Computer-generated management tools for the clinical pathology laboratory: I. Throughput Report

Area of Science:

• Clinical Pathology
• Laboratory Medicine
• Health Informatics

Background:

• Timely processing of stat laboratory tests is critical for patient care.
• Identifying and addressing delays in laboratory turnaround time (TAT) presents a challenge for clinical pathologists.
• Objective monitoring tools are needed to proactively manage laboratory workflow.

Purpose of the Study:

• To introduce and evaluate the Throughput Report, a computer program designed for objective measurement and monitoring of stat laboratory test TAT.
• To assess the program's ability to help clinical pathologists prospectively identify TAT issues.
• To demonstrate the impact of the Throughput Report on reducing prolonged TAT.

Main Methods:

• The Throughput Report program was developed to track key laboratory metrics.
• Key features include hourly summaries of specimen processing, TAT histograms, and overdue test lists.
• The report's utilization was assessed by monitoring changes in TAT for stat biochemical analyses.

Main Results:

• The program provides objective data on specimen flow and TAT.
• Graphic displays visualize workflow, aiding in problem identification.
• Implementation led to a near 50% reduction in stat biochemical analyses exceeding a 60-minute TAT.

Conclusions:

• The Throughput Report is an effective tool for monitoring and improving stat laboratory test TAT.
• Prospective identification of TAT problems is achievable with objective reporting.
• Graphical data visualization enhances the understanding and management of laboratory workflow efficiency.
