Overutilization in laboratory medicine: tackling the problem with quality improvement science

Area of Science:

• Healthcare Management
• Clinical Pathology
• Medical Quality

Background:

• Overutilization of medical tests and treatments is prevalent in modern healthcare.
• Laboratory medicine faces significant challenges with unnecessary test ordering, estimated between 10-70%.

Purpose of the Study:

• To review the global problem of laboratory test overutilization, especially in developed countries.
• To explore the application of quality improvement (QI) principles in addressing this issue.

Main Methods:

• Literature review on laboratory test overutilization.
• Analysis of factors contributing to healthcare overutilization.
• Discussion of quality improvement strategies.

Main Results:

• Inappropriate laboratory test use leads to further testing, adverse events, misdiagnoses, and incorrect treatments.
• Patient harm can be physical, psychological, or financial.
• Complex factors drive overutilization, including care models and practice environments.

Conclusions:

• Quality improvement principles are essential for tackling laboratory test overutilization.
• Understanding and applying QI methods can mitigate the risks associated with unnecessary testing.
