Development and clinical evaluation of an online automated quality control system for improving laboratory quality management

Background: We developed an efficient online automated quality control (AUTO QC) system and tested its feasibility on automatic laboratory assembly lines.Methods: AUTO QC is based on developed quality control software (Smart QC) and designed adaptable con-sumables before. We applied the system to two assembly lines in our laboratory. Using third-party quality control samples, we evaluated the impact of the online AUTO QC system on out-of-control rate, biosecurity risk, turn-around time (TAT) and cost.Results: AUTO QC significantly decreased the occurrence rate of the Westgard quality control rules 13S/22S/R4s and 12S, representing out-of-control and warning, respectively. The out-of-control rates were reduced by 58%, and the potential biosecurity risk of the samples decreased by 90%. The AUTO QC implementation also reduced the median TAT (by 7 min), the number of full-time employees and the cost of the quality control samples (by 45%). Conclusions: The total laboratory AUTO QC system can improve the quality and stability of QC testing and reduce cost.
