Medical errors in laboratory medicine and blood transfusion are common, especially in preanalytical and postanalytical phases. Improved detection and technology are needed to reduce these laboratory errors.

Area of Science:

  • Medical error analysis
  • Laboratory medicine
  • Blood transfusion services

Background:

  • Medical errors are a growing concern, particularly within laboratory medicine and blood transfusion.
  • This review addresses the prevalence and nature of medical errors in these critical healthcare sectors.

Purpose of the Study:

  • To review the existing literature on medical errors in laboratory medicine and blood transfusion.
  • To identify patterns in error distribution and detection methods.

Main Methods:

  • Conducted MEDLINE searches and manual literature reviews, focusing on the last 8 years.
  • Collected institutional data on preanalytical error frequency and types.
  • Analyzed study designs, data quality, and error classification methods.

Main Results:

  • Significant heterogeneity in study designs and quality, with limited data and no universal definition of "laboratory error."
  • Most errors occur in the preanalytical (before analysis) and postanalytical (after analysis) phases, not the analytical phase (13-32%).
  • Error detection rates varied significantly based on methodology; process analysis yielded more errors than complaint-based systems.

Conclusions:

  • The heterogeneity of current literature necessitates more rigorous error detection and classification methodologies.
  • Evidence points to the preanalytical phase as the primary source of laboratory errors, requiring targeted interventions.
  • Implementing advanced technologies and utilizing clinical audits are crucial for reducing medical errors and addressing organizational issues outside the lab.
