Digital pathology implementation in a private laboratory: The CEDAP experience

Area of Science:

• Digital Pathology
• Laboratory Medicine
• Medical Imaging

Background:

• Digital pathology adoption is increasing globally.
• Laboratories face challenges and opportunities during this transition.
• This study details a private laboratory's digital pathology implementation.

Purpose of the Study:

• To describe the transition to digital pathology in a high-volume private laboratory.
• To identify and address challenges and opportunities during implementation.
• To validate the digital pathology workflow according to established guidelines.

Main Methods:

• Implemented a high-capacity scanner (Aperio GT450DX) for slide digitization at 20× magnification.
• Integrated Aperio eSlide Manager WebViewer visualization system with the Laboratory System.
• Conducted a two-phase validation process following Royal College of Pathologists Guidelines.

Main Results:

• Initial validation phase showed a 6.8% error rate, primarily from digitization issues.
• Process optimization reduced errors to 0.6% in the second phase, with corrected scans.
• Achieved 96.87% total agreement and 3.13% partial agreement in interpathologist correlation.

Conclusions:

• The implementation and validation of digital pathology were successful, deeming it ready for clinical use.
• Full integration of laboratory systems and new equipment will enhance efficiency.
• Future applications, including artificial intelligence, are anticipated to maximize digital pathology benefits.
