Background: To further improve workflow efficiency, our laboratory implemented a total laboratory automation (TLA) system that connected our preanalytic processing system with various testing (hematology, coagulation, and chemistry).
Methods: Detailed time and motion studies were performed to create process flow maps before and after TLA. The before maps identified opportunities for workflow improvements. We used postimplementation studies to quantify efficiency gains.
Results: The implementation of our TLA system resulted in 86% fewer discrete processing steps in specimen handling, even when starting from a partially automated laboratory. Instrument consolidation reduced the testing footprint by 45% and reduced the number of testing personnel by 2.5 full-time employees (FTEs). An 82% reduction in hands-on time associated with add-on processes was achieved. Combining STAT and outreach work on the testing system did not impact turnaround time.
Conclusions: With careful planning, a TLA system can effectively optimize laboratory processes and efficiency.
