Summary

Routine coagulation testing before surgery is not clinically valuable for predicting bleeding risk. Clinical assessment and selective lab testing are more effective and cost-efficient, avoiding false reassurance from inaccurate tests.

Area of Science:

  • Medical Diagnostics
  • Clinical Pathology
  • Surgical Hemostasis

Background:

  • Coagulation tests are routinely used before invasive procedures, assuming they predict bleeding risk.
  • The clinical utility of these standard tests in surgical and medical settings is often unquestioned.

Purpose of the Study:

  • To systematically review the literature on the value of routine coagulation testing in predicting bleeding risk.
  • To clarify the limitations of first-line coagulation tests in clinical practice.

Main Methods:

  • Systematic literature review.
  • Analysis of studies evaluating the predictive value of routine coagulation tests for bleeding.

Main Results:

  • Indiscriminate coagulation testing lacks clinical utility due to low sensitivity and specificity.

Related Experiment Videos

  • Tests yield high false positives and false negatives, leading to poor predictive value for bleeding.
  • Most bleeding risks and disorders can be identified through clinical assessment.

    • Conclusions:

    • Routine coagulation testing is not recommended in surgical or medical settings.
    • Selective laboratory testing, guided by clinical assessment, is more cost-effective and evidence-based.
    • Relying on routine tests can provide false reassurance and misguide patient management.
