We developed a system of computer programs to gather and then display data on turnaround time for stat tests. The data were those generated by the testing process itself so that no additional data entry was necessary. The system provided daily as well as longitudinal data for statistical process control implemented in the laboratory. The median and 90th percentile turnaround times were calculated for high-volume tests (complete blood cell count and Chem6 [six chemical serum component concentrations, ie, sodium, potassium, chloride, carbon dioxide, glucose, and urea nitrogen]), and a graphic display was automatically generated. These parameters and visual aids permitted evaluation of stat processing in the laboratory. The impact of management decisions on the stat process could be measured. Intralaboratory processing procedures were modified, and phlebotomy personnel were repositioned. Our various measurements showed which decisions improved stat turnaround time.
我们开发了一套计算机程序系统，用于收集并显示急诊检验周转时间的数据。这些数据由检验过程本身生成，因此无需额外的数据录入。该系统为实验室实施的统计过程控制提供每日数据以及纵向数据。针对大量检验项目（全血细胞计数和生化六项[六种血清化学成分浓度，即钠、钾、氯、二氧化碳、葡萄糖和尿素氮]）计算了中位数和第90百分位数周转时间，并自动生成图形显示。这些参数和直观工具有助于评估实验室中的急诊检验处理情况。可以衡量管理决策对急诊检验流程的影响。实验室内部的处理程序得到了修改，采血人员也进行了重新安排。我们的各项测量结果显示了哪些决策改善了急诊检验周转时间。
