Clinical laboratories show significant variation in diagnostic test ordering for common requests, indicating potential for unnecessary testing. New strategies are needed to encourage cost-effective laboratory test patterns and improve healthcare efficiency.

Area of Science:

  • Clinical Chemistry
  • Laboratory Medicine
  • Healthcare Management

Background:

  • Diagnostic test ordering is a cornerstone of clinical decision-making.
  • Variability in laboratory test patterns can lead to increased healthcare costs and potential overutilization of resources.

Purpose of the Study:

  • To investigate the range of clinical chemistry tests performed in response to common clinical requests.
  • To identify variations in laboratory test patterns across different clinical chemical laboratories.

Main Methods:

  • A survey was conducted across 19 clinical chemical laboratories.
  • Common clinical requests, such as 'plasma electrolytes please,' were used as prompts for the survey.

Main Results:

Related Experiment Videos

  • Significant variations in the specific tests ordered were observed among the surveyed laboratories.
  • The study identified a lack of standardized test ordering protocols for routine clinical inquiries.

    • Conclusions:

    • Laboratories share responsibility for unnecessary testing due to inconsistent test patterns.
    • Implementing new strategies is crucial to guide laboratories toward more cost-effective and evidence-based test selection.
