Interpretative commenting: a tool for improving the laboratory-clinical interface.

Area of Science:

• Laboratory Medicine
• Clinical Pathology
• Patient Safety

Background:

• Clinical interpretation of laboratory results is vital but varies globally.
• While analytical errors have decreased, pre- and post-analytic phases remain error-prone, risking patient harm.
• Post-analytic errors, including result interpretation and physician action, are a growing concern.

Purpose of the Study:

• To highlight the importance of interpretative commenting in laboratory reports.
• To emphasize the need for improved strategies in the pre- and post-analytic phases of laboratory testing.
• To advocate for enhanced review, interpretation, and utilization of laboratory test results.

Main Methods:

• Review of evidence on analytical vs. pre-/post-analytic errors in clinical laboratories.
• Analysis of factors influencing the expansion of interpretative commenting.
• Discussion of the role of training, quality assurance, and clinical audit.

Main Results:

• Significant reduction in analytical errors, but pre- and post-analytic errors persist.
• Interpretative comments can improve communication and patient outcomes.
• Factors like new tests, guidelines, and clinician satisfaction support interpretative commenting.

Conclusions:

• Greater efforts are needed to facilitate the interpretation and utilization of laboratory results.
• Interpretative commenting, coupled with professional training and quality assurance, is key to improving laboratory medicine quality and patient safety.
• Addressing pre- and post-analytic phases is critical for minimizing medical errors.
