Improving the Workflow of Hematology and Coagulation Workstations Using a Total Laboratory Automation System.

BACKGROUND

Total Laboratory Automation (TLA) integrates pre-analytical, analytical and post-analytical processes into a seamless workflow, improving efficiency, reducing errors, and enhancing diagnostic accuracy. Despite its advantages, comprehensive TLA integration in hematology and coagulation laboratories remains challenging due to complex sample handling and instrument-specific requirements. This study evaluates the impact of TLA implementation on workflow efficiency and turnaround time (TAT) in a high-volume clinical laboratory.

METHODS

This study was conducted at Taichung Veterans General Hospital (VGHTC). Since October 2023, the laboratory has integrated hematology and coagulation analyzers with an Abbott GLP SYSTEMS TRACK.

RESULTS

The integration of TLA significantly improved workflow efficiency and reduced operational costs. TAT compliance rates for hematology and coagulation testing improved from 82.0% and 76.9% to 95.2% and 93.0%, respectively, one year after implementation. Monthly blood collection tube consumption decreased by 2,915 units, resulting in cost savings of $437 USD and reducing carbon emissions by 32 kg CO2e. The automation system eliminated manual specimen transport requirements, saving one full-time equivalent staff position.

CONCLUSIONS

Implementing TLA in hematology and coagulation testing enhances operational efficiency, reduces environmental impact, and improves diagnostic turnaround time. Future studies should focus on long-term sustainability and clinical outcomes associated with laboratory automation.
