Surgical pathology sign-out. Routine review of every case by a second pathologist

Area of Science:

• Pathology
• Medical Quality Assurance

Background:

• Routine pathology review is crucial for patient safety.
• Limited data exists on the accuracy of surgical pathology sign-out.

Purpose of the Study:

• To evaluate the cost and effectiveness of a dual pathologist review system in surgical pathology.
• To determine the error rate and clinical impact of discrepancies found by a second pathologist.

Main Methods:

• A 1-year study involving 5,397 surgical pathology cases.
• Implementation of a quality assurance system with mandatory second pathologist review before report release.
• Analysis of discrepancies for clinical significance and potential impact on patient management.

Main Results:

• Fourteen discrepancies of potential clinical significance were identified (0.26% error rate).
• Seven discrepancies (0.13%) could have led to different clinical interventions.
• The dual review system increased costs by an estimated $7 per case, or $2,700 per significant discrepancy.

Conclusions:

• The dual pathologist sign-out system is effective in detecting clinically significant errors.
• The cost-effectiveness requires further investigation and validation.
• More research is needed to establish routine surgical pathology sign-out accuracy benchmarks.
