A computerized system, Labstand, is described which was developed to simplify the presentation of laboratory data for the clinician. It converts data into standard units (su) on a scale of 0 to 100, identical for all tests. Conversions are based on both normal and abnormal ranges, determined from clinical experience, to allow both immediate recognition of abnormality and estimation of the degree of abnormality. This paper reports the findings of a study using this system which involved 1,412 abnormal laboratory results. Overall, both recognition and follow-up rates were higher when Labstand was used, but not to a statistically significant level. However, significantly higher follow-up rates were found when Labstand was used by residents with lower than average Internal Medicine National Board scores. In contrast, follow-up was higher when normal range laboratory reports were used by residents with higher than average scores. These findings seem consistent with the fact that use of Labstand requires minimal knowledge of ranges and biological measurement units and may indicate that the lower scoring residents have a greater need for such a new system than do the higher scoring residents.
介绍了一种名为Labstand的计算机系统，该系统旨在简化向临床医生呈现实验室数据的方式。它将数据转换为0至100范围内的标准单位（su），所有测试的标准单位相同。转换基于临床经验确定的正常范围和异常范围，以便能够立即识别异常情况并估计异常程度。本文报告了一项使用该系统的研究结果，该研究涉及1412项异常实验室结果。总体而言，使用Labstand时识别率和随访率均较高，但未达到统计学显著水平。然而，发现内科全国委员会分数低于平均水平的住院医师使用Labstand时，随访率显著更高。相比之下，分数高于平均水平的住院医师使用正常范围实验室报告时，随访率更高。这些发现似乎与以下事实一致：使用Labstand对范围和生物测量单位的知识要求最低，并且可能表明分数较低的住院医师比分数较高的住院医师更需要这样的新系统。
