时间测量的现场眼动追踪。总共收集了6171分钟的数据，单个实验室结果的平均屏幕显示时间为34.7秒，平均查看时间为13.9秒，平均注视时间为9.9秒。我们发现，查看特定数据所花费的时间仅占数据在屏幕上显示时间的一小部分。
