Quality control coverage
Verified10%100%
March 2018 to November 2019 · 941 cases / 11,429 H&E slides
The 10% baseline is a general industry practice estimate, not Maccabi's measured prior practice.
Second-read quality control is too labor-intensive to perform on 100% of cases.
Collections: Regulated autonomy

Executive brief
AI enables 100% quality control coverage where manual sampling was previously the only economically viable option.

Before
Perform primary diagnosis on prostate biopsies → Manually review a small sample (e.g., 10%) of cases for quality control
After
Perform primary diagnosis on prostate biopsies → Analyze 100% of digitized slides as a second-read control and raise alerts for discrepancies → Review AI alerts (minimal time cost) and order additional cuts/stains if necessary
Human boundary
AI raises alerts; human pathologist reviews alerts and makes the final diagnostic and procedural decisions.
Why it matters

Work that left the path
Human role before
Perform sample-based manual second reviews for quality control.
Human role after
Review targeted AI alerts on 100% of cases to finalize quality control.
AI role
Act as a 100% coverage second-read control system for all prostate core-needle biopsies.

Anti-pattern
Assuming 100% AI screening requires 100% human re-review.
