Measuring errors in surgical pathology in real-life practice: defining what does and does not matter

Area of Science:

• Pathology
• Medical Quality Assurance

Background:

• Surgical pathology quality assessment is crucial for patient safety.
• Traditional quality measures may not capture all diagnostic errors.
• Blinded review offers a systematic approach to evaluating diagnostic accuracy.

Purpose of the Study:

• To review the methodology and results of implementing blinded review in surgical pathology.
• To assess the effectiveness of blinded review in identifying quality issues.
• To determine factors influencing error rates in surgical pathology diagnoses.

Main Methods:

• Description of the blinded review process in surgical pathology.
• Analysis of error rates based on individual pathologist, specimen type, diagnosis, subspecialization, and number of reviewers.
• Correlation analysis between error rates and workload.

Main Results:

• Error rates in surgical pathology are associated with the individual pathologist, specimen type, diagnosis, and subspecialization.
• The number of pathologists reviewing a case influences error rates.
• No correlation was found between error rates and pathologist workload.
• Blinded review is a relatively unbiased and effective method for identifying significant clinical errors.

Conclusions:

• Blinded review provides a realistic and fair method for quantitative quality assurance in surgical pathology.
• The method is effective in identifying errors in clinical practice.
• Integration into interlaboratory review processes can enhance its utility.
• Addressing the workload is a consideration for widespread implementation.
