Evidence-based approach to setting delta check rules.

Area of Science:

• Clinical Chemistry
• Laboratory Medicine
• Quality Assurance

Background:

• Delta checks are post-analytical tools comparing sequential lab results to detect potential errors at the patient level.
• Advancements in lab automation and IT have reduced traditional delta check error types like sample misidentification.
• Selecting appropriate delta check rules is vital to balance error detection with operational efficiency.

Purpose of the Study:

• To review evidence-based approaches for optimally setting delta check rules.
• To guide laboratory practitioners in selecting rules that enhance error detection capabilities.
• To provide practical assistance for tailoring delta check rules to local needs.

Main Methods:

• Discussion of evidence-based strategies for setting delta check rules.
• Review of methods to assess real-world performance of delta check rules.
• Consideration of workflow verification for selected delta check rules.

Main Results:

• Traditional methods of setting delta check rules (professional opinion, literature) may not reflect real-world performance.
• Evidence-based approaches offer direct insights into the error detection capabilities of chosen rules.
• Optimized delta check rules can improve laboratory quality without compromising efficiency.

Conclusions:

• Setting evidence-based delta check rules is essential for effective laboratory quality management.
• Laboratories should adopt data-driven approaches to optimize delta check rule selection.
• Tailoring delta check rules to specific operational and clinical contexts is key for maximizing their utility.
