Maximizing Returns: Optimizing Biochemistry Lab Performance through Six Sigma application, a Yearlong Cost-Benefit...

Area of Science:

• Clinical Laboratory Science
• Quality Management Systems
• Healthcare Economics

Background:

• Quality control (QC) validation is crucial for clinical laboratory quality management.
• Current QC practices often lead to excessive reagent and resource consumption.
• Optimizing resource utilization while maintaining high-quality results is a key challenge.

Purpose of the Study:

• To analyze the cost-benefit of implementing effective QC procedures using Six Sigma methodology.
• To quantify the financial benefits derived from optimized QC strategies.
• To reduce resource expenditure in clinical laboratory testing.

Main Methods:

• Performed Six Sigma calculations for 23 routine chemistry parameters over one year.
• Applied new Westgard sigma rules using Biorad Unity 2.0 software.
• Compared QC performance before and after implementing new sigma rules, analyzing error rates and costs.

Main Results:

• Achieved absolute annual savings of INR 750,105.27 by combining internal and external failure costs.
• Reduced internal failure costs by 50% (INR 501,808.08) and external failure costs by 47% (INR 187,102.8).
• Savings varied based on sample volume and daily QC operations.

Conclusions:

• Careful planning of clinical laboratory QC techniques can lead to significant cost reductions.
• Implementing Six Sigma methodology effectively lowers internal and external failure costs.
• Optimized QC strategies enhance prevention and appraisal cost planning activities.
