ABSTRACT Laboratory automation in microbiology improves productivity and reduces sample turnaround times (TATs). However, its full potential can be unlocked through the optimization of workflows by adopting lean principles. This study aimed to explore relative impact laboratory continuous improvement events (CIEs) on TATs. took place November 2020 consisted introduction WASPLab VITEK MS systems. CIEs were run May September 2021. Before conversion, processed about ~492 samples weekdays had 10 full-time equivalent (FTE) staff for a 49 samples/FTE/day. In March 2021, after automation, caseload went up ~621 while FTEs decreased 8.5, accounting 73 The hypothetical 110 samples/FTE/day following CIEs, meaning that could at point deal with increase ~935 unchanged FTEs. conversion also led an TATs all types. For vaginal swabs urine samples, median from 70.3 h [interquartile range (IQR): 63.5–93.1] 73.7 (IQR: 35.6–50.7) 48.2 44.8–67.7) 40.0 35.6–50.7), respectively. Automation alone was responsible 37.2% 75.8% TAT reduction, respectively, remaining reduction 62.8% 24.2%, achieved due CIEs. reached goals predefined management conclusion, substantially improved TATs, subsequent implementation further automation.
