A queue ticket system (QTS) used in an outpatient phlebotomy clinic was unable to be directly integrated with the laboratory information system (LIS). To monitor patient's waiting time and extended turnaround time (TAT) as patient-centered quality indicators for outpatient laboratory services, we developed an algorithm to integrate data between the QTS and the LIS.
Between June 1 to September 30, 2017, data files were exported from a QSYS-8000 (HION Tech, Seoul, Korea). Each calling event from the QTS data was matched to a barcode of test requests from the LIS if the following conditions were met: (1) time interval between "call time" from QTS and "barcode printing time" from LIS <90 s; (2) "Counter Number" from LIS="Counter Number" from QTS. Extended TAT was estimated as the interval between pulling the queue ticket and the reporting of the test result.
82.66%±3.14% of the barcodes from the LIS were matched to issued tickets. Median waiting time (mean±SD) was 6.5±5.3 min. Median extended TAT was 84.7±11.2 min for non-STAT and 53.0±6.4 min for STAT.
When a stand-alone QTS was used in the outpatient phlebotomy clinic, data from the QTS and the LIS were integrated using a novel algorithm we developed.
门诊采血诊所使用的排队叫号系统（QTS）无法直接与实验室信息系统（LIS）集成。为了监测患者等待时间以及作为门诊实验室服务以患者为中心的质量指标的延长周转时间（TAT），我们开发了一种算法来整合QTS和LIS之间的数据。
在2017年6月1日至9月30日期间，从QSYS - 8000（韩国首尔HION科技公司）导出数据文件。如果满足以下条件，QTS数据中的每个呼叫事件将与LIS中测试请求的条形码进行匹配：（1）QTS的“呼叫时间”与LIS的“条形码打印时间”之间的时间间隔<90秒；（2）LIS的“柜台编号”=QTS的“柜台编号”。延长TAT被估计为抽取排队叫号到报告测试结果之间的时间间隔。
LIS中的条形码有82.66%±3.14%与已发放的叫号匹配。中位等待时间（平均值±标准差）为6.5±5.3分钟。非紧急检验的中位延长TAT为84.7±11.2分钟，紧急检验为53.0±6.4分钟。
当门诊采血诊所使用独立的QTS时，我们使用开发的一种新算法整合了QTS和LIS的数据。
