Laboratory test turnaround times (TATs) for emergency department patients were studied in 722 institutions using Q-Probes, a quality improvement program of the College of American Pathologists. The medians of the TATs required by 2763 clinicians were 10 minutes for PO2, 20 minutes for hemoglobin, and 30 minutes for potassium and glucose measurements. Surgeons had the shortest TAT requirements for hemoglobin, potassium, and glucose measurements, whereas emergency department physicians had the shortest requirements for PO2. The measured TATs of most hemoglobin and potassium determinations did not meet clinician goals. In contrast to laboratorians, the majority of clinicians defined a TAT start time as test ordering, and a TAT ending time as result reporting. We recommend laboratorians and clinicians mutually agree on the definition of TAT, jointly develop timeliness goals, and together improve TAT performance to fulfill these goals.
利用美国病理学家学会的质量改进项目Q-Probes，在722家机构中对急诊科患者的实验室检查周转时间（TAT）进行了研究。2763名临床医生所需TAT的中位数为：氧分压测定10分钟，血红蛋白测定20分钟，钾和葡萄糖测定30分钟。外科医生对血红蛋白、钾和葡萄糖测定的TAT要求最短，而急诊科医生对氧分压测定的要求最短。大多数血红蛋白和钾测定的实测TAT未达到临床医生的目标。与检验人员不同，大多数临床医生将TAT开始时间定义为下达检验医嘱，将TAT结束时间定义为报告结果。我们建议检验人员和临床医生就TAT的定义达成共识，共同制定及时性目标，并共同提高TAT绩效以实现这些目标。
