Instrument traceability: Optimisation of Datamatrix readers by an experimental design

Area of Science:

• Medical Device Traceability
• Industrial Engineering
• Operations Management

Background:

• Implementing individual-level instrument traceability using Data Matrix barcodes faced challenges with reader effectiveness.
• Ineffective barcode reading slowed down the medical procedure tray repackaging process and caused operator reluctance.
• This hindered the efficient deployment of Data Matrix technology in healthcare settings.

Purpose of the Study:

• To optimize the performance of Data Matrix readers for individual instrument traceability.
• To identify key parameters influencing reader performance and determine their optimal settings.
• To overcome bottlenecks in the medical procedure tray repackaging stage.

Main Methods:

• Utilized the Taguchi method for experimental design to efficiently identify influential parameters.
• Conducted a limited number of trials to determine optimal settings for reader performance.
• Focused on improving the reading time of instruments with Data Matrix barcodes.

Main Results:

• Achieved an 81% reduction in instrument reading time.
• Optimized reader performance using lean production resources.
• Successfully addressed operator reluctance and improved process efficiency.

Conclusions:

• The Taguchi method effectively optimized Data Matrix reader performance for instrument traceability.
• Significant improvements in reading time and efficiency were realized, enabling continued implementation.
• Enhanced traceability processes led to increased satisfaction among medical staff and improved operational workflow.
