Devices are now available that are practical for point of care testing (PCT) in hospital settings. Previous studies in clinical settings, however, have failed to demonstrate a reduction in patients' length of stay (LOS) associated with the use of PCT. This randomized controlled study compared PCT with central laboratory testing in a hospital Emergency Department to assess the difference in patients' LOS. Patients randomized to PCT (n = 93) had a median stay of 3 h, 28 min (interquartile range [IR] 2:28 to 5:30), while those allocated to the central laboratory (n = 87) had a median stay of 4 h, 22 min (IR 3:04 to 5:47). The median stay associated with PCT was significantly shorter. Among patients who were destined to be discharged home, there was also a significantly shorter stay, but not among those who were destined to be admitted. It was concluded that the use of PCT can achieve significant time savings in an Emergency Department.
现在有一些设备适用于医院环境中的即时检验（PCT）。然而，之前在临床环境中的研究未能证明使用PCT与患者住院时间（LOS）的缩短有关。这项随机对照研究在医院急诊科将PCT与中心实验室检测进行比较，以评估患者住院时间的差异。随机分配到PCT组（n = 93）的患者中位住院时间为3小时28分钟（四分位间距[IR]为2:28至5:30），而分配到中心实验室组（n = 87）的患者中位住院时间为4小时22分钟（IR为3:04至5:47）。与PCT相关的中位住院时间明显更短。在注定要出院回家的患者中，住院时间也明显更短，但在注定要住院的患者中则不然。研究得出结论，在急诊科使用PCT可以显著节省时间。
